I haven't gotten mine yet (should have them tomorrow) and I'm not sure when I'll get a chance to play around with them.
It would be nice to be able to link the pots on two joysticks together, so you'd only have to turn one know/push one button to switch both joysticks between 4 and 8 way.

I think it could be done with 2 resistors (and these may be optional) and one double pole, single throw switch.

The resistors are needed if the pot isn't adjusted to be fully on and fully off.

The only issue I can think of is whether a very small signal from the inductive sensor is sent through the pot. If this is the case, then the joystick may become very susceptible to electrical noise if external wires/resistors/switches are added.

I've ordered a pair, so I'll probably get to experimenting in a week or two, depending on shipping and all my other projects and "honeydews".


Grasshopper:

You could perhaps have two pots, one for 4-way and one for 8-way, and switch between them using a double pole single throw switch. You could then use the pots to tweak the 4 way and 8 way modes independently.

It should be simpler than that.

Leave the original pot, but solder to it. Adjust it to either the way that need the highest resistance. Then wire a pot in series with a switch, then wire these in parallel with the original pot. Switch in the parallel pot, then adjust for the other "way".

No desoldering needed, and at worst, a single switch and pot is needed (per joystick).


Level42:

Mmm, yep interesting and simple solution. But maybe for some reason you might actualy want the full pot range ? Then moving the pot would be the only option.

About picking up noise: twist the wires and that will mostly always solve that problem.

I just got one today from TNT Amusements.
