    Post whatever happened to modifying a PS?

    I thought someone around here had found how to modify a computer PS to work off 12volts?
    Is it still being worked on as a project?
    if so, where?

    Cool

    Not to be a smart *** or anything, but I would imagine that they realised it was futile and gave up.

    I kinda figured that, it didn't seem like it would work out very well

    this thread has guys talking about rewinding the primary coil, and a guy called Presslab here talks extensively about what he did, involves a bit of hacking a you need a new transformer, but he made it work.

    I think I just might do that instead. It's just that a lot of people don't understand electronics, and a fair bit of knowledge is required in order to know exactly what to do.

    It might. But I do think the fact remains that it is really more trouble than it's worth. With all the modifications and time it takes, it may just be cheaper to spend the $75 US and get a DC-DC unit...Of course, that's just my opinion.

    If you can point me to a $75USD ATX power supply I will buy one RIGHT NOW.

    We're dealing with $165 right now + shipping for the only one that works, and *maybe* $92 for one that's new (but isn't as powerful and doesn't have -5V among other things).

    Rewinding a transformer isn't all that difficult. If you have the savvy to build a sproggy, you can modify an existing ATX supply for a lot cheaper, and easier, and get a lot more power out of it in the long run.

    I can't see spending $165 on a power supply. Maybe I'll go for one of the $92 ones (presumably cheaper with bulk buy), but even there for just 130W or whatever that's a lot of money for not a lot of juice.

    Cool

    Hmmm...ATX, I forgot. Unfortunately, I know of no inexpensive ATX supply...However, personally I would rather spend the $165 for a manufactured unit with a warranty. I did the DIY electronics stuff for a lot of years, and sometimes it is just more trouble than it's worth. Of course, that's just my opinion again...

    Yeah I'm starting to understand how you feel. However now that I've got a pile of parts and got overcharged by coilcraft, I might as well try to build something.

    If someone could give step-by-step instructions on how to easily modify a normal AC-DC ps to a DC-DC ps, I'd do it no problem... The problem is I'm not one to want to wind my own transformers. Too bad we can't find some remade like what would be required. (sigh)

    Does anyone have any current links to a page that contains directions on rewinding a transformer? Thank you in advance.
