I Deleted My Tahoe’s Torsion Bars for Something Much Better at https://www.youtube.com/watch?v=fOyuvd5epFg There are apps for your cell phone that record the data from the three axis accelerometer. So you can change the settings and run on a given road at different settings to see the change in the impulse response of the car to road

Cat and Plasma Balls at https://www.youtube.com/watch?v=XkJYY4dDdr0 The cat investigated all parts of the globe, power (it can smell the hands of the person on the plug most likely), and behavior (optical, response to touch and nearness, acoustic because its ears and nose can pick up more than our fat fingers) methodically. Its nose is rather

The Civic Went A Diet with a serious weight reduction https://www.youtube.com/watch?v=TiZm7Ucm3JQ I think you can take off the back doors and replace them with lightweight panels. This made me think, I wonder what would happen if you could buy a “barebones car”, like “barebones computer”? No interior, no heater or AC, then add components as

How To Make Ruby in a Microwave at https://www.youtube.com/watch?v=ybcdRQmQcHQ It looks like the aluminum wire is burning (oxidizing) to aluminum oxide, and melting some of the close mixture. If you use coarse grained aluminum powder, and mix with the oxides, it might work longer and more uniformly. The melting point of aluminum oxide is 2072

Hello, I was looking at all groups working on games on GitHub and came across this particle clicker game. http://particle-clicker.web.cern.ch and https://github.com/particle-clicker/particle-clicker “An addictive incremental game that teaches players the history of high energy particle physics” So you click, it pulls up a random diagram of a scattering event, with no associated data. Shows it

Jean, I want to find a contact image sensor CIS that has high dots per inch, large color depth (bits per pixel color) and fast speed (lines per second). I need three of them, and don’t know where to buy the parts. I just started looking and found that the mobile document scanners (Brother) seem

A wave traveling between two parabolic antennas https://www.youtube.com/watch?v=v0cZjOIfwos You might try receiver-transmitter pairs, where each inverts the signal to build a standing wave. Use the final state inside the volume (arbitrary and time dependent if you want) as the constraint, then solve for the signal modifications needed at each site. I first saw this more

Two Scientists Are Building a Real Star Trek Impulse Engine https://www.youtube.com/watch?v=0bp8fk5rosI The software defined radios SDRs can transmit as well as receive. Most importantly the software for efficient FFT tracking and display is fairly well developed, so measuring and tracking the impulse response function from microHertz to GigaHertz is not so expensive. A solid, or

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

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
