This project uses IRLB8721PbF MOSFETS. These particular devices are good for the Arduino because the base current required to fully open the gate is less than 5v. I chose to use a power supply case to house this project. The built in fan will supply plenty of airflow over the heatsinks attached to the MOSFET’s. […]

These directions were adapted from alan-parekh.com. The IR Jammer project is microcontroller-based; what this means is there is a small self-contained computer that controls the unit. The IR Jammer will cause most infrared remote controls to stop working. This means that you could prevent someone from changing the TV channel or adjusting the volume on […]

LED throwies are cheery glow-dots you can make in seconds from simple components and stick to any ferro-magnetic surface. But that’s just the beginning — here’s how to hack and modify them. First make a basic LED throwie, and chain them up into big throwie “bugs.” Then learn to hack the throwie with an On-Off […]

The Mintronics: Menta is a unique Arduino-compatible microcontroller kit. It features a handy, on-board prototyping space and is specifically designed to use the included mint tin as an enclosure! This makes it perfect for logging applications and on-the-go development. The prototyping area is perfectly sized for one of our mini breadboards (not included) so you […]
