On this instructable I will show you how to make a really cool spinning rainbow light wheel!

This is my entry into 'LET IT GLOW' contest.

I made this spinning rainbow light wheel from what ever the parts I have sitting in my shed. This project is a bit difficult to build, but the part are easy to get, I brought some part from the electronic store a while ago and I reused some parts.

This project not that expensive to build, it really depends if you reused parts or buy new parts. This project cost me about less than £10.

The spinning rainbow light wheel can be used in stores, business , parties, disco or advertisement to grab people's attention, or it can just be used for fun.

Please note that I am only 15 years old and I am not very good at grammar so if you find some parts of the instructable confusing, please let me know and I will try fix it.

Please beware this instructable involves building a high-speed device which can harm people if they touch this device during operation so I am NOT responsible if anybody gets injured by this device.

Ooh, just look at that beautiful rainbow... More great pictures on step 10!!

The parts you will need...
  • Super bright red LED
  • Super bright orange LED
  • Super bright yellow LED
  • Super bright green LED
  • Super bright blue LED
  • 7 1K resistors
  • Solder (I used lead-free type)

  • Aluminum tape
  • lots of wires
  • Thin flexible wire
  • VHS cassette that you don't mind destroying
  • Masking tape
  • 6v power supply

This is all optional parts if you want a flashing spinning light wheel...
  • 555 timer IC chip
  • 4.7uF (or similar) capacitor
  • 4.7K resistor
  • 10K potentiometer
  • 3 2N5551 NPN transistors or similar

The tools you will/may need...
  • Temperature controlled soldering iron/gun
  • Wire stripper
  • Wire cutter
  • Hot glue gun
  • Long-nosed pliers
  • screwdrivers
  • a tool for cutting veroboard into pieces (I use dremel)

The abilities you need are...
  • Good using soldering iron/gun.
  • Read schematics.

now to put it on a fan
thats what i was thinking !

Rainbow Dash would approve!
If I had the parts to build one, it would make my room 20% cooler. To Plasmana: Really cool project, I just wouldn't have the patience to build one.

could u be plz be clearer on where the wires from the centre of the spool go???this part s a bit difficult to understand.......

this is one of the parts that i get lost in can you go over it with more detail?

Very good job on the descriptive step by step instructions Plasmana.  I found it easy to follow in some areas but hard in others. 

Is the aluminum foil all negatively charged? 

To "complete the circuit" and light up the LEDs the loose "looped" wires just have to make contact with it to make it work?

Why were you trying to make two separate rings (I am wondering about the thought process)?

Very good idea.  You should check into "brush" motors and how they made electric motors work when they were first invented.  The "loop" and "washer" idea is not that bad!  Better friction loss than what I was thinking of doing for my own project.

Cool !
But i think not perfact.
you can search about anvii.
they are true rainbow wheel light.

Awesome!

COOL!!! I like LEDs and everything that has to do whit them. Good idea! The circuit whit the 555 timer could be simpler. rate:***** +vote
Plasmana (author)  comodore6 years ago
Thank you for the ratings and the vote. :-)
Hey  man, very nice instructable , but I have a question. How does the NE555 timer works? I mean how can you set it to do different programs like generating impulses each second for a minute, then one impulse each 1 ms for a minute?
Thanks for the answer.
How does the aluminum tape conduct anything? doesnt the adhesive block the electricity?

itx great.....!!

but can yew tell meh the formation of pulsating dc using 555 timer ic??

You can get the same kind of effect with a cheap 1-dollar LED spinning top. I did several photographs with this stuff several years ago. Results were quite interesting but lacked that DIY building experimental mood.

thats awesome!
Plasmana (author)  Rainbow_Han5 years ago
Thanks!

the problem with this is if you put the battery on the spinny part, the wires to the motor will twist up. if you put it on the bottom, th led wires will spin together...
no it has contacts that touch the spinny part.
I remember as a young kid, my dad an I would break open old VHS tapes and make spider web like constructions in the house by tying one end of the tape to something and running around with the spool.
Plasmana (author)  FreshPineSent5 years ago
That is cool!
Sweet, i used to do that, but the fact that YOUR DAD did it is awesome!

You mention large washers for contact. I have a suggestion ... try plates from a dead hard drive. Actually, from a hard drive you could get the motor, the plates, some cool aluminum washers, and some movable contacts that could make your project simpler and flashier. Very good design, and clear instructions. Keep up the good work
Plasmana (author)  bmpa6 years ago
I never thought of using dead hard drive for contact, thank you, I will use dead hard drives when I get one (I don't have any at the moment). Also I am glad that you like it.
BUT you will need a stepper driver for the hard drive motor. :) not sure but i think Jaycar has some driver kits. Very nice instructable. Very easy to follow.
Plasmana (author)  wierd idiot5 years ago
Yeah, probably, I'll think of something else... Thanks!
Glad i could help. :)

Great work on aligning the LEDs. That works really well.
puffyfluff6 years ago
This is really cool.
oddblob6 years ago
cool would it not have been easier to power the l.e.ds from a few button cells on the spinning spool itself, rather than use the contacts? ingenious solution though...
Plasmana (author)  oddblob6 years ago
Yes, I could have done that but I don't have any button cell batteries though.
AWESOME JOB! I really want to try this out. It's very easy to understand like Brennn10 said, but looks a little hard, kind of. Nice job! (added to favorites)

I am glad that you like it and find it easy to understand GorillazMiko.

Awesome. This is very similar to the instructable I posted for the Get the LED Out challenge. This one is a lot better thouh. Fantastic job.
Plasmana (author)  MdP16326 years ago
Can you show me your instructable? I like to see it.
