What I am talking about is a DIY cheap version of the compu-trainer. I used to program
microcontrollers and it would have been fairly trivial to run a magnetic switch on a microcontroller
interrupt to calculated speed.
But I know comparatively little about interfacing unique HW to a PC under windows.
But this should not pose any significant challenge and with under $10 of HW cost you should be able
to get wheel pulse info into the PC. If the PC can directly read the pulses via an interrupt. If
not then a simple microcontroller with serial interface could do the work and send speed updates
via rs232.
So has anyone heard of any user projects like this?
