Smith] from the University of Washington, which purports to construct a low-throughput RF transmitter from little more than a resistor. This witchcraft is made possible thanks to Johnson noise ...

What the heck does a zero-ohm resistor do? Well, the short story (tee-hee!) is that it’s like a jumper for single-sided surface-mount boards. In the bad old days, companies used to save money by ...

When resistors are connected in series, the current through each resistor is the same. In other words, the current is the same at all points in a series circuit. When resistors are connected in ...

Messing around with Arduino can lead to some fun projects-- like simple electronic games, lighting or audio manipulation, or even gesture controls for other devices. However, you'll need the right ...
