“Sketching” Electronics With Conductive Ink

Conductive Ink, magnetic paper, Arduino Lilypad, and more.  Draw real electronic circuits on paper, instead of using an solderless breadboard, wirewrap, or a PC Board.  A series of videos…

“Sketching” Electronics With Conductive Ink

The first video I had to open in UTube to see.  The rest worked right in the original page.

Getting closer to ‘desktop factory’ all the time.

Printing ‘small’ parts at high resolution.

The world’s smallest 3D printer

From the picture, it looks like that connects to a computer through a standard [old style] serial cable [not USB]

The video says he built if for about 1500 € [in parts?], at todays conversion, that would be just over $2000 Canadian. He said it has the capabilities of a 60000 € commercial printer [$81100] !!

I’ve been following the online AI class from Stanford.  Included in that was a video with descriptive commentary of the robot that won the DARPA challenge.  The video is also on youtube.  The ‘trick’ was to overlay very accurate but short range laser sensor data, with much less accurate but long range camera vision, to ‘infer’ what was further ahead than it could see with the lasers.

Navigating beyond the reach of GPS

Found an article about some research to allow navigation / position detection where GPS does not work.  Bigger systems already use this technology, but the research is to develop it for use on small resource and battery life constrained devices, like cell phones.  That will also apply to small, mobile, indoor robotics projects.
