Holding your phone up to take an occasional picture is no big deal, but for professional photographers who often need to manipulate heavier gear for hours on end, this can actually be quite tiring. With this in mind, Cornell University students Kunpeng Huang…

If you design printed circuit boards, then you will have also redesigned printed circuit boards. Nobody gets it right the first time, every time. Sometimes you can solder a scrap of 30gauge wire, f…

In this activity, students investigate water turbidity and how this can be monitored over time using electrical components.

Using cryptographic authentication, we created a super-secure remote control to open a garage!

The Qwiic MicroPressure Sensor is now available, along with a slew of new Flirc products!

As John Keefe notes in his project writeup, at-home pulse oximeters — which monitor the oxygen saturation in your blood — have been selling out due to the COVID-19 pandemic. While you could try hunt around and find one, he decided to instead make his own…

Sometimes you need the real-time interaction that only a meeting can provide. Keep family members from wandering in on your important meetings with this simple alert!
