This Instructable will show you how to modify an Altoids tin for a wireless 2×16 character display. Using an Altoids tin was inspired by the need to have a small yet protective enclosure for a pair of Xbee modules recently bought from Sparkfun. I purchased the Xbee Pro modules with external antenna for the extended range the setup provides (useful for […]

This energy monitoring transmitter, known as emonTx, is an Atmega328-based small wireless energy monitoring node. It also fully compatible with Arduino IDE. EmonTx is designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. The design is based on the JeeNodeV5 by Jean-Claude Wippler and uses 2x AA batteries or 5V USB as

A simple signal generator which produces sine waves (or any waveform really) at audio frequencies using DDS and is controlled a USB serial connection. Only 2 chips are used in this circuit. The AVRATmega88 which produces the signal, and an FT232R for the USB interface. While a computer is required to control the varying frequency of

The game Mastermind has been around a long time, and I remember getting a board version with colored pegs when I was a kid. I love this game, as it is solvable simply by pure logic. One player (or a computer/microcontroller) chooses a sequence of colors from a pool of available colors and then the other player
