Various DIY projects displayed their homebrew gadgets, media art projects and open source software in one place. Let me introduce some of exciting open source projects I have found.
BC9 is an open source gadget by BeatCraft, Inc. Based on the gumstix CPU board, it features an LCD controller, AC97 Audio, and a battery power regulator on one small PCB. Software, schematics and even gerber data of BC9 are planned to be published as OSS.
Damien is a debian-based linux distribution targeting old PCs. It is focused on use as a thin client. It is configured to run an X Window Server locally and acts as a old-fashioned X client, allowing users to run remote applications installed on a server.
Scratch is an interactive programming platform for children. It is developed by MIT Media Lab and distributed as an OSS. It enables easy-to-use visual programming of electronic toys and computer animations. There is also a website where users can publish their creative works. It allows to share them freely, also allowing others to remix their works. In Japan, a voluntary programming workshop called Scratch Kids Programming Group (こどもプログラミングサークルスクラッチ) is held monthly at MediaSeven media center at Kawasaki.
ParaNavi (パラナビ) is an open source parawing navigator for the Gameboy Advance platform. They have modified their GBA hardware to embed a GPS module to enable real-time navigation and flight logging.
Pandora System is an open architecture for connecting physical devices, micro-controllers, and PCs. In the demo, they have used an RFID reader to authenticate users in a web browser.
Nico Nico Douga
The Home-brew community at Niconico Douga (ニコニコ動画) also participated in this event. For those of you don't know this website, Niconico Douga is a popular movie sharing platform featuring overlay comment response. They have eagerly improved their works following advice from their audience. They also did a live stream of the event.
KETACLOCK is a digit-by-digit independent LCD clock. It is driven by infrared signals submitted from a controller unit located on the back. Each module can be configured to display a particular digit, allowing users to make their own composition of the clock.
"Ano gakki" (あの楽器) is a Niconico Douga community-driven musical instrument creation. It was originally a fictional gadget which appeared in a fan-made promotion video for Yamaha's Vocaloid software. (You need to register at nico-nico douga to see the video, but it's also on youtube)
Its futuristic look has attracted a large fan base, including home-brew lovers, who started to build a real version immediately. After only half a year, several groups have successfully created clones which look just like the one that appeared on the original movie.
For me, it was my first visit to this meeting, but it was convincing enough to start a DIY project myself. It's definitely worth going. I want to participate as an exhibitor next year.
