I've started the second "first" board in the Getting Started manual. So far, it only goes through creating the schematic and symbols (no details on those), a footprint, and the hooks you need to tie them all together. No board work yet. This board will cover the gschem integration, custom footprints, and autorouter. The third will add SMT, polygons, vias, and multi-layer boards.

The first is an LED "workbench" which lets you drive two types of LEDs, and make measurements on one (the RGB one). The second module is an array of 128 red and green LEDs to make an 8x8 "screen". http://www.delorie.com/electronics/usb-gpio/ Yes, I hand-soldered 128 LEDs and 80 through-vias. Hence the insanity, although the LEDs and transistors were reflowed on my hotplate. I still had to put down 256 paste dots and place all the LEDs. This board really pushed the accuracy of my PCB fab setup. The traces were all 6.7 mil, and the vias were 13.5 mil drills - and only one fab fixup was needed (the other wire was because I delaminated a trace while repairing one of the LEDs). Keep in mind - the board is only about an inch square. Those are 0603 LEDs and SOT-323 transistors. _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
