Sometimes our electronics are too small for us to really appreciate all of their intricacies, but that’s not the case with this giant Raspberry Pi 3 replica.
YouTube creator Zach Hipps set out to make a Raspberry Pi 3 much larger than typical palm-sized computers. Through careful workmanship, he assembled a scale model 12 times larger than the real thing. And in the creative mind, his giant Raspberry Pi 3 actually works.
This giant Raspberry Pi is built on a 3/4 inch thick piece of plywood that replaces the computer circuit board. The traces of the circuit are all painted and Hipps spent over 150 hours and used over 5 kg of PLA filament to print the various parts of the Raspberry Pi 3, like its HDMI and USB ports. He made the large GPIO connector along one edge of the device from metal tubing.
Of course, plywood and paint will not transmit the electrical signals necessary for a fully functioning computer. So, Hipps attached a real Raspberry Pi 3 to the back of its scale model and made wiring connections between its ports and the larger counterparts.
Hipps wired the GPIO pins of a real Raspberry Pi to the giant GPIO pins of the enlarged replica – a fairly laborious process that required cutting a ribbon cable to expose its wires, then soldering individual cables together with the exposed wires in the cable tape and re-insulating each.
Then Zach mounted real working ports on their 3D printed counterparts and hooked them all together with extension cables going to the real Raspberry Pi 3, so accessories and cables could be plugged into the right places – no HDMI cables. massive is needed.
There are a lot of cool Raspberry Pi projects like this. While many take advantage of the computer’s small size, Hipps’ project is unique in going in the opposite direction. This isn’t the first time he’s achieved something like this, however, having already built a giant Arduino board.
