[dba-Tech] Foot switches / controls

Something like a foot controlled dimmer switch? Wonder if you could build
your own...

I am looking for something inexpensive to use as an analog (as in
continuously variable) accelerator pedal for my son's ride-on toy.  ATM it
is just a simple go/nogo switch.  I am working on a controller to interface
to that switch to allow me to do a "soft start" to ramp up the motors over
time to spare the gearboxes the huge torque they see now as the motors just
come full on.  While I am at it I would like to actually allow a realistic
accelerator which can be varied from off to full on over a range.  Someone
pointed me to hall effect transistors but I haven't found a useful system
there either.

I really have no idea what you're thinking of but here's a link to a foot
pedal that I set a music instructor up with last year, in addition to the
music program, etc.

There's a serial or USB foot pedal:

Does anyone know of an inexpensive foot switch or better an analog
(potentiometer) foot pedal?  I can find them as part of game controllers but
I really want just the pedal part.
