Projection Mapping in Motion Amazes

Projection mapping is pretty magical; done well, it’s absolutely miraculous when the facade of a building starts popping out abstract geometric objects, or crumbles in front of our very eyes. “Dynamic projection mapping onto deforming non-rigid surface” takes it to the next level. (Watch the video below.)

A group in the Ishikawa Watanabe lab at the University of Tokyo has a technique where they cover the target with a number of dots in an ink that is only visible in the infra-red. A high-speed (1000 FPS!) camera and some very fast image processing then work out not only how the surface is deforming, but which surface it is. This enables them to swap out pieces of paper and get the projections onto them in real time.

Hackaday’s 48-Hour Tokyo Speedrun

“The future is already here – it’s just not evenly distributed,” goes the clichéd [William Gibson] quote. Growing up on all the Cyberpunk literature and spending a more-than-healthy amount of time obsessing over [Fred Gallagher’s] Megatokyo series, I always imagined Japan to be at the very tail of this distribution. The place where the Future lives. Though it has been decades since the Bubble burst, and there’s no way this could still be the case, there was something romantic about believing it just might be. Thus, I opted for keeping the dream alive and never actually visited the place.

Not until a few weeks ago — [Bilke], one of our crazy sysadmin guys that keeps Hackaday.io alive, made me do it. He found these cheap tickets from LA, and the next thing you know – we were flying out for a 48-hours-in-Tokyo weekend. With no time to prepare, we reached out to [Akiba] from Freaklabs and [Emery] from Tokyo Hackerspace for some tips. By the time we landed, emails were waiting for us, with our full schedule completely worked out. It’s great to know that no matter where you are, there’s always a friendly local hacker willing to help.

Past the immigration, we took the JR Narita Express line into to the City that Friday evening. From there we grabbed a taxi because we couldn’t understand a word in katakana but then we hopped the JR Yamanote Metro line once we had figured things out. We checked out all the major places we had ever heard of (Shinjuku, Shibuya, Roppongi, Ginza…) because the jet lag was not letting us sleep anyway.

Sometime way past midnight, it hit me – Future Shock. But this was the kind I never expected…

Tokyo Hackerspace – Akihabara Station Video Tour

This is the kind of footage that makes our mouths water here at Hackaday. [Akiba] of Freaklabs has been kind enough to take us all on a video tour of Akihabara Station, a treasure trove for electronics hackers located in the Chiyoda ward of Tokyo. The highlight includes surplus stores, specialty electronics shops, and enough silicon to bring an engineer to tears. Rather than waste time reading about it, follow the link and check out the videos in stunning 720p.

Hackers in other parts of the world, what kind of stores and marketplaces do you have like this? Send us your pictures and videos of local marketplaces that cater to your hacking needs so we can show them off.

Power suit for Japanese farmers

power_suit

Researchers at Tokyo University of Agriculture and Technology have been demoing a new power suit. It’s intended to be used by people hand harvesting in the farm industry. The 55 pound device supports the worker’s joints as they squat and reach. Within three years, they hope to have the cost within $10K. We’ve seen quite a few power suit devices this year, but research has been going on for many years, as you can see in our power suit roundup.
