Is there any issue with this configuration?
Ok, if it's not a good option,how can i have 5v @ 200ma around 1USD?

Is there any issue with this configuration?
And i have read in some books before that we can make non-polar capacitors this way...bit unfortunately i don't recall the book.

I want to have a high voltage non-polar and cheap capacitor(around 3-4uf 400v). they will act like a resistor and they so I can use a secondary zener and low enough resistor to...

Cheap way of 16bit analog accuracy
Quote:But I'm still curious why 16 bits are needed? Because they say it's 16bit but the actual effective number of bit's are lower. For k20 series it's about 14.5Bit. And if you...

Guys what’s your opinion about Ref voltage Chip. I think ADR421 is a good candidate.

Because it needs an internal RTC, and Old AVR's do not have them, and recently I have seen cortex m0, they are achievable in 1usd in 1k qty. The parts can be anything, but no BGA...
