That's really great to see it used in Gatsby's documentation, I wasn't aware of that. And I like the way you say e.g. "Practical step-by-step guides to help you achieve a specific goal. Most useful when you're tryin

Thanks for the kind words! You are quite right, there are various things that aren't included in the scheme, that ought to be included in a complete set of documentation. Other examples could be: release notes (though you could include

Would be interested to know what the experience is of this in other companies, smaller ones as well as large corporations with masses of $$$$ swirling around.

Not with these servos or this mechanical arrangement, that's for sure. But, it's very interesting to think of ways to improve the precision of imprecise hardware, using only software.

It works fine with every kind of drawing implement I have tried: * pencil * charcoal * ball-point (needs additional weight on the pen) * roller-ball * felt-tip * fibre-tip It draws so slowly that there's no issue about waiting for the

I also use "background" or "discussion". Someone else here suggested "rationale".

That is interesting - my experience is the opposite, that how-to guides and tutorials are the most-commonly confused types of documentation. My aim is to make the serve totally different needs: * tutorials: I'm in charge (the teacher)

Thanks for all the interest and kind remarks this has received. I have updated the documentation substantially and included more photos in it.

Also it's hard to defeat hysteresis in the system, both in the servo motors (they have significant dead bands) and the mechanical arrangement of the arm/pen.

Be careful, a lot of SG90 servos are fakes. Below a certain price, they all appear to be counterfeit. 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

More expensive servo motors will produce better results, but past a certain point, they would require more power than the Pi alone can supply. The mechanical construction also introduces imprecision.

"not useful for a lot except artistic sketches" - what could be more useful than that?!

Turns, out, it's actually very reliable in practice. I'm trying to work out at the moment just how far I can go with more powerful servos: https://raspberrypi.stackexchange.com/a/104662/42583 . There are
