https://www.youtube.com/watch?v=vDyo_OQFdAc I doubt that you read comments that come years after you make a video. But I will leave this in case anyone wants to try to improve on this. I think it is a really good idea and there are lots of tools and methods to improve on it. Particularly for humans, but for

https://www.youtube.com/watch?v=oqLhvg0I2BU Your microphone link says that particular model is “discontinued”. I use Amazon for convenience and there are several electret microphone items worth seeing at https://www.amazon.com/electret-microphone/s?k=electret+microphone They have the electret microphone elements, but there are also some “electret microphone amplifier” breakout boards that are inexpensive and might work. I ordered some, but have not tried

https://www.youtube.com/watch?v=IhG_qHAvJd0 Fairly certain there is not enough information from one magnetic sensor to uniquely determine the position and orientation of the floating magnet. Once you actually measure the position and orientation of the levitated mass, its magnetic field, and the shapes of the supporting field. Then it is much easier. Do you think those rockets

https://www.researchgate.net/publication/3340967_Industrial_applications_of_pulsed_power_technology_IEEE_Trans_Dielecrt_Electr_Insul/comments Thanks for gathering this together. But the last decades or so, the cost of high power, high dI/dt controls has dropped considerably – drones, 3D printers, PWM servos, robotics, vehicles. I have only looked at a few areas so far. What you sort of missed was the sensor and control and modeling side. Atmospheric

The latest possible technology that I will be trying to adapt is related to piezoelectric films and piezoelectric fibers. I have seen several efforts to use piezo disks, but not these films. As I am reading the history of these materials

When I was at the University of Maryland at College Park in the late 1970’s I met Joe Weber and Charles Misner and others who were starting gravitational wave detection. So I have followed it over the years. I think it very unlikely that aliens would be using the very narrow band of electromagnetic signals

Karen Lee-Waddell, Pete Wheeler, SKA web contact, I am trying to piece together the Internet data sharing policy for SKA from what is visible on the Internet. Is SKA data going to be available to everyone on the Internet? In accessible form? Reading these it seems SKA data is only for certain people for very

Hello, I was enjoying your model site. One of the better ones on the Internet in terms of ease of use and clarity. The only thing that I would like different is to have parameters in the generated URL, so that I can bookmark a run and go back to it again, without manually entering

Luis, This was a good presentation. On Vimeo, watching reruns, no way to say “Thank you to the presenter” or to ask questions. We live in a world where any author’s work might be available globally for all time forward. And, it they are living, the small matter of “time” it taken care of by
