They are open in the bottom and work well. However not great for a light sensor obviously
You’re going to want to put conformal coating on the connectors etc, but not on the sensors. This protects from humidity and some rain.
(I was not using Sparkfun’s kit)
Measuring rain and wind was the hardest thing for me to get right for a solar powered solution as you need to have something monitoring them all the time and can’t sleep it
I went with an external chip to count rain and wind and woke up the microcontroller every 5 minutes to collect and transmit all data
And to be clear, the sensors were in the solar shield but the microcontroller was in a sealed box, conformal coated and with silica packs inside.
Final tip: proper placement of weather instruments means keeping away from roof, walls, and so on which can make the range of Bluetooth problematic. Commercial solutions use other radio frequencies. Adafruit should have something that would work (but I haven’t done that myself)
From the Sparkfun forums Nate (I think the CEO) seems to be the one that wrote up their weather station tutorial they have. Seems like he just oversized the LiPo and let it run and has gotten a few seasons out of it with the solar cell and charger. (Kind of surprising to me) https://learn.sparkfun.com/tutorials/weather-station-wirelessly-connected-to-wunderground/discuss
@feral acorn thx for the info. Do you have a recomendation for brand and application technique for the conformal coating? I have not used that before
I saw there they are thinking of switching to a ESP8266, curious how that works out for them. This was my first solar powered project, most complex one overall, so it was full of learning and I’m not expert for sure.
The coating I used was this one
It is pretty easy to apply, just want to be sure not to cover up sensors. There is a guide on the company’s web site ISTR (MG Chemicals)
If you put the sensors in the type of box they suggested I don’t see how it would be accurate (calibration wouldn’t help).
I should be clear my goal was to have a station that has the gold star from wunderground.com, meaning highly accurate
@feral acorn thx. Ill look at giving it a try
@mystic ruin I don't have a level shifter but I'll add that to my list of things to read about. As @glad roost pointed out, there is a VBATT connector that will output whatever is powering the CP (USB or JST, whichever is higher).
@glad roost I accidentally found out that that if you supply power TO the CP's VBATT pin, it will (at least momentarily) power the CP ... there's nothing stopping it. I forgot how it happened, but it definitely wasn't intentional. Anyhow, of course Adafruit Support warned against doing that again :). Side note; Yesterday I allowed my project to crash (CP NeoPixels freeze bright white-ish) and then checked the voltage on CP's VBATT (just to see what it would read) and it showed 2.7V, the Feather's 3V read about 3.0V. I reset the setup and then checked the levels pre-crash and they were 2.9V (CP) and 3.3V (Feather). I guess that probably just means the voltage drop across the CP increases during a crash, maybe cuz of the NeoPixels lighting-up. Not sure why the Feather, during the CP's crash, also shows about the same voltage drop across it's 3V pin though. Next I want to figure out how to check the current draw for each, just want to think through HOW to do that ... already blew my spare fuse doing it wrong on a different project :).
Does blowing a multimeter's fuse (or two) while trying to learn how to measure current count for #sparky
? It was a noob mistake but also an "ah ha" moment. I'll probably do it again a few more times to be honest.
Not just noobs do it. I think I saw LadyAda recommend keeping a stash of spares
@ionic spade Yeah, that's not just a noob mistake. if it were, then the pro grade multimeters wouldn't have fuses in em, cuz the pros wouldn't need em
APA102 chip on Gemma M0
@feral acorn @umbral fog - lol ... whew, good to know and good advice. I didn't want to wait two whole days for Amazon prime but had a heck of a time finding 750mA fuses locally ... ended-up paying like $2 for 2 at my local Ace Hardware store. No dramatic pictures but in the year I've been tinkering, only killed 1/3 of an RGB (my only common anode...came from Radio Shack) and 2 fuses.
hey folks, don't know if this is the right channel but I have some questions about the astro pi project...
@fallen grail Try the #help-with-projects channel
@calm sparrow thank you, i'll drop by that channel
You're welcome @fallen grail!
From a blown up motor controller to a homemade arduino with the wrong chip and an led Christmas tree with an led soldered the wrong way round shows we all make mistakes #sparky #mistakes message is always use chip socket, make sure your wires are all inserted 100% so they can't touch and to always double check before soldering! #sparky #learning
spent a good half hour trying to figure out why my motor was only getting a trickle of current, but my power supply seemed to be putting out all it had. Can you spot the mistake? Luckily no sparky this time.
Your board is plugged in to wrong end of breadboard?
Good eye lol. It reversed the ground and power rails. I felt so foolish it took so long to catch.
Oh jeez I always forget they aren't symmetrical.
Did some hacky hacking tonight 😃 https://twitter.com/chalkers/status/904571974927564800
Today I learned about packet sniffing with Node.js on Windows and a built a proof of concept! #JavaScriptIoT https://t.co/I271JHN2Hu
Should work on macOS and Linux
@mystic ruin thanks for the help 😄 -- I can finally see under my monitor
also featuring @plucky otter on the display 😛
Anytime!
@mystic ruin using blynk for the first time x)
I've never used it actually, it looks very nice though
I've recommended it to people a few times though
@mystic ruin super easy to use, plan on running my own blynk server for fun to see.. since it costs $ per module ..
For plain toggling between colours something like telegram works well and is free (it suits me though since I use telegram already) but it wouldn't be able to do sliders like blynk can
@mystic ruin the free blynk stuff is actually suitable for most small projects, not sure if the experience is the same if self-hosted
Adafruit IO does sliders well too
not sure if its a bug or what, but using sliders/other input on blynk disconnects my esp8266 and i cant change the modes after..
will try it on adafruit io tomorroh
I was using an Arduino as an automated camera and learned what wire the pin socket things like (hint: not 30 gauge)! #sparky
using another project to test a project.. 😛
progress on the color tool im making.. this one's running on micropython, i want to eventually make it all run on circuitpython but still working on figuring out how to best handle the sensor data..
Diy soldering to fix this led lensing P7 
ok still it show the light but it's always on so switch still dont work
The digital library guide I did made it into this months MagPi magazine for one of 10 pi zero w projects you can make
congrats @rare frigate !
I also found my intercom project mentioned from a tweet I had done. I ended up using the alexa wand though since it was a lot easier than setting a pi up.
@mystic ruin thanks
That was you, Kirby? Awesome!
I made a video on programming an esp8266 (feather huzzah) with the Arduino IDE
https://youtu.be/AFUAMVFzpWw
How to program any ESP8266 development board using the Arduino IDE My Recommended ESP8266 Boards: Wemos D1 Mini Clone* : http://s.click.aliexpress.com/e/uzFU...
I added imgur image uploading to PiGlass, when it uploads I send a push notification to my phone with the link so I can share it via text, email, etc
Nice!
@mystic ruin watching now!
🤗
Made a ESP8266 led control page 😃 not sure what to even call this..
It's probably more aimed for beginners than yourself @cascade
I was going to do it via MQTT etc etc but that seemed more complicated and involved for just controlling lights...
I call if progress!
@mystic ruin I am technically still a beginner ..
Look at you with your nicely styled buttons 😂
@mystic ruin is a web designer
Us mere mortals down here trying to get by with bootstrap 😂
I set up an environment for bootstrap like a week before they launched the new version that isnt backwards compatible ._.
@mystic ruin is very far from a Web designer 😋
@mystic ruin still good video review
Thanks, I wanted to have a point of reference where I can start making videos that people might be interested in making that are not necessarily into making yet
Like a youtube subscriber counter or crypto currency display
@mystic ruin oooh, never dabbled with any crypto currency stuffs
Coinmarketcap.com has a nice api for getting prices of stuff
I made an Arduino library for it
@mystic ruin if i built one .. id have it play audio samples from the price is right 😝
You see a price is right to me isn't the same thing as it is to you
We would have watched the UK one
@mystic ruin oh! X)
@vernal ferry how did you implement the buttons?
Tap tap tap is this thing working?
Yes, @warm sage
@robust fiber was reading a switch on SD2 , @mystic ruin pointed out that I could use the reset button (push twice, using a different library) to invoke the AP config page I have a spare button to do what I wanted the extra button to do xD
two revisions of my flagship project. it's coming along nicely
@vernal ferry Ah when you select the button, does the webpage jump to another page? Currently the implementations I know do that, and it can be a bit annoying to navigate.
@robust fiber nope, made it ajaxy by @mystic ruin 's suggestion
@vernal ferry would you have code on Github I can look at haha
yeah sure, im about to upload an updated version
@robust fiber https://github.com/eighthree/Simple-LED-Strip-Controller/blob/master/ledstrip_controller/ledstrip_controller.ino
Thanks @vernal ferry!
@robust fiber np! I'm expecting to re-use a lot of what I plopped on here for my other projects. LMK if you have any suggestions/etc. 😄
Sure thing
@robust fiber how the buttons look like on the project
also, responsive.. so works mobile phones and such.
aw that's very cool! How long did it take you haha
today.

@mystic ruin really nicely done, and clearly explained on the ESP8266 video
Thanks a lot @terse totem !
So some of you may have seen I was working on a discord bot for a server Im on. Well I finished it and it's running and working well! I have it running on a Raspberry Pi for now as its free but may move it to a vps in the future.
What it does: We have a forums website that we use to keep everyone up to date on stuff we're doing, we found ourselves often posting links on our discord to newly created threads as people are lazy and don't check the website often. So we wanted to automate that! Luckily the forums software was use has an RSS output option so I used that to grab the latest threads (new only) and then parse the data and spit it out in a nicely formatted message to the discord server. My bot checks every 15 mins if there has been a post made and if there has been, then it messsages discord with a link to it.
How it works: I grab the RSS feed every 15 mins (it only contains the most recently made thread), then because the forums software labels the threads in order (i.e. if the last thread was #143 then the next would be #144) and then the bot checks to see if the thread it is analyizing is a newer then the last time it checked; if so then it sends a message with the thread title and link to it. That way it will only ever send a message at least 15 mins apart (to keep the annoyance at a min). And to be honest we only get a few posts a day so even every 15 mins could lengthened. See attached a pic of how the message is formatted! I've blanked out the main url for privacy.
that's pretty cool!
A 2 minute clip from my stream Sunday of the WiFiControlled RC car working
Its a pretty fun and simple project, just need:
- A RC car (I used one with a wired remote, bigger is better as you have more room)
- An ESP8266 board (feather Huzzah or similar)
- A motor driver (that supports two motors)
Code is here:
https://github.com/witnessmenow/WiFiControlledRCCar
It hosts a webpage on the ESP8266 you can connect to with your phone or PC to control the car
@mystic ruin that's slick
thanks @calm sparrow
@robust fiber did you find use for my LED strip example?
Update on my LED controller.. now works with homekit and has a colour picker 😃
Cool, how’d you do the homekit integration?
@feral acorn I use homebridge, which runs on my raspberry pi -- was looking for plugins and found a simple plugin that controls them via HTTP/HTTPS -- so while I was writing the bits to change the colours on the fly through the colour picker, I just had to make the format work with the plugin. 😄
@feral acorn although technically should work with Google assistant implementations that are the same..
ok, was wondering if you’d done the iOS11 route, hoping homekit will be open enough with that release
@feral acorn I didn't want to specifically build around homekit support, its just a nice bonus 😄
I got PiGlass to send and receive texts messages with twilio, I'm gonna see if I can make calls with my mems microphone
Not really electronics, I know, but here is the work table I made from pallets so I would have a space for projects.
nicely made
@proper dirge we call that "maker infrastructure"
@proper dirge really nice sanding and finishing on the top. did you oil/wax it?
Thanks
@terse totem It's a satin poly on the top. It took several coats, but came out nice.
Looks great. I see you've got plenty more pallets ready to be transformed...
lol you should see the stack of broken down pallets inside the shop.
@proper dirge Have you had any experience with wipe-on poly finishes? I have some and have been itching to try it.
@eternal maple that's what's on the top there. I love it. It goes on thinner than what you may be used to, but if you put the time in, it comes out really nice.
@proper dirge Good to know. I'm making some birch ply workshop shelves that'll get the wipe-on treatment. Thanks!
Nice space for making
Awesome table, I can barely assemble stuff from ikea 😂
@proper dirge I would like to work on some pallets, but all I got on hand is sandpaper. Not sure how far I can get with that.
Can't really get very far in woodworking if you are renting
@proper dirge any recommendations on how to start?
Lessened learned, don't leave a PLA printed quadcopter in your car in Florida... #sparky
This ABS 3D printed hand caught on fire during a robot competition. Remember to plug in your 'Balance Charging Socket' when you are fast charging your LiPo batteries... #sparky
Lipos scare me @keen temple
I'm pretty sure that I bought the same charger as you too, but still haven't used it
@rustic stag First time using NeoPixels and WOW THIS IS BRIGHT! (Which I'd consider good)
Oh, I'm still very much a novice, @robust fiber .
Is that the table you shoot your videos on @proper dirge ?
indeed
I thought it was the floor in the first video, then noticed you had a mouse on it in the second video so was bit confused
😃
I converted a ikea desk lamp into a camera mount for my overhead shots. It works really well actually. I'm using two go pro adapters to connect it to the light
great idea @mystic ruin ! :]
Qi charging station. Still figuring out the case for the bottom.
Tapped the charging LED to tell me when it is charging something.
Starts to animate the neopixels when it is doing so. Still adapting the firewalker shoes code for a smooth fading tail animation.
@mystic ruin I flipped the ikea lamp upside down 😄 two uses!
the lamp that keeps on giving @robust fiber !
Indeed @mystic ruin 😉
Yup, awesome lamp. #ProjectEnvy
Doesn't look like I will be able to get twilio phone calls to work with PiGlass😞
But SMS, MMS and faxes work great
@lucid bloom have you find tiny projector for piglass
I'm working on screensharing
I'm going to my local makers Meetup soon they haven't seen me since our last maker faire, so they haven't seen my new smart airsoft gun, PiGlass or my 7bot. Here the old versus new smart airsoft gun

@lucid bloom I watched the SnT listed above. Very nice. Night vision has got to be awesome to use.
@shut sigil yup it's very fun
Spent a bit of time doing this over the last few days, I'm looking to make a how to video on making a simple solder free crypto display using an esp8266
(just for you eagle eyed crypto currency checkers, the $ symbol should be a euro)
@mystic ruin You wrote that in Circuit Python right? 
I can't be purple just yet @calm sparrow
I do really want to try it but I have such a backlog of stuff I want/need to do I'm just not sure when I'll get to it!
@mystic ruin I hear ya there.
Yeah it's funny, I released a library for coinmarketcap.com api, so the sketch for the above project is actually really straightforward
I'm probably not going to be the person writing low level drivers for new displays etc, but very happy to try make somethings I can do easier for others
For anyone interested in it
@mystic ruin Any help is much appreciated. Thanks for posting your code!
It's one of the things I like about the maker stuff, is how open it is
Cool @mystic ruin ! Will look at those when I start using displays with my ESP boards 😄

I was about to say "oh tell matt his piglass has competition" and then I looked at who said it 😃
@lucid bloom Sort of like my Google Glass where you could blink and it would recognize it. I need to find a use for those things.
Yea the wink to take pictures, no one really developed any eye tracking apps for it
I know, it bombed. But I still have mine. My great great grandchild will sell them to Mike and Frank for a couple of bucks. 😃

I finished up (well at least stuff works 😃 ) my summer irrigation project that uses Feather m0 RFM69's, Feather Huzzah, Adafruit.io to automate watering of my backyard based on moisture sensing...in case anyone is interested -> https://bitknitting.wordpress.com/2017/09/12/summer-project-automatic-irrigation/
I'm very interested! Thanks for the link!
@cedar root you should demo it on the show and tell stream too!
@rustic stag all good. just wanted to play along. 
@lapis jasper on demoing - when I watch the show and tell these amazing projects that blink or show images are shown...can you imagine watching water dripping? I have to face reality - auto irrigation doesn't show well...although it totally improves eating well. I've had a terrific growing season. A bit touch and go with bird competition particularly for the blueberries and strawberries. Blue Jays are brutal. Seriously. I would not want to be a finch in a garden that has a blue jay patrolling it.
the gear that makes it auto water is interesting!
@cedar root I definitly would be interested in it!
@cedar root Agreed, I was even telling people about it today.
@glad roost @umbral fog I got my toaster oven for use as reflow and finally satiated my desire to see inside: https://imgur.com/gallery/btLq7
its two boards and I'm hopeful I can design a new control board for it
@cedar root just talking about it, and the code you used, etc would be very interesting!
@lapis jasper now that’s a real unboxing
@lapis jasper We got ours a couple of days ago and really like it as a toaster, especially the "A Bit More" button. Is there any readable printing on the microcontroller chip?
@lapis jasper F0411. Maybe this: http://www.futureelectronics.com/en/technologies/semiconductors/microcontrollers/8-bit/Pages/9031250-UPD78F0411GA-GAM-AX.aspx
do you see a description of markings?
I was thinking it'd be fun to try and dump the code off of the chip 😃
new album link: https://imgur.com/a/5GCnK
I just Googled the larger number (no luck) and then the smaller one. One hit had TQFP in it, and that helped narrow it down. There are some other F0411 chips that are quite different. I was wondering if you could reprogram it and not have to redo anything about the oven at all. Just bring out some JTAG or SWD wires...
yeah, I was tempted. I really want it to run circuitpython though 😃
I also cut the ribbon cable so I'd need to redo that at least
I appreciated that you put the screws on the metric side
I generally prefer mm
I did some work tonight on the crypto display, I tried out using string literals to program a Web page for the esp8266
Worked great other than the ssl WiFi client was crashing if the Web server was runnin
I had all this nice Web page stuff done, and just had to take it out again!
The sketch as is will crash when it makes a request, but I'm pretty happy with the string literal stuff, pretty sure I'll use that again. Might make a decent reference for people too
@plain stream @lapis jasper @scenic siren @mystic ruin @prime widget I want to thank you all for your kind comments and support of my auto irrigation project...if you scroll backwards on the posts from here: https://bitknitting.wordpress.com/2017/09/12/summer-project-automatic-irrigation/ i tried my go at documenting the project as I learned stuff. it goes through challenges i had w/ the hardware - like using standard irrigation valves - sharing 24 v w/ 3.5v....power management...

@lapis jasper since the flash ate em: what're the markings on what I'm assuming is the actualy MCU?
nevermind.. apparently it was a case of phone screen eating it....
@cedar root have you been on show and tell with this yet? because if not you absolutely need to
this is awesome
that isn't your adafruit io key though, is it?
I made a bracket set to support my camera rig 😃
@ogredrew I spent a while last night tracing all of the traces and trying to determine pin funcitonality. Still not done yet though
This one definitely let out the blue smoke, giving it a test drive the day before the competition and the Mosfet went bang! Didn't really need that late night of soldering. Then the new one went bang,. If you didn't fix your short, it isn't fixed! #sparky
@clever pebble that's very cool, and seriously old school!
yeah it is and funny thing is that there is tissue paper between wood and circuit

#sparky 
Welp.
Happened just now.. The lipo connectors were reverse.... :<
Where could i look up that part and would I still be able to use the board if I replace this part?
Worth a shot
board still works..
Yeah definitely worth a go so
wouldnt trust it connected to my computer though in case... it ppooofs
im not sure.. its part of the battery circuit..
i cant find that part. not sure what to search, its KDCV
What board is it?
It's probably boost or maybe cut off voltage detection, I guess they would be first inline for a battery
Pinout matches this
And that's the battery circuit of a feather
Go adafruit for being open source hardware 👍
its a wemos esp32 board
looks like this is the part! is there a way to find a better version of it?
if im ordering some edit: ordered! x)
omg @bitter minnow your pumpkins are amaaaaaaazing!

You can get them as a module that isn't too big (I think)

ive posted my twilio code on github, there are 4 programs. Two will work on any pi and the other 2 will only work with other programs on PiGlass. SMS.py and readSMS.py are the two that will work by themselves
https://gist.github.com/matt-desmarais/b7076f6393d8be48260399eefeeb50cf#file-sms-py
https://gist.github.com/matt-desmarais/b7076f6393d8be48260399eefeeb50cf#file-readsms-py
Here is the rundown of the programs
SMS.py prompts for a phone number then a message, then displays them to you and asks if you want to send it.
readSMS.py reads the last 10 text messages and numbers them, then asks you if you want to reply to a message, if you do you pick the number of the message then type your reply. then displays it to you and asks if you want to send it
newMessagePushNotification.py sends push notifications to my phone when a new text is recieved, with the number and message content
textLinks.py will ask for a phone number and that last x number of pictures taken that you want to send as links.
I don't work with ATTINY85 development boards often, but when I do I always make the mistake of killing the Zener diode between the USB power and ground (by shorting it). Mostly because when I use them on breadboards, I forget that the power pins are all in a row. Oops. This is a board from one of my projects, where I decided to double down on the sketchiness by simply brushing away the charred remains of the diode and using a jumper. Luckily, this board will never be used in a USB port again so it's unlike to kill a USB port anytime soon but I've made a habit of reminding myself not to do this! #show-and-tell #sparky
@terse totem , you asked on the show about a somebody with a physical challenge trying, asking for advice on how to solder.
I know is not the same thing, but I have used Z-Axis tape to do arduino like boards on paper, but the normal use is for prototypes or small repairs.
You just cut a little square of the tape, peel it, stick it on top of the PCB without solder paste or anything, and then just put the chip or led or resistor on top of it.
Hope it works....
Oh and Adafruit does have it in the products 😃
@crimson egret @terse totem There are commercial one-handed soldering irons with solder feeders, though they're expensive: e.g., http://www.hakko.com/english/products/hakko_fx8803.html
@glad roost I've seen non Hakko branded similar ones
One of the grocery stores near me have different special items every week and one week it was one of these
for like E20 or something
(that seems ot be coming from china though)
You could also use solder paste and hot air.
@crimson egret @terse totem @mystic ruin @rustic stag Ha - now I remember there was a forum thread about one-handed soldering: https://forums.adafruit.com/viewtopic.php?f=44&t=88001
@vestal jasper what dive computer do you have? Is this idea adaptable?
Well, after more hours than I care to mention, my interface is starting to look like something that may eventually grow up to be usable. Eventually the picture there will be from a live camera, and the panel on the right will have sensor data (distances, compass direction, etc). I still need to add status lights to the blank spot below the photo, and once the camera is set up, add in the camera controls.
For now this will be interacting with a huzzah breakout using Circuit Python through the webrepl
Very impressive @proper dirge! You've out so much time into this, it'll be really rewarding when you're done. It already looks great though!
You should share this to the CircuitPython channel too. This has to be if not THE first, one of the first projects like this and how you're using socket to send stuff to the webrepl. Certainly is the first for CircuitPython, not sure about micropython
Thanks, @calm sparrow I'm hoping to get a lot of it done this weekend. I should be able to get most of it done assuming there's no major hiccups. It's been interesting, that's for sure. I'll post more in the #circuitpython-dev channel when I get a bit further.
Making things look nice is just not in my wheelhouse
@proper dirge is that made with what?
@clever pebble The gui is HTML/CSS. It's using websockets and javascript to connect to, and communicate with, the webrepl Circuit Python client running on the ESP
@proper dirge functional > pretty
fuctional can be pretty as well @calm sparrow
finally got the second prototype of my colour tool finished 😃 now for the software side ...
@vernal ferry Nice!
@scenic siren ty ty! I'm hoping to eventually port it over to circuitpython ;3
@vernal ferry is that for detecting color?
@proper dirge yeah 😃
got some smartphone lens adaptors and using a wide angle/fisheye
case is modular so i can swap out aperture sizes and or lenses infront of it
i thought adding a polarizing layer between the sensor and subject would help but it reduced sensitivity a lot
Oh cool. I used to color calibration of monitors at a large photo lab. It's amazing how far things have come.
@vernal ferry That's cool!

Haha, looking good @vernal ferry!
I got my weekend project of a circuit python driven rc car at the level of completeness I'd hoped at this stage. The car itself is runnng a circuit python script. I am using a web page on my computer and communicating with the webrepl through websocks to send calls to that script, and parse the return values. This seemed like the logical route. Why build an interpreter for my project when one is already there?
The web page I'm using to control it really needs some love. Itis not pretty, but it is working, and that's the important part.

Very nice project Brad. Do you plan a write up on how you got to this point?
Great job @proper dirge! It's awesome 
Thanks!
@feral acorn I hadn't thought about that, but I don't see why I couldn't. I'll just need to find/set up a place to host it.
I'd find it useful
@proper dirge Instructables just launced a motor competition!
you could write it up there and enter it
I made some progress on the my remote camera trigger device
https://gfycat.com/HeavenlyDearestFritillarybutterfly
Cause I love punishing myself I stated out with a HC-06 bluetooth module and flashed firmware onto to that is HID compatible
@mystic ruin That's really neat!
The HC-06 is on the white breadboard and there is an ESP8266 on the small one, when the footswitch is pressed in sends a "Volume up" command, which triggers the camera
Thanks @scenic siren
It works really well, but I would suggest if people want to make it they should get the Bluefruit Ez-key as that seems to support HID out of the box
oh ..."Note: This product is currently undergoing a revision and will be available again soon!"
@mystic ruin That is really cool. How does it trigger the camera? Is there something attached to the phone?
I used anHC-06 (or was it 05?), a while back with a leonardo to act as a keyboard for sending macros. I feel your pain. To say the documentation on those is lacking is putting it nicely.
Oh, do you have a link for that contest?
It's connected as a Bluetooth device to the phone, so it's acting as a keyboard
Volume up on a keyboard or headphones triggers the camera
oh, ok, so it is sending via bluetooth straight to the phone. That's pretty cool. Nice job
You were sending commands to leaondro that was acting as a keyboard was it?
We like to move it move it, you like to move it move it, let’s all move it, move it for the Make it Move Contest! Your project can move on its own or by your power. Make it fly, run, glide, skip, wiggle, roll, or propel, no matter what you make, all you need to do is make it move! Get it in gear to win a PivotPi Starter Kit, EmpathyBot Kit, or Raspberry Pi 3 from Dexter Industries! Incorporate motors into your project for a chance at the judges’ prize! Don’t let your projects be stagnant. It’s time to get up and move!

I got the idea from a youtuber called Evan Kale, he flashed one of those modules with hid firmware for a project
He has a good video on it, but he uses a parallel port
To flash the module
I haven't had a PC with one of those in about 10 years at least!

Is what I used to flash it with an ftdi chip
I think I'll try make a video on it this week
I'd recommend checking some of evans other videos out too, I think they are really good
He strikes a good balance of showing you really good and interesting stuff and being enthusiastic and entertaining with it
@vernal ferry i guy I worked with was just asking about building something for detecting when his laundry was done, do you have more info on the project?
I want to make a logo for PiGlass and I'm trying to think of a new feature to add, if anyone has any suggestions let me know
@lucid bloom Does it have GPS?
Okay, I think that could be a cool feature, but I don't know
I'll definitely give it a try walking directions would be cool
Oh yeah!
@lucid bloom Also, about the logo, I could do one, it shouldn't take too long, but I'll have to do it when I get back
Not a problem
I have an appointment first, but I'll try to get to it!
Thank you very much
No problem!
@mystic ruin Yeah its actually an example code for my led strip project
@mystic ruin there are a few ways to approach it, I went the audio route
@mystic ruin the other examples ive seen measures the power draw of the washer/dryer unit, others use piezo
hi @vernal ferry you won a #sparky pin! Please email sparky@adafruit.com. Congrats!
😀
Didn't understand the difference between negative ground and positive ground when using LM7912 instead of LM7812. Not a mistake I'll make again! #sparky
@potent jolt looks like a good one to tag with #sparky
@bright hull Thank you! Fixed.
The regulator still works, actually. Took me a while to figure out exactly what happened, but the cracked case is damage caused by the electrolytic cap that blew right next to it. As you can imagine, it made more like a flash than just a spark, and a loud pop like a firecracker. Was glad I always wear my safety glasses.
also. nice photo! 👍
Same incident as above. Melted the plastic around a couple of points on the breadboard.
I started doing electronics projects in high school 35 years ago. Somehow it look until a year ago to learn that ground can be positive. I was following the datasheet from TI for the LM7912 and where it said I should connect to ground I connected to negative. I knew it didn't look right, but I connected the power after I wired it like I thought the datasheet indicated.
I've made a lot of mistakes over the years, and damaged a few components. Usually it was carelessness or misunderstanding a procedure. This stands out for me as the time the components decided to teach me a lesson.
@brisk pond aw yeah! ty ty! I shall! 
@mystic ruin thanks to your suggestion about using that ws2812b library 😄 -- 2.0 of my desk light will have.. pleeeeenty of light effects to work with.. just gotta make it look/work better 😃
Hot diggity dang
@lucid bloom Hopefully this is close to what you were looking for? If not, how should I change it?
Oh, whoops I used my other account @lucid bloom but @indigo patio is me!
Looks awesome @vernal ferry!
Wohooooo! So many Sparky

@mystic ruin 😃 I’m excited to work on the interface when I get home later. For some reason after x period of time the ESP crashes 😦
Dang
There is a command Esp.getfreeheap() or something
I'd wager that you eventually are running out of heap memory or something
Another thing is some people say they work better if you put a cap on the power rail of the esp8266
Never noticed
@mystic ruin will look into that thank you! What size cap? Using a wemos d1 (the uno formfactor)
I'm gonna try and demo some PiGlass features that no one got to try at the maker faire because I was having bandwidth issues with my 4g hotspot
CAD explosion!
@vernal ferry
Joy bonnet explosion
I can never watch show and tell live. I'm normally teaching a class at that time.
So in advance, thanks everybody for your cool projects. This show is something I haven't missed since the last 3 years or something like that.
Enjoy the show later guys, I was hoping to show the Bluetooth remote camera trigger but I'm too tired! 😴
@mystic ruin Rest up!
Yes! My exam finished 5 minutes ago so I can join Show and Tell!

A prototype of my ESP8266 LED strip controller v2 control panel 😄
very nice @vernal ferry. Is that a page running on the ESP8266?
@proper dirge yup! v1 was heavy, v2 offloads a lot on client side
what are you using to program the ESP?
arduino rn
Awesome. It looks really good.
@proper dirge thanks! I'll be posting updates as i go, I expect it to be more fully fleshed out once i get the other parts working 😄 lmk if you want to try it out once i get it to a usable state
Yeah @vernal ferry , I certainly would. I've been using mostly Circuit Python lately on one of my ESP boards, but I always like to see new stuff. You can literally offload everything to the client using the webrepl interface in CP
@proper dirge I could totally make a CP version of this but wont have the same featureset
no?
using a bunch of libraries to do the light animations and wifi manager for ap and such
could still make a CP version tbh, would just be simpler
ahhhhh...gotcha
would be fun to try porting it though!
I look forward to seeing it progress. It looks like a really cool project
If you're interested, here's a small sample project I put together in CP communicating via websockets. https://github.com/notthatbrad/Circuit-Python-Web-Interface
yeah...well, allegedly. We'll see how far it gets
Good example btw, does the index file live outside of the esp?
Thanks. Yeah. It stays on your computer or wherever as long as it's on the same network as the ESP
Oh wow. That would be cool.
Is that what you're going to do with the lightstrip controller?
Nah, its going to be mainly be a web-interface so i an access it on my phone or tablet
but can see it being useful on another project
@vernal ferry And when I saw that Electron post I immediately thought of the RocketLabs Electron booster.... 🚀

No. Space elevator is a silly idea with current materials (do the physics). This is the SpaceX BFR and the lunar/Mars colonies.
Ooooh, thanks @vernal ferry - that looks like a cool link!!!!
😄 #space
Or, as Elon has said, "because who doesn't love rockets?" 😉
@prime widget about to watch the first ep of Startrek Discovery x)
its all connected xD
I haven't seen it yet!!! I should watch that between Elon's speech and Formula 1 Free Practice 2.
I mean I really really want to go to space
but at this point lunar colonies, or even economically feasible space trips, seem past my lifetime
I think getting cargo to Mars is quite feasible. But I think the health issues for humans in transit and living on Mars is much trickier and the solution isn’t clear at this stage.
@plain stream spacenation org can be one way to make it
I'm not saying it won't happen, just that there are lots of steps to get there, and with my current age, life expectancy and income whatever's possible before I die won't be able to include me
I really hope I'm wrong, though!
in 2024 to mars
in 2222 to the moon.... again
Hacked the HUZZAH-based weather station to show battery status. Needed a hardware mod on the TFT FeatherWing to scale and route the battery voltage signal to the ESP8266's 0-1v analog input pin. #MakerFun
I made this Midi to arduino speaker/buzzer conveter program and this is my arduino playing the Super mario theme, its a Small project that i did https://www.youtube.com/watch?v=c8xESa9-bZ8
Soooo i got a 16$ kit and made this You can ask me if you want to know how easy it is to put music on a Arduino
a Speaker will sound better
i also tryed every daftpunk song and most of them work really well
I need a new one of those power boards for a breadboard. Mine got messed up. Though I do have a voltage stepper that I can adjust from like 3v you 55v or something like that and it puts out 2-3amps
Also getting a teensy audio board and a few more hall effect sensors on Monday!! Gotta quickly learn how to trigger and play audio files in an attempt to rush my project in time for show and tell. Worst case is it won't be done In time and I show it off either incomplete or wait almost 2 weeks to show it complete.
HAve you guys seen this im thinking of getting a few of them, you can also use it as a rubber ducky
sorry
here is a image of it
there only 1$ each
😃
but 30 to 50 day shiping
BUT Shipping is FREE
@gleaming belfry the HID is implemented using v-usb which is not true USB hence it's not very stable for USB rubber ducky type applications.
i know its space is not sutible ether but it can do its job
Wooooo paint!!! 😸
https://www.thingiverse.com/thing:2562449 I designed and printed a mini dreamcast!
This is a small Dreamcast measuring only 100mm x 100mm x 36mm. It's super cute as a desk toy for your cubicle or looks adorable right next to your full sized Dreamcast in your game collection! I tried to make it detailed as possible and also accurate as possible to challenge how well I can model things, and I'm happy how it came out.
what about mini C64
Oh that's an awesome idea, I'm definitely adding that to the to do list.
https://twitter.com/sparrows89/status/901029902476029952 I actually designed this too, and it's going to fit a raspberry Pi and a small mechanical keyboard I have
Hopefully that’ll end up being a harness for fiber optics... 😃
(Side note: I wish the soldering and assembly portions of these projects came as easily as the programming... )
and another side note... why is it, no matter HOW hard I try... I always get superglue on my fingers? Every... Stinking... Time...
@thorny bluff: I switched to gel-type superglue for just that reason. It happens less often now...
I have Gorilla brand hot glue :3 it's gorilla glue in hot glue form. Works pretty well sometimes!!!
I find that using a nail polish brush works pretty well. You can buy a cheap brand and clean the brush with acetone, which is pretty common if you do 3d printing.
Oh that's a great idea!!!
It’s not the best picture, but the harness lights the strands, so I’m taking it. Lol
That looks cool!!!
Started this project 2 years ago, finally finished it just in time for my daughter and GeekGirlCon.
Hmmm. Not sure why there's no preview?
Thats pretty cool!

@spice dust was so great to meet you and your family at Geek Girl Con, and see that awesome portal gun in person! Great work!
Thanks, @eager pine--good to meet you too! My daughter had a great time and wants to go back next year. Thanks for letting me know about the event!
@spice dust oh awesome! glad to hear it! plenty of time to make her next costume hee hee 😃
@eager pine Don't let my wife hear that! She's probably already dreading it!
apologies to your wife @spice dust i am definitely a costume enabler
As you should be, @eager pine!
really though, I love the portal gun you made - i would have no idea it was made of soda bottles!
you should show it on show & tell!
Yeah, I was thinking about that. What's the process?
I don't know if it counts as a fail for the purposes of the contest, since the build part went well and even came out nice-ish looking... but I just realized that I did not properly understand the physics of the wingsails I am building and therefore picked the wrong airfoil. As a result, they're very sluggish to respond to control inputs... to the point where control on the water is fatally compromised. DOH.
@spice dust on wednesday before show & tell starts, they post about it on the google+ page, comment on that post that you'd like to join, and they'll invite you
@spice dust here's a link to how to do it: https://learn.adafruit.com/how-to-get-added-to-the-adafruit-google-plus-show-and-tell-circle/about-show-and-tell
I have a #sparky story that dates back 2 years, to when I first built the portal gun: https://forums.adafruit.com/viewtopic.php?f=19&t=83571&p=423091#p423091 After blowing the amp, Adafruit returned my money (yay!) but pulled the board from stock while they checked out what happened (kudos, but 😦 ) and it took a while for me to find the Teensy Proto Shield as an alternative. I didn't have any luck with that one, though, so I took another stab with the Feather M0 Express and outboard amp.
@fickle otter hello! how goes your sail-bot?
Thanks, @eager pine, I'll take a look
@fickle otter at least you know what an airfoil is 😉
We were in the water on Sunday... and while it did sail and we were able to steer it, it was not really controllable, because the wings responded sluggishly.
An airfoil is just a thing that produces lift when you push it through the air... like an airplane wing, or our sails (or any sail, really).
Yeah... we're going to put in more of the electronics and give them bigger tails before we go out again.
https://www.ladonproject.com/blog/ has a nice pic of it in the water. I wrote my name and phone # on the sails to assist recovery if we lost it, and all of the photos we took managed to have that side of the sails. The pic here has had that crudely edited out.
😃
You can only really tell b/c my cheesy editing managed to cross the shadow of one sail on the other.
nice! looks legit sea-worthy!
That it is!
While launching it, I dropped it from about 18" up and the hull went all the way under before popping up. There's a small leak in one compartment, but it leaked no more than a couple of teaspoons of water in an hour, so I am not too worried.
nice! what body of water are you testing in?
Greenlake
It's protected, near a weather station... and there's a boat rental place in case we need to go fetch it.
smart
it can't go too far away in Greenlake!
@fickle otter great to hear your boat's coming along! bedtime for me, talk to you later!
Hey, that's my neighborhood!
Gonna do a little PRE-SHOW AND TELL show and telling. @junior dust @wicked horizon this is the same thing I showed you two last week. It's in my hands now and I'm excited to get things moving in it!!! Basic lights are done, I'll be adding more backend code for the lights later and a paint job will happen this weekend. The 3d printed section is actually in 4 parts and I need to bond them together somehow (any ideas would be nice, it's PETG) there is another section that I will need to work on that is on the reverse side of the gun. But it will come in a bit
@woven relic the light diffusion looks really good!
@junior dust Thank you! once i throw in more varried light modes it goes a little meh but still looks cool! Might just be something i have to play around with for what does and doesnt look good.
on a side note would you have any recommendation for bonding all of the sections of this together?
sure I tend to use E6000 because works well with flexible stuff but takes a while to fully set
Thank you. might try some of my gorilla hot glue for temp to hold it together till im done and then do E6000 once im ready for it to be more permanently stuck together!
@fickle otter try adding trip strips
@bright hull The stuff I've read on them doesn't mention any effect on pitching moment... Do you have a reference that does?
not off hand. what airfoil section are you using?
ok. i got 45 minutes to get a hall effect sensor installed in this thing before show and tell
Good luck, last time I was going to share I was in the same boat.
May the force be with you
may the force be with you!
Tonight I am ready to share my project that I built with a Trinket MO that I won the first time I went on Discord.
@woven relic suggest lots of ventilation for E6000 - so great for sticking things together but very fumey. At work we let it vent in our spray booth until it’s completely dry 👍
yay @visual canopy
Looking forward to it @visual canopy !
Thank you for your help with it @lapis jasper !
no problem @visual canopy
I have no idea but my hall sensors are no longer working...
Where do I find the link to the google hangout?
someone usually posts it here
oh
phil post soon i think
ok
i hope i killed all the bugs in my code
good luck
@lucid bloom There are always, ALWAYS more bugs
My personal theory of development: don't bother trying to kill all the bugs, cuz they'll just breed new ones. Just worry about corraling them off so they're easy to deal with when they happen
Where is the link
Or, as they did with Linux to start with: When in doubt, PANIC!

@uncut meadow relax. here it is: https://hangouts.google.com/hangouts/_/wbdf22e5rvbvfalem3dgyvideae
That is a rad controller @wicked horizon
The eyes have it...
Nice Blade Runner reference there, @marsh quest !
Does it display Celsius also?
@visual canopy looks really good!
Huh. Musta messed up with Hangouts--I didn't make the cut!
me niether it happens
I think I must not have clicked through accepting terms in time, or something. Maybe next week!
thats the attitude!
@quick mortar , it is measuring in Celcius, but displays as Fahrenheit since that is what they use in schools and on TV here in the states
@lucid bloom did you get bug fixed
Yeah, I was one of the first 10 comments so I was looking for an invite. But I might not have been fully active yet. It's ok--just wondering about the process!
@spice dust you never got a call on hangouts? next week I can hook you up with the link. just ask me for it
I've watched on youtube before but not Hangouts, so I had to accept terms on Hangouts and I think I must not have active if someone was trying to invite me.
ah, ok
I got an e-mail and clicked on it, but there were a few prompts to get through.
it does have you confirm that you are ok being on a live stream
Yup. I stepped away to see if my daughter wanted to join after I thought I was in but came back to a prompt.
oops! I can help next week if you need it
Nah, I think I know the process now. All good!
cool cool!
@clever pebble this what I see on the vufine and the 2nd is the text sent to my teammates those are all simulated gps coordinates
The bugs I was having were opencv related
@bright hull Wortmann FX L V-152
It has a decent max Cl for a symmetrical foil and the Cm is both small and monotonic
based on what data?
airfoiltools.com has polars for a huge variety of airfoils
mehhhh i looked at my portion of show and charades, the lights didnt show as well as i had hoped..
@fickle otter did you make sure to compare data at same reynolds number?
Yup... I used the 100k Re for comparison, n=5
My problem was a bit upstream of that... I assumed that a low Cm would be best. This was not correct... and my tails are too small.
hmmm. yeah. i was eyeballing ~60k based on your photo.
pretty low
the tails are those t shaped things coming off the trailing edge? what are they for?
Setting the angle of attack of the wings
The wings are free to rotate
Chord is 250mm, so Re=100k is a bit on the optimistic side.
5 m/s is what I've been mostly using, so about right on the speed.
i bet trips would generally help out. but i can see those tails being the bigger (smaller) issue.
The design goals are a bit different than airplane wings... for example, on most points of sale total force (drag + lift) is more important than getting the best L/D ratio.
yeah. so don't worry about adding trips. it'll help L and will also increase D.
a simple diagnostic would be to do some tuft viz on the lifting surface
Yeah, I think the next time we're going to have good wind + crew availability is either Sunday or Monday
I'll hot glue on some tell-tales before that... as well as enlarging the tails and adding a bunch of onboard data acquisition.
GPS, hull orientation, sail orientation, tail position, and relative wind direction.
My first cut at a windvane failed b/c the skate bearing's drag was excessive, especially with the magnet in... so I ordered a replacement windvane pot from Digikey.
Super low drag, but $17.60 for a pot is pretty spendy
ideally you want the sails free floating / rotating? but need pot for orientation. but it's got sticktion.
No, the pot is for the windvane... it's the recommended replacement part for a well recommended vane/anenometer set that's pretty widely recommended.
Sail orientation is from a compass mounted in each one.
Just the mount for the initial try... I found out it wasn't going to fly before that test so I left it off.
white patch on front of orange hull?
Nope, black object on top of the right-hand wing.
Tacking 😃
I can back out the relative wind for the boat because I know how the sail is oriented relative to the boat and magnetic norrth.
yep
So I wasn't at show and tell today, but boy do I have something to show.
Looks cool @bitter valley
Yep! After work tomorrow (today technically) I'm going to be coming back to add another layer of plaster if it needs it, and then hopefully do a pour of hydrocal.
@bitter valley keep posting pics! I'm excited to see how it turns out.
Definitely. I also want to eventually do a video series when I get my costume parts finally made.
Like my cosplay page and it will keep you up to date on most everything I'm up to on the costuming front.
https://www.facebook.com/High-Vibes-Cosplay-467861040280536/ posted pictures of the finished mould as well as a "First timer" postmortem.
@bitter valley I like the wide angle shot of you just... hanging out 😃
Haha. Yeah, my friends have a good eye.
@bitter valley nice!!! Very brave 😃 now you can make all kinds of head things!
That's the plan!
Woohoooo! Got the attiny set up to control the speed of the motors on my roverbot using the encoder discs. Now I can put one on each wheel and use analog values to tell it what speed to go.
Woooooooo!!!! getting closer!!!!!!!
if you go to the link its an actual video
my project REALLY blows
@woven relic sounds like it! 😜 looking good!
How is it going to blow air into your suit? It’ll be attached inside somehow?
Hehehe sanku @eager pine !!! still gotta do a lot to it. Im gonna end up using epoxy putty on the outside of the shell and then dremmeling at more of the plastic inside until i can fully fit my lipo inside it.
and it wont actually be hooked up to my suit. this will be a prop blaster i can carry around and share coolness with others. I actually have one of these fan units broken down and have a part of it installed inside the head of my suit. and its hooked into a usb battery pack along with an adjustable voltage stepper. i adjust it anywhere between 5v and 12v depending on where im gonna be suiting. though its something that has to be done BEFORE ever putting the bodysuit on.
Oh I see! How awesome to build a prop that does something nice for other people!
I love the pulsing light section
thank you @eager pine ! I have it programmed to do all sorts of other light patterns too. i just didnt show them in the last video. Here is a video of the modes i have so far: https://photos.app.goo.gl/rbFRxaiem7Ch9rIs2
a handful of those are actually just the examples from the fastLED library. i gotta come up with something of my own too.
Also, my original version of the nerf fan thingy was a box made out of legos that only had 2 fans in it, EVERYBODY loved it, for both the creativity behind it and the fact that it usually cooled them down!
Oooh, cool glowy things!
ITS. SO. DERPY!!!
When I die, I want this exact bust to be on my family's memorial.
That is an impressive piece of work
The nose is a bit crooked, the mouth is... stretched? And the alginate shrunk and became embedded between the layers on the left side.
But all things considered, it's useable!!
It's functional!
(Especially since I'm reasonably certain that if I tried that my tiny little bit of claustrophobia would make me freak out)
THE MEASUREMENT CHECKS OUT! IT'S USEABLE!
Awesome!
@bitter valley Great job!
Grats @bitter valley !
Many thanks to the “celebration spectacles” tutorial and the fine folks in #help-with-projects
@thorny bluff That looks great! Nice job!
looks interesting
@thorny bluff hey awesome! Did you sort out that Gemma or switch to the other one that was working?
@eager pine yes / no. I think we chalked it up to a non-write protected boot loader that got written to.
I think this is the most wires that I have used to breadboard a single project.
Oh my.
I am getting back into OpenCV! Next is to get it on a Raspberry Pi.
Good to see you @keen temple ! Its been a while sinc eyou've been on Show and Tell!
@woven relic I guess it is a racing drone, but I am not that good at flying it yet. I plan to make it more autonomous. @lapis jasper I would like to go for the drone badge by flying it on the show and tell soon. Are there any Adafruit microcontrollers specifically for drones yet?
@keen temple nope. I did some drone stuff before adafruit though. most flight controllers use stm32
@lapis jasper Well, I'll leave it up to you to design one for Adafruit. I will try to get openCV on a Raspberry Pi 3B next.
@keen temple my first one didnt go well. I doubt I'll make another
Boom!!! First nerf gun with a usb port
Do I have enough wires in such a confined space??
@woven relic A.B.K. - Always Be Knolling.
not entirely sure what that means. but ok!
you can look up the wiki but essentially a saying to keep everything neat and organized, in this case wirewrap, bundle and route wires cleanly to save you headaches later in troubleshooting, modding or maintenance. Get that tube of a zillion assorted nylon tie-wraps, handy for things like this.
what did you use for the light diffuser panel? is it an original part or 3D printed?
its a 3d printed part. my buddy modeled and printed it for me
@woven relic Your Nerf gun is starting to look like my SEM.
lol yeah really!!!
From experience, that is not necessarily a good thing...
ok good. most of my wires are bundled together in some way/shape/form
@woven relic Cool. Depending on the look of the lights, I like to diffuse neopixels under a rigid bezel even more with additional polyester fiberfill or that stuff from an air conditioner filter.
oh it looks great under this thing! i have 2 strips inside with 16 neopixels each
protip - if you need to take pictures or vid of your rig, do a strip.setBrightness(10); to set really low brightness on neopixels so they don't blind the camera. It's tough to capture the beauty of neopixels or LEDs in action.
ohhhhhhhhh!!!! thank you!!!!
im actually using fastLED but its pretty much the same thing
when programming though it would actually help a lot if i plugged the thing in though...
I've found the info and examples here inspired me to create some Fastled project. https://www.tweaking4all.com/hardware/arduino/adruino-led-strip-effects/#library
the embedded vids there don't work for me in chrome but seem to work in other browsers
huh
The Fastled example page with the embedded videos don't play for me when using Chrome browser, may work for others or it's just the system setup I have.
I have been messing around with a Bluetooth HID module and a capactive touch sensor, I now basically have a Bluetooth Makey Makey board
I'd like to add some more features, but the basic, touch a pin and that pin sends a keyboard event is working
@mystic ruin Nice!
@mystic ruin @quasi vault has been asking about bluetooth hid
oh cool
@quasi vault Im using a HC-06 flashed with RN-42 firmware, working pretty well so far!
@mystic ruin could you post a schematic? I have a few ideas i want to try with it!
Sure @cunning quest
Video on how to flash the firmware here
https://www.youtube.com/watch?v=y8PcNbAA6AQ
But it might be easier to just buy a RN-42 😃
Flash HID firmware on to a $3 Bluetooth devices so you make it act like a Bluetooth keyboard/mouse or game pad! Unlike other methods for doing this, this met...
Adafruit's Bluefruit is due a revision i think, but currently they dont have one available (afaik)
For the touch part im using this
But adafruit have a 12 key module that should work the same
Wiring is simple, BT module connected to software serial running on two GPIO pins on my ESP8266 (D6 and D5 on my Wemos D1 mini)
Cap touch sensor connected to D2 - > SDA and D1 -> SCL
Code here, but it needs work!
@mystic ruin Hi Brian, this person turned on the bat-signal, it may something to put your work to good use. https://forums.adafruit.com/viewtopic.php?f=8&t=124724
The RN-42 should work if im reading it right, but i dunno is it cool to be recomending non adafruit stuff on their forums?
Replied there @leaden frost
@mystic ruin Thanks. Sharing is Caring. That's how it's supposed to work.
for sure
An old work firend got on to me there last week, the charity he works for was looking for someone to build them an arduino device for measuring water for one of their service users. It's a pretty straight forward project and I said I'd be happy to help out
It kind of really made me think that there is probably tonnes of problems we as makers could solve for people
The Atmakers.org site sounds amazing
Seems to be US only though
I'm one of those general use makers who also dabbles in electronics, various stuff on instructables but yeah, there is a lot of things we can do as community service. I'm proud to have done this for my kid's class in the 6th grade and later for a high school https://www.instructables.com/id/Rehearsal-Cubes-for-acting/
That high school saw the instructable 9 years later and asked me to help out.
ha
hi @cunning token ! you won a #sparky pin! Please email sparky@adafruit.com. Congrats!
hi all, I finally completed a small milestone towards turning my bookshelf into playable snake (and maybe eventually playable tetris) but so far i have a 3x10 grid that I can control like this:
I used #neopixels and an #arduino on my bookshelf. I'm eventually going to further segment it to turn it into playable snake. #adafruit https://t.co/fqUuSVoPUz
nice! looks really fast.
Yeah I threw together some code that I found online
the rainbow is actually from test code that adafruit provides for neopixels
@ionic spire Very cool! You should show it off on show and tell tomorrow! I might have to do this in my shop sometime...
@plucky otter thanks! I was thinking about that
@ionic spire that's very cool
@spring elm thanks!
great job @ionic spire
@lapis jasper thank you!
@ionic spire That's really neat! Nicely done.
@scenic siren thanks 😃 Took me all summer
@ionic spire Worth it!
yeah now that it works xD
@ionic spire how do you dectect touch? Capacitive touch sensor?
detect touch? It doesn't do that
...how will snake be 'played'
ooh
or will just be an animation?
i'm not there yet, I have to change everything around
I just wanted to test the wiring and see how to control each shelf
I'm actually going to take a break from this project for a while now that it works and come back to it later
but I know some guy made playable tetris, I was following his guide
and he used a raspberry pi and plugged in a PS3 controller in one of the USB slots
@ionic spire awesome!
Here is a little project I knocked up so that I can display stuff on a small display attached to my Raspberry Pi. SDL2 on the RPi tartgets X11 and so needs to be rebuilt if you're after it working in the console. So here is my simple solution. 😃 https://github.com/HamAndEggs/FrameBuffer
Not going to be able to be on S&T tonight so here’s my progress so far
It’s the control box for my Super Dinosaur costume (the joysticks are for the tiny T. rex arms to control the robot [ie my] arms)
Everything but the Ethernet jack is from Adafruit, including the box (which had Adabox 005 in it!)
Going to use cat 5 cable as an easy way to transfer power, ground and two data lines to machinery mounted on each shoulder (laser and Gatling gun)
neat. it seems to have a personality. four eyes. two antenna.
what data are you running over the cat 5?
Neopixels. And speakers, hopefully, but I have to figure that out.
tested it yet? how long is the cable run?
could work. definitely give it a try.
@plain stream if cat5 doesn't work, try cat6, it is a bit heavier gauge.
then cat7
And then, if that doesn't work... Just go find an actual cat.
Cat5 cable works great for all projects. Best thing is the wires are paired up to use as a double run and they are color coded. Still haven't put a dent in the 1000' plenum grade spool I got as surplus cheap.
well if you want more performance oyu can get Cat6
I don't think there is any appreciable difference when working with neopixels and power. Kinda like when the big box stores try to upsell their HDMI cables.
@woven relic I know I'm a bit late to the party, but your work is fantastic! So when you mention suit are you talking about a fur suit?
Hehe thank you @small nexus. And yes I do mean fursuit
@woven relic Nice! Attending any conventions any time soon?
I'll be at FangCon next week. And then after that no fur cons until Furry Weekend Atlanta in April
FangCon? Sounds like it bites
not gonna make it tonight, unforseen setback
Dang, won't be at any of those
Need to hit up Furry Weekend Atlanta. One of the best ones out there
Would anyone be able to take the show and tell sticker and turn it into a stencil for spray paint? Or at least digitally edit it to print it off and cut a particular way to use as a stencil?
Progress! Using the cast of my head and successfully made my first pattern with it. Miles ahead of what I was able to make with my old duct tape head dummy.
The main helmet I will use for the fiberglass mould will be made of floor mat foam, but for the face mask, I may use craft foam with sandwich board as support struts. The eye holes are intentionally smaller than what they will be because I'm going to carve out an area for the paintball mask lens from the foam helmet after I make it.
The eyes were only open so that I know exactly where my eyes are in the helmet.
I ALREADY MADE THAT PUN TO MY GIRLFRIEND! Beatcha to it. ;P
Hah!
@bitter valley awesome! whenever I make helmet-type-thingy-patterns based on my actual head size, i have to scale them up or they are too small. the thickness of the final material vs the paper pattern ends up making a big dfference. do you usually scale up a bit from the pattern?
@woven relic I don't know if you are familiar with it, but there's a Telegram group for DIY makers that has A LOT of fursuit related stuff. It's called "The WIP Zone"
It was created by the furry artist Matrices, who has many tutorials on fursuit making
@coral gull I know of the group but I'm not in it. I also don't do work on fursuits unless im looking to do something specifically to my own.
I see. I don't really make fursuits myself, but I find the craftsmanship behind them astounding
I understand. Im in a fursuits group for electric fursuits. Very nerdy
@eager pine Basing the mould off of a floor mat foam build of the helmet will give me a final piece scaled up by 1/2"
Artyfakes is doing this week Wonder Woman gear from foam (had to correct)
Nice! I need my stuff to be a bit more durable though, which is why I'm taking the extra step of moulding and fiberglassing.
@bitter valley Nice! Can’t wait to see it 👍
But no, you guys, if you get some helpers who have even a remote clue what they're doing, alginate moulding is not that hard. I have no idea how I got by without this thing before.
And then mixing and pouring hydrocal is pretty easy as well.
#sparky I put the button on backwards!
http://electronics.onebeartoe.org/battery-chargers/powerboost-500/
This is for the PowerBoost Charger enclosure I showed yesterday.
@clever pebble Yes, and it is a pain in the ass.
@bitter valley totally as you can hurt yourself or someone who do that could accidentally when cut it hit to skin and make wound
Guys guys guys guys!!!! He did a thing!!! And he used a nano!!!! https://youtu.be/FILJznSr6fs
The SR-1 Semi-Automatic Portable Railgun is a field augmented circular bore plasma armature railgun capable of firing 6x19mm conductive armatures as well as ...
@woven relic He did a thing AGAIN. He's already made a 3D printed railgun before.
Yeah but this is his newest one!!! The video was posted in the last 24ish hours.
That guy is insane and quite talented.
Hey, I have a little tip for the people who might wanna do the Show-and-Tell, but either don't have a webcam or want better video quality. There's an app called DroidCam that allows you to use your Android Phone's camera as a webcam, via either USB or WiFi. It also allows you to use the phone's mic if you want.
You also need the DroidCam software on your computer, and it's pretty straight forward to use. The program makes the camera detectable as a webcam, so you can use it with streaming softwares, video chat, etc
Oooh!!! I've never heard of that one Blackcorvo!!! Thanks for that!! It could be helpful at one point
I discovered it when looking up ways to film myself playing Cuphead on a keyboard (which I have yet to do, but the setup is pretty much ready).
Ah cool
Just gitchu a newer xbox one controller. They got bt and you can also just plug it In and it works
I'd rather use a USB controller if I were to use one, but in this case it's supposed to be a challenge
besides, I'm more used to using the keyboard rather than a controller, and they're usually expensive here in Brazil anyways
So this project is still a work in progress, but I thought I might share what I have so far. The lighting is two neopixel rgbw rings running of an adafruit Gemma m0.
Sort of a triple #sparky here. I got an Uno so was finally able to fix the bootloader on a Trinket I had screwed up months ago. While working with a cheap RGB LED strip I forgot to use PWM pins for blue and green. When I desoldered and soldered to the correct pins, the other PWM pin I had been using somehow had its pad disconnected from the board.
Doing this stuff at midnight isn't always the best idea. 😃
@woven relic I knew the day would come when a rail gun like this would be feasable. It's the power that was always the limiting factor. I worked in a Magnetic Components department for 20 years and we often talked about building a rail rifle. Many sketches, but backpack batteries was just not practical. The semi-auto aspect is the other impressive part. Very nice mechanisms and I beleive I heard them mention 3D printing. Thanks for the video. 😃
https://m.facebook.com/story.php?story_fbid=473181453081828&id=467861040280536 - I has a cosplay page now. Need to remember to share that instead. :P
I are doing a paint!!!
@woven relic oh cool
The blue is soooooo pretty!!!!
It blue you away?
Yes

Nice @slim sierra!
hi @normal zealot ! you won a #sparky pin! Please email sparky@adafruit.com. Congrats!
@brisk pond Awesome, thank you 😃
@normal zealot Add some tomato sauce and some meatballs, problem solved, right?
Well I took the rest of the tape off the gun.
theres a handful of minor mistakes and goof ups.... But im not gonna bother fixing them till after the con. might redo a couple parts afterwards. otherwise it looks pretty good
Friendly reminder to post your #sparky moments with a picture in the #show-and-tell channel for a chance to win a
pin!
That moment when your project is finally coming together!!!!!!
welp.... everything was going GREAT. I had everything working so i closed up the project and when i screwed it shut i plugged it in to test and my ubec converter fried!!!!!! and i dont exactly have time to get a new one before i leave for my convention tomorrow....
#Sparky
@woven relic Where is your convention? There might be a Fry's or Microcenter on the way or nearby
