Taranis Buddy Box - TGY-IA6B

thingiverse

My daughter wants to learn how to fly my quadcopters, so I had to come up with a safe way for her to get started flying these flying machines. A wired buddy box system is a well-known and proven solution for teaching someone how to fly, but come on, it's 2017 - who needs wires anymore?! I searched the internet and found that the FrSky Taranis module has a few pins that could make it possible for me to DIY my own wireless remote buddy box system. Starting with OpenTX 2.1, the Taranis offers the option of using the PPM pin in the module bay for Trainer SBUS or CPPM input. I created my own little PCB containing a Turnigy TGY-IA6B receiver (which came with the TGY-I6s TX that I bought for my daughter) and connected it to the PPM pin of the Taranis module bay, configuring it to use SBUS - I prefer this over CPPM. Since this receiver takes anything between 4 and 6.5 volts DC as a power source, the Taranis module bay Power Pin isn't suitable because it provides battery power, which in my case is 12.6 volts (3s Lipo power). So, I added a small buck converter to my PCB to bring down the 12.6v battery power to a more comfortable 6 volts instead. A bare PCB stuck in the back of my Taranis doesn't look very nice, so I wanted a nice little case to go along with it. Owning a 3D printer once again proved its use, so I decided to design and print a nicely fitting case with a bracket that holds the antenna's at a somewhat correct angle. Enjoy or remix if you want! Cheers. P.S. Most of the other Taranis module mods have those locking tabs on the side - I didn't include them in this model because they break easily anyway.
