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
This is an open source project, all schematics, software and building instructions are available for you.…

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.…

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

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.…

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.
