I built another one, it’s always been useful to have 2 of my drawing machines.
PewtyBot 1.0 x2
PewtyBot 1.0
I’ve used this project as a stepping stone and modified it some. I can’t say enough good things about it, it propelled development forward significantly and I found it to be expertly designed. Too bad the project it now defunct. I had to find assembly documentation on archive.org.
I’m not sure I’ll document it as well as I have the tabletop plotter or the gondola one. At least not yet, maybe that’ll be a Christmas project like the other 2. I did port the same software stack, it would be a shame not to given the years of feature development that went into it. Of course we should use these features with lasers. It might also change drastically, I want to investigate what rotating mirrors could do for speed. Currently some of the moving parts of the machine have enough mass that their inertia causes inaccuracies when moving at high speed.
It’s nice to have things tidied up, the development machine was a mess.
Crutch Guitar
That’s right, crutch guitar. I got swept into the world of cigar box guitars trying to make Robin’s broken leg somewhat fun.

The bridge
On the back I added some metal nuts to act as washers so the string ends wouldn’t eat into the plastic.
The head could be adjusted a little but it’s good enough to play with the concept.
It sounds and works a lot better than I thought it would. And Robin’s way into it. Although I underestimated how hard it would be to play it without frets. It’s very much a different cat, people online make it look easy :).
