Carls entire channel is filled with really cool experiments in making PCBs do things people wouldn’t normally think of. There doesn’t have to be a practical purpose really, he just loves experimenting.&lt;p&gt;I really love his flexible PCB experiments too, he’s made a lot of awesome things from them.</text></comment>

I think it should be considered in this context.&lt;p&gt;If we start thinking about it in practical terms it stops making any sense. Specifically, a standard 2 layer board costs few $ to make. Here we&amp;#x27;re paying a huge premium for extra internal layers. You may as well take that money and put it towards a hob with an scr and a cheap controller to solder them on it.</text></comment>
