so uh apparently i finished the whole picture and forgot to fix a huge flaw
but after some art surgery, hopefully it now looks like sea is turning around and not, like, folded in half
also i made the darkness a bit less stark so you can see what's going on
(again, huge snugglefriend is seafisheater on twitter)
wondering about good ways to use the Sun to get some portable heat for various purposes
my little workroom here is in a basement and it's always kinda cold, even on hot days
was shopping for a small space heater to aim at my legs or something but bleh, wouldn't it be cool if I could store solar energy in some way
@Alyx Right! With a little Lord of The Flies and Quest For Fire thrown in! It’ll happen.
@Alyx There are several works (I guess they work that way...), like BASE (Uni Bielefeld) or CiteSeeX. I''m wondering the same, btw.
sorta thinking of optimizing for semimicro scale work by going with a lot of "disposable" plastic ware that I would reuse. washing pipette tips and plastic tubes and stuff like that is tedious, but it beats the heck out of dealing with glass
spectrophotometer stuff
trying to work out color-reaction methods for calcium and magnesium would be cool because then that gets me an easy way to estimate water hardness. I did find a mention about using rhodizonic acid for estimation of calcium, and there's gotta be others
found an _indirect_ method based on precipitating calcium as oxalate, then gauging its oxidation by potassium permanganate. cute, but not exactly simple
spectrophotometer stuff
getting my new toy is pretty exciting, though. it's just a student instrument but still, it opens some doors. trying to decide what might be some good easy stuff to try out first
might need to get some supporting equipment first, come to think of it. but I can at least try the machine out with some stuff I already have
I once did spectrophotometric determination of iron(III) as the reddish salicylate complex because salicylic acid was easy to obtain
