My home environment and air quality monitoring system
We often hide the electronics in a box. And cases can be done well and nicely. But when our main interest is electronics then it is sad to hide it. That is way like to do it the opposite way. Sensors will measure particulate matter (Ultrafine dust PM2.5 and fine dust PM10), co2, TVOC, ambientContinue reading “My home environment and air quality monitoring system”
Matrix – freeform circuit
ATtiny13 + 8* 74hc595 Shift Registers. It have two modes: random matrix and binary counter clock. Code: https://github.com/taunoe/attiny13-shift-matrix
Joule thief candle
This is a basic Joule thief circuit. It uses one AA (1.5) battery. When batteries are almost empty. Then there is actually still lot of energy. And it squeezes all energy out of it.
Ultrasonic distance measurements – freeform circuit
If you stand in front of it, it measures distance between you and displays it.
