I'm going on vacation for three weeks, and then I intend to see if I can get the projects electrics and mechanics done at least before school starts again. I've been getting my CNC Sherline mill working properly for that, the mechanical parts are a fairly complex (for me) set of interlocking bars to hold all the parts, lots of work to be done there just to get everything assembled. Be much easier to figure out the math if I've got a little cube in my hand. I'll be able to test the much more simple cases of moving along one axis and hopefully start to work up from there, hopefully! -- pete@petertodd.ca http://www.petertodd.ca -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
