This thing uses the tracks, cogs, and associated motor mount frame from the ProtoTank by timmiclark. What this adds to timmiclark’s design is an entirely new enclosed hull and turret with pan/tilt motion. It also features a removable battery cover, held onto the rear of the hull with magnets. Please see timmiclark’s original post for the ProtoTank to obtain those files and information regarding motors and how to print/assemble the tracks.
The turret is designed for the Runcam Owl or equivalent FPV cameras with the same mounting interfaces.
The aft body shell has a small “chimney” to mount the AKK X1 5.8 Ghz Transmitter.
There are standoffs/mounts on the underside of the forward body shell to mount a FrSky XSR or D4R-ii 2.4 Gz Rx.
For power distribution, I just re-used an old power distribution board from a ZMR180 quadcopter that I had laying around.
For power, I am using a Turnigy nano-tech 1300mah 2S 25~50C Lipo Pack. Run times and performance have been excellent with this, and it fits nicely in the hull.
All hardware is M3. Recommend purchasing an assortment of M3 screws with nuts and washers.
The turret uses two servos. 1 for yaw, 1 for pitch. I used: ElectroBot 2X Pcs Sg90 Micro Servo Motor 9G Rc Robot Helicopter Airplane Boat Controls. You will have to trim the tips of the control horns to get the right fit.
Note: Some of the component-level photos shown here are “version 1” components, but I posted them for assembly help where design changes did not impact how parts fit together.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
