The unique Apple Macintosh laptop, launched in 1984, was elementary for ushering in GUIs (graphical person interfaces). It wasn’t the primary private laptop to characteristic 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 retrofit with a contemporary ePaper show.

The Macintosh Traditional II hit the market in 1991 as a low-cost mannequin, however it retained the design aesthetic of the unique Macintosh. It was additionally the final Macintosh laptop with a black-and-white display. 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 laptop. Curiously, Luna added an adapter to feed the output from a Chromecast system to the Raspberry Pi’s digital camera enter with the intention 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 are usually not appropriate with in the present day’s computer systems. To make them work with the Raspberry Pi, Luna turned to Arduino. He  used an Arduino Micro to 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.
