Wow, check out this homebrewed radio you can make in your spare time!

The first time I tried this, it didn’t work. It was frustrating, but I just went through my materials, blued the razor blade and it worked. The second time I tried to get it to work, I couldn’t get a station, I just got buzz. I played with everything and finally figured out that the ground connection wasn’t very good. When I fixed that, I was able to hear sports talk radio! One of the interesting things is

DIY IR PaintRemover

Posted on September 12, 2007 by max

I just painted my new apartment with some orange, more orange, and lavender paint. Here’s a great way you can make a IR PaintRemover! (good find, Phillip!)
