Title: Light Bulb instead of 100 ohm 3 W resistor on SS hub
Post by: Night Owl on February 14, 2012,

Was there some discussion about using a light bulb instead of the 100 ohm resistor in the hub?  I tried searching for it, but couldn't find it (try and search for "resistor," "light" or "bulb" on this site  ;D)  I was thinking about building a bench power supply out of an computer power supply and I've seen a ton of recommendation (resistor, automotive bulb, CD drive) and I thought I saw something similar here.  Or maybe I imagined it.

The problem with using a light bulb is that they do burn out and in many cases they fail on startup.  This could throw off the regulation in some supplies and could possibly cause damage.

on my board,   I using the NTE Electronics 5W110 100 Ohm - 5W - 5% Resistor as it fit right in place..
