Who loves a good R2-D2 robot? Everyone, but especially young Star Wars fans who — frustratingly — have no problem spotting a controller and spoiling the illusion of an R2 unit brought to life. [Bithead942]’s concealed his R2-D2’s remote and re-establishes the illusion of an autonomous droid — no Jedi mind-tricks necessary.
[Bithead942] prefers to accompany his droid in traditional a Rebel Alliance pilot’s suit, so that gives him a bit of extra space under the jumpsuit to help conceal the controller. Dismantling a Frsky Taranis X9D controller, [Bithead942] meditated on how to use it while so concealed. In a stroke of insight, he thought of his unused Wiimote nunchucks, and launched into the build.
Since he only wanted to use the joystick and buttons, he had to perform a bit of circuit sidestepping and run some extra wires to get all the functionality he wanted from the nunchuck. That achieved, an appropriately sized project box needed to be cut to size with a lightsab– a band-saw and glued together, punching some holes for the various buttons, wires, cords, barrel plug for recharging, and the antenna in the process. Like a Jedi — or Sith! — using the force to guide them in building their lightsaber, [Bithead942]’s remote worked almost perfectly on the first try.
With the project box riveted to a padded shoulder harness, it is barely noticeable under [Bithead942]’s costume, and wrist straps manage the cables along the length of his arms while also letting him drop the nunchucks to hang if needed. Shortly after finishing he took his R2-unit for a test-run using this new setup at a convention — with great success! He did run into a few issues: notably, the harness moved around a bit too much for comfort and the rocker switch that controlled the head rotation fell apart a few times, so they’re getting swapped out. The concealability of the nunchucks are a vast improvement over the bluntly conspicuous controller, but aren’t perfect. Still, there were no heat issues and other attendees were generally amazed at the seemingly independent droid.
