Default problem with flexdrive??

when it is operation there is a high pitched whine sound coming from the flex, is it repairable or is is broken?

thanks all,
stuart

Default Re: problem with flexdrive??

I remember hearing high pitch sound from the Ultrafire 3W Blue K2 Luxeon flashlight, it also had a boost converter inside.

I also hear high pitch from li-ion chargers all the time.

This is normal I think, I never had a flexdrive but so far all DCDC converters are making it.
Except my LM3410X drivers, but they work on 1.6 MHz, don't know about Flex or others.

Default Re: problem with flexdrive??

Looks like i got the same problem as you got, when i turn my pointer on, its like 4-5 secs on full power not making any noise, then it seems to only run on half power and theres the high pitch tone coming from it. I think its just empty/almost empty batterys.

hotglue the inductor (think it has a 3R3 marking) It will get rid of it. I have had older video cards with chokes that squeeled when I overdrove them. A little hotglue over them and viola no more squeel. If that dont work give it a few gentle taps.

Haha

Inductors are known ti vibrate a lot and if they are not soldered well, theycan jump out of your laser punching a hole in your laser host and your wall.
They must be hotglued.


Just Kiddin', no offence!
But what do you mean by hotgluing it...
On what kind of logical principle does that work?

I was just kidding around, but asked seriously...
How could they possibly vibr... hold on.

There is some electric current going through the coil ...
It generates some electromagnetic field.
Is it possible that it actually pulls and repels from Earth magnetic field?

Just a thought.

BTW, I started writing my reply exactly after you posted nothing other than "hotglue it " , without all these additions in later edit.
Only when I posted I realised you added something new.
Apologies for meanie face !

Default Re: problem with flexdrive??

it isnt with me i sent it off to morgan to build it before i sent it off to him i tried to build it and failed. when i connected the diode one of the leads came loose and LED'd my diode also after the lead broke away from the driver, it was momentarily operated without a load.

morgan is hearing the high pitched whine and the driver has LED'd two of his diodes.

The driver could be doing something weird.
PM Drlava and chat with him about it. He will know the answer.

Default Re: problem with flexdrive??

I have had this problem before with 3 different drivers.
One squealed because of a bad battery supply.
One squealed because of a cold solder joint at the + input.
One squealed because the momentary switch did not make good contact.

I have never received a defective driver from Dr.Lava. In all 3 cases of malfunction, it was user error or bad components in the setup... and every time it was fixed with a little troubleshooting.

As Greenmechanic suggests, Dr.Lava will be able to help you out.

Default Re: problem with flexdrive??

Well ..... it works at 1,6MHz ..... there's no way that you can hear 1,6MHz oscillation (except if your name is Clark Kent and you line in Metropolis )

Must be a secondary oscillation caused from some other thing ..... or you're using it for too high current, or, more probably, you're trying to use it with a BR diode that have too high VF (remember that these boost drivers have a maximum output of 5,5V stable, using them with diodes that have higher VF, they works out from their safety limits ..... sometimes they still work, sometimes not .....


Edit: yes, also bad switches and unsure contacts can be a problem, with flexdrive ..... using "scratcky" switches, you can easily cause spikes that can kill a LD .....

No way a switching can cause some spikes that interfere with normal driver operation, that is what input capacitance is for.

So Flex is with 1.6MHz switching also?
Weird.
See my theory of interference with Earth's magnetic field... Few posts up.

Weird.
See my theory of interference with Earth's magnetic field... Few posts up.
I dont think its with earths field it prolly just the ferrite core of the inductor.

I don't get it.
What does the core have to do with anything? It does not move in any way...

Also, what about the chargers? I can hear high pitch noise from all chargers also!

This is one weird problem we have here...
