Introduction: NIGHT RUNNER

Picture of 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.

Step 3: Step-3

The assembled Night Runner circuit is shown in this photograph.

For easy assembly first fix the bases of the IC 555 and IC 4017 to the box and mark the legs as 1,2,3,4,5,6,7,8 and so on, so that you will not get confused while soldering the connections to it.

Step 4: Step-4

Follow the circuit and assemble the Night Runner.

Take care to maintain polarity.

 

NOTE no connections are given to leg 5 of the IC.555.

NOTE no connections are given to leg 12 of the IC 4017.

Step 5: Step-5

In this step assemble the POWER Supply.

This is needed to reduce the voltage of the car Battery from 12 volts to 6 volts.

The NIGHT RUNNER runs on 6 volts.

This unit can be placed inside or outside the box.

I have used a mono Audio Plug to connect it to the car power supply.

The female part of the plug is fixed in the car so that I can plug in any unit to

the car power supply when needed.

This is very useful, as you will experience in the future.

Step 6: Step-6

In this step check all the wires for continuity and then fix the IC’s to the base.

Plug in and ENJOY.

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?

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!!!
