RE: [atlas_craftsman]an experimental measuring system
I came to the same conclusion about using an Arduino as just a DRO. Beyond the fact that it costs more than an iGauge, it is nothing new. IMHO, the fun is just beginning when you can pull the caliper data into a processor. Why stop at that point?
I write in C, but the arduino method is fairly efficient as it's a fairly thin layer on top of C. And it gets people programming without the host of fussy details you need to know to write C for a small processor without an OS. It isn't that spendy making your own boards these days either. I can get three boards for $5/sq.in. and I use PCB on linux so that's free. But i've seen freeduino blanks for $3 which is hard to beat. I like the serial versions which aren't in favor anymore, because USB isn't good for any distance. But yes, even though I can design and make my own boards it's a lot easier to ride the arduino shirttails.
I did design and build a DRO shield, but abandoned it because it would cost more than the iGauging stuff.
