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. * 405nm (Blue) Laser

My Bicycle I bought the bike from George Vettor Cycle & Sport in Guelph. Plans * Design bracket for GPS logger and battery * Design LED lighting system * One idea is for a POV style digital readout for velocity, but I don't bike at night so much anymore... Lights

CarouselPi - A Kodak Carousel Slide Scanner

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.

7-segment display module

Anonymous (anonymous@undisclosed.example.com) — 2014-11-13T22:37:16+00:00

7-segment display module [Working Display] Arduino library available on Github This was one of my first doublesided and surfacemount boards. I made this board using Eagle for layout and then I used BatchPCB to manufacture the board. The board operates correctly, however, if I were to revise it, I would use a larger SMT resistor than the 0402 size. The board will be controlled via I2C from a PIC microcontroller, initially for the pressure sensor and later for other projects.
