Can these be for real? Five pcs for $1.69: http://www.ebay.com/itm/201574969988
I have a pile of 386 amps but I gotta try these out, that price seems cheaper than free. Small board.
Another noteworthy tiny board (practically microscopic at about 1/8" x 5/8"), is this 29-cent (OK, ten pcs for $2.89) Li-Ion battery protection chip, which claims to do it all. Overcharge protection, over-discharge protection, short circuit protection, overcurrent protection. I just got these in, will test soon. http://www.ebay.com/itm/162025038275
"When you make a thing, a thing that is new, it is so complicated making it that it is bound to be ugly. But those that make it after you, they don’t have to worry about making it. And they can make it pretty, and so everybody can like it when others make it after you."
- Pablo Picasso
