automated farming system
Kurubaş Aug 04,2025
Our project measures soil moisture, air humidity, and temperature to automatically perform tasks such as soil irrigation, temperature reduction or increase, and moisture reduction or increase. This aims to reduce water usage and mitigate the effects of global warming.Note: We are a group consisting of two high school students and a physics teacher living in Turkey. We created this project for a competition. If you encounter any errors in the project,please contact us at mertarifkurubas1507@gmail...

330,000 volts (330kV) from modified PC Power Supply and Cockroft Walton Multiplier
Pavleski Jul 31,2025
 The Cockcroft-Walton voltage multiplier is a circuit configuration used to generate high DC voltages from a low AC voltage source. The basic Cockcroft-Walton voltage multiplier circuit consists of a series of capacitors and diodes interconnected in a ladder-like configuratoin. The circuit takes advantage of the fact that capacitors charge and discharge alternately when connected in series with diodes. It's typically used in applications where a relatively constant output voltage isn't requ...

More Bass Treble and Volume! With PT2313 DSP
Manoj kumar Jul 28,2025
When it comes to signal processing through a digital medium then DSPs are the one who comes into play. Basically here we are talking about audio signals and music. In the convention audio system there are analog systems consisting of a lot of opamp drives and knobs to adjust the different settings. A basic analog system may perform well but it is bulky and not realizable in certain places where we want a computer control. On the other hand these DSP units are cheap and easy to configure with a m...

Tiny Microcontroller Tester
Simple Electronics Jul 26,2025
A simple board to test out GPIO of your microcontrollers, using two rows of 0603 LEDs (one row for HIGH and one for LOW) and 0805 resistors.If you have NO IDEA which LEDs to use - I recommend GREEN leds on the column furthest from the pins (to indicate a logic HIGH), and RED leds to indicate LOW. I used 1k resistors for the red, 4.7k for the green.check out the video here:https://youtu.be/UdBXRT8gOx8You might need some parts:0603 LEDsAliexpress: https://s.click.aliexpress.com/e/_oC9FwTqUSA &...

Raspberry Pi Pico SSTV Decoder- Receive Images Over Radio
Pavleski Jul 16,2025
Slow-scan television (SSTV) is a method for transmitting and receiving still pictures over radio waves, primarily used by amateur radio operators. Traditionally, decoding SSTV signals requires a PC and a soundcard, but this project demonstrates a simpler, more accessible solution.  The project is completely taken from the 101Things blog and all credits go to the author of this project. There are many more wonderful radio projects on the same site and I hope to test and promote some of ...

Building a GPS Speedometer with RP2040-Zero
Iturriaga Jul 11,2025
Build a Feature-Packed GPS Speedometer with an RP2040This project guide will walk you through building a multi-function GPS speedometer and trip computer using an RP2040 microcontroller. It leverages a GPS module for real-time data and presents it on a color display through a clean, multi-page interface.Instead of a simple speed readout, this device provides five distinct data screens you can cycle through with a rotary encoder. It’s a practical tool for anyone who wants detailed metrics on thei...
