ESP32 Fluid simulation on 16x16 Led Matrix
Pavleski Feb 20,2025
 Fluid simulation is a way of replicating the movement and behavior of liquids and gases in different environments. It’s widely used in fields like gaming, animation, engineering, and physics to create realistic visual effects and solve complex fluid-related problems. This time I will present you a very simple way to make a fluid motion simulator using a few components. This is a simulator with a relatively low resolution of 256 dots and for that purpose a Display made of 16x16 LEDs wi...

ATMega32U4 Breakout Board
Lastname Feb 15,2025
The ATMega328P (Arduino Uno) comes in a breadboard friendly DIP package, but the USB integrated 32U4 doesn't! This is my solution. It breaks out every pin of the QFP-44 package to a convenient pair of 22 pin headers. It also has a handy silkscreen pinout so you don't forget what's what.

Simple GU50 VTTC Tesla Coil with MOT (25+cm Spark)
Pavleski Feb 12,2025
 Vacuum Tube Tesla Coils are a common choice for homebuilders for several practical reasons. At Solid State Tesla Cioils in the case of incorrect assembly, incorrect calculations, or even incorrect wiring of printed circuits, field-effect transistors quickly fail, sometimes with explosions, which also entails financial difficulties, because powerful transistors cost a lot. VTTC have a much simpler circuit, based on one powerful Vacuum Tube, as in this particular case GU50 which is also much...

SIMA Mainboard
MIŠIĆ Feb 11,2025
SIMA (The small independent mobile actuator) is one of our projects for Eurobot 2025 competition. A microcontroller that we use on this SIMA is Arduino Nano, which is easy for programming and realisation of all small projects. We have two Ultrasonic sensors for control the movement of the robot, one small buck for convert the voltage to 5 V DC. We also use two FS511R motors for the movement.

KeyPROM Prototype
Coder Feb 11,2025
This early prototype makes use of an on board cryptographic co-processor to provide security functions and encryption for the data transfer,The co-processor will also be used to store the secure key for the encryption as well as a counter for HOTP to be sent with the authentication packet. There will be another project which will be the reader for this "key"

Hourglass ESP8266 Code
Pavleski Feb 06,2025
 A hourglass, also known as an sand clock, is a device used to measure the passage of time. It consists of two glass bulbs connected by a narrow neck, through which sand flows from the upper bulb to the lower one.  The flow of sand is controlled so that it takes a set amount of time to completely empty the upper bulb. Hourglasses are often used as time management tools and decorative items. This time I will present you a very simple way to make a digital version of such a clock. T...

Line Follower Robot using Arduino
Jain Feb 05,2025
A Line Follower Robot (LFR) is an autonomous robot that follows a predefined path, typically a black line on a white surface or vice versa. This guide will walk you through building and programming an Arduino-powered Line Follower Robot from scratch.How a Line Follower Robot WorksThe robot detects and follows a line using IR sensors. Black surfaces absorb most light, while white surfaces reflect it. The IR sensors, consisting of an IR emitter (LED) and an IR receiver (photodiode), use this princ...
