I’m nuts about technological hacks involving mason jars. That’s why I made my long-range internet jartenna – and a cheap and easy mason jar iPhone tripod.
This creation puts both my own attempts at jar hacking completely to shame.
A handmade speaker inside a mason jar so that you can see all the workings. The jar itself serves as the amplification chamber to give the sound its volume.
Unlike many mason jar art pieces, this one you can actually buy, if you’re willing to pay 1950’s prices for a speaker unit.
