Thread: Guh, made a mistake... Any advice?

  1. #1

    Default Guh, made a mistake... Any advice?

    So the electronics for my saber arrived today. And I forgot to order a 5w resistor... I have plenty of 1/4 watt resistors on my desk, but I calculate that I need a 2.2ohm 2W resistor... so that 1/4W probably won't cut it huh?

    So anyway the hilt parts of my order haven't shipped yet, do you think I should add in a couple of the 5w resistors, or try to make due with the 1/4w resistors I've got?
    I don't want to be one with the force... I would rather have control over the force. Does this make me inherently evil? I don't think it does.

    I am always of the theory right tool right job, never wrong tool right job. Taking chances can cause issues that are not cheap. However I am not electronic specialist.

    The 1/4 watt resistor will get hot, let the smoke out, and then likely allow your LED to do the same. All in a couple of seconds, depending on power source.

    Get the correct resistor. You can always use a higher wattage resistor, but you never go lower.
    We all have to start somewhere. The journey is all the more impressive by our humble beginnings.

    Exactly!

    Lol well thats cool because I picked up a "Magic Blue Smoke Refil Pack" from Sparkfun.com last April 1st =)
