Do you have Prime? You could probably have one shipped right to the convention, if you're staying at a hotel
yeah i do. but id probably have to shell out $35 to get it there.
Overnight shipping, for Prime, is generally $3.99 per item.
I bought some stuff at 1am today and used it...
Alternately: http://www.microcenter.com/product/422320/NTE960_Integrated_Circuit_-_3-Terminal_Positive_Voltage_Regulator_5V
Not a buck, but it could get you along through the convention.
That, and some capacitors, some soldering, and a protoboard
i need to be able to pull 3amps at once. and there is no room for a heatsink for that regulator
So you want something like this: https://smile.amazon.com/eBoot-LM2596-Converter-3-0-40V-1-5-35V/dp/B01GJ0SC2C/
Page says it can do 3A
sorta. but it doesnt need to be adjustable.
Most of the cheaper ones are.
i cant find anything on amazon that i could get primed to my friend's house either
that could work..... but still cant get it there fast enough. i think im gonna just rip apart a cheap usb car charger to get the board inside
Those usually only do about 1-2A, so keep an eye on what you're buying.
dang. actually i think i only need 2 amps.
Here you go @junior dust and @wicked horizon this is in case I can't get the ubec replaced before show and tell. I know you guys liked what I was showing the other week 😺
Shiny!
yissssss metallic spray paint
also, its more shiny when my leds actually have power.....
Hey @lusty siren do you happen to know the typical amperage output of a desktop usb port? because my usb ports on my desktop can handle the electronics (minus the fans)
Uhh, well.
USB Spec is 0.5 amps.
Do your usb ports comply to spec? Probably not.
If I were to guess, I'd say no more than 1A
ah
A USB Battery Charging or Power Delivery port can handle more power, and your USB port might be overbuilt for safety even if it's just a regular USB port
USB 3.0 can deliver up to 0.9 amps by itself
and a battery charge/power delivery port can reach up to 5A
if the port happens to adhere to USB Battery Charging 1.2, then the port will provide up to 1.5 A without needing a data connection and negotiation with the device
hmmm ok. then i should be good if it only goes up to 2 amps
Just double-check the car charger you intend on tearing apart and see what it's claimed for
mhmmm
@woven relic A USB car charger should have exactly what you are looking at. Any halfway decent Electronics store should have one rated at a few amps.
Yeah I'm gonna go to best buy tomorrow and snag one before I go to my friend's house. She's gonna let me solder it up there before we go to the convention hotel Thursday morning. If im lucky I can get everything done in time for show and tell...
Busy day
Heh... You don't know half of it yet lol....
I gotta be up at 3am to be at work at 4am. Then I get off at 1 pm and I'll head to her house as soon as I'm cleaned up and everything is in my car to go. I won't be at her house till 5-5:30 ish as long as I get out of my house quick enough
Oh, and it's 8:33 pm for me right now lol
Gonna be a LOOOOOOOOOOOONG day tomorrow
Long days are always the best days.
I've had those days before. Go in to work at stupid o'clock, run around like a maniac, do stuff later, finish at stupid o'clock the next morning
I... don't always agree
Mhmm
Oh plus Birmingham is an hour behind me. That's gonna jack up my sleep for the con lol
That sounds even better
Lol nah. Not one bit
I was soooooo messed up last year. Was basically up for 24 hours (even after the 1 hour set back) on the first day.
@woven relic pick up a second USB car charger just in case...
I shall.
At least you go to bed with a sense of accomplishment and wake up satisfied, no? There is nothing worse than going to bed with the self-loathing that comes with having done nothing all day lol
A feeling I know all too well sigh
I ended up going to Wal-Mart. I'm on my break right now and best buy doesn't open till 10. I found one that is a Qualcomm quick charge one that will do 5v at 3 amps. It's a dual port one so I just gotta remove both of the usb plugs on it
3s is 11.1 nominal, 12.6 at highest. That's just about right for car voltage
My weekend project just got much brighter
Holy RGB Batman...
@shut sigil Don't you mean RGBatman?
Ahhh, oops, my bad. 😃
I really didn't expect how small these things are. soldering is going to be fun 😱
You can do it, @proper dirge
@proper dirge micro soldering is the best soldering
@plucky otter micro soldering is passed on to my best mate. I'm terrible at it.
I just did one of them for testing. I see some sort of holding jig for them in my future
Well I've only been soldering at all for a few months. But still. I had to do some stuff with Dotstar strips, and that was handed over to him pretty quickly.
But 0603 is so much fun!
@proper dirge Sounds like a good plan.
That and 1/2 mil qfn and you have yourself an emergency stepper driver repair.
I only need 256 of them soldered
No biggie.
lol
Solder pot to tin the wires?
We had goopy flux that had settled, so one side was nearly solid like wax, and we scraped the wire tips through that every time.
We didn't have a solder pot.
for showand tell here is me with Mixed reality rosie-CI
anybody know where they put the link to join showandtell tonight--dothey still put it on google+?
I am going to try with that as mixed reality communication of the CI
@rigid junco I can try and get it to you here on discord
@lapis jasper with mixed reality think if rosie show to you when you use AR/mixed reality stuff
that is fbx file now
@lapis jasper if you want to Place to your Rosie-CI or modify this Rosie to more jetson like
what program do I use fbx with @clever pebble ?
it's 3D file
and there is way to transport it to obj for example
@lapis jasper unity is one as colin showed in one show and tell
@lapis jasper thanks!
no problem @rigid junco
hey all, how do i join the show and tell in a few minutes?
@lunar venture we hope to see the link here and/or on the google plus page
thanks @rigid junco
for anyone else interested i found this:
will they invite us after the comments? anyone have any guidence as to signing up?
@lunar venture like the video says, go to the google plus page, find the announcement and add a comment (after you have been added to the circle--only needs to be done the 1st time you're on) then look for the link
thanks
I'm debating if I should join or not. All I have to show off at the moment is a tube record player I fixed
I'll try and post the link
here is the link: https://hangouts.google.com/hangouts/_/bq2esviikbd73dydiocjqdsesqe
sounds better to me now @cinder vessel
yeah just cleared up.
video chat is hard
@lapis jasper which kit with sensors for a feather would you say is the best to purchase.
@cinder vessel what do you want to do?
thanks @rigid junco !
@fair vessel nice work!
do you have a feather already?
I do but it may be defective. So I was thinking of getting esp8266 huzzah with wifi
@cinder vessel I just did a project with AWS IoT using only a Feather Wiced--no Pi necessary!
@spice dust how many sensors and automations do you have connected to it?
The feather subscribes to MQTT at AWS and controls a string of Neopixels and a Feather OLED, so no sensors in this case. But your limitation would be the number and capabilities of the pins on the Feather relative to your sensors. What are you trying to do?
esp8266 is a good start. folks in #circuitpython-dev have been using circuitpython on it to talk to adafruit.io
Yeah @lapis jasper I would prefer to use the adafruit services. Amazon Web Services look good but would rather use the Adafruit.
I tried using the Huzzah32 with AWS IoT and couldn't find a way to get it to work. But might work with adafruit.io
It's cheaper than the Wiced, too
This you tube site also has a lot of good information on home automation "https://www.youtube.com/channel/UCLecVrux63S6aYiErxdiy4w"
I used AWS because it's my professional focus and I wanted some hands-on use. But I use adafruit.io for another personal project.
killer show tonight!!
Ah sounds like a sounds like a great idea to combine the work and hobby focus.
well over to live broadcast
@cinder vessel I somehow convinced them to buy me a bunch of electronics and most of an oscilloscope in the name of IoT research!
Awesome - lol
Woooooo!!! Nerf gun is all working!!! And only 2 hours late.... Oh well. There's next week I guess
I'll get on the show-and-tell next week, I'll try finishing up this record player this week and show it off then
If I have a concept and want advice on it, can I ask on show and tell?
@cunning quest show and tell is a very short fast paced segment. Try asking in the #help-with-projects channel
Yeah, Show and Tell is "I made a thing! Isn't it neat?" And everybidy goes "Yeah, that's cool!" And then repeat.
Yesterday had... 12 people? In the span of what, about 25 minutes?
@cunning quest you can try asking on Ask an Engineer (follows show and tell), but if it's a very vague or broad question, it can be difficult to answer. "advice on concept" sounds like it might be one of those.
@cunning quest you can also try just asking here on discord in #help-with-projects (edit - oh that was already mentioned)
Thanks guys!
Been working on https://pinout.xyz/phatstack this evening
The precursor to a more general "does this board work with this board and what problems might I have" tool
that's a lot of hats
You can never have too many HATs!
I was trying to figure out why this 3-way adapter produced half-wave rectified DC in opposite polarities on the "low" and "medium" setting when my scope ground touched one of the wires and let the smoke out. The blown component appears to be a "quadrac" (combined diac and triac in a single package) in an old TO-105 case. The circuit seems to just put a diode in series for "low" and a diode going the other way with a non-adjustable triac dimmer in parallel for "medium". #Sparky
My pops is moving and he have this old Reciprocating Saw so i decided to make my own portable gun, still not done want tp make a couple cut out so i can see more of the blue leds. 4.5v battery back red laser and 8 blue leds push button
Remember, boys and girls..
Never rework on a breadboard 
And the final touches were done today to get it ready for clay and casting. It's drying now after I gave the whole thing a shot of clear coat, and now I get to go home and sleep. For tomorrow, I sculpt details and make my mould!
@bitter valley an amazing transformation. Nice work!
Blinka PCBs
isn't it? 😃
there is that place on the back of the neck where the routing tool didn't quite make it right
I'm making a new version that fixes that, and I'm wondering what to put on the board
I have a led in the eye already
considering a speaker
@cunning lava you were very generous with the size of the pads.
I was worried about soldering the components, but I think I can pull it off.
I just used fritzing's default footprints
they tend to be one size too large, because they assume hand soldering
Well it's a good thing you did. Much appreciated. Not sure when I'll grab the parts and start working on it, but it's a very cool board just to have.
I already have a second version, with the neck fixed, a led in the eye and a place for a piezo speaker
@cunning lava wonder if you could make the bottom row of 'scales' be alligator pads?
I tried that, but the vias spoil the looks
the vias couldn't go through the round part of the scale segment?
then you can't have silkscreen on it
and fritzing can't do blind vias
hmm
actually I'm doing the soldermask layer separately anyways, so that could work
oh. and then there's the parts on the back side. looks like a usb connector?
@cunning lava Those look amazing!
but along the bottom, where the alligator clips might go, looks like a usb connector?
@cunning lava 2.0 version sounds so awesome!!!
https://oshpark.com/projects/KiSwS9qp <-- the blind vias don't look too bad, at least in preview
each coil is a whole pad, so each is just one pin
not one per segment
but that gives 4 pins, 2 of them have touch sensing
Very cool!
one problem, I can't seem to be able to program this chip, might be some mistake on the pcb...
hi @stark hazel ! you won a #sparky pin! Please email sparky@adafruit.com. Congrats!😀 
awesome!!
I was working on making a replacement light for my license plates using an LED backlight module https://www.adafruit.com/product/1622 and things got a bit smelly when testing on a breadboard (placed the resistor in the wrong breadboard pin)
Haven't shared any updates of the helmet build in a while, so perhaps I should rectify that.
For those that don't read the rest of the posts on my page, I decided to scrap the clay detailing I have for now and focus instead on making a glove mould of the barebones helmet. That will give me a solid base to sculpt on later if I find that I have the time and will allow me to cast the electronics housing as a separate piece. With the housing and LED ridges casted as a separate piece, it would also be far easier to wire everything together since I won't be wrestling with the entire helmet. Instead, I will be wrestling with a part that was specifically designed to house the electronics. I learned that from my previous Neopixel build; the facemask that I wore at Bronycon in August, electronics are best integrated when working with the smallest portion of the costume possible. If I play my cards right, I could even make several different electronics housings that I could swap out whenever I wanted to give the helmet different styles while using a minimum of materials. This would be in addition to the removable facemask portion of the helmet which is also going to be casted as a separate piece.
Thought it would be nice to post some pictures of my show and tell appearance from 6/24/15 https://www.flickr.com/gp/83387518@N07/20BpJ5
@bitter valley That looks great! Modular electronics design is the way to go.
@bitter valley Yeah, being able to swap componenets would be cool AND helpful for upgrades/fixes
@warm lantern Those LED backlights might not be rated for "outside" use. Rain, snow, salt, UV, etc might get to it so I don't know how long it will last under those conditions.
I was planning to coat them in epoxy, but found a different solution anyway. It never got past the prototype phase
I think they have replacement LED bulbs on the market, I even switched out the small bulbs in my old flashlights.
The other thing is that I am rapidly running out of money. I can't find any platinum cure silicone in larger sizes than the Smooth-On trial sizes. I've got two of those, but I don't know if those alone will be enough to cover the whole helmet.
@bitter valley I feel your pain. Visited this "candy" store in NYC but couldn't afford to buy anything. http://www.sculpt.com/ Maybe they've got something as an alternative.
I was prototyping an arduino-based automotive device and I was testing with a cheap chinese SPI LCD display. I had a 12V feed into the banana plugs on my perf board and then an inductive voltage regulator drove the arduino, lcd, and other parts - to simulate conditions in a car. I accidentally hooked up VCC on the LCD to the 12V rail and release #sparky. That LCD got REAL BRIGHT for a split second. The worst part was that I was delayed about 4 weeks to get another $5 LCD from China. I've since moved to Adafruit PID1480 because I can have them in a few days if #sparky pays me another visit.
It's amazing how quickly #sparky escapes; blink and he's gone
Amusingly, I've accidentally run >15V through an ATMega328 + 1.8" screen. It didn't WORK, but as soon as voltage was restored to proper it began functioning just fine
Probably the worst thing I have ever done to a board. Extra crispy.
@lusty siren looks like a good #sparky?
@bright hull That took Sparky into a back alley. Don't leave reflow ovens unattended, kids!
👋 Hello fellow Adabots 
My team is a sponsor at https://hackprinceton.com/ , starting Nov. 10th.
I got to pick out the hardware, so naturally I went with Adafruit!
A lot more resources will be added to this list,
but I thought I'd share it here for everyone anways!
https://github.com/Ark-IoT/ark-hackprinceton/tree/master/hardware
note:
I am fortunate enough to get paid for my work.
All of my personal work--and my teams' work--is free and fully-open-source ✊ ,
but I feel it's an important disclosure to make 👍
I'm a geek and a tinkerer
,
and I love Adafruit and active communities like this.
So I'm here to share all the cool stuff I get to play with!

@sleepdeficit#8709 Cool! Anything to see what projects came out of previous hackathons?
@leaden frost
This is our first year participating with them,
but there are several videos on youtube of prior hackprincetons!
HackPrinceton Fall 2014 Final Demos
Failure is always an option. #sparky
@bitter valley Jellyfish Fortune-Cookie? 😜
halloween pumking
Attempted brush mould.
i was thinking you was trying to do pumpkin cyborg helmet for halloween
The mold is for making the parts in fiberglass.
Nice!
That looks fun to play with!
Fail, rinse, repeat! 🤓 👍
Failure in this hurts big time though, because Smooth-On is insanely expensive. I basically flushed $40 down the drain with this failure.
After watching some more videos, I'm seeing people stiple on very thin layers. Lesson learned. Small batches.
Well my nerf gun fan was a HUGE success this past weekend at my small convention. everyone LOVED IT SOOOOOO MUCH!!!!!
@woven relic What, nobody said it blows?
You had a lot of fans, though?
many!
@bitter valley What Smooth-On did you use? Mold-Max? I just did a pour this morning with the wife, testing it when we get home
nvm, just saw the Rebound 25 in the background
@bitter valley
You should have seen my first few attempts at hot-air reflow work 🤣
That sucks, but you'll get it! 🤓 👍
Ok so - If people remember I started to build a Console using a UP Board but while I waited for that to arrive. I relzed I had no "modern games" to play on this console that I want to make. https://i.imgur.com/c3UQniD.png

So I started to port Doom Levels to Unity3D. No gameplay yet...
So yeah
ajksljgasg I can't wait til I can work on electronics again
oooh raven ridge might be coming out tommorow 😄
The AMD Acellerated Processing unit
Plaster is poured. Now I wait.
A 16-color BMP file displaying on a ST7735 display.
^-- some progress with the graphics
Oh nice 😄
Boom. Cavity mpuld.
One that I will not miss too terribly if I have to break it to get my part out of it.
@bitter valley No. 1 pottery plaster, or something else? I need to cast something tonight but I've never done plaster before and have a question. How warm does it get when curing? If I have plastic wrap touching it will it melt?
Plaster of paris.
And I don't think it actually got all that hot. Plastic wrap might be ok, but I'd run a small test before you commit to it.
Looking at casting a saran wrap and tape dummy?
I've got an electric tea kettle (that I still use) that's the right shape for my cast and it's made of plastic and metal. I decided to go with a ziploc taped around it instead of saran wrap because it's a little thicker. I'm most worried about direct damage to the kettle and secondarily worried that the ziploc will melt and stick to it.
Just build a box out of foam core and hot glue.
The one I built worked perfectly.
It will definitely ruin the kettle.
Mold making is a very wasteful process, so for things like containers for box moulds, build them out of cheaper materials you may have on hand.
No, no, I'm using a cardboard box wrapped in plastic for the form and strapping the tea kettle across the top (wrapped in plastic) to leave a depression. The tea kettle shouldn't touch the plaster. I'm just a bit worried about the heat. Too late now! We'll see how it works out...
I was in charge of ordering the kits,
You think they'll like? 🤓👍🏼

Thank you for the Educational Discount @rustic stag !
I am terrified by fursuit heads. I don't know why, they just terrify me.
Haha I understand.
I find it even worse when someone isn't wearing it. It almost look like somebody chopped the head off someone. but if they were a real humanoid animal.
so I made my battlejacket glow
https://imgur.com/2epMtXO
@crude quiver Nice job!
conductive thread is a pain in the butt, but its worth itbecause now I glow in the dark
@crude quiver That's great, what board did you use to drive the lights/neopixels?
flora + bluefruit flora board
Now that you are an expert at setting up all the hardware, you can move on to making fancy animations selected by the joypad on the bluetooth app.
that's the plan, I just wanted to get it working first
it's great when you see all the lights come on.
It's too bad I don't have an Alexa to connect to... https://youtu.be/EXIOPjuGkl8
Adafruit Circuit Playground Classic and Neopixel strips in a cardboard box. Some kind of light up thing for something that lights up.
@whole elk thank you. I talk a lot in the electric fursuits telegram too. They've helped me soooooo much with learning electronics. I haven't been on this discord as long though
That's why I'm here xD
I'm planing to give my head some fancy LED eyes ( neo pixels ).
@thorny bluff Nicely done!
One... “jellyfish.” Need to attach some sparkly ribbon for tentacles...
Its basically “cosmic turtle” meets “florabrella” with a LOT more LEDs and some fiber optics.
Tyvvm @scenic siren
You nailed it. It's lovely!
My IoT Pumpkin is live. 😄 It listens for tweets containing the word "pumpkin" and any valid CSS named color, then switches to that color.
Link dump inbound!
Trying to use a DHT11 connected to a arduino to interface with my cayenne database. I plugged it in and went to check the website. I look and it was reading almost 800 degrees! Turns out the cayenne virtual ports can't get sensor data on pins 0 and 1. I switch to port 2 and it works perfectly! I stayed up for 14 straight hours thinking it was broken...
@cunning quest we've all had those moments where we tirelessly chase a problem down a rabbit hole and it end up being something simple like that.
Glad you got it sorted out!
I had stay late at work one day because something cruicial wasn't communicating with the master node
spent 4 hours trying everything
turns out the communication cable was just unplugged
Rip
debugging pro tip: always make sure stuff is plugged in first
Yes
My issue was that nowhere in the cayenne documentation did it say that you can't use those ports
did get a chance to do some useful firmware upgrades while we were doing this
so not a complete write-off
related: my light up patch vest was a big hit at the halloween bar crawl last night
I was in a half-dozen snapchat videos
Basic tile and sprite engine functional, now to speed it up.
This time, in video!
@cunning lava, what data type are you using to reference your tiles? If you're using anything more than an unsigned I nt per tile, you probably need to optimize.
I'm using half a byte per tile
I wish I could use a whole unsigned int, but there simply is not enough memory for that
You only get 16 kinds of tiles on a layer
There ya go.
Facemask is curing.
Now taking a break while I prepare to do the helmet.
Mentally...
After rewriting a part of the code in C, it's fast enough to walk around the screen.
@cunning lava That looks great!
It's not as smooth as I hoped, but workable already. I could still rewrite more to C
CircuitPython is slow with bit manipulations
Internet of Pumpkin now has a livestream so you can see it change: https://www.youtube.com/c/JonSwope/live
You can change this pumpkin's color via Twitter! It chooses its color by listening for public tweets containing the word "pumpkin" and a CSS named color. No...
@bitter valley aww, that ain't too bad, nothing that a little duct tape can't fix. That's pretty good if it is your first attempt at doing the molding stuff. Maybe there is some kind of depth gauge-thickness applicator thingy the pro's use.
@marble tapir one time there was an app that let you change the color of the lights for the Empire State Building in NYC.
I decided to just use my existing facemask and switch up the lighting scheme a bit.
@marble tapir How does it work ?
My buddy wants new leds in the fursuit head he is rebuilding. Said he wanted to be able to change color so i did that nicely. just waiting on the head to arrive from him and the trinket m0 that I will use to run it though no circuit python right now because I dont know it yet. The 4 leds under the sheet of paper (used for a diffuser) will be cut into 2 sets of 2 and each set will be mounted behind the acrylic eyes (they are clear but will have a defuser in between them and the lights) and will light up the eyes nicely. The little strip of buttons will be velcroed to the inside of his arm sleeve so that they are easy to access
@onyx grove I have a RPi Zero W with a Pimorni Unicorn pHat on it that is running a script that is subscribed to a certain API Twitter exposes that will stream you tweets based on filters you provide.
It is taking all tweets that say "pumpkin" and then looking for a valid color in the text of the tweet.
And then I have an RPi 3 + camera that is livestreaming to youtube.
If I do this again, I'm going to do a "Twitch Plays Pumpkin" sort of thing and let everyone change the H component of an HSL color instead.
Oh.....Nice.....
hi @slim sierra ! you won a #sparky pin! Please email sparky@adafruit.com. Congrats!
Hmm, I guess I should post my first attempts at reflow: https://hackaday.io/project/10491-lodestar/log/35673-desoldering
I tried to reflow the board, with extra flux added, to see if that would help. It didn't, so I decided to try and recover the LEDs from the board... And I learned why they use temperature-controlled hot-plates for this:Yes, that is melted plastic from one of the LEDs...I guess that's a failure... Good thing I have excellent ventilation in my kitchen.
@brisk pond

Thank you!! 
@cunning lava
Ouch! 
It looks like something that fell off a 'non-electively decomissioned' Terminator!
I used my kitchen stove to do the reflow
worked two times, the third time I left it on too long
@cunning lava
😬
So 3rd time definitely wasn't the charm in this case ..
now I have the hot air gun — the best spent $40 ever
@cunning lava
Nice!
I finally got a decent soldering station a little while back,
and couldn't be happier.
Good equipment does wonders on self-esteem 😂
(If this is the wrong place for this, absolutely let me know, and I'll remove it)
My team bought all Adafruit gear for the hackprinceton Hackathon!
If you want to see the kits we put together,
or would like to use or contribute resources to the hardware wiki;
it's all open source, and everyones welcome! 🤓 👍
Here's the wiki page!

hokay, halloween is here. I can consider my costume done.
the shoulder and arm mounted things are neopixels, and animate with the top two buttons
everything is adafruit, including the control box, which is what adabox005 came in 😄
https://witches.town/media/zg-2LXPiuVKt2l3bGPI is the inside. using CP.
hmm, so it's like your real arms are robot arms?
yep!
I'm glad you got that. I didn't do a very good job of making it look that way so most people didn't see
that's really clever
it's based on Super Dinosaur, a comic by the Walking Dead guy who wanted something appropriate for his kids https://static.comicvine.com/uploads/original/14/142946/3763328-1629143068-Super.png
I wanted to have speakers/piezos but ran out of time. and the "gatling" animation is a lil buggy
well, the things we could do if we had infinite time...
@plain stream I love it!
@urban gulch Hey! Great job!
@urban gulch Definitely! I'm so glad we figured it out. Congrats on your first Python project being awesome!
wow, that looks really cool!
The remote
The board in place
The ugliest piece of permaboard soldering I’ve ever done.
@brazen crag Haha, too cool. That's retro goodness.
I was doing a write up about it and I got an automated message to watch my language when I posted. I’m not sure what I said but it killed my whole write up.
Thanks @calm sparrow !
@brazen crag you're welcome!
@brazen crag Nice! And to think Dr. Adler, who invented the remote, helped me once on a project I was working on. He would have thrived here in this Discord.
I just did another write up and the bot killed me again for language!
I saw that. What did you say?
Can I post a link here?
@brazen crag Yes. There's a few odd words that the bot still catches. We're still teaching it.
Then let’s try this. Let me know what upset the bot. :-)
Whoops!
Let’s try that again...
I’m going to try each paragraph in turn and see which one causes it.
The pictures I just posted are for a project to build a retro bluetooth remote. The board inside was the same size as a piece of permaboard I had so I put the eight buttons on one side and a Bluefruit Feather on the other.
Okay. That second one.
“Flipping the board”? That would be funny.
I can't figure out what it would have caught.
I sure didn’t want to earn a #sparky on this project, but now that I’ve killed a Bluefruit Feather and have to re-build the whole board, I figured I should at least submit my nomination. 😃
@brazen crag I removed flipping from the bots list
Then let’s try one more time...
The pictures I just posted are for a project to build a retro bluetooth remote. The board inside was the same size as a piece of permaboard I had so I put the eight buttons on one side and a Bluefruit Feather on the other.
When I went to test it there was a short between two buttons and one button was dead. I spent a lot of time flipping the board over to test then disconnecting to solder and back and forth.
Then I accidentally put the soldering iron against a pin while it was still plugged in and I heard a high pitched whine.
Now the two pins I was trying to unstick won’t work at all. I killed them both.
@lapis jasper it seems to like me now!
ok perfect! the previous deletions got truncated so I didn't know what they were upset about
This taught me that for long write ups I should always make a copy before hitting submit. Just in case.

So for my Halloween costume, I made this cool electronics based costume, but on the way to go trick-or-treating this happened #sparky
@woven dagger That happened to my LiPo a while back. Fairly easy to solder it back on
careful with heating lipos
ah, but that's just the protection circuit board in there
I tried to solder it back on, but my sister really wanted to go
You can see that I tried to solder one on
@woven dagger Yeah, it's not necssarily the quickest job, but you don't necessarily have to write off the LiPo
@elfin bison is the cat OK?
I love that, even behind a pi zero, the camera's facial recognition/focus works.
I think I did OK for a first time work on a perf board where none of the holes are connected. I mean, It could be a LOT worse.
The header pins have not been trimmed down yet either
Hey all I finished glados! Beta version anyway! I'll have video soon
But here's a preview pic

Anyone around with a Pi Zero W, a blank SD card, a USB -> MicroUSB cable, a computer and a desire to play with a shiny ground-up, MicroPython-inspired embedded Raspbian spinoff aimed at beginners?
Uh... You know, I have these things. But my gut feeling is I'm not sure how that's better than the Python tools that come with the Pi already
in terms of learning
you know there is a port of micropython to rpi bare metal?
but it's highly experimental
Trouble with MicroPython is that it's not Python
also PiCore Linux
It's designed with kits in mind, for the most part, where the kit contains a Pi Zero but the idea that an end-user has to hook it up to a TV, somehow add a USB hub to add a mouse/keyboard, boot it up, connect to WiFi, install some stuff, etc to get a project up and running is perhaps a little far fetched- at least it's panned out that way from experience
With this approach, just stick the microSD card in, hook it up to your computer, tweak the project via Mass Storage, unplug and deploy
I'm starting to see it, but I'm not 100% there. You can already configure the USB OTG plug so the Pi presents itself as a network or serial device, for example, for one-wire use
And you can drop SSH and wifi info files into /boot to prevent the need for peripherals just to access the system
that also enables VNC
The other side is, well, the Pi Zero is a $5 board, and the W is $10, and that's pretty good for python-compatible boards
But is there likely a beginner's project which would benefit from running the board bare metal vs. traditional Raspbian, given e.g. the lack of ADC?
Yep! Absolutely- since traditional Raspbian has proven quite explicitly to be just too much of a hurdle for some users
Whereas "unzip this onto your SD card to have project files you can edit from any host PC" - like MicroPython but with a ground-up cut-down Raspbian running a full Python 3.5 in ram - should make it "drag and drop simple"
You know what...
@stable plover i did something similar a while back based on the cloud 9 ide, what's your approach?
Ah yes and Beaglebone Black had Cloud 9, I always liked that
if you could keep HDMI output (optional), console output, and USB HID keyboard input, and you put a full-featured REPL environment on there like a bpython port, and you followed what this article posted in #books-and-tutorials said about designing educational programming environments... http://worrydream.com/LearnableProgramming/
Mine's just to keep it simple, with a main.py on mass storage that's reloaded when it changes, with debug output over serial
this could actually be pretty awesome
The one thing that trips me up is having to take the card out and put it in a different system. For a beginner, that's a significant step away from concrete interactivity and experimentation
Yeah, fortunately we can ship pre-flashed cards to eliminate that step
But you have an entire Pi's worth of RAM and CPU time
Just found my HDMI cable bent at 45degrees, what the deuce!
So it's a BYO IDE approach at the moment, which certainly has its disadvantages when it comes to auto-complete etc
Hey guys, I finally made a video for my sign-language hand project
My first video! This is a sign language hand built from an Arduino and a toy! I made this for my STEM club and worked really hard on it. Everyone else was us...
hi @elfin bison ! you won a #sparky pin! Please email sparky@adafruit.com. Congrats! 
@woven dagger That's frakkin cool!
I finished making my portable record player electrically safe, with an isolation transformer

I'd really like to show it on today's show and tell, but I'm not sure if I'll be home before it starts or not
I made it!
I think I submit my interest in showing somethign tonight... I guess I wait & see.
half an hour to prepare 😃

this is my node-red dashboard, served on a raspberry pi zero w, with local mqtt server and a pair of ESP-01's with BME280's as sensors deep sleeping for approx 10mins. 700mAh li-po batteries gives me approx 3 weeks of service because I didn't desolder the red LED's
I think the abberant peaks and valleys are wind influencing the outside sensor. They're particularly sensitive
@twilit kettle Been there, done that. Eventually bought all the wires.
@karmic fjord i was linking up a mikroe ble click 2
it actually worked suprisingly
@twilit kettle I’ve also used f-f wires with a bit of header that has long pins on each side.

@urban gulch Love it!
Brilliant.
I made these for Halloween! https://learn.adafruit.com/3d-printed-led-fire-horns/overview thanks to @wicked horizon and @junior dust
@candid acorn I see it now
I tweeted the model a bit, so I could mount the trinket inside the horns... that took a bit to learn how to do in Fusion360. Working with the mesh and converting to BRep and then getting the mounting holes right etc... but I finally got it 😃
I decided to go with the option of powering the LED strips seperately from the trinket. My original setup was two trinkets, but this way I could do just one trinket and two seperate strips wired together and the battery pack lasts a LOT longer
@candid acorn they looked awesome. Must have been fun watching people's faces as they reacted.
Yeah, I had a LOT of compliements 😃 I'm a novice a soldering, so it took awhile to get everything setup correctly, but it was worth it! 😃
Totally. I am alright at soldering but can't make the leap into 3D printing. It is super impressive to see what people are developing.
I'm addicted to 3D Printing! I've had one now almost a year and I love it.. It can be challenging at times and a bit frustrating, but when you build something from an idea and then can hold it and use it on a daily basis!?! Nothing like it!
I think it is the initial cost that is holding me back. I feel like there would be hidden costs that I wouldn't factor in before picking one out.
Yeah, the filament isn't too expensive, but you want all the little tools... so stuff like a knife spatula, diagonal cutting pliers, rubbing alcohol, sanding sponge or paper, etc.. so it does add up. I guess it just depends on how much post printing touching up you're going to want to do. You can get a CR-10 for ~$400 and filament is typically in the $30 for 1kg roll.
OKay, then you have an enclosure
Highly recommended if you are going to print in ABS
Lastly, you're going to REALLY want to make sure to keep your filament dry. I learned that the hard way... it does make a difference.
Probably should post in this in 3d Printing
Here is a good article on hydrolysis: https://www.matterhackers.com/news/filament-and-water
@halcyon thorn honestly, if you are a tinkerer, it's pretty easy to build a decently inexpensive 3d printer. All you really NEED is a machine that is true, and moves accurately. Stepper motors and decent rods take care of that.
Besides, let's be honest here. I'd be very surprised if 90% of the people in this server aren't going to deconstruct their first printer anyway so the can rebuild it better.😃
@candid acorn thank you for the link. We got a bit off topic here but it was helpful. It seemed like it would take a lot of little things to get started.
I'm in the middle of building my second printer. This time out of wood, and the cheapest parts I can find
@proper dirge do you have a link to some plans to build one from scratch?
@slim sierra nice haul.
@halcyon thorn not really. I've just been looking at loads of youtube videos for my inspiration.
@halcyon thorn Yeah, it was a bit off topic, but those are things you need to think about when getting into 3d printing, bc I can be frustrating when your prints are failing and you don't know why.. or they don't look good... so there is a TON to learn 😃
Honestly though, most 3d printers are a solid box with some rails that allow x, y, and z, movement. Clearly there are higher end features that are available, but a basic printer is a fun project\
I follow so many people in the 3d printing community on youtube and twitter... good place to start
16x16 Neopixel Matrix on a Huzzah Feather (ESP8266). The jar next to it also has about 15 pixels inside to help amplify the radiating of the "fire". Two 1/4" pieces of acrylic (lightly sanded) are on top of the pixels to help further diffuse the light. I'm moving alot of my LED projects to FastLED and in the process I've learned more about color than I thought was possible.
@grim basalt That's really neat!
So cool @grim basalt
@grim basalt very sick. The jar was a nice touch. Added to the ambiance.
Highly custom arcade stick.
Took me many minutes to construct, very high quality. Proud of my work. Better than any other enclosure out there.
It was sarcasm. It's made out of a shoe box @cunning lava
nothing wrong with shoebox in general, but in this case it might be a little too flimsy
are you prototyping?
Yeah I'm using it to figure out my layout while I wait for the enclosure parts.
makes sense
I'm still in the process of designing labels which will be the most frustrating.
what will it be made of ultimately?
an ABS enclosure.
I was going to construct one from some cedar panels but went against it in favor of pre-fab ABS enclosures.
I have to build 2 of these so constructing 2 boxes from cedar (I'm not a carpenter by any means) would be especially challenging.
that's much lighter
Yes, but they have suction cups and I have flat top mahogany tables in the living room
are you using abs sheets or 3d-prrinting it?
convenient
You can purchase them off the shelf.
Yes.
@cunning lava Woops sorry, it's Acrylic not ABS.
@magic dome But that shoebox is the best thing ever. 😄
@magic dome if you use aromatic cedar the controller would smell lovely! (I too love the shoebox prototype)
@halcyon thorn Hmm. Cedar arcade controllers. Cedar handheld gaming controllers. With wooden buttons. You might be onto something.
cedar gets splintery....and oily. i would go with something like walnut or mahogany. 😄
Hmm, that explains gaming rage. It's not the game itself or the emotional control from the player....it's literally grabbing splinters of wood. Wouldn't you throw your controller down if that happened to you? 😛
my node-red dashboard also notifies me when there's a problem!
Building my table centers for my wedding, 3 down another 7 to go 😂
It's a neopixel ring, esp8266 and a couple of 18650 li-ion cells (with a boost circuit)
(excuse the mess 😋)
That's really cool looking @mystic ruin are those just off the shelf vases/plant holders? They work very well with the light inside.
@mystic ruin Very nice, indeed. Does the light change at all? You could "flicker" it by playing with the brightness in a for... using random().
Oh, nice. Really clever idea. They look great
Thanks @strong phoenix . I have software called mclighting on it that has a load of different patterns built in
Currently its just cycling through colors
Good deal. Blinky is fun, but always more funner with variation. :D
Oh...now I understand why you went with the ESP.
You gonna try and be on the live broadcast this week?
@mystic ruin Those look great! Also, congrats!
Testing begins!!! ("Banking" system to get my kid to practice more school band; has to earn time on my drum set)
@strong phoenix that's awesome. What is it detecting and how do you record the data.
it was. there's two different detection systems. using a LIS3DH for the drum set; this is "expenditures". then i'm using a vibration sensor for his band equipment (snare pad and bells); this is "deposits". all of the expenditures, deposits, and balance are published to Adafruit IO (accounting is done onboard). runs on a Feather Huzzah ESP8266. there's other stuff: hourly (or 30 minutes if there is a system error) system updates, and a NeoPixel jewel (for now) to show current balance and AIO connection status. (my kid is at an age where you have to keep them honest, and he has time alone after school; plus I hope it helps teach him about the value of working for what you want). I need to start a writeup and populate the GitHub I have on the project....

Finished the 9 lights now and am using node red running on a pi zero to control them
@mystic ruin NICE. How many are you doing in total?
9 😃
@stable plover 😃 best screen on the pi
Just setting up a router now that i can bring wiht me on friday
@mystic ruin awesome i love the diffusion the glass adds to the lights
are those the LED rings?
yup
16 neopixel rings
just handier for assembling
There isnt much to them to be honest
just an ESP8266, the neopixel and the insiders of a battery bank
TBH i thought they were til i counted them 😛
they are on pretty low brigthness though
so its more than enough
probably better from a power consumption thing
speaking of those led's -- my esp8266 still randomly turns on xD
@mystic ruin Look great! How are you coordinating the color changes?
thanks @spice dust ! Im kinda doing using something called node red, its a really cool software, its almost like a personal if this then that
So i press one button and the same command is sent to the 9 of them
the command im sending is setting it to rainbow, after that it changes colour automatically
I might try playing around with setting a delay inbetween sending to each one so its more cylical rather than them all changing at once
@mystic ruin I'm loosely familiar with node red. Been meaning to give it another look.
yeah it seems fun, I played around with it a few years ago
it comes pre-installed on rasbien
If im not too tired I'll try go on show and tell later
although i probaby should write my vows or something 😛
I have pictures, but no video. Sorry, my dropbox and my computer is doing this thing where all the video is black

Welcome, @slim cradle!
Hey y’all please go check out my project over on instagram , https://www.instagram.com/proteus_01x_/ I am making a media centre and arcade machine that’s easier to use. I wanted something for my family to use with no problems. I am working on the third version right now. The first version was way to big and twice the size of the new version. The second version had to many switches and hard to understand. The new version is smaller then a piece of paper and will have a user interface instead of having a whole lot of switchs. There are many other features please go check it out! I will really appreciate it
Time to do some research and find out which bits of the chevy volt are opensource
"We used a open source string library because handling strings in C is as close as we get to hell on earth"

busybox, coreutils, tar, uboot, gcc, etc
and what looks like the field upgrade code for the lighting system
I see. I was secretly hoping that GM was doing work and licensing as open source.

I recall seeing a 3D printed car at Maker Faire several years ago. It probably took a year to print. But if you drive in NYC you want it built like a tank to navigate the moon craters in the road, that and for protection when you get tapped by random drivers.

I was able to keep up with the enclosure design part and the electronics until the software stuff slowed me down and at that point its hot glue heaven XD! -- hoping to iterate and improve from what I learned from all of this...

https://blog.adafruit.com/2017/08/29/celebrate-mistakes-together-with-sparky-the-blue-smoke-monster-adafruit-discordapp-adafruit/
The best goof I have from this project is that I didn't plan ahead and soldered these screw terminals to the opposite side of the board from what I needed. Had a tough time getting them back off afterward.
#sparky
Not very exciting and I was able to correct it
@proper kindle a fine example. be sure to add the #sparky tag to your message. (you can edit your previous message and add it)
Does it qualify for the pin then? :3
sure
you'll probably think about this next time you solder on some terminals, right?
Absolutely. They were very stubborn to desolder and I feel lucky that I didn't damage anything in the process, what with all the heat I was pouring into that
heh, I just did the exact same thing only 2 days ago
@proper kindle couldnt help but notice the tall solder joints, consider adjusting those accordingly so they dont stick out too much - might save ya some space too

Both are written about at daveastels.com
@karmic fjord oooh! NICE 😄 which PCB is for what?
The round on id for the humidity/temperature storage sensor. Teh rectangular one is for the light.
retangular is full light in other side?
@clever pebble Right, the neopixel stick is on the underside.
Oddly, Fritzing put pads on each side, with they aren't connected. I'll have to add a via.
@karmic fjord what are you using to diffuse the leds?
Nothing currently, When I get mu printer I'll look at using some sort of translucent material.
@karmic fjord ooh when are you getting it? stock up on some sanding stuff 😄
It should arrive in January.

@cunning lava awesome! i saw your board on oshpark 😄
trying out new lighting gear 😄 Really like the way @rustic stag handles product photos ~
@vernal ferry Nice! I built a tabletop lightbox photo studio using DotStars and an RPi0W. I used it for the first guide I did. Turned out really well!
@scenic siren ooh which dot stars? and cool 😃 you could do multi-colour lighting with it 😃
@vernal ferry I used the white 60LED/m ones. I thought about doing multicolor, but the white made with RGB isn't ever quite white. I have them soldered into 3 squares 9LEDs per side on the squares, mounted on little acrylic sheets and suspended with 550 cord on a PVC frame with a ripstop diffuser suspended into the middle
@scenic siren ooh yeah might need ones with higher CRI for pure whites but should be fine with post processing.
what camera do you use?
Canon 7D
What about you?
I inevitably have to do a little work in post, but I got it down to minimal temp shift and sometimes increasing exposure. I'm still trying to work out a way using mylar to reflect some of the reflected light back into the setup but for the most part it's a solid setup.
@scenic siren My main camera is a Nikon D610. Ive been using poster board x) there's also PVC sheets (used for cars? i guess??) that work as backdrop too
Yeah I have a piece of posterboard blue-taped up to a crossbar built into the PVC frame
Posterboard is cheaper but it does have a fibrous appearance if you're doing super closeup photos. I have all of this mounted into a cheap Ikea table that will work as a clean reflective surface for macro photography if I need, but the posterboard works better for general use.
@scenic siren ah good point on the fibers with posterboard, the white ones are good just to use for bouncing/diffusing lights maybe
@scenic siren using this btw https://www.ebay.ca/itm/PVC-Photo-Photography-Studio-Lighting-paper-Backdrop-Background-Matte-Starlight/192071543098?hash=item2cb85b293a:g:liMAAOSw44BYb29s

Hey everyone! Wanted to share my project 😃 I turned my Furby into a fully functional Amazon Echo and made many, many mistakes along the way. Here’s my build log detailing the project and mistakes: https://howchoo.com/g/otewzwmwnzb/amazon-echo-furby-using-raspberry-pi-furlexa — I used an Adafruit TB6612 to control Furby’s original DC motor #sparky
I also made a YouTube video if you’d rather watch all the things: https://m.youtube.com/watch?v=aCOsM-4NEKs
By combining a Raspberry Pi Zero W (a tiny computer), Amazon's open-source Alexa Voice Service software, and a few other electrical components, I converted m...
@west sable cool! checking it out now 😄
Lemme know if you have any questions! It was a heck of a frustrating build — I actually started it before the Zero W existed and ran into major size limitations with the original Zero and related circuitry. The Pimoroni Speaker pHAT also saved the project
@west sable awesome video and build documentation 😄 I still think furbies are a little creepy but at least 100% more useful with alexa capabilities 😄 do you have a lot of control over the way the mouths and eyes move?
Thanks! It’s definitely more creepy as Alexa. Sort of — so all of Furby’s movements are controlled by a single DC motor and gearbox (numerous gears, cams, and levers). There’s a cam position sensor (limit switch) on the gearbox that tells you its position. So in theory, you could track the exact gearbox position and use that to vary the motor speed and direction to control specific movements, but I decided not to do this due to complexity
If I were to do that, I’d probably change the gearbox out for some servos or at least a stepper motor for easier and more precise control. It’s a pretty amazing piece of engineering for a 20 year old toy that sold for like $50. Probably the first real smart toy
@west sable is that black spot in between the furby's eyes some smoked glass space for something or just decoration?
It’s a light and infrared emitter/sensor. That’s how Furbies could “communicate”
I left it there, thinking about using it to turn my TV on
And in this moment I realize I know entirely too much about Furbies
@west sable never owened a furby, now i know 😄 cool! 😃 and haha a furxpert
Proud Furxpert 😜
Okay, that's definitely going to keep me awake at night.
yeeeh all the black friday stuff arrived 😄
im going to have a go at assembling my first board :3 ~
Also got a quick 957dw+ from the adafruit Store
First time using this and just desoldered a Silabs chip off
@west sable assembling trinket m0s for fun
Cool
And learning! - first time doing a lot of these things >.>
Have you done a lot of soldering?
@west sable mostly through hole kind and with anything else just parts replacements
@vernal ferry Nice!
I was really hoping to go on show & tell tonight but unfortunately the internet is down at my apartment for the week but I still wanted to share with the community my project if anyone is interested. I really loved @terse totem 's idea to use a Circuit Playground Express board with a snow globe and decided to make my own version with MakeCode. I have a write-up here along with a link to the code: https://www.hackster.io/BlitzCityDIY/light-up-musical-snow-globe-c5a901
Hope everyone has fun tonight!
great write-up @fair vessel !
@terse totem thank you very much!
@karmic fjord 😂 thanks for helping check my bom again 😄
Took more photos today, more practice 😄
@cascade#3765 Looks great!
@vernal ferry No worries 😃
@scenic siren thanks 😄 hard to take a photo of something without taking it apart xD
Double the fun!
@fair vessel Neat. I should make some; I have several CPXes sitting around (Yay freebies!)
I’m hoping to get on tonight (with sound! @eager pine I share your audio pain). I have my “charade” project on a PCB now, and I can talk a bit about my Sino:bit explorations if there’s interest.
@fair vessel OK, read it. That’s awesome. Now I need to make a trip to Michael’s. I like the Peanuts theme. It would work as our Christmas tree is an artificial Charlie Brown Christmas Tree (that I scooped up at an office white elephant gift exchange a few years ago).
I like it when a project all fits on one side of the PCB, so that I have the other side free for doodles:
@everyone Show-and-Tell Starting in 10 Minuites!
@plucky otter Looking forward to "more SEM fun"! So cool.
me too 😃 Hopefully it doesn't break again
Well this one isint going to involve a working SEM...
it's a hobby, it has to be expensive
@karmic fjord you can do it! 👍 🎙
Anyone know where to find info on the POV project shown at the beginning of today's show and tell? I'd like to learn more about making a POV display.
@prime star I think it's https://learn.adafruit.com/circuitpython-painter/software?view=all
Thanks @cunning lava
Awesome show!
Fun as always
@cunning lava those doodlesss 😄
@cunning lava love the doodles
@cunning lava The doodles are amazing
@karmic fjord thanks! & that's awesome that you have a Charlie Brown xmas tree. I found the Charlie Brown ornament at Wal Mart and they had a few other Peanuts characters as well
@fair vessel The tree is pretty much our sole nod to the holiday; it’s a bit of a statement. This year it will be joined by a couple PiHut led trees, and hopefully a CPX snowglobe 😃
@lapis jasper played around with the modded hyper last night and figured out how to add/use a library.. so can detect usb events but dont know enough electron to know how to trigger a rpc.'new' event in js x)
@vernal ferry thats where I'm at too
Carnegie Mellon University Library Occupancy Estimator built with ESP8266s.
Available at cmulib.tk if anyone would like to check out.
Can I check it out in person? How does it work? Where does it sit?
It's in Sorrells Engineering library.
The ESP8266s are double-taped onto walls and easy to spot.
For explanation of the project, here are links to my blog:
http://yifangu.com/#/posts/2017-09-12/library-occupancy-project-follow-up
Neat. What are you using as your ratio of wifi devices to humans? (ie depending on what I'm doing I'll have either 1 or 2 (or rarely 0 or 3+).
while I'm walking about CMU my phone is always connected to wifi (unless I left it in my office because I'm a dumbass). If I open up my laptop that's another device. I might have my tablet on me or another laptop as well.
Nice to see neat things from the ol' alma mater. :) I was in social and decision sciences so I didn't get to play with these sort of things too much then
Also it wouldn't be hard to broadly categorize between phones and other devices with an OUI lookup of the MAC address, since many major cell carriers keep an OUI for their mobile lineups specifically, vs. computers which will broadly have generic Intel, Broadcom, etc. MACs
So for a first approximation, it's 1 phone per person, then plus or minus the difference between phones and non-phones
I actually visited the library a couple of times, measured occupancy using tally counters, and did a linear regression with number of devices present.
Well heck, can't argue with empirical evidence
Although interestingly, device to people ratio is slightly less than 1.
Huh.
Most likely because phones don't send out probe requests often enough when locked.
Working on getting a video link
Got some comments that the music was hard to hear. I'll make another video where its louder
This one should be louder.
@proper kindle Very well done!!! That is really good fitment.
Everything works without a hitch (mostly). Now I just need to write some code to control it all
The speakers buzz a little bit though and I'm not sure why. I think they might just be a little loose.
woah
I officially taught my clock how to clock.
Alright, I'll hold off on the sharing to the next big update. Don't want to spam. Just excited that it's finally all together.
the globe lights or the clock lights? both?
why not both 😃
Globe lights off, cover removed, clock on. (It's midnight here)
All lights off, cover removed
;3 oh i meant the room lights @proper kindle /o\ but cool to see the inside of the diffuser
Ooooo lol. Obvious in hindsight. I'll snap you one more later today
@proper kindle projects like that are exactly what #show-and-tell is for! Keep up the good work
huh. so i went to plug in my nerf fan gun yesterday and it puffed smoke at me. Im looking at it right now and 2 different ground connections got loose somehow. So i definitely have a #Sparky moment on my hands lol
Ok!!! Its my Teensy that is dead! kinda sucks but thankfully i have a backup!
@woven relic That's only a Teensy problem.
@lusty siren only just a bit hahahaha
Teensy's are awesome microcontrollers for what they can do but they are so ridiculously fragile. Personally I've only fried two of them but elsewhere someone referred to his workshop as the place teensy's go to die.
@sudden crane what makes them fragile vs. other boards?
I have no idea why they just die with static or some voltage fluctuation or something. I just have a decent amount of anecdotal evidence that they are fragile since I've only used about 5 teensies and two of those died but I've used a bunch of nanos (and I abuse the hell out of these), and the occasional other AVR arduinos and never had a single one fail. And other people have expressed the same sentiment. This could be confirmation bias on my part but I'm going to guess not.
That's pretty spooky
Amazing @keen temple
I was inspired by the book from the movie Hocus Pocus, and of course all the great guides from Phillip Burgess and the Ruiz Brothers.
Brilliant.
@keen temple what display are you using for the eye?
It lives! I've been playing with my new 3D printer and some parts I've had lying around. This will be the turret mechanism for an RC TankBot I'm working on.
looking good @lusty siren 😃
The only reason that even happened is because FreeCad has a gear-maker thing, so I made some gears (Surprise!)
Then I held them up to the gear that I was going to try to use for that (Holes didn't line up, etc etc) and it was the same exact pitch
So instead of forcing the gear I had to work, I made and printed one that was functionally identical but had proper holes and the like
Since I have it pulled apart right now I thought I'd share the cluster chuck that is the inside of my nerf gun fan!
Oh my
lol yeah. its a cluster. but it gets the job done!
Wow! What goes on inside that Nerfgun?
This is mine -- seems like I might need to upgrade! https://learn.adafruit.com/n3rfgun/
@lofty latch Azure has turned it into a literal air gun. 3 fans allow it to blow pretty well
Yep, I need an upgrade! My kids would love it, since they wouldn't have to chase down the darts.
The whole idea blows
@lusty siren I still remember Scott nearly kicking you for that comment the first time before it clicked. 😄
Haha, I'm not surprised
Testing unfurling:
https://pinout.xyz/pinout/joy_bonnet?v=1
@lofty latch like Andon said, it's basically an air cannon. It no longer functions as an actual nerf gun anymore.
@lusty siren it's technically 6 fans
Six fans? What kind of range does it have? Can it actually knock things over?? My boys are kind of excited to see what it does. Might have to make something similar!!
And since I'm done working on the internals again I'm trying to work on integrating a trinket into my lightsaber to control new leds I'm going to put into it. Issue I'm having is triggering the trinket and the original board inside it in sync because I'm using the original board for its sounds and feedback
@lofty latch they are 40mm 1U server fans. The range isn't anything crazy. It's actually used to cool cosplayers and my fellow fursuiters when I'm at conventions. And to be a prop weapon that looks all flashy and stuff
So, its really a cooling fan! Cool. (pun)
Yeah it really blows
I made a gun for a Bastion costume that had sound in the gun and in the suit, triggered using packet radio (RFM69) and it worked really well. I offloaded the LED animation to a trinket and the soundboard was separate too.
Nice
The Bastion suit had a gun turret with super bright LEDs in the barrel, so when I loast my kid at Halloween, I just fired off the LED's and it was easy to spot him!
Yeah I have an amp and speaker inside for sounds. I just haven't gotten them programmed in yet. And I gotta do stuff with the leds
Hahahaha genius
I need to figure out how to interface the board on my lightsaber and my trinket to trigger at the same time. Which is proving tricky because the trinket always picks up the button press but the saber doesn't. I think that's in the saber's system though. It's just being a butt
Use the trigger on one, and have that fire off the other
If they share a common ground, it works pretty well
That's what I tried. I ran the wire from the button to both the input on the saber board and also to my trinket. Isn't in sync though
use the trinket to capture the button press, then use one of the pins on the trinket as output, and that can fire the sabre board.
You can add a delay in the trinket code if necessary
Or do the reverse
Depends on which is ahead of the other, timing wise
Hmmmm. That's what a friend recommended. Only issue is that the saber's board also detects long and short presses. So holding the button down will make the lights do different things.
Like if the saber is off and I long press to turn it on it will turn but there will be no audio, and vice versa to turn audio back on. And if the saber is on and I long hold the button it will flicker the lights as if 2 sabers are clashing together. So I have to simulate those long and short presses with the output of the trinket
You could make the trinket generate long and short presses
Ok. I've never actually done stuff like this with my arduinos
Thats the inside of my Bastion gun above. Boost1000c, Amp, Trinket Pro for NeoPixels and Trinket RFM69 to talk to the suit
That gun doesn't actually shoot darts anymore either.
Nice
Sadly I can't look at my saber till this afternoon cuz I'm at work.
But I'll definitely look at what you said. I just gotta figure out how to do that hahaha
Work -- me too -- ping me later if you want some suggestions
I would love some help!! I'll pm you real quick now so I don't lose you lol
Howdie do there gang? I have an old but nun the less Sparky moment.
This little fella was bought just as an after thought addition to an order a long while back. Low & behold, this little piece ended up being one of my most used items that I'd ordered from you guys. & man did it get used! This little device did probably hundreds of hours charging LiPo's that were rated, not just in mA, but in Amps. 2 amp, 5 amp etc & it did it's job like a champ! Until one day that little IC in the middle there let off a teeny tiny little puff of smoke. I've sense ordered & received a couple 1000C powerboosts, but I still keep this little guy around. I'd repair it if I could, I really like this little board. 😃 What an awesome little device, superbly designed. #sparky
This one is just a live & learn thing, Never use (or at least don't over tighten it) a ratchet strap to secure a blanket over a chair. Awesome leather desk chair that I put a super comfy soft blanket over. Well, I wanted to make it so that the blanket didn't hang to far back & knock things off of the table behind me. Never occurred to me that the ratchet strap would crush the wood inside the seat back. Lol, Ooopsie.
Using NeoPixel rings, Flora boards and tiny LiPo batteries, I made a pair of Earrings for my lovely better half. Unfortunately, after being stored in a box with other metal jewellery, one of them has given up all the magic blue-smoke :(
#Sparky
Cute! Good thing spaky didn't come out while she was wearing them!
No magical smoke here!!! I did a little solder job on my drone today to replace one of the arms on it
Wip in progress of a Zelda chest for my reddit secret santa
Its using a normally closed reed switch so when the chest is closed the magnet is opening the circuit,which breaks the connection to the battery so its using no power at all
that's awesome @mystic ruin ! cool idea for a secret santa 😄
feeling festive today ^_^ https://youtu.be/zdnWsbYriK4

My wife has been working on a cross stitch for my secret Santa, she hasn't cross stictched in 20 years apparently. If I knew she could do this I would have been getting her to make stuff for me all the time 😂
@mystic ruin Hey! That's fantastic work! Kudos to her!
Just updated my TV-B-Gone: I wanted to slim down the design since the AA batteries seems a bit conspicuous. I've got the system dropped into a mint tin and uses an ipod nano battery now:
@mystic ruin this is great, my gf cross-stitches all the time
I did this a little while ago, but I figured out how to get my wemos d1 mini to talk to firebase.
https://github.com/nishtahir/wemos-firebase
The repository also outlines how to get authentication to work as well.
Also includes a small android app to show values coming from the wemos in real time
@twilit mauve very nice!
Wooooooooo!!! got my lightsaber almost completely done. just gotta add in code for detecting quick button presses to trigger something. but everything else works great now!!!
@mystic ruin thats SO cute i love it. best Link too!
I'll pass the praise on @white zenith !
It's finished now, just needs to be put in a frame
I made a through hole version of the pwm charlieplex matrix board. Time to solder 144 jst sockets lol
Where did you order them @white zenith ?
I was pretty tempted to make an order on that jlpcb site that a few YouTubers have mentioned recently
You can order 10 number 100mm x 100mm boards for $2 delivered which in my book is insane
i made them for a class actually. my professor ordered them through 3pcb way he says theyre pretty good and is going to post to our class bulliten how to order from them
about 20 boards for $5
It's all an elaborate plot to bankrupt us. I don't know how it works.
"Just keep giving them stuff for below-cost, and pretty soon they'll be bankrupt!" [applause erupts] << that's how their meeting went
Cluttered desk = cluttered mind
Empty desk = ? mind
Though, sometimes, the reverb up there in my head is amazing. Should rent it out for choir practice.
I just make sure I maintain a path to my chair and computer!
All I care about is there's another pair of shoes just inside the door I can grab and change into, while still outdoors in this weather. What, did they have a sale on rock salt or something?
Mudroom for the win.
Hehehe in the first pic you can see my giant foot paw for my costume. I wear them around the house because they are built around slippers. And they're comfortable to wear
just admit it, you wear your costume all the time
MXChip IotDevkit the first init
this have next step https://www.instagram.com/p/Bcol_YLAIgK/
@cunning lava kinda sorta actually. at least when im not at work. I have a custom made hoodie that matches the costume and was originally gonna be part of it before I got the massively fluffy bodysuit. And if im not at work im probably wearing that thing
Its great.
Side note to that. Was actually debating on wearing it on show and tell tonight to show off my lightsaber. I mean, I'm no sparkle dog like @obsidian grove but I can glow other ways lol
need to start working what i put for another part so i can use adafruit edgeconnector
@wicked horizon it looks like that
Hey guys, if I want to participate in the Youtube show-and-tell what should I do?
Never mind, I just found the information!
Woooo lightsaber is all back together. now im just waiting for it to charge!!!!
I'm looking forward to the weekly geekout that is showandtell.
I may not make it back in time to be on show and tell. I'm out with the girlfriend
how long until it starts?
Starts at 7:30 Eastern
goes to look for a timezone converter
@cunning lava 25 minutes
thanks
@woven relic Awww.
I may make it, my webcam works with the local viewer, but lets see if it works here.
Sorry @obsidian grove . Maybe we can do next week
Hello all, I'm new to Discord, but I've been learning Arduino for the past year. I thought i would share my latest project. Using a BLE feather, dual relays, and a gyroscope, I built a device for my wheelchair. From an android app, I can tilt and elevate with angular presets. I have a bit more code to write but the hardware works beautifully. Knock on wood
@lime blade sounds great!
Good lord, look at all those icons!
Wooooooooooo!!! I have 400 feet of silicone wire on the way to my house
24awg, 10 different colors
@woven relic I'll bet every connector salesman in the world is lickin their chops. 😃
lol, gotcha... ><>
@woven relic Are you just using T connectors or something else. I recently started converting almost everything I do over to MT60 connectors. Same bullet connectors as the XT60 only three of them. I wish there were something like that with four poles but three works for most of what I need. But between having three poles, having a bit of cable strain relief, being relatively small, and being rated for 60A continuous, they cover most of my needs.
Though rather than four poles rated to 60A, I'd really love something that was two poles rated to 60A and two (or more) rated for data which were smaller, and fit into a similar size connector.
@shut sigil looks like fish
@sudden crane yes they are the T style connectors
It figures... the project I'm working on wasn't ready for Show & Tell last night, and it all comes together today 😃 Next week.
@karmic fjord This just gives you time to work out your Show & Charades skit if your mic is dumb.
