Thanks for the awesomely organized build thread Ecky! It is super helpful.
Last night I ordered the
two 90V LED drivers from amazon. The total was about $25. They should be here in a week or two. I think I have the rest of the components for the charger here minus a nice 200V panel voltmeter. For now I think I'll just use my multimeter. I'm hoping this won't be something I use THAT much.
