    I know you all are getting tired of the WiiBoy, it's been like 3 years and I'm still not over it. That's too bad :P

    The WiiBoy rev3 began January 2018 and was built for showcasing at MGC. It was completed but with little to no time for development, it felt very rushed. A year later I will be continuing the same portable again for MGC 2019.

    The WiiBoy is relying on a single USB-C port for PD charging and 2.0 data multiplexing (internal usb drive). So far it seems seemless.

    Though I have to give credit to @Aurelio for guiding me through the I2C registers on the chip. The datasheet was a bit confusing to me and they don't come out directly and tell you which configuration bits you need to set. After taking a dump of the registers and referencing some of the example code, Aurelio pointed out to me how to format the data. The voltage/current parameters are 10bit values divided into 8bit registers in little endian format. Thanks!

    I'm at the weird point where I need to finish the CAD to make the PCBs but need to finish the PCBs to finish the CAD. After getting through the 6 custom pcbs required, I threw together a highly functional test fit. It's given me a good direction of what I need to improve next.

    My favorite part of the rev3 is the CAD improvements I can make like the new comfy shoulder buttons and stereo speakers.

    Woops, IOVDD is 1v8 NOT 3v3 :facepalm: Cut/Solder maneuver it is working now. It's not harmful but since using the I2S Wii audio, all the data came in as static lol though I was positive my measurements/code config was right.

    Well the internals are in pretty good shape. I need to figure out how I will do the case next. MGC is coming up quick.

    You have a bad habit of soldering wires to QFNs. That's not good

    It looks so clean compared to Rev1

    I love it. I'd like to make a WiiBoy someday, I'm already studying these pictures :D

    Built up a more functional prototype for testing. Seems just about ready to move on to the next step. I used a light pipe for the led indicator, it works really well. The led alone is too bright but the diffusion brings it to a perfect level. The on button and the volume buttons are on the side, I made them the same buttons as the Switch.

    Looks great! From the 3D designing to the electronic circuitry, your worklogs are always interesting to follow!
