I have completed my initial hardware debugging of v0.1.1, as  reminder - key changes were: Moved from switching 5V / lin 3.3v regulator to...

I have been using the Arduino programming environment for this project to take advantage of its rather simple and integrated approach.  It a...

Almost all boot-strap FET drivers rely on a less then 100% duty cycle in order to drive the charge-pump; actually have found only ONE  excep...

I have not done too much on this Regulator project as of late, as we have been busy with visitors and visiting too many coffee shops.  But I...

This morning I posted up a parts list and Mouser BOM  (See Parts list tab above).   And there is some good news / bad news from a cost stand...

I looked at what was needed to move the Arduino 'cpu' from 5v to 3.3v, and it looks doable.  the CPU certainly support 3.3v, a bit a...

Today I posted a revised version of the regulators schematic, and also completed filling in the Hardware Overview.  Some major changes betwe...
