Devilishly Advocative: Microsoft Heats Ocean; Builds Skynet’s Safe Haven

February 3, 2016 by Mike Szczys 79 Comments

Have you heard that Microsoft is testing underwater data centers? On the surface (well, actually on the ocean floor) it’s not a bad idea. Project Natick seals a node of servers in a steel pipe for an undersea adventure planned for at least 10 years. The primary reason is to utilize cold ocean temperatures to keep the machines cool as they crunch through your incessant Candy Crush Saga sessions.

Passive cooling is wonderful, and really drops the energy footprint of a data center, albeit a very small one which is being tested. Scaled up, I can think of another big impact: property taxes. Does anyone know what the law says about dropping a pod in the ocean? As far as I can tell, laying undersea cabling is expensive, but once installed there are no landlords holding out their hands for a monthly extraction. Rent aside, taking up space with windowless buildings sucking huge amounts of electricity isn’t going to win hearts and minds of the neighborhood. Undersea real estate make sense there too.

But it’s fun to play Devil’s Advocate, and this one immediately raised my eyebrow. I read as much Sci Fi as time allows, and am always interested to see which authors are registering the best technology predictions. This is the second time in short order that I turn to [William Hertling’s] work. Back in November, Google announced a project to add predictive responses to Gmail. This parallels the premise of [Hertling’s] Singularity Series which begins with Avogadro Corp. Another major point in that novel is the use of offshore data centers.

High Energy Gardening Means Nuking Plants

February 3, 2016 by Bryan Cockfield 45 Comments

We live in a world transformed by our ability to manipulate the nucleus of atoms. Nuclear power plants provide abundant energy without polluting the air, yet on the other hand thousands of nuclear warheads sit in multiple countries ready to annihilate everything, even if it’s not on purpose. There are an uncountable number of other ways that humanity’s dive into nuclear chemistry has impacted the lives of people across the world, from medical imaging equipment to smoke detectors and even, surprisingly, to some of the food that we eat.

After World War 2, there was a push to find peaceful uses for atomic energy. After all, dropping two nuclear weapons on a civilian population isn’t great PR and there’s still a debate on whether or not their use was justified. Either way, however, the search was on to find other uses for atomic energy besides bombs. While most scientists turned their attention to creating a viable nuclear power station (the first of which would only come online in 1954, almost ten years after the end of World War 2), a few scientists turned their attention to something much less obvious: plants.

Russian Rocket Tech Comes In From The Cold

February 3, 2016 by Kristina Panos 80 Comments

Decades after the end of the space race, an American rocket took off from Cape Canaveral. This was a routine launch to send a communications satellite into orbit, but the situation was an historic first. The rocket in question was driven by a powerful Russian engine unlike any ever built in the States. Although this particular engine was new, the design dated back to the space age.

By the early 1960s, the Russians were leaps and bounds ahead of the United States in terms of space exploration. They had already launched Sputnik and sent Yuri Gagarin to orbit the Earth. All in all, the Russians seemed poised to send a man to the moon. Russian technology had the Americans worried enough to spy on them with satellites, and the images that came back revealed something spectacular. Out in the Kazakh desert, the Russians were building an enormous causeway and two launch pads. As it turns out, the US had every reason to be worried.

Joysix, Six Degree Of Freedom Mouse Made From Retractable Key Rings

February 2, 2016 by Gerrit Coetzee 24 Comments

[Nicolas Berger] submits his six degree of freedom mouse project. He hopes to do things like control a robot arm or fly an alien mothership.

We thought the construction was really neat; suspending a wooden ball in the middle of three retractable key rings. By moving the ball around you can control the motion of a cube displayed on the computer. We first thought this was done by encoders or potentiometers measuring the amount of string coming out of the key fobs. However, what’s actually happening is a little bit cleverer.

[Nicolas] has joined each string with its own 2 axis joystick from Adafruit. He had some issues with these at first because the potentiometers in the joysticks weren’t linear, but he replaced them with a different module and got the expected output. He takes the angle values from each string, and a Python program numerically translates the output from the mouse into something the computer likes. The code is available on his GitHub. A video of the completed mouse is after the break.

Experimental Gases, Danger, And The Rock-afire Explosion

February 2, 2016 by Adam Fabio 98 Comments

On the morning of September 26th, 2013 the city of Orlando was rocked by an explosion. Buildings shook, windows rattled, and Amtrak service on a nearby track was halted. TV stations broke in with special reports. The dispatched helicopters didn’t find fire and brimstone, but they did find a building with one wall blown out. The building was located at 47 West Jefferson Street. For most this was just another news day, but a few die-hard fans recognized the building as Creative Engineering, home to a different kind of explosion: The Rock-afire Explosion.

The Inventor and His Band of Robots

Many of us have heard of the Rock-afire Explosion, the animatronic band which graced the stage of ShowBiz pizza from 1980 through 1990. For those not in the know, the band was created by the inventor of Whac-A-Mole, [Aaron Fechter], engineer, entrepreneur and owner of Creative Engineering. When ShowBiz pizza sold to Chuck E. Cheese, the Rock-afire Explosion characters were replaced with Chuck E. and friends. Creative Engineering lost its biggest customer. Once over 300 employees, the company was again reduced to just [Aaron]. He owned the building which housed the company, a 38,000 square foot shop and warehouse. Rather than sell the shop and remaining hardware, [Aaron] kept working there alone. Most of the building remained as it had in the 1980’s. Tools placed down by artisans on their last day of work remained, slowly gathering dust.

Build Your Swarm: Control Cockroaches For Under $30!

February 1, 2016 by James Hobson 40 Comments

Have you ever wanted to control an army of cockroaches? We’ve all seen remote control cockroaches before — and they really are quite a fascinating specimen to work with — but did you know you can control one for about $30 worth of components, with a Arduino Micro?

It’s actually pretty simple. By stimulating a cockroaches antenna with variable frequencies (to mimic neural signals) you can convince the cockroach that they’ve hit a wall and should turn the other way. What results is a remote-controlled roach. How cool is that!

FTDI Drivers Break Fake Chips, Again

February 1, 2016 by Brian Benchoff 322 Comments

Just over a year ago, FTDI, manufacturers of the most popular USB to serial conversion chip on the market, released an update to their drivers that bricked FTDI clones. Copies of FTDI chips abound in the world of cheap consumer electronics, and if you’ve bought an Arduino for $3 from a random online seller from China, you probably have one of these fake chips somewhere in your personal stash of electronics.

After a year, we have the latest update to FTDI gate. Instead of bricking fake chips, the latest FTDI drivers will inject garbage data into a circuit. Connecting a fake FTDI serial chip to a computer running the latest Windows driver will output “NON GENUINE DEVICE FOUND!”, an undocumented functionality that may break some products.

FTDI gate mk. 1 merely bricked fake and clone chips, rendering them inoperable. Because fakes and clones of these chips are extremely common in the supply chain, and because it’s very difficult to both tell them apart and ensure you’re getting genuine chips, this driver update had the possibility to break any device using one of these chips. Cooler heads eventually prevailed, FTDI backed down from their ‘intentional bricking’ stance, and Microsoft removed the driver responsible with a Windows update. Still, the potential for medical and industrial devices to fail because of a random driver update was very real.

The newest functionality to the FTDI driver released through a Windows update merely injects unwanted but predictable data into the serial stream. Having a device spit out “NON GENUINE DEVICE FOUND!” won’t necessarily break a device, but it is an undocumented feature that could cause some devices to behave oddly. Because no one really knows if they have genuine FTDI chips or not – this undocumented feature could cause problems in everything from industrial equipment to medical devices, and of course in Arduinos whose only purpose is to blink a LED.

Right now, the only option to avoid this undocumented feature is to either use Linux or turn off Windows Update. Since the latter isn’t really a great idea, be prepared constantly roll back the FTDI driver to a known good version.
