Re: From Member: where to get 2.5K resistors?

Hi Jack,

Again, I would confirm them with a VOM to make sure you will get the
tolerance you want/need. Of both are out of tolerance in the same
direction (say 950k and 1k425 = 2k375), your resistor would be more off
of 2k5 than if they varied in different directions (say 950k + 1k575 =
2k525). Again, if tolerance required is not more than 5%, a 2k4 is
already within that tolerance. a 5% 2k4 is well within the tolerance of
a 10% 2k5.

By the way, I am a Radio Control Model Warship Combat guy (see
http://www.ntxbg.org ) not an electronics guy. But, in that harsh
environment, you tend to learn a tad about pneumatics, hydraulics,
hydrostatics, mechanicals, electronics, materials and manufacturing,
modelmaking, RF, physics, some chemistry, a lot of history, navigation,
tactics, weather, etc. One of our guys took the knowledge he had gained
and designed an automated, self logging, remote sensing gas,
chromatograph for the oil industry. I have moved into programming
microcontrollers (the Picaxe series) to do what the R/C stuff doesn't
(without paying VERY high $$$).

It is also what brought me here. A couple of guys in our club are into
CNC, and I am trying to pick up what I can to move that direction
myself. Being able to CNC parts for the turrets/gun systems, not to
mention detail parts, would be REALLY useful.

Good luck,

Wreno
