Hey Guys. Before I go into the advanced forums on the web where this simple electrical question would be laughed at and shunned, I wanted to post here in a more friendly environment. 
I've got myself an SNES which I have hooked up to an HDMI adapter/scaler. Amazingly, the scaler doesn't introduce any additional lag that I can notice so I'm happy sticking with it.
The only issues are that it automatically stretches the input signal to 16:9 without pillarboxing it, and the device is always on which creates additional heat that I'd like to avoid. (Plus, it means my autoswitcher can't detect when the SNES turned on).
The case in the scaler has some room so I'm thinking of adding in a little circuit that will only allow power into the adapter/scaler when it detects the 5V output from the SNES.
My question is, can this be done? I can easily tap into the SCART connector on the board and the DC input connector. Just wondering if the 5V line from the SNES is consistent enough so that the adapter doesn't turn off during gameplay. Also wondering if a type of circuit like this can be created from resistors/capacitors/diodes/etc. and not needing any type of IC in there.
