Three Penny Radio

If you love WHYY as much as I do and you’re down for a little DIY action, scrape three pennies from your sofa and try building this tiny radio. Full instructions are available and the electronics involved can be had at your local Radio Shack. There’s even instructions on how to make your own batteries out of vinegar and aluminum foil. Insane! You’ve got to check it out if you’ve got a soldering iron and a free weekend.
