"Mostly dead is still slightly alive"

"Re-Do Studio is a design studio founded by two friends Gaspard Tine-Beres and Tristan Kopp. They are dedicated to investigating alternative ways of production with the aim of shortening the cycle between the final consumer and the manufacturer." [more inside]

Y'all just had to get one last shot in, didn't you?

A eulogy for RadioShack. With hopes for a turnaround plan fading, RadioShack will now join other stores in opening on Thanksgiving. Jon Bois (previously) looks back on his time working for "strange, craven, five thousand-fingered strip-mall monster from a forgotten age."

The Machine

HP scaling memristor and photonic computing: "the device is essentially remembering 1s or 0s depending on which state it is in, multiplying its storage capacity. HP can build these chips with traditional semiconductor equipment and expects to be able to pack unprecedented amounts of memory—enough to store huge databases of pictures, files, and data—into a computer. In theory, that would remove the need for a conventional slow disk/fast memory system. With the Machine's main chips sitting on motherboards right next to the memristors, they can access any needed information almost instantly..." [more inside]

Pleasurable Troublemaker: Don't worry, it's totally SFW

"The wall-mounted keyholder has two hooks, one for your bike key, one for your car key. If you grab the bike key, you’re out the door and on your way. If you grab the car key, the machine drops the bike key on the floor, forcing you to stoop down and pick it up. At that point, you have both keys in your hand–effectively giving you a second chance to weigh your options.

Lead-Free Solder - friend or foe?

Lead-Free Solder - friend or foe? In 2005, the U.S. Environmental Protection Agency published a report (pdf), in which it assessed the environmental impact of tin-lead vs lead-free solder. In July 2006, RoHS legislation banned the use of lead in electronic products destined for sale throughout Europe with a few exceptions.
But not everyone thinks this was a good idea:
  • Lead-free assembly is not better for the environment, it is worse. The additional tin mining required to produce high-purity tin alloys, plus the mining of other precious metals required to alloy with tin in substitution for lead is a poor trade for the use of existing lead, much of which comes from recycled products.
  • Lead-free assembly is less reliable than lead-based assembly. The E.U. environmental commission admits this point. That's why they grant exceptions for military and high-reliability applications that still use SnPb solder.
While lead may pose a greater public health problem than SAC solder (Tin–silver–copper), the latter uses noticeably more energy to produce than lead–tin solder. Tin Whiskers have also been identified as the cause of many military, health, industrial and satellite failures.

Bigger than a breadboard II

Following on the heels of Phonebloks, a Google/Motorola formed a design group called Project Ara. The Verge recently interviewed Paul Eremenko, the project lead, about progress made towards modularization of mobile phone components, overcoming engineering issues, and the group assigning itself an ambitious timetable to succeed in delivering a sellable product within two years, or disbanding.

boom-Shack-a-lacka-lacka boom (and bust)

American electronics chain Radio Shack's dismal sales are resulting in a plan to shutter as many as 1100 of its stores. But let's look back to a happier time for the company, starting with their first catalog in 1939 and continuing through the decades: a fascinating stroll down memory lane at the Archive of Radio Shack Catalogs.

"Big waste country, the U.S."

To a Chinese Scrap-Metal Hunter, America's Trash Is Treasure: Johnson Zeng is a Chinese trader who travels across the U.S. in search of scrap metal. By his estimate, there are at least 100 others like him driving from scrap yard to scrap yard, right now, in search of what Americans won’t or can’t be bothered to recycle. His favorite product: wires, cables, and other kinds of copper. His purchases, millions of pounds of metal worth millions of dollars, will eventually be shipped to China. [more inside]

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.
