Watch Winder

I love the original design.

This is a small remix of it. It uses the slim design and I also made a custom cutout for USB Micro connector in the base. I went different way for mounting the motor. I designed slots for square M3 nuts and used M3 screws instead of glue.

I am uploading hex file for the ATTiny85 in case someone would like to flash the chip with it.


Here are parts I sourced over the net:

I glued the USB Micro board in the slot of the base. Everything else is described in Simo_Dax's post on Instructables:

ATTiny85 can be flashed on Windows/Linux/Mac with avrdude. There are many tutorials on the web. Arduino Uno can be used as programmer.
