AI Thread Summary
To power a PC CD drive in a car, a DIY DC-DC converter is needed to convert 12V to +12V and +5V with two grounds. The user seeks circuit diagrams and parts lists due to the unavailability of affordable commercial options. Recommendations include using the car's 12V directly for the 12V supply and employing a 7805 linear regulator for the 5V output, as this approach is simpler and cleaner than building a full DC-DC converter. Clarification on the purpose of the CD drive is suggested to better assist with the project. Overall, the focus is on creating a cost-effective solution for powering the CD drive.

hello every one
i just joined up
can anyone supply me with circuit diagrams and parts lists
i want to run a pc cddrive in my car
so i want to make a dc dc converter thaht takes 12V and gives out +12V +5V and two grounds like in a pc
there are converters and inverters available
but they are expensive not readily available in our country and i can't buy online
so iwant to make my own circuit

can anyone please help :smile:

hello all
i still couldnot get help
may be some one could send me circuit diagram for dc ac inverter 100w or more
and parts list
thanks any body
 
You probably didn't get help because it isn't clear what you are trying to do. For what purpose do you want a cd-rom drive? Is it connected to a computer? Anyway, my recommendation would be to buy an adapter from Radio Shack that puts out 5V, rather than try to make one yourself.

You don't need 100W for a CDROM drive -- probably more like a couple of watts. Just use the car 12V straight for the 12V (maybe filter it a little), and use a 7805-type linear regulator to make the 5V. Pretty straightforward, and a lot cleaner supplies compared to using a DC-DC converter.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
