Secret Project Revealed

For the past 6 weeks I’ve been secretly toiling away at creating a CNC machine. The project was largely on the back burner, until recently. I’ve been collecting scavenged parts since last summer. After my last visit to a job fair I had realized that the job market was in terrible shape. I knew I would probably be looking for work for a long time. So I decided to put that extra time in-between interviews to good use. This project is by no means complete. In fact, I’m just getting started. 🙂

Stepper Motor Stockpile

Stepper Motors

So, I’ve been busy stockpiling a massive collection of stepper motors. These have mostly been dug out of old dot matrix printers and laboratory equipment (dumpster diving, LOL). I’ve been able to test the small and medium motors with just a ULN2003A chip but the bigger ones need heavier duty circuitry. My collection is nearly complete. What will I do with these motors? ….. some kind of 3d printer :).
