Arduino VFO Project with a Large LCD Display
Pavleski Jan 16,2025
 A Variable Frequency Oscillator (VFO) is an electronic oscillator whose output frequency can be adjusted or varied over a specified range. It generates periodic waveforms, whose frequency can be dynamically controlled. VFOs are crucial in a wide range of applications, particularly in communications, testing, and signal processing. In one of my previous videos I presented a way to make such a device with an ESP32 microcontroller on a color TFT display. This time I will present you a V...

Skyviewer: a new way to look at the sky
Antonio G. Jan 15,2025
INTRODUCTIONWhat is the SkyviewerThe Skyviewer is an autonomous, portable stand for phones that can reliably orient the camera phone to take perfect shots of any constellation without fancy equipment or expansive cameras. It in fact works mainly with phone sensors, however without losing in personalising, as the star catalogue is fully changeable, as I will cover later in this section. I had the idea during the final of the Italian astronomy championship, where I started getting into rudimental ...

Exploring the Tesla Coil Driver Board, Full Review & Test Results
Pavleski Jan 09,2025
 Some time ago I presented you a video in which I analyzed a super cheap Tesla Coil driver that cost less than $20. This time I will also present you a relatively cheap other type of driver that costs about $50, but is complete and contains a half-bridge circuit with two power mosfets with appropriate heat sinks, as well as a full-wave rectifier. In short, in this case I only need the coils, the primary and the secondary to assemble a functional Tesla Coil. In this particular example, ...

Arduino Eatrthquake alarm and protection system with D7S seismic Sensor
Pavleski Jan 02,2025
 Earthquakes are extremely common events around the world. On average, there are fifty earthquakes a day, around twenty thousand a year. Many are mild and go unnoticed, but some are catastrophic. It is not always possible to predict when a disastrous event will occur. Using special sensos, designers can make their systems safer and minimise the risk of secondary damage from earthquakes by safely shutting down critical devices and halting their operation. In this project I will describe a de...

3D Printed Goldeneye Timed Mine (with Arduino)
Projects Dec 30,2024
IntroductionI previously made the remote mine and proximity mine from the movie and Nintendo 64 video game Goldeneye. The set would not be complete without the timed mine, so I spent many evenings designing and making the remaining prop.It uses a rotary encoder to set the time, a 4 digit 7-segment display to present the time, LEDs to show the status, and a piezo buzzer to signal the countdown's completion. With many components in a small housing, I used a custom PCB for the electronics.Materials...

UFO 50 SNES Style Controller
Barrett Dec 25,2024
I wanted to make a controller in the style of the UFO 50 controller to try and learn KiCad for the first time. The KiCad side was very easy, but 3D printing buttons that felt any good was kind of a hassle! I also wanted it all to fit together with friction and not require any screws to attach anything. I don't know why I wanted this, I just thought it would be fun.In order to get the look right from the UFO 50 reference images, I had to reduce the indent on top and print a face plate in a differ...

3D Printed Theo Jansen Style Octopod Robot (Arduino Based)
KILIC Dec 25,2024
Hi everyone! In this project, I will show you an amazing eight-legged robot in the Octopod style! It is made entirely from 3D-printed parts and moves with a cool mechanism inspired by the Jansen Mechanism. Two simple DC motors power the legs, allowing them to move in a smooth and balanced way. A simple Infrared sensor circuit and controller were used to control the robot. I will start the project by assembling the 3D pieces step by step, just like a puzzle, so let's get started!Step 1: 3D P...
