And I found a factory can produce my complex drilling glass panel today
That's great news for me~!

Yes I just wondered where the 500 x100uF went...
Oh and why anyone would spend $850 for 50 resistors😀
Other than that, it's nice. But I thought the point of DIY was to save money 🙂
I love design and DIY but save money not my goal
My goal is push design to the limits
and find out what level sound I can create through optimize physical structure and components quality.
This is my previous design work

Commercial headphone amplifiers have long surpassed the DIY department for value vs performance years ago.
Objective 2 is almost 10 years old, but is thrashed by any $100 amp these days from Topping / SMSL / JDS / Geshelli
This build is simply "no compromise", and absolutely stunning. The total man-hours gone into this must be huge.
Is that commercial? Very smart. Presumably not, as you said you design EV power circuits?
Haha~ Because my friend is Commercial photographer and he Interested in my machine so take the photo for me
As I said, Audio DIY just my hobby.
My full time job is LEV/EV battery PCB designer
I work in world biggest battery pack compony Simplo Co.,Ltd since 2001
SIMPLO TECHNOLOGY CO., LTD.
Just finish Porsche and Google design project last week.
I love this company because I learn so much here then I can doing so compact design you saw.
because Li-po battery very danger if any design mistake.

finding constant power too high problem. debugging
Look like the 5V isolated DC/DC power supply constant power too high

You're welcome
Just bought an automatic Battery tester yesterday
Then I can make the battery discharge curve at home to calibrate the right side 10 segment Battery level LED

Nah, for me its always been about getting exactly what I want. there are few things we build that would save much money. Actually the foil SMD resistors seemed like one of the more reasonable parts in the BOM to me ... 😛 the $2400 in mil tantalum bypass caps on the other hand and several hundred just on surface mount nuts ...
it's an amazing project. Very impressive. I love the symmetry. There are certainly areas I would do differently and given the same budget, but thats the point of DIY.
How long does a charge last? 3 months? 🙂
