I agree, very tidy! Kudos.

Do you need a bit of insulation between the edge of the board and enclosure? If the board can move at all it's fairly easy to short the traces.

And I feel your decal pain after the struggle I had with the last one. I did look into making silk screens, but was disappointed when I learned that the process permanently sets a screen to one design (or one layer of one design). Great if I wanted to crank out 20 identical pedals, less great for my experimental 1-off designs.

No, you can strip it off really easily. That's how I picked up all my fabric screens so cheap - the lady who owned them didn't know she could strip them, so once she was done with her shirt run she sold them for $20 each!

The one thing to note though is that the stripping chemical is often tied to the emulsion you use to set the image - different brands don't usually work with each other*. In cbr, you can coat a screen at Megalo for $5, and strip it for $2 (there are other fees too - hire, etc). If you're doing it at home the stripper I use comes as a powder that makes up a huge amount of liquid when mixed. I don't know how much it would be per screen but it would be $1 or less.

I usually do a few pedals at once, so I can get three or four stencils on the one screen, print them all and then strip it.

*Having said that, there is an ultra-caustic process that will strip anything, so if you find a good second hand screen but don't know what they used to put the image on it is still possible to get it off, it's just gross.

Good to know. None of the YouTube videos showing the homemade UV exposure method mentioned that part. But it does look fairly easy to make screens from some pine, mesh and a staple gun. I was thinking something A4 sized would be good for pedals. Also hoping I can do it more cheaply than the kits from Eckersleys by shopping around on eBay.

Thanks mate, yeah I will look at that when I get in to do the biasing and make the board a permanent fixture. It's currently sitting in there Blu tacked to the top of a plastic milk bottle for some clearance. Hot glue might be the answer. I just need to get a hot glue gun.
