Did the big test today: Will the syringe push peanut butter through the tube? Peanut butter is selected since it is pretty viscous and reasonably easy to clean up.

Short answer: It works!

I'm making a video showing the peanut butter flowing out of the syringe, but I wanted to make this post first. So it's "film at 11" time - you have to wait.

"What took so long?" you ask. "I thought all you needed was a few bolts."

Yeah, well, I also needed to have a stepper motor controller that would run slower than 1 rev/second! So I pulled out a Teensy2 and a Quadstepper and away we go. A bit of work with the AccelStepper library and now I have a controller that will run down to Parade Rest if I want to. Here are a couple of pictures.

Wait for the video!
