Thread: Require help on alternative parts for power supply

This is the exact diagram I used for mine. Got all parts from Farnell, who can be contacted on this link in Oz.

Are you sure all items were to the same value. Don't suppose you have your receipt handy with the product codes, it would make ordering much easier!

Thanks

Odin

This is the order list. Ignore the quantities shown, as their web site was a bit screwed up (I didnt order 200 caps!).

Dont just order everything on my list, as some of it was used for other stuff I was building, but most of the part numbers are in there somewhere (left column), just key em in and see whats available. THe discontinued parts should be duplicated with their newer alternitive lower down the order I think, it was quite a while ago.

You are a life saver!!!!

Thankyou so much you have no idea how much I appreciate it. Do you have any details of your player on the web, I would be interested in knowing how your player and powere supply have performed through time. Where are you from, Aus or somewhere else!

Anyway, I realy appreciate it!!!

No web page yet as still building (third revision, never been installed in car, but works good on bench with car battery). Will post it on web site when im happy with it! BTW from UK.

While I have you here, are there any tips you have for me before I build the PSU?

How long did it take to receive your parts once delivered?
Do you have an email address so I can ask questions once I receive the items or would you prefer to go via here?

Thanks

Odin

Got the parts next day delivery, so no complaints there.

Not much in the way of tips except take it slow, and dont forget you will need a few hours to build it, and something to build it on (like breadboard). It took me the best part of a day to do it properly. If you have any probs just port here as there are a lot of people with more experience of building these than me.

Buy some heatsinks while your there. Those regs get really hot, especially the 12v one, I think mine would fry in seconds if it wasnt sinked. Trust me, its easy to buy em than worry about it afterwards.

Has anyone got a PCB design for the power supply. I know everyone refers to the Sproggy PCB but this power supply has different components, so is there somthing Im mis-understanding? Because having different components means re-designing a whole new board, right?

Thanks.
