Of course you can use it to film anything you want. The author of the project, not having a suitable video camera, decided to use a Raspberry Pi. Several tests were carried out regarding the camera but in the […]

As fruits and vegetables ripen, they change color due to the four families of pigments: chlorophyll (green), carotenoids (yellow, red, orange), flavonoids (red, blue, purple), betalain (red, yellow, purple). These pigments are groups […]

The seismograph works autonomously in the field, or it can be used as a seismic station. […]
