Trandi posted a step by step guide of his DIY wireless doorbell build: So this was the perfect pretext for a small electronics project, centred around the idea of a simple voltmeter that would notify us when the voltage goes below a safe level. This would most easily be done with a small micro controller […]

Tweeting cat door
Let your cats be part of the social media explosion! The tweeting cat door project tweets a message every time a cat passes through the door. The project is based around the Electric Imp which is a Cortex M3 processor and a WiFi transmitter packed into an SD card. A breakout board for the Electric […]
Guitar Hero wireless foot pedal talking to the Arduino
Tom wanted to operate the panning of his webcam via foot pedal. The solution he came up with was to use the old Guitar Hero wireless pedals. He reverse engendered the PlayStation protocol to allow his Arduino to communicate with the pedals. What he ended up with were 2 wireless pedals with linear position reporting. […]
PlayStation 2 controller connected over a RFM12 wireless module
Dustin connected his PlayStation 2 to a PC wirelessly using two RFM12 modules to make the link. On both sides AVRs with Arduino bootloaders drive the wireless modules. All the source code for this project is available.
Wireless home energy monitor
Here is a project that allows you to keep track of your household power consumption over a wireless connection. Jone’s energy monitor project counts electricity meter‘s indicator pulses, which the electrical distribution company uses to bill you. Once it reads 5 minutes worth of consumption data, it is broadcast to a web server over a […]
Glass Block LED Matrix, controlled outdoors via tablet
Here is a video from Hive 13 that shows how an Android tablet is used to control a glass block LED matrix via a wireless connection. After installing a LED matrix behind a glass block wall in their bathroom, hackers at Hive 13 are figuring out a way to control them. After some initial struggles […]
nRF24LE1 low power single chip wireless data
The nRF24LE1 is a single chip radio that can be used with a microcontroller for low power wireless stuff. It has lots of extras like an ultra low power analog comparator for voltage level system wake-up. Nordic Semiconductor provides an RF protocol stack and applications for microcontrollers. Via MDFLY.
