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”

My God’s clock project was published on HackSpace magazine issue 37. (https://hackspace.raspberrypi.org/issues/37/pdf) More about my project can find here: https://taunoerik.art/portfolio/matrix/
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”
Using AI to colourize black and white drawings
I found this deep learning project. It is meant and trained to colourize old black and white photos. And it does a very good job. But what it does when I use black and white drawings? If the picture depicts a person it works pretty well. Although it loves yellowish red tones. But with otherContinue reading “Using AI to colourize black and white drawings”
Linux special permission bits
SetUID We can enable files to be run by the permission of the owner of the file. Like when we change password (command passwd). When you run the password command, its being run as root. The s stands for SetUID. When the s is substituted where irregular bit would be, it allows us to runContinue reading “Linux special permission bits”
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”
Typography exercise
The goal was to make a vinyl record design using only typographic elements. With one serif and one sans serif font: With two variable sans serif fonts: Sans serif + handwriting or display etc. font: With opposite colours: With primary tones: With secondary tones: With tertiary tones With similar tones: Monochrome: Colour + neutral toneContinue reading “Typography exercise”
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
Mechanical RGB colour mixing
This my little experiment to mix RGB colours mechanically. James Clerk Maxwell developed a tool to trick the human brain. By spinning the right amounts of red, green and blue on a wheel, it seems like the colours are melting together to white. With this experiment he could prove that what we perceive as whiteContinue reading “Mechanical RGB colour mixing”
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.

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”
