Today i explored a part of the woods i havent been to yet. i consider these woods almost completely explored. it is surrounded by town unfortunately. i hope to venture out to other bigger forest very soon, however having woods this close to my house is really nice too.

today i was in my shed and saw the Voltaic Pile i'd made when i was 8-9 and wondered if that battery chemistry was rechargeable or if i could make it rechargeable by changing the electrolyte. simple answer is yes.
a Voltaic Pile doesnt actually work too well with a sodium chloride electrolyte. upon charging and discharging the plates corrode a lot. whereas with an epsom salt solution it only corrodes the plates minimally then by applying a charge you can reverse the reaction on the plates.
each charge/discharge cycle does create a small amount of Copper Hydroxide witch falls to the bottom of the cell but it is such a small amount that i could prolly get many cycles from this battery before the plates fully corroded.
this cell's terminal voltage is about 0.8v after sitting for a while and has about 7mah of capacity. it would be interesting to experiment with this battery chemistry more if only it would supply more amps and a higher terminal voltage.
the song is "Lung Bubbles" by Professor Kliq.
video still didn't come out how i wanted but fuck it i'm not spending another 8 hours on it haha.
