Hello,
My old PSU quit on me. I've decided, rather than fixing it - I'd like to design a new one. Here is what I'm looking to do:
- I want to keep the original carbon fiber case I built for the old board. It has 5 switches and LEDs so I would need it to stay that way, unfortunately (but what are you gonna do about it).
- I need it to have 3.5v,5v,9,12v,15v, and 24v. It must fit in a 2.5" by 7" area with 4 inches of height.
- The original broke down with less than 300ma of draw. I'm hoping the new PSU could be at least 2a.
- I have quite a few random parts just laying around in my storage unit. I see a lot of schematics that use the lm317 as the voltage regulator but the datasheet says it's only good up to 1.5a. I have a few of these so can I use 2 of them to get the current up or is there a better solution? I also have a bunch of transformers from small to pretty big. But most of them have no writing at all on them.
How would I find the primary and secondary coils in them and find out what the voltages, ampere of them are? So this is where I'm at with my project. I'd like to stay at a beginner skill level. So anyone who is a good teacher over forum chat would be helpful, but I'm open to all ideas.
