Mains Regeneration...

[DocG]

We have a very annoying flickering in our LED lighting every once in a while, like a ripple in the mains. Our electrician doesn't know how to solve it so far.

Could a regenerator/conditioner/balanced mains supply/... be of help here?

(Sorry for the OT, Gazzip. But since there seem to be a couple of educated posters in your thread, I thought I might get an answer here. Actually, have you had any such issues in your building projects?)

LED bulbs have very low persistence compared with CFL and incandescent types. Are they on a dimmer?

Yes, most of them are on a dimmer.

Not much we can do about the low persistence, I guess, so is there a way to 'smooth the circuit'?

EDIT: could something like this be of help? Though I wouldn't know where to get it into the chain...

... and in the same spirit, I wouldn't buy audio from a hifi dealer

actually, the correct analogy here is "I wouldn't have my dealer repair my broken amp themselves", which doesn't negate Gazzip's point. Strawman detected.

it wasn't analogy, it was 'in the same spirit'

straw man fallacy detection defeated

unfortunately 'electronics engineer with a PHD in the field of mains regenerator' is required at this stage.

The intention here was not to disparage the worth of an electronics engineer's qualification, it was simply to point out that there is perhaps more to this phenomenom than an electronics engineer may be taught about/aware of/cares about.

Does a structural engineer care about their steelwork design on a molecular level? No, as long as their calculations prove it stands up then what is going on under the surface of that material and how it is behaving is irrelvant to them. They have done their job and the steel frame stands up. Same applies to electronics IMO - as long as the circuit works and the electronics engineer's calculation proves this then why would they look at the other electronically irrelevant stuff which may potentially be going on?

Maybe a UPS might help.

Yeah, maybe...

Ehr, what's a UPS, Cno?

It is an Uninteruptible Power Supply...which is basically a device (with a back up battery), into which you plug (usually) a computer. If the power drops, it cuts in quickly enough to protect whatever is plugged into it (provided it is spec'd big enough).

Its the very same problems that plagues different cultures in the world. Inability to CHAGNE. Stuck in the past, stereotyping & all that. I wonder where we would be if we took the approach of it can't work or change all the time. Properly in the stone age still stoning people to death. *sad*

If I bought one for my toaster would the bread brown more evenly?

Your post saddens me. What does this kind of a comment possibly add to the debate?

I see. I'm not sure I could plug the whole lighting of our house into such a device though...

Doesn't add anything. And it's not even funny. Mostly cos it's been done to death on here...

Sorry Doc, I misread your first post. I thought it was the LED on a TV. *blush*

It's a reasonable enough question in the context of placebo effects. It's just as likely to make bread toast more evenly as it is to improve the sound of an amplifier.

It can sometimes help if you fit one conventional incandescent bulb in the circuit to act as more of a load.

did you really think for a second ( of course you did) there's an 'electronic engineer with a PHD in the field of mains regenerator' reading this thread and willing to give you scientific explanation to back up your ' it does sound better' claim?

We need to wrest the task of designing our hi-fi from the hands of trained, technological professionals and pass it to those with more 'open' minds. These qualified electronics experts have been lording it over us with their 'science' for far too long!

That's an excellent thing to try. My electrician comes next Wednesday. I'll see if he can do that. Thanks, Trev!

Nope. What I actually said was that the jobbing electronics engineers on this forum know jack sh-t about the affect that AC mains may or may not have on the sound produced by hifi equipment. They know how to build circuits and that is all. They are not physicists and this is physics.

Indeed it may be total BS but at least it isn't misleading BS that may result in somebody wasting their money on something that cannot possibly work.

If anybody is able to give me reasoned explanation as to why "re/conditioned electricity" can work on a hifi but not on a toaster I will apologise

I didn't suggest for a second qualified electronics engineers should not build electronics. My statement simply identifies the material fact that "physics stuff" going on in the electrical background, which will not prevent their designs from working, is probably not going to concern an electronics engineer all that much.

That physics stuff does however affect what you hear from your system, so it most definitely should concern you as a hifi hobbyist.

Misleading BS like electronics engineers, who know NOTHING about physics beyond their VERY narrow field, dictating on this forum what people should and shouldn't buy?

Very right.

How many physicists know about good electronic power supply design? I don't doubt that a mains regenerator will have a positive effect on the mains quality going into you hifi e.g. zero DC offset to stop transformers from saturating. But perhaps we should flip the question around - why are some "hi-fi" products so susceptible to power line disturbances given all the care the manufacturer might claim they took in designing their product??

It's basic electrical knowledge. So basic that even you could learn it!

I'll give you a clue. An amplifier doesn't actually run from the mains itself, it runs on smooth DC. It will sound the same if it was run from batteries.

Or putting it another way, if you wash your food do you believe it will make you run faster?

Of course not because your digestive system turns the food into an energy form that your muscles can use.
