This is my simple one-button radio. One button to turn it on and change the volume. There are actually two buttons more: first to select a new channel and second one to save it to memory. It was a project that taught me how to draw PCBs, what are Gerber files and so on. IContinue reading “How i made my digital radio”
Tsõõri kujuline arvuti sisesndseade. Praegu on seadistatud see käituma nagu hiire kerimis nupp. Arduino Pro Micro saab programmeerida matkima kõiki USB seadmeid. Nagu see oleks hiir, klaviatuur või mõni muu HID tüüpi USB seade. Kood asub GitHubis. Eraldi on loodud teek pöördkooderi (Rotary Encoder) jaoks.
Tauno-Serial-Plotter is simple serial plotter for Arduino and others boards. Written in Python3. In the last few weeks, I have learned how to package my Serial Plotter app into Ubuntu Snap format and made it available in Snapgraft.io snap store. Also, I have a plan to make it available as a Flatpak. It took aContinue reading “Tauno Serial Plotter”
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”
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”
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”
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”
ATtiny13 + 8* 74hc595 Shift Registers. It have two modes: random matrix and binary counter clock. Code: https://github.com/taunoe/attiny13-shift-matrix
If you stand in front of it, it measures distance between you and displays it.
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”
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
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”
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”
