Voltage-to-resistance converter for using any joysticks

Yes. I've seen at least one team with a PC on board. (Bought in several sub-$200 parts, then assembled by the team.)

Edit: I thought that was referring to the robot (e.g. through the program port). A PDA may not send information to the OI.

Further to my previous post, the present 100 KΩ limit on joystick ports isn't a rule, it's a just hardware specification for the joystick port (to get the right voltage levels). Previously, control system components (e.g. the OI, joysticks and accessories) were covered by the additional hardware list. Taking 2000 as an example, the KOP included a 100 KΩ potentiometer, Small Parts doesn't sell potentiometers, and there was no entry for a potentiometer in the AHL. Therefore teams were effectively limited to 100 KΩ potentiometers.
