The Hobo Camp Fire Is going well #VIII.. Stop In!!!

[ezdays]

Good Friday morning, wow, another Friday, this is about the 88th this year so far. Well, it seem so anyway....

Watched the weather part of the news last night, video of pouring rain somewhere in the Valley, just not here in our area. Had some pockmarks on the windshield yesterday, still not enough rain to measure here.

Got my interconnect circuit board drilled and marked with a sharpie. Maybe I'll be able to etch the board today. It's a process that I've been through hundreds of times, just not at home with hand-drawn circuits and using an enchant formula that I found on the Internet.  If you see a big poofy cloud or some eerie glow coming from the NW Phoenix area, you'll know it wasn't the right formula for etching copper.

Have a great weekend and stay safe.

Don i have used commercial (10 % ) vinegar  in past for etching boards it is slow  though .

Thanks Jim, I found several sites that say a 2:1 ratio of Peroxide:Muratic acid works really fast. Got the stuff, I'll let you know how it works.

UPDATE: tried this mixture outdoors. The heat of the sun probably accelerated the process, but my board was over-etched in about 15 minutes. Still usable, but I did keep it there a little longer than I though it would take. We used to buy bags of ammonium persulfate, costs a lot and took way longer than this did.
