Infrared diodes and detectors make things fun and magical. We are used to touching or flipping a switch to turn on lights. A simple transistor circuit with an infrared detector and the lights change with a wave of your finger. My circuit boards are simple and all of the parts to run the detector, transistor […]

You can use infrared diodes to light up your people when you get close to them. When your transmitter activates their detector their lights light up, and their transmitter lights up yours. When someone touches your magic spot (your detector) your spot lights up and their thing lights up. It is simple and easy to […]

This project guide explains how to build an operating railroad grade crossing signal controller (GCSC) for controlling a simulated railroad crossing signal that has working flashing lamps and striking bell. Just like the real thing! This board was also designed with hacking in mind. Due to the on-board 5 VDC power supply and extensive breakout […]

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. […]
