Comment on Build a pedal powered generator by Premium Raspberry Ketone Review

David writes – “Every morning, I pedal to generate electricity. The Pedal Generator charges batteries, that run an inverter, that produces 110v AC, that powers LED lights, the monitor on my computer, and many other small battery-powered things. It is the most inspiring workout you can imagine. “ [via] – Link. There are plans available for purchase on the site for $50 – if anyone built one of these post on up in the comments.

Comment on the USB hourglass by ANARC random number generator

This is my random number generator new favorite (old favorite: lava lamps):

It monitors falling sand in an hourglass with an optical sensor. These data are sent via the Arduino USB output to the computer where it is parsed. This entropy is useful for all your random number needs. My favorite part: when the hourglass runs dry a servomotor it tip over and it starts again.

Machine to Peter Allan, said:

With the USB hourglass, the user can watch the sand falling through the center of the hourglass and monitor the shuffle in the USB output data. And you can read the code line by line, compile it and upload it to the microcontroller using only open-source tools and widely supported.

[Thanks, Scott Burris!]
