I'm really excited about this - probably much more than is warranted, because as a kid I recall checking these out at the library and eating up all the designs. Lots of good (ie, still relevant) stuff in these old, old books (late 70s, early 80s). http://www.circuitcellar.com/newsletter/0409.html#_Ciarcia%E2%80%99s_Circuit_Cellar, The first three are available now, others will be made available over time. Wish I could just download a PDF of them, though. -Adam -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
