I was recently visited by musician and instrument maker Evgeny Nemov - also known as "Captain Nemoff". Evgeny told me about his project to get people to make and play home made cigar box instruments. Lots of interest for this in Moskow, he said.
Evgeny gave a short demonstration in front of Ringve museum using one of his electric cigar box guitars and an amplifier made from an old transistor radio. Big Missisippi blues sound from a very small instrument.
You can download plans for making your own cigar box instrument, or buy a finished one from Evgeny at Cigar box nation.
