Traditional Macintosh will get an enormous ePaper show
August twenty fourth, 2022—
The unique Apple Macintosh pc, launched in 1984, was basic for ushering in GUIs (graphical person interfaces). It wasn’t the primary private pc to function a GUI working system and the concurrent Apple II nonetheless retained a extra conventional command line interface for years, however we largely have the Macintosh to thank for contemporary GUIs. So it’s applicable that Dave Luna selected to make use of an Apple Macintosh Traditional II to.
The Macintosh Traditional II hit the market in 1991 as a low-cost mannequin, but it surely retained the design aesthetic of the unique Macintosh. It was additionally the final Macintosh pc with a black-and-white display screen. Luna changed that CRT (cathode-ray tube) with a 9.7” Waveshare ePaper show. He additionally eliminated the entire unique PCBs and changed them with a Raspberry Pi 3 Mannequin B single-board pc. Apparently, Luna added an adapter to feed the output from a Chromecast gadget to the Raspberry Pi’s digicam enter to be able to present household photos saved in Google Images.
However there have been two elements that Luna couldn’t exchange with out ruining the look of the system: the keyboard and mouse. They utilized proprietary connection protocols and should not suitable with immediately’s computer systems. To make them work with the Raspberry Pi, Luna turned to Arduino. He used anto create an adapter for the keyboard and mouse. That runs TMK’s ADB (Apple Knowledge Bus) to USB Keyboard Converter Arduino library, which deciphers the indicators coming from the keyboard and mouse after which connects to a pc as a contemporary USB HID. Lastly, Luna programmed a customized Python script to show a Macintosh-styled GUI for the Raspberry Pi.
