My friends,
My apologies for requesting the locking of my thread concerning LED's and PPI's.
I was in ignorance of the procedures for forum protocols regarding solved questions.
I therefore thought that locking was the correct method.
Regards, Peter.
Peter it was your thread but by keeping a thread open it helps other further down the line to ask other questions about the subject.
No probs, Peter. All cool. :thumbsup:
You did nothing wrong Peter and your request was made with the best of intentions and that is why I locked it at your request.
cheers John.

Yes !
I dont think we got to the bottom of this reverse breakdown stuff and I was going to ask some more about it, but I dont think I dare now :(

Just go for it Malcolm nothing to do with I dare you, you see I might learn something new. ;)

OK Malcolm - you asked for more info - get your teeth into this....
I found this link which talks about what actually causes reverse breakdown. The majority seem to think its the current/power dissipated by the diode when reverse biased that causes the breakdown, but no one seems to have established how much power is required. So, in your circuit (or was it Malcs?) with a resistor in series with each diode and the two sets connected in parallel in opposite polarity the resistor in series may limit the reverse current sufficiently to prevent damage.
The article also reports a huge variation in breakdown voltage, often much higher than the speced 4 to 5 volts. Here's the link - enjoy

Peter you're such a gentleman, I love reading your messages even if they have nothing to do with what I'm up to!
If life (in general I mean, it's all very friendly here in the NGF) had more petercharlesfagg's in it, it would be a much better place.
Cheers sir, keep posting!

Bob, I have no wish to belittle your efforts, they are praiseworthy, but may I suggest like our mutual friend that starting a new thread might be a better idea?
Warmest regards, Peter.

No problem - perhaps one of our illustrious moderators could stick this bit of the thread where they like (figuratively speaking of course!!) and let us know where they've put it. Then we can carry on with our electronic musings for as long as we like or we find something good to watch on the telly.
:thankyousign:
Oh! What wonderful banter between friends!!! :NGaugersRule:

MODERATOR! Mr Austin just used the words 'good' and 'telly' in the same paragraph! Is that allowed on this forum then?
:no:

Can some one explain to me the word Telly?
It's that glass box in the corner of your living room, Geoff.
I've no idea what all this rambling is about but I thought I'd join in.

The 'what' of it is easy enough, but the 'why' of it, well, no, not really...
But then, OK, I'll say no more coz I ain't got one. I reached a point many years ago when I realised I was spending way too much time gazing into a silly screen and decided to get rid of the telly and get a computer - no more gazing into... Uh, hang on a minute... OK look, I'll get back to you.....
:) Hehee !
I think we are all refugees trying to get away from telly trivia.
Although, she did alert me to "Sheds" last night, which contained two of my fav persuits, model railways and astronomical telescopes, except neither of mine are in sheds - yet ;)

Oh... My... God... Splod. Buy another TV and this time turn it on before you gaze into the screen... You might be pleasantly surprised. (But probably not!!!)

Is that an analogue dot or a pixel Geoff. If you've got a dodgy pixie (sorry pixel) you should consult with the elves and fairies to get it fixed...
You can fix analogue dots by a little blob of dark coloured ballast over the blob!!
Hope you find this fix useful.. Just going to get another glass of vino. Oh sugar!! - bottle is empty.

I've got one of these Smart TVs. - but its not smart enough to turn off when there's rubbish on. I agree about Dad's army - you could watch those for ever. Not a sign of smut, just innocent humour. Another goodie is last of the summer wine. I don't think Mr Splod could have seen these wonderful progs.

There was a question about the good life on Eggheads tonight, he was young and got it wrong !
What's that you say ? Me - watching Eggheads ??

I think you can get arrested for saying things like that Mr. Splod. I always thought she was a very nice lady. I really had no interest in what she did with her funny shaped vegetables. They taste just as good as normal shaped vegetables.
A funny shaped vegetable counts just as well as one of your 5 a day. Just remember that!!!
