Oh, in case you didn't understand "tolerance":

Even though your resistors may be marked as 100K (Or whatever), they
really AREN'T 100K, they differ by a bit. So you're engines are going to
differ, no matter what. Try swapping different parts out of the one that
doesn't perform as well untill it does. My .02...

7100 Wed, 27 Oct 1999 02:19:24 GMT [alt-beam] A few questions alt-beam@egroups.com "Steve M" Okay, I'm a newbie, so bear with me. I have a few unrelated questions that I
thought some of you could help me with.
1) I'm building a photovore, (using Chui's tutorial) and I was wondering,
which lead is the wiper on a potentiometer block? There are three leads and
by looking at the schematic it is pretty obvious to see where the middle
lead connects, but are the other two inter-changeable?
2) Just what exactly does a Digital Multi-meter do?
Thanks in advance,
Steve
