I'm not trying to beat my chest and show how much I
know. My desire is to bring solutions, not just criticism.
By fixing a specific part of a problem, one can not
assume approval of the whole, that would be remiss let alone
foolish.
I was addressing specific criticism of a specific
design fault . . . . only.

You are a smart guy.
You can see the deficiencies in a design and correct them on the fly
(npi), but not all builders have that capability. The problem with the LED
power is more a symptom than the problem. It shows and incomplete
understanding of the factors that go into a reliable design. There are a
multitude of things wrong with the proposed design and the average builder
should be aware of these things in the interest of safety. Hamid pointed
out a few of the most egregious problems. The full list is much
longer.
You would not build a device unless you plan to use it. If
you use it you will come to rely on it. If you rely on it and it fails you
will likely be in a worse (perhaps much worse) state than if you did not
have the device in the first place.
This reasoning is why you want
to avoid poorly designed and or poorly tested devices that may effect
flight.
FYI, Hamid has been designing electronics for decades and
certified avionics for 12 years. His designs range from simple
communication repeaters to complete, certified Pentium motherboards.
His products are used by the likes of Cobham, Boeing, CMC Electronics,
Rockwell Collins, Honeywell, Liquid Robotics, and on and on. He is wise
enough to know that putting a Band-Aid on a massive blunt force head
trauma will not fix the big picture. Likewise, offering a patch for the
LED problem would be, de facto, approving of the balance of the design.
Do you think the balance if the design is reliable, fail-safe and
unlikely to negatively effect flight? Consider your answer carefully as it
will say a lot about your design skills.
