Apparently making a flying car is not that tough.

Chip fabrication in the garage August 24, 2021

Chips ahoy!

This fellow has succeeded in making a chip prototype in a home setup…not your ordinary garage, it’s true; he’s got equipment I bet you haven’t got. Still, none of it is truly impossible to get if you want to spend a little money.

No title, just watch and see August 20, 2021

I really enjoy deadpan delivery and self-deprecating humor and therefore watch Integza on Youtube…but this guy has help with deadpan from his hilariously barely-patient pregnant wife, whose archery skills are really, really good…compared to his especially. Naturally, his competitive nature will not tolerate that…

Be careful with that thing. You’ll put your eye out.

Human Biology and the Iron Man Suit April 16, 2021

Robert Sapolsky is a genius lecturer and neuroendocrinolgist at Stanford whose lectures are part of Stanford’s video lessons. Check him out here (maybe start with Lecture 24, like I did, and then start again from Lecture 1. Trust me).

Alex Burkan is “some mad Russian guy” who is building an Iron Man suit in in a cave from a box of scraps his machine shop with oddly compelling first choices for prototyping muscles (from electrolyzed water for high-pressure hydrogen) for the exoskeleton, using high-pressure hydrogen for a repulser (nearly blowing off his arm) and launching missiles…also, he’s hilarious.

Finally, my handwriting sucks so I thought I would practice journalling to work on it. Then I thought about stuffilike.net and how I never post anymore (see “Bad Things” earlier in time) and it occurred to me that I could kill two birds with one virus, er, stone. So, here’s a first go at making my journalling/handwriting practice relevant to stuffilike.net.

OCR results will vary. All the free ones (not counting Evernote, because I haven’t tried it yet) yield crap:

Onlineocr.com version:

This does not surprise me.

Google Docs version:

It is possible I could use this method (take picture or scan to .pdf, then “open in Google Docs”) if my handwriting improves. We shall see.

Well, I did say my handwriting was pretty poor. And it was attempting to read cursive, a style which I understand is no longer taught in USA schools (you poor kids. Are you going to be able to neatly print in time to write enough to pass essay exams?).

Ion-propelled Aircraft December 8, 2020

Yanked from the scripts of Star Trek with embarrassing plagiarism, researchers from MIT have created a proof of concept aircraft propelled by ionic thrust. They have only tested it in a (pretty large) gymnasium, but it’s impressive nonetheless.

Simple in concept[0], a wire with 20Kv ionizes air in front of an airfoil while the oppositely-charged airfoil draws the air over itself:

The amount of thrust generated by this system is pretty small admittedly, so there are several airfoils stacked atop one another to provide enough lift for sustainable flight.

…well, it is just a prototype

An intriguing design, it is possibly a first step of a solution to the problem of noisy propeller-driven flight. If we imagine a future with drones filling our skies, I sure hope they are quiet[1]

For all aspiring script kiddies security researchers: the demo site for web vulnerabilities from OWASP, OWASP_Broken_Web_Apps_VM_1.2, is available on SourceForge. Set it up as a virtual machine using VMWare or VirtualBox (if your mom’s purse doesn’t have a few hundred bucks in it company doesn’t have a budget for VMWare), run it as a website inside your box, then set up Kali Linux as another virtual machine and attack it.

Fun for all.

I texted this picture to my stepdaughter. She wrote back:

“Did it work???”

“Can’t tell; everything is still weird.”

NOTE: it’s funny how you can remember something as strange as “chrono-synclastic infundibulum” and spell it off the top of your head after having read it once in high school, nearly fifty years ago.

Capable Modular Robots November 9, 2019

 MIT’s Computer Science and Artificial Laboratory’s M-Block robots can self-assemble into different structures. The little cubes (in development over the last six years) have gained the ability to jump, flip, spin, and recognize each other. A barcode-like system on each face of each cube, allowing them to identify the other cubes around them.

The engineers wanted to see if the M-Blocks could (for example) form a straight line or form a random structure using the new communication algorithms. They waited to see if the blocks could determine how they were connected, and then what direction they would need to move to create that line. They found that 90% of the block swarm knew which motion and guidance to move to accomplish the task. I’m curious to know what the other 10% did…

Engineers hope to create a more substantial swarm of blocks (>16) that can assemble to form more complex structures with new capabilities.

It’s lovely what you can do with 3D printers. It is, of course, best illustrated by a cackling madman with a Gatling Gun.

 

EXCITING UPDATE: I tend to forget the excellent work done in a related space by Jeorg Sprave, a happy German fellow who specializes in rubber-driven devices for impelling various projectiles:

As the video shows, he is also a giggling maniac, just this time with an electric fully-automatic crossbow.

Frankenprinters May 14, 2019

My army of loyal readers (hi, Mom!) will recall my fondness for and fascination with the promise of 3D printers, and similar robotic manufacturing techniques. I should have acquired several by now, but I am famously cheap thrifty and so never indulged this particular whim..until just a bit ago when I acquired three not-working printers from a cosplay parts dealer named Alder (last name redacted, because I never learned it) for a bargain price of a hundred bucks apiece.

image

They each had at least one major thing wrong, and all had some disconnected wiring. The middle one had a missing limit switch on the y-axis and a missing adjustment for the z-axis (it’s still missing; I am going to try and fix that this evening–look for exciting updates) limit switch.  I can’t tell what else is wrong with it until I stop threatening my build plate.

The left one needed a bit of wiring (fairly easy to find wiring diagrams for the boards attached, with a bit of intuition) and an adjustment to the z-axis limit switch and a new motherboard. The right one needed (may still need) a new heated build plate (I am currently using it as a PLA printer, so a hot plate is not so critical), wiring, z-axis adjustment and some patience, as I was a little too stupid to fix it myself when I bought these guys a while back.  I had to grow in confidence before I could troubleshoot. In fairness, the exhausting regimen of commuting between my work and home on weekends (six hours one way) really dampened my spirits.  I’m not usually such a coward.

I forget how many of them needed new hot ends or thermistors (two, I think) and rewiring to accomodate them.

Lastly, all needed new blue tape (very important; no adhesion without fresh tape!)

and one needed new glass.  The first print (with new tape) did not photograph well:

I attribute poor image quality to beer; cameras should never drink.

 

3D Models Through Multiple Primitives January 7, 2019

Sometime the 3D scanner can’t model complex interiors. Geeks to the rescue:
The authors of a nifty paper describe how their software creates solid models based on a kind of successive approximation using a library of primitive shapes.  They claim success in over one hundred complex models (see video, above).
