Electronics at Make Tokyo Meeting 07 #mtm07

These LED displays and circuit boards are assembled entirely inside a bottle. Amazing soldering work!

Below we’ve got lots of electronics goodness. An umbrella that turns rain into music, a force-feedback mouse, $13 DIY radiation detectors, bio-feedback jewelry, and more.

Dead-bug assembled batteries use liquid to power LEDs.

There were lots of Twitter-integrated projects. This uses a USB receipt printer to print Tweets about Make Tokyo Meeting.

This Twitter project takes a picture, posts it to Twitter, and then prints it out.

A force-feedback mouse. When you tap the ball the motors pull on wires connected to the mouse, giving the sensation of actually pushing against an object.

    1. I’m sorry, that’s the only one I have. I got to see him doing it though, puts my best SMD soldering to shame :)

  1. Is there any info on those ‘physical’ nobs? There is also a disney (?) Game that uses this principle to steer cars on an iPad

    About the soldering in the bottle I think I got some more.
