Then I stopped by the local stationary store and had a transparency made of my sketched board layout.

I used the components to determine the correct spacing.

Using the transparency and two positive photo resist boards, I managed to overexpose one, and underexpose the other.

I drew my circuit on the board (a little thicker) with a sharpie. This is the end result.

It's mostly intact but you can see places where the acid wash ate through the sharpie.

did you use the "bath" or sponge method to etch?
The bath method sometimes causes the acid to eat around/below the ink.

I don't want to be a dick but I seriously hope you did not post your full callsign in the OP. I now know the name and address of OP…?

While I don't think anyone on this small of a board will do anything, you need to treat your callsign with special care here.

 No.177

Hams have had to put up with psychos for decades (espech since CB came along..) Knowing a Call isn't going to provide a doxxing hazard.

The person who designed it is k3pgp. I hopefully edited out my callsign. I havent updated my new address with industry canada yet, so you would only have my name.
