Hey Jan,
What's up with the width/resizing of that picture towards the top of the page? Is it because it's imbedded? Can we fix it, or does LetterBeacon have to? (Not have to, I mean "can")

Thanks for those links Jan, I'll have a read of those when I get

I'm so glad you got it working LetterBeacon. Very Happy
Don't ever be worried about asking questions and learning the basics.
It turned out to be just like I said a few posts ago, "something which, as a new builder, you misunderstood, and Jan and I had taken for granted."
The connections on a 6.5mm socket! Laughing
This is actually really great, as it demonstrates how the "hard" bit can easily cloud the "easy" bit. Which is a very important lesson in troubleshooting. I'm very glad you got the chance to learn it early on. Very Happy

Satisfying knowing that you got to the bottom of it hey?


Definitely! I learnt so much building this project - not just how to use a stripboard (as I'd never done that before), but also how to troubleshoot, how to use a multimeter, how easy it is to overlook things!

Another quick question: I've got a linear pot as my volume control - should I replace that with an audio taper pot? Is that the same as a log pot?

It resizes automatically in my browser - I can probably remove the pictures now though if that's easier.

Yeah, audio taper, log, A. They are generally better for that type of volume control.

Did you know, (well you do now Laughing ) that linear pots have a "B" suffix, and that the "C" suffix denotes an anti-log pot. ie; a log pot around the other way. C pots are actually quite rare these days and hard to get. If you see one in an old whatever, rip it out. They are like hens teeth.
I think it was Mosc who was telling us that originally the linear taper was "A" and the log was "B". Then, at some point, obviously to simplify matters Rolling Eyes , they swapped them!

I believe that if you look carefully you will see that not all manufacturers today use the same convention for A and B. Just a warning -- make sure you see the actual words "log", "linear", etc., when you order a pot. If you have one laying around that you're not sure of, measure it.

Very Happy

I think he was referring to the large photos I posted on the other page. I've taken them down now.

Ah yes of course, those loaded pretty large before they were scaled down here as well.

Yeah, on mine they never scaled down at all. The page just stayed about 3 times wider than normal. I wondered if it was because they were embedded or a different type or both.
