Taking a few suggestions and looking closely at how the pen meets the paper, I've adjusted the distance and angle closer to my taste:




I can write almost normally now. The rest should just be a matter of breaking habits, I hope.

Bluejay with ink-drop and fucked up back:


The back was a failed experiment, next time I'll brush it, not pen it.

Back to the stone paper. Please excuse the lines. Please excuse the everything really.

I'm not sure what kind of bird that is.

Today I continued my devolution from 21st-century science back to preschool arts-and-crafts by making a pop can pen, which is a cheesy version of a real thing called a "folded ruling pen". That's a very simple and surprisingly modern invention(1995) which allows really dramatically adjustable pen/brush strokes. Imagine a brush you could tune from 1mm wide to 20mm wide in the middle of a stroke.



Still figuring out how to use it. I don't think mine's very good, but it's all I've got until more nibs arrive in the mail.

I'm going to read the article, but first just note that "Robotic Helmet That Stops You From Breathing" would serve the stated purpose.

I haven't wanted to make or draw anything in a while. Trying to push myself out of that rut produced this nonsense.

I probably under-thought and over-engineered this Raspberry Pi mount. I thought it would be neat to either check the status of 3D prints or make time-lapse pictures of them.

IMG_4947_sm.jpg

This is what it's seeing:

im_0000_20180429_130909.jpg

It's part of my continuing trend to steal my son's Erector set as useful mounts for things. I made a mount for the large cable spool. This was also part of an attempt to organize my space. Right now, I'm not embarrassed to show you my workspace....

My personal favorite is the USB cable draped over the microscope and the door of the armoire - the PC which controls the 3D printer is about 2 meters to the left. The plan of record is to move

I should invest some time into cable management, but stuff gets moved around often enough that it's not always worth the effort.

I finally built something I wanted to do for quite a while: Chua's circuit.

It's a chaotic oscillator, which, instead of producing something incredibly boring like a sawtooth wave or whatever, creates a monkeyfighting, honest-to-god strange attractor. In fact, it's pretty much the opposite of a boring, well-behaved wave: it never repeats. It never does the same thing twice, which is pretty crazy if you think about it.

After doing a compact one on stripboard which turned out to be a pain in the ass as I was looking for shorts and everything, I did it again on perfboard with lots of space and laid out like the circuit diagram:



I immediately got the double scroll after turning the knob, which was a nice surprise:



About half the parts are from old junk like broken TV sets.

The sound file below is what it sounds like hooked up to a guitar amp, the high-pitched beeps at the beginning and the end are produced when the circuit is not chaotic, at the start there is period doubling which happens when the sound becomes more complex and then it turns chaotic as I turn the potentiometer knob:

I made my cat annoyed with me this week.



More so than usual, at least

So, on a whim (and a sale this month) I bought an "art lens" kit from Lensbaby. This picture was taken with the Edge 50 optic, which at lower apertures produces a thin slice of focus through the image.

I actually have some plans of pictures to take with this, but for now I'm just goofing off with it.

Also I made a V3 of my flashlight cover, which I made hexagonal, but probably won't work nearly was well as the round version. (It's much more fragile.)

Pictures to follow.
