I bought this kit.

http://www.amazon.com/gp/product/B0060F … 00_s00_i00

I use this calculator

http://ledcalculator.net/

My kit came with 1/4-watt 200 ohm resistors.



The calculator says to use 91 ohm 1/8 watt resistors. But all I have are the 1/2 watt 200ohm resistors. Can I use them or will something explose in my face?

why not just buy them

in all seriousness just find the max current and voltage the LEDs support and use a multimeter to find out if you're over or under

Random projects.

Like random stuff you would see on instructables. The power source would come from 9v batteries and/or old cell phone wall chargers with appropriate voltages according to the calculator.

well logic says that if they resist more at higher wattage you wont hurt your LED's, they'll just be incredibly dull or won't light up at all

It worked just fine actually. Science prevailed. Worthless thread is now worthless.
