Basil growing: ninth day

The time-lapse video are an excellent way to acquire a new time perspective of our environment. One of the most common uses is to observe the growth of plants, creating videos that compress days in just a few seconds. If you want to create your own time-lapse video below we explain how you can do so using a mobile phone Android as an IP camera and a Raspberry PI for storage and further processing of the video.

Non-invasive AC Current Sensor SCT-013-000.

Non-invasive AC Current Sensors are a good way to measure real consumption without altering the electrical composition of the elements to be analyzed. They work by magnetic induction, so that the field generated in the cable, used to power the device, induces a current in the transformer integrated in the sensor. In this way we can know what the current is in the power cable and therefore the actual consumption of the device to be measured.
