Once upon a time, countries protected their domestic industries with tariffs on imports. This gave the home side a price advantage over companies operating overseas, but the practice has somewhat fallen out of fashion in the past few decades.
These days, governments are altogether more creative, using fancy export controls to protect their interests. To that end, the United States enacted an export restriction on high-powered computing devices. In response, Chinese designers are attempting to artificially slow their hardware to dodge these rules.

Researchers from MIT and Stanford are taking the ‘person’ in ‘personal assistant’ to mean something more literal with these robots that scurry around on the user’s clothing.
Project Kino — inspired by living jewelry — are robotic accessories that use magnetic gripping wheels on both sides of the clothing to move about. For now they fill a mostly aesthetic function, creating kinetic accents to one’s attire, but one day they might be able to provide more interactive functionality. They could act as a phone’s mic, adjust clothing to suit the weather, function as high-visibility wear for cyclists or joggers, as haptic feedback sensors for all manner of applications (haptic sonar bodysuit, anyone?), assemble into large displays, and even function as a third — or more! — hand are just the tip of the iceberg for these ‘bots.

Hackaday readers are a vast and varied bunch. Some of us would call ourselves engineers or are otherwise employed in some kind of technical role. Others may still be studying to gain the requisite qualifications and are perhaps wondering just how to complete that final leap into the realm of gainful employment. Well, this one’s for you.
What sort of job are you looking for?
You might be a straight, down the lines, petroleum engineering graduate who’s looking to land a job in the oil and gas industry. Conversely, you might be an arts student who’s picked up a few skills with electronics over the years and are keen to gain a position doing grand installation pieces for musuems or corporate clients.
There’s a broad spectrum of jobs out there that require high-level technical skills, and my first piece of advice is that you shouldn’t limit yourself. There are things you can do to keep your options open, even over a long career – these could pay dividends when you’re looking for a seachange.

We’d never seen an iconoscope before. And that’s reason enough to watch the quirky Japanese, first-person video of a retired broadcast engineer’s loving restoration. (Embedded below.)
Quick iconoscope primer. It was the first video camera tube, invented in the mid-20s, and used from the mid-30s to mid-40s. It worked by charging up a plate with an array of photo-sensitive capacitors, taking an exposure by allowing the capacitors to discharge according to the light hitting them, and then reading out the values with another electron scanning beam.
The video chronicles [Ozaki Yoshio]’s epic rebuild in what looks like the most amazingly well-equipped basement lab we’ve ever seen. As mentioned above, it’s quirky: the iconoscope tube itself is doing the narrating, and “my father” is [Ozaki-san], and “my brother” is another tube — that [Ozaki] found wrapped up in paper in a hibachi grill! But you don’t even have to speak Japanese to enjoy the frame build and calibration of what is probably the only working iconoscope camera in existence. You’re literally watching an old master at work, and it shows.

It’s been said that hackers are enamored with complex networks. In the 60s and 70s, the telephone network was the biggest around, singing a siren song to an entire generation of blue-boxing phone phreaks. I started a bit closer to the house. As a child I was fascinated by the heating system in the basement of our home: a network of pipes with a giant boiler in the middle. It knew when to come on to provide heat, and when to kick on for hot water. I spent hours charting the piping and electrical inputs and outputs, trying to understand how everything worked. My parents still tell stories of how I would ask to inspect the neighbors heating systems. I even pestered the maintenance staff at my nursery school until they finally took me down to see the monstrous steam boiler which kept the building warm.
My family was sure I would grow up to be a Heating Ventilation and Air Conditioning (HVAC) tech. As it turned out, electronics and embedded systems were my calling. They may not have been too far from the truth though, as these days I find myself designing systems for a major manufacturer of boiler controls and thermostats.
Recently a house hunt led me to do some HVAC research on the web. What I found is that HVAC techs have created a great community on the internet. Tradesmen and women from all over the world share stories, pictures, and videos on websites such as HVAC-Talk and HeatingHelp.

Culture Shock II, a robot by the Lawrence Tech team, first caught our eye due to its unique drive train. Upon further investigation we found a very well built robot with a ton of unique features.
The first thing we noticed about CultureShockII are the giant 36″ wheels. The wheel assemblies are actually unicycles modified to be driven by the geared motors on the bottom. The reason such large wheels were chosen was to keep the center of gravity well below the axle, providing a very self stabilizing robot. The robot also has two casters with a suspension system to act as dampers and stabilizers in the case of shocks and inclines. Pictured Below.
