Homebrew PCBs

Jeff,

I did not build the etcher I described, and as I now recall it wasn't
shop-made at all. It was made by Kepro Circuit Systems (now defunct). I did
have occasion, though, to replace the pump. It was around $20 (but . . .
that was about 1985!!!!). Here's one that looks about like the one in the
Kepro:

I think you can find them cheaper than at Capitol Supply.

Damn me if I didn't just find the Kepro etcher I used on eBay:

The one I used was the BTD-201, the second on that eBay page. There are
several pictures, none very good. The seller wants $489 for it!!! Maybe if
it was new, that might be reasonable (I wouldn't pay it--I'd spend a
morning at the hardware store and the afternoon putting my own etcher
together). As it turns out, this one is an absolute wreck!!

73,

Todd
