Those look really cool! If one scanned or photocopied the board before using it, the copies could then be used for parts-layout noodling.
ReplyDeleteThis style of prototyping pad needs a name, though. Something catchy ... there's already ME pads and Muppet pads. Hey, maybe Flowers pads? Hold on, how about Lily pads? I mean, a lily is a flower, right?
OMG... Lily Pads. That's hysterical. Maybe if I come out with a Rev 3 I'll give it that name, or call this the original "Lily Pad" style when I come out with another kind. If I ever create another, that is! 73!
DeleteBetter yet, as Ryan kindly made the gerbers available you could do your parts layout noodling on the PC.

Exactly! That's why I made them available. People should be able to do what they want with it :)
DeleteGood idea! Can you move the components around without having to redraw them?
DeleteBack in the bad-old days of PCB layout-by-hand (at 6:1 scale), we used what we called "puppets"--little clear-vinyl decals (only-slightly sticky) of component footprints that could be tweezered around on the mylar at will with no drawing, erasing, redrawing. Once we got the parts placed the way we wanted them, we'd put down permanent footprints on another layer of mylar (all kept together with registration pins and targets) and then lay down black "Chartpak" tape for the traces--all done on a big light-table. No auto-routing or automatic design-rules check for us, and Gerber was what you fed your babies! BTW, I don't miss those days at all. --Todd K7TFC
Exalent idea I'm sure meny if use will be using this .
