Here is the list of items needed: - 16 mm aluminum tube (you will need to drill a hole in it that is 8 mm in diameter) - V3 Microswitch SPDT 16a Micro Switch (http://www.ebay.com/itm/V3-Microswitch-SPDT-16A-Micro-Switch/251827572523?hash=item3aa217cf2b:m:mONdUDFbmsgXjdcCSmAGbFg) - Two bolts (3x30 mm) with 2 nuts - One bolt (8x50 mm) with 1 nut - One spring (you can purchase one from a Chinese store and cut it to get three rings) - One Digispark USB ATTINY85 board (to emulate a key for our handbrake) - I bought this one: http://digistump.com/products/1 (from Aliexpress) - Two wires Tools needed: -Soldering Iron: You will have to solder the P0 pin and GND to your Switch. -Dremel-like tool. -Driller (to make an 8 mm hole in our tube). -Micro USB cable. Software needed: -Arduino IDE (https://www.arduino.cc/en/main/software) You will have to install the Trinket Keyboard library and the Attiny85 board drivers because Arduino IDE needs to recognize the board. -Digistump Digispark drivers (https://digistump.com/wiki/digispark/tutorials/connecting) -Handbrake Board Code (this code enables the board to push the COMMA keyboard button mapped to our switch).

You can also change the way you map your handbrake switch. In 2015, I used an old USB Joystick, but this time I used an Arduino board clone. Once you have completed your DIY Handbrake, you will need to screw it to your shifter.
