We have covered many handy camera accessories and filmmaking tools here in the past. The SnapMoco happens to be an affordable 3-axis motion control system for your camera with an open control protocol. It consists of the SnapMoco Rotary Unit and the linear motion SnapMoco Slider. The rotary unit allows the camera to pan or tilt, so you can use it for timelapses. The slider supports linear motion.
What’s neat is you can combine multiple sliders or rotary units to accommodate your project. These products are driven by step motors and have drivers with an open protocol. You can daisy chain up to 32 devices. The SnapMoco system is Arrduino, PC, and Raspberry Pi friendly. You can find the product on Kickstarter.
