    Nick Gillard Launches 62mm Pico-Mac-Nano: Raspberry Pi Classic

    Key Takeaways

    1. Nick Gillard has created a tiny functional Macintosh Classic called the pico-mac-nano, measuring only 62 mm tall, using a Raspberry Pi board.
    2. The pico-mac-nano runs a modified version of the pico-mac Macintosh 128K emulator and is available for purchase online for around £56 (~$75).
    3. The project faced technical challenges, such as adapting the display resolution and color depth due to hardware limitations of the compact design.
    4. The device features a 2-inch LCD display and connects to keyboards and mice via a USB-C splitter cable, with a custom 3D-printed case.
    5. Beginners interested in Raspberry Pi can find a helpful guide on Amazon to assist with starting their own projects.

    Nick Gillard has introduced one of the tiniest functional Macintosh Classics, standing at only 62 mm (2.44 in.) tall. This innovative project utilizes the compact WaveShare Pico Zero Raspberry Pi board, which runs a tweaked version of the pico-mac Macintosh 128K emulator. You can buy the fully assembled pico-mac-nano from the 1-bit rainbow store for £56 (~$75). For collectors, there’s a boxed edition available for £78 (~$105).

    The World of Macintosh Emulation

    Macintosh emulation has existed for many years, with passionate fans running the operating system and applications on various devices, from desktops to tablets, often employing Hackintosh techniques. Interestingly, the only touchscreen Macs that can be found today are PCs running macOS. The pico-mac project effectively emulates the original 128K Mac Classic using Raspberry Pi boards.

    Crafting the Pico-Mac-Nano

    To bring the pico-mac-nano to life, Mr. Gillard employed multiple hacks and modifications to fit the functional components into the tiny 3D-printed case. One of the main challenges was addressing the hardware limitation of rotating the display frame buffer to accommodate the 2-inch 480 x 640 pixel LCD display. Due to the restricted processing bandwidth, the native Mac display resolution of 512 x 342 pixels could not be implemented, so the pico-nano emulator was adjusted to output 480 x 342 pixels, which worked out just fine.

    Technical Challenges with the LCD

    The LCD panel requires an RGB input of 5 bits for red, 6 bits for green, and 5 bits for blue; however, the total 16 bits once again surpass the available hardware bandwidth. The solution involved adjusting the two most significant bits of each color channel, which greatly lowered the total bits needed to operate the display.

    The custom interface PCB and case were made using 3D printing, which made it easy to connect the LCD to the Raspberry Pi board. The USB-C port on the back of the board provides power and connects to an external keyboard and mouse using a USB-C splitter cable. The modified pico-mac emulator operates through the rear-facing microSD card.

    Getting Started with Raspberry Pi

    For those new to Raspberry Pi projects and looking to dive in, there’s a helpful book available on Amazon that can guide them through the basics.

  • Use Your Steam Deck as a Wii U GamePad Replacement Now

    Use Your Steam Deck as a Wii U GamePad Replacement Now

    Key Takeaways

    1. The Wii U has become a collectible item despite poor sales and issues with the GamePad.
    2. The limited game compatibility means most games require a functioning GamePad, with no official replacements available.
    3. An open-source project called Vanilla aims to replicate the GamePad’s functionality for various devices.
    4. Vanilla supports devices like Raspberry Pi and Steam Deck but currently has limitations with certain wireless adapters.
    5. The reverse engineering of the GamePad protocol helps extend the Wii U’s lifespan and provides alternatives for users with broken GamePads.

    The Wii U may not have done well in sales, but it has turned into a collectible item, even if that wasn’t the original plan. One major issue with the Wii U is a malfunctioning GamePad, and when it breaks, the console becomes nearly useless.

    Limited Game Compatibility

    Although few games can be played without the GamePad, this selection is quite limited, and there has never been a way to buy a replacement from either Nintendo or third parties. This leaves only the second-hand market as an option for those needing a replacement.

    Exciting New Alternatives

    Fortunately, if you own a Wii U with a broken GamePad—or if your GamePad is still working and you want to maintain it—there is now an open-source alternative available.

    Vanilla is an ongoing project that aims to replicate the Wii U GamePad’s functionality for various devices like the Raspberry Pi, Steam Deck, and Android. It relies heavily on low-level access to Wi-Fi hardware and has a long list of devices that it supports or does not. Currently, the ROG Ally and Ally X (which you can find on Amazon) are not supported due to their MediaTek MT7922 wireless adapters, but there is hope for a resolution soon.

    Additional Compatibility

    There is also a version designed for the Nintendo Switch, though it requires a Broadcom firmware patch or an external Wi-Fi adapter, likely needing a modified Switch as well. It should work on a variety of Linux-based laptops (with Windows support on the way), as long as the Wi-Fi hardware is compatible.

    The achievement of reverse engineering the protocol, especially given Nintendo’s closed-source hardware, is significant. It not only helps extend the lifespan of the Wii U for those with faulty GamePads but also offers the broader community options to keep the Wii U operational, despite Nintendo’s attempts to phase it out.
