A Bayer array, or Bayer filter, is what lets a digital camera take color photos. It’s an array of tiny color filters that sit on top of a camera’s CCD. The filter makes it so that each sub-pixel in the image sensor only sees red, green, or blue light. The Bayer filter is an elegant

If you wanted an expensive film camera when you were a kid, you are in luck. Used film SLRs are super cheap now that everyone wants digital cameras. Of course, in reality, you want a digital camera, too. So do what [befinitiv] did. Make a film cartridge out of a Raspberry Pi that can convert your camera

Vishay VCNL36821S IRED Integrated Proximity Sensor is fully integrated with an infrared emitter, a photodiode for proximity measurement, and a signal processing IC in a single package with a 12-bit ADC. With a range of up to 30cm (12″), this stand-alone component simplifies the use and design-in of proximity sensors as no mechanical barriers are required to

If you have an old analog DLR camera you would like to convert to a digital camera you may be interested in a new project featured on the Raspberry Pi Blog which uses a Raspberry Pi zero and official Pi Zero camera to carry out the transformation. Created by YouTuber “befinitiv” the build replaces the

Posifa Technologies announced the new PAV3000 series of economical, high-performance air velocity sensors with digital I2C output and a surface-mount footprint for thermal management and filter monitoring in even the most space-constrained locations. Unlike thermistor-based solutions, the PAV3000 has a MEMS sensor core that is minimally affected by ambient temperature changes and which provides instant real-time feedback on
How much water have you had to drink today? We would venture to guess that the answer is somewhere between ‘absolutely none’ and ‘not not nearly enough’. You can go ahead and blame poor work/life balance — that’s our plan, anyway — and just try to do better. All this working from home means the

Introduction Our project aims to design a parking barrier modeling system with automatic number plate recognition.In our project, we used two Raspberry Pi. One for controlling the car stuck with printed number plate to move linearly toward the barrier and stop if it is not allowed to enter. The other is for controlling two Infrared
