Reconstructing the Antikythera Mechanism

 

"Clickspring" makes gorgeous videos about an inspiring project: building a replica of the Antikythera mechanism using only period-appropriate tools and methods.

 
I particularly like this project because it's an excellent way to debunk the "ancient astronaut" kookery surrounding this piece of ancient technology (and other "too advanced" ancient human achievements).

Cory Doctorow on John Deere's Tractor Killswitch

https://doctorow.medium.com/about-those-kill-switched-ukrainian-tractors-bc93f471b9c8

 

Most of us have heard about the Russian looters who stole a bunch of John Deere equipment from a Ukrainian dealer and hauled it to Chechnya, only to be foiled when the dealer remotely disabled all those implements. Heartwarming! But . . . This essay ties together several issues in a very neat, very disturbing bundle. The big surprise for me was

Random Friday Links: FAO Blacksmithing Manual

 An FAO publication: Agricultural Engineering in Development: Basic Blacksmithing: A Training Manual. Might be worth getting a hard copy of this one.

 Only a few this week.


A nuts & bolts look at the world of writing for money:

Some good-looking radios from a brand I hadn't seen before. I have one on order, I'll let you know:

Nestflix: a directory of movies-within-movies (and tv shows). Yes, they have Logjammin'. Yes, they have McBain. But you can submit any they don't have.

The photographs of Zaharia Cusnir. A village photographer in the Romanian/Moldovan border region from 1955-1970, Cusnir lived and died in relative obscurity. His negatives were found in an abandoned house, scanned, and now some are on this website. Some of the images are quite powerful: your heart goes out to the subjects. I will be spending more time with these over the weekend.

Shaving Horse in Action: Hungary 1940

I found this on Fortepan. A man cuts stovewood (or something like it) with a bent-wood bowsaw, using a shaving horse to hold the wood still, or so he can cut wood while sitting down:

Hungarian Photo Archive

Thanks to Hyperallergic (an arts e-newsletter), I have discovered Fortepan. Fortepan is a treasure trove of photos taken in Hungary (or by Hungarians) in the 20th century. 



---minnow traps, 1941


The photos can simply be looked at in simple chronological order, or searched by subject. Use Google Translate to find the Hungarian word for your subject. Usually this results in awkward half-fitting results, but you can go from there. I found the above image by searching for "halasz," which Google Translate tells me is Hungarian for "fisherman."

Rib Lake Sounds




The link below is to a folder on my Google Drive called "Rib Lake Sounds."



The files in the folder are all .wav files. If you can't play them on the folder, you'll have to download them. Maybe I need to use Soundcloud or a similar audio file hosting service.

For a long time I've wanted to make my own recordings of nature sounds in places I love. This past winter, I bought a digital recorder for working on videos for Highland Woodworking. I usually use this recorder with an external microphone, for voiceovers. But it also has a pair of built-in mics that do pretty well, so I decided to give it a try, even though when I looked at various sites devoted to recording nature sounds, I was led to believe the result would be of low quality.

During a May trip to my place in Wisconsin, I set up the recorder on a tripod, started it recording, and walked away for an hour or so. I had to experiment a bit with the recording level, and once I came home I snipped off the bits where you can hear me walk away at the beginning, and then walk back up to the recorder at the end. You might hear a car in the distance. You might hear an airplane, or a dog. To be honest, they bother me far less than I expected.

Track Notes
"Marsh Morning of May 4th" is a typo, it was recorded May 14th. I left the recorder near the edge of a pond full of cattails, mostly hoping for blackbird song. I got that and more. This track is the only one in which wind noise is an issue - - even though the mic was covered with a wind sock. So picture a sunny, breezy morning overlooking a pond.

"May 15 Dawn" is my favorite so far. How many species of birds can you count? How many can you identify? I'll start you off with ovenbirds and veerys. Perhaps you'll need good earphones, or speakers with good bass to catch it, but there's a ruffed grouse drumming most of the way through. There is also the sound of occasional drops of water falling off the trees and onto my deck; the night before it had rained. I rolled out of bed at 5 am and set up the recorder on the deck to make this one, so imagine the light slowly rising as you listen.

"Frogs at Pond" is was taken just after sunset on May 14th. Sorry for the volume! They were quite loud. In fact, they hurt my ears. As I set up to record, when I put on the headphones and listened through the microphones, I was able to reduce the levels so they weren't painful. Wood frogs, spring peepers, chorus frogs - - - and is that the elusive mink frog?

"Afternoon Breeze in Pines" is the recording I wanted to make when I first thought of this project. There is a high spot on my land where most of the trees are red pines about 50 years old. I love to sling a hammock between two of them and listen to the wind in the pine needles. Probably the first sound in nature that made an impression on me, certainly before Kindergarten. I think I captured it, though you can also hear running water down below; spring runoff was near its peak when I visited.

A general note on "why": Anyone who knows me well won't be surprised to hear I spend lots of time daydreaming about being in the woods of northern Wisconsin. This has motivated a lot of photography and a few videos over the years. But at work, and in the car, I can't be gazing lovingly at photos. On the other hand, I can have the sounds of home in the background. And, obviously, sound recordings tap into a whole other emotional dimension.



ps) there are several "unreleased" tracks in the vault, including one recording made where two small streams meet. That one is of very high quality, but when it plays I have to pee every 7 minutes. The world isn't ready for it.

Set Your Car to Nookie Mode

Worth reading. Based on the concept: what if human nature remains about the same as "driverless cars" become commonplace?
