I want to build a simple USB controlled (on/off, maybe change

motor? what to power? those cheap $2 ones cant really be beat, you can solder the usb cable to it or solder a connector to it.

I'm happy if I can just turn it on and off through a script or something. I want to use it as a physical notifier for random stuff.

Would this work? http://www.ebay.de/itm/Mini-Digispark-Kickstarter-ATTINY85-Micro-USB-Development-Board-for-Arduino-/331453927604?hash=item4d2c3190b4:g:FL4AAOSwa39UvHm4

>just turn it on and off
If you can script the DTR output pin this is all you would need.

You have to use transistor or relay to power a motor.

Unless its a really really tiny motor. I think attiny85 can drive a total of 200 ma, but it has no limiting circuitry, it will simply blow itself out if you exceed it.

Get something called an h bridge and connect it to your digispark, now you can drive the motor in both directions.

The power would be supplied externally via battery.

1.5$ arduino pro mini/nano from china
I use em all the time for prototypes when i dont wanna write machine languages for cheaper 8 bit cpus
