A Super-Size Functional Tribute To An Ultrasonic Sensor

Sometimes, it’s time to shut down the oscilloscope and pick up the cardboard and paints. Wondering why? Here’s a nod to an Instructable from CrazyScience that takes us back to the days of cardboard crafts. They recreate one of the most iconic components for an electronics beginner — an ultrasonic distance sensor — and the best part is, it remains fully functional after the rebuild!
This project is as simple as it gets, with detailed step-by-step instructions, and you can complete it using just a hot glue gun and a soldering iron. With basic materials like cardboard, aluminum foil, popsicle sticks, some mesh, and a single ultrasonic sensor to harvest the transmitter and receiver from, it’s an ideal project to tackle with your kids on a rainy day.
Now, the classic ultrasonic sensor joins the ranks of other resized electronics classics, like the 555 timer and the Arduino Uno. Unlike these, this project’s cardboard structure makes it even easier to build your own, especially with all the shipping boxes we tend to accumulate.
