HV power supply with tube and semiconductor curve tracer controlled by a Raspberry Pi with touch display.

Remote display of domestic water meter with consumption analysis for quick leak diagnosis. ESP32-OLED, WiFi, Web server, IFTTT.

Navtex, navigational telex, transmitted on 518 kHz is mandatory on commercial craft, but can be useful for leisure craft as well.

Here we present a specific application with a weather station built around the ESP32, which makes all data directly available online.

I have made software for YDLidar for use on PC with C, Python and Visual Basic, but also for use on Raspberry Pi, esp8622 and even Arduino Uno

Every day we throw away usable power alkaline cells. Since the device in which we use them can not work with partially discharged cells, the circuit that I present can raise the voltage of one exhausted cell to 5V to use it in any other application, for example to turn on a led, feed a microcontr...

The goal of the machine is to put/cut music on a vinyl.
