The isolated analog input module presented here is particularly suitable for industrial electronics applications. Sending analog signals from field sensors over long-distance cables is often difficult ...

Much to the chagrin of hardware tinkerers, the Raspberry Pi doesn’t have analog inputs on its GPIO pins. Sure, you can blink a LED with just a few console commands, but reading sensors with a ...

Input devices that can handle rough and tumble environments aren’t nearly as varied as their more fragile siblings. [Alastair Aitchison] has devised a brilliant way of detecting inputs from plumbing ...

No matter the control system that we may be designing, whether it’s a HVAC monitor, motor controller or simple IoT sensor node, the system must control IO. This includes reading and writing digital IO ...

The Raspberry Pi is all the rage for hobbyists in search of cheap, credit card-sized computers that can run a full PC operating system. Arduino boards have been around nearly a decade, meanwhile, ...

Microblogging is getting an old-school twist with Tweephone, an “analog” Twitter client that uses a rotary dial phone to send out your 140-character missives. Microblogging is getting an old-school ...
