I ran across this video. In it the build puts together a PCB using small pieces of PCB superglued to a larger piece. Not a new method, but beginners may find it useful. Years ago I purchased some Rogers Duroid pcb, it is 1/32" and teflon. I use a paper punch or a leather hole punch to make small discs of pcb. The Teflon material makes it very easy to punch. It is much easier than making s...

I've completed my first PCB design in Eagle. Thinking of sending it off to one of those small-batch fabs. But, I'm wondering if anyone would be willing to take a look at my design and giving me any pointers or gotchas? I'm looking for both aesthetic and technical input. On a related note, what's the best way to share my design/PCB on this group? Thanks, Daniel.

Just curious here. I managed to break the tiny coaxial connector on my express card TV tuner. Decided to remove the connector from the PCB, cut the small coaxial plug off the supplied lead and solder it directly to PCB. Having got the connector off the PCB I checked for shorts with a multimeter and got 1.1 ohms. Couldn't see any solder shorts so thought maybe I'd overheated a component...
