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 [[https://forums.raspberrypi.com/viewtopic.php?t=336776|sec]]
  * [[https://montessorimuddle.org/2021/02/17/led-light-strip-with-pi-zero/|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?

  * 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

  * 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
    * 8x32 matrix?
