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 .
