Lots of things are programmable these days. If you hop into most modern cars you will see switches for things like ride comfort, traction control, performance style etc. When you hop on a bike you would expect the ride to stay consistent. John Brack, David Dang and Broc SommerMeyer from Colorado State have built this Arduino based Bike Shock Project which Allows the Shock to be Programmable. It uses metallic particles suspended in oil which is acted upon by a magnetic coil which allows the fluid to thicken when magnetized. Feedback is provided to the system using a potentiometer that allows the system to apply the correct amount of electro magnetic energy to provide the desired ride.Â
