    I have two IR remote controlled PWM dimmers to control about 8 amps of 12v led strips. The two pwm dimmers are right next to each other and I can use the same remote to operate both. The issue I'm having is even though the photo transistors are about 2 inches apart, sometimes only one dimmer picks up the signal from my remote control.

    What I would like to do is solder an additional photo transistor (a spare one from another dimmer) with say about 4' leads in parallel with the other two phototransistors to ensure they both receive the signal from the remote. The reason for the 4' leads from my new phototransistor is so I can hide the dimmers out of site.

    My knowledge of electronics is beginner at best and I was hoping to find a simple low cost solution.

    I have a feeling it can't be that simple... :)
