It kills bugs and keeps perfect time. What's not to like?




It's not enough that humans gave robots a place to congregate to plan our demise, now we've adapted them with the ability to extract fuel from the very nectar of life. All that innocent experimentation with fuel cells that run on blood has led to this, a flesh-eating clock. This prototype time-piece from UK-based designers James Auger and Jimmy Loizeau traps insects on flypaper stretched across its roller system before depositing them into a vat of bacteria. The ensuing chemical reaction, or "digestion," is transformed into power that keeps the rollers rollin' and the LCD clock ablaze. The pair offers an alternative design fueled by mice, another contraption whose robotic arm plucks insect-fuel from spider webs with the help of a video camera, and a lamp powered by insects lured to their deaths with ultraviolet LEDs.

Just scale it up and make the entrance look like a Starbucks.

This won't end well for us. Soft, delicious, easily digestible us.

It's like we're actually TRYING to make man-eating robots that will destroy our society and exterminate the human race

You say that like it is a bad thing.

Nice try, SkyNet

The fast Hartley transform: faster than an FFT for real-valued data.


Whenever real-valued sample sequences need to be transformed into the frequency domain, the fast Hartley transform does the job in about half the time of the fast Fourier transform. The FHT algorithm is simple enough to code that there is little reason to resort to third-party libraries. With direct control over the implementation you can achieve optimizations that surpass the typical demonstration implementation.
