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.
