@steady fox Works fine. Sounds fine. Not my genre but....

[steady fox]

What genre?

So when i stop it does it stop on your end?

[heavy siren]

Led Zepplin, what else? 😮

[heavy siren]

Thank you very much Mr. @steady fox

[steady fox]

Hmm i wonder if this is too subversive for the kids today?

lol

[heavy siren]

Absolutely NOT! 😃

I raised my kids on Led.

[steady fox]

hahaha

ok here is another attempt.

/play [https://www.youtube.com/watch?v=HQmmM_qwG4k&list=PLjH4YJfu1WfE2bciiQZ7Ci0TiIDzYE3HJ]

that is a zepplin play list ....

lol

and guess what it starts with ... just epic.

[heavy siren]

My wife just told me to turn it down.
If it's too loud, your to old.
GAWD I love that music.

[steady fox]

hahaha

stir it up.

[heavy siren]

I wanna jump on my drums right NOW!

[steady fox]

awesome.

do it.

[heavy siren]

It's 9:30 pm and the wife ain't gonna go for that one bit.

[steady fox]

don't forget to grab a old mostly empty bottle of rye and splash it on like you been drinking all night .... hahaha.

before you start that is.

[heavy siren]

But when the cats away, you can believe the mouse is at play.

[steady fox]

yeah my neighbour just banged on the ceiling. hahaha.

[heavy siren]

Bummer, Have own house on acre. Vol;ume at 11 doesn't matter.

[steady fox]

Yeah in a condo it does.

[heavy siren]

I know, been there, done that. Some day tho, you'll have your own place.

[steady fox]

no kids live above or below or either side.

[heavy siren]

That helps.

[steady fox]

Have a couple of places already.

this and three others.

[heavy siren]

Ah, ok, well, rock on... ><>

[steady fox]

with injuries cant take care of any of them they are all rented out.

here you go rock list.

[heavy siren]

Listeing to it as we type. Thanks eh? For me, these are memories. And many are backseat ones. If ya know what I mean? 😃

Link saved

[steady fox]

Yeah 😉 i am sure we do.

[heavy siren]

LOL

[steady fox]

I wonder what the younger folks like to listen to these days?

[heavy siren]

Oh, lots of good stuff, Twenty One Pilots are pretty good. My daughter turned me on to them. Bill likes the heavy rock but John likes the old stuff like Rush and Pink Floyd.

There is an Australian band called Ice Jupiter Groove that like alot.

[steady fox]

Yeah just checked in spotify what my daughter and neices are listening to.

mostly rap stuff.

at this time.

so since its halloween have to go watch a netflix movie.

kind of a tradition these days.

Have a great night everyone.

See Ya M8te

[heavy siren]

Have you heard of "The Lights Out" from Boston?

@everyone hi folks!

Today's coupon code UVMASK gets you 10% off your order!

This week’s tutorial: UV Curable Solder Mask LIVE https://www.youtube.com/adafruit/live

[shell mason]

oh yeah you guys are still in summertime

[severe inlet]

Technically, copper doesn't rust (since rust is iron oxide). Copper does corrode or oxidize though, obviously.

[river peak]

Mars rusts though

[shell mason]

any way to make PCB to space proof?

[dire bane]

remilling after would be a bad idea. the mask is there to be solder repellant - esp. important on smd boards

[severe inlet]

I wonder if you could use a uv sensor and integrate the signal to calibrate the light source to determine how long you need to irradiate the pcb.

[harsh bone]

I'm way too lazy to do any of this... 😉

[shell mason]

i was thinking as you can 3D print cubesats structure so the PCB in them to cover them for space weather

[harsh bone]

Rather just use a service...

Bring them with you to a tanning salon..

[dire bane]

there are iron-on sheets you can use as silk-screen - you use a laser printer on the sheet then use an iron to apply the silk-screen layer

the toner is the adhesive

[eager sapphire]

And toner adheres tightly, so UV doesn’t bleed under the mask

That is clever

[shell mason]

think maker cubesats

this cubesat was 3Dprinted http://www.goodnewsfinland.com/reaktor-sends-javascript-into-orbit/

[boreal holly]

@open girder Industries If filament absorbs too much moisture, it gets difficult, if not impossible to print with. I get that. But does it affect the processed (heated) filament as far as strength?

[shell mason]

@rocky reef have you found flat connector like those HDMI ones?

[rocky reef]

@shell mason flat usb connectors?

[dire bane]

I think he means usb connectors joined with a flat ribbon cable

something like this but with usb connectors

[hard hollow]

@shell mason ah yep, I'd try searching aliexpress and see if there's a manufacturer. If you find some, please link and we'll take look for potential stocking 😃

I think Limor sourced the HDMI ones from the taobao website

[shell mason]

@hard hollow I was thinking if you can use same usb holes but have Pi zero in the backplate so if there is bend ones for USB

[rocky reef]

ah yea, we sourced from here: https://item.taobao.com/item.htm?id=543545012531

[hard hollow]

@shell mason ah for the boombox?

[shell mason]

@hard hollow yeah

as speakers in the eyes so might get flat design perhaps

[hard hollow]

@shell mason hmm maybe but the speaker boxes may still get in the way of the boards. I'll play around with the placement and see how much space we get 😃

[shell mason]

as speaker bonnet with flat design could make it more flat

[hard hollow]

@shell mason yea and the headers can get pretty tall, even with the PICO hat solder directly to the GPIO https://www.instagram.com/p/BawgiUYH3Sk/?taken-by=ecken

[shell mason]

@hard hollow when you make them level it could able to make GPIO headers flatter?

like that tripler for feathers

[hard hollow]

@shell mason yeah i can get it flatter. just ditch the female headers and seat them flush. removing female headers are easier said than done tho

@shell mason yeah something like the pi hat hacker maybe https://www.adafruit.com/product/3182

[shell mason]

that could help

Let's be honest. If you let your copper oxidize, eventually it'll get to be the typical soldermask green

[pearl shoal]

Love the #failart

[clear matrix]

@analog acorn Hey!

[waxen thistle]

To err is human, to fail you need a computer (or so a bumper sticker told me in the early 2000s).

[split gazelle]

Really awesome to see the whole process on how to work with the soldermask. They also came out really nice!

[waxen thistle]

[river peak]

@haughty quiver You must have really been shocked when that happened.

Ooooh! That thing is cool!

@haughty quiver Thank you very much, there's actually one about 8 minutes away from me!

[haughty quiver]

super, should be 40% off of about $5 ; )

[clear matrix]

@haughty quiver If I remember correctly, using mineral oil will keep the glitter suspended for much longer. It's also messier if you want to keep changing it up.

[waxen thistle]

Oh $5 is a very fair base price

[haughty quiver]

@clear matrix yes! I added glycerin, but not sure yet what the best proportion is

[rapid hornet]

yay @brazen grove !

[clear matrix]

@haughty quiver Glycerin! I thinks that's what I was thinking of!

Either that or both work.

[lavish patrol]

I believe calcium chloride works well as a water thickener.

[clear matrix]

@brazen grove Looks great!

[haughty quiver]

Glycerin is great, I've used it for food safe hydraulic fluid before in a coffee tamper project, and it make the best base for fake blood ; )

[clear matrix]

Bruce Campbell wouldn't agree. I think they used buckets and buckets of corn syrup.

[rapid hornet]

https://www.tindie.com/products/deshipu/pewpew-lite-featherwing/

[haughty quiver]

@clear matrix haha, OK, I should say "one of the better, not too messy bases for fake blood" ; )

[muted mesa]

"food safe hydraulic fluid"...not often you hear those words together. is glycerin == corn syrup?

[inner spade]

@haughty quiver would love to see a snow globe with a miniature magnetic stirrer. No shaking needed.

@pearl shoal Export implies computer... This thing currently has no computer on it...

I can point a camera at the screen though, and capture images that way.

[river peak]

@glossy glacier What sort of signal does the screen take?

Might be able to rig up a splitter or something that leads to a capture card

[glossy glacier]

@river peak I have a digital interface for this SEM, I am missing the computer interface card right now though.

Once I get that though...

[river peak]

Is that something that's easily acquirable?

the SEM is so cool

[river peak]

And is it even compatible with modern hardware?

Adam, if you get it working 100% is there any danger they'll ask for it back?

I assume they killed it and upgraded - but it's still and awsome piece of kit

@gaunt plume EL-wire lifejacket, with high-voltage glory 😄

[glossy glacier]

@river peak It will be a windows XP computer...

stick a screwdriver across the power supply and blow a fuse... "oh no! it's broken... maybe I can stick it in the van?"

[brazen grove]

@gaunt plume and an extra toaster strapped to the back

[gaunt plume]

@brazen grove considering I row thru the winter, it'll be a VERY cold hi-voltage glory

[brazen grove]

at least you don't have to worry about drowning

[river peak]

@glossy glacier Your hardware looks a little older than WinXP, surprised it works with something that new

[gaunt plume]

@brazen grove i'd like to avoid "high voltage glory" (totally going to use that phrase for now on) if possible

[glossy glacier]

@willow pollen One of them has a damaged 120,000V power supply that is currently down, so that's fun. I think I found the cap that took it out though.

[willow pollen]

nice

adafruit hand out blue sparky pins for that 😃

[low fractal]

I think they're ulexite crystals. AKA "TV rock."

[glossy glacier]

@river peak It's a 4PI SEM interface if you want to look it up. I have the SEM interface and cables, but I dont have the PCIe card yet. This things is from the 1970-80s, the interface is an aftermarket thing. I think I might have a source on a card though.

@harsh bone I2C on esp is in software

I thought that there were dedicated pins but that the I2C was software bitbanged, so it only goes to 100KHz.

[harsh bone]

Why I come here 😉

[fallen rivet]

it's definitely not obvious!

[rapid hornet]

@fallen rivet they are probably just designated pins to standardize on

[fallen rivet]

or just lazily hardcoded, or maybe they have special drive characteristics

like open-drain outputs, dunno.

[rapid hornet]

in circuitpython we have our own bitbang code for it

What kind of device would I need to deep fry corn dogs via solar power

[wanton dome]

oh man, that seesaw demo is HOT

[mint harness]

now I'm wondering where they sourced those displays...

[harsh bone]

So, does this thing depend on HW I2C?... Is the Bit-Banged / SW interface too slow?

[fallen rivet]

Q: Does/can the SeeSaw send interrupts, or would another GPIO need to be carved out for that and software support added?

[rapid hornet]

@harsh bone it probably doesn't. it would just be less responsive

[bleak wigeon]

Q: Could the seesaw be used for/as canbus to i2c interface for automotive projects?

[fallen rivet]

The SeeSaw would just be like any other I2C slave and use its HW I2C for that, no?

[rapid hornet]

@bleak wigeon I don't think the SAMD line has CAN support

[fallen rivet]

Might even be able to get it to be a I2C mux

[mint harness]

you'd have to "bit bang" CAN.

[fallen rivet]

CANs in the D51.

isn't it?

[brazen grove]

there are dedicated CAN chips, that also do the voltage adjustment

[fallen rivet]

yeah, the PHY part

[rapid hornet]

@fallen rivet I don't remember

@muted mesa Fall back is super annoying when you're working at the time the clocks are supposed to go back

A year or so back I had a giant donut order of doom so I was supposed to be in at 2:00 AM, so I just went to my boss and said "Just make it 1:45 and then there's no possible confusion in the system"

[haughty quiver]

someone mentioned using an H-bridge so we can do it in software

@ocean musk had that idea, too , IIRC

or was it @inner spade

yes, that was it

[heavy siren]

This is great stuff. That pump can be used for aquarium water levels, plant water distribution. Oh the ideas...

[dire bane]

it's the same style of pump they use on dialysis machines and IV pumps in the hospitals

[eager sapphire]

Yes, that pump, a float sensor, and a source of distilled water to top off evap

[heavy siren]

@eager sapphire That's exactly what I was thinking.

[eager sapphire]

Still trust float sensors over the metallic ones - those get coated or corroded or both and one wrong reading the wrong direction and yikes

[dire bane]

the metalic ones cause electrolysis

[heavy siren]

The only thing John is the 12 volts. Where does that come from?

[haughty quiver]

ah, regulated power supply

[heavy siren]

Oh, I see, an external unit.

[haughty quiver]

I didn't show the supply, it is what I plugged into the 3.5mm female screw terminal breakout jack

yes

[heavy siren]

Do you know what the current draw on the 12 volts is by any chance?

[dire bane]

you know, you could get a pair of those pc water cooling kits and put a peltier between the two waterblocks and make yourself an airconditoner for your desk

[haughty quiver]

current draw is around 3A for the cooler I think

@dire bane yes!

[heavy siren]

Wooo, that's a lot of electrons...

[haughty quiver]

yes, loads of them!

[dire bane]

it's the electrons that pump the heat

a pc power supply is more than enough to power it

[haughty quiver]

yes, that would do it nicely

[heavy siren]

Bingo!!! I found one. https://www.vellemanusa.com/products/view/?id=350599

Get an old Wall Wart from a big HP printer that will supply the power and walla.

I've used Velleman Power Supply Kits a lot. Normaly the 1 amp version. They work great!

[dire bane]

whoops, @heavy siren "input voltage: 9 to 30V AC (depending on the desired output voltage)"

[heavy siren]

Radio Shack used to sell them at a decent price. I scarffed them all up cheap when they went belly-up.

[dire bane]

@heavy siren you can buy a pc powersupply for the same price but will supply more amps and have all the protections

[heavy siren]

@dire bane Right! You plug in a brick with say 24V @ 1500ma or some such thing and adjust the trimmer for 12 volts out. I like to put a pot in for the trimmer and bring it out to be able to adjust it on the fly.

You can use AC or DC for the input. Full Wave Rectified. oops. My bad. This one doesn't.

[dire bane]

the one you show also doesnt have it's own fan or enclosure

[heavy siren]

They made to put into a project.

[eager sapphire]

Speaking of which, bugs me to realize all of the PCs I’ve sent off for recycling without pulling a single power supply from one.

[heavy siren]

I have all my old PC's. Even the one from 1982 serial 352.

[dire bane]

I've pulled many fans from failed pc powersupplies

[eager sapphire]

Pulled the drives, have a nice platter and magnet collection. Bunch of fans. Not one supply. DOH!

Since I’m already a pack rat when it comes to electronics, this is surprising.

I still have my old TRS-80. Way too nostalgic to let that one go.

If ever there is a badge for going off-topic, it should have a picture of me on it.

Hey, shows over, what the heck, a little power supply talk never hurt anyone, right?

@haughty quiver Too cool!

[haughty quiver]

well done.

(that's like having Tea and No Tea at the same time, for all you Infocom Hitchhiker's Guide text adventure fans.)

[eager sapphire]

Speaking long ago, as we were, of water level sensors - came across a simple / clever design for a capacitive level sensor. Electronic, yes, but the metals are not exposed to water; as water depth increases, capacitance between two insulated plates increases (approx 200pF/inch). Easy enough to measure this on an Arduino, and use various level values to trigger fill/drain.

(The 200pF/inch rating was close to a typical value for the relatively simple designs seen on YouTube - the actual scale for pF/in depends on the size and spacing of the plates and dielectric coefficient of the liquid being measured, as you’d expect)

[void widget]

@haughty quiver In 1986 or so roommate and I wrote a Z-machine "decompiler" because certain branching elements in the HHGttG game were too obscure. I distinctly remember a key element being "feed sandwich to dog" early in the game in order to not ultimately fail the game many hours later. 😉

[haughty quiver]

Yes! @void widget this was a plot element in the book, too. That dog would avoid eating the entire Vogon fleet (which was tiny) if it had the sandwich or something like that.

[void widget]

It is not explicitly in the book: that was the whole problme 😉

[haughty quiver]

oh, i see!

[void widget]

they mention the dog and the fleet, but nothing about a sandwich 😉

[haughty quiver]

so you and your roommate were able to decompile it from the floppy disk and solve that puzzle?

[void widget]

yes, we wrote the decomplier in Z80 assembly language on a CP/M machine

[simple granite]

@void widget That brings back memories of my old TRS-80 Color Computer that I had a Z80 cartridge for 😃

[void widget]

@haughty quiver This was the Z80 computer, http://www.retrotechnology.com/restore/ampro_bd1.jpg

[haughty quiver]

ooooh, nice!

[void widget]

I'll have to open that old machine and show the RAMdisk we made for it in 1985

it would bank-switch 16K chunks of RAM in from an additional 128K

[haughty quiver]

Oh wow, Wikipedia just told me that Pac-Man arcade games used a Z80 as the CPU.

[void widget]

yeah, I had a pacman logic board at one time

it was a but tricky to rig to display on a TV

~bit

as it had analog RGB and separate sync for a real monitor

the pacman board had a curious code descrambler daughter board on it, I guess game companies had a habit of dissassembling each others code

so the ROMs were not straight object code, but some hashed data

[odd stream]

@haughty quiver As I recall, Z80 was quite popular in arcade games of the time.

[sweet kernel]

I built a set of runway lights and loaded it onto my feather. Than I tested it out in the back yard and airplanes thought my back yard was a runway, in which they could land. Is there a way to change the sequence of the lights so it doesn't look like a run way.

[burnt wasp]

What kind of runway lights? Meatball on an aircraft carrier?

[sweet kernel]

I'm not sure I made my model with standard breadboard size leds. Apparently when the fog sets in, it magnifies the mini version so it looks like a life size airport really don't know. Something about how the light hits the fog.

So I need a sensor to shut off the lights period if there is any fog at all.

[burnt wasp]

Fog or smoke will diffuse lights and spread out lights like a searchlight in the clouds.

[sweet kernel]

I live near the top of a mountain where there is a lot of fog

[burnt wasp]

Ok, what is your setup, a feather board controlling a bunch of regular leds...and placed along your driveway?

[sweet kernel]

Right. There is no runway in my driveway. In fact there is nothing there. When a plane lands it should land in the airport, than the lights should continue to guide passengers to my stores where they can quickly spend all of there money and go home.

So the lights are essentially dynamic way finding singage that change based on whatever plane someone came in on

than when there is fog you cannot tell who came in on what plane.

[burnt wasp]

You might want to look into marketing methods in systems like Adsense to target specific demographics, in your case determining what the appropriate signage is for the people that come to visit.

[sweet kernel]

No I just need a sensor that can detect when there is too much fog to see the sign.

Not sure which one would do the job

[river peak]

A humidity sensor combined with a basic light sensor would probably do the trick

[sweet kernel]

I've been building websites 15 years I know what to put onto the sign. But what happens when they cannot see the sign or take a wrong turn

Ya but say the sign is 200 yards away. Where do I put the sensors

I guess I could point a laser at a photo resistor from 200 yards but what if a bird or bug came across the front of the sensor

I could give each person a radio, and set up a series of beacons but that wouldn't work because I don't have the money for each person to have a radio.

Infarerd don't do very good in the fog. It looks like its snowing in the infrared dimension.

Therefore, you get a whiteout if you use infared in fog

I need to get a heavy duty fog machine and run some tests I guess. There is something about the refraction of light in the fog that seems like, it could be possible to use it to project a completely alternate reality.

[sweet kernel]

This looks interesting but I know if I read it I will spend the next 5 months learning everything there is to know about fog, which I wasn't trying to do just hoping for a quick solution

http://www.opticalsensors.se/ofs.html

[muted mesa]

@sweet kernel How accurate are weather services with fog conditions? accuweather and wunderground have API that you can use. Basically, a branch off of the "smart mirror" projects....

How accurate for your LOCAL fog conditions, is what I meant.

[sweet kernel]

Ya those services won't be able to provide the needed information. I need to be able to automatically tell if there is fog, and relay it to my system the very instant that the sign is not visible. It only takes a split second for someone to drive into a whiteout. In fog and I suppose a similar effect occurs in the snow, but maybe solving the fog problem will also solve the snow problem. . Currently, there needs to be 24/7 supervision of fog conditions.

Imagine driving down the interstate at 80 MPH, than within a split second visibility is zero and you cannot see the road in front of you.

I learned how to drive in these conditions, but people who come in from out of town. Never seen fog or snow before drive right into it without heeding the warnings.

[strange mantle]

@sweet kernel maybe you could use the metars report for the local airport? https://aviationweather.gov/metar?gis=off
could either use the visiblity part, look for FG for fog, etc.

[shell mason]

@strange mantle nice and thanks for the aviation weather

[analog acorn]

Yep, definitely bookmarked that link, @strange mantle

[peak bloom]

@sweet kernel could you use a humidity sensor? Combined with other forecast data, it seems like that could predict fog with at least some accuracy.

Snow, on the other hand, would not be detected with that

Looking online, it appears that if the current temperature is within 4F (2.5C), of the dew point, fog forms. Combine that with humidity/light/wind sensors, and you may be able to pretty reliably detect fog, or at the very least heavily overcast/rainy conditions.

Hi all, I don't know if this is the right place to drop my question (Mike advice me to look here), but has someone managed a working connection with an ethernet module (for example the WIZ820io) in combination with MicroPython/CircuitPython (for example the Feather Huzzah/Feather M0 Express)? For my project I need to set up a telnet connection <> Uart Tx/Rx. The physical connection isn't the problemen, but it's my lack of driver experience (if any exists).
With kind regards, Jeroen

Greetings, earthlings!

[pearl shoal]

Sorry I can't join you all tonight, I'm in LA @ the ASHA convention. But I'd love to show the device we're rescuing from the scrap-yard next week 😃 Micah (@scanlime) & I have done a teardown & we've gotten the mfg to open source the drivers 😃

[open girder]

@everyone SHOW AND TELL is LIVE NOW #show-and-tell - https://youtu.be/uvxJAvL7r8o

[devout knoll]

What should I do discord and Youtube dont work together ! 😞

[severe inlet]

Chris is back. I was worried since he hadn't been on for a while.

[clear matrix]

@devout knoll Can you download the Discord app?

[devout knoll]

@clear matrix No I mean in Android

[frail flame]

3D Hangouts show is too early for my sleepy self 😃

[pearl shoal]

Chris is doing great - he live streamed the hockey game the other day 😉

[devout knoll]

Wait I have two Phones....

[willow pollen]

needs defender 😃

[pearl shoal]

JP said AT! Yay! 😉

BTW, @haughty quiver I could use a recommendation for escape room in LA (you are in LA, right?)

[haughty quiver]

i'm so bad at Defender @willow pollen

!!

[waxen thistle]

@haughty quiver I saw that you have a tripod ipad stand on your workbench (right next to your arduoboy project & logitech camera) -- That looks so cool! I might have a use for something like that...

[willow pollen]

lol

we all are

[haughty quiver]

ha

[willow pollen]

but the sounds are so satisfying

[eager sapphire]

Pretty good at space invaders tho

[devout knoll]

Wait we have @haughty quiver and @hard hollow and @rocky reef also !

In show and tell 😍

[rapid hornet]

yup yup and @brazen grove

[haughty quiver]

I went to a really good one, @pearl shoal just need to remember the name, standby.

[pearl shoal]

For the record Chris is saving himself thousands by making this stuff himself

[haughty quiver]

this one, downtown was a lot of fun. we did a zombie one: https://roomescapeadventures.com/ @pearl shoal

[cold bay]

Always love watching chris's work

[rapid hornet]

me too

[willow pollen]

chris sounds a lot healthier than last time i saw him 😃

[river peak]

@pearl shoal Money is one thing, but... Just think of the TIME too

[devout knoll]

Why does Chris Talk like a Cyborg ?

[pliant surge]

Chris is such a good presenter.

[ruby ether]

He IS a cyborg, or pretty close.

[rapid hornet]

always well preparared

[cold bay]

@pearl shoal thanks for putting this in both chats. it's really cool and isn't brought up enough

[ocean musk]

ABP always be publishing

[devout knoll]

He is a Cyborg ?

[inner spade]

@lethal lagoon Sophy's cat striks again

[rapid hornet]

[river peak]

Hi @odd stream !

[open girder]

😃 @ocean musk

[pearl shoal]

Chris has Spinal Muscular Atrophy (Type II). His voice in particular is impacted by having a tracheotomy

[simple granite]

Only if Ginsu knives though, @open girder

[severe inlet]

@lethal lagoon , Always blaming the 🐱

[haughty quiver]

cool round board!

[clear matrix]

@odd stream Nice!

[lethal lagoon]

Doh! My FaceTime was on 🤣

[river peak]

@odd stream Your project is rather... jarring

[rapid hornet]

😃

[lethal lagoon]

Though she is right next to me...

[pearl shoal]

Thanks,, @haughty quiver

[haughty quiver]

it's mewing

[simple granite]

i may need to grab the round pcb board idea for my project lol

[river peak]

@lethal lagoon Just blame the cat. She did it once, so now it's always her.

[haughty quiver]

@pearl shoal I can send you some other LA suggestions.

[pearl shoal]

I'm staying at 9th & Olive until Sunday if that helps 😃

[haughty quiver]

If you like odd things, check out the Museum of Jurassic Technologies, which is in Culver City, a bit of a hike.

[rapid hornet]

looking at MIDI

[shell mason]

midi circuitpython

[pearl shoal]

Cool, I will check that out

[haughty quiver]

these rule!

[inner spade]

Very cool devices!

[rapid hornet]

this is @devout talon

[ocean musk]

kinda sounds like the grove or qwiic system

[haughty quiver]

"Being a software guy..." shows a bazillion awesome hardware projects @devout talon

[brazen grove]

I think I saw that on hackaday.io

https://hackaday.io/project/20470-makernet

[devout knoll]

@brazen grove Yeah !

[willow pollen]

i count five stickers

but i may have missed a few

[haughty quiver]

@waxen thistle it's really helpful! The tripod mount frame is from B&H Photo, the tripod is an old one from Polaroid :) I use it for chat during my livestreams, evernote, and more and more documentation

@devout talon great stuff!!

[lethal lagoon]

omg i am a total disgrace lol

[willow pollen]

lol

[rapid hornet]

I blame MIDI @lethal lagoon

[willow pollen]

i thought third time would be the charm

[lethal lagoon]

so sorry to waste time like that

[eager sapphire]

We all know it was the cat’s fault @lethal lagoon

[lethal lagoon]

yeahi have no idea what the issue is now...

[waxen thistle]

I am looking for something very similar, when I do streaming and project work @haughty quiver -- Do you recall who made the tablet mount?

[willow pollen]

have you turned it off and on again?

it support deks here

*desk

[devout talon]

@haughty quiver thanks!

[eager sapphire]

IT Crowd reference, nice

[lethal lagoon]

@willow pollen that is prolly it puahaha

[rapid hornet]

@lethal lagoon one way to test is to be muted in hangouts and make a bunch of noise. it'll ask you if you meant to be unmuted then

[lethal lagoon]

@rapid hornet yeah - i am so careful not to accidentally unmute, i must have super duper muted it

[frail flame]

Perma mute

[devout talon]

thanks for the reactions folks. tindie store here: https://www.tindie.com/products/jgilbert/makernet-knob/

[waxen thistle]

"Percussive maintenance" might be in order.

[strange mantle]

@devout talon even your clear-cases-of-wire are neat!

[willow pollen]

or bribe the cat to fix it

[devout talon]

@strange mantle thanks. i really like making things where kids can look inside and see that the inside of technology isn't knowable

hence the clear plexi

[strange mantle]

@lethal lagoon don't worry, i think i'm batting about a 10% success rate these days using a web mic

[harsh bone]

TRON

[river peak]

@glossy glacier IS the electron microscope

[willow pollen]

i see a manufacturer brand on that snake scale

[lethal lagoon]

@strange mantle it's the hardest part of show & tell! 😃

[willow pollen]

adam needs his own show

fun with SEMs

[haughty quiver]

@waxen thistle it's a Makayama Movie Mount for iPad

[waxen thistle]

@haughty quiver Thanks! 😃

[river peak]

@willow pollen It wouldn't be a show. It'd be a SEM-inar

[clear matrix]

Semantics.

[willow pollen]

badda tish....

nice

[strange mantle]

@glossy glacier congrats on getting full screen working!

[lethal lagoon]

yay we got to the story! i was so curious...

[willow pollen]

that screen looked so clear (and two sided)

[muted mesa]

[frail flame]

I think the show coul be a little longer? Always seems so pressed for time. just sayin

[willow pollen]

always an astounding and inspiring show

yup, more time for sophie the wrangle her mic

[river peak]

People make the awesomest things

[lethal lagoon]

my next project will just be getting my mic to work 😉

[willow pollen]

there should be a show and tell charades sticker

@waxen thistle only for the curious, this is the Polaroid table tripod. I've had it since about 1983. Here's one on eBay https://www.ebay.com/itm/Polaroid-Small-Tripod-Stand-7-5-High-Preowned/152740112429?hash=item239005282d:g:dfAAAOSwnMRZ3s9C

a new character pin idea: Mike the Broken Mic

[solid wyvern]

adafruit is live at https://www.twitch.tv/adafruit

[rapid hornet]

you would think I would know what it is given I made it

[waxen thistle]

oh wow! thanks @haughty quiver --- I wasn't even going to ask about it since it was an older one. That's awesome.

[haughty quiver]

BTW, I will not be doing a livestream tomorrow, back to regular time next week.

[willow pollen]

nah.... sophie the broken mic.... fame at last 😃

[haughty quiver]

I'm guessing that one exists w other brand names on it @waxen thistle

it's go a nice wide stance, so stable enough for a lot of iPad angles

[lethal lagoon]

@willow pollen my cat, MIDI the Computer Muter!

[heavy siren]

That happened to me as well. No sound. Haven't been on since.. 😃

[willow pollen]

that works too

[gaunt plume]

ah its aiden!

[river peak]

I guess he's Aiden' the show today

[waxen thistle]

Bring him to the factory for cloning.

[harsh bone]

How many times on that card?... I'll so do it!

[severe inlet]

Aiden sent them a 3D model of himself for them to print.

i want a UPS truck

[clear matrix]

@haughty quiver Wide stance... lol.

[waxen thistle]

@haughty quiver My favorite brand of tabletop tripods are made by Oben (via B&H photo). I have a tall oben tripod that I use for the 7" display (https://www.adafruit.com/product/1667).

[devout knoll]

@open girder Are you guys adding more Countries ?

[river peak]

Hovercraft!? I want my Adafruit orders delivered by hovercraft

[devout knoll]

To Delivery Lists ?

[clear matrix]

My hovercraft is full of eels.

[willow pollen]

um

[brazen grove]

shame the other lines from that sketch are not family-friendly

[willow pollen]

you may need to get that looked at

[shell mason]

Hovercraft cool @clear matrix

[waxen thistle]

https://www.bhphotovideo.com/c/product/687342-REG/Oben_TT_200_TT_200_Table_Top_Tripod.html @haughty quiver is the one I use, along with the shorter TT-100 model.

[clear matrix]

@brazen grove Right? lol

[gaunt plume]

I can hear the machines

[brazen grove]

they are restless

[odd stream]

1st time on Show&Tell tonight ! Fun times.

[clear matrix]

@odd stream Yeah! Great to see you!

[brazen grove]

you look different than I imagined 😃

[willow pollen]

the second head was a surprise

[brazen grove]

the third hand helps with the ski boxing

[eager sapphire]

Ski boxing?

[open girder]

ok periscope says we need 186,000 more hearts, ya'll know what to do https://www.periscope.tv/adafruit/1vOGwNQZqaVKB

[eager sapphire]

Sounds like a sport

[brazen grove]

very popular sport aroudn Arcturus 5

[lethal lagoon]

consider it done!

[waxen thistle]

❤

[harsh bone]

Does anyone use Periscope any longer?

[river peak]

@open girder We're really putting our hearts into it

[willow pollen]

😦 i need to create a new periscope a/c... so not for a while

@haughty quiver This drink chiller was a really cool project.

[lethal lagoon]

@haughty quiver has the coolest vintage goodies! love fusing that with new tech

[haughty quiver]

you're the punniest, @river peak

[clear matrix]

@haughty quiver I love the eyebrow!

[river peak]

My second language is pun.

[haughty quiver]

thanks so much @lethal lagoon ! great eye ;)

grazie @clear matrix

[devout knoll]

Oh My bad habits of big screens is making my eye strain

[wintry plaza]

is this where I can ask a question?

[willow pollen]

you just did

[devout knoll]

@wintry plaza Yes

[wintry plaza]

i have a feather bluefruit board and GPS module running a stickfigure costume made of 5m of rgbW leds I wear while riding an electric unicycle, is it possible to change the colors/ program based off GPS speed? where would I find a guide for getting gps info into the feather or using it in my code?

[rapid hornet]

@wintry plaza the presenters won't respond until later in the show but we can help now

[wintry plaza]

ah great

[willow pollen]

"help"

[wintry plaza]

https://www.youtube.com/watch?v=wJKaC_mpNSE

[rapid hornet]

@wintry plaza seen this? https://learn.adafruit.com/adafruit-ultimate-gps/overview

[gaunt plume]

@wintry plaza what gps module are you using,?

[wintry plaza]

i have a feather gps module

itsnot wired yet

[rapid hornet]

then you want https://learn.adafruit.com/adafruit-ultimate-gps-featherwing/overview

[gaunt plume]

@wintry plaza If you're using arduino, try calling GPS.speed() from the gps featherwing lib and use the arduino map function to map the speed (in knots) to your the rgb vals of your lights https://www.arduino.cc/reference/en/language/functions/math/map/

that gripper is so awesome, especially b/c it's unibody

[brazen grove]

for a moment I thought the tendons are printed too

but it's very cool anyways

[wintry plaza]

thanks guys, just what I was looking for

[shell mason]

think gripper end of the telescope stick

[gaunt plume]

@wintry plaza no problem! if you need more help, head to #help-with-projects

[severe inlet]

My 3D prints never come off the bed that easily.

[gaunt plume]

@severe inlet have you used hairspray on your bed before?

[wintry plaza]

first time finding this discord, makes life much easier 😉

[lethal lagoon]

oh this is so cool, reminds me of doctor octopus tentacles

[eager sapphire]

Do 3D printers ever use teflon beds?

Or would that mess up the base?

[severe inlet]

No, I'll try it next time.

[gaunt plume]

@eager sapphire not sure, most are just boro. glass on a pcb @severe inlet check out aquanet, it's super useful if you have a glass bed

[eager sapphire]

Nichrome wire to heat the bed??

[frail flame]

Infill setting on the printer?

[devout knoll]

Thats 90°

[eager sapphire]

More than 90, looks like

[devout knoll]

Yeah !

[eager sapphire]

135

[pliant surge]

yup 135

[devout knoll]

I was about to type that

[pliant surge]

now in radians!
