about the circuit
The circuit was inspired and is adapted from "The Nanite 85" (https://cpldcpu.wordpress.com/2014/04/25/the-nanite-85/).
Bill of Materials:
| amount | material |
|---|---|
| 1 | ATtiny85 |
| 2 | Zener Diode 3v6 |
| 2 | Resistor 68 Ohm |
| 1 | Resistor 1.5 kOhm |
| 1 | Capacitor 100n F |
| 1 | LED type PL9823-F5 |
about the firmware
The firmware utilizes 2 projects:
- v-usb (https://github.com/obdev/v-usb) as driver for usb
- micronucleus (https://github.com/micronucleus/micronucleus) as bootloader (optional)
The firmware listens to control transfers and interprets each successful transfer as information for colors.
about the host software
The host software uses libusb (http://libusb.info/) and the pyusb (https://walac.github.io/pyusb/) module to send the neccessary control transfers.
allow users access to device
You can add the following line to /lib/udev/rules.d/991-local.rules and reload with udevadm control --reload-rules to grant everyone write access to all devices from 16c0:05dc:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05dc", MODE="0666"
