There’s nothing better than looking at the unreasonably high price of an electronic gadget, and discovering its cheaper and more powerful home-brewed alternative.  David, at Volunteer Lab Rat, has posted a number of interesting projects, including a tesla coil, FM transmitter, and wireless device range-booster among other things.

It’s so easy to forget that so many of these projects consist of components no more complicated than transistors, capacitors, and resistors combined in the right way.
