How is payment accepted?

I can do VISA/MasterCard, PayPal, money orders, cash or cheques from Canadians drawn on Canadian Banks.

For this 1st round of boards i may consider barter as well.

Note: this 1st batch isn't really a group buy -- SY paid for the boards & i swapped him some stuff for the ones he sent me.... but i hope that in the end this 1st batch ends up paying the tooling costs for a large group buy.

I've been really thrown off by the time off to deal with father-in-law death.

But -- allegedly -- some boards (and enuff LEDs for a "Red Light District") are on their way here and i will sell some out of that batch to deal with immedite needs.

R these the ones you were talking to me about a few days ago in the car about ?

Hi Dave, I'm from the Philippines, so how about some "Lechon" or "Adobo" for trade?
😀

Seriously, fire me an email if you can. I'll pay by Credit Card.

or

How about a pair of Western Electric 407A 😀
 
want to buy boards

I'd like to buy some boards using VISA for shipment to Sydney Australia.

Can you please point me to where I can see what types are available and what each board does so i can figure what to order?

Also how to calc shipping and pay.

Many Thanks

If it's not too late (hope not), I would very much like to order 2 sheets (12 pcb's?) for myself.

Once i get the boards and figure everything out, i'll let everyon know. For this round there won't be too many boards so i'll probably set a limit to how many people can have so that we can get them spread around. SY & EC8010 are already working with the boards and i expect those that go out in this round will be part of the documentation.

At this point if you want to get in the queue send me an email with the number you'd like (i've already got a list started). 1st class letter mail should cover a small quantity of boards and that is $4 USD for under 100g to anywhere the post goes (except USA & Canada which are a bit less)

I've already got places for boards to sit on the botom of a LTP phase splitter and as anode load for a common cathode DC coupled to a CF with a CCS load....

Update?

Any news in the last couple of weeks? Has anybody had an opportunity to use the prototype boards yet? I'll be returning to a pre-amp project some time in the next few weeks and will probably want to implement sources and sinks as the first tweaks. I'm currently on the wiki and can wait until the production distribution, unless you have excess of the first run that you need to get rid of (Dave?). Otherwise, I'll continue to wait patiently. Actually, I think I have some of Doc's C4S boards somewhere in the piles of stuff that we all seem to accumulate, but I was kind of hoping try these boards on the next project.
