Daniele had it do my portrait at DjangoCon last month and it turned out pretty well despite the fact I'm so hairy! https://twitter.com/fwiles/status/1177018222987448321
Judging from the pic, I'd say "Hairy" is something this plotter does well. It's a neat toy and a cool hack, but it's not useful for a lot except artistic sketches.
This looks like great fun, but I'd prefer to make something where the output is a little more precise. Does anyone know of a DIY plotter that's a step up quality wise from this one? Or maybe a site or community that lists similar projects?
The mechanical construction also introduces imprecision.

Also don't discount polar style hanging plotters they can be tricky accuracy wise due to sway, which i've seen countered both by decreasing plotting speed and by working the potential sway into your design. Just a quick search turned up this https://www.hackster.io/fredrikstridsman/stringent-the-15-wa.... You can start small like that and then improve components along the way. Swapping the string for beaded cord or timing belt etc. They are patricularly interesting drawbots because if you want to plot a larger area you can just spread out the motors and add more string.
Where can we buy a Pi and three servos for $14? That sounds darn fun.

Shipping might go over $14 though.

did you have a belt across your face?

A Raspberry Pi Zero is $5. SG90 servos are $1 on AliExpress. A separate power supply is recommended for the Raspberry Pi so that's what you can buy with the rest of the budget.
As far as I can tell, the real ones have four screws in the base, and "TowerPro" printed into the plastic on the top. The fakes have two screws, no brand name moulded into the plastic, and inevitably stop working quite swiftly.
