Dual interfacial H-bonding-enhanced deep-blue hybrid copper–iodide LEDs
I have to buy a new #flashlight and because #LEDs are so powerful and require a smaller form factor and less space for batteries most of what I see are small and compact BUT I like a #workshop flashlight with some #heft to it and I know it's just #psychological. Am I #weird or just a #boomer.
120 NeoPixel patio #LEDs (two strings of 60) powered by a Pico 2w on a mobile phone wall wart.
Not as bright as l'd like. Will distribute power but the simple #CircuitPython animations look cool. Any good recs of brighter NeoPixels to spread out on a field for an animated matrix-style installation?

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
@3dprinting And of course there will be LEDs for illumination, and an ESPHome (or maybe two) to monitor and control it.

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.

@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:
