Introduction: Make Your Underwater Aquarium Light With Hot Glue!
Today We will be Making An Underwater Led Light With Hot Glue!!
Who Ever Thought we could use Hot Glue to Make a underwater Light?
It uses 6-3Watt Leds ,1 (100Ohm)Resistor [Not Necessary] , Only Half Hot Glue Stick !
I am Participating in Budget Contest too as It uses Minimal Parts to make a Thing which is useable in many types like BathTube ,Showers , Fountains ,Aquariums,Outdoor Garden Light and many more.
Step 1: Get the Parts & Tools
(1) 6--3Watt Led's
(2) Half/Full(doesn't Matters much) Hot Glue Stick
(3)100 Ohm Resistor
(4) A smooth & clean Surface [ i used back side of f2 pcb ]
(5) Wire (of your desired Length)
Tools:- (1) Soldering Iron
(3) General Purpose PCB
(4) Hot Glue Gun
(5) Mini Screw Driver
(6) Small Scissors
Step 2: Soldering First Led
First Take the General Purpose Pcb and Solder 1 Led End on it.
By doing this Leds will not move while making Shape
Step 3: Think of the Shape You Want
Think the shape you want. In my case i am making a Circle Type with 3-3 parallel Led's
[Note:- I am using a 12v Power supply , Therefore I am giving like 4 v to each of led which will trigger there max Brightness.]
Step 4: Soldering the Desired Shape
Solder the Desired Shape, the only reason to make a Circle is to make the next hot glueing work easier.
Step 5: Plucking the Light
Now we will Take our Screwdriver and pluck the light .
[By this i doesn't mean that breaking the joints]
By plucking the light i mean that the cooper traces on which light is solder , that should be detached from pcb. Therefore it could be easily done by bending light up with screwdriver.
Step 6: Adding the Resistor Parallel
This Resistor doesn't Actually Do anything as it is installed in parallel and is just for supporting melted glue [In Step 8].
Step 7: Attaching the Wire
It is Obvious That we will use an insulated Wire . For this. [Be Very Sure that there are no cracks in insulation]
Step 8: Insulating the Full Light
In this Step the only work left has to be done by the hot glue gun.
1) Start by placing a huge dot in middle of any smooth surface [ Wait a little bit and dot should start making a circle]
2) make sure that the hot glue circle made is atleast 2mm thick and exactly of the light size.
3) Now, Put the Light on cooled Circle ( which would become the base of light)
4) Again , put a large sum of Hot Glue on Top of it and make sure all electrical path ways are covered.
5) immediately put it into a freezer and let it cool down.
Step 9: Again Plucking the Light
Again pluck the light by our mighty :p Screwdriver from one end.
No problem if it is not a perfect circle as we will cut the edges to make it a perfect circle.
Step 10: Make It a Perfect Circle
Now take your Scissors and cut the edges to make it a perfect circle.
Step 11: Test It!
Now take an 12v Led Strip Adapter and hook it with the light! And dip it in the water
And Here we Go ! We have made our own underwater light ! Only for 2-3 dollars!
