Becky’s latest project over at adafruit shows off some of the possibilities of the cool surplus vending machine coin acceptors they just added to their catalog. It has an Arduino for brains, an LCD shield to report your balance, and an LED that makes piggy squeal glow when you feed him teh monies. The more loot in your hoard, the brighter he glows. And of course it’s done with the usual sparkling clarity and attention to detail that Becky brings to all her videos.

I have to say, looking at those coin acceptor modules has me scheming one of those machines that trains birds to trade coins they find on the ground for food. [Thanks, Becky!]
