My third instructable:
How to create a programmable rising and spinning Halloween Skull using fischertechnik elements!

My vision was to create a scene with a skull rising out of a coffin, spin in the air and return to the coffin. The device raising and spinning the skull would be hidden beneath white tissue paper. This is an instructable that focuses just on the controlling mechanism.

I play with different educational manipulatives for a living. (Visit www.weirdrichard.com). Over the years I have built different holiday themed models using all sorts of toys. It is very easy to create awesome Halloween models with fischertechnik elements. This instructable will describe how to create a spooky Halloween Skull using fischertechnik and a programmable brick.

Note: The CAD looking images were generated by LDraw/MLCAD and a fischertechnik elements library.

Step 1: Gather the Parts

You will need to gather your elements. I purchased an inexpensive plastic skull from Target. Hobby knives are widely available. There are a variety of programmable bricks including fischertechnik, K'NEX, INEX, Super Cricket and the BASIC stamp. I used the PCS Programmable brick. The fischertechnik elements can be found in a range of kits available from a fischertechnik retailer, and the specific elements can be purchased individually from www.fischertechnik.com.

The List:

A cheap plastic skull
Hobby knife
Programmable Brick with batteries
