Japanese Edition: 3Dプリンターで24時間以内に住宅建設。しかもリサイクル材料を用いたエコ建築。

3d printed house in china

by: [Hideyuki Yamamoto] based on this feature.

3Dプリンターメーカーが小さくて精度が高いプリンターを開発するのに躍起になっている中でShanghai WinSun Decoration Design Engineering Companyという中国にある会社がオリンピックプールの半分程度の大きさの巨大な3Dプリンターで実験を重ねているとBBCなどは報じている。

縦32m、横10m、高さ6.6mものマンモスプリンターで400m2の平屋一戸建て住宅がプリント出来る。FDM技術によりセメントと建築廃材混合の壁が作られ、その会社によると一軒あたり5000ドル以下で建てられ、1日あたりなんと10戸の製作が可能とのこと。

そのプリンターは数年前に設計され、WinSunが海外から部品を調達し、蘇州工場で組み立てられた。
この会社は街全体の家をプリントする計画を立てており、リサイクル施設を建設するための部材を集めているという。この家は、まずは青島にて販売される予定だ。

FDM技術を使えば軽量で耐久性のある家がプリント可能になる。この手法は間違いなくオランダのKamerMaker社による建築よりも早いであろう。耐久性や安全性に関してはまだまだ改善の余地があると思われるが、安くて短期間に家が建つ可能性が拡がる話題である。

Raspberry Pi Becomes a Universal Translator

hola-me-nombre-david-conroy

We’re still about 150 years away from the invention of the universal translator by [Lt Cdr Sato] of the Enterprise NX-01, but [Dave] has something that’s almost as good: a speech recognition, translation, and text to speech setup for the Raspberry Pi that theoretically allows anyone to speak in sixty different languages.

After setting up all the Linux audio cruft, [Dave] digs in and starts on converting the guttural vocalizations of a meat speaker into something Google’s speech to text service can understand. From there, it’s off to Google again, this time converting text in one language into the writings of another.

[Dave]‘s end result is a shell script that works reasonably well for something that won’t be invented for another 150 years. The video below shows the script successfully translating English to spanish, but it should work equally well with other languages such as dutch and latin, as well as less popular language such as esperanto and french.

Real Life Subtitle Glasses

[Will Powell] sent in his real-time subtitle glasses project. Inspired by the ever cool Google Project Glass, he decided he would experiment with his own version.

He used two Raspberry Pi’s running Debian squeeze, vuzix glasses, microphones, a tv, ipad, and iphone as the hardware components. The flow of data is kind of strange in this project. The audio first gets picked up by a bluetooth microphone and streamed through a smart device to a server on the network. Once it’s on the server it gets parsed through Microsoft’s translation API. After that the translated message is sent back to a Raspberry Pi where it’s displayed as subtitles on the glasses.

Of course this is far from a universal translation device as seen in Star Trek. The person being translated has to talk clearly into a microphone, and there is a huge layer of complexity. Though, as far as tech demos go it is pretty cool and you can see him playing a game of chess using the system after the break.
