Robot Arm is a Fast Learner

Not long ago, machines grew their skills when programmers put their noses to the grindstone and mercilessly attacked those 104 keys. Machine learning is turning some of that around by replacing the typing with humans demonstrating the actions they want the robot to perform. Suddenly, a factory line-worker can be a robot trainer. This is not new, but a robot needs thousands of examples before it is ready to make an attempt. A new paper from researchers at the University of California, Berkeley, are adding the ability to infer so robots can perform after witnessing a task just one time. …read more

A Tour Through the Archetypical Asian Factory

Overseas factories can be sort of a mythical topic. News articles remind us that Flex (née Flextronics) employs nearly 200 thousand employees worldwide or that Foxconn is up to nearly a million. It must take an Apple-level of insider knowledge and capital to organize such a behemoth workforce, certainly something well past the level of cottage hardware manufacturing. And the manufacturing floor itself must be a temple to bead blasted aluminum and 20 axis robotic arms gleefully tossing products together. Right?

Well… the reality is a little different. The special sauce turns out to be people who are well trained …read more

AV Synth is Psychedelic Analog Mayhem

Digital video is cool and all, but it can’t compete with analog in terms of smooth, creamy glitches and distortion. [gieskes] has developed an analog audio-visual synthesizer that is a great example of the old-school retro visuals you can create with a handful of simple components.

Known as the 3TrinsRGB+1c, it’s available both assembled and in kit form. It’s probably best to start with the manual. Synthesis is achieved through the use of a HEF40106 hex inverting buffer – a cheap and readily available part that nonetheless provides for excellent results. Video can be switched between RGB oscillators and a …read more

VinylVideo Is Literally Video On Vinyl

It’s often said that the music etched into a vinyl record takes on a transcendent quality that you simply can’t find in a digital recording, but does that still apply when you add motion picture? The collaboration of [Sengmüller and Diamant] sure think so, because they are offering a new experience for the turntable with the introduction of their VinylVideo pre-amplifier. No tape reels here, this project shows the extend of what is possible through analog video.

While all record players capable of playing back 7 in. 45 RPM are compatible with the system, the VinylVideo records themselves specially cut …read more
