Does anyone have a resistor they don't need or know a local place where I 
can buy one?  I only need one, and it doesn't have to be exactly 100 ohm. 
I hate to buy 100 of them for $6, but maybe that's the only way.  I asked 
at Free Geek and they said they never have them.

I only need it because I want to use it for testing batteries, as shown in 
this video:

Any advice would be appreciated.

Thanks!
