This hack shows how to make a dumb terminal out of a keyboard, LCD screen, and an 8-bit microcontroller. From time to time, a portable dumb terminal can be handy for when you have to rescue a headless ...

Often, you need to transmit a couple of bits or bytes of data to a microcontroller without a direct cable connection. One simple way to achieve this goal is to use a widely available IR receiver, such ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...

Sometimes a circuit requires a data link over an existing cable that doesn’t have any free conductors for a dedicated comm link. A common solution is to superimpose a high-frequency carrier modulated ...
