I converted a Nerf Rival Nemesis to be head tracked, radio controlled, and still operated FPV using DJI Googles V2 and DJI vista vtx.
The blaster is mounted in a pan and til mechanism that I designed in Tinkercad.
I am using two different Arduinos in this project.
One for the head tracker an Arduino Nano 33 BLE. I forgot to mention it in the video but I power it from the DJI goggles V2.
I am also using a regular Arduino Nano in the blaster, which converts the PWM signals from the RX into regular "high pins" the relays understand
