(...) <snip> There was a guy on the HB list a few months back offering to sell bend sensors for a reasonable price. I figured that if he's into robotics, then he's probably one of the good guys. I took a chance and sent him a few bucks, but I (...) (26 years ago, 27-Oct-98, to lugnet.robotics.handyboard)

Joe, Your question implies that Interactive C does not compile to byte code, so I thought I should take some time to post an explanation of how IC works. Actually, Interactive C does compile, and in fact does compile to byte code, which is then (...) (26 years ago, 27-Oct-98, to lugnet.robotics.handyboard)

This is correct, although the bend sensors aren't all that great. I've got the glove and the accuracy isn't very much, about the best you can expect is what they've got from the glove , ie 4 different bend positions. But if this is enough for your (...)

I'm looking to offload the processing of IR proximity sensors and ultrasound to a PIC(s). I'm hoping to connect the PIC to a HandyBoard via the SPI. I'm trying to decide which is the right PIC for the job. The PIC16C7x (PIC16C76) series supports (...) (26 years ago, 27-Oct-98, to lugnet.robotics.handyboard)

If you go look at the imagesco page the sensor is the Part number FLX-01 and they are priced at $10.00 each. This is where I got my $10 quote ;^( I guess there was a 50% raise in the price since Fred Martin updated the FAQ... Thanks anyway. -- Eric (...)
