Code

code and software projects

pretty much everything i do has been electronic or had electronics and code buried within it forever, but not much of it has made it to the intertubes. it should be no surprise that most of this is now code, and electronics to support that code. (since the world remains firmly analog there remains analog electronics, mostly as interface to code.) everything i do is embedded, no graphics, no commod...

Processing and Arduino

WORK IN PROGRESS The code and projects on this page are suitable for novices, but assumes you have mastered the basics of loading programs into the Arduino (eg. the BLINK program, at least) and can run demo programs in Processing. Goal The code and program examples here will provide you with a way to extract event information from a very simple analog sensor. By itself, the sensor/resistor pair...

Project PIC source code

These are sources to various WPS projects (and umm products). Most are PIC sources, for an old PBASIC compiler. Most of them are Story Teller components, and further non-technical information can be found in those pages. The rest of my projects don't contain PICs....

super I/O gargle blaster!

23 feb 2015 a common application for a microcontroller is to provide an electrical interface to the world outside a desktop/laptop computer. a nice idea in theory, but in practice, like a lot of things, the devil is in the details: how to think about and process what a sensor (or switch, or other outside-the-computer physical thing) is doing, and what data from it means. and then import that info...

Review of Andrew Hodges' book, Alan Turing: the Enigma

by Tom Jennings <tomj at wps dot com>, April 1999 Please refer to the Alan Turing homepage, and to my Story Teller. One of the few books on my 'keep forever' list Without this book, the real Alan Turing might fade into obscurity or at least the easy caricature of an eccentric British mathematician. And to the relief of many, because Turing was a difficult person: an unapologetic homosexual...





Computation

Book review: A Million Random Digits with 100,000 Normal Deviates

the RAND Corporation, 1955 Free Press Publishers, Glencoe Illinois This is a strange book, possibly the oddest book I own, and I have a few oddballs on my shelves. On it's face, it's a rigorous mathematical table, the intended audience those working in specialized mathematical fields, so it's strangeness is not that obvious. First, a bit of background... However useful mathematical table...

The Universal Machine

meh. i did this paper design during the year i was working in san francisco, while josh was in law school. i didn't have any way to work on anything physical so i did this paper design. it will never get built of course. feb 2012 My most recent (and most complicated) project is this Universal Machine. I keep repeating this paragraph from the Logical Design manual (below) as I've not yet said it b...

idiosyncratic human skills are the opposite of capitalist culture

i think a 3 year old could answer many of these, and formulated appropriately, most mammals could work with these ideas. dogs certainly can. language is not intelligence, and intelligence is not language. questions to ask ai keeping questions within realms of things that, though they exist in the physical world, are relations that can be described textually/logically. this isn't fair really sin...

The standard for RS232 sets these signals on the various pins.

I swiped this source from http://unix1.hials.no/~aoy/home_uk.html, it was so damn useful I was afraid it might disappear. Finding this document was one of the things that made me consider that the web might actually be useful. It saved me the trouble of walking across the street to my office to pull out a paper copy from the back of some hideous manual. The ambivalence I have towards this event ex...

Paper tape

Paper tape is a data storage medium from a past century. It's roots are in mid-19th-century telegraphy. The cliche "dit dit dah dah" sound of audible telegraphy is really that of simple point-to-point radio Morse Code telegraphy, such as amateur radio or, once upon a time, ships at sea. Telegraphs, as in telegrams, business and personal messages and all that, started out as visible marks on lon...





Documentation

book library

updated 10 july 2017 work in progress. this is the catalog for mybook library. it's mostly but not quite exclusively focused on computation (not only computers), electronics (from physics to so-called digital), physics especially radiation physics, science and history and historiography of science, numbers and symbols, algorithm and code and mechanism. most of it original (commercial) materials f...

Various datasheets and catalogs

The following are catalogs that will not be scanned. They're too specialized or difficult. The only one of general interest is TI Integrated Circuits Catalog, but it's hard-bound with tiny margins and many, many pages. Indexing it all terrifies me. NOTES: "no ZIP" in the date column means there is no date, but the address has no ZIP code, which came into use around 1963. When the pub date is "195...





Pedagogy

Managing technical complexity in art making

Art involving technology, especially constantly changing media technologies, or multi- or cross-disciplinary work, is a peculiar thing. Practitioners of specialized fields, such as more-traditional video, audio, robotics, often work towards a degree of mastery in a field by persisting at it over time; they gain depth that lends "authority" to them and their knowledge. Alas, art technology practit...

ping stick

the ping stick demonstrates some ideas implicit in embodied cognition, the philosophical idea that, in essence, what we call 'mind' is deeply and irretrievably embedded in, a part of, the body. it's a really interesting subject and a useful way to think about thinking and the body and interface (computer or otherwise) . the wikipedia page on embodied cognition is a decent introduction. the p...

Sensing, Perception, Physics

"...And not everyone has gone through that thought process." Indeed. "The systematic, careful collection of measurements or counts of relevant quantities is often the critical difference between pseudo-sciences, such as alchemy, and science, such as chemistry or biology."

Bits, Bauds, & Modulation rates

Serial communications, here meaning RS-232 and current loop 1999, revised slightly February 2005 mark and space -------------- Serial lines are either spacing, or marking. I was always confused as to what mark or space meant, which was the state of the line when no characters were being sent, etc. I can't understand why now, it's amazingly simple. The resting state is called "spacing". Mark...

References and materials

Tom Jennings You might take a look at my "What is World Power Systems" rant, here. It carries the flavor of the approach I take to technology. Here are some of my references for the class of 22 Jan 2003.I'll eventually post my outline here; this is more or less a set of sources I've come across in my work. They're not in any order; some of the original materials will be utterly alien to you, ...

Number and character representation within computers

How is a number (quantity) represented, stored in memory, or sent via some communications protocol? There is no "real" or "right" way. When you have the concept in your head of "one hundred and twenty three", how you express that is utterly independent from the concept. Arabic or roman digits, 123 small stones, etc. The concept of a quantity is utterly independent of it's representation. The ser...

San Francisco queer punk

the black flag of anarchism

by Paul Goodman OK a little starry-eyed but close enough as an over-simplified underpinning of the anarchism that I know that I still refer to it. -- tomj Anarchism is grounded in a rather definite proposition: that valuable behavior occurs only by the free and direct response of individuals or voluntary groups to the conditions presented by the historical environment. It claims that in most h...

Greta Snider's PUNK ROCK DATING GAME

This is a program written in Director for the Macintosh, which means it's quite large, some 8.8 megabytes to download. It's definitely worth it though, especially if you live in San Francisco. It's almost too revealing... it's really great, and I HATE computer games of all sorts. I've even left it running just to hear the music in the main page. Download here: punkdate.sit (8.8 MB). Unstuffing i...

"texts" archive, from worldpowersystems.com's gopher server

Pictures of 2350-2360 Allesandro

April 2011: out of place but no place to put it: some fool drives into the front of our house. Josh & I bought this property in February 2001. Where others see disaster we see promise. It will be our house and my workspace and possibly an income property (it's really two adjacent lots). (Missing is a plot map which shows orientation, unfortunately, this text assumes you can see the invisibl...

2001 Venice Bienalle

Some photos from my trip to the 2001 Venice Bienalle. My Model 71 was part of the Temporary Autonomous Pavillion, hosted by the Slovenian Pavillion, curated by Vuk Cosic. There's not much to these photos, it was a very hectic week and I only took a few photos. This is all I've got....

21 October, 2002 Once upon a time. This is my boyfriend Josh. We've been together for just over ten years (as of October 2002). He's a lawyer, but don't hold it against him -- he works for Neighborhood Legal Services, doing community economic development work here in Los Angeles that in a sensible country at least some of which would be done by government, and often just undoing damage that loca...

Using Photomultipliers in Two-Wire Probe Configurations

The following diagram depicts how a PMT operates in the two-wire probe configuration. The probe wire must supply dynode resistor string voltage while simultaneously providing signal pickoff for counting. While we show the dynodes as "grids" they are more like "cathodes" in a triode. They *will* source current pulses into the dynode resistor string. For this reason the upper dynodes must be bypas...

Video work

"Essex Army Airfield doco" Operation ARGUS was a fairly insane, dangerous and messy series of high-altitude nuclear experiments with the intent of testing theories of communication disruption caused by ... high altitude nuclear explosions. Classic Cold War insanity. The cavalier, cowboy nature of the shaky technology is evident if you watch the film carefully; with live nuclear devices attached,...

The Black Hole of Los Alamos

Ed Grothus' Black Hole, aka Los Alamos Sales Co. nominally sells what he calls "nuclear waste" -- surplus from the infamous Los Alamos National Laboratory, home of the Manhattan Project in the 40's, and of even less-reputable horrors in the decades that followed. Embedded in the rigidly tranquilized town of Los Alamos like an infected thorn, Ed the Red pisses of the townies merely by existing and ...

Trouble is a microscopic Chinese Crested Dog, mostly hairless, fine baby-girl blonde hair, fair skin with freckles. He was the runt of the litter, most were 8 lbs, he is 5.5lbs. He was not housebroken when I got him (it took over six months...) as he spent the first 18 months of his life in a kennel run, in excellent health but little if any socialization, dog or human. He loves riding in the car ...

Josh & Tom's dogs

(This page is new (April 2002) and existing scattered dog pix and such will get moved here. As always, it could take years (really).) Josh & I have two dogs: Molly, a Peruvian Hairless Dog, and most recently, Dart, a Xoloitzquintli ("xolo"). Molly was born around 1 January 1996 and Dart on 1 February 2002. As I write this Dart is just a baby, and doesn't even know his name yet. Molly has a hu...

magnetic tape for data storage

once universal, now forgotten, storing digital data (not analog sound) on magnetic tape is pretty much a lost art. i like magtape for its physicality. a small reel of half-inch tape typically holds 10 megabytes, for an approximate sense of working with it. the specifics of linear magnetic data recording have very little presence on the world wide web for a number of reasons; while disk drives are ...

This is a gratuitous picture of me at 2, sticking my little hand into the hub of my father's Ford Model A's spare tire. This is in 19 fucking 57, can you believe it, I talked to my father just today, and he asked how old I was -- 38. Holy shit! You can't be 38! (He's 62.) But anyways. In there is where the bearing races fit, and it's normally packed with thick snotty stringy grease. I think I reme...

THE TOILET CAMERA WAS A HOAX -- FUCK YOU ALL!!! HA HA HA HA!!

In 1994 I put up this fake toilet camera web page, to poke fun at the idiotic cameras-on-coffee-pots and other net.nonsense that was all the rage then -- but it backfired. Many people took it seriously, and even TIME magazine gave it an anonymous mention in an article about the horrors of the internet (an age-old tradition in mealy-mouthed media -- any change in the culture is doomed to 'signal...

South West U.S. Travelogue (2002)

This is a personal account of portions of my road trips around the SouthWest U.S. I'm not much for taking pictures on trips, I just never quite get around to it (if I even bring an operating camera). I generally skip the obvious tourista places, let's be real, they're done to death, unless I can squeeze some amusement from them. And there are some places I won't document, because they shouldn'...
