Hi,
It's been many years since I've done any electrical engineering work ( used to in high school, doing radio ham stuff etc). But for halloween this year I decided to add some lights onto my outfit, "no big deal" thought I , a few led's, how hard can it be......
So after buying 40 - odd nice red led's and beginning to assemble them, I realised that my original design would require a huge number of batteries to power it !
In essence, I have 2 circuits, one for the wings, and one for the mask.
The led's in question require 1.7v and 3000mA ( I need to confirm the amperage )
The wings have 24 leds in series , and the mask has 10 in series. This would require around 7 9v batteries !
Since this seems a little excessive I did a bit of a google and discovered the 'voltage booster circuit', but I'm afraid it's a little over my head, I'm not sure I even understand the theory, let alone how to choose the components ( for fear of setting myself on fire). I'd really love to do this 'right', and after a few hours of searching for a solution I discovered this forum, and thought I'd at least ask. Push comes to shove I'll carry around a pile of batteries, but I hoped that someone here might find it an interesting challenge, or already know a solution and be able to help me out.
Thanks ^.^
