I am suggesting tutorials on the following. All passive components and prefereably vacuum tubes can be used to build the following circuits. Analog computers that are programmable and hopefully intellegent. with these you should process many signals at the same time. and instead of displaying results on an oscillscope, make a monitor and a gui. I have a theory for a power supply. I think it works im not technically able to build the entire circuit yet. It's all passive. its a passive AM radio that sends a 60 hz sine wave. then on the other end you have many many antennas attatched to a passive receiver circuit. because each antenna will induce an electric field from the air, you should be able to get lots more power out of the circuit than you put in. and because its antennas, its compact and light weight. And if you can figure it out, you can build plasma rockets too. I need some more information on how plasmas travel through an electric field. but you know if you want to, you can build cars, boats planes, houses, cookware, sensors, surveilance, recording studios, 3d printers etcetera in passive electronics and post tutorials on it. I am getting somewhat close to growing carbon based electronic components on a tree. I have some(a few) molecules in mind and I am starting to research and make progress on sequencing DNA. If you want this information it is simply yours. but I need analog flight simulators, spaceflight simulators, weather simulators that use chemistry and math to predict the weather, ocean simulators that simulate all of the bathymetry of the ocean to predict surf and erosion. aircraft designers. I have a motor that i am designing like the following. It only uses permanent magnets at the moment and it works similar to an alternator. If you can figure it out, you can build it too. I have an alternate way to make bearings by using cylindrical magnets(the kind with the hole in the middle) and one is attracting and one is repelling. this should be able to make it so that the magnets levitate and spin freely. Again if you want this information it is yours. YOu can also make analog computers compatable with software that exists today like linux. it is possible. it just takes some time and some thought. ANyhow anything you want make it wireless make it programmable and make it and post tutorials on it. I want EVERYTHING to be wireless from the computers to the recording studios to the rockets. ANyhow thanks and have fun and stuff and it might be fun and it would help everyone and would help your compnay to produce these tutorial but you know wireless guitars, wireless amps, wireless record players wireless cnc machines, wireless laser cutters wireless induction cooktops etcetera. you can even make a record player that instead of using that metal thing to vibrate, you can use like sonar. You know this is just some cool stuff to consider developing. The radio based power supply will work, it just needs some fine tuning and same with the motor, but yeah have fun and be easy with this stuff itll take a while. but you know if you build rockets, spin the rockets to create a strong electric field, but you know i could use tutorials on how plasmas move and accellerate through an electric field etcetera. and for god sake, build EVERYTHING!
