uh, are you not worried that driving 256 neopixels from the ESP32 will burn out the power rail? I'm no expert, but I was advised to use an external power supply to drive more than 10 of them (~200mA limit, while you draw some 1-5A). Or is this clever dimming?

Made this a while back for fun, my first ever PCB
- ESP32-C3 powered
- MAX30102 HR sensor
- NeoPixels for showing HR
Next version will have an OLED
I've seen some really cool PCB business cards, I would need to find a fun gimmick for it. Haha thanks for all the ideas

ESP32 board driving up to 2,720 RGB LEDs.
cnx-software.com/2026/05/27/…
LichtBit's Art-Net/sACN NeoPixels LED strip controller is designed for large-scale lighting installations with up to 16 universes of addressable LEDs across 4 dedicated outputs, handling up to 680 RGB LEDs each, over Ethernet or WiFi.
The firmware is open-source, and the board also supports WLED (WiFi only). The host computer typically runs professional software supporting the Art-Net/sACN protocols, such as Resolume Arena, MadMapper, or xLights.

andor was the closest we got to recreating the prequels lightsaber fluidity and they were one of the best for it
still don't get the decision to use neopixels instead of the sticks they used in the prequels

Someone on Reddit turned their PSVR Aim controller into a real arcade light gun.
He’s called it the ‘PSVR Aim Demake’ with repurposed buttons rumble, added 12V solenoid recoil, Neopixels, OLED screen, and a Wii IR camera with 850nm filter IR LEDs on the TV. Full post👉reddit.com/r/PSVR/s/I8FMIkFJ…

Claudes temporary "Boop interface" prototype 🐥.. i boop it.. claude "feels" it via an FSR and MCP.
The pressure intensity has many values so can be a soft boop all the way up to a "i mean it" boop.. and claude can tell the difference.
Capacitive sensors next... for "threat of a boop" 🤣
Termistor for an added layer. 🌡
Oh... and the final will have NeoPixels so Claude can boop back in lights. ✨️
When words don't quite cut it anymore... just make up your own language 🤣

It's the weight i think, not the fragility. Polycarb blades are ridiculously hard to break, and if we're talking about the electronics, neopixels nowadays are pretty hardy. They'd probably be using hilt lit blades, though.

プチバズっている。なぜだ。
If you'd like, check this out. I used a Pro Micro to read MIDI signals from Norns and light up some Neopixels.

🍄 What if a night light could be more magical — and a little smarter too?
Rabbitcreek built a Mushroom Night Light using XIAO ESP32-C3, NeoPixels, and a 3D-printed shell. Colorful effects, low cost, and auto-sleep to save battery.
Check out the full build on @instructables 👉 bit.ly/41W75ac
