Re: Reverse polarity diode circuit

Yeah, I saw that after I ordered them on line. Tayda turns up 0 if you search polyfuse, which is what I searched for. Search "polyswitch" and they pop up. I always check them first as they often ship from the distribution facility in CO. The offer will still stand for anyone who doesn't need extra stuff on the order.

The better news, you can get them all day long from Tayda for 16 cents
each. But they only have 119,418 of them in stock.? To the US, shipping
from Tayda is only a week for their slow boat shipping. Tayda's minimum
order is $5, so for another $3 and change you can get that replacement nano!
