Arduino MocoSlider TimeLapse Unit

Just finished my new Motion Control Unit for the circular and linear tracking dolly. I’ve did the holes, buttons and engraving with my little cnc machine. The electronics fit perfectly in the case and everything is tidied up. A big thanks goes to Duncan Frazier for the arduino code. It contains a TimeLapse & Slider mode. The 9 pin SUB-D jack connects to the stepper motor of my dolly and the mini jack goes through an adapter cable to the Canon camera. Now I have to adjust the code for my stepper motor to work properly.

Skater Dolly + Arduino QUICKTEST

Here is a quick test with the Skater Dolly in action.

Arduino + EasyDriver + Stepper Motor

The speed ramping is not included yet and therefore the skater is stopping abruptly and shakes a little bit. But the other functions are working great.

Motor unit for skater dolly

Finally the house moving is complete and I had some time to continue the work on my “Motion Controlled Dolly”. I’ve designed a quick plate that sticks directly on top of the metal screws of the skater dolly. One little (but very strong) neodymium magnet holds the whole plate with stepper motor to the metal screw. On the motor side there is no magnet because this would affect the motor itself. I’ve also intentionally left out the grey plastic wheel on the stepper motor for you to see how the unit looks like when it’s assembled. The whole motor unit can be fixed and removed in 2 seconds from the dolly.

Now it’s time to power up this thing and do some tests.
Unfortunately Brian didn’t had time to finish the code yet, therefore the acceleration and deceleration ramp is not included. Hopefully he will have more time this year.
