    Worklog Kawaii

    I took a break from projects for a while, but I'm back and preparing for the release of the Kawaii. This weekend I tested the new RGB LED PCB, which has an ATtiny1616 and six SK6805-EC15 addressable LEDs. It's adhered to the rear shell with super strong 3M 300LSE tape. The LEDs...

    4" 640x480 IPS LCD Investigation (RG40XX)

    Good question! H-Sync and V-Sync were inverted on this panel compared to the 3.5" panel, but that may or may not break compatibility with UT-HDMI035. The NV3052C datasheet doesn't seem to mention sync polarity, so maybe it can handle either type. Worst case, you could slap an inverter on the...

    4" 640x480 IPS LCD Investigation (RG40XX)

    In January, I noticed a recent Linux kernel patch for the LCD used in the Anbernic RG40XX series of handhelds ( YLM-LBV0400001X-V1 ) https://lkml.iu.edu/hypermail/linux/kernel/2411.0/04250.html The panel part number prefix is YLM, which stands for Shenzhen Yangliming Electronic Technology...

    Model Sega Game Gear Console Scan

    I tested it on multiple Google accounts and it works reliably. How much free Drive space do you have? You won't be able to make a copy if you don't have enough room for the file.

    Worklog PS3 R&D Thread

    Welp, it happened. A new Raspberry Pi Pico based modchip has been announced by aomsin2526, called BadWDSD. It exploits the XDR DRAM's serial debug interface to write arbitrary code into memory. This has opened the door to persistent CFW on PS3 Super Slims. This new fork of Cobra CFW is being...

    Question Wii U turns on but no video output – forgot C194 capacitor

    The console will boot to the home screen without the Wi-Fi module connected, but it will freeze when loading a game or entering the system settings menu. It's unclear what exactly you've done to the mobo-- did you install and then remove a caféflex? The flex does not hold up to repeated reworks...

    Question Wii U turns on but no video output – forgot C194 capacitor

    Hi! C194 is not required in any way. You're supposed to remove it when installing caféflex. Is this an untrimmed motherboard? If you can, please share clear photos of the motherboard and explain what all you've done so far, including your softmod setup.

    Question Battery Life Ashida

    2.5V really is the industry standard cutoff voltage for cylindrical cells. A few cells have cutoff voltages of 2.7V or so, but they are outliers. The most common DW01 protection IC, used in virtually all eBay/AliExpress PCMs, has an overdischarge threshold of 2.4V - 2.5V. A threshold of...

    Question Battery Life Ashida

    Hey, this isn't a direct answer to your question, but I hope it's helpful for you and anyone else trying to crunch the numbers on portable battery life. The key thing to know is that advertised 18650 and 21700 cell capacities are calculated based on a full discharge down to 2.5V. The PMS2 uses...
