He did what in his cup?

I have been working on several things since my last post. First, I made a vertical shooter game on that LED matrix. I don’t have a good video of the finished product yet, but for now below is a video demonstrating the custom controller.

I also stumbled onto some really nice craft steel material at my local fleet farm store. These metals are from K&S Precision Metals (http://www.ksmetals.com/) and they are fantastic. I got a stainless steel rod and a stainless tube that would fit around it, and the fit is about as perfect as a non-machinist can get for making homemade pistons. Then I bought a cold-rolled 1/8″ rod to use for a piston rod.

Why make pistons? To make a model steam engine, naturally. I managed to craft a rough cylinder, piston, and rod (complete with mounting hole in the end) using just my Dremel (for cutting and grinding) and my drill press. The mounting hole I accomplished by grinding halfway through the 1/8″ rod on one side to make it flat, then drilling a 1.5mm hole. Below are some pictures, followed by the promised LED video.
