The OBDuino is an in-car real-time display of various information, like speed, RPM, instant fuel consumption or average trip fuel consumption as well as others PIDs supported by the car. It reads the data from the car’s OBD-II connector, interfacing it via a MC33290 chip to the Arduino which processes the CAN data and outputs to a 2×16 LCD.

This tutorial will describe a way of controlling an iPod remote, and thus, an easy way of getting some music and sound out of your Arduino project. The remote we used was an unofficial remote I found on the worldwide auction site for around 10 USD, an opto-isolator can be found in your local electronics store. [via]

This project is a frequency standard based on GPS signal that has the advantage of great stability.

Using the GPS Satellite system offers the advantage of very accurate timing and by extension, frequency control. The long term error is to all intents and purposes zero, with time and frequency accuracy being comparable to the international standard. The traditional route is to use a relatively low cost GPS receiver module which outputs a 1 Pulse per second signal (1 PPS) aligned to UTC.

This star is about 35cm across and designed to be displayed indoors in a window. It is based on 18F2620 that has more than enough memory (64K) so the author can add as many features as he want. Check schematic and code on the link below.

Grenadier was trying to make a diode from a piece of silicon carbide that he had laying around but he noticed a faint glow. Investigating this further he found that one of the largest crystals emitted quite a lot of light over an amazingly large area. Using a particular crystal and some pins he managed to make a glowing LED. [via]

This project shows how to build a self-balancing scooter and it is build at the MIT Edgerton Center. The controller is an Arduino board that is driving two DeWalt cordless drills chucked to two 6″ wheels. Additional supporting devices include an Inertial Measurement Unit (IMU) from Sparkfun and two motor drivers from Pololu.  [via]

This article shows how to read NAND flash chips without removing the from the PCB. [via]

NAND flash chips are used in all sorts of electronics for storing information/firmware etc. If you are interested in trying to get the information out to study, then I may have something useful for you. This is how I read the flash chip without removing it from the device.

Not many people know, that regular camera can be used as night vision device because it’s able to take pictures in infra-red spectrum. If scenery will be lighted by source of those rays, for human eyes it will be dark, but camera will be able to take pictures. Learn how to take pictures in IR spectrum in the link below.
