5 Dangerous Things You Should Let Your Kids Do

I did almost all of them when I was a kid, except superglue my fingers together. I had a few pocket knives but my favorite was the Swiss Army knife. This is what I use today to void product warranties:

Kano Computer: In A Word, Wow!

Oct 08 2014 | comment(s)

I've lost count of how many computers I've built over the years, but I think it is safe to say that the Kano Computer was the easiest build ever. So simple a child could do it. Kano founders, Yonatan Raz-Fridman, Alex Klein, and Saul Klein, wanted to figure out what the next generation’s computer would be like, so they asked Micah, Saul’s seven-year-old son.

Robotics: 555 Timer H-Bridge

Sep 25 2014 | comment(s)

You can build a simple circuit using two 555 Timer ICs to create an H-bridge that will drive a single motor in forward or reverse. An H-bridge circuit is often used in robotics to reverse the polarity of a motor. For example, if the motor is spinning in the forward direction, the robot will move forward and when the polarity of the motor is reversed, the motor will spin in the opposite direction and the robot will move backward.

The diagram of the circuit resembles the letter “H” where the motor is the cross-bar and four switches form the legs.

Solution to Last Week's Puzzle

Sep 18 2014 | comment(s)

Play the video below to see how to solve the puzzle I posted last week:

The object actually appears as it is pictured. It is not an optical illusion. The image was not created using an “in camera” special effect (no special lighting, no filters other than the built-in infrared filter, no mirrors, or any other “in camera” special effect technique). The image has not been modified with digital photography editing software. The object was not taped, or glued, or otherwise fastened together. The object was created using a single piece of ordinary twenty pound bond computer printer paper and a pair of scissors. Are you able to solve the puzzle of how it was made?
