Good to see you back - electrical engineering is tough. Wish I had the time to devote.. i was going to ask you for design help but it seems your time is accounted for like mine lol.
Ambitious project. But it's not an elegant design. Car amp has a DC to DC boost converter in it already. You're going from 240V ac to 12V DC to +-120V DC. It makes sense to modify the amp and eliminate a step in your design. Going from 240V ac to +-120V DC would achieve the power goal with A lot less current
@@seraphin_creates I'm not an electrical engineer. I'm just an electrician. I was fiddling with audio amps and electronics when I was younger. I built some simple amplifiers, but I don't consider myself an expert. My claim is based on simple logic. Why would you deal with a shitloads of current if you don't have to?
@@tiitsaul9036I completely agree about your point and that sounds like some credible experience to me too. Maybe this is more about finishing something that has opened up some interesting paths ..
The reason I ended up doing this is for several reasons, I might go into more detail in a future video But basically, creating a switchmode 240v AC to +/- 120v DC supply seemed about the same effort as +14v DC, and I wasn't comfortable modifying the amp (at the start of the project) This power supply should power any 12v appliance or charge a 12v battery without any modification to the appliance, so I can run multiple amps off the single unit This unit should be powerful enough to start any car without a battery, and I might be able to weld with it at the same time lmao I'd also like the ability to supplement my car's charging system to run a big sound system, as small Japanese cars which tend to be what I own have next to no space for alternators Also having a regulated supply means I can do things like amp dynos with fixed variables, and making the supply myself means I can probe voltages at the amp itself and have it correct for that ignoring power cable resistance
Make sure you patent any ideas you design. You should design a new type of car amplifier like the Brazilian. Design new types of transformers as well.. you have 2 hears..starting now.

Going to college to help build stuff for a hobby is so real haha. Respect man I hope this thing turns out good!
Its good to see more of the Dak.
Dakie!! Happy to see you blessing the RUclipss again 🥳

Good to hear from you! Hope you finish the PSU soon, would love to see the results
See you in 2 and a half years. Just make the power supply from yellow cake uranium and pig iron
Right! I thought they jabbed poor old Dak one too many times!😂😂😂 Greatful that he's alright.
Knowledge is priceless good to see you
Does the "ten tens" woofer play now, or is the Projekt on ice?😢
Brother Please reply
4th order bandpass
versus
6th order bandpass
Which is better?
I want smooth and panchi bass
Ambitious project.

What experience do you have to make that claim

This power supply should power any 12v appliance or charge a 12v battery without any modification to the appliance, so I can run multiple amps off the single unit
This unit should be powerful enough to start any car without a battery, and I might be able to weld with it at the same time lmao
I'd also like the ability to supplement my car's charging system to run a big sound system, as small Japanese cars which tend to be what I own have next to no space for alternators

@@Dakoustics I could see why a powerful 12v power supply would be useful.
Designing and building one is way above my skill level. Good luck.
Your my help me please provide schematics real time spectrum analyzer audio 20hz to 20khz total 31 band
Make sure you patent any ideas you design. You should design a new type of car amplifier like the Brazilian. Design new types of transformers as well.. you have 2 hears..starting now.
Don't show your schematics too
Counselor, you are mansplaining, lol,..just kidding
