excellent, thanks guys! yeah i managed to get the switch fixed, looks like mine was in better shape than yours debolestis, didnt need to solder teh tracks, just needed bending out.. bit OT, my f16 FLCS has arrived, & i understand that mmjoy supports shift registers... anyone got any idea how they connect up to an arduinio micro pro? also didnt like the rubber boot, so removed it.. but now the joystick seems to have varying spring tension... anone replaced the rubber with something less stiff?

update while i'm waiting for my Arduinio's connected wiring on throttle from right stick to left stick, & all apears to be functioning the way i would expect in regards to the operation of the existing matrix :) so should be straight forward to hook up to mmjoy :) quick question about the pots, i understand i have to wire up a +3.3v what pins do i connect this to on the pots?

The US use Imperial, not metric. http://www.diydoctor.org.uk/projects/screwsize.htm you could maybe re-drill / re-tap the threads to metric if you cant find any imperial replacements?

fantastic! thanks!

photo's would be great! :) i took the switch apart, the copper contact for one side seems to get stuck down...

ok, done a bit more work on this & using gerry's diagram i've documented the matrix from the suncom throttle, current: my plans: this (in theory) i think allows me to keep the existing diodes by joining 4 wires to create one matrix this looks like what gerryk has done also on http://www.gerryk.com/node/46 (11 lines) still waiting for my arduinio to arrive so will join the 2 seperate marix' to create one 4x8 matrix & test & report back! :) also noticed my pinkie switch on the left stick (D7 on my diagram) is actually an on-off with a spring that keeps it in the off position not an on-off-on like the rest... so my diagram is wrong in that respect. my push pull switch seems a bit intermittent (b2+b3 onmy diagram) ... cleaned it up with alcohol wipes but its still not the best... anyone got suggestions for a suitable replacement?

yeah looking at leo-bodars matrix, it looks like the diodes are orientated the correct way on the suncom & its the Spanish guys diagram that's wrong... I suppose i'll try wiring up the matrix's without a full rewire 1st & see if I can get it to work, did you have to replace your Pots? or were the originals ok?

thanks, from looking at this diagram: http://www.gerryk.com/node/46 it looks like I can combine the 4 1x4 matrix in the right stick into 1x 4x4 by simply joining the column wires, is this how you did it? 1 more question, I was looking at this link to figure out how to wire the matrix up & it appears the diodes are the opposite polarity to those on the suncom? http://img853.imageshack.us/img853/8509/3posauto.jpg how did you deal with this? did you need to de-solder the diodes & reverse? or has the guy that drew this diagram got his annodes & cathodes mixed up when he drew it? & how did you wire up your on -off-on switches? do you have them as switch1-off-switch1? or do you have them as switch1-off-switch2? Cheers! Andrew

hi guys, I've recently bought an old suncom throttle with the view to converting it to USB with a Arduino Pro Micro & MMJoy having opened it up I'm completely lost, I understand I will need to create a diode matrix, but from reading some posts here it appears that the throttle has 3 matrix's already: 2 4x1 matrix's & one 8x1 matrix. this is where I get lost, how do I figure out the pinouts? have my multimeter set to mesure resistance but have so far only got one result from the three matrix' how do I figure out where ground is & the row/column layout? or am I better off rewiring it to a single 4x4 matrix that I create from scratch? & connecting that to the arduinio?
