This is an overview of the build process of the device. I will explain the electronics in detail in follow up videos.
Get the source code for the microcontroller and a stripped MIDI code version from my hompage electro.bitluni.net/midi
You have to excuse the low video quality. I didn't have the HD-camcorder yet when I started the project half year ago.

![LED Matrix Lamp made with a Budget 3D Printer [ANet ET4+]](https://i.ytimg.com/vi/enSusqJBnFk/mqdefault.jpg "LED Matrix Lamp made with a Budget 3D Printer [ANet ET4+]
This video shows a short test of the ANet ET4+ 3D Printer. It provides some cool features that allow continuing after power off and changing the filament mid-print. I tested the filament change to print a functional lamp case for a simple 16x16 pixel RGB LED matrix. The lamp is driven by the ESP8266 and WLED. It can be controlled over WiFi and used for several IoT purposes.

I tested the plan to utilize hourly ETEX power market prices to minimize my power costs. As power storage I tested the Oukitel ABEARL P5000 Power Station. The 120V MPPT solar inverter turned out to be the MVP.
