Frequency domain is made out of wood.
I have uploaded the code demonstrating it to Github.
You are very welcome to read the code and run it yourself. I hope you already have Python, numpy and matplotlib installed.
For just in case:
pip install numpy
pip install matplotlib
ChatGPT can generate pretty cool text or software. Mid Journey and Stable Diffusion can generate pretty cool pictures. But there is also Point-E which can generate 3D models from description!
I have generated something. Guess what it is?
My cat puked at a scratcher pad. I do not think it is washable, or at least I do not have a non-toxic puke solvent which would not destroy the cardboard. Or maybe I should try water? Too late, I have already disposed it and made a new one:
I have a CNC laser engraver with 1m x 1m bed and I decided to build an enclosure for it.
Here is the CNC: https://fun.balashova.com/2020/11/1m-x-1m-cnc/
And here is how the project started:
I have got a flux wire welder and this is my first project:
Bananas are just for scale.
I could of re-weld and re-polish all the imperfections, and do some finish, but maybe next time.
My takeaways about the welder. It is not a hand-help 3D printer or a glue gun, even though it spits the wire. You cannot (easily) 3D-print with it. Also, it is much easier to deal with thick material than with a thin one. It makes holes in thin metal sheets and pipes like a woodpecker. Also, you cannot safely weld most of the metal parts you see around because they are either galvanized or stainless of non-ferrous. Bummer!
I have built one more shelf in my garage.
Because Halloween is coming…
And because I had 3 scrap lights and some scrap plywood…
I have got a R-axis drive as a birthday gift.
It is just plug-and-play with GRBL controller.
And it is also adjustable
This is not Neje and not 80w. This is shady “40w” laser from Aliexpress.
Guess why did I polish off the corners like that?
Spinner size is limited by hand size. You cannot make it more than 7 bearing large, or you would not be able to spin it. Or could you?
Well, I can spin my 15-bearings spinner:
