Spinning LED

This has surely been seen by everyone, but is a neat DIY project nonetheless. I bring this only because I made this a long time ago, as a part of one of my labs in undergrad at Auburn University, and thought it was a really neat project. The way this works, is you have an [...]

Altoids pocket amplifier

This project was featured on Makezine, only they did not show the article. It was just the Flickr pictures of it (at least that is the project I saw). This is a neat project to make, and has several applications. First it could just be to power your headphones, or it could power a small [...]

Rectifier (AC to DC)

There are times that in a project you may want to tell the difference between various voltages. The best way to do this is to get an analog to digital converter. This will let you convert any sort of varying voltage into a digital binary number. If you get an 8 bit A/D converter, you [...]

Build your own Radio

If you look down a few articles and see the laser radio, you may wonder how can you transmit a radio signal through light? Well in reality, you are not sending a radio signal, because that is via an electromagnetic wave, but you are modulating the light. You are actually amplitude modulating the light (AM), [...]

1-watt amplifier

There is a lot of need in electronic projects for a good amplifier. Here is a small 1 watt amplifier made with simple resistors and transistors. I try to remember back to my electrical engineering days of how to do this, but can’t remember. This is a good website that tells how to use a [...]

Build a Gps

Here is a how-to project for making your own GPS. This guy takes a LCD from a cell phone, and a GPS unit, and makes everything he needs for his own personal GPS. It seems hard, but what a challenge. [Link]

Transmit radio signal with laser

This is a how to project on transmitting audio through a laser. I remember some electrical engineering friends of mine doing this same thing. I have always wondered how it was done, but now, I see it is pretty easy. I might have to make my own version of this. Of course, I would not [...]
