Skip to page 12 for some real fun. Philbrick must have owned stock in a battery factory.

In 1937-38, computer pioneer George Philbrick worked for the Foxboro Co. as an analyst. He had the radical idea of building an electronic analog computer to simulate the behaviour of hydraulic industrial equipment, so Foxboro customers could experiment with control systems without needing a pipe wrench. One of the world's first analog computers was ignominiously ferried around the U.S. in the back seat of Philbrick's car. Ironically, Philbrick didn't give his "Automatic Process Analyzer" a properly techy, pretentious nickname. He dubbed his one-eyed monster Polyphemus. (PDF) (prev)

Don't bother looking at Wikipedia for an article about George Philbrick.

It has always been difficult to look up any information on the pioneers of computing. Even today, in the Internet age, one has trouble finding much about early computers--even on the ultimate computer network.

Consider the late George A. Philbrick. He was one of the titanic figures in electronic computing in the 1950s--mainly because of the company he founded, which was a major manufacturer (and pioneer) of the operational amplifier, at a time when an "op-amp" was made of vacuum tubes. Op-amps were used to build analog computers, which were widely used to simulate physical processes in the days when digital computers were either non-existent, or too slow and costly, for many kinds of simulation and process-control work. Op-amps, in chip form, are still widely used in electronics. Yet, despite his unquestioned status as a major pioneer of electronics, there was almost nothing on the Internet about Philbrick or his company.

Until 2005--when Joe Sousa decided to put up a website dedicated to Philbrick's legacy. Behold The Philbrick Archive.

What is the relationship between the optical groove in a record or wax cylinder and sound, and how can we use this to recover analog recordings from the past? Dr. Carl Haber explains IRENE (.pdf; begin at slide 44 for audio samples).

Ben Laposky, the Father of Computer Art?

Chinese Jet Pilot — Tue, 23 Jan 2007 16:49:51 -0800

Pioneering electronic artist Ben Laposky began creating his “Oscillons” – abstract artworks created by photographing Lissajous figures off a cathode-ray oscilloscope – in the early 1950’s. Some consider him the father of computer art, and the beauty and clarity of his work is astonishing.

Scifi magazine covers, 1930-today

A year-by-year archive, from 1930 to the present, of every poignant, creepy, tacky, tragic, goofy, beautiful and, yes, kinda slutty cover of the magazine that started out as Astounding Stories of Super Science and became Analog, with lots of changes in between. [via the horse's neck]

The World's Cutest Synth!

Rev. Syung Myung Me — Sat, 08 Jul 2006 11:40:16 -0800

Have you ever seen a synth and said "Man, what this needs is cartoon eyes?" A bit similar to the Buchla Box or theremin in that they don't have a keyboard to control the sounds -- it's probably closest to the Booper, invented by The Weatherman from Negativland (or, well, Circuit Bending), the Thingamagoop is a photosynthesizer... which means it basically uses light sensors to generate sounds. The signal's run through a couple oscillators and, well, it comes out as somethin' that's pretty dang awesome. I'm on the fence on pickin' this one up. On one hand, it's a really neat toy that makes noise... on the other hand, um.... um.... I dunno. It's not made of candy?

But is it MUSIC?

David Webber makes awesome sound art things from christmas trees, pot plants, household stuff, food blenders and hard drives. His good friend Ray Wilson builds awesome modular synths. Ray will also show you how to make your own Weird Sound Generator.

Another Synth Guru Has Left Our Presence

John "Paia" Simonton died late last week. His company, PAiA is one of the grandfathers of the DIY synth scene. I have one of his modular synths half-constructed in my garage. He helped create an American buzz for electronic music and DIY music gear in the 70s, and was highly influential till his passing away.

Analog tape crisis

Quantegy, the last remaining branded manufacturer of professional audio tape, closed its doors and filed for Chapter 11. But it seems there's hope that they'll bounce back.

How to convert LPs to CDs. Many audiophiles will mock the software they suggest using as well as the hardware pictured, but this is aimed for the everyday people that don't have a laser turntable or ProTools. All in all, a decent introductory guide.

The nukes are alright... "since most American nuclear plants were built in the 1960s and '70s, they operate on analog systems, and are unlikely to be affected by digital errors." I feel so much safer now...
