Motorcycle Rally Roadbook Controller

Description

I needed something to controll my DMD2 tablet on my bike but the regular rally controllers out there cost a fortune.

This would fit a 22mm handlebar and its about 22.5mm wide!

you will need:

Assembly:

put the m4 nuts into the backplate. they are pressfit. if they are to loose, secure them with some glue.
Add the buttons and use the included nuts to secure them. start with the top one, then add the 2 way rocker. Follow with the rest. make sure the terminals face the outer walls so sodlering is easier.
use locktight or superglue to secure the nuts
get a piece of wire, strip it and solder up ground to one of each button terminal. basicly providing a GND backbone. this way you wont have to solder that much
pull through the cable and solder up the rest.
secure the end of the cable with a ziptie inside the case (just around the 6 core cable ). so it cant be easily pulled through.
put on backplate
use the M3x6 screws and secure the backplate
get a waterproof case and put your microntroller in there, i used an outdoor junction box and sotred that somewhere inside my bike,

Software:

you'll find the barebone sourcecode here https://github.com/achmed20/rally-controller
if you have a regular esp32 dev board, solder the wires according to the pin layout (all pins must support interal pullups)
or
change use or own layout and change the pins accordingly
compile and flash the firmware (platformIO works best for me)
Pair the controller to your device, if it doesnt work, you may need to reboot the controller after flashing
it will appear as “Rally Controller” and will simulate a gamepad.
the top button will support multi press and offer more button mapping.
- 1x = x
- 2x = y
- 3x = lb
- long press = rb

Note:

mounting the Buttons is a bit of a pain. You cant turn the Nut so you have to turn the button itself. once its fastened, you probably should glue it own so it doesnt rattle loose
