My DIY Digispark

In honor of all the Attiny85 + V-USB microcontroller boards and their clones, I have built my own...

It is programmed with the micronucleus bootloader, so it is compatible with the Digispark version of the IDE. The most expensive part was the time in putting it together... the parts themselves were under $3! :open_mouth:

Anyway, it has been a challenge using this subset of full arduino... but the compatibility is amazingly good. I often use my full Atmega board to develop and debug apps for later loading onto this board. Mostly... it just works.
