Great trick with laser cutter and black paint on the pcb. I wonder how end resolution compares to milled pcb. Also this is one of problems I have with Imgur. How to archive such detailed imgur post? I have tried ripme [1](great for grabbing image sets without addnotations), printscreen browser extensions (mixed results - most do not cope with floating menus and have problems with dynamic image loading), page saving or printing via browser (similar problems with dynamic loading). Does anyone have seen something that could archive imgur post with all content? 1. https://github.com/4pr0n/ripme https://github.com/4pr0n/ripme

unrelated but evernote's webclipper does a good job and can capture the page. You can also 'print to PDF' from your browser.

  I will look up webclipper. Printing as I stated (assumed printing to pdf not paper) does not always work as imgur page is dynamic and does not retain all content loaded on screen (at least on Chromium and Vivaldi).

> Great trick with laser cutter and black paint on the pcb. I wonder how end resolution compares to milled pcb. Eh, I thought this was a point where they made the wrong call. You can get a much better result for less money and less personal time invested - just wait a week or two - by sending your Gerbers off to be manufactured. PCB manufacture is dirt cheap and has extreme quality compared to home-etching your boards.

  In home shop it all comes to what is easiest. Most boards that I do are single runs. If laser cutter can do single run on site without hassle of getting toner transfer or uv run that's great. I did not see that this is different from single run operation (considering how it is wired) so no point to wait for pcbs. That can wait for tens or more pcbs. Also it boils down to personal need. This is hand crafted and tailored piece. With this setup you can easily modify and correct everything to work.

ya I enjoyed that trick too, it was the first time I had tried it but it worked really well.. You can get the traces to be really fine though I haven't measured the actual doable resolution

  Very cool - what settings did you use, and did you have any issues with the copper underneath being reflective? I was thinking of trying this with a K40 for some simple single-layer designs that don't merit waiting a few weeks for fabrication, but I'm a little worried about how shiny and conductive the underlying copper is.

    didnt have any issue with the reflectiveness.. I was using a 75w laser printer. Used the etching settings with 100% power 35% speed. Had to do four passes and then wiped it down with a damp towel
