SKIP THE RADIO WITH THIS SOFTWARE-DEFINED ULTRASOUND DATA LINK

We know what you’re thinking: with so many wireless modules available for just pennies, trying to create a physical data link using ultrasonic transducers like [Damian Bonicatto] did for a short-range, low-bitrate remote monitoring setup seems like a waste of time. And granted, there are a ton of simple RF protocols you can just throw at a […]

ARDUINO POWERED MISSILE SYSTEM USES ULTRASOUND TO AIM

ARDUINO-POWERED MISSILE SYSTEM USES ULTRASOUND TO AIM

In the real world, missile systems use advanced radars, infrared sensors, and other hardware to track and prosecute their targets. [Raspduino Uno] on YouTube has instead used ultrasound for targeting for an altogether simpler desktop fire control solution. This fun build uses a common off-the-shelf USB “missile launcher” that fires foam darts. To supply targeting data

Impact, vibration and ultrasound sensing with PVDF Piezo sensors

This post is about an interesting, low-cost sensor that doesn’t need much processing to use, and has some unique characteristics – a PVDF (polyvinylidene difluoride) Piezoelectric sensor. The sensors looks like a small strip of plastic, and can be used for detecting movement or vibrations even into ultrasound. Such devices can help sense in many
