    Very impressive work! I especially like how you retained the metal over the GPU to help shield it from magnetic fields.

    I love your idea for creating a series of carrier boards for the power electronics. I did something like that once. Anyway as for scraping the solder mas from the USB traces, I would refer to the old PSP Undiluted Platinum installations. That mod chip required soldering wires directly to the...

    Have you done any browsing of Texas Instruments devices?

    build battery level

    Well you have to use a BMS board, otherwise you run a very real risk of melting your device. But all that aside, what you're looking to construct is a circuit which includes a voltage senseing ic of some kind, which will be able to communicate with, or directly provide a programmable GPIO that...

    build battery level

    So you want a battery level indicator that works independently from an off-the-shelf charge/discharge circuit? Also what configuration of batteries do you intend to use? number of cells, and how many series, how many parallel?

    Worklog An attempt to recreate the PS2 PCB

    This forum is a true delight, because we get to see such beautiful images of meticulous, carefully detailed work, into which a like mind has poured so much care and dedication. Your project is so incredibly ambitious, and it looks like you are quite equal to the challenge. If I may ask...

    So... If I'm understanding this... I should be okay as long as I use a MechaCon with the correct date code. Well it's actually funny you should bring this up (and fortunate), because I noticed a few weeks back that the MechaCons in the pictures in the title post, are actually the wrong date...

    Question [Last question UPDATED] Questions about my PS2 Slim SCPH-77004 project (SAMBA Router and SSD integrated)

    Any copper plane connected to the shrouds of the USB ports is GND, as is essentially the entire border of the board. If you have access to a multimeter you can find any voltage or common plane you want. Highly recommended tool for a newbie lol

    Good thinking!! I would never have thought of that solution. You're really smart!!

    In general you can't go wrong with anything from Texas Instruments. I believe the PS2 PSM all TI

    May I present, the network adapter and SATA bridge chip board: I am still trying to figure out if the CXD9731AGP chip will even work without the Ethernet chip attached, and whether i should ground the inputs, or leave them floating, or pull them high, or pull them low... It's a real...

    @Mister M You're absolutely right!! I will need to length match the traces for the RAM chip bus. Thanks for making sure I knew about that. I probably would have run into some pretty nasty performance issues otherwise. You're the best!

    So I know you said you don't care, but if you wanted to eliminated those little gaps on the front of your case, (I assume you print it face down) increase the initial layer flow by 10-20%. I find this makes for a cleaner surface when printing cases like these
