Hi i just going to show my project that is finally finished after lot of work on them and changes in the project (sorry for crappy pictures, mobile camera): The brake and clutch are pressure operated, the brake uses the famous meas spec sensor and a sam sensor 500psi on clutch, on the slave part i got rubber bushings for brake from a garage repair shop near my house and 2 springs for clutch, does anyone know if there exist diaphragm spring, somekind of little version of them?? i would like to play with those to see effects as they are used in real clutches, for throtle a cheap 100k linear(response) pot would like to get some linear pot on phisical movement but here where im from (Canary Islands, Spain) i think will be difficult. The footrest is an omp one it seems to be and outdated model cant find any photo painted black original was somekind of red/pinkish colour i hated . This are the master cylinders for brake http://www.ebay.co.uk/itm/220806988212?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 i got to buy these cause i broke the original ones (clutch one) sealings cause of using mineral hydraulic oil then i went the safe road with dot brake fluid, the masters got a little deadzone on initial travel i didnt like (the circuit was bled correctly) and what i did was to put a little washer where the pedal is in rest position to avoid this deadzone and now got much less than before. Slaves hoses and fittings are from this page http://www.speedwaymotors.com/Speedway-Pull-Type-Slave-Cylinder,7169.html (here slave page the rest pieces i mentiones earlier from there too). The pedalbox i bought from ebay back in the day a kit with master cylinder balance bar and the adjuster for brake balance now cant find them seems the seller has changed account or something and cant find them http://www.ebay.es/itm/universal-fl...hicles_CarParts_SM&hash=item2580d14ac7&_uhb=1. All the electronics goes to a derek speare board inside the black box on the last photo, the 3 pin conector is for handbrake and is wired to the board and the 15 pin connector (3 pin not soldered) is for a future button box + steptronic sequential upgrade and here is where im going to need a little of help . I know how to make the 6x6 button matrix but im lost on the diodes side, dont know if they are completely mandatory what to choose where to buy and how to connect them etc... another question is if in the derek board with brake amplifier i can connect rotarys switches / encoders or just buttons. The handbrake now is from here, same man i bought pedalbox, there are two versions 300 mm or 600 mine is big one. http://www.ebay.es/itm/151205614749 same slaves as the pedals and the master is the same as clutch, used same trick from pedals to avoid deadzone.
