Rik Magers made his own version of the Commodore 1541 disk drive. He started with a uIEC from Jim Brain Designs. The uIEC has JiffyDOS and the ability to store up to 32GB. Rik got hold of a small plastic box that looks similar to a real 1541. After cutting, tweaking and several tubes of glue, he had a mini version of the 1541 including working LEDs on the front.
