I've got the permission from Dr Gilmore for a second run of boards, so let's do it again.   Linky to the spreadsheet: https://docs.google.com/spreadsheet/ccc?key=0AoNVeoQi85GgdFVrMmtReVpWNVBsQUo2Sl9iSkItM2c#gid=0   Please take a look at the notes before putting your needed quantity.   If you want something extra (like a single PSU or amp), just put a note under Extra Requirement column.   The Megatron is not fully-tested so if you really want to try it, do it at your own risk.   Silk
