Cheap analog joystick idea

I got a bunch from Allegro. They had a minimum limit, so I have too many. I need to check at home to see exactly what I have, but PM me if you want a few or four.
Note - if you buy them on your own, be sure to get the "linear" or "analog" Hall Effect sensors; most of the current ones out there are hall effect switches (ie: digital).
BTW, Allegro has some okay schematics on-line, too, explaining the diiferent ways to set up hall effect sensors relative to the magnetics. AFAICT, DC pads use the standard "head on sensing, single magnetic", except in dual (on both sides of the stick). Atari's Hall Effects used the "Slide-By Sensing", with the magnetic polls perpendicular to most other ways (the first of the two "slide bys" shown in Allegro's docs).

PM sent.

what if you found a way to physically attach the end of the joystick ontp the knob on the dreamcast controller? (or any analog controller for that matter)

Trimoor:
It might work with a DC controller, but I'm going to try for a less messy hack.
Most analog joysticks have pots connected at the fulcrum. This is not easy to add to an arcade stick. If you know otherwise, let us know too.
I'll try to get this working as soon as [u_rebelscum] gets back to me.

Ok, this dosnt make much sense.
You say you want an 'arcade quality' analog stick....
Yet, you want to use a typical 8way joystick as the mechanism?
I do not think you realize all the factors here.
A heavy duty arcade analog stick uses a huge rubber gromet to produce the resistence - and center the shaft. It also has a trigger and additional buttons on top. Most Built of heavy duty steel.
An 8way has limited durability. Its spring is barly able to return its light shaft. The shaft has no triggers or additional buttons. Excluding the shaft... the entire base is light duty plastic)
The cost of a used real arcade joystick on ebay is arround 30 to 60$
Add up your cost of:
1) DC joystick
2) DC to PC adapter
3) Happ joystick
add other hardware, tools, time...ect...
and you will end up
paying about as much for a hacky clunky mess.
Esp bad will be if the sensors arnt alligned perfectly.
This could cause weird positional output.
