Some fun packaging
The Three Penny Radio is small enough to be fit into some fun and interesting containers. We found a nice wooden box at a local store, and built a radio to fit inside it.
Instead of pennies, we used upholtery tacks, stuck into a bit of cork for a base. The cork was cut to fit the box.
The tuning knob is a plastic soda straw glued to the brass shaft of the variable capacitor, and exitting out of a hole drilled in the back of the box. We used a small "N" cell battery which fits nicely in the box, and powers the radio for weeks (there is no off switch). You can remove the battery when not using the radio to make it last longer. The earphone coils up inside the box for storage
At another local store we found a little soap dish that was just begging to be turned into a radio.
We cut s slot in the lid to let the earphone wire come out while the lid was on, so the radio fits in a shirt pocket nicely with the lid on. Like before, the earphone coils up inside the box for storage
