The guys over thetransistor.com design an arduino clone that requires the minimum parts needed to build the arduino plarform. It is designed to be build on permanent circuits or on a breadboard. Schematic is included on the link below.

Tim at thetransistor.com build his own homemade Nixie Display using old parts. He used a DC to DC converter to build up the high voltages and an arduino to control the nixie tubes. [via]

SCANALOGIC 2 is a reliable, compact and easy to use logic analyzer and signal generator.
Like it’s early predecessor, SCANALOGIC 2 is a 4-channels logic analyzer. Being one of the rare 4 channels logic analyzer we are aware of, it’s a perfect candidate for being one of the most easy to use devices available. It is specially targeted to projects and studies involving serial comunications. Never the less, scanalogic can also be used for many applications like:
Serial protocols decoding and analyis (like UART, SPI, I2C, etc…)
Logic changes on signal lines, and/or noize monitoring and analysis
Analysis of PWM signals, their frequencies and envelopes (Using the FFT feature)

This is a new design for a universal gear indicator that can be fitted to any motorcycle as an aftermarket accessory. Its main advantage is that its operation depends entirely on the gear shift lever movement, instead of connecting to speedometer and tachometer sensors (found in expensive commercial devices), which are rarely available in older motorcycles. It consists of a main circuit including a 7‑segment LED indicator, two Hall sensors that are attached to the motorcycle frame, and a small magnet placed on the gear shift lever.

We are happy to introduce a new electronics community called Electronics-Talk.com. This new community aims to become the place where electronic hobbyists around the earth meet and exchange ideas and thoughts. Please take some time to navigate throught the community and feel free to post your topic on the corresponding category.
Community software used is IP.Board 3, which is state of the art of forum software so that discussions can run smoothly. Also many new features are introduced.
Feel free to become part of this new effort to build a quality place for electronics hobbyists.
