Flash effects

A collection of different flash effects that could be programmed.

  • describe different configurations for the flashes here and what effects they cause

  • depends on objects used

  • see also stroboscopic effect

  • single LED flash = stationary object

  • multiple LED flash = multiple interleaved stationary objects

    • not very distinguishable, maybe requires different LED colours or bigger object

  • single LED flash, then slowly changing flashpoint = stationary object that slowly moves

  • two LEDs flash, then slowly changing flashpoints, both in opposite directions = two stationary objects rotating against each other

    • looks very nice with time-based flashing

  • one LED at it's flashpoint on; after some time, switch off and second on, then off and third on, usw.

    • first long on-times for each LED; then shorter, then longer again
    • = multiple objects switching in and out, sometimes faster, sometimes slower

  • put an object on one side of the octahedron

    • = can we make that appear and disappear by using a single LED and switching flashpoints?
      • yes, looks very nice
    • works well with face put one two side (one smiling, one frowning)

  • face on one side

    • make it move by one LED, stationary with another
    • make object side without face stationary, then shortly blink over to face (shock), then off again
      • maybe at random intervals, so observers have to wait

  • other objects on one or more sides

    • can cause interleaving and spiralling effects

  • mount other objects on the motor

    • I would fancy a spiral
    • Try first with Küchenmaschiene
      • Looks nice with Kuechenmachine
      • Keep object motor running two: PWM can be used to change flashing speed until matches Kuechenmachine

  • softstart motor (start slow, then to target speed)

  • faces on two sides

    • one smiling, one sad
    • two leds, both faces smiling
    • from time to time, one flips to sad state
    • look nice!

  • now that lamps are restricted in where they can shine: Place one to highlight the upper, another to highlight the lower part of the object. Idea by Christ (works, try some more Oskar)

    • looks nice with both sides moving in opposite directions
