I am not responsible for creating this mod, I found it through searching the web, and I have customised it to my needs and style.
This is where I found the mod originally...
Please note, this is a modification of FM transmission equipment, increasing the range of a range-limited device may not be legal in your location, so do this entirely at your own risk, if men in dark suits come knocking, it is not my fault!!!
(Thanks to vandmatt who reminded me that C means capacitor and R means resistor when it comes to labelling on the circuit board... :) )
Step 1: The TuneCast3
The display is a neat OLED display, it's nice and clear in both the dark and bright sunshine, but all you need to do is set your frequency and that's that... :)
Anyway, on with the show...
