DVD* Build Your/Ow Card Fountain

While the price for raw materials may be low, the process is fairly involved. The authors don't provide an estimate of the time, but I would say that this is at least a day project. That is, if everything goes right.
By the way, this is a basic card fountain with no fancy radio controls. You simply press a button on the device and the cards go flying.

There's some shopping involved, but most of the parts should be found in hardware and radio parts stores. The authors purchased many of the electrical parts at their local Radio Shack. However, I've found lately that my local Radio Shack is no longer carrying the traditional electronic parts that they’ve offered in the past. But I'm sure these parts can be easily purchased via the internet.
