thank you, that's my goal, looking for affordable strobe with x-fast strobe duration. no other light sources, as i try it in total darkness. i heard Xenon tends to be faster, but i found documentation indicating LEDs can accomplish the same. hard to find documentation about each product and its...

i hope someone answers my question here, otherwise i can ask in another thread: the 24-LED strobe light i bought does not adequately Freeze Frame the particles i use that blow around inside the 6-inch sphere, and even less so the particles moving around in the 4-inch sphere. would a stronger...

to follow up, i got this, plenty of air, just what the doctor ordered/FYI: https://www.amazon.com/gp/product/B07G5KM1DM/?tag=pfamazon01-20 now, still need to use a variable speed controller for it: https://www.homedepot.com/p/Broan-Electronic-Variable-Speed-Fan-Control-in-White-57W/202905912...

beyond my current scope of instrumentation, but great idea! will reply with results from Squirrel Cage fan, and Mattress pump. meanwhile the small, powerful 50mm cpu cooling fan worked only ok/shows promise, only after fitting a conical shape of semi-rigid card stock paper [ah, junk mail flyers...

thx, All! just ordered a squirrel cage, need to convert the rectangular opening to round, should not be that difficult. but also, a question - will an aquarium water pump also pump simply air? anorlunda - lol, that's the thing, that works perfectly, i tried it, and need something equivalent...

I have a 4 inch sphere with a 22 mm opening. Inside this sphere I will have 3 styrofoam balls 20mm diameter each and 3 styrofoam balls about 5 mm each. I need a wind source to blow wind into the ball through a tube approximately the diameter of a drinking straw, the wind being strong enough to...

hi there, i have always loved Science, and from astronomy transitioned into particle physics because of the Higg Boson, learning about the implications of Dark Matter, and Dark Energy. i am also studying things like Zero Point Energy, have always been fascinated with the flight dynamics of...
