The system monitors pH, TDS, temperature, humidity and water level. It also includes an air pump for oxygenating the plant roots and a PID controlled peristaltic pump for automatic pH adjustment (which pumps a pH reduction solution).
The Arduino Nano reads the sensor data and controls the air pump and the peristaltic pump, while the Raspberry Pi sends the data to InfluxDB and performs image recognition.
As you may know, mostly thanks to Arduino’s success and Massimo Banzi, the Maker Faire, self dubbed as “World’s Largest Show (and Tell) festival— a family-friendly showcase of invention, creativity and resourcefulness, and a celebration of the Maker movement” is finally coming in Europe. We’re not talking of a Mini Maker Faire (some have already…
Let’s optimize power consumption for our Arduino-like boards using specific hardware solutions and a dedicated software library. We recently had many requests about solutions to reduce power consumption for our Fishino boards, particularly from those – among the designers – who need to activate them for short periods of time: for instance, in…
We have been busy developing machines and optimizing their production. My favorite highlight is that we have reached a single day production time – for our automated Compressed Earth Brick (CEB) Press. Now we aim to reach this production speed for each of the 50 Global Village Construction Set (GVCS) machines. In my TED Talk, I…

Let’s learn about an interesting educational platform that allows you to make and study a real multitude of electronic circuits and their applications. Among the techniques to approach students and very young people, the one of using ecosystems related to prototyping boards such as Arduino has proved to be very effective; next to it…
Last time we took a look at the WiPhone, back in the middle of last year, the ESP32-based Voice over IP (VoIP) phone was closing in on full funding on Kickstarter. Since then it’s been a bumpy ride for the project towards shipping to its backers. That’s to be expected, as scaling from a single prototype to a full scale…
