I love 8-bit AVR but need more power!
And when the errata sheet from Luminary scares you (there's a nasty couple of errors) or their delivery dates get you tired (they still haven't released the µC I used that was...

Torrid Transformers - buck/boost?
You'll get something out of it - however, as ArnoldB says, it may not be quite the 220 V you want. If this is acceptable or will cause your equipment to fail... well, no one knows...

What's the purpose of the ground plane?
Naturally, the spiky CMOS current draw will pose the largest problem for the ground plane on PCB's, however I felt it more complicated to explain. With simple resistance and...

High Efficiency Regulator
If you really need 9V, you can always use 6 AA batteries and "tap out" the microcontroller after the bottom two or three (3V or 4.5V). Looking at where you're placing the device,...

What's the purpose of the ground plane?
Pouring ground on both bottom and top won't hurt, and it's (apparently) preferable from an EMC view, rather than pouring power on one side. Having power pour will create a nice...

Multithreading
And you don't even need an RTOS to really do it, to be honest. I don't know the exact CS definition of it, but I recently wrote a C program (but not for an AVR) that ran "bare...

Eagle Gerbers and Excellon Drill Plots?
They ought to - though I've only done it once, and can't for the life of me remember what the name of the program I used was. That's the downside to working through a fever and on...

Schematic and PCB review
Happy to help! Hope it works as intended. Otherwise, that's just a regular step in development: Iteration :)

Stuff 'flux' black or blue for PCB!
Uh, if you made it yourself, do you have a soldermask? In most cases, that's a "no". What I suppose you could do is once everything is assembled and tested and done, you can just...

Schematic and PCB review
Well, with the new design, I have only two additional comments: The ground connect pads would be better placed inside the ground fill, so they're more strongly attached. The usual...
