Comment on The 49 dollar, 500 WattHour eBike Battery video

https://www.youtube.com/watch?v=0FwA_s9Ovxc You talk about motivations for watching and DIY at about minute 14. The reason I am watching is I have a lifetime of learning how things work, what they can do, and how to put them into different combinations. Often the off-the-shelf parts don’t fit, or are overkill or too expensive. Mostly they just

Comment on Video about laser interferometer design and use – replace superconducting gravimeters

Counting Atoms with the Doppler Effect – Heterodyne Interferometer by Sam Zeloof at http://sam.zeloof.xyz https://www.youtube.com/watch?v=vPu6lN9yJOY Sam, I sent you an email about using this to replace the network of superconducting gravimeters with something more people can afford. You have several orders of magnitude available to you by very small adjustments. SGs cost several hundred thousand and

Comment on Flywheel energy storage experiment video

Electrical tests! | 2 Mechanical Battery by Black Sahara at https://www.youtube.com/watch?v=uiOf_-0aFP8 I like what you are doing or I would not comment. Please get a stand for your camera. Learn to solder. Learn to use sound card oscilloscopes and spreadsheets. Keep up the great work!! Thanks for the videos!! Put a “support” “donate” button somewhere.

Comments on a video tour of Cern’s Atlas facility

360° tour: ATLAS Experiment – Inside CERN’s largest detector! https://www.youtube.com/watch?v=On1WbLKP8DA Dear Atlas at Cern: There are two purposes for a video like this. One is to simulate what physical visitors do and see if they ever have a chance to visit. You show the parking lot, door, elevator, tunnels, and things. You show things from

Comment on Optical fiber coupling to photonics chip

Optical fiber coupling to photonics chip by Wojciech Lewoczko-Adamczyk at https://www.youtube.com/watch?v=rHcfemtfP2s Suggest you use the whole screen for the graphs, equations, diagrams. It is too small to read easily and I do not need to see your face while you are looking at the screen. Such are called “screen videos”, where you and the viewer

Merging and upgrading sensor networks towards new industries and materials

Shawn, The atmospheric gravitational noise is much larger than the signals from the subsurface (usually). The noise in that gravimeter you want to buy is mostly atmospheric and thermal radiation field connected. Calibrate it against the sun and moon first. Then against 3D near realtime atmospheric models. (Climate and meteorology are just atmospheric, and the

Gravity and Temperature, gravity and pressure

Shawn, What I am saying is that the energy density of the radiation field of the earth, which you can map by mapping the temperature is just “gravitational field stuff”.  The magnetic field of the earth which you can convert to magnetic energy density is also made of “gravitational field stuff”. The gravitational field of

Comment on my video Windows USB GPS Device Based on UBlox Chip and UCenter Software

Windows USB GPS Device Based on UBlox Chip and UCenter Software https://www.youtube.com/watch?v=uJZHVKGrl6Y @Ali Zitouna Hamed, I am not sure what you mean by “base ntrip”. I made this long ago and have not used UBlox lately. Since then i have been working on software defined radios, electromagnetic interference, gravitational wave detection, imaging arrays for gravitational

Comment on Aerodynamic Center and Center of Pressure

Alexander, https://www.youtube.com/watch?v=67eTLeNwLgE You are using what looks like to be a good computer tool for these calculations and visualizations. But you don’t explain your tools and give links to let others know what to use, or what you recommend. I watched your hysteresis video. It is really shaky and hard to watch. You could use
