We are a small company in the UK building interactive science exhibits for museums and demonstrations for science shows, and other odds and ends. The channel is cool things we have built or just want to show other people.
Thank you! Here is why Earth is so big, spherical, old, with a giant iron core, rocks on its surface and life: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-CM0Hi0YwAJA.html You will be banned from astronomy forums and discussions for presenting this, so be careful who you talk to.
@@daveansell1970 it works well with all kinds of music, just needs clear tones to showcase strong waveforms. But most us audiophiles would agree it all looks good.
Wow. I don't think most folks realize what a brilliant and novel mechanism this is. I just modeled this up in software to try to understand it. There is no human designed repeating mechanism that I can think of that accomplishes storing force and releasing it kinetically with even vaguely similar linkages (ok so a trebuchet is somewhat like this, but fundamentally dissimilar). I can't think of a single wind-up toy, robo-dog, crossbow, other similar kinetic weapon, car part, throwing machine, industrial machine, walking machine etc, that uses linkages like this. I could write paragraphs on why I think this is so novel, but just try to model it yourself and you'll see what I mean, the fact that the video model is using the very specific properties of strings for some of the linkages is critical, the efficiency of force transfer is amazing, and the angles are critical.
Mostly it was a case of dismantling the monitor until you can get around the edge of the screen and then slowly and carefully peeling off the polarizer the whole time thinking you will crack it. The issue was that the glue was quite strong, and the polarizer tore several times. I think white spirit may have helped (if you aren't british, petroleum based household paint thinners)
Any videos of the final piece? Obviously the next step is to weld fan blades/ducts to the top so it spins itself as it gets hot. Then a centrifugal governor to stop it going too fast. Etc ... Etc
Lol .. funny use of this would be just in a window. Anyone without polarising sunglasses would see a white screen. Everyone with sunglasses sees porn. Or Tom and Jerry. Or whatever. ;-)
I am looking in nature to design the ultimate shock absorber and I wonder if you think this mechanism could be a possible candidate? Thank you in advance.
@@perfrivik9932 suitcase is a normal object that viewers have a good reference of how it should behave, it is an enclosure/protection for the spinning mechanism, it provides a handle to hold, and has sharp edges which is a simple shape that's easier for viewers to interpret/gauge motion.
Good video presenting information that I haven't seen before. Just lots of fact sources mentioning they can jump high but without any actual description of why. It never gets relevant or interesting without the "why" covered.
on my quest to design and build a functional prototype "mach 5 speed racer" I would need this principle to get the vehicle to jump. it's the compression of the "spring" AND the shift of leverage that does it. thank you for amazing work. could we make a jumping strandbeest? how do bumblebees and beetles fly? if you are content with the answer, why doesn't gravity, momentum and inertia splatter them into goo with the amount of force required to do the things they clearly do easily everyday?
Looked up how Crickets and Grasshopper, jump so high first vid is a New York times video titled "Crickets can jump 50x there height here's how" then does nothing but show people recording them with ballet music saying "we can learn a lot about these creatures for robotics" never even explan why they can jump so high; then here's this video which is buried in the search results that not only has a great visual aid but gets to the point. Excellent Video
