I spent so much on Batteries. Remember that thread I did with the battery connectors? I think that was my first stickied repair thread... That was one f*cked TE. Leaked all over and burned the chipboard..
That was also a horrible thread, lol. In that I used aluminum wire and was a n00B.
I think that was the TE I sacrificed to make the first fidget spinner.
EDIT: THAT DID NOT HAPPEN
