Zeeland bridge time lapse - First NanoMoco field test

Door andre op

This is the first test I did with my dolly that is converted to the NanoMoco electronics. The sequence was taken at one of the most popular dive sites here in the Netherlands. My "old" electronics consisted of an Arduino, a custom made shield to control the camera and a stepper motor controller. I am currently beta testing the new OpenMoco NanoMoco board. This is a small 1.5 " x 1/5 " electronics board that holds everything you need. The boards holds an AVR micro controller, a stepper motor controller, electronics to control your camera and an RS-485 chip. The RS-485 connection can be used to daisy chain as many boards as you need. The NanoMoco electronics provide a complete platform that you can use to create advanced multi stepper motor solutions.

The software for the board is still under development, but it is stable and functional enough for my 2 meter long dolly. The dolly performed very well during the test. I had some issues with torque last week, but that was a matter of setting the correct parameters. The new firmware can also support continuous mode like the DP dolly. I hope to test that later this month.

I truly believe that this board and it's software provide a stable basis for many, if not all, DIY motion control projects. The board will be cheaper than the combined price of an Arduino and a stepper controller. The size is awesome because the board fits at the back of a NEMA 17 stepper motor.

 

Below you can see some pictures of my modified dolly holding the NanoMoco electronics. This really is a major change since I posted my first blog about my OpenMoco bested time lapse dolly.
