Wiki says: The field of electronics is a branch of physics and electrical engineering that deals with the emission, behaviour and effects of electrons using electronic devices. Electronics uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering, which only uses passive effects such as resistance, capacitance and inductance to control electric current flow.
It's been a few years since i last upgraded my 3D printer. During this time a lot of new printer features were invented and several parts got cheap enough for me. Also my printer was havilly used and few parts started to show that thay are worn out. It's time for a bigger maintenance.
We bought an ordinary Ikea lamp Vidja to the living room. All lights in the room are connected to my home automation system, thus I wanted this new lamp to connect also.
I bought a new pair of shelves above the bed. Nothing special, just Ikea. But right after mounting them on the wall I knew, that I also need to add a lamp in form of a LED strip under them. And If I say a lamp, I mean a dimmable smart lamp connected to my home system.
It's a while I last did some hardware project and I had an idea of building a gimbal in my head for some time now. And suddenly I discovered somebody who was selling brushless gimbal motors for cheap. That was the first impuls. I ordered these motors and started to study what is needed to control the gimbal and started to design the construction.
The first version of my 3D printer was working fine, but as time passed, I found few things that could be improved.
I built my own 3D printer based on open hardware RepRap printer Rebelix X2, but improved by my own design customizations. Printer consists of plastic parts made by similar 3D printer (I used 3D printers at Czech Technical University), standard aluminium profiles, stainless steel rods and bunch of nuts and screws.
