Tiny ARM-Based Sensor System Makes Battery Replacement Obsolete 96

Posted by timothy on Friday February 12, 2010 @06:46PM from the transcend-batteries dept.

An anonymous reader writes "University of Michigan researchers have crammed an ARM Cortex microcontroller, a thin-film battery, and a solar cell into a package that is only 9 cubic millimeters in volume. The system is able to run perpetually by periodically recharging the on-board battery with a solar cell (neglecting physical wear-out of the system)."

Directed Energy Weapon Downs Mosquitos 428

wisebabo writes "Nathan Myhrvol demonstrated at TED a laser, built from parts scrounged from eBay, capable of shooting down not one but 50 to 100 mosquitos a second. The system is 'so precise that it can specify the species, and even the gender, of the mosquito being targeted.' Currently, for the sake of efficiency, it leaves the males alone because only females are bloodsuckers. Best of all the system could cost as little as $50. Maybe that's too expensive for use in preventing malaria in Africa but I'd buy one in a second!" We ran a story about this last year. It looks like the company has added a bit more polish, and burning mosquito footage to their marketing.

According to the article, a team of 30 Google engineers is rebasing to the mainline kernel every 17 months, presently carrying 1208 patches to 2.6.26 and inserting almost 300,000 lines of code; roughly 25% of those patches are backports of newer features.

>>2. By posting it to the BB, he might have agreed to license it under whatever terms by which the board operates.

I've seen several 'boilerplate' BB services that actually claim submitted posts as 'theirs' for copyright, content, etc. This includes pictures, etc.

/. is 'rare' in that comments are owned by the poster per terms of service...
