I hope this is the right place to post this. I was at Radio Shack last weekend and found that they had their PCB Etching Kit on sale for $2.99. I bought the two they had and then When to another store and saw three more but I didn't know what I would do with them all. I know I want to try to etch 3 new strobe boards for my $6 strobes that the boards cracked or were damaged. I think It's going to be a fun challenge once I finish up Repairing my led strings. Then I have some north pole lights to change out the globe socket to rbg.
