2018 update: Items needed: - 16 mm aluminum tube (you have to drill it an 8 mm hole) - V3 Microswitch SPDT 16a Micro Switch (http://www.ebay.es/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 (i bought one from a chinese store, cut it and left 3 rings of it). - 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'll have to solder the P0 pin and GND to your Switch. -Dremel alike tool. -Driller (to make an 8 mm hole to our tube). -Micro usb cable. Software needed: -Arduino IDE (https://www.arduino.cc/en/main/software). You'll have to install the trinket keyboard library's and the Attiny85 board drivers (because Arduino IDE have to recognise 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). Handbrake code download: https://drive.google.com/file/d/1ueVhz8GHW2HozKdMkt_V-fGilqvFoX9U/view?usp=sharing The attiny85 hardcase is optional. Also you can change the way you map your handbrake switch. In 2015 i used and old Usb Joystick, but this time i used an Arduino board clone). Once you have completed your DIY handbrake you'll have to screw it to your shifter.
