Hans de Bruin’s DIY handsfree goggles allows you to record HD video of what you are seeing while having both hands free. He is using big safety goggles as the framework. He has removed the glasses and 3D printed an adapter that fits into the goggles frame and holds a video camera. He also uses a biconvex optical lens between his eye and the camera to enlarge the view of the LCD screen so that he could have a better view of what he is filming.

Measuring input signal frequency is a common requirement in many applications like tachometer, frequency meter, tone detection, etc. The two classic approaches of frequency measurement are measure the number of cycles in a fixed period of time and measure the time of one cycle. This application note from Cypress discusses the advantages and limitations of these methods and also presents a hybrid approach along with a sample project enabling measurement of frequencies with a typical error of 0.0016% (16 ppm).

Parking assistance systems are becoming a common feature in modern day cars to enhance safety and driver convenience. These systems use ultrasonic transducers and a microprocessor unit to compute the distance between the surrounding objects and car’s body. This application note from Cypress describes how to build an ultrasonic distance-measurement systems and provides a reference hardware design of a four-channel ultrasonic distance measurement system for parking-assistance applications.
