The 60s and 70s had been a good time for kitschy lighting equipment. Lava lamps, strobes, coloration organs, black mild posters — we had all of it. One significantly groovy gadget was a man-made rain show, the place a small pump dripped mineral oil over vertical monofilament strains surrounding a small statue, with the entire thing lighted from above in dramatic trend. If it sounds appalling, it was, and solely bought worse because the oil bought gummy by accumulating mud and particles.
Whereas this levitating water drops show appears to be like considerably related, it has nothing to do with that greasy lamp of yore. [isaac879]’s “RGB time fountain” is definitely much more refined and fairly entrancing to look at. The time fountain concept is easy — drip water from a pump nozzle to a decrease receptacle alongside a path that may be illuminated with flashing LEDs. Synchronizing the flashes to the PWM controlling pump velocity can freeze the drops in place, and even make them seem to drip up. [isaac879] took the time fountain concept a step additional by experimenting with RGB illumination, and he discovered that every one types of neat results are potential. The video under exhibits all of the coolness, like alternating drops of various colours that appear like falling — or rising — paint drops, and drops that merge collectively to type a brand new coloration. And behold, the mysterious antigravity cup that drips up and but will get crammed!
Allowances should be made for movies of tasks that use strobes, after all. The impact of this time fountain and related ones we’ve featured earlier than is tough to seize, however this one nonetheless appears to be like nice to us.
Because of [xamiax] for the tip.
