    Thanks for the project. But can we not prepare "5V USB DC-DC step up converter" & "3.3V - 30V DC-DC step up converter" ourselves without purchasing from Ebay ? It would be then complete DIY project, I think ? :)If you could also provide the link for these two with schematics and explanations, it would be a great help for me & others as well ??
