What are possible uses for weak batteries? Answered
A followup on my previous question, sort of...
I have about 150 old semi used 1.5v AA batteries that don't have enough juice in them anymore to power anything significant.
One can only have so many Joule thief powered LEDs, and it's a shame to dispose of them all.
So the question is, what would YOU do (*Pointing at you!*) with those batteries?
Thanks for any and all suggestions!
