			I'll take on the Arduino analysis to determine how much function we can compress into the arduino. Feedback is my primary concern along these lines- I'll check both out.

			I guess we're still indetermined on whether to go buck/boost converter or transformer. I prefer buck/boost but we need more research about sourcing and fabrication along both lines at this point.

			As for the power handling circuit, I assume we can establish H-bridge because we are working with high power specifications.

			Then there is the filter. Start off with LC lowpass I assume?

			And of course, the DC-DC step-down and regulator circuits for the logic (ex. 5V, 3.3V).

			And that should be all of the systems we need to work with.

			Best,

			Yoonseo

			Aaron - no problem.

			Yoonseo - I think we both agree using a digital sine wave generator is the way to go. I've seen it done with an ardiuno and i'm sure something simpler exist's on an IC.

			Another possibility is to use a pulse width modulator IC. Texas Instruments designs a few, the SG3524 being one example. It's cheap and would simplify the design, however, I think something like this might be too high level and pre-packaged. The same argument could be made for the digital reference signal but I think the increase in build quality is worth it. Thoughts?

			Buck/Boost versus Transformer: Component sourcing should be the same level of difficulty for both, I've managed to find sources for the electrical steel and magnet wire as well as the buck/boost converter main components. Although I'm curious about the cost's of each, I'll have to look into that more. I think fabrication is going to prove more difficult with a DIY Transformer, this would require either manually winding the bobbins or constructing a coil winder that can handle #4 to #10 wire and maybe some tooling to accurately punch out the laminations.

			Have a good one,
			Matt
