DIY Ultra Sensitive Theremino-Arduino Polygraph, Scientology E-Meter
Pavleski Jul 19,2024
 A polygraph, commonly known as a lie detector, is a device used to measure and record several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person answers a series of questions. The basic parameter on the basis of which the reliability of the response is determined is the galvanic skin conductance. The device presented in this video is basically a galvanic skin conductance meter with several additional advanced functions and setting...

Wand of Illumination
Arnov sharma Jul 18,2024
Greetings everyone and welcome back! This is the "Wand of Illumination," a 3D-printed wand combined with a flashlight incorporated inside.Utilizing one of the Harry Potter wands as a model, we have created a new wand from scratch. Inside the wand, we then installed a fully operational flashlight circuit.An Attiny13A 8-bit microprocessor connected to a switch that toggles the white 5mm LED makes up the flashlight circuit. A 3.7V, 50mAh LiPo cell that we added inside the wand serves as t...

VGA-AVR: An Arduino-Compatible VGA Shield for AVR Microcontrollers.
Net Jul 17,2024
The VGA-AVR is an Arduino-compatible shield designed for outputting video to any monitor and receiving data from any keyboard with its onboard VGA connector and PS/2 6-pin Mini-DIN connector. The shield was designed originally for hobbyists who wanted to make something retro and useful with their Arduino, particularly those who wanted to replicate the technology of the 80s, such as the Apple II and the Commodore 64. It would be nice if anyone develops some software for this shield but it support...

Slot Car Lap Counter with Advanced Features
unmessed Jul 16,2024
It is a lap counter for model race tracks. The project contains many interesting features that we can use as a basis for further projects and it is worth taking a look for that reason alone. The project is now ready for you to be replicated. In addition to standard functions, such as lap times, average, speed, etc., we have gradually implemented functions with a real wow factor that are truly unique: The lap counter is controlled via a fast web interface or via push buttons, ...

DIY addictive Arduino 1D Pong game
Pavleski Jul 12,2024
 Pong is a table tennis–themed 2 dimensional graphics arcade video game manufactured by Atari and originally released on 1972. This time I will present you a simple way to make a 1D LED Pong game which is an interesting project that simulates a Pong game on a single-dimensional array of LEDs. This can be done using Arduino microcontroller board. The movement of the ball is simulated by the array of LEDs, and the paddles are the two buttons. The game is for 2 players, in which the "ball...

Non-contact high temperature alarm using TS01 sensor
Tutoriales Jul 09,2024
The TS01 non-contact sensor high temperature alarm is a system designed to detect and alert about dangerous temperature conditions in various environments. This system uses the TS01 sensor, which is capable of measuring temperature without the need for physical contact with the object or environment to be monitored.The TS01 sensor uses infrared technology to capture the thermal radiation emitted by the object and convert it into an accurate temperature measurement. This enables contactless detec...

DIY Analog VU meter with Arduino peak meter
Pavleski Jul 05,2024
An analog VU meter, or Volume Unit meter, is a device used in audio equipment to display the level of audio signal in decibels (dB). It is commonly found on audio mixing consoles, amplifiers, and other audio equipment. The primary purpose of a VU meter is to provide a visual representation of the audio signal's amplitude, helping users monitor and control the signal level to prevent distortion or ensure proper recording and playback. Despite the prevalence of digital meters, analog VU meters are...
