DIY sequential shifter for PC simulators

Sorry, not SAAB-related, but Im an avid iRacing fan and with the help from my dad, I built a homemade sequential shifter for PC simulators. The shifter is made from parts that you can buy in a hardware store, except for the shifter-knob which was bought from Ebay. I used a 32-button USB interface from Leo Bodnar Electronics for button activation. The shifter feels really heavy duty and works great! Hope you enjoy this video, cheers!
