I think tutorials on how to build microchips would be a good tutorial. I was also using inductors as volatile memory storage(like ram) so you can use that in your circuits if you want.
But yeah if you want to, you should have a printing service where people can send you schematics for microchips and you can build them too.
but again supply people with software so they can test their designs.
the more tutorials the merrier. but yeah I was using inductors in each bit to store data for certain amounts of time. it changes the way the microchip looks but it can be done.
But im also working on analog computers too so ill have a lot of passive integrated circuits that will need printing too so i thought i would just throw this out there because it might further your business.
