Picture of Miss Betsy's Dragonfly Pin
For a concert I needed something fitting and matching my wardrobe. Inspired by articles from Kaivin and MrSanchez, I started working on my illuminated "Dragonfly pin".
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 switch

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 -_^

Pipe cutter
Soldering iron
Different glues
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"

Picture of Assembling the
I had the idea for this fashion accessory when i found a lighter with a little flashlight built in. The only important part was the battery holder for 3 button cells. I also found a couple of LEDs and a little switch in my "parts and pieces" drawer. Little wires are not hard to find anyway.
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.

I make jewellery and I tinker with electronics...why on earth has it never occured to me to combine the two!?!

Thanks for the inspiration :)

Thank you very much but I took my inspiration from other members of this great community just as much. o_O

I like it. Nice work MissBetsy. This would be a great project to do with a child. Plenty of hand operations they could do to help build it.

Absolutely! Maybe I should become a "hands on" instructables teacher ^_o
I can already imagine the kids singeing each other with the blow torch or using lasers for the eyes. (Just kidding!!!)

You flatter me, but thank you very much!
There should be at least another instructable follow in the next weeks. o_o
