Check out this upgrade to give a Wii U a massive boost in power and functionality. Via Hackaday:
What’s in this thing this time around? Buckle up ’cause it’s a ride: an Intel M5 processor core M on their Compute Stick, 4GBs RAM, a 64GB solid-state drive, a 2K LCD touchscreen, Bluetooth, WiFi, a 128GB SD card slot, two 3.7V 4000 mAh batteries, a Pololu 5V,6A step-down voltage regulator, a Teensy 2.0++ dev board, a battery protection PCB, a USB DAC sound card, stereo amp, a USB hub for everything to plug into, and a TP5100 battery charging board. Check it out!
It runs Windows 10 and Cemu — a Wii U emulator — so virtually none of the console’s original functionality is lost in the process! The home button cycles through the joysticks’ coloured LEDs, and battery monitoring software safely shuts it down once the battery reaches critical — which takes about two hours when it’s being put through its paces. The LCD might seem like overkill, but it’s only 2.5mm thick, leaving enough space for the rest of the electronics while also having a more efficient power consumption.
