A rich list of available bootloaders for AVR microcontrollers.

An easy-to-built sound card with TI's PCM2702 chip.

Microchip Technology Inc. today announced the availability of Integration Associates’ EZLink™ Development Kit (Microchip part # TDKEZ915) for $240 on the www.microchipdirect.com e-commerce Web site.

This kit augments the wireless products offered by Microchip, by providing wireless customers an option for easy sub-GHz RF modem development. The EZLink radio module contains an onboard PIC18F2520 8-bit Flash microcontroller and Integration’s IA4421 EZRadio® transceiver.

The Open GPS Tracker is a small device which plugs into a $20 prepaid mobile phone to make a GPS tracker. The Tracker responds to text message commands, detects motion, and sends you its exact position, ready for Google Maps or your mapping software. The Tracker firmware is open source and user-customizable.

The big problem with the parts harvesting is to identify parts. Especially the tiny SMD ones, only with one or two letters on the case.

I've an idea to make the PIC-based Arduino clone: simple, elegant and cheap PIC-based board. So here are some links to Arduino-related materials I've found for future use.

Jesper Hansen's method to connecting DRAM with an AVR microcontroller.

The BitESC is a small electronic speed controller for those little RC cars like the MicroSizer / BitChar-G. It can be used in a small RC plane to have some control over the speed of the motor.

Jesper Hansen's accelerometer named AccelR8 based on Analog Devices' MEMS chip

An infrared (IR) link that provides bi-directional communication between the NXT and the new Power-Functions system, which consists of a battery box, motors, a remote control (an IR transmitter) and an IR receiver that controls the motors.
