Keyboard Circuit Sheet Lampshade

FeaturedContest Winner
I had a really old keyboard lying around that I planned to use to make a Keylendar.  Upon opening it up I noticed that the circuit sheets were a really pretty bluey/green colour.  I thought this would make a great lampshade. 

For the light source I used an LED puck light connected to a USB cable so that I can have it near my computer.  The light cast through the lampshade is not overly bright but it makes for nice mood lighting.

Step 1: Materials and tools

  • Old or unwanted keyboard
  • Light and power source ( I used an LED puck light connected to a USB cable)
  • Metal tin
  • Glue
  • Clear packing tape
  • Hole punch
  • Screwdriver

Step 2: Measure and cut the sheet

The keyboard circuit sheets can vary in appearance so unfortunately there is no way of knowing whether you circuit sheets will be as pretty as these.

  • Dismantle your keyboard and extract your circuit sheets. 
  • Roll the sheet into a cylindrical shape and fit into your base.
  • Mark where the sheet begins to overlap and cut off the excess

Step 4: Prepare light

For the light source I used a LED puck light powered by my computer through a USB cable. 
  • If you have never made a USB light before simply strip the end of the USB cable that is not connect to the computer. 
  • You will have four wires inside, ignore the white and green ones (you can just cut these off), the red is positive and the black is negative. 
  • Since the voltage from the cable is 5V and my puck light uses 3V a resistor is required.  Use http://ledcalc.com/ to assist you in finding the right resistor. 
  • Connect the positive (red) wire to the resistor and the resistor the the positive part on the light then the negative(black) to the negative. The light should now work.

Glue the light onto the base of the lamp.

Hey- if you still have your keyboard could you shoot over the model #? Thanks- Astroboy907
ChrysN (author)  astroboy9073 years ago
I no longer have it but I did take a picture of the model #, etc. The model number is SCORP104. I don't know if the rest of the info. is helpful.

Great idea: It's projects like this that make me glad I discovered this place.

You deserved the first prize.

I'd say fortune favors the prepared- this and your tea lights are really nice circuitry artwork. Thanks for sharing!
Amazing idea. Love it =)

Why can't I favorite this? It won't let me
ChrysN (author)  SG1Oniell3 years ago
Unfortunately a Pro membership is needed to favorite something.
You're kidding? When did that happen? I was able to favorite several others today, and have probably 300 favorites or so. Why did this happen?
ChrysN (author)  SG1Oniell3 years ago
Sorry, I must be mistaken then, it must just be a bug.
I was going to say it didn't seem right, plus I was able to favorite others after it. I think the issue is that the bar that contains the steps at the top is blocking the favorite option at the top of the page. I would love to favorite this, you did a really great job with it. Perhaps after the contest bar goes away it will be able to display the favorite function, untill then, great job mate.

This would also be pretty portable because if you have an iPod, you can plug the usb into where the iPod's usb would go and then plug that into the wall.

Fantástico!Es un buen ejemplo de como reciclar las cosas y lo pondré en práctica en mi escuela para enseñar a hacer a mis alumnos.
Muchas Gracias!!

Thank you!
I think you could also use those plastic containers that new CD stacks come in for the top and bottom.
ChrysN (author)  georgiapeach7733 years ago
Nice idea!
ramhardikar3 years ago
Good one!
Nice!
I'm thinking there must be a way to attach old CDs to use as the top and bottom. They would have a hole built in to vent the top and you could run the wire through the one on the bottom if you glue on some wood beads for feet.

If you know someone who does scrapbooking, jewelry, collage, or shadowbox art, they might have a use for your keys.
don't use wooden beads for the feet.... use the keyboard keys! :)
Excellent!
ChrysN (author)  georgiapeach7733 years ago
CDs are a great idea!

Just great! An excellent idea, simple, cheap and easy to do! I will check the colour of the circuit sheet of a keyboard i have in disuse in order to make this...
sharzz3 years ago
This is a lovely contemporary lamp. I will collect the materials and make one. Thanks for a clear instructable.

I think it's an awesome idea!! :-)
ChrysN (author)  M.C. Langer3 years ago
Thanks!
Great work Chrisy! :D

I also can't believe I wasn't subscribed! Well... it's apperantly called "following" now... So I'm following you now! (okay that sounds stalkery... :p)
ChrysN (author)  MichelMoermans3 years ago
Thanks. The term follow is going to take some getting use to.
Yeah it kinda looks facebook-e.. I thought we were going to try to avoid that... Also what the hell? I can log in via facebook now?!
Thats what I was thinking- why the hell would we want to log in with a facebook account!?!

Just came back from the thrift store with two tin can lids, a kids night light and an old keyboard. Currently waiting for paint to dry on the lids.
ChrysN (author)  stncilr3 years ago
Cool, feel free to post a picture here when your done.
stncilr ChrysN3 years ago
Here you go! Can anyone suggest a project that can reuse the keys from the keyboard? Check out more of my projects on my flickr account! (and you'll find this image properly rotated!)

Nice! Did you check out the keylendar (http://www.instructables.com/id/Keylendar/). That's what I did with my keys.
stncilr ChrysN3 years ago
Its a nifty project, but i have a feeling i would not end up using it.
Cool. I made an Atari Punk Console as well. It's not as good-looking as yours (probably because i circuit bent it into oblivion), but it's got a lot of cool features. And nice lamp. I'm planing on making one, but i doubt it'll look anywhere near as good as that.
It's really easy to do, im sure it'll look as good as mine!
This is such a cool idea! I use the keyboard keys on my cat beds a lot. The rest of the keyboard often ends up as a frame, but couldn't think of any way to use these guys... but i love how cool they look, so i keep them... wondering what to do.

No i don't have to wonder any more... you have opened up doors of possibilities, so cool!!
ChrysN (author)  AlpineButterfly3 years ago
Ah, your the one with the cat beds, those look amazing!
Thank you, that's sweet :-)

I got to do this!! Sweet!!!
astroboy9073 years ago
Sweet, looks like a great project. May be worthy of taking apart my apple keyboard. If not, a trip downtown should get me a $4 used keyboard

Clever idea.

To make to light more uniform you can put in linear light source. You will end up having same lighting effect throughout the lamp. Also the bottom and top can be made using black perspex.
Also using cable seal you can safely attach the cord to the lamp side. Otherwise just make a knot on the cable slide a washer through on it and the feed if through the lamp side from inside. You should have the washer between the knot and the lamp wall, and the distance length of the cord in (between the knot and the connections) should be longer than the distance between the connections and the lamp wall. If you ever pull on the cord you will not rip out your electrical connection to the light in the lamp.
ChrysN (author)  MechEngSk3 years ago
Thanks the final product could use a bit more polish, a linear light would definitely look better.

You must have seen this in "62 projects to make with a dead computer" by Randy Sarafan. He came up with the idea, but yours is nicer.
ChrysN (author)  tfrost19803 years ago
Really, I actually haven't read his book yet. I guess trying to win a (signed) copy of his book using something in it is a bit awkward.

If you have trouble with the LEDs, next time wire it so each one has it's own dropping resister.

The failure mode here might be that one of the LEDs would die early from taking more than it's fair share of the current. Then the remaining two would fail because suddenly they both have to take on the current from the blown diode.

Here's what I'd do starting from scratch:

Solution 0: 1 x 3 array uses 3 LEDs exactly
    +----|>|---/\/\/----+  R = 100 ohms
    +----|>|---/\/\/----+  R = 100 ohms
    +----|>|---/\/\/----+  R = 100 ohms

The wizard says: In solution 0:
  each 100 ohm resistor dissipates 40 mW
  the wizard thinks ¼W resistors are fine for your application
  together, all resistors dissipate 120 mW
  together, the diodes dissipate 198 mW              
  total power dissipated by the array is 318 mW      
  the array draws current of 60 mA from the source.


(via http://led.linear1.org/led.wiz )

 I used 3 LEDs, 3.3 volts per LED, 5 v. supply, and 20 mA current per each.

awesome! love it when people come up with new ideas to to do with keyboard circuit boards
Nice! I've been saving an old keyboard sheet, waiting for something to do with it...
oriololler3 years ago
Looks great.
caarntedd3 years ago
I think I'll make this.
mikeasaurus3 years ago
Looks great.
If you're not happy with the top, why not swap it with the bottom? Seems to have a cleaner look.
The keyboard pattern looks awesome!
ChrysN (author)  mikeasaurus3 years ago
Yah, I should do that, I guess I had my heart set on finding another lid.
