Spacehopper Demo

I’ve been working with my colleagues on a project for SonyEricsson around the release of their latest mobile phones series (Satio and Aino). The project involves using twitter to inflate a warehouse full of spacehoppers on a live webcam. The hoppers will be “released in the wild” as part of the product launch, and tweeters can suggest what their fate should be. The whole system uses an Arduino-controlled solenoid array which takes its input from a Ruby script which is listening to the twitter streaming API. Tweets sent via the API are used to randomly inflate one of the 49 hoppers on the array. The hoppers, username and the tweet message are displayed via a live feed. Sony Ericsson have posted the “making-of” video on YouTube, and I found myself simplifying the technical details, yet again…

Sometimes, the ideal little package comes along and you don’t have to do all the hard work fabricating a physical user interace. While working on the Spot-On project at LKL, I found a very nify little “finger torch” that solves the problem of powering up an LED in a small form factor. This little guy’s is perfect for retrofitting with an LD271 infrared emitter, for Wiimote hacking, IR Motion tracking, and generally mucking about moving around infrared sources, for you Johnny Lee fans. This package combines 3 button cells, a switch and an LED into a tight little case with a hook-and-loop strap. Not sure if it’s emitting continuously or in pulses (PWM) but there’s a microcontroller under that resin blob (pic 2), so it seems likely. A little de/re-soldering and, you’ve got yourself a perfect finger-mounted IR pointer!

Wow. It had to happen, of course. Shapeways have developed 3D printing in a material other than resin or polymer, the traditional materials for rapid prototyping physical objects. They can do it in stainless steel! The magic isn’t toooo surprising though, as they use the same techniques. Stainless steel dust is fused into a solid form layer by layer. The finished model is then bronze filled and baked. The piece comes out with a matte finish but can then be tumbled for a polished finish. They appear to be targeting the maker/craft community and I can think of a lot of fiddly parts that I’d need to make. But it’s still not as good as the 3D printer that the clever guys at EvilMadScientist Labs (rock on, guys!!) homebrewed, which makes 3D models in cane sugar!

Whenever the big kid on the block makes a new announcement, it’s a popular pastime to beat up on him. People have had a lot of fun beating up on Microsoft for years and now that Google have matured and become one of the biggest fish in the sea, they are a target too. I’m not worried about everything becoming Googlified, though, and moreover when they come out with interesting new open-source technologies like Google Wave, I get pretty excited. There’s been a wave of hype since they gave their preview at Google I/O 2009, and with good reason. This communication format promises to be as grounbreaking as email and will enable new kinds of social interaction, facilitated by real-time updating, sharing, editing and even…wait for it…Natural Language Processing. Imagine real-time chat translation in dozens of different languages. I always take any NLP announcements with a grain of salt, and to be sure this technology will have its teething pains. However, the demo is extremely exciting. (I’ve signed up to the developer’s list for updates.)

At the very least, if this technology catches on it will truly change the kinds of online social interactions that are possible and will make significant challenges to both current social networking stalwarts (Facebook, etc.) and the old standby desktop applications. I can see particular benefits for collaborative document editing, technology enhanced education, an dare I say it: Physical computing.

Since Wave uses an open protocol standard, anyone can develop for it. I’m envisioning online collaborative conversations actuating physical devices and real world sensors updating Waves. The possibilities are exciting!
