The phage band is a small flexible circuit board that's designed to be soldered in a loop of WS2812 RGB LEDs. It is about the size of your thumb.
It's meant to be a convenient and compact way to make a ribbon of LEDs do something interesting.
The board has the following features:
- Powered off of +5V via microUSB header (for use with battery packs commonly used to charge cell phones)
- 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:
