Introduction: Desktop LED Lighting
A while ago i got a new (old) computer. The old computer wasn't working anymore so i totally fixed it.
I replaced the motherboard, the graphics card, the power supply and putted some extra's in. (Like an extra CD/DVD player/writer and a built in card reader.
I got all the parts from other broken computers. (Luckily it was not the same part that was broken in all the computers.)
So i booted the new desktop PC and...IT WORKED. YEAH!!! :D
So now the only thing that was missing was a LED strip.
I wanted to make that old looking desktop looking a bit more groovy.
Want to install a LED strip yourself? Read this instructable.
It's actually a piece of cake. :p
Step 1: Gather Your Materials
A LED strip I got mine from an auction on eBay so i got it pretty cheap (around $3/5m). If you keep an eye on the auctions you can get a LED strip really cheap.
Electrical wire: i used 2,5mm². If you have a LED strip this short you can also connect it with 1mm² but certainly not less. Because of the Amps running trough the wire. It's not that much amps but 1mm² is also not
Solder: if you don't have this, AliExpress sells it freaky cheap. (And with a good quality, i tried it)
Double-sided tape: (the LED strip doesn't stick well)
Step 2: Search 'n Measure
Search 2 wires coming from the power supply delivering 12V but are not in use.
In my desktop the 12V was delivered by a Yellow wire and the GND was a black wire.
If they are connected to a connector, cut it off.
Be sure you have a +12V and a GND wire.
Measure the distances for your LED strip.
You have 2 options for straight corners: bend or cut.
If you bend the LED strip you do not have to solder the LED strip.
If you cut it you have to solder the 2 pieces to each other. Harder to do but only option if you don't have a straight corner.
If have to cut the LED strip be sure you cut it in the middle of the solder pads.
Step 3: Cut, Solder and Stick.
Before you cut the LED strip mark every + and - on the solder pads.
Now cut the LED strip to the measured lenght.
Cut the electrical wire to the measured lenght.
Solder the LED strips to each other with the electrical wire. + to +, - to - !
Solder a piece of electrical wire at the beginning of the LED strip for the power.
When ready stick the double-sided tape on the LED strip.
Take of the sheet of the double-sided tape. Do this piece per piece.
Take of the sheet of piece 1. Stick it on the inside of the computer and only then take of the second sheet and so go on.
Step 4: The Switch (optional) + Power Supply
In this step we install a switch for the LED strip.
If you don't want this you don't have to install it.
You can connect you LED strip directly to the power wires. This way the LED strip will powers up together with the computer.
First search a good place to install it. Somewhere where it looks nice.
Make sure you can drill a hole in where you chose to place it.
There better be no wires running behind that place.
Take off the front panel of your PC and drill a hole which is equal in size as the switch shaft.
Put the switch in and tighten the screws.
Solder the + wire from the LED strip to the switch.
Solder the +12V wire from the power supply to the switch.
If this wire is not long enough you can solder a piece of electrical wire to it but don't forget to put a piece of heat shrink tube on it.
Solder the - wire from the LED strip directly to the GND wire from the power supply.
Don't forget to put heat shrinking tube on the wires!
Step 5: Done!!
Thats's it! Simple isn't it?! Now you have a much nicer desktop.
We have a be nice policy.
