![]() ![]() But an Arduino is just too strapped in specs to cut it! The effects of sampling and digitization are too restrictive. I’m think a nice real-time DAQ controller (like the ones offered by NI) could work here. And you want a fast solenoid to be able to control the levitating object! Unless you can have a large solenoid inductance and a rise time in the order of ~100ms, there’s no way an Arduino implementation can control this. The dynamics are very fast because the solenoid is fast. This project WILL require you more than a 10-bit ADC and more than 3-5 kS/s. DON’T try fancy control techniques if you don’t have fast and accurate hardware.It is in the link below: Full 11-page report with all the dataīut if you don’t want to read all of that, here’s a list of practical traps I learned during this project: Christian Hubicki was kind enough to let me pursue this as a graduate course project in Advanced Control Systems class at FSU, so I ended up with a “project report” on it. So here we’ll explore why people spend so much time tweaking their setup and what are the traps along the way.īut first, some results to motivate you to read further: You see these projects of floating stuff around the internet, but nobody speaks about what goes wrong. And boy, I thought it was an “easy” project. Of course, if I’m writing about it is because I went through the engineering exercise. Therefore, engineers and scientists are the true real-life wizards.“ “Any sufficiently advanced technology is indistinguishable from magic. So let me complement his quote with my own thoughts: Who creates the technology? The engineers and scientists all around this world. Because, if the advanced technology is indistinguishable from magic, who creates the technology is a real-life wizard. This is what led me to the Engineering path. ![]() “Any sufficiently advanced technology is indistinguishable from magic.” Clarke, who wrote “The Sentinel” (which later on became the basis for the science fiction movie “2001: A Space Odyssey”), goes along the lines: A floating light bulb that powers on with wireless energy? What a time to live!Ī quote from Arthur C. Some of which will even float a circuit that can light an LED and become a floating light bulb. Yes – You can go to today and buy one of these gimmicky toys that float a magnet in the air. ![]()
