How to build a Powerful but easy Tesla Coil

Posted on February 9, 2022 by Mark Donners

This Tesla Coil is based on the principle of a slayer exciter that I first encountered in a Russian design. That’s why I called it the Russian Slayer Exciter
This is a High voltage project and building and or using it can by dangerous. Electricity can kill you! This is not for beginners. This video is for educational purpose only. If you decide to build this or a similar setup, you do so at your own risk!
This is an open source project, all schematics, software and building instructions are available for you.…

Partnered with PCBway for upcoming projects

Posted on January 21, 2022January 21, 2022 by Mark Donners

I am happy to announce that I partnered up with PCBWay .

PCBWAY is sponsoring my PCB projects and some amazing builds are in the making. While you read this, the PCB are produced in a well-established factory and components are being assembled by PCBWAY’s assembly service. While they are working hard to help me complete my projects, I am working on the Arduino code while finetuning the hardware. Can’t tell you to much about it but I promise you those will include Arduino, very high voltage, Funny sounds and A game and a way of saving you the suffering of having to smell something nasty!Curious?…

Desktop Spectrum Analyzer with Analog Design

Posted on January 1, 2022January 4, 2022 by Mark Donners

This analog spectrum analyser with 10 channels uses an analog back-end to analyse the incoming signal from line-in or microphone. The analysed signals are then transformed to a memorizing light show by the front-end ESP32

This project includes an embedded webserver to display a real time analyser on web browser capable devices in your network

Build your own CO2 Laser Cutter – Part 1 orientation

Posted on December 20, 2021December 21, 2021 by Mark Donners

This is the first video of my laser build saga. I’ll be building my own CO2 Laser Cutter on a affordable budget. This video is my first orientation. After making this video, I ordered all missing parts and I will start building ( and filming the build) as soon as all parts have arrived.

This is a rebuild, building plan are not mine but they are available at the website from Further Fabrications.

This video has not been sponsored by Further Fabrication.…

Arduino Christmas tree

Posted on December 20, 2021December 21, 2021 by Mark Donners

This is a little project for Christmas. A nice Arduino Christmas tree, Arduino driven with 14 pixleds. WS2812. It’s controlled by a tiny arduino and although the software sketch is not complicated, the result is nice and shiny.

This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.…

Arduino Dream Catcher

Posted on December 20, 2021October 18, 2024 by Mark Donners

This project came my way when my daughter asked me to get her a Dream Catcher.
So, a Dream Catcher without electronics? NO WAY! So I spice it up using an ARDUINO and some NEOPIXELS.

This is an open source project, all schematics, software and building instructions are available for you. Use it, change is, heck even sell it. It’s ok but if you do one or more of the above, please give me credit by linking back to my channel.

How to make a powerful Tesla Coil high voltage Russian slayer – build your own

Posted on December 20, 2021December 21, 2021 by Mark Donners

This is a rebuild of a small tesla coil, directly powered by 230V outlet. Be warned! This is high voltage.
Touching any part of the circuit or even the output of the coil CAN KILL YOU. Rebuild and use at your own risk… Although that looks very cool, my main question was: “Really? And Can I build it?” This is an open source project, all schematics, software and building instructions are available for you.

Use it, change is, heck even sell it.…

Amazing Rubber band tommy toygun – Unreal Tournament at office

Posted on December 20, 2021December 20, 2021 by Mark Donners

I rebuild the Rotary Mek 10X Rubber band Tommy toygun, designed by Julian Marsh ( Rubbergunner on Youtube). Using his Book ( amazon) I was able to recreate his design. I changed some dimensions to fit local supply availabilty.

It can hold 70 rubber bands at a time and it is able to fire it all in about 3 seconds.

I brought this toygun to the office to surprise my colleagues. They Loved my Tommy Toygun
