I spent a few years developing some real cheap resistance lab probes using the game port.
http://jnoodle.com
Kids would build their own probes and write their own programs in QBasic to read and calibrate the analog channels of the gameport. I had a $3 connector that adapted the game port to use a phone plug.
By next year all my older computers will be replaced with Dells that have no gameports!!!
So, any hints (software & hardware) on how can I cheaply interface a PC to a variable resistor using a USB or SERIAL port?
I'm commited to this project and will have an answer by this summer or sooner but I'd rather not reinvent the wheel
