Solar sailer or just array of photoresistors This my little project to measure light. It has 6*8 photoresistors or pixels. So I can measure 48 different values. A longer-term idea is to make small photosensor. I’ve done a little python script and app to display data: a heatmap graph. What i learned so far IContinue reading “Solar sailer”

Lämmämõõdusk
Description A device that measures the ambient temperature in the environment in which it is located. And displays it on the screen. Artistic description Plant-like structures. Display like blossom. Bottom woodblock aged with brushing with a wire brush and oxidation solution (steel wool + vingar). Animations When the number to display changes it plays shortContinue reading “Lämmämõõdusk”
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”
Dust sensor
Nova PM sensor SDS011 can measure fine dust and smoke = particulate matter (MP) concentrations in two categories: Ultrafine dust particles with a diameter of 0 – 2.5 micrometres (μm/m3). Output PM2.5 Fine dust particles with a diameter 2.5 – 10 micrometres (μm/m3). Output PM10 The sensor is designed with a built-in fan to ensureContinue reading “Dust sensor”
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
Ultrasonic distance measurements – freeform circuit
If you stand in front of it, it measures distance between you and displays it.
Serial Plotter code
This is my standalone serial plotter. I like to use Arduino, Esp866 etc. and then i started to learn python and decided to make something useful. Something that i will use and what is missing now for me. Although Arduino Ide contains serial plotter. It is little bit different. Written in python 3 and Qt5.Continue reading “Serial Plotter code”
Serial Plotter
My first try to make useful GUI application a Arduino Serial Plotter Simple serial plotter for Arduino and other devices to quickly visualize generated data. GUI is made in Python3 + Qt5 . Much work remains to be done. But this is a good start. https://github.com/taunoe/tauno-serial-plotter
Ambient light sensor TEMT600
TEMT6000 is ambient light sensor. It is sensitive to visible light much like human eye and has peak sensitivity at 570nm. Visible spectrum is 390 – 700 nm. The sensor can handle voltages from 3.3v and 5v. The sensor has been designed into a voltage divider circuit. To read that voltage connect SIG pin toContinue reading “Ambient light sensor TEMT600”
Electronic “paper crane” or orizuru – freeform circuit
I had a bunch of smd LEDs and no idea what to do with them. But then, when I had watched all these events in Hong Kong. And when I had seen how they make this paper cranes I decided to make my own version. It use ATtiny13 AVR microcontroller and software PWM to slowlyContinue reading “Electronic “paper crane” or orizuru – freeform circuit”
