Really interesting, and dead sexy.

Video is super long, so skip to the end if you just wanna see the final product.

That was really cool. I recommend people watch the whole thing.

You thinking about doing some of these there D? Before he finished, I was thinking, "how the hell would I drill these?" but then it made sense. I think it would be fun for a limited run or something...or a touch-based controller like the video.

[McSpunckle]

I'd love to use it for some SMD stuff if I could find a less touchy way to do it.

The comments of that video suggested that pyrex glass would be more resistant to the etching solution. I bet it would be less likely to crack as well.

I also bet a thin epoxy would be a better adhesive... you might not even need special copper sheets.

Why not just use the white/semi transparent FR-4 board?
Looks the same and it FAR more durable/drillable/easier to work and make.

[McSpunckle]

I've never seen FR-4 that was nearly that clear. Although, I've also never seen it polished up... I guess it is fairly transparent.

THIS MUST BE INVESTIGATED.

But the glass is totally clear. Which looks super awesome.

[John Lyons]

In the video the glass isn't clear other than where the glue/? chipped off.

He covers it with poly and it makes it completely clear. Could be done with the fr4 as well?

[John Lyons]

Ah, ok...must have missed that bit.
The "white" Fr-4 is always a bit frosted.
