Most of the time, I read these fori and respond to students who (1) do not read the documentation, (2) want everything handed to them and (3) show a lack of understanding of the limitations and the power of an embedded uC like the PIC18C.

Every once and a while, a student will post an original and workable idea. Sitting back and watching the light bulb turn on is why I do FIRST. In this case the three students who have posted in this thread above me have made that leap.

IMHO, the idea of using a TI calc for data gathering and a simple onboard display is inspired to the point of brilliance.

These things are small and rugged yet powerful. I can think of no better data-logging device to use.

My only regret is that I did not think of it...

I encourage you to follow through with your idea. I may dabble a bit with my TI-83+ over the holidays myself.

Kudos and may the wind be at your back...
