+ADw-div class+AD0AIg-content+ACIAPg-I've used 100K and 50K pots in my old wheel, using full range. +ACY-nbsp+ADs-Both worked well +ADw-br+AD4- and didn't seem to make any difference in my lap times or car control, although +ADw-br+AD4- the 100k was a little more jittery ( 2) at the high end this was off-set by +ADw-br+AD4- the better resolution. +ACY-nbsp+ADs-IMHO I would think +ACY-nbsp+ADs-250k would be too high (see below). +ADw-br+AD4- Don't remember the exact cal numbers I was getting, maybe 0-250 for the 50k and +ADw-br+AD4- 0-500 for the 100k?, but the counts will depend on the speed of the computer +ADw-br+AD4- anyway (cel 600,-+ACY-gt+ADs-faster gives higher counts). +ADw-br+AD4- +ADw-p+AD4-There used to be a site giving the workings of the standard gamecard and the +ADw-br+AD4- dedicated gamecards at http://www.gplonline.com/tech-talk/hardware-tech.htm but +ADw-br+AD4- the link is dead now. +ADw-br+AD4- +ADw-p+AD4-From memory the jist of the site was that there is a trade off between +ADw-br+AD4- resolution and speed. +ACY-nbsp+ADs-The standard gameport times how long it takes a capacitor +ADw-br+AD4- to charge to give the count seen in the cal menus (one for each axis). +ACY-nbsp+ADs-The +ADw-br+AD4- higher the resistance the less current flowing, requiring more time for the +ADw-br+AD4- capacitor to charge giving a higher count. +ACY-nbsp+ADs-So using a higher resistance range +ADw-br+AD4- will give a bigger range during cal, giving better resolution. So larger ranges +ADw-br+AD4- sound good, but there is problem. +ACY-nbsp+ADs-Higher resistance (counts) requires more time +ADw-br+AD4- for the gameport to read the signal. +ACY-nbsp+ADs-If +ACY-quot+ADs-poll with interrupts+ACY-quot+ADs- is used then the +ADw-br+AD4- program must wait for the gameport to do the count causing drops in frame rates, +ADw-br+AD4- etc. +ACY-nbsp+ADs-If poll with interrupts is not used then the counting can be disrupted by +ADw-br+AD4- other devices giving spikes and excessive jitters (I may have this reversed?). +ADw-br+AD4- The other problem with using high resistance is that the currents in the wiring +ADw-br+AD4- are lower so that background noise now becomes more apparent causing more +ADw-br+AD4- jitters. +ADw-br+AD4- +ADw-p+AD4-So what to do? +ACY-nbsp+ADs-Use the lowest resistance range (count) you can live with based +ADw-br+AD4- on resolution (i.e. do you need to steer in 1/1000 increments with some jitters, +ADw-br+AD4- 1/100 without jitters, or maybe 1/500 with a few jitters) Also use the low end +ADw-br+AD4- of the pots, use shielded cables, and keep the cables as short a possible to +ADw-br+AD4- reduce noise. +ACY-nbsp+ADs-Or get a dedicated gamecard if you still have an isa slot and can +ADw-br+AD4- still find one. +ACY-nbsp+ADs-Don't know if a gameport to usb converter exists or not? +ADw-br+AD4- +ADw-p+AD4-Ken +ADw-br+AD4- PS How do these optical controllers work... can you give a link or part +ACM-? +ADw-br+AD4- +ADw-div class+AD0AIg-gQuote+ACIAPg-
