The last two years, I have been designing and building Audio Spectrum Analyzers and I sold more than 100 PCB’s. This means that more than 100 units where build successfully. I asked people to send in a video of their analyzer while playing a specific song. This video shows a compilation of some magnificent builds. It contains several versions from my oldest, the 14 channel MSGEQ7 analyzer to my newest, the 10 channel analog analyzer and everything in between.…

This Talking Clock is based on @Brian Lough Tetris Clock. I added a wav/mp3 player enabling you to play sounds at set times. I also added a webserver to change settings, two text tickers to send you message out to the people in the room and I included a function to use this clock even without access to a WIFI network. All in all, I added some extra features to a already nice design.
This video is sponsored by @PCBWay They make great PCB board and offer good assembly service.…

This is a VU meter/ spectrum analyzer that can replace some of the old analog needle’s….this is for the real audio lovers!!

This is my digital version of an old riddle. A Farmer needs to take a Fox, a chicken and a sack of grain to the market. On the way he needs to cross a river in a small boat.

How can the farmer get all items to the market? Depending on what country you are in, the version of the story might have different characters.…

To explain about his Talking Arduino Timer, Imagine working at the office from nine to five punching numbers in a computer the whole day…All you have, to hold on to, is your coffee break! Fortunately, it is not that black and white for most people. We do have something in common though. There is a time that each and everyone of us needs to take a bathroom break. At some point, all the coffee we drink needs to leave the body, doesn’t?…

Make music with this Stereo flyback ZVS driver. You can drive 2 flyback transformers to create a 2 channel sound ( Stereo ). You can use square wave music as the sound course.
It’s a fun little project that you can use to create awesome videos. Also, you will learn how to drive Flyback transformers; a technique that was used in old TV sets but if becoming less and less every day.

This is how I illuminate my achievements and I mean that literary. I took my diploma ( and my wife’s) digitalized it, engraved it and put it up my wall. It includes some light sensitive electronics that will illuminate the diploma accordingly.
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.…

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!
