Hello, I have tried to make of countdown with many 1N4148 and CD4017. But first led has weak licht and at last led has much light. See animated gifs. So I will make to get this. Like as this but there is more. (above the voicebox are 4 leds) And cruise leds controls will last on.

I have thinking about this. I will made from 10A into 5A. 10A is too much for my projects.

LOL......... ;D

Nothing ;D I did not use when I drive.

I have already break lights up (all-on) then knight rider effect. My Power Supply are to weak to get break light up. So, you see this effect when I try get break light up then knight rider effect. http://www.captain-nguyen.nl/knightrider/videos/NewScanner20Watt.wmv

Schematic works ;D 8)

I understand, Thank you.

MJ15004 use 250W. :-X Have not looking to datasheet. Datasheet MJ15004 Is this schematic right now?

I have found this schematic from internet. But I have adapt from 2A to 10A power supply. Could this work?

Long time ago yes. But with 1K resistor will it quicly turn of?, and without? Slow to off?

Hmmm with LDR? Why not from lights?

He say: With LM3914 work much better than LM3915. I think you read the level better with LM3914 than LM3915.

I have got only 10 LED air/fuel gauge version, with LM7805 As you would like get circuit diagram here is it.

I use with PIC16F628. But I must learn how write pwm effect in Jal.

Thanks for info. And it work now with tip32. I did not use always. Only for show at meeting or friends.

Okay, I will use 1 W resistor.

Thank you, And resistor of 27 ohm. Is it 1/4 watt or 1/2 watt?

Like as this? Or must I replace from Tip41 to Tip32?

oh, I have wrong. It's Tip42, not Tip32. ::) And it's for car. With relay hear you all the time when it on. :o It would not like it. And this schematic from http://ratliff7.tripod.com/counsel.htm would not work best. I have hear from other forum. They say it does not work best, It would very heat. So, how dit they do that? Like as Knight-f2k4 scanner. And could this work at first schematic? http://www.electronics-lab.com/forum/index.php?topic=2373.0

Hi, I'm new here, and come from holland. I have one problem. I have made my Knight Rider Scanner with PIC16F628. Only LED will work, but no halogenbulb. I have tried with this schematic.
