Simple + small heartbeat LED
If it's the only thing the micro needs to do, then this will probably work. If it needs to do other stuff, put the logic in the timer overflow interrupt instead. int main...

What exactly is PCB electrical testing?
sum(n, 1, N) = (N^2+N)/2 so yeah, it's about half. But since we're talking complexity, constants are usually disregarded.

Reliable 3.3V & 5V Regulator
These have even fewer components, but aren't exactly cheap: http://www.intersil.com/powermod...

Reliable 3.3V & 5V Regulator
Syncronous bucks have a second FET instead of the diode, which is usually integrated, such as this one: http://focus.ti.com/lit/ds/symli...

3.3V LDO (TS2940) Dropping to 2.1V with WIZ610WI Device
Either find a way to cool your regulator, or ditch it. Use a linear regulator that uses pcb copper as a heatsink. Connect these to the ground plane, for a lot better heat...

Moving away from arduino pseudo c to real avr c
F_CPU is defined in the project options, redefining it is a big no-no. Go to the project options and set it there instead. For single file projects, sure it works. but once you go...

Why two !! in !!(val & (1 << i))
Yeah, I used to make statements like that. Once I had to maintain my own code, I cursed myself for doing so, because it took so much longer to figure out what i was thinking when...
