    [QUOTE = "Nold, post: 25822, member: 1499"]Thanks mate... but you better watch out for your "PTHs".. when they come from china, they will likely be a ripoff! but IDK...
    ATM I'm waiting for my new 3D-Printer, as I was fu**ed off by the size of my case again... so I'll do something else :P

    As for pinouts, I already created the definitive DC trimming guide, so you might check that out ;-)
    https://bitbuilt.net/forums/index.php?threads/the-definitive-dc-trimming-guide.1925/

    Also there will be more DC action soon! :)[/CITAR]




    Dude, can you explain me better about my regulators in china?
    they're of bad quality, is that it?
    I waited so long for them ... =(

    And thank you very much for the guide, I had not seen it yet ... I'm in the middle of a PS2 project, but when I finish it for sure I'll go back to Dreamcast thanks to your guide ... Thank you! Your work is amazing!!!

    He just means that anything from China is risky because there is a good chance it is of poor quality. Are your PTHs branded TI? If so, they’re probably ok and you just bought from a Chinese reseller.

    I understood...

    Here are the photos of the regulators I bought:

    Are they of bad quality ?? Will not they work?

    I found these PTHs in a server junk, someone knows if they are usable:

    First pic has the Texas Instruments logo on the board. I’d say you’re ok.

    I’ve not seen the PTH in that last pic before. I’d recommend looking for a data sheet for it before using it.

    Looking at the datasheet you may have a problem with the PTH05050. Looks like it only accepts an input voltage in the range of 4.5-5.5V. This means you cannot use this module with a standard battery setup.

    Man, WHOA!

    Firstly, you are RIGHT. it IS the year for Dreamcast Portables.

    And secondly, DAMN, I'm about to try that DC board trim, probably tomorrow, I got a few DC's, but I need to get everything together. I'm a HUGE fan of Frankencasing (All of my portables are frankencased) and I refuse to do it any other way. You are doing a fantastic job. Thanks for keeping the DCp Dream ALIVE, bruv.

    i think i'm slowly getting into CAD... starting to love this parametric stuff! It takes much time to "program" but I hope it'll become nice to reuse & share :)

    btw,; waiting for my Prusa is even worse than waiting for a print to finish... <.< hope it finally gets shipped next week..

    Yea, i really like them, too! Used them for all my portables basically.
    I salvaged them from old Fujitsi Primepower 800 Systemboards back in the Gamecube days, since they have pretty much of the size of the GC Heatsink.

    Yea, as said above, i replaced the two onboard regs, too. You'll find more infos in the DC Trimming guide.
    Also you can't (/shouldn't) use a PTH080808 for 3.3v without replacing the onboard regs, too. Cause it'll draw to much current otherwise.

    I’ve been revisiting this thread because TrueSonic has been sharing his DC woes in the Discord. Saw this from the first post that I must have missed the first time around:
    So is it probable that my old ebay-found DC has a bad PSU? It occasionally restarts on its own. Usually if I leave it powered off for an extended period. Then once I have it going for a little while it seems more stable. I always assumed it was the disk drive giving out and that it just restarted as a means of crash recovery.

    Yea, this is actually a quite common problem with the DC. It's mostly related to a bad connection between the PSU & DC Mainboard.
