Anyway I cant believe how simple is the schematic and how powerfull is this little Attiny85. Maybe for you guys, who are in the AVR world for longer time this is normal but for me its quite a surprise.
To sweeten the pot, most of the Trinket & Digispark library will work, too. With Diguspark, the fuse setting is one===>way... You loose the reset but gain an output pin that can be pwm. With Trinket, you maintain the reset button but the upload is a bit flakey ... Of course, you do not have to use a boot loader with Trinket, but you must with Digispark.
