Earlier this year I have bought on the flea market a used car GPS system, an Amstrad gp1000. (Un)fortunately it was so badly damaged, that it could not be repaired, so I thought I would reuse some parts from it. Then came the idea of building a portable GPS logger system. The receiver runs perfectly …
Gas boilers are usually equipped with a simple sort of controlling element, but they regulate the amount of heating by measuring the water temperature inside the system. Without a proper room thermostat, that works on the principle of measuring the air temperature, is actually a waste of energy. This project offers a very simple and …
Have you ever heard of TFT LCD screens? They are great ways to display information from your Arduino, or display pictures. The Arduino team just released an official TFT LCD screen with their new Robot at Maker Faire 2013. It’s very easy to get started with!! This tutorial will show you how to get the …

Analog Device’s AD8232 is an integrated signal conditioning block for ECG and other bio potential measurement applications. It is designed to extract, amplify, and filter small bio potential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This design allows for an ultralow power analog-to-digital converter or …
Overview The Arduino OBDCAN Shield connects Arduino board to CAN OBD-II compliant car, light truck, or motorcycle. ISO15765-4 (CAN) protocol Arduino R3 form factor Stacking headers for expansion and connection to LCD Joystick control for menu navigation Provides operating voltage for the Arduino board from OBD connector Serial port operating voltage either 3.3V or 5V, …
Introduction Now and again there’s a need to expand the I/O capabilities of your chosen micro controller, and instead of upgrading you can often use external parts to help solve the problem. One example of this is the 74HC4067 16-channel analog multiplexer demultiplexer. That’s a mouthful – however in simple form it’s an IC that can …
A little bigger than a postage stamp, the Simple Servo Tester lets you control two digital or analog servos without using a transmitter or receiver, just plug in your battery pack to start testing. Use it to check your servos before installing them into your models or to center your servos when setting up linkages. …
This wearable LED heart simulator pendant was inspired by my work as a cardiovascular surgical nurse as well as my love of electronics. It simulates the electrical activity of 17 different rhythms and when paired with the heart backplane, it becomes an audio and pulse simulator as well. It is not so much a kit …
You’ll be the talk of the town when you wear this obnoxious, oversized, completely impractical wristwatch. Display your favourite foul language, song lyrics, prime numbers, etc. Inspired by the Microreader kit, I decided to make a giant watch using similar sixteen segment displays. Twelve hours later, I came out of my masochistic fugue and stopped …
The TS3004 is a single-supply, timer IC fully specified to operate over a supply voltage range of 1.55V to 5.25V while consuming 1.9μA supply current. Requiring only a resistor to set the base output frequency (or output period) at 25kHz (or 40µs) with a 50% duty cycle, the TS3004 timer/oscillator is compact, easy-to-use, and versatile. …
