Resistor value for R29 on MSnS
Steve Lovelock - 25/3/07 at 07:17 AM

Hi,

I am setting up a wasted spark MSnS and have just installed the two VB921 chips. I have a query over the resistor value for R29 though as the 330 Ohm resistor supplied with my additional VB921 is marked differently to the resistor I have already fitted into R29 as per step 57 in the build manual.

The resistor in R29 has gold : red : black : brown markings whereas the 330 Ohm resistor supplied in the VB921 kit has Gold : brown : orange : orange.

My question is: do I need to remove this resistor and purchase another 330 Ohm resistor to replace it?

Resistor values are read the other way round, the gold is the tolerance value and it's at the end, so brown black red is 1k. Here is a good chart to allow identification, a lot of people use mnemonics to remember the colours but the only one I know is far too offensive to post

As to which one is 'right' for you, er..... sorry

Just had a peek at the V3 schematics and R29 is part of the accel LED circuit, shouldn't be affected by a second VB921 going in?

You're an abrasive twunt aren't you? You could have just said 'when adding a second VB921 it's driven from old accel LED output' and i've have gone 'ahh, i see, cheers for that', but no, you have to have a pop and insinuate i'm a thick twat in the process. No wonder you're popular.

Wind that ever popular brass neck in a bit please Mark.

Eh? I don't feel silly at all, sorry for not being at my absolute sharpest first thing on a Sunday morning. I don't have a problem with being corrected, you'd never learn anything if you did. What I do have a problem with is being belittled by an unnecessarily condescending comment. I mean, how hard would it have been for you to have not typed that first line? Really? If someone had said that to me face to face I would have told them where to stick it, it's just plain rude.

It's not what you say, it's the way you say it. Either you are so socially inept that you just don't see how your constant patronising would affect other people, or you do know and you're just a git.


BTW, sorry Steve, didn't mean for this to fly off on a tangent

Just to tone it down a bit, polite mnemonics:

Colours and corresponding values:
Black(0), Brown(1), Red(2), Orange(3), Yellow(4), Green(5), Blue(6), Violet(7), Grey(8), White(9).

Polite Mnemonic:
Bye Bye Rosie Off You Go, Birmingham Via Great Western.

I am sure there are others out there.

This colour order is also used for multicore cables (with the addition of Pink and Slate [Grey]).
