Introduction: LED Lamp With Test Tube

We will make a lamp with led`s inside the test tube. You can use the lamp in the room, desk or for ornament.

Step 1:

The materials are:
LEDS, Piece of Wood, Switch, Battery, Electric Cable, Liquid Silicone, Test Tubes.
First of all, the form is drawn in the wood piece. Different kinds of designs can be selected. (animals, geometric shapes, etc.)
Then, the form is cut.

Step 2:

Then, seven holes are made in the top of the wood piece and LEDs are put there.

Step 3:

After that, an electric circuit is made with the LED's legs. A battery and a switch are connected into the circuit.

Step 4:

Next, only if you want, the wood piece is painted, and an other piece of wood with the same form, is put on the circuit to hold the test tubes.

Step 5:

Finally, the tubes are filled with liquid silicone, and put on the plataform

Did you seal off the top of the test tube after putting the silicon in it?

looks awesome what brand silicone did you use. thanks

For the LED's and electronics, couldn't you use an inexpensive LED light strip?

Awesome! If any of you guys need a place to get cheap test tubes, I suggest www.indigo.com.

Which other liquid can be used if Liquid Silicone is not available...???

YOu can get clear silicon glue at home depot or lowes. It will a silicon caulking and you will either get the large size and you will need a caulking gun. You can also color/tint the silicon using acrylic paint.

Damn! I was thinking of doing the exact same thing, a test tube with blue water and an LED under it... guess you beat me to it... :)

Nice project! I was thinking of doing the same thing except I wanted to use ultraviolet LEDs to illuminate florescent ink. I was thinking of using red, green and blue highlighters as a source of florescent ink and dissolving them in mineral oil because it is non-conductive. But I like your idea of transparent glue even more because it's stronger and won't spill.

good idea ! if you use this color the proyect will be nice and more beautifull

the circuit digram is a bit fuzzy, do you have them in a series, parallel? and do you use any resistors?
