rmd: (whoah)
i got a call from one of my dad's clients the other night, looking for more paperwork -- i'd given him a box of stuff from my dad's office back in jan, but apparently there are some 941's missing. so yesterday i went to the cape with my neice and visited my stepmother and ventured down into the basement full of loosely constructed metal shelves full of questionably labelled boxes of paperwork that was mostly lumped together. found one for the restaurant in question and another labelled as being for the folks who bought the restaurant but actually appeared to be from the era i was looking for.

proof i have moments of smart: as i was picking up the boxes, i noticed the cardboard was really brittle and weak. so i very cleverly put both boxes into large garbage bags so that if either one broke while i was hefting it up the ladder/stairs thru the trap door up to the main floor of the house, i wouldn't have to spent the next hour picking up pieces of paper and wondering if i got it all.

i made it thru one of the boxes while my stepmother and neice were off running errands, and sorted out the few things that were misfiled. i still have another box to go through in the next few days before i can cart it all over to stoughton to the client in question.

hopefully this will be it for paperwork hunts.

i think the next step is to go thru the boxes in the basement, pull out things from the 1970s and 1980s and shred that. probably over the summer so i can do it with the basement door open and get fresh air in there.

meanwhile, i think i may go experiment with some home chemistry today. or at least experiment with resists. wtf is wrong with youdoit electronics that they don't have the press-n-peel resist stuff that you feed thru a laser printer and then iron onto the board?

i've been intruiged for a while with doing some home etching stuff. (i made some circuit boards years ago, but nothing for close to 15 years.) i_leonardo and the duck did some etching the other night, both with acid and electrically based etching. and that was fun.

so i picked up some ferric chloride at youdoit and experimented with taking a transparency printed thru the laser printer and ironing it onto the copper board. (the copper board was some roof flashing from the orange box)

it didn't come out great, but parts of it were pretty good. the resist wasn't as resistant as i had hoped in spots.

there are pictures.

parts that came out well:
