An Arduino Uno (CH340G clone) reads temperature and humidity from a DHT11 sensor and computes 10+ environmental metrics (heat index, dew point, enthalpy, humidex, vapor pressures, etc.), outputting ...
Up until the last few years, heat-sensing cameras — think Predator vision — were a thing that pretty much only the Army and the super rich got to play with. Then FLiR figured out how to make the ...
While developing a vacuum system used for homemade PVD sputtering aparatus I felt the need of a simple and cheap vacuum gauge that can measure pressures as low as 1 Pa. I was not able to find online a ...
