Guitar Lamp Project

First of all I assembled the components for the lamp base.  The blue box is the base.  In the picture you can also see the12V DC input socket, fuse and switch.   The lamp power is obtained from a 12V power supply, similar to the ones used for Laptops.  The Green Neon wire can be seen with the Neon Power Supply.


I started by drilling the holes in the side of the box for the 12V DC socket, fuse and switch. 


Here I have just finished filing the hole square for the 12V DC socket

Here, you can see the 12V DC input, Fuse and Switch mounted on the box


This picture shows the wiring of the 12V DC input, Fuse and Switch.  Power comes into the box via the DC input socket.  The +12V line (Red Wire)  then goes through the switch to the fuse.  The other side of the fuse will be connected to the +12V of the circuit board,  which I will describe later.  The black wire is the 0V input.


Here you can see one piece of the guitar. this is the back panel.   It is made out of brushed Perspex.  You can see that I have drilled some holes.  I will be mounting some high intensity Light Emitting Diodes (LED's) in these.


This picture shows the LED's mounted in the Perspex.  The large LED's are 10mm, and the smaller ones are 5mm.  I chose colours of Blue, Red and Yellow.


Here, I used some copper tape.  You can see that I have soldered all the Cathodes (negative) of the LED's to the copper tape.


I have started to produce the circuit board, which I will be using to power the LED's.  12V from the Power Supply will be connected to the board.  If 12V is connected straight across an LED the current flowing through it will be too high.  The blue resistors which can be seen in the picture, limits the current through each LED to about 30mA, ensuring that the LED's operate at their optimal current level.  Each LED is connected to the larger green terminal block.


Here, you can see the completed circuit board, with the 12V supply wires connected to it.   The small green connector block on the left side of the board is for providing the Neon Power Supply board with 12V.  Each terminal (16 in total) on the larger connector blocks provides 30mA current for each LED.


A Picture showing the LED Circuit board on the right and the Neon Circuit board, both mounted inside the box. 


The Green Neon wire has been connected to the Neon Power Supply board, to ensure it works.

A picture taken in the dark, to get an idea of how the lamp will look.


The LED's have now been wired up.  Remember from earlier, the Cathode (negative) wire of each LED has been soldered to the copper tape.  A single black wire is soldered to the copper tape, this wire will be connected to the 0v terminal on the LED circuit board, in the box.  Using this method all the Cathode's are connected together.  A red wire has been soldered to each Anode (positive) of the LED's.  


You can see here that the red wires from the LED's have been connected to the connector block.


I've connected the 12v power supply to the box, and turned it on.  All the LED's are lighting up, so everything is ok so far.


This is the front panel of the lamp.  It will be mounted in front of the back panel.  The idea is that the LED's mounted on the back panel will shine through the front panel, giving off slightly diffused light.  Three LED's have been mounted on this panel inside the coloured disks to give an additional focus point.


Again, the cathodes of the LED's have been soldered together


Picture showing the wiring of the LED's.  I have chosen white wire this time for all the leads, so that it won't be visible through the front panel when the lamp is switched on.  The lead connected to the cathode has been marked with a black line, for connecting it to the LED circuit board later.


Another picture of the front panel, this time showing the Green Neon wire.  The wire has been threaded through a number of holes drilled in the panel, to make them look like guitar strings.


The front panel has now been attached to the back panel using a number of acrylic rods, as shown in this picture.  You can see one of the LED's in this picture.  When the lamp is turned on the LED will illuminate the front panel.


Cutting a slot out for the lamp.


Here is the completed slot.


To see what the completed project will look like I have temporarily mounted the lamp in the box.


I have attached the front & back panel to the lid of the lamp base using Hot Glue.

You can see here, the wiring of the LED's to the circuit board.  At this point I powered it up to make sure all the LED's were still working.


Here is the completed lamp.

Another Photo of the lamp taken in the dark, showing the illuminated LED's and the Neon wire.
