DC analog controller hack... could you?
Lilwolf:
So I guess the real question is..
has anyone ever hacked any analog joystick up to a DC controller?
The output of a halls effect is the amount of current... So thats why I thought a halls effect joystick might hack in pretty well. But I'm sure you could simulate this with a analog joystick (5kpot) or a 49 way...

Lilwolf, I've been wanting to work on this for the past 6 months, but other things in my life always seem to take priority. I am actually on a mission to build a fully analog control panel for my PS2/Xbox cabinet. I have a set of 49 Way sticks I'm going to use. I already sent you the circuit for hooking up to a hall effect type input. The Xbox and PS2 have many different joystick manufacturers that all seem to do analog input slightly different. I have yet to see a hall effect Joystick for ps2/xbox...they are mostly now using small potentimeters but how they are wired up also varies (with varing voltages). No matter what, its going to be a custom job for the particular joystick you use.
If you have enough money to buy the $116 happs analog sticks, then go for that. Otherwise try to get a set of used 49-ways (seem to be more available) and use the circuit I gave you. Another upside with the 49-way is that you can actually wire it both ways to pull double duty as digital 8 way and simulated analog with 3 levels of pressure (in 8 directions). This way I would have a toggle switch on the CP which could change the stick to either be input to the analog stick, or the d-stick (on the fly while playing a game).
Now the harder question is hacking arcade buttons to send analog pressure data. This is where a hall effect switch may work best...but I don't feel like buying 16 hall effect sensors and wiring them all up! There must be an easier way!
Sorry for the rambeling...

Dave_K, could you please email me this circuit as well? I am currently putting together a dreamcast powered bartop cab. To emulate the analog controls, I had planned on using a standard 8-way joystick, and a 4pdt switch to toggle between the thumb-pad and analog controls as per the Dc2Jamma project.
Your way sounds much more functional. Also, can the 49-ways be easily wired to function as standard 8-ways?
Thanks

Garvv, a link to the circuit is posted above in this thread by me. Yes the 49-way can be wired as a simple 8-way also (just read one of the LED switches). Some more info on 49-way is found in the Controls section of this site.
