Home theater PCs are becoming more and more popular these days. It’s a great way to watch TV shows without being restricted to the schedule that the networks set for you.

Many people might find it difficult to justify the cost to purchase another computer, just for media, when their existing one can play it just fine, but with this guide, you can get a full setup for $200, even less if you search for deals. This guide will set you up with a 1.2GHz Celeron 220 processor, 1GB DDR2 RAM, 250GB SATA hard drive and a small 90W power supply, all in a small form factor.

Cheap DIY Metal Detector
In this video, RazorG shows us how to make a check metal detector using nothing but an old AM radio, some tape, and a calculator. What you want to do, is to turn the volume up to max on the radio and tune it to the high end of the frequency but not directly on a broadcast station as you want to hear static. Once you have done that, position the calculator on the back of it while both devices are turned on. Adjust the position of the calculator until you hear a tone, and then securely tape them together so it can’t move.
That’s all you need to do, you now have a simple DIY metal detector. RazorG says this works because the loud tone coming from the radio is the calculator’s circuit board which produces a radio frequency signal. The radio waves from the calculator, bounce off the metal object and are heard through the radio’s speakers. Check out the video for an explanation and demonstration.
