Simple USB-C Breadboard Power Supply
May 25,2025
A simple "power supply" compatible with breadboards that should be able to output 3.3v@1A aswell as 5 volts. It is a really simple design consisting of very few components, mainly a voltage regulator and a couple of capacitors. On the PCB, there is a LED that indicates the device is recieving power. It is compatible with USB-C to USB-C chargers thorugh the use of CC pins on the board. This is one of my first projects that actually work :D

Simple & Versatile Arduino Kitchen Timer with TM1637 Display
Pavleski May 22,2025
 A kitchen timer is a simple, user-friendly device that counts down a set time and alerts the user with an audible or visual signal when cooking or baking tasks are complete. Most commercial kitchen timers are relatively complex to set up and operate, as more attention is paid to many unnecessary options and functions, while neglecting the simplicity of operation that should be a basic feature for a timer with this purpose.  In this project I will show you a very simple way t...

Sound Logic 2
Reboot May 22,2025
This 555 based board has 8 NAND gates and a 4040 binary counter.It has breadboard friendly headers and is intended to be used/configured using external components.An external resistor is needed to set the 555 oscillator frequency.Header pins include the 555 output, 555 control voltage input, 4040 clock and reset inputs and all Q outputs8 NAND gate inputs/outputsBy wiring up different configurations and creating various waveforms, sound effects can be generated.

RT DCC Booster
Ross May 16,2025
Based on this by D Bodnar:http://trainelectronics.com/DCC_Arduino/DCC_Booster_2/index.htmRather than using an Arduino Pro it uses an Arduino Nano.This is still a work in progress.

SINGLE CHANNEL RELAY MODULE
ZAFAR May 15,2025
This is a compact single-channel relay module PCB designed to control AC appliances using microcontrollers like Arduino or ESP32. I created it to offer a safer, cleaner, and more reliable alternative to bulky relay modules. It features a flyback diode, LED indicator, and screw terminals for easy use. The PCB ensures safe switching with optional optocoupler isolation. It's ideal for home automation and DIY IoT projects. I tested it by switching a light bulb using an ESP32, and it worked flawlessl...

Building an E-Paper Analog Clock with ESP32 - Full Tutorial
Pavleski May 15,2025
 In several of my previous projects you could see various unusual clocks , including several in the retro Analog style. This time I will present you another clock from this group, but now on a E-paper Display. Specifically, in this project I used the CrowPanel ESP32 4.2” E-paper Display module with built-in ESP32S3 MCU. I have this display from a previous project of mine and I can tell you that it is very practical in the sense that there is no need to connect components and solder, an...

Quarter-Round WS2812 Display
McEvoy May 14,2025
I wanted to make a clock that changed from green to red over the course of an hour to reinforce time passing. I wanted to avoid watching "just one more episode" or neglecting chores until bedtime.The quarter-round design makes the units modular, so I could put one in the corner of a window, two that form a rainbow, and four that make a circular clock.I assembled my clock using some laser-cut pieces, but the same parts could be made with hand tools. I also soldered wires to the back, but the Dupo...

ATmega328PB NANOx(PB) New and Improved Arduino NANO
Grigoriadis May 06,2025
I like the ATmega328 and I use it almost everywhere (except some special cases where I need more Power, then the ESP32 comes to help), it has enough Flash, Ram and Power for the Majority of my Designs. What I always missed was one more of every Interface (UART, SPI, I2C) as well as a couple of more GPIOs in the same TQFP32 Package. Few Years ago the Successor of the venerable 328P, the 328PB hit the Market, but I couldn't find any NANO Version of it (for Bread-boarding) on the Asian Market, so I...
