**Components:** --------------------- * 2x 2x5mm screws * 1x 2.5x20mm screw * 1x 12x12x3mm button with cap * ESP-01s + [WLED firmware](https://github.com/Aircoookie/WLED/releases) * Charger (TC4056A) + DC-DC boost controller * Custom board with soldered AMS1117-3.3v (ESP power and connections board. I cut from prototype board) * 3x15cm LED strip (WS2812b) * 1x 21700 or 18650 battery * Soldering iron + straight hands ^_^ **WLED tuning:** --------------------- Add presets ("API Command"): * "`T=2`" - Power switch * "`P1=1&P2=31&PL=~-`" - Previous preset * "`P1=1&P2=31&PL=~`" - Next preset Note: P1 - First preset, P2 - last (Count of presets). Go to Config - Time&Macros - Button actions And set this 3 presets to any button actions you like. In "segments" - add 3 segments, 9 leds per segment. "Reverse direction" for 2nd segment (Or 1 and 3) for better animations. WARNING: ==================== 1. On full bright - LEDs can generate too much heat, possible to deform holder. Use ABS plastic or reduce brightness. 2. DC-DC converter based on TP4056A chip. This chip does not have uder-voltage protection, so possible to damage battery (voltage drop upto 2.7v - then ESP may glitch and/or you can see some light glitches) **TODO: Replace DC-DC to more reliable and functional module.**
