Yes, and I've seen closer even on YouTube recently. [VIDEO] The isometric view camera is neat though!
Read original comment ↗FWIW, there _is_ work being done on the hobby front for IC fabrication "at home". We're still far from buying a miniature chip-fab-in-a-box product, but current technology makes yesterday's tech far more affordable. We're on our way. Example: [VIDEO]
Read original comment ↗While it's not "easy", I was surprised to learn recently that DIY microprocessors are far more accessible than I thought. Here is BreakingTaps fabricating home made chips, he has a fair bit of equipment though [VIDEO] There a a few different techniques that can be used. Most of the lithography techniques use Hydrofluoric Acid, but if you are okay with slower build times you can etch the circuits directly with Ion beams or Electron Beams. But the short story is you need an overhead projector, a microscope, and a few gnarly chemicals. Otherwise fairly straightforward.
