Zach Hipps off of byte sized engineering has built a giant 12x scale Raspberry Pi 3. It looks great and, even better, it’s fully functional!
Zach worked off a model of Raspberry Pi 3 on the Fusion 360 software platform. He 3D-printed large-scale versions of all the components; the print job took over 150 hours and used over 5kg of PLA filament.
Everything was then mounted to a three-quarter inch piece of plywood pretending to be the PCB. Once that had had its corners rounded off with a belt sander and been given a Raspberry Pi green paint job, it was time to add all the other elements.
To make sure everything went in the right place, he taped off the plywood PCB into sections, using paper to lay out scaled-up measurements based on a real Raspberry Pi 3. The 3D-printed USB and HDMI ports were spray-painted to give them a shiny chrome finish. Then he marked out the GPIO pin locations with a drill and hammered in thin sawn-off metal tubes where the pins would be on a real board.
A laser cutter marked out all the lettering on pre-laid strips of tape. Then Zach cut out the letters and used the tape as a stencil to fill them in with white paint.
Once all the arty crafty jobs were complete, it was time to make the giant Raspberry Pi fully functional by routing all the connectors from a real Raspberry Pi to the corresponding 3D-printed parts on the oversized wooden board.
This took a fair few extension cables for USB, ethernet, and HDMI, along with a LOT of soldering.
Zach: we don’t know why you did it, but we’re glad you did.
A noble tradition
This isn’t the first enormous Raspberry Pi the world has seen. We’re reminded of the Raspberry Pi Infinity+ that Michael Castor and Christian Moist made for MCM’s booth at the Bay Area Maker Faire back in 2016. And of various giant Raspberry Pi cakes at events down the years: less functional, but more delicious.
