Dwayne's advice is dead on. It works really well. The only problem I've ever had was the wire-wrap wire coming unsoldered at the top, and that was because there was another pad right next to the

hmmmmm.... I have WW wire.... I have to play with that idea. I got WW wire to experiment with radio building. BIG mistake. http://www.learnmorsecode.com/716/716.html Pretty much concluded that

My usual way to fix a board with a missing PTH is to either simply patch from the pin to the next closest node on the bottom of the board **or** scrape the solder mask from the top-side trace, run a

Hi guys Check this out from Marco Reps https://www.youtube.com/watch?v=1hFNj86L7sk&t=42s All his videos have some great info. He has PCB laser etching nailed. He's done this one and some following

Guys, Check the videos out by this guy. (Marco Reps) https://www.youtube.com/watch?v=1hFNj86L7sk&t=42s You can get the kit from

Sorry, it looks like I was wrong about Pulsonix being able to convert from PDF to Gerber. It does work the other way round, but that isn't much use. Leon

The Pulsonix PCB software I use can convert PDF files to Gerbers. I could probably convert that file for you. Leon

You can convert the scanned image to a vector image, the vector can be used to run the engraver. Eg: https://www.dropbox.com/s/x9qc7bqdt3m9l9x/traces-bw.dxf?dl=0 That was done using CorelDraw with

Glass tube? What resonator? With flying mirrors? Ain’t gunna happen. We’re not cutting either, so the beam is going to get reflected back all the time. Still ain’t gunna

Still wouldn't use a CO2.? Back reflections are the issue. Ever see a resonator after the beam goes back into it? That happens at the pierce or etching (which is what you are doing).? Once the cut

This is the sort of thing he’s describing: https://store.zmorph3d.com/ Sticking a laser diode onto a 3D printer works because they’re both lightweight machines that need to move relatively
