Smartwatch Fights Anxiety with Action

In our fast-paced modern world, it’s no wonder that so many suffer from anxiety and panic attacks. There are several time-worn techniques for dealing with the symptoms of these attacks. But as anyone who’s ever suffered such an attack can tell you, it can be difficult to sense one coming on until it’s too late. By then, rational thinking has been supplanted by intrusive thoughts. For this year’s Hackaday Prize, [Austin Marandos] is doing his part by using technology to help us check ourselves before we wreck ourselves with worry.

Similar smartwatches exist to detect oncoming attacks, but they don’t …read more

Find Your Way with Tiny Laser Beams

For their final project in embedded microcontroller class, [Aaheli, Jun, and Naomi] turned their focus toward assistive technology and created an Electronic Travel Aid (ETA) for the visually impaired that uses haptic feedback to report the presence of obstacles.

We have seen a few of these types of devices in the past, and they almost always use ultrasonic sensors to gauge distance. Not so with this ETA; it uses six VL53L0X time-of-flight (ToF) sensors mounted at slightly different angles from each other, which provides a wide sensing map. It is capable of detecting objects in a one-meter-wide swath at a …read more
