Excellent resource – A small collection of electronic circuits for the hobbyist or student. Site includes over 100 circuit diagrams, links to related sites, commercial kits and projects, newsgroups and educational areas. Most of the circuits can be built with common components available from Radio Shack or salvaged from scrap electronic equipment. Most all of the circuits have been built and tested and believed to perform as described, however possible mistakes may be found. Link.

$3,000, but it’s tempting…E Ink’s Active Matrix Electronic Paper Display (EPD) Prototyping Kit is designed for product designers, engineers and technologists who want hands-on access to a high-resolution paper-like display. The kit includes a production sample of a 6″ SVGA (800 X 600) active matrix display made using E Ink Imaging Film, along with all of the hardware and software necessary to produce a fully functional portable device. The prototyping kit is based around the Gumstix single-board computer, which combines a 400 MHz Intel XScale® PXA255 processor with a Bluetooth transceiver, USB, a serial port and an MMC card reader. For mobile prototyping, the kit also includes two Li-ion batteries with a total capacity of over 4000 mW-h, and an integrated battery charger. [via] Link.
