Hi all! I've been lurking here for a while researching these amazing looking string blades and have decided to take a shot at it myself. I'm not the most electronics savvy, but I think I'm starting to get the hang of it and would love for someone to tell me if I'm on the right track. Firstly, this being my first string blade, I'm only looking for on/off functionality... no scrolling, no sound, no flash on clash. Just to have it turn on, not explode, and mesmerize moths for miles =] So here goes...
I'm looking at a pack of 100 LEDs on Amazon that are rated as "3.0~3.4V 20mA" so with, let's say, 50 of these wired in parallel I would need to calculate # of LEDs X current. 50x20mA = 1000mA. Okay now I'm thinking of the power packs. TCCS sells Li-ion packs that are 3.7V at the lowest... I'm guessing that these can't be used. Or am I wrong there? Next up would be the resistance. I can calculate the resistance needed and solder that in, but then the BuckPuck caught my eye. It's rated for 1000mA (yay!) but the minimum voltage input is 5V (aww). I'm guessing that's a bust too.
I'm really thinking that I'm missing something here, and my question is what that may be. I've been searching around, without much luck, on what is used to get this thing going and I'm coming up empty. Any help or shove in the right direction would be greatly appreciated!
