hi guys,

i've been trying to improve the layout of the deluxe b1 and came up with a idea of removing the scoring line and making it just one whole pcb..

please let me know what do you think about this.. sorry again for another layout..:)
I can't see any improvement here. The new version forces a kind of mounting the whole thing that I don't like. I'd be much happier if you'd keep the scoring line and the ability to separate the two boards.

Sorry about the confusion - I am now also bidding on the one from the states - if I get it I will obviously share the spoils!

Does it matter that they are 6V?

If you are bidding the same item, it's silly to place higher bids between us... 50 pcs are enough for 10 B1 deluxe.

As xaudiox pointed out, you can use a 7806, or add a small diode from the center pin of an 7805 to gnd (out 5.6V)
But I'm pretty sure they will work at 5V too.

Edit: somebody else seems to be interested ;) 2 bids so far

I am the second bidder - let us hope the last one as well!
