[/quote] Nope. Opti-Wiz competes with Opti-Pac and Mini-Pac. GGG doesn't have a competitor for the AKI or A-Pac. |

Thanks for the information. Would've saved me some head scratching. |

The newer analog-only apac v.2 looks like it doesn't need capacitors, either, but it doesn't have buttons, --- End quote --- I saw it mentioned elsewhere as well. What are the caps for in the circuit? --- End quote --- The old way PCs read analog sticks hooked to the gameport was based on how long it took a cap to discharge, one per axis. Each cap was charged through a POT; the lower the POT resistance, the more charged the cap, and the longer it told to discharge. Usually a 5k POT needs a different cap than a 100k POT; and the APac is like this. Not sure how AKI or APac v.2 do it, as they look solid state. And FWIW, there are a lot of other analog interface products out there at the same level as AKI & APac, mostly for the flight sim & race sim crowds. Many can do 5k and 100k POTs. A few to look at BetaInnovations, FlightLink, and Precision to name a few. And a little more back to the original subject, found a pretty good read on encoders vs POTs. |
