405nm Laser Diode
Blue, Violet, almost Ultraviolet really. I made a driver board and just need to finish the heatsink and mount it in a case. I bought a translucent blue project box from Hammond that I'll be mounting the laser in.

CarouselPi - A Kodak Carousel Slide Scanner
I'm converting a Carousel slide projector into an automated slide scanner using a Raspberry Pi with a camera module. My main goal is the cataloguing of the slide trays and indexing with the use of barcode stickers on each carousel. I intend to have the images indexed so that I can easilt find a specific slide and scan it in with a professional scanner.text/html2016-12-11T20:47:18+00:00Anonymous (anonymous@undisclosed.example.com)C.H.I.P Computer
