Railroad Grade Crossing Signal Controller
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 […]
Got Wireless? Modify a Simple 12VDC Wireless Remote Control for 5VDC Operation
Adding a remote control switch to nearly any project is easy with these small keyfob-based RC relays. They are very inexpensive (<$20) and offer such options as MOMENTARY and TOGGLE operation as well as multiple relay channels to control. However, from what I found, these units require 12VDC to operate properly. This article explains how […]
