Contest: Make a mechanical vending machine

Contest: Make a mechanical vending machine
The good folks at the The Kugelbahn Blog have announced a competition! The goal is to design and build a coin-operated vending machine that dispenses small German chocolate bars. The deadline for the competition is January 31st, 2010.

Machine Specifications
The apparatus is to be purely mechanical and hand operated. With the input of a 20ct-coin the machine should output one little chocolate bar. The ALDI Moser-Roth chocolate package (found in Germany) contains 50 pieces measuring 5mm x 35mm x 35mm each, which are cheap and stack well (see the picture above). The coin-acceptor unit is to make possible the chocolate output with one 20ct-coin. Other coins with a smaller diameter should fall into the return area.
