As a biomedical equipment technician [Adam Outler] equipment needs to be in top working condition. The emergency room staff were complaining about erroneous noise on the electrocardiogram and it&#8… ...

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

Raspberry Pi launched a follow-up to its Camera Module 3 with the Camera Module 3 Sensor Assembly. Now, Raspberry Pi users can put the camera sensors into their own custom form factors. The move ...

The Sensor is a small module that, when attached to your wrist, back, or gym equipment, measures speed, power, and a number of other atypical metrics to help you achieve beast-like fitness goals.

Raspberry Pi is now selling the sensor from its Camera Module 3 as a separate component. “Since its launch two-and-a-half years ago, our 12Mpixel autofocus Camera Module 3 has found a home in a wide ...
