Thinking about a simple stripe with single controllable LEDs. To light up the room here a bit.

• ideally:
  • no extra power supply (limits me to a handful LEDs.. but that's enough for a start)
  • USB controllable, or wlan/bluetooth
• “usb argb led” search should bring up USB controllable LEDs sec
• project for a few LEDs, directly connectable to a Raspi, no extra power
• https://github.com/adafruit/Adafruit_CircuitPython_NeoPixel - lib for NeoPixel products - how much extra hardware required? Easy to setup?
• Matter controllable stripe?
• https://github.com/Makuna/NeoPixelBus
• hyperhdr is a project to control stripes for ambient light behind monitors. https://www.hyperhdr.eu/2023/02/ultimate-guide-on-how-to-build-led.html has a description of their hardware.
• WLED board
  • board with ESP-chip, ready to just get LEDs and power supply connected and can then be used
  • project, amazon
• soldering iron recommendations:
  • https://pine64eu.com/product/pinecil-smart-mini-portable-soldering-iron/
  • CROSS MARS TS80P Lötkolben Type USB-C
• power supply sizing:
  • 0.3W/LED. USB3 allows 4.5W, so up to ~15 LEDs might be ok
  • 1m/18W @60 LED/m
  • “neopixel led strip”
• LEDs
  • WS2812b, or WS2813, or SK6812, or SK6813, or Adafruit strip for start
  • 8×32 matrix?
