I appreciate the non-requested recommendation, and yes.

Fair enough, I guess I will add in those capacitors for the LR. I was trying to cut cost, but whats $0.50 really? As far as the caps for the ICs, what size do you recommend? How would I calculate such a thing?

The documentation for the linear voltage regulator says the capacitors on the input and output side are not required. Where would I put caps on the NAND and controller? I have not tested anything yet. I was just thinking about bread boarding, I might have to make some breakout boards for the micro controller and the NAND IC. Thanks for the input, I really appreciate it.

I am not 100% what you are going for, but I have a "Tone" library someone wrote and open sourced for generating frequencies and is non-blocking. I had to make some corrections to the library and added support for the mega 2560, but that portion of the library is now proprietary with my company and I cannot share the corrections I made, however I think I might be able to dig up the library files from the net, or I can look on my work computer, come Monday morning.

I am currently really interested in hardware and hardware design. I have been learning eagle cad at work and in my spare time, I decided to build a flash drive to put on a resume. From what you guys can tell, did I make any mistakes? Its going to cost me ~$66, at a 10 quantity minimum, so I am trying remove any mistakes before ordering. Let me know what you think.

So I guess TempleOS is out ?
