Head Tracking w FlySky GT3B and Telemetry Dashboard for Gmade GOM 1/10 Rock Crawler

Image
The project is divided into 3 parts: Add head tracking (Channel 4-6) using Teensy 3.2 and toggle switching (Channel 7 & 8) functions  in Flysky GT3B pistol transmitter  Add front and back FPV camera into GOM Add telemetry dashboard function using ST7735 and Arduino Nano PART 1: Add head tracking function(Channel 4-6) using Teensy 3.2 and toggle switching (Channel 7 & 8) in Flysky GT3B pistol transmitter. (Thank you for sharing by Dylan Fairbanks for instruction of adding head tracking function and additional channels using Teensy 3.2 and Flysky GT3B) Pre-requisites:  Basic programming skill Basic soldering skill Understanding of PPM and PWM  Components FlySky GT3B Transmitter and FS-R9B 8ch Receiver Teensy 3.2   SkyZone 03O FPV Goggles (with Head Tracking Function) JR (Head Tracking) Cable(come with 03O FPV Goggles) 3.5mm Stereo Socket 2-ways Toggle Switch (3 Pins) 3-ways Toggle Switch (3 Pins) Axis Pan&Tilt Camera Mount 2 x Micro Servo  Co...

Convert an old servo to a light switch

Image
Use a MG90s servo  Unscrew and remove the cover Cut the wire connected to motor Wire to Led light(please check the voltage of led light) Plug into a channel in RC Receiver and test If led light keeps on but turns to dimmer/brighter while switching, use screw driver to adjust until led turns to on/off If led light keeps off while switching, rewiring cable to +/- of led light
