Phage Band

The phage band is a small flexible circuit board that's designed to be soldered in a loop of WS2812 RGB LEDs.

The board has the following features:

Powered off of +5V via microUSB header
ATTiny85 for pre-programmed light patterns
A single pushbutton to control operation mode
If both ends of the WS2812 ribbon is soldered to the board, the ATTiny85 can automatically detect the length of the LED string
Microphone and pre-amp with gain control selection (aka "robot heart mode")
Flex circuit construction
- programming header and microphone section can be sheared off with scissors if they are not needed for a more compact driver circuit
- Steel stiffener plate under ribbon solder point and microUSB header for mechanical robustness

Below are renderings of how the board will look:
