All in all it took me about 2 afternoons on a weekend and after a long break I can offer you finally a new instructable!
The work was split in 2 parts. First the assembly of the "electronics" = LED lights and on then creating the "Dragonfly".
Materials needed or rather stuff I used:
2 red LEDs
3 small batteries, I used type 312 with 1.2V and 160 mAh
1 2" long piece of 1/2" copper pipe
copper wire ~14/16 ga.
mesh or other material for the wings
Tools you should have and which will make completion of this project a lot easier -_^
Ruler / Tape measure
I might not have mentioned all and everything but it depends also how close you stay to my instructable and how far you want to go with your own.
Step 1: Assembling the "Electronics"
I did some calculating and everything should work out fine without the need of a resistor. I just assumed that I grabbed the average LED with ~3.1V and about 20mA, so 3 batteries with 1.2V each would add up to 3.6 which is not too much for the LEDs and according to the data sheet 1 battery should be good for 160mAh or about 4 hours continuous work, right? (I know I will hear from you if I got it wrong.)
The whole thing was done in less than an hour so I moved on to creating the body.
Please use this for your own creation: LED calculator
Step 2: Building the Dragonfly I
For the legs i cut two 5.5" and one 6.5" long pieces of 14 ga. wire and also one 4.5" piece for the tail.
Refer to the picture how i bent the legs dividing the wire in 4 equal parts!
Step 3: Building the Dragonfly II
Step 4: Soldering
Step 5: Attaching Tail and Wings
It happens that I had this nice wire mesh at home from other projects but of course you can use any other material. (e. g. I really liked the appearance of the wings MrSanchez made) With the help of a soldering iron I attached the mesh to the frame and cut it back with scissors.
Step 6: Installing the "Electronics"
Step 7: Tail and Eyes
Out of pure coincidence it happened that the big beads fitted perfectly over the 5mm LEDs I had used for the eyes. A drop of epoxy secured them safely there.
The same way I attached a pin to the dragonfly so that i could wear it to the concert.
Step 8: The Finished Dragonfly Pin
