It seems deceptively simple to establish galvanic isolation with the help of optocouplers between circuits that operate at different ground potentials. Optocouplers draw power from the isolated ...

"You can build circuits straight on to paper, even in a spiral notebook," says Jie Qi, a member of the High-Low Tech Group at the Media Lab. Here she explains how to draw your connections.

Professors Jennifer Lewis and Jennifer Bernhard at the University of Illinois have come up with a way to draw circuits with a pen. Not circuit diagrams. Any old pen can do that. No, the pen is a ...
