NIGHT RUNNER

I made this Night Runner circuit for my car and scooter.

At night it gives a very good effect and can also be used in the daytime.

I have a switch to switch it on whenever I want to.

 

In the Knight Runner circuit, the 555 is wired as an oscillator.

It can be adjusted to give the desired speed for the display through a 500k variable resistor.

The output of the 555 is directly connected to the input of an IC. CD 4017

Each output can deliver about 20mA but a LED should not be

connected to the output without a current-limiting resistor 330R in the circuit above. 

 

Using six 5mm LED’s, the display can be placed in the front of a car to give a very artistic effect.

I have reserved this step for a video which I have not yet been able to load to my Instructable.

Knight Runner? I think you mean Knight Rider.

YES- I deliberately changed the name to sound different.
Night Runner runs in the dark?

First thing i thought of was cylon

Hi.
This is a great instructable!
I would love to build a couple of these.
Can you please make the diagram a little larger or maybe add a parts list?

Nifty little circuit, I can see some ways to use this one!  Keep the circuit small and it will fit under the back of my bike seat, a great attention getter tail light for night rides.  A buddy here wants one made with slightly brighter LEDs for the end of his boat dock.  On a dark lake, the ripple of light will make finding his dock a cinch!  I'll build that one in April, and run it from a battery pack and recharge with a small solar cell array.

Fine project and a great Instructable!!!
