What Does a Hacker Do With A Photocopier?

The year is 2016. Driving home from a day’s work in the engineering office, I am greeted with a sight familiar to any suburban dwelling Australian — hard rubbish. It’s a time when local councils arrange a pickup service for anything large you don’t want anymore — think sofas, old computers, televisions, and the like. It’s a great way to make any residential area temporarily look like a garbage dump, but there are often diamonds in the rough. That day, I found mine: the Ricoh Aficio 2027 photocopier.

It had spent its days in a local primary school, and had survived fairly well. It looked largely intact with no obvious major damage, and still had its plug attached. Now I needed to get it home. This is where the problems began.

Copying objects in 3D


[Pulse 9] sent in a very interesting project he just finished up at an internship. It’s a 3D photocopier that scans an object and then mills said object into floral foam.

The copier is made out of material [Pulse] found sitting around – PVC, drawer slides for the X and Y axes, acrylic for the structure, and broken printer parts for the Z axis.

To scan an object, [Pulse] puts an object down on the bed and scans it with a laser and webcam. The images recorded on the camera are fed into MATLAB. The output from MATLAB is sent over serial to a custom board containing a PIC18F4620 that controls the axis motors. The spindle for this floral foam router is a simple drill; one layer at a time, the drill mills out the unneeded foam which can be sucked up by a vacuum when the object is complete.

Below you’ll find [Pulse]’s demo of his photocopier and a piece the local news did on the project. If anyone is willing to translate that story, feel free to do so in the comments.
