Mayke [5/31] - Making a shiny 
blinkenlight bling bag that reacts to the sounds around it
DIY #mothtrap proof-of-concept.
Yes, those are #ultraviolet #LEDs.
Yes, that’s a light sensor on the right.
No, I’m not happy with the #leadacid #battery but they’re cheap, reliable and ideal for these experiments.
Now to find an enclosure…

The WOW Festival (http://wowfestival.org) is happening at UCSD this weekend! I did some of the LED lighting for ODDISEA: A Puppet Procession, by Animal Cracker Conspiracy. They are one of the roaming free events, starting at 7:30pm on April 24, 25, and 26th. #art #sandiego #LEDs
Just playing Super Mario All Stars on an RGB matrix panel as you do.
To keep things together better, I 3D printed a bracket in two pieces, the subject of a work in progress playground note: https://adafruit-playground.com/u/jepler/pages/3d-printed-bracket-for-4-64x64-2mm-rgb-matrix-panels
This is using a 3rd party breakout board with 3 HUB75 connectors. I recently added the ability to drive up to 3 connectors to Adafruit Piomatter, as well as temporal dithering.
In this specific interest, I'm using 2 connectors to drive a total of 4 64x64 panels. --num-planes=6 --num-temporal-planes=2 means I'm getting effective 18 bit color, albeit with the least significant 2 bits being shown on alternate refreshes, creating a tiny amount of 44Hz color shimmer.
All these "go faster" tricks together give me about 88Hz refresh rate on the panel, despite that we're still limited to about 10MB/s of data between the PI's main CPU and the PIO peripheral that's acting as the LED controller.
@3dprinting And of course there will be LEDs for illumination, and an ESPHome (or maybe two) to monitor and control it.

Yet another MIDI monitor on yet another small, neat, microcontroller - this one the Waveshare RP2040 Matrix which has a great little 5x5 programmable LED matrix onboard.
And no, I'm not bored of these things yet :)

Why does every piece of #electronics now have to have super bright #blue #LEDs?
Annoying and painful on the eyes.
Finished this art piece for my office!
The base for this piece is a cork board. I painted the frame, covered the cork in fabric, added a string of WS2812 LEDs controlled by a Pixelblaze V3 Standard LED controller, and then finished it up with some mirrors and flowers.
This art took 23 calendar days to finish, but only 7 of those are days where I actually made progress on this project. The other 16 days were focused on other events and projects in my life.
The materials cost:
$39 USD for Pixelblaze
$35 USD for the LEDs
$20 CAD for the fabric
$10 CAD for the mirrors
$ 6 CAD for the fake flowers
$15 CAD paint
$ 5 staples
+ cost of tools and miscellaneous supplies
If you want/need a 32x16 RGB pixel panel and some alkaline batteries, the Mc2 Pixel Purse is on discount at amazon again. $8.99 at the time of writing this. I've deconstructed several for the panels, and at this price it's worth it.

#maker #LEDs #microcontrollers
I am on a personal quest to fix a problem which has plagued #Hanukkah since the dawn of time.
And by "dawn of time" I mean since #LEDs were invented.
There are many LED menorahs, but they're all-in-one things, with the LED "candles" built into the #menorah. I have one, and it's fine, but I also kinda hate it. What I *really* want is LED candles which I can stick in whatever menorah I want. A BYOM(enorah) solution.
I found some incredibly misleading ones on Amazon, which are photoshopped to look like they fit in a typical menorah, but are in fact GIANT AAA battery powered candles which are 4x bigger than a typical menorah would accommodate.
Despite the absurdly prescriptive nature of most #Jewish traditions, there is no mandate for the size of a Hanukkah candle... but most of them are about 9mm diameter.
So, somewhat in a similar vein to @TechConnectify 's quest for the perfect Xmas lights, I am iterating on 3D printing my own LED Hanukkah candles. Or more specifically, I am printing "holders" for some of these - https://a.co/d/iaM59TD
I'm up to my 9th revision so far... I think I'm honing in on a good solution, but with each print I manage to discover some new innovation or problem I want to address. 
Pt. 2 of the @alexlynd #DevKitty #hardware #security kit workshop goes live in ~20! We'll be programming #LEDs & custom #IoT payloads 
Plus, tune into our Hackster.io Holidays Finale next Tuesday to win a kit! https://events.hackster.io/hacksterholidays

@thomasareed @CAWguy @Viss Granted, the solution is to use #LEDs in #bulbs and mandate properly adjusted and adjustable lights that don't blind people.
But yeah, to me it seems as if too many people constantly use highbeams all the time and in modern #superUselessVehicles one doesn't notice due to automatically & electrically dimmed mirrors and the fact that said cars nowadays have their front lights above the height of the rear window of a regular compact hatchback...
The #Enshittification of the #car is a major problem and also a reason most modern cars are now €50k+ MSRP and it's impossible to find anything that is legally a car for under €10k and extremely hard for under €25k...
Here they are running at what I think is 1/2 of their original intended running voltage, which means they’ll run FOREVER
almost never is it the LEDs that burn out when an LED light bulb burns out.
save those discs while you can, the light quality is also good and so bright and you can run singles or pairs at low voltage for stupid brightnesses, they’re great
A thread of some of my LED projects, for posterity.
One of my favourites, sound reactive LED rollerskates.
Running WLED on a ESP8266 D1 mini pro on each skate (don't ask, one of my first projects). Which are controlled by an exterior ESP32 with a microphone attached.
The left pair were for my friend for a performance we did.
Had an hour before going to a show last night so I slapped some electronics on a hat. I'm heckin stoked on the effect.
Interestingly, I have to place my 18650 battery at the front inside of the hat because the halo tilt doesn't allow for it at the back. *Gestures at physics*
I'm using a Pixelblaze LED controller from @wizard (wirelessly controlled on my iPad), and micro COB LEDs that are in my LED guide:

@fuchsiii There are some @adafruit #NeoPixel-style #LEDs with #Microcontroller|s...

I finished that blog post I was supposed to publish in 2019... Behold, the World's Largest LED Cube!
Here's my badge #SAO for this year's #HackadaySupercon
It has a few button selectable modes, but the default one follows the state of the characters in Pac-Man 's attract mode.
It's also commandable over I2C, so you can set the LEDs up yourself if you like.
Thanks to @simenzhor for the help around the obscure but cheap microcontroller.
I will have some at Supercon and may throw some up on Tindie.
