Video Game Selector for AV cables

So you're gonna build a 25 position switch? 

lol, i wish!, i'd have 25 individual switches, in theory you'd only have to have them on the video lines, so that shouldn't be too hard,

also it'd probably be super wide, so id have to do some re-arranging of my stuff.

Well, in theory you don't need a switch at all.  I would probably just daisy chain a series of 25 inputs with and one output using diodes on the inputs so that signal doesn't find its way back to other consoles, which may or may not cause problems.  But, better safe than sorry.

That way you just flip on the console you want and it comes on without having to label 25 switches.  Just don't turn on 2 at the same time LOL!

ive never had any luck with anything other then connectors and switches, so id rather go with those.
currently im using a couple of boxes that use switches, so flipping a switch to select which console to use isnt a problem, however if you could do a little test with a couple of pictures, i might be persuaded to try it out.

I don't have materials on hand to make a sample and I'm not in a position to start something like that at the moment (even though I could really use one too), but I could draw a little diagram to better illustrate what I'm thinking of you'd like.

i think i understand what you mean, its just that if a project involves anything other than wire, switches or buttons then it tends not to work for me, but a diagram couldn't hurt, if you could make it as simple as possible too, that'd help!

at the moment im in the planning stages, in that i know roughly what id like to do and how id like to do it, if i can save a bit of money by not installing switches that'd be great!

of course, when i get the parts together i'll start a make thread...

(EDIT: ....and we've totally hijacked this guys thread!...)

But the SNES has a sliding power button, that's a moving part  

Check that beefy bastard out

This is what I was thinking for a super cheapo switchless switchbox.



No switches (obviously), just diodes to keep signal from traveling back to other, not-in-use consoles.  Like I said before, just don't switch two on at once.  Just make sure to put the diodes BEFORE each + junction so that turning two on at once won't allow one to feed into another.

I'm not sure that the diodes are all that necessary actually. But eh, it's not like they're going to be difficult to install or cost all that much.

I might build something like this.

[wiggy]

I don't know if they are a necessity either, but it does seem like a 'better safe than sorry' precaution to me

[Dr.Agon]

ok, first, thanks for the diagram wiggy, i see exactly what you mean now!,

second, what type of diode would i use?, the place where im going to get my parts from has 7 different types
