[sorenb]

Another round of Carbon etc. 
state your interest here

When ever there are enough boards for ordering participants will be asked to pay estimated price. Shipping will be added whenever the cost is known.

Boards from PCBNet. Distribution via @mwl168 in US/Canada, and from Denmark, Europe for the remainder.

The thread title says Carbon v7, but the spreadsheet says v6. I'm a bit confused... are there v7 boards available at all?

[sorenb]

you are right, the Carbon boards are v6 ....but since we are in July I thought why not call the Group Buy V7.0 ;o)

[Tinkerer]

As long as there's several group buys going on, any chance we can get one for the updated output boards (V2) on the Nanotube?

[Arthrimus]

@sorenbIn the chart, do the grounded grid and carbon fields denote a pair of boards or just a single channel?

Any chance of psu fat boards?

[palchiu]

Single Skinny PS is this version?  ->  kgsshvpssicfetsinglenewleft.zip

sure, if that is what ever people wants. The functionality is the same as Skinny's, only the dimension is different. FAT doesn't fit 2U upright, whereas Skinny does.

Yes, both LEFT and RIGHT is in the GB. You only reference the LEFT

[palchiu]

[jose]

If offered, I'd take a couple.

[sorenb]

@jose Thanks buddy, but please state your interest here :o)

@Tinkerer @chiguy Circlotron Output board v2 and HV900 added to the mix.

Just throwing this out there. I like the split GRLV boards. They make layout design choses more versatile. You can put them together for virtually the same footprint as a full size dual board. The only consideration is that the transformer secondaries cannot be CT.

Thanks sorenb, I need four Carbon PCB.

May I pay by PayPal?

when ever we get to that point, yes you can use Paypal.
As for your order, putting it in the sheet is adequate.
For now we are probing interest, the drill is like:

Probe interest, people state their orders in the sheet
getting quotes
people confirm their order by paying using Paypal
the order is placed
When I and @mwl168 get the boards we ship to the participants and add shipping cost (mwl168 ships US/Canada, I do outside gods own country to keep shipping low)
after some weeks boards are in various hands

Fair point and hereby changed. The golden Reference Low Voltage will be the split board version (the number in that column will comprise a set (left + right).

Thanks, sorenb.

So, may I pay now? How much is the shipment fee?

I live in Taiwan, and what shipment you will use? UPS? DHL? or something else?

I'd prefere to wait with people paying until we get firm quotes and are ready to make the order.

Shipping depends on your individual preferences. Some wants tracking/sign-off, others don't care and go for regular mail.
1kg for Taiwan using UPS is ~55USD, regular mail is ~15USD.

So far there has been no loss of packages using either service ( ~100 packages in total for the past three group buys).
A few packages was on its way for weeks before showing up using regular mail, but that is about it.

mwl168 wanted a amp board with the ground plane, i have posted 2, the second one looks better.

no other changes, all the parts in the same place, same size,same number of holes etc.

second version routes the servo around the top.

Interesting, I was discussing this subject yesterday. Does a Ground Plain (in theory) result in a better PCB in this application?

[nopants]

ground plain

[MLA]

Plainly, yes

I'd say it will result in postponed ETA rather. Don't think applying the PCBs will improve anything though.

[kevin gilmore]

i don't think its going to make any difference except that it will make it easier for some builders to introduce shorts, or fancy resistors leaking to ground etc.

Just to confirm, is the number we put in the GRLV column for total number of boards or number of left+right sets?
