An article "A Hippocampal Cognitive Prosthesis: Multi-Input, Multi-Output Nonlinear Modeling and VLSI Implementation" by Theodore W. Berger, et al.
(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3395724/) tells about a brain implant with 16 analog-to-digital converters and 32 channels of output.

I've been discussing it with Prozion (https://github.com/prozion) before and he has a very good question.
"How does the implant function at all with that amount of channels?"

The previous explanation from "Computational Cognitive Neuroscience" about memory de-indexing sheds some light on that: the article is about the same brain regions: CA1, CA3 and DG.

Possibly the nerdiest argument I've ever heard is claiming that #haskell programmers should stop calling <*> the "TIE fighter" and start calling it the "TIE advanced".

I love it!

I've only worked with homebuilt (rather, cobbled-together-in-the-lab-by-grad-students) CNCs, so I can't recommend specific products, but I'll try to pose some questions that you should consider, and maybe in doing so your decision will become clearer.

You say it should be metal-capable. What metals and form factors are you worried about - cutting shapes from sheet steel, milling complex 3D forms from aluminium billet, safely handling something weird like titanium or magnesium?

What size working area do you need? Is that a desktop CNC machine? A freestanding one, maybe the size of an armoire? A full commercial VMC, about the size of a minivan?

Are you comfortable maintaining it yourself, or will you need a professional to keep everything aligned/lubricated/operating? Come to that, do you want to build your own instead of buying a premade one?

Regarding 3D printers, I have a Printrbot Simple, but unfortunately I can't recommend it unless you only want to make orthogonal surfaces - diagonals and curves are terrible. You might consider something modular like the Snapmaker 2.0, which has attachments that can be swapped out to make it a CNC machine, laser cutter, or 3D printer, but of course this will involve compromises that single-purpose designs don't have to worry about.

@pixelfed Hi there! As a #blind screen reader user, I would really appreciate it if you'd take the time to #captionyourimages as it would really help with #accessibility
And it's not just people like me who appreciate them either, it's users on low bandwidth or metered connections who don't want to load the full res picture, those with #autism who sometimes find the context helpful, the huge percentage of those with preexisting visual impairments [#VI] which includes many people over 55 ETC.
It doesn't have to be anything incredibly detailed or artfully written, but something is nearly always better than nothing. I believe that their is even an option to automatically #OCR images now which should give you a head start.

this is pretty cool.
