The 15-20A as require for the ecco/tomar halogen bar lamp is required because they are for EMERGENCY use, they are more than likely illuminating in a burst that exceed the actual rating of the bulb extremely bright! I realize the above may be a lot to understand all at once, and it is apparent this thread is beginning to become a back and forth issue.Īdditionally, your claim concerning the high current pulses that destroy the filament is also subjective, the filament of a halogen is very rugged in comparison to the typical filament practically all filament lamps draw current, this is not uncommon.
Remember, the above time can EASILY be re-calculated and adjusted in the event the example time (250ms) is longer-shorter per bulb or all bulbs actively on with smear present on each bulb until the cycle repeats.Īgain the key word is "TIME" the halogen does not know it is smearing a flash, the only relative aspect is ON - Decay - OFF time! The above calculated time can also be outlined with the majority of halogen lamp bars using the rate of time as calculated above. Let us say the smear time will take 250ms to complete, the latter will leave the filament ON longer than a simple flash before proceeding to the next lamp etc.
Remember, decay/timing interval is the key word. Scroll to page four, the variety of programming methods can perform a similar concept as the knight rider. Obviously, you did not take the time to read the instructions concerning the 3055H.
#Knight rider scanner sound mp3 download series
But, an true Knight Rider scaner has 8 light and not 9 like this one, i think it should be ease to fix this project.īut Audioguru tell me something, to get this effect with led's, it could be done with 47uF or 100uF eletrolitic capacitors right? Connecting then in series to ground so the acumulated energy in the capacitor will discharge slowly and so the led will have a fade effect right?įor thouse that want to build the project i've included in this message the board and schematic. This circuit is not that all bad, comparing with this simple CD4017/NE555 (2CI's) this 7CI's project has a is very smooth movement as you can see in my video. Is THAT effect that i want to build and reproduce in a small proportion with led's. What catch the eyes is not that coming and going effect, but the impression that is a devil traped inside that scaner, you know, like an evil bull with red eyes impacient, looking at you, coming and going just waiting the right moment to get you. I've done long time ago the basic CD4017/NE555 with some power transistors and light bulbs (i said bulbs not bubs D ) used in brake light, and it work like you said, when the light shuts it fades slowly making a nice effect. Yep, i know that, but sometimes you have that feeling that "it might work out".
