The OpenSAM by OHM is developed for filmmaking amateurs and professionals. The design allows a broad spectrum of cameras of varying sizes and weights to be stabilized. The use of 3D printing technology for the mechanical construction means that it can easily be reproduced and any design changes are easily implemented. The 3D printed parts are also lightweight (actually lighter than any commercial carbon-based designs). All parts were printed in PLA using Ultimaker Original 3D Printers or Bq Witbox 3D Printers and the files have been made available under an open source license through our GitHub and website.
The brushless gimbal stabilization system uses three brushless motors to stabilize the axes. One 8-bit brushless gimbal controller (BGC), an expansion card and an IMU (Inertial Measurement Unit) is all the electronics needed for assembly. Our model seen in the video and pictures cost under $200 in parts, excluding the 3D-printed parts (which are free to print as students in Denmark). This should be compared to the price of similar gimbals, which start at around $1000.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
