CES 2013

The International Consumer Electronics Show has been hosted in some form or fashion since 1967. But with the absence of Amazon, Apple, Google, and Microsoft, journalists are asking if the show is still relevant.

DJ Focus

DJ Focus couldn't wait to get back to Sierra Leone. AKA Kelvin Doe, this young man makes beautiful, functional and very useful electronic devices out of trash found in his native Sierra Leone. It's not clear whether he or M.I.T. was more impressed after his visit there.

Three Ts and Gold

The 555 Timer IC

The simple but powerful 555 timer IC can be rigged to produce a timed pulse or a square-waveform oscillation up to 68kHz. It later came in dual-timer (556), quad-timer (558), military-grade (SE555), and low-power (7555) configurations. Although it's largely obsolete in commercial electronics, it became beloved of amateurs wanting an easy and cheap way to make things buzz or blink. In memory of the recent passing of its inventor, Hans Camenzind, Make Magazine offers a retrospective of 555 contest winners. Here's a tutorial on chip function from instructables. How to build a toy piano. The morse code practice circuit. Miniature beeping circuit prank to baffle your friends and co-workers and a screaming altoids tin.

The art of the teardown

There are more than a few websites that take electronic products and document their disassembly. What makes Mike Harrison's YouTube videos stand out is that while doing a teardown he attempts to identify the components and subsystems of a product and explain why a product was made the way it was made. From something as simple as a CD stereo system to a Jumbotron panel. Mike's website has been discussed previously. [more inside]

Just one planet like it

Electronics companies all over the world are increasingly reliant on certain rare metals, most of which are mined in China, which controls 97 per cent of the global supply. The Chinese government has promised to slash export quotas to ensure future sustainability of the world's supply of rare metals. China will drop its quota by 35 per cent in the first half of this year as compared with the same time last year. But despite its escalating consumption of rare metals and the need for future sustainability, the West's electronics industry is mistrustful of China's motives and claims that the move has more to do with the mainland's desire to dominate electronics manufacturing than ensuring the future sustainability of the world's supply of rare metals. ~ Greening conscience or resource checkmate? The rare earth trilogy covers eWaste harvesting, restarting interest in mines and dithering around trade regulations, all in one neat package. [more inside]

I think the primary reason was Steve Jobs' hatred of screws

Kyle Wiens of iFixit talks to ArsTechnica about iFixit's history ("my iBook G3...It seemed crazy that I couldn't find any information online on how to get the thing back together"), his goals ("we realized that the world needed free, open source service manuals, and the manufacturers weren't stepping up"), planned obsolescence, the dirty tricks manufacturers pull to make it harder to repair your own stuff ("Torx has a patent...They're using lawyers to prevent people from making their computers last longer than 3-400 battery cycles"), who are the design kings of repair and servicing, who the villains are, and why recycling electronics isn't all you'd probably like it to be.

EricArcher.net

Eric Archer has created some really great electronic devices, using primarily 1970's technology. His audio work includes a sort of retro synth studio in a box, a generative sequencer based on LFSRs (more commonly used in cryptography), and and several infrared synced devices like this analog drum machine. He's also made an analog computer and oscillography art generators.

All we hear is radio ga ga.

Audiophoolery: Pseudoscience in Consumer Audio. You might think that a science-based field like audio engineering would be immune to the kind of magical thinking we see in other fields. Unfortunately, you would be wrong [...] As a consumerist, it galls me to see people pay thousands of dollars for fancy-looking wire that’s no better than the heavy lamp cord they can buy at any hardware store. Or magic isolation pads and little discs made from exotic hardwood that purport to “improve clarity and reduce listening fatigue,” among other surprising claims. The number of scams based on ignorance of basic audio science grows every day. Via.

The machines are making such a wonderful music, who would want to pull the plug?

Computer music is relatively old, going back to the very early 1950s. In the following decades, people have been creative with programmable technology, leading to "She'll Be Comin' 'Round the Mountain" being played on an IBM chain printer back in 1966, and in more recent years, HP ScanJet 5100c included an Easter Egg. The HP ScanJet 4c's SCL (Scanner Control Language) unofficial PLAY TUNE command lead to these fine little ditties. Now over a decade ago, the duo known as [The User] enlisted three specialists to operate a computer program via a server that synchronized the dot-matrix printers and read complex ASCII text files in order to create musical compositions. The result was a techno-sounding piece that was performed by the administrators of the system, rather than one that was simply being played. Like a symphony of car horns, the coordination of these printers became Symphony #1 and #2 for Dot Matrix Printers (samples of Symphony #2, Symphony #2 Slashdot thread).

Paper. Rock. Scissors.

In 1986, most gamers who were lucky enough to own a new video game system at home were playing the original Nintendo. It's launch in 1985, a year before the Sega Master System was launched in the states, allowed it plenty of time become the most popular console in the market, and the game Super Mario Bros. quickly became the best-selling video game of all time (a title it continues to hold, having sold over 40 million copies to date). However, even though Nintendo commanded 95% of the North American video game market at the time and the CEO of Sega made little effort to promote and market it, some people still bought and gave the Sega Master System a chance. Perhaps it was the 3-D glasses or it's unique ability to read multiple media inputs... or perhaps that the original version of the system had a secret game built right into it (and it was unbeatable!).

Deep Geek: Understanding Memristors

The coming memristor revolution in electronics and how it works. The newly created memristor, only the fourth fundamental fundamental type of passive circuit element, has the promise of computing advances both prosaic (faster, cheaper and "bigger" flash drives) and momentous (relatively effortless mimicry of brain cells and their activity). This is the story of the memristor's genesis, told by R. Stanley Williams, the leader of the team that created the device. [more inside]
