CD-Drive power Answered

Hi, i have a desktop cd rom drive 52x max, i want it to connect to my laptop using IDE to USB cable. I have the cable, I tried to connect it but it's not working i think it's because it needs more power. on cd rom drive its written

DC 5V -------------1 A
DC 12V -----------1.5A

I know i can buy the power cable, but this time i would like to do it myself with battries...

At the back of the cd rom drive it have 4pins for the power, but i don't know how to connect the battery with the pins? what voltage should i use? n which pins?

thanks

I wouldn't advise using batteries for this, a 52x CD-Drive will drain any battery pretty quickly. I'd use a wall-wart or 2 to get the desired voltages you want.

As for the pinout, http://pinouts.ru/Power/BigPower_pinout.shtml displays the pinout of the cable not the CD drive end.

. BTW, in that diagram, the two blacks (+12 V Ground and +5 V Ground) are also called -12V and -5V, respectively.

so, you are advising me to buy the already made one??

By all means it is possible to do with batteries, or a single battery if you're comfortable soldering a simple circuit together, but unless it is something as big as a small car battery or a motorcycle battery, you're not going to get a good deal of life out of it.

ok, what i need now is how to connect the power with the cd drive, can someone show me? thanks

The link that I gave you shows how to do that. You can buy the connector at Radioshack or any other electronic parts retailer. The pinout given shows the correct connections as if you were holding the plug in your hand, looking down one end of it.

ok, but isn't possible just to use + and _ cables and connect it directly with pins without buying anything? thanks

. Rob the connector off of a scrap computer power supply.

Yeah you can do that, just pretend that the plastic housing of the plug is there, maybe hot glue the wires together. You can then just solder them to the pins if you're willing to sacrifice the drive.

well, i took 12V from the adapter + and - then tried with all combinations but didn't work, do i need 4 lines? or will work with two? thanks
