[mystic ruin]

Nearly every kitchen would have what we call a grill (Americans call a broiler?) as part of the oven

so I've actually never seen anyone with one of these before!

Im going to try it out without messing with the electronics first, I just need to get some SMD boards to test it with

[obtuse walrus]

I feel like toaster ovens and related are more convenience items or for very small kitchens that don't have a built-in oven and cooktop

[mystic ruin]

ah ok,

[lusty siren]

Toaster ovens are very niche

[tidal citrus]

they are very good for fixing 3d prints

[lusty siren]

I feel like I hear more about people using toaster ovens for reflow/3D printing/etc than, well, actual toaster oven-ing

[tidal citrus]

well, you cant cook and make in the same oven, non toxic ≠ not actually
toxic

[leaden frost]

using frying pans for reflow is so passe

toaster oven pseudo-mechanical timer switches wear out fast enough to make it a disposable appliance so they are in abundance to convert or else in the recycling it goes.

[vocal horizon]

Toaster ovens are really good for melted cheese toast 😉

Word Clock using Feather M0 Express and CircuitPython https://www.youtube.com/watch?v=8hsHezrDnYw

[lapis jasper]

@covert field awesome! Do you have a write-up somewhere about how you did it?

[woven dagger]

I finished the video for my hydraulics safe! https://www.youtube.com/watch?v=57qfl9j-u0E

[covert field]

I created a shadow box for each letter with a diffuser sheet.

I used a 4-meter strip of RGB Neopixels and cut into 11 LEDs per row. Soldered rows together. Used Easel and X-Cave to create troves for the Neopixel strips.

I then wrote CircuitPython code for the Adafruit Feather M0 Express to drive it all.

supporting python code. converted to mpy to save memory

main driver function. due to limited memory, i was unable to get a UI for setting time. There are 10 rows of 11 lights. The codes map a 10 by 11 grid into one light in one of 2 light strips (top half of lights and bottom half of lights). The words are encoded as a start position and length (3-number tuple). I wanted to use all the lights, so I decide to fill all lights with a dim random color then place the time in words on top of that.

[lucid bloom]

I got PiGlass voice commands working I'll try and demo them on the next show and tell

[red cobalt]

I cut this one years ago, but the project inexplicably stalled. Maybe I'll pick it back up someday…
(I was pretty proud, being able to compactify into a 10 x 9 grid)

Have fun making!

@MakerSandbot#7501 by @Codingpro#9213

[uncut meadow]

Should I make a guide on how to make one?

[covert field]

@red cobalt I get stalled on projects as well. It looks great so far. What material did you decide to use as the faceplate? How did you decide on the LEDs spacing?

[red cobalt]

@covert field Black acrilic for the letters (still got the brown protective film) — which is going to be sandwiched with a thin sheet of transparent polycarbonate to secure the little floating pieces (from O, R, P, Q, A) in place. The spacing was only based on how large the overall frame should be.

[woven relic]

Does this count as show and tell??? video from my drone ive been slowly working on and trying to get flying as clean as possible.

https://www.youtube.com/watch?v=4mApdjrtqls&t=4s

[uncut meadow]

yep @woven relic

[tidal citrus]

I'm not sure if I my sunglasses were went for this

[strong phoenix]

neoPixels.setBrightness(25); is the first line i make sure is there in any neopixel code.

[tidal citrus]

it was at 50 for testing it's now at 15

[obtuse walrus]

Not exactly a maker project, but I spent a few hours on cleaning my PC, reseating every heatsink, and delidding my CPU today. https://i.imgur.com/71m7ehQ.png

I bent a couple pins in the socket and had to do repairs with a jeweler's loupe and a needle.

But in the end, it all works.

That is a 3D printed delid tool, by the way

The processor fits in only one way, and you clamp it in a vise to add pressure until the adhesive holding the aluminum heatspreader on breaks.

Very reliable way to do it, no chance of cutting traces or anything

If you're gonna do more than one or two chips, though, you can get steel/aluminum tools with built-in tensioner screws. At $30 you might just want to do that anyway if you don't have a vice, vs. $12 shipped for the 3D printed tool.

@solar yew I now have 5 voice commands 😁

[solar yew]

sweet!

Got outbid on ebay with mine went for like 154 + outraeous shippping I think they are 170 with coupon new so that stunk.

I have two adafruit video glasses I got for that purpose when they used to sell them, I might have to hack one up and do Noe and Pedro's version of google glass.

[mystic ruin]

Hey all, I made a video on using both fast cores of the esp32

https://youtu.be/KBxJ6xfT8Dk

It's actually really easy to do!

[lucid bloom]

@solar yew I did that they are hard to read because RCA

[solar yew]

yea that is why I been sitting on them so long been looking for something that is hdmi and vudine looks like the only option without ripping apart some ftv goggles or an old sony hmz and that has a huge box to plug into.

[lucid bloom]

Vufine is 720p and it's impossible to read the terminal without making text bigger

[solar yew]

yea most of my stuff is going to be tts anyway, I want to rely on the screen as little as possible, tts though bone condution should be much more multitask friendly.

[lucid bloom]

All I did with mine was shrink wrap it to the glasses frame right above my ear and it works great

[solar yew]

awesome yea that is why I want to be doing. ideally I want 90% of my info to be audio.

[solar yew]

looks nice and clean too

[woven relic]

@vernal ferry lol thanks!!!

[indigo charm]

@lapis jasper any room on show and tell this week?

[lapis jasper]

@indigo charm probably!

[indigo charm]

how does one get on the list? 😃

[bright hull]

@woven dagger cool. nice project. (and nice sticker 😃 )

[indigo charm]

After years of off and on fiddling trying to figure out how to put blinking lights on a beanie cap, I finally settled on a trinket with the neopixel strands. So much easier to figure out and power than my initial ATTiny13 attempts.

[stable kayak]

Awesome!

[indigo charm]

Now I just have to sew the lights into the cap. Part 2 of the project!

Electrical Design of my plane is working! (Sans Wings)

[hidden saffron]

Successfully lifted 18lbs of payload and 36 "passengers" AKA tennis balls. Using a turnigy 420kv, with a 1000W hard power limiter. Added in a prelimiter, which uses soft regulation to limit it to 980W. Now to add wheels and to take it down to florida to compete!

10ft wing span, 72" fuselage, 6 control channels

[indigo charm]

finished my blinking LED cap 😃

[leaden frost]

@indigo charm Yay, that turned out great. Could you make a light up propeller beanie? Asking for a friend...

[stable kayak]

Love it

[warped cobalt]

After seeing American Flag beanie, this might get added

[bright hull]

@hidden saffron nice. what airfoil section is that on the main wing?

[hidden saffron]

S1223 I think? I just design the Electrical system:P

[indigo charm]

@leaden frost hehe that'd be neat. Need to find a flat-ish motor though...

[bright hull]

@hidden saffron cool. no worries. it had an intersting profile so was just curious. good luck with the comp.

[hidden saffron]

Thanks! I just checked our report, S1223 RTL

[cedar dew]

Hey peeps. Just showing off my latest build inspired by Assassins Creed. The main piece of my build is the tomahawk head that I modelled in fusion 360, printed and finished then had it cast in aluminium. I used wood filler to give it more of an organic look where 3D printed gave me the symmetry and geometric shapes to work from.

[shut mesa]

Very nice

[red cobalt]

Holy cow! I gotta say, though… Assassin's Creed III isn't everyone's favorite game out of the series 😉
By wood filler, do you mean that putty you can find at the hardware store?

I have a friend who would sell their soul for one of those 😂

[solar yew]

.oO(that's probably what it costs..)

[warped cobalt]

That is awesome to see someone do prop and not have it just being plastic

[hidden saffron]

I might just have to attempt at a copy cat... put the aluminum melter to good use

[cedar dew]

@red cobalt . Whose not into buying a soul or two ;). That's right on the wood filler. It dries quickly and adheres to PLA really well. I cast some of my 3D prints in resin (cold cast) and for others like these, I know a dude that casts softer metals like bronze and brass.

All in all. The total material costs is around $100 with the biggest cost going into the custom aluminium cast. Resin is cheaper. Home 3D printing is not really good for production.

[cedar dew]

For some of the bigger prints, I use big 3D prints for structural shape then cover it with metal like this one https://www.facebook.com/makeitrealaustralia/videos/2024980614424689/

[long vine]

Probably not the most advanced thing in the world, but I rigged up my neopixels to my monitor and had them display my HP and power in WoW https://www.youtube.com/watch?v=VQgTnPSvGDM

[cedar dew]

@long vine that’s awesome. I think that just knowing how to take something so specific to a custom out is wonderful. If you could, what would you model around the lights? Like a long blade that gets lights up more or a row of dragon eyes

[long vine]

I was considering for my paladin putting a powerful LED plate with a cardboard cutout and a yellow filter to project wings onto the wall behind my monitor while using avenging wrath

only problem is I've not been able to find where to buy filters

[cedar dew]

@long vine I'd laser cut or 3D print the cutout with a lense behind it maybe or more powerful LEDs. If you're using it in lowlight, I think standard neopixels will work just fine. So just a static light or something that reacts to the game? Do you have an image of the wings you had in mind?

[long vine]

haven't started yet, I don't exactly have amazing tools for things, most my stuff is hand cut/sawed wood or cardboard

[cedar dew]

If you'll teach me how you pulled info out of a game to push to LEDs, I'm happy to share my skills with 3D modelling/printing

[long vine]

ah sure, getting the data from WoW was easy since they allow UI modifications

I installed an add-on called weak-auras and used it to colorize a pixel on the screen based on your character status in the game (had to write some custom LUA that WoW uses). Then with python I simply read the color of said pixel

that gives me 24 bytes to play with

bits even

[cedar dew]

Sounds simple to you but I'm a beginner to mocrocontrollers

[long vine]

which is more than enough since I have 8 bits for HP, 8 bits for power, and 8 bits for bitwise on/off flags for the panic button and if I'm mounted or not

[cedar dew]

I got as far as to copying and modifying sketches

and tryingt o learn python

[long vine]

the screen reader runs on windows

also during christmas I had a broken ornament which I replaced the LED in with one of my panels, and made a polar bear transcend. This is the difference in brightness: https://twitter.com/jasdoge/status/939607164670369793

Jasdoge (@jasdoge)

I bought this polar bear decoration with a color-changing LED. The LED glitches a lot, so I replaced it. Tho I think a 12V LED was a bit overkill.

Twitter

[cedar dew]

That is bright 😉 but good to know it would work 😉

[long vine]

yeah, you'll have to use a transistor or similar though if you want to use it with a pi

[cedar dew]

Makes sense. On projecting light, usually they use lasers to get specific images instead of cutouts

Unless you have a image in the middle with light around it

[long vine]

as far as reading the color of a pixel in python under windows goes, it's pretty simple
from ctypes import windll, Structure, c_long, byref def getPixelColor(x, y): parse = windll.gdi32.GetPixel(dc,x,y) return [parse & 255,(parse >> 8) & 255,(parse >> 16) & 255]

[cedar dew]

like the batman signal

[long vine]

yeah exactly! that's what I was thinking. Just gotta find some filters

[cedar dew]

I'm definately saving that

[long vine]

I only started with python for this project a few days ago. Most of this info can be found on stackoverflow by googling

[cedar dew]

ok cool. I'm saving your code so long 😉

[long vine]

I found python very easy to get into and learn

[cedar dew]

So in your case, you want something similar to a batman signal with paladin wings in the middle blocking the light?

[long vine]

the opposite basically

a cutout of wings in the middle

[cedar dew]

That's why I'm trying to move over.

I see

[long vine]

nearly all the code on my pi runs on node.js though

[cedar dew]

The challenge with that is that light beds around teh cutout and the detail would likely blend

[long vine]

I'd probably build a little box

[cedar dew]

I think if you make small cutouts, and space them properly, by the time it hits your wall, it might give you the effect youre looking for

[long vine]

anyways, it's really late here so I'm gonna catch some Zs. Was nice talking to you. Feel free to shoot me an IM if you get stuck, though I'm also a beginner as far as python goes

[cedar dew]

How far between your "projector" and teh wall?

ty and will do. Maybe send a image of the wings you have in mind when you have a moment and distance. sounds like an interesting idea to work on

@warped cobalt

[warped cobalt]

Turned out pretty well

[tidal citrus]

so I have to do a few end to end , then I will make it a tube

[warped cobalt]

Which reminds me, I do need black furry cloth to make a tail for one of cosplays

[tidal citrus]

depends on the animal

mostly yes

[warped cobalt]

This is an oddball one, I couldn’t find the correct tail after 2 years

[tidal citrus]

if you don't want to make it you could try to do a custom order from someone

[warped cobalt]

Yea, I don’t have that kind of money

I already paid good bit for main cosplay

[tidal citrus]

yeah, not cheep

[warped cobalt]

Especially for an obscured character

[tidal citrus]

you may have to find and trim some fur

[eternal maple]

CircuitPython-powered holiday window decoration NeoPixel strip controller is done! It's an upcycle of a near-antique 30W incandescent rope-lamp decoration. Here's the completed enclosure.

The guts.

In the workshop window for the nighttime test...

[eternal maple]

A couple of factoids: When powered-on, it begins a 6 hours on, 18 hours off cycle. Continuous mode is switch selectable. The 60 NeoPixels in the strip are running at less than 25% brightness, more than bright enough (!), drawing about 600mA total (3W). And yes, there's subtle random twinkling going on.

[strong phoenix]

looks fantastic, as always @eternal maple !!!

[eternal maple]

Thanks @strong phoenix

[bitter minnow]

@eternal maple love the design layout on the control box ....keep it classy

[eternal maple]

Thanks @bitter minnow . I recently started channeling old HP test equipment panel designs, for some reason. 😉

@solar yew

thats just one side there were a lot of people in the sab and I did not want to shoot them

[solar yew]

So where is this place? (function, not location)

[tidal citrus]

Albany Public Library

[solar yew]

Isn't the university near there? National Weather Service has some ties with them, I think.

[tidal citrus]

UAlbany is nearby

[solar yew]

We get our forecast from the Albany office, here in NW Connecticut.

Wasula is the forecaster to get to know, there. His forecasts are very good.

[tidal citrus]

ahh

It's right downtown

[solar yew]

I have a URL For the AFDALY:
http://kamala.cod.edu/ny/latest.fxus61.KALY.html

PFM: http://kamala.cod.edu/ct/latest.fous51.KALY.html

Where it says 'THOMPSON' it will sometimes say 'WASULA' who is still I think the lead forecaster for the Albany office.

[tidal citrus]

I did not know that, thats rather neet

[solar yew]

I probably have two hundred and twenty seven (heh) links for weather, but the FOUS51 report is my go-to to find out what the weather is going to be, and win all the bar bets about it in the process. ;)

[tidal citrus]

wow

[quasi vault]

Hoping to get on tonight 😃

[solar yew]

can i get a show and tell rank?

[humble dew]

Oh I was wondering how you get one. I'm Zack with the light suit.

Does anyone know who had the Deckard's Dream on show and tell a while back?

[hidden saffron]

https://www.youtube.com/watch?v=yJ_vitZswwo&feature=youtu.be?

@wise raft this one?

[leaden frost]

@wise raft If it is the analog synth you are referring to, I would only think this person would have been on show and tell with that kind of gear https://blog.adafruit.com/2015/04/03/crowminius-a-synthesizer-story-demo/

[wise raft]

@leaden frost That's not what I was thinking of but it's in the same vein and awesome!

This is the one I was thinking of. Deckard's Dream is a relatively new synth made in the spirit of the classic Yamaha CS 80, enabled by the re-release of the Curtis CEM 3340 VCO chips
https://youtu.be/9l_yCIJuF7g?t=29m31s

http://www.deckardsdream.com/

hmm.. CScott seems to be the owner's name

[strong phoenix]

aka: not-so-young-crow. 😄

[wise raft]

paging @sand quail

http://www.synthtopia.com/content/2017/09/18/deckards-dream-yamaha-cs-80-inspired-synth-audio-demos/

Mystery solved!

Little did I know I was in the (virtual) presence of a synth genius!

[sand quail]

Deckard's Dream is a prject by Roman Filippov, a friend of mine who despit being Russian makes his home in Tokyo. He uses my filters and oscillator waveshaping circuits.

He didn't have to use 3340s, it just made things a bit easier. 😉

[strong phoenix]

it needs an image of a unicorn on the front panel. 😄 🦄

unless the reference is to a different Deckard...

[warped cobalt]

This somehow has feelz of Deadpool involved

[sand quail]

https://soundcloud.com/paul-schilling/sets/vangelis-style-cs-80-soloing

[strong phoenix]

ok. right Deckard. Vangellis...could listen to that anytime.

[leaden frost]

@sand quail The first demo track threw me off, shouldn't that be reminiscent of Keith Emerson on a Yamaha GX-1 but probably still with CS-80 or electone DNA.

[wise raft]

@sand quail I could pick your brain for hours but other than perhaps your website can you recommend reading material for a relative electronics newb who is very very interested learning about the electronics involved in synths?

[leaden frost]

@wise raft look through this https://www.paia.com/ProdArticles/ They were like the Heathkit of synths back in the day.

[wise raft]

Hah, I actually built one of their kits quite some time ago with my dad

I think it was called the sub-rocktave divider

[leaden frost]

I could never afford a Moog, any model. and still can't.

[wise raft]

I have a friend with a Little Phatty Stage II. Quite nice

[sand quail]

@wise raft The ELP demo is the DD used to do GX1 voicing. The CS80 was made from integrated circuit versions of GX1 discrete circuits, so they sound very similar. Well, except for a GX1 being two CS80 voice systems plus a solo voice and a 2-osc pedal voice. 😉

[wise raft]

niiiice

[sand quail]

Paia is a good beginner's starting point. Some of my first kit builds in th 1970s were Paia. I knew John SImonton (the owner/founder) for 30 years until he lost him in 2007. He made engineers out of a lot of kids, myself included.

[wise raft]

Ok, thanks.

[sand quail]

In fact, http://www.paia.com/hallofam/oldcrow.htm

brb supper

[indigo charm]

Got my first 3D print back that I designed myself today 😃 Its unreasonably exciting to see a physical object you designed, even when its so simple and based off of other people's designs.

[leaden frost]

and impressed with the pro product photo shots you have of your build.

[indigo charm]

the secret is lots and lots of light

I need more lights, I still have too much shadow

[leaden frost]

I'm always fussing with a piece of scrap fabric as my backdrop which slides off of my chair that I prop things up on for pics.

[indigo charm]

yeah I've done that too. never enough space for a proper setup...

[scenic siren]

I built a tabletop lightbox photo studio with PVC, dotstars mounted on acrylic, and a stitched ripstop nylon diffuser. It's about 2 feet square not including the table it's built onto.

[indigo charm]

I'd love to see a pic of that sometime 😃

[scenic siren]

I wanted to try to write up a guide for it but I built it in a frenzy and didn't document it at all. I got another set of most of it to document wiring it up at least (and it's an excuse to add more lights to it 😄 )

Sewing riptop is a trick.

Used huge grommets through it to attach it to the PVC frame, so it's sort of suspended inside of it

[indigo charm]

neat

[scenic siren]

Everything's tied to the PVC using 550 cord.

The table's a bit reflective so I also have bars across the back of it that you can attach posterboard to which is dark and not so reflective.

Depends on what you're going for.

[leaden frost]

@scenic siren Have you ever thought about getting a serger? I run all kinds of stuff through it.

[scenic siren]

Every time I think about getting something like that, I try to think about how much I would actually use it, and then it never seems justifiable.

[leaden frost]

It's one of those things, expensive yeah but once you have one you wouldn't use anything else

[scenic siren]

Makes sense

This lamp was a bit large to photograph in it, so I had another piece of posterboard propped up really oddly or the diffuser was visible, but I took this recently using the lightbox.

https://cdn-learn.adafruit.com/assets/assets/000/051/093/original/express_SjopennaImage.jpg?1518831930

[leaden frost]

I've used a big piece of black microfleece for my dark background. The fuzzy surface texture seems to cut out all the glare and reflections which works well. But I take my photos with an iphone and it's hard to crop out the rest of the house mess it captures on the sides.

[indigo charm]

hehe yeah. clearning out enough junk/space around my project is always the hard part

[scenic siren]

Yeah I have a decent DSLR I use. The lightbox helps with the mess because it's somewhat enclosed, so simply don't put stuff in it and there's no mess to photograph. Trying to document stuff in the project room while soldering and so on? Nightmare. So much to clean up 😄

[indigo charm]

I need a new house first. This one is full 😃

[indigo charm]

Finished my status screen write up 😃

http://www.fischco.org/technica/2018/status-screen/

[vocal horizon]

It would be nice to have a permanent space for project/product photos - I have a portable booth,but usually put it away to have space for nolling, boxes, etc. Also all the lights are free-standing, and it would be better to have them all on some sort of clamped/connected arms.

[cunning quest]

Prototype T shirt cannon. Uses lack of air pressure to fire. Going to a local science fest to show it off.

Hopefully doesn’t explode

[tidal citrus]

is it schedule 40?

[cunning quest]

Yes

Everything is pressure rate

D

My only worry is that the plug inside will explode

[tidal citrus]

oh, what did you use?

[cunning quest]

It is a all purpose caulk formed to the inside

The pressure difference fires the cannons

[leaden frost]

@cunning quest How does it work? I don't get "the lack of air pressure" thing.

[tidal citrus]

I got the fabric

[leaden frost]

that's cool! is that hand sewn individual neopixels or leds?

[tidal citrus]

That's the matrix

Im still at the store

[leaden frost]

ah, under the fabric?

[tidal citrus]

Yep

[leaden frost]

It's tough to find the right fabric with blackout properties when unlit so it will look like magic when the words appear.

[tidal citrus]

Yeah

[cunning quest]

@leaden frost it’s a little complicated. Inside the barrel is a smaller pipe. The inner pipe is what holds the shirt and the space between the inner and outer pipe holds the air used to fire it. The inner pipe is cut 2 inches shorter than the outer pipe. The space between has a 1 inch caulk plug. The plug moves forward when you bring the cannon up to pressure. Now the air in the barrel and the air in the control valve are at the same pressure.

Once you open the valve, there is less pressure behind the plug, so it moves back. The air than moves into the inner barrel and fires the cannon

It is just a way to make a more compact cannon without the need for a compressor or a air tank underneath

[leaden frost]

interesting, it would be nice to see a video of it in action.

[cunning quest]

Sure

Once I am done with the build

[humble dew]

@cunning quest Hmm if there's a failure in a vacuum based system, wouldn't that be more of an implosion?

[cunning quest]

Not a full vacuum

It is just using the lack of pressure

Still air there

But

The full system looses a lot of air quickly, and that can be considered a vacuum for a second

[tidal citrus]

@leaden frost it's going to be painfull waiting till tuesday

[summer shoal]

these are few of my shenanigans I did some time ago

and this is a rose i made

basically it has a temp sensor in stem

so as you touch it

temp was mapped with intensity

it goes brighter on touch

Thanks for sharing <3

[lusty siren]

De-panelized a bunch of DigiBadges. Need to remove the battery packs, then use the hot-air rework to remove the ATMega328

To replace it with a 328P

Because typos are annoying, especially when you don't realize they happened until you get the stuff...

[strong phoenix]

hey, I watched Murder On The Orient Express last night...

and yes, tyops are annoying.

[summer shoal]

@strong phoenix and how was it ?

[strong phoenix]

it was good. been a minute since i watched the original, and even longer since i read the book, so i will refrain from those comparisons. i didn't realize Daisy Ridley was in it until we started watching it; didn't even recognize her in the trailers.

7 Successful Flights, with 12 lbs payload and 24 tennis balls

So satisfying to see a design you've been apart of, work so well

[leaden frost]

@hidden saffron Cool! What is the purpose of using tennis balls - simulate volume it can carry or live load?

[hidden saffron]

The competition is to simulate a passenger aircraft, so each tennis ball aka "passenger" has a carry on of 0.5 lbs

Makes it difficult to stream line the bulk

[leaden frost]

ah, thanks. I guess it has military applications also.

I mean, Lockheed martin and DARPA are our biggest sponsors...

Daily Air Cannon Update

Blew itself apart

[proper kindle]

Found an interesting teddy bear and gave it some brain surgery
https://drive.google.com/open?id=1pH2u13vjGSAEHS8wyleZnzZTetu0fxqd

Now it just needs a more diverse sound library, and the ability to connect bluetooth audio to raspberry pis. Apparently that's impossible right now 😕

that is scarier than Freddy Fazbear

[summer shoal]

[solar yew]

The idea is encapsulated (use your imagination here) in the image of being able to take your granddaughter here. Implication is that the little one is about 6-8 years old and that you are a concerned grandparent, and do not wish to be embarassed or to expose the child to undue nonsense that isn't about electronics 'and stuff'.

So, stand back and let the child curse the robot!

[eternal maple]

There are some very creative children on this server (like my granddaughter) with some wildly imaginative ideas. I would be disappointed if their parents took away their Adafruit Discord privilege because it was too much like other interweb technical forums.

[solar yew]

We do not know who may show up here tomorrow, for their very first visit here.

[summer shoal]

well when you put it like that

[solar yew]

Could be the person who figures out how to move that asteroid that was going to smack directly into the Earth, many years from now. ;)

I'm the only person in my town who knows what a string car and python is (they have to know what both are to knock me out of the only-position).
I could say I invented string cars and I'd be believed. after explaing what one is.

I wouldn't do that -- I did not invent them.

[eternal maple]

Nor did I. My mechanical engineer turned comp sci younger brother came up with the idea we use. However "clothesline racers" were around before we started playing with string cars in 1976.

[solar yew]

I finally watched one of the videos you posted. It's a great idea.

I especially like the 'how do we stop it' part.

[eternal maple]

It's a good excuse to geek out about some extreme propulsion ideas and off-the-wall (no pun) sensors. Now that we're adults, we create more eye-rolls when we talk about it than when we were kids.

Was that from the Learning Guide?

Corners and circles are our next challenge. We have at least a dozen ideas that will likely work. A couple of them involve 3-D printing, so there's that...

[solar yew]

Haha corners!
I don't remember at all where I saw the vid but it was in last 3 weeks or so. If you wrote a guide maybe I followed a link or an embedded vid.

I don't remember breakfast. ;)

[eternal maple]

Yes, there was a linked video to a race after a class I taught at the local makerspace. It was great to see the adults in the class become kids again -- and competitive when the end-of-class race began.

[solar yew]

In 70 years they'll have them that can operate a rope swing across a river and land on dry shoreline. ;)

[eternal maple]

Another fun project to consider!

[solar yew]

'by letting go off the end of the rope at just the right moment

[eternal maple]

See what you can invent, @solar yew

[solar yew]

Better than Dads competing with other dads pretending to 'help' with Pinewood Derby.

I haven't really seen that but have heard stories.

[eternal maple]

Yeah, same here. Grade school science fair was another of those pseudo-contests where it was easy to spot extreme parental contributions.

[solar yew]

Right. I like stuff where the young person was inventive on their own.

[eternal maple]

Indeed. The good news is that, at least in my experience, there were only a few where the parent may have done almost all the work. There were some exceptionally brilliant students who did some surprising things. I still recall the miniature MRI that one junior high student made. Wow.

[solar yew]

first time playing with an LCD screen and displaying info from a input device. I cut and pasted code from 2 different tutorials to get it to work but im happy with this simple sensor/display I rigged up. 😁

[summer shoal]

Aye you almost broke your charger cable @swift hemlock

Get some heat shrink tubes and fix that before it goes ded

Also 2 things
What's the name of sensor you are using
2nd try to work eith new oled i2c display they look absolutely stunning

[swift hemlock]

haha yeah thanks it seems ever since I got this laptop that the plug construction has been pretty shoddy

[summer shoal]

paper tape it and heat shrink tubes should hold it

[swift hemlock]

im using a DHT11 temp/humidity module with a arduino uno clone

ill look into that, ii think i got some shrink tubing around here somewhere....

[tidal citrus]

almost ready to fully solder ... then I can have the flora under it all

[swift hemlock]

wow

[tidal citrus]

it's going to take a waile to 3d print tho backing

and you know how impatientint makers are

@tidal citrus that's where a laser cutter is handy....

I am working on documenting it and trying to write a learn , I will likely need a bit of help on that

[spring elm]

i've really enjoyed working with neopixels

i made an illuminated running vest that blinks in morse code and then created some bike lights that also incorporate a charlieplexed matrix

[tawdry echo]

First I thought I would share this little project I did on the Adafruit forums but there didn't seem to be a good fit there. I'm assuming this is a good place to share projects? Hey, if you know some answers here's another question - How do projects get listed on the Adafruit blog?

Not sure if this is the place to share projects with the Adafruit community but I'll give it a shot. A simple soldering project. I think of it as a miniature copperhead snake. However, I must say I was inspired by that python snake Adafruit uses . I was salvaging some copper from an old cable and noticed that the braided copper shielding looks a bit like a snake. Here's two pictures of my copperhead creation:

copperhead snake project

[lapis jasper]

@tawdry echo I can post to the blog. Do you have it posted somewhere online publicly already?

[indigo charm]

@lapis jasper how does one submit something for the learning system? I've got a writeup on my blog for my little status screen project that might make a good learning guide: http://www.fischco.org/technica/2018/status-screen/

[tawdry echo]

@lapis jasper I posted two picture here. I didn't write up anything about it. Very simple circuit with a battery two LEDS and an resistor. The interesting part IMHO was that the braided copper shielding from an old cable I was tossing out can look like a snake when you curl it. Feel free to post the pictures if you like. Also, this snake idea could be used to make the Blinka mascot for Adafruit. thanks

@summer raven Awesome! Hard to tell from the video, but what are you using to control the ears? Continuous Rotation servos, stepper motors, standard DC motors?

[summer raven]

@lusty siren they are standard DC motors with some gears and a rotary encoder

It looks fantastic!
I don't like people saying their projects are ugly! I won't allow it! Not on my watch!

[drowsy zinc]

Haaa! I see what you did there 😄

[hidden saffron]

BPM is that a heart rate?

[eternal maple]

@drowsy zinc Nice retro look/feel.

[drowsy zinc]

It's supposed to be 😄

But in the demo I didn't apply any kind of calculation or anything to estimate BPM

I figured for proof of UI I'd just put an incrementing digit in its place temporarily

The graph works though! But there's quite a bit of noise with the sensor

in that video it wasn't attached to me though

[hidden saffron]

Also from experience, uni provided components are not nice. Especially in a lab exam when you get faulty multiplexers

It looks pretty slick so far though!

[drowsy zinc]

Thanks!

I just wish they would give me a budget or something!

They sent the journalism students to new york for free

[junior agate]

capstone project for senior design is at a good point so might as well post it here. it's a lab mouse positioner apparatus for safely administering eyedrops to lab mice. the current process of a human holding the mouse is incredibly imprecise (and frankly not the best idea - my hands used to shake when soldering). no needles are involved, its an eye-dropper.

it moves using steppers and a bunch of high precision linear slides. the control electronics are based off of the reprap project - ramps 1.4 board and pololu stepper motor drivers. it's fully controlled using a QT application I'm working on which sends gcode (if it's precise enough for machining tiny parts...) and monitors the two cameras.

and...this did not go without a little #sparky

[dense lance]

Converted an old wired GPS module into a wired + wireless combo with a Teensy 2 as serial pass through/power and an HC-05 module for Bluetooth rfcomm connectivity.

[vernal ferry]

@drowsy zinc cool! what MCU/Display did you use?

[drowsy zinc]

@vernal ferry I started with a Lilypad of all things, then moved onto a Teensy ++ 2.0 that I salvaged from another one of my projects, and finally settled on a Teensy LC, it's all Teensyduino because I needed the 48MHz for quicker redraws on the screen. The screen has remained the same throughout, a cheap and nasty 1.8" ST7735 LCD 😃

[lusty siren]

Mostly working. No controls yet, but almost all of the individual components are together.

[tidal citrus]

cool

[fervent beacon]

What is it

Andon

[tidal citrus]

@fervent beacon use the @ to mention people

[solar yew]

"I saw @AT-AT at an attic sale at Attica," he said at length.

[tidal citrus]

that was amazing and horrid all in one

[lusty siren]

Oh, sorry, @fervent beacon I didn't see your message.

It's a "Digital Color Communication Badge"

Backside has an ATMega328P (Same as an Uno), a 4M Flash chip, a trio of buttons, and an SD card slot. Front has one of the small 1.77" displays.

Basically designed to be a digital version of this, but with added things: https://autisticadvocacy.org/wp-content/uploads/2014/02/ColorCommunicationBadges.pdf

It can load 24-bit BMPs from an SD card, and either display as a static image, or cycle through as a slideshow.

And I've also programmed in the various Pride flags - LGBT (Shown above), Bi, Trans, Pan, and Ace.

Most of the pins are broken out, and it runs natively on two AAA batteries - Although it's currently running from USB since I'm still programming it.

[tidal citrus]

did you create the board yourself @lusty siren ?

[lusty siren]

Yep!

[tidal citrus]

i tried to guess at what sscreen it was

[lusty siren]

It's the same ST7735R screen that Adafruit carries

[tidal citrus]

ahh

[lusty siren]

https://www.adafruit.com/product/618

[tidal citrus]

I was close

I love the idea

can you set it up to pass through a few flags?

[lusty siren]

Oh, it's entirely switchable.

The three buttons let you switch which image/badge/flag you're displaying.

(That's actually the code I'm writing right now)

[tidal citrus]

like pan, rebel alliance , Independent Planets...

[lusty siren]

Well, "Graphic" flags would have to be loaded onto an SD card

[tidal citrus]

thats not to hard providing the art could be found

or mathed

[solar yew]

How about a non-proud pride flag

[lusty siren]

And it can't cycle between "Graphic" and non-graphic flags. But you can put in graphics of the programmed stuff and it'll cycle through them as well

@solar yew What do you mean?

[solar yew]

"I'm not proud of anything: and I'm proud of it." << like that

[lusty siren]

I'm not sure that has a flag.

[solar yew]

I think as soon as it comes into existence it goes out of existence so we can't see it, but it's always (and never) there.

[tidal citrus]

i think someone put an apathy pride flag on reddit

[lusty siren]

Was it just a white rectangle?

[solar yew]

A transparent gif. But -- giving it a shape exhibits a form of pride, so it has to be a shapeless, borderless transparent gif.

[tidal citrus]

idk

[lusty siren]

A guy I knew in high school was supposed to do an "Emotion cube" with sides decorated appropriately. I recommended apathy... so he just whimsically drew a few lines with a pencil and called it good.

[solar yew]

How many people must exhibit apathy before the term loses any meaning?

[rain escarp]

I don't know, @solar yew .... I just didn't feel like looking it up.

Hahaha.

[indigo charm]

wow, that's an impressive board design! did you have those manufactured or did you solder that all by hand?

[rotund stag]

I hand-soldered them.

[tidal citrus]

I have not seen one of bunnies in years

@summer raven what else are you planning on doing mwith it

[rotund stag]

If you enjoy hand-soldering... Hahah.

[tidal citrus]

something tells me that those are tiny

[rotund stag]

Those are 0402 caps. They're really easy to break when you put stress on them.

[tidal citrus]

wow

Good idea: "cover it in kapton tape until it can't move" to help you solder.

Bad idea: "cover it in kapton tape until it can't move" to help settle down rambunctious children.

The End.

[lusty siren]

But @rain escarp - Settling down rambunctious children can help you solder!

[obtuse walrus]

I bodged together a little Conway's Game of Life widget this morning https://youtu.be/-G3ekcUMJYM

[obtuse walrus]

Right now it just resets to a random initial field (50-50 chance per LED of on or off) every 30 seconds or when the field dies out, but I plan to add some more features in the future like some interesting preset patterns, static field and period-2 oscillator detection and timeout, and variations on the rule set. Also, it currently wraps the edges, but for some patterns I will implement the option for one or more edges to go out past the display and end

Unfortunately a lot of the really cool patterns would require a bigger area, but this is still pretty neat

and since I'm using a Feather M0, there's huge room to grow

[humble dew]

Few more pictures from yesterday's testing.

[spring elm]

@obtuse walrus do you have a github for that game of life code on a feather? I use a charlieplexed for my bike's rear light and that would be a cool effect

[obtuse walrus]

Not yet. Right now it's pretty built-to-spec code. I can give you the .ino if you're impatient

[spring elm]

I can wait ; )

[obtuse walrus]

Righty-o!

[spring elm]

but when ever it's ready I'd be interested in seeing it

[obtuse walrus]

FWIW it's not too hard to bodge together a Game of Life. That one took me about 75 minutes from start to finishing debug, not including 20 minutes of reading Wikipedia to get a few ideas for implementation

It's basically double-buffered - two arrays, one displayed, and one to hold the next generation, then the toggle switches which is displayed and which is the target for calculations

[spring elm]

Ah ok. Sounds like a good next mini project. Thanks for the reference

@rain escarp It's just another computer heh. Using it as IO since I dont have an OTG hub at the moment

GPD Pocket

[rain escarp]

@dense lance That's a cute little thing!

[drowsy zinc]

Always wanted a GPD Pocket but I'm too frugal, couldn't rationalise the purchase with one laptop already running fine haha

[rain escarp]

@dense lance What do you think about the GPD? I've looked it up....and it seems, interesting.

I have mixed feelings about it from the reviews I read, but I always value the thoughts of someone who actually owns and uses a device over a paid reviewer 😃

[dense lance]

@rain escarp It fills a very specific niche. I wanted something a little more than a tablet/netbook that could replace my bigger laptop for portable tasks but not be too gimped. Actual quad core (no HT) and 8GB RAM were a couple of the bigger reasons for getting it. Having used so many craptastic portables with 2GB RAM, it was refreshing to see it at 8. Screen is amazing (7" 1920x1200) which is honestly a bit dense for my eyes but with a little scaling, works great (Plus it's nice having the slightly extra vertical screen space of 16:10). Touchscreen works well when I don't fat finger stuff. Keyboard is probably the biggest letdown. Its ok for light typing but some are just in akward locations (I'm looking at you tab...) and others take a bit of force to even register (also the aforementioned big hands doesn't help one bit). Performamce is great for what it is and has been doing everything I was on the larger machine (web browsing, RTLSDR, compiling, etc). Battery life is spot on too. Idle I can hit about 1W usage with the 25Wh battery (so lighter usage I can hit about 7-8 hours). Plus just being x86_64 has been great for running Linux, Android, and Windows (I have all three booting at the moment). Storage is a little eh due to being eMMC but the 128GB capacity makes up for that a bit.

Oh and all hail our USB-C overlords.

Love having it on it.

And trackpoint is pretty sweet too. Looked at a teardown and it's the same one some of the HPs use (Elitebooks I think)

[rain escarp]

That honestly mirrors a lot of what I read -- biggest critical component is the tiny keyboard.

It's like the concept of a netbook refined to a beautiful finish.

[dense lance]

@rain escarp aye the case is nice. Everything's aluminum except for the hinge cover (they had to put the WiFi antenna somewhere, heh)

Or just fact the case is done?

[lucid bloom]

It's done I didn't screw up the dimensions this time

[warped cobalt]

Ah

[lucid bloom]

I will eventually upgrade to a pi 3

The zero is quite taxed

[warped cobalt]

Ah

Maybe they’ll make a Zero+

Or some new version that can handle more

[lucid bloom]

The case reduced assembly time to 30min

No cutting or drilling

[warped cobalt]

Noice

Thus why 3D printing is liked

[lucid bloom]

@warped cobalt in about a month I am going to go to a field where they said I could use it

[warped cobalt]

Of course ya gotta field test it

[lucid bloom]

Yea it records video the whole time too

[warped cobalt]

Well, that explains the taxing

[lucid bloom]

That and I'm displaying a video feed with overlays

[warped cobalt]

Well, I figured the video feed was pushing it’s limits, of course overlays helps

[lucid bloom]

That's what you see on screen minus the black edges

[warped cobalt]

Well, next week, I’m sure ya’ll have all kinds of way to show this toy off

Probably post some vids of ya out using it on fields

[lucid bloom]

As soon as I make them 😉

I have only done target practice with it so far

The field closest to me won't let me use it because it is an "unfair advantage"which is what I was aiming for

[warped cobalt]

Hahahahahahaha!

Well, to be honest, as least I now know what to use for FPV set up in RC plane if I ever get around to trying it

[maiden sluice]

I just finished all of the wiring on my 8-step synth sequencer today. The enclosure is all 3d printed. I love it, and wanted to share.

[strong phoenix]

@maiden sluice nice work!! got a project page anywhere? would love to look under the hood. also that synth will be more than welcome on show & tell next Wednesday if you have some webcam-ability.

[maiden sluice]

@strong phoenix I documented some parts of it as I went on instagram, but honestly I was mostly mindlessly soldering while on work calls.

here's the guts... top was the breadboarded version where I figured everything out, bottom was the cleaned up soldered version.

it's just a 4017 into an APC. Nothing that hasn't been done a billion times, but this one is mine 😄

@solar yew have patience. it’s cool!

[keen temple]

I am designing an elecro-mechanical clock. Instead of winding the clock every 2 hours, a servo will slowly wind the clock; in theory. What does everyone think of the design/colors? This is remixed from TheGoofy's clock: https://www.thingiverse.com/thing:328569

[warped cobalt]

TheGoofy?

[lapis jasper]

@keen temple I like the colors!

[strong phoenix]

@keen temple dig the colors as well. reminds me of a lot of the Ferrari watches (non-yellow ones).

[solar yew]

Haven't really made any like "real" stuff but my github has a fletching bot for osrs and right now im working on an app that scrapes this 1 car website for good deals https://github.com/Fuchsiaff

[lusty siren]

Scraping a car website? You must really be driven

[eternal maple]

Glad I left that blob of blu-tack on the soldering bench. Was in production mode today with about 25 wires to tin. Could easily work on 5 wires (10 ends) at a time.

[tidal citrus]

handy

[thorny bluff]

Needed a way to have light in all directions... insert one used thread spool and double-sided fender tape... 😉

[eternal maple]

@thorny bluff clever!

[eternal maple]

Okay, I'm kind of liking my new blu-tack-blob "helping hands." As I get older, my hands quiver a little more each year. Getting the connection closer to the soldering benchtop makes it really easy to steady the tools by resting the heels of the hands on the same level as the action. Made fast work of some repetitive soldering for the current project. I'll set aside the PanaVise unit for bigger projects.

[rain escarp]

@eternal maple I remember a photography book I read called "Irreverent Photo Tools for Digital Photographers". It was full of little DIY tricks like this. It discarded the notion one had to drop a lot of money on overly expensive photo "pro tools" when duct tape, clothes pins, cardboard, and twine would do just as good of a job -- if not better.

Your blue-tack reminds me so much of that mindset. 😃

[eternal maple]

The "folksy" approach? I use a lot of blue painter's tape, too.

[fervent beacon]

DIY or buy is the question

[hidden saffron]

I might switch to that from scotch tape

[burnt wyvern]

I can’t solder to this because it’s magnetic and it tries to swallow my soldering iron lol

[eternal maple]

You need a couple of these (and a crimping tool):

[burnt wyvern]

I know I solved the problem

[vernal ferry]

nice tip @eternal maple ! 😃

[solar yew]

been educating pc modders on the magic of rgb addressable led strips

now guys want to come visit and learn more

i think this is a good start at growing a comunity

[solar yew]

thanks again!

[tidal citrus]

someone asked me about the backing

I am still tweeking it

[cunning quest]

@lucid bloom do you have a write up or tutorial on the piglass

I want to make one for my air cannon

[clever pebble]

have you think getting fairbelt 3D printer? so brinting that could be easier?

[cedar dew]

I’m liking Kratos’s Axe and thought I’d make a smaller version as Viking styled bearded axe.

[vernal ferry]

@cedar dew ooh awesome! are you planning on adding LED's in?

[solar yew]

Hello everyone,

I have been wanting to do a project for some time now and it's taken me alot of time to gather all the piece's.

[cedar dew]

@vernal ferry I’m going to have this model cast in Aluminium and brass. I may do a light up version later

[lapis jasper]

@solar yew what are you doing with those parts?

[solar yew]

@lapis jasper https://cdn.discordapp.com/attachments/262729163423744000/431525795828072466/download.jpg

[solar yew]

basically to be a read out for my instruments, oscilloscope, multi meters, ect

never to have to turn my head when i am neck deep in a DB box or touching fine pads on a board

[lapis jasper]

@solar yew that sounds super helpful!

[neon island]

Created a library for props. Here's a video demo and the github link: https://www.youtube.com/watch?v=dvatEOpsaqw

[solar yew]

@lapis jasper

ok so i have made the plan to add additional functionality

i have in my picture at the top there i have the following parts,

2X rapberrypi's
one of the is the zero W the other is a 1.3 no W

1x micro usb hub 4 ports

1X 15A@5V power bank,

1x 10A@5Vpowerbank,

1x HD camera module,

1x micro hd 720p display "monocle"

a wireless keyboard with airmouse support "but will only be used for a back up interface for control"

the plan is to have 1 pi run open CV

and feedback to the main pi,

the main pi will draw the ui and all the sensor data, including the camera feed from pi the other pi

the servo's will be used to adjust the position of the device remotely,

the are now 3 in total

added to this i am adding a very tiny but powerful network router that can allow 4G, wifi and even AP, wisp support,

i am going to record the build soon

just waiting for my soldering iron to arrive,

So now the question,
i need to either build instruments into the device, "could be a good learning exp"

or do i add transmitters into my multi meters and tools ?

my last iron died from much work,

god rest it's soul

[lusty siren]

So, it looks absurd and a bit hideous

BUT

It's a procedurally-generated tectonic plate map.

[leaden frost]

@lusty siren You sure that isn't the new digital camouflage pattern for the military?

[lusty siren]

Hah! A little too bright.

[leaden frost]

Or is that an IQ test to name all the countries that fit the shapes?

[rain escarp]

Ooo, it's a Rosarche Test 2.0!

[leaden frost]

I definitely see squirrels.

[rain escarp]

Oh, that's nonsense. When I look at that, all I ....SQUIRREL!

[leaden frost]

wait...now I see two squirrels...and they are arguing over how to pronounce LaTeX.

[rain escarp]

There are more than two squirrels doing that, bub 😃

Seriously @lusty siren that's pretty nifty

How'd you go about doing that?

[lusty siren]

Python

It's pretty simple, actually

Just give me a minute, I'm looking for something at the moment

[rain escarp]

If you're looking for my marbles, trust me -- I've tried to find them. No luck whatsoever.

[lusty siren]

I can't remember what they're called, but the group of 8 mini switches in a single box

[rain escarp]

DIP switch?

[lusty siren]

YES

[rain escarp]

http://www.hobbytronics.co.uk/image/cache/data/sparkfun/dip8-switch-500x500.jpg

[lusty siren]

THat's the ticket!

So, how does the plate generator work? Fairly simply, currently.

It creates a grid of boxes.

And then

It picks a spot for the "Origin" of each plate.

Making sure they're not too close to the poles

Once it has that, it picks adjacent unclaimed boxes for each plate, and claims them for that plate.

Repeat until all are claimed.

[leaden frost]

@lusty siren You should look into all the "digital sand" programming by @hot ivy sounds a lot like the logic used - Conway's game of Life, etc to produce the adjoining cells (emergent behavior) There's a guide in the Learn for it.

[rain escarp]

very nifty

[lusty siren]

@leaden frost It only needs to do it once, not repeatedly.

[leaden frost]

if you want to conquer the universe, start small, make sure that works and expand.

[lusty siren]

What I want to do now is make a topography map. But boy, is that a lot harder to logic out.

[leaden frost]

I think the term is "terraforming", there are probably some programs out there already.

[lusty siren]

Well, yeah, but they're not mine.

And a significant number of world-map-makers just use fractals which... never look right

[leaden frost]

Find a minecraft expert.

[lusty siren]

I want to use the information I'm making with the tectonic plates to make a map based on said plates.

[leaden frost]

Something interesting to try is if you can get your "map" into a vector .svg file, import that into Tinkercad and it will extrude that into a 3D surface and then export it out to 3D print.

[lusty siren]

That'd be cool.

Man, it certainly takes a a while to chug along on these larger-sized maps.

[leaden frost]

pull your outline map or really any low res black/white graphic into inkscape, use the path conversion tools to get it out as an svg file and into Tinkercad. You'll get a pretty cool relief topo map.

[rain escarp]

If you can figure out how to do a topographical map, that'd be such a relief.

[lusty siren]

Added in weights for caring about plate direction.

And speed.

It looks far better.

I also added a method for random seed, so maps can be "saved"

A map, and

A gif!

[rain escarp]

A wild gif has appeared!

[lapis jasper]

@solar yew My guess is that its easiest to use a webcam to monitor a tool or more. @lucid bloom will have tips on using raspberry pi and a heads up display

[fiery plank]

i have several dip switches that has only 10 pins and it has two pins dedicated to vcc and gnd. so, you just have to have the power and ground and what you want to turn on and off

I cant find them anywhere

[cunning quest]

@leaden frost you asked for a minecraft expert?

[signal loom]

Who would be interested in a glowforge unboxing

[manic elk]

How does show and tell work?

[solar yew]

@manic elk From what I understand after you finish a project send a pic of it tell everyone what it is and how it works and whatever then everyone has a conversation about it then soon starts to get off topic until someone else shows another projects I actually like this page cause you get some ideas then they talk about stuff you might need to know in the future

[manic elk]

Doesn’t Adafruit stream something about show and tell?

[solar yew]

I have no clue

They might I haven’t checked into it

[manic elk]

It’s a Google Hangout thing every Wednesday, apparently.

[warped cobalt]

I went to Primitive Skills class

[leaden frost]

@warped cobalt Is that a recorder/flute mounting or cleaning hook? or something unrelated you made in blacksmithing?

[warped cobalt]

1st one is side blown flute

2nd is recorder/flute

The hook is unrelated I made learning blacksmithing

I made with intention to hang a lantern from tree branch, so I can have it in reach

[leaden frost]

Here we go with LED Firefly Jars, there is a Learn guide on neopixel Tiki torches.

[warped cobalt]

I haven’t had luck with LEDs being bright enough to light up campsite, but I would still have need for the hook if I did

[leaden frost]

We had a recorder music class in elementary school. It was amazing that the teacher could pick out who was not playing the right note or not even blowing.

[warped cobalt]

My elementary music teacher was fantastic also, she spent time to teach each kid, and tried to give us a chance on a different instrument if we couldn’t play, or didn’t like it

I failed at all of them

For some reason tho, I managed to play this one

One guy kind of looked at me and asked if I played before

The guy who taught how to make them explained how to do fingers

[leaden frost]

My daughter kids me that I can't even play the kazoo right. As long as you have fun with music.

[warped cobalt]

Oh, the instructor at this event gave 5 minute instruction on how to play it, then said “have fun with it”

All his instruction was to blow correctly to make noise, and order of finger lifts to hit the notes

After that, enjoy!

[leaden frost]

How do you get to Carnegie Hall. Practice, Practice, Practice.

[warped cobalt]

I’m still trying to get noise out of the side blown

That is how ya get anywhere

[leaden frost]

On the bucket list is to make a set of bagpipes.

[warped cobalt]

We knew when his first class finished, ya heard them all over the place

I don’t know if I’ll make one, but my bucket list is to learn to play one

[leaden frost]

Someone had jammed in a few recorders into a garbage bag and made a set of bagpipes.

[warped cobalt]

Heh

[leaden frost]

but true bagpipes are reeded instruments

[warped cobalt]

Yea

It’s certainly interesting to learn the steady breath for such

[leaden frost]

second on the bucketlist is accordion or concertina or maybe harmonica

btw if you need a lot of light for campsite, look up those COB(chip on board) flashlights. The new style LED element is super bright and relatively lower price than more powerful LEDs.

[warped cobalt]

I will check it out, also considering I may have to figure way to power it for like a week

The event I was at lasted 4 days

And I found they have some for longer

I have a 25w solar, but that doesn’t help the most in heavily wooded areas

I have been learning harmonica for bit, it’s actually entertaining to do in woods

[lapis jasper]

@indigo charm Awesome! I'd love to do the same thing running an old kindle display

[rain escarp]

@lapis jasper @indigo charm +1 here, I have a couple of old kindles w/ keyboard sitting around, which would be awesome for projects.

[lapis jasper]

@rain escarp Old ones are readily available and the screens are great. I think they are hard to control though

[rain escarp]

@lapis jasper Last time I looked into this (a few years ago), it was not an easy process. Involved some SMD soldering, high risk of bricking, breaking open the hard-to-open case, etc. I put any thoughts of using them on the backburner, though their screens are excellent quality for the price one can get them for.

It's one of those "it'd be nice someday" projects 😃

[lapis jasper]

yeah, for me too

[rain escarp]

And with the Red/Black combo eink being literally plug-and-play with RPI/arduino platforms....looking at the time invested vs cost, I keep leaning towards the easy road.

[lapis jasper]

yeah, but none of them I've seen are that large or that cheap

[rain escarp]

Only if amazon released their screens as a DIY component....

[lapis jasper]

https://hackaday.io/project/21168-fpga-eink-controller

I have too many projects 😄

[rain escarp]

Too many projects, not enough hours in the day.

And then, work.

[jade loom]

anyone interested in vhdl work ?

for an open source fun project

[vernal ferry]

@jade loom what is VHDL?

@rain escarp what projects are you working on ;O and I hear yah.. I have 4 ongoing uni 😬 projects

[rain escarp]

@vernal ferry Well, in addition to work/sleep/etc -- which the work aspect tends to eat up most of those hours...here are some of the things I'm tinkering around with:

• stair lighting system (motion sensors, LED strips, etc)
• custom-build headboard for a bed (high quality foam, storage, integrated USB & LED lighting that's Alexa-connected)
• getting 3x tiers of ham radio licensing
• adding an infrared remote control to a PlexPi system
• security system for a remote shed (send an alert if someone enters it)

I have rough notes on a magic mirror and "augmented arm" project, but not quite sure what I want from either. The arm is in the same construction as the prosthetic arms, but not meant to assist with a disability...but to add reach, etc.

I also have a DOA feather here that I want to learn enough about electronics to fix it. Not to have the feather, but for the troubleshooting & diagnostic process.

I'm also researching LED wearables for the 4th of July -- I'm thinking something like a top hat, with flex LEDs around with with low-fi fireworks animations.

[vernal ferry]

@rain escarp

• stairs lighting: sounds good, especially at night or early morning when you don't want above head lighting (reminds me of movie theatre stairs)
• custom headboard: more storage!
• why 3x tiers of ham radio licensing?
• security system for remote shed: wifi ? lora?
• magic mirror as in those smart mirror type things?
• augmented arm like samus :}}
• which feather?
• ooh, liek fireworks coming out of a hat?

[rain escarp]

The stair lighting I also want to be able to customize -- different colors for seasons, holidays, etc (green for st. patricks, red/white/blue for 4th of july, etc)

Three tiers of ham radio is so I can play around with radio enabled stuff and be legal doing so :)

Security system -- 100% lora. Probably going to use a trip-wire or a very limited degree motion system. There are a few windows that could be opened into this shed, and sometimes critters get inside. It's a little a distance away from where it's being monitored, so I'd like to limit false alarms.

Yepper, regarding the magic smart mirror. I don't quite know what I personally want from it though, or if a wall-mounted status screen would be better suited for "my needs".

Samus, or Mega Man. I mean, all that time in school for his doctorate, and Wiley uses it for evil. Sheesh. :)

I have the feather 32u4 adalogger -- the one from adabox 001. I have plenty (plenty) of other feathers, but I want to figure it out, ya know? 😃

The fireworks more like a display on a hat. I was thinking something on a jacket -- but it's too flexible, too hard to maintain, and HOT in july.

There was someone on Show & Tell who made their own LED hat, and it got me thinking about LED displays for holidays again.

Plus, the hat could be reused for other events, holidays, MakerFaires, etc -- if it wasn't designed for one specific event. I want to make it so it takes a GIF animation instead of having to manually write out all the animations in code.

low-fi....so probably something like a 160x30 animation?

depending on the matrix of leds of course

[vernal ferry]

@rain escarp exciting :} and lots of NeoPixels! :} I want to try some of the side lit ones too.

yeah re: wearables if it gets too warm or shocking 😄

[rain escarp]

oh, from what i read, you want to keep them 30-40% brightness. 100% it gets toasty. Or roasted. I'm allergic to being on fire, makes my skin get all crispy.

[vernal ferry]

New media lab at uni has an exhibit on wearables with neopixels all over em. :} and im pretty sure all of them use adafruit stuff

[indigo charm]

@lapis jasper thanks! Yeah I'd love to be able to control larger LCD displays... the posibility for digital signage is great. The anoying part of using actual kindles/raspberrypi/android tablets is the need to keep them patched! I love the ESP32 for these things since they're pretty hard to attack if they're on a network, and don't need to be patched.

Got our laser cutter

Made some stuff

[rain escarp]

Glowforge -- does that still need to be internet connected, or did they include a fully disconnected mode yet?

[grave shadow]

@rain escarp it needed to be connected? Glad i didnt go that route..

[unique junco]

@grave shadow are those rotary encoders?

[grave shadow]

@unique junco sure are

[unique junco]

I was planning on making something with those, but I thought they needed to be connected to a breadboard

I was gonna make a rubik's cube core

[grave shadow]

Well. These didnt really get the chance to touch a breadboard

Kinda just went for the pcb

Rofl

[unique junco]

That looks perfect

[grave shadow]

Digikey have a great collection of them, Think i just went for the bulk standard ones afaik.. Also invludes a pushbutton

Includes*

Then some adafruit knobs just fit perfectly

[lapis jasper]

@grave shadow got a link to the slider?

(would they fit on a featherwing ?)

[grave shadow]

@lapis jasper https://www.digikey.com.au/product-detail/en/bourns-inc/PTA3043-2010CIB103/PTA3043-2010CIB103-ND/3781185

[lapis jasper]

thanks!

[grave shadow]

Well. You can make a shield for it i guess? But they dont really like being forced into veroboard

[lapis jasper]

yeah, custom featherwing would be awesome

[grave shadow]

@lapis jasper ive actually forced it before, but you lose the case legs.

[lapis jasper]

neat! the 45mm would fit pretty well on a featherwing

[grave shadow]

Sure would. I have a huzzah myself, great little unit.

[lapis jasper]

I've got an untested design to fit featherwings into a trellis layout

[grave shadow]

Whats the end goal for it?

[lapis jasper]

kinda what you are doing, custom control surfaces

[strong phoenix]

@lapis jasper you can also look for mixing board replacements. though, they may be pricier...

[grave shadow]

awesome ^-^ they're way fun to do

[lapis jasper]

😃

k, time for a little game gear cleanup before dinner. night all!

[grave shadow]

night mate, enjoy~

[signal loom]

@rain escarp needs to be online beacouse all controls are on their website

[rain escarp]

A shame, I just keep thinking at the transient nature of DIY/Maker companies anymore...all the different IoT service providers that shut down access to the hardware you bought without releasing a local server.

[rain escarp]

I'm not implying that Glowforge falls into that category, and they very well may be one of the few that'll stand the tests of time. But whenever I hear "you need our servers for your locally-based hardware, or else you have an expensive paperweight"...it gives me justifiable reason to pause.

[signal loom]

Yeah totally makes sense. But as a intro to laser cutting, I am totally in to it

[warped cobalt]

Antenna?

Is that for phone?

Or wifi?

[fiery plank]

My 2.4GHz stacked Yagi about 22db gain

I made it for my networking class about wifi

[warped cobalt]

Stacked Yagi is new to me, I have seen double Yagi (different bandwiths)

Ah, wifi

Hmmm . . .

[fiery plank]

Also good on the 13cm ham band

[warped cobalt]

Being split, be possible to do 2.4 ghz & 5 ghz?

[fiery plank]

No. It is split because it needs to drive both yagis

[warped cobalt]

I figured ya wanting to drive both, I was just wondering if that is possibility

[fiery plank]

A yagi for 5GHz would be much shorter

[warped cobalt]

True

[fiery plank]

Yagis can only have so many director elements before there is no more benefit

This one i reached the limit

[warped cobalt]

I know, I was thinking of making a “phone repeater”

One of things happen during tornado or hurricane is phone towers being down

[fiery plank]

Ham radio can take care of that

[warped cobalt]

Ham Radio can only do so much, I’ve seen that in person, also most people don’t even know anything about Ham radios, just the phone in their pocket

Anyways, that is cool Yagi

Probably can get pretty good range on it

[fiery plank]

About half a mile. Tested it on a network from the lab

[warped cobalt]

That explains why RC is limited to sight, not range of signal, Hahahahahahaha!

That’s pretty far off

[fiery plank]

We had line of sight though

[warped cobalt]

Ah, does help

Still good bit of distance

[fiery plank]

A very narrow window and buildings on either side and below the window

[warped cobalt]

Aim well, Hahahahahahaha!

[fiery plank]

Yup

I actually had it on the ground pointed toward the window. We were on a hill

Receive % of 78

[warped cobalt]

Enough to be reliable

Pretty awesome signal for that distance

And who needs margin for error?

[fiery plank]

This other guy made a pcb bi-quad yagi recieve % of 100

[warped cobalt]

I hate to fathom if y’all try to find further signal

[fiery plank]

Yeah

This is the 4th or 5th antenna I have made for various freqs

[warped cobalt]

I haven’t made any really

Tho, I do need to get that tape measure 2m Yagi done

[fiery plank]

So I take it your a ham as well?

[warped cobalt]

Hai

Just a little techi

I want to make set up for Fox hunting

[fiery plank]

I am an extra. Still learning though. I made my first hf contact last sunday to California

[warped cobalt]

License is to learn, not mastery

[fiery plank]

Need to get started on my internship. Have a good day
