Hi Everyone, Just thought I'd share a funny experience from the lab. We needed a 15-bit counter from parts that we have available to us in = the lab, so we took two CD4024 7-bit counters and a dual JK Flip flop to = do the job. =20 Well, we laid them all out on a breadboard, conencted all the power to = the right places, fired it up and saw that the output from the last of = the CD4024's was pretty bad. It was counting correctly and everything = like that, but only after we put some fairly large capacitance across = power. =20 Anyway, after a bit of playing around we realized that this was one of = those breadboards with the split power rails, so we weren't actually = powering the chip up! Needless to say, once we gave it power, the = output seems to be a lot nicer. The strange part is that the thing was still counting properly, power or = not! If only every chip ran like that! -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
