So several tests of the original plan of using a friction-wheel to spin the dome suggested that while it would “work”, it was neither reliable nor consistent. Matthias Wandel to the rescue! Using Matthias’s gear template generator I spec’d out a ring … Continue reading
Been too long. 🙂 The trip to Marathon was less than I’d hoped. Well, let me correct that…the TRIP was fantastic. Had a great time, loved being down there, and thoroughly enjoyed the time with friends and my son. The … Continue reading

Shorting your 12V DC power supply across your Arduino and motor controller is bad.
IT WORKS! 🙂 In my spare time this week, with the kids’ help, I was able to build the motor-drive system for the shutter door. It’s a simple system, using a windshield washer motor and a wood gear and rack … Continue reading
