Re: How can I build a variable speed controller for a slot c

stevo
If you have 2 transformers, run one to each lane(better that way so you dont get the spikes when one car comes off) an put the ghost car transformer on a light dimmer used in houses

Re: 15 volts from a pc p/s???

only mod i did, was instead of using 2 10ohm resistor blocks on the 5v wires for load(couldnt get 12v using them) I am using 10 1157 automotive bulbs in series for my load, they draw 13 amps!!!!! but i get 12v on the nose sometimes 11.99v

Re: 15 volts from a pc p/s???

ok i found out in testing that if i use the +3.3v an the -12v i get 15 volts, using the +12v an the -12v gives me 24 volts i can get anywhere from 3.3-24 volts out of this by using the -12v an -5v as the ground an the + side for possitive :)

15 volts from a pc p/s???

How could you get 15 volts from a pc p/s<p>I know doing this with batteries you just add them in series to the volts you want, but how would you do it with a p/s with a 12v an 3.3v out leads??connecting the 3.3v an 12v together??<p>Thanks
