    Hey all!

    Just found out an awesome tip! Its always such a mission rigging up an adapter for PC fans to cool your tank - but I just read online that some cellphone chargers run at 12v (but check on yours before you give it the chop)!

    So, if you want to rig up any 12v electronics, it should be simple matter of finding an old cellphone charger (i'm sure everyone has a few of these lying around), chopping the end of and splicing the two wires!

    Will try this out this evening hopefully. Will be chuffed if it works! LED's also need a 12v supply, so would be a breeze to rig up a DIY moonlight rig too! :-D


    Like so;

    Also, if you can't find a 12v charger (even 6/7v should still work), you can "double up",

    Also to take into consideration the current you want to draw from these old transformers ... voltage isn't everything ...the last thing you need is the house burning down because you overloaded these wound transformers!

    Very good advise Chika!

    As for cell chagers being 12V, Not sure where you read this, as most (99%) chargers have a output of only 5 Volt! (unless from 1980/90's perhaps)

    Yeah, you're right lighty - that I got from the first post I came across. I see now that most are actually 5v, but that most PC fans will still run at this voltage.
