Reverse Engineering a 27MHz Radio Controller Transmitter (RC Transmitter Part 1)

This is a detailed walk through of reverse engineering the signals generated by a 27 MHz radio controller unit for a radio control truck. An oscilloscope is used. 00:20 How we know it is a 27MHz controller and not one in the GigaHertz range. 00:50 Connecting the transmitter to the oscilloscope 01:25 Mains Hum 50Hz 01:45 Turn the unit on and starting to investigate 02:00 Carrier wave 02:20 Trying forward 02:43 Using high pass filter (capacitor and resistor) to eliminate 50Hz Mains hum interference 03:42 Continued investigation 05:01 Signal for forward 05:36 Signal for reverse 05:47 Investigation of turning signals 06:49 Duty cycle for driving straight 07:24 Duty cycle for turn left 08:10 Duty cycle for right 08:16 Summary 08:55 The music in the machine analogy 10:04 Building blocks for a transmitter
