How to make Clear Glass PCBs

This is a video on how I make my clear glass PCBs. I'll be making a blog post sooner or later with more detail.

***ADDED*** Here's the source file + (PCB/SCH (For ExpressPCB)) and the PDFs of them.

Copper: You can buy this -- but I'm worried since there aren't may left, so you can just ask and I'll send you a sheets for $5/ea + shipping. http://www.ebay.com/itm/copper-foil-20-each-sheets-1-oz-sf-11x18x0-0013-thick...

Do you think it would be possible to make an X/Y pad with this process using resistant strips or ribbon controllers. I think it would a sweet way to control the 5V CV inputs of an analogue synth.

@BelfonteFurnace I have never tried layering this stuff, but I would not imagine it working too well. I don't really know how people do X/Y touch sensors.

[BelfonteFurnace]

@CNLohr Ahh well, guess i can only find out through experimentation. I'll give it a go anyhow, if it doesn't I'll just make some nice clear PCBs. these things look gorgeous! thanks for the tutorial

[CNLohr]

@BelfonteFurnace You could always try with the not-glass variety. Additionally, I only have about a 50% yield when making boards of about 20 square inches and up.

Would some simple cyanoacrylate glue( superglue ) work? UV glue isn't available here :(

[CNLohr]

@mrpsypi super glue will not work, I tried several times with it. If it did, there would be many other materials I could use. Maybe epoxies would work, but right now, I'm going to be trying another UV glue. If it works out, it'd be cheaper and easier to get (Since it's Loctite brand). I'll give you a heads up.

This is a flawless process and you did it with one hand, while filming and while talking.

You are my hero.

:)

Great video!

@lilhojo123 I try not to get oils on the side I join the copper to.
