Commercial Geiger counters can cost hundreds of dollars. Build your own at a fraction of the price! This easy-to-solder kit can be built in an evening and it works just like you think it would; clicking and blinking in the presence of radiation. Just follow the instructions here to build it and use it. Your […]
You may have the most beautiful picture, diploma, or award that’s hiding in the dark. Now you can illuminate it with the LED LilyPad Frame, and bring it to life. Here are the materials you will need to build this beautiful project:
I used the time it took to get both my internet and my computer fixed to create my largest project so far.
Here is a video summarizing the project
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. […]
