Project: Nickel-O-Matic prints on wooden nickels

Posted on 29. Mar, 2009 by in Projects

This is a neat project that shows some of the really cool stuff you can do with pre-built, easy-to-use modular electronics. The concept is simple: the machine uses an inkjet printer module to print text or graphics on blank wooden "nickels". The whole thing is controlled with a Basic Stamp 2 and a Propeller chip.

Standard radio control hobby servos are used for most of the mechanical movement since they are powerful and easily controlled using the BS2 with built-in commands. A stepper motor is used to rotate the wooden nickel underneath the inkjet module since multiple rotations are required and a relatively high level of precision is needed to assure that the printing is legible.

As you can see, by using pre-made electronics modules like the Basic Stamp 2, you can easily make interesting and fun projects without having to be an electrical engineer or having to spend hours debugging one small flaw when you just want to get something done.

Below are a couple of photos from the Nickel-O-Matic project as well as a video showing it in-use:

Read more about the Nickel-O-Matic and even grab the source code to inspect and learn from! I love projects like this which are so visual and demonstrate that using cool pre-designed modules is almost like building a project from plastic building blocks and anyone can do it with a bit of experimentation.
