NeXuS: Shock it till ya know it; +375|6580|Atlanta, Georgia

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.
