Found an Old Working Buck Driver, Help Me Identify It!

[hoo7h]

Hi all!,

I was digging some more in my old laser box, and I found this driver that I bought way back (2012 or so). I remember that it is a buck driver. Not sure who made but its one of the old people on this forum. Names I remember are Mohenburg, Lazereer or Cajunlasers. Or It could be Survivallaser. I can't remember which one but hopefully one of you will recognize it. I tested it with an old diode I also found, and it worked, and so did the diode! The output was kinda of weak but I am not gonna drop the towel yet on it.

Anyway, here are some pictures of the driver:

Any information would be really appreciated,
Cheers,
H

Hey man, please resize/crop those pics, they cannot fit screen even on computer monitor comfortably. You can always check preview of the post if it is comfortable to see.

This is really helpful, thank you so much!
Do you happen to know if the driver is ground positive or negative? And is the empty area bellow the driver good for a positive battery contact or a negative battery contact?

I apologize. Should I crop them on my own computer and then upload them again, or is there a function I can use?

 

[Radim]

I'm affraid there is no such a function on LPF yet. You need to crop/resize it on your computer and put the "LPF convenient version" of the image between BB IMG tags. You can edit the original post accordingly.

Can't see the pic... It is 4 times larger than my
computer screen... Which means that your text
is just as wide.
Default Pic size on LPF is 800 X 600 Pixels...

Not all members have 50" monitors...

As a once great member once would of said. You should buy a bigger monitor. :crackup:

Or maybe cinema projector - just to be sure all pics on LPF will fit. :crackup:

 

[CurtisOliver]

That could do, or just do this.

Me want!!

:drool:

 

[CurtisOliver]

Lol, it would be nice to have thinking about it.
But i'd prefer this setup. It's cleaner.

Anyway, better not derail this thread.

If you did the search as I mentioned on the LPF custom search you would have found the instructions with everything about it.

Who needs multiple monitors when you can have this?

Yeah I just assembled it. The diode is dead . But I think the driver is working fine. I decided to change the old leads and it sooooo hard to soldier the positive output and the negative output without having them soldiered together. I hope that I didn't damage the driver with the heat. I might just have someone else soldier it for me.

Thank you for your help!

Brilliant widescreen monitor Diachi. See Jerry, that’s the obvious solution to your problem.

 

[Pman]

Probably didn't damage the driver with heat but maybe check that the components still have good solder connections plus make sure your solder didn't make another connection to something else. I personally check my work with one of those 10x loupe things that you fit in one eye. You can get a cheap set at Harbor freight.
I mostly use my note 8 here although I have used my 9' projector screen and frankly its all relative to how close your eyes are to the source and resolution. I dont really like regular tv on the big screen because they only broadcast in 720p or 1080i and blowing up that resolution that big doesnt give the greatest picture. Amazon, Netfl8x and of course bluray look great. I was surprised how crappy a regular dvd looked but 480p doesn't up convert too well. Looking forward to one day having a 4k projector and not just 1080p.
Guess I'm not helping with the derail.
