Homebrew PCBs

Aluminum boxes? Even better, I chuck a stub of a pencil with one of
those replacement erasers on it in a drill press. Then with the drill
on slow or medium speed, press it down in overlapping circles all over
the aluminum. Just press and up again, don't roll it around. Ends up
with a great brushed aluminum finish like on the cowl of the Spirit of
St Louis.

Spray coat it clear the instant you are done, or it turns grey
everywhere you touch it.

You can also make enclosures out of doublesided PCB. I made a small
metal detector, the body of the case was a PVC endcap and the
faceplate was a doublesided PCB chunk. I used the brushed circle trick
above, rubbed on some lettering and clearcoated. Looks beautiful and
very professional.

Practice your plastic welding skills! Build your own enclosures from
sheet plastic.

Or cast them. Expensive if you are only making one of something, but
great if you are going to do a dozen or a gross of something. I have a
list for that, too. ;')
