LED dimmer or potentiometer?
I have like 50 or so red leds i need to be able to dim, I found a “led dimmer” on ebay. Its pretty straight forward, but its 10 bucks. I dont want to pay 10 bucks per dimmer in the future. why not fabricate my own?

there is the dimmer. Or should i just make my own out of this http://cgi.ebay.com/3296-Variable-Resistor-Precision-10-pcs_W0QQitemZ260572573776QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3cab55f050#ht_2610wt_1165
Any links to cheap potentiometer/Variable Resistors or build instructions or what have you would be much appreciated. thank you.
The one you reference is made for high power LEDs, 100 watts. And it has few specs other than the Input Voltage and current specs, so there is no way to tell if it would work for your application.
The second reference is a bunch of 1/4 watt pots, not nearly enough power for your application.
You need to supply more info, voltage and current of the LEDs, and your power supply voltage and current. Do you need to control then all together or individually?
