Mail to the US takes longer than in other countries due to security reasons.
Usualy a week or more.

It seems you have left out D9 and D10 in the bom for the psu. Could you advise please. Or perhaps Coulomb as you organised buying the GP parts.

I was thinking that it may be important to post Kari's response to a problem that dhole discovered with the power boards and his 'fixit' here just in case anyone who ordered these boards didn't catch it when it posted in another thread.

yay! got my boards today. They're bigger than I had pictured in my mind...I'm going to have to do some clever layout gymnastics in order to get the enclosure to a reasonable size...with the whole control set from Mikkel it adds up to a lot of stuff to fit in one box. I was hoping to make it all fit in a slim case about the size of a newer DVD player.
