Fresh hacks every day
The [Libelium] team wanted to help people in Japan measure radiation in their surroundings following the nuclear accident in Fukushima. Because of the affordability and seeming ubiquity of the Arduino platform, they have been hard at work this last month trying to get their Geiger counter sensor board for an Arduino out the door. We think they’ve done a remarkable … Read the rest

[Utpal Solanki] wanted to do some text chatting from the comfort of the couch. He built this wireless chat client that he calls Chatbox using a microcontroller, a character LCD screen, and a keypad that he built himself.
The device communicates via an Infrared emitter and receiver. It pairs up with an Arduino using an IR shield that [Utpal] built. … Read the rest
[Colin] wanted a way to reliably control an Arduino via ham radio. One of the easiest methods of automated radio control makes use of Dual-Tone Multi-Frequency signalling. To those who aren’t into amatuer radio you probably recognized DTMF as the touch-tone system for telephone communications. [Colin] built a shield that has an audio input and can decode DTMF signals.… Read the rest
[Sean] used his old webcam to assemble a closed circuit television feed for his home. He already had a server up and running, so this was just a matter of connecting a camera and setting up the software. He wasn’t satisfied by only having a live feed, so he decided to add a few more features to the system.… Read the rest
