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.…

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 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.

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

In this video I do a review of my JABE soldering station. If you are looking for a decent soldering station that doesn’t cost you a fortune, this might be a good option.
Under review: Soldering Station JABE UD-1200. ( China Clone)
Purchased at: Alieexpress
Compared to JBC CD-2SQE ( professional precision soldering station )
Although buying a China clone of a good product might save you money, remember that an original product wasn’t developed over night.…

Thomas Edison was a great inventor who, amongst other things, improved the microphone for telephones by developing a carbon microphone. In ways, more than one, Edison contributed to worldwide communication.

This is a project you must see. A real must see Spectrum Analyzer up to 64 Channels!!!!
64 channels, how cool is that! I am using an ESP32 and a hub75 display. The use of pixelleds WS2812 is supported as an alternative for the display.

This Web based spectrum analyzer with ESP32 8-64 channels uses a ESP32 DEVKIT V1 and only 4 external components. Using the switch, you can select the number of bands you want to display on the webinterface 8,16,24,32 or 64 Uppon first boot, the wifi manager will kick in asking your WIFI credentials. If it doesn’t, you can force the manager to start by holding the mode button while rebooting.

I did a side to side comparison of a Analog based Spectrum analyzer and a FFT based one.
Based on performance, can you replace your double MSGEQ7 setup with a ESP32 and FFT library?
I compared both versions with a line input and a Microphone input and combined all in a video.
To compare, I used the same code( Sketch) but both with it’s own plugin to get the frequency information. So, one uses a FFT libary and the other uses my existing hardware with two MSGEQ7 and Frequency board.…
