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.

Part list.

No PCB required but if you can make one then it’s very good.

To make the matter short all the Parts are mentioned on the Circuit Diagram.

You can assemble the circuit in a cardboard box or make a box out of flex board.

A plastic pencil box will be ideal.

The LED’s may be fixed with a spacing of say 1” to ¾” apart.

Use Hard disk or floppy disk discarded cables for wiring the project.

Nice work, but what the use??
Knight Runner? I think you mean Knight Rider.
YES- I deliberately changed the name to sound different.
Night Runner runs in the dark?

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?
