This project is a 2 channels amp meter. Those channels are completely isolated up to 2000 volts.It provides auto detection for AC or DC current. The main part of this project is the current sensor ZMC10 a cool DIP 14, which supports up to 10 A. The current is measured inside by hall effect sensor and display data using a graphic LCD of the read current and max peek value, DC or AC [more]

Its a simple little box that makes wiring up an 8 x 8 LED Matrix easy. It uses the MAX7219 (or 7221) LED driver chip from Maxim and uses the Matrix library in the Arduino library.[more]

Self-Propelled Toy Car based on PICnome. Shunichi Yamamoto writes:
PICnome is the open-source hardware. So this is not business. my primary job is to study and develop the hardware and software based on chaos and complex systems.

Pinguino is an open source set of tools. The goal of this project is to build a real USB development board. Due to the many applications designed with Arduino and based on an ATMEL microcontroller, the idea was to build a compatible board and language with a real USB microcontroller, the PIC18F2550.This Pinguino or Arduino-like board based on a PIC Microcontroller. The goal of this project is to build an integrated IDE easy to use on LINUX, WINDOWS and MAC OS X. Arduino is a powerful tool with some defaults. One of its inconveniences are a no native USB interface on the chip and its code length.
The IDE of Pinguino is built with Python. An integrated preprocessor translates specific Arduino instructions directly into C. This preprocessor reduces the code length and the execution speed. Pinguino hardware is based on a PIC18F2550. This chip has an integrated native USB module and an UART for serial link.[more]
