1-key USB keyboard
5. December 2008 - 19:54 — adminThe idea for a 1-key keyboard comes from the need as an interaction designer to make “cheap, quick and dirty prototypes.” When creating a quick screen-based demo in e.g. Adobe Flash, a common way of quickly prototyping physical actions is to assign actions to certain key presses on a keyboard.
GLCD video emulator
4. December 2008 - 23:34 — adminA GLCD emulator - takes commands for common GLCD and places output to the TV.
AVR and 1-Wire interface
4. December 2008 - 14:25 — adminDallas Semiconductor (Maxim) produces a family of devices that are controlled through a proprietary 1-wire interface. On a 1-wire network, a single "master" device communicates with one or more 1-wire "slave" devices over a single data line, which can also be used to provide power to the slave devices. How to connect such devices to Arduino?
Stealth USB CapsLocker
3. December 2008 - 21:47 — adminJust a joke for April Fool's Day, but I believe it can be used in some other way.
FemtoOS for AVRs
2. December 2008 - 15:28 — adminThe Femto OS is a very concise portable preemptive operating system (RTOS) for embedded devices with minimal ram and flash, say 2KB .. 16KB flash and 128 .. 1024 bytes ram.
ATMega SID emulator
26. November 2008 - 21:40 — adminThis program tries to emulate the sound chip SID of the famous historical C64 Commodore computer (SID = Sound Interface Device). The SID emulator includes all registers of the original SID, only minor functions are not implemented yet.
True Random Number Generator
25. November 2008 - 21:21 — adminTrue random number generator, generated by AVR-based hardware (not a computed pseudorandom numbers).
A lot of reading
25. November 2008 - 20:27 — adminOld magazines, old OS, old games source code, all's old today.
