The previous blog post detailed the pcb design (and postings before that, the schematic and pinout.) Elecrow was having a sale at the time and was one of the recommended places to try out (along with Seeed and others.) Elecrow had ready to use Design Rules and CAM processing files for Eagle as well.. so being relatively painless to use, and cheap as heck.. had to try them on! (The Design Rules provide a handy reference for the pcb house with the limits of their equipment, so you don't have traces too close to the edge, or unavailable drill hole sizes, or other minutia. The CAM file is a set of macros to help produce the type and style of files they will need to produce the pcb. “Gerber” may be the general standard, but theres a lot of wiggle room in that general arena.)
So without further ado, see the picture; its a very simple pcb design, and is smaller than a credit card (since it is supposed to ultimately slip into the cartridge case for a typical Atari 2600 game cart. Its unlikely I'll be able to afford any actual cart cases, so fitting into somethign common seems the way to go.. but even the crappy flooded out sports games for the 2600 have become pricey of late; if anyone happens across a small cache of dead carts, let me know :)
I wasn't entirely sure what to expect .. rather assumed I completely blew it, or the 'ground pour' would cover the whole thing .. due to complciations with the cam files, or noob mistakes in EAgleCAD or any number of things. Gladly, none of these came to pass.. it turned out very nearly perfect (at least, turned out as I'd designed, and then some.)
Of interest ..
I'll definately try Elecrow again, though Seed gives you the different pcb colour choices ….
