Adafruit Trinket compatible µVolume USB Media Control PCB – with NeoPixel ring! via Hack-a-day. Rupert writes –

Back in August, you may have read my article regarding the AVR based  Attiny2313/ Attiny84/ Attiny85 USB Volume Controls.

The article appears to be pretty popular on various websites, including a nice mention on the Adafruit Blog.

With the release of the Adafruit Trinket (Attiny85 based) a tutorial is now available on the great Adafruit Learning System for a Trinket USB volume control example.

After Purchasing a Trinket to experiment with and Adafruit having a great mentality for Open Source Hardware, I decided to modify my own Attiny85 volume control PCB to make it compatible with the Trinkets 5Volt firmware (flash_me_hv_5volt.hex)! (which is Arduino compatible) This gives access to direct programming without the need for a separate programmer from the Arduino IDE. Its also nice to support the hard work done at Adafruit  by purchasing one of their Trinkets.

Very cool project!
