I am Bhairab Kr. Mandal, founder of "Free Circuit Lab" channel.
This channel is an extension to simple electronic projects, this is mainly focused to such viewers who are new to electronics world, don't need complex explanation behind the circuits, just want to watch and build simple circuits in two minutes.
Direct and to the point. Now anyone can make their own infinity mirror without having to sit through 30 minutes of 3D printing, cutting, wood carving, etc, just to see how this effect is done. This was a huge timesaver and proves just how easily these can be made. Thank you.
While you can get 16.8V out of an LM7812, most people in a 1st world country could get an LM317 to use instead, and yet either of them are not a good choice because due to being linear regulators, waste a lot of power as heat, heat that you also have to heatsink away as these TO220 package regulators are only good for about 1W worth of heat without a heatsink on them. SO yeah... don't do what is shown in the video except as a last resort emergency situation.
I haven't watched it yet, but it's definitely not a 2-minute project because you need both dark and reflective surfaces, cut the segment (or segments) both for the pieces of glass/acrylic/polished metal etc as well as the lights, solder and heat shrink, do any additional layers/patterns and then put it all together and hide the edges unless its omnidirectional (in which case it would be a lot longer). You can increase the depth until it's so small that you can't make out the layers, add more directions and patterns separately so that it doesn't mash together, but match up and continue where part stopped and then continues on the other side. I made the front of my PC like that and put mirrors lining the inside facing inwards and out. Looks like an actual portal to other portals leading to all of the internal components separately, rather than it all being mounted on a mobo. People can make something that anybody that knows how to plug something into an outlet and use a pair of scissors has done, or... do something complex that anyone doing it after you keeps on improving it and making it better until it's something not yet thought of!
