[simpits-tech] How to hook up fans & lights??

[Rod Dale]

I use old power supplies out of 386 or 486 PCs (remember them ?).These are 
continuous DC output - load or no load !!! I use the 5 volt output to power 
the backlit panels ( the real ones). I'm still looking at a method of 
dimming these, at the moment they are on or off.
For flood lights and such I'm using 12 volt lamps powered from a bench 
power supply. For dimming I'm using those small kits you can buy for 
controlling 12 volt motors etc. These can carry up to 10 amps, which I've 
found is more than enough.
I'm looking for a similar item for the 5 volt backlighting, any ideas ?
