Mauro Penasa's INV GC/REF GC group buy.

Hi Russ-

Sign me up for a couple as well. I will try to get a BOM together from US suppliers and see what can be done about kits. More as I know it later.

Russ,

Thanks for your e-mail.
Sign me up for one stereo board.

I would be interested in parts as well. That is the biggest hasle over here to find a supplier that can do the lot.

Regards

E&E

Forgot to point that I'm interested in the "Ref" board (as almost everyone it seems)

Cheers

Ah, what the hey... Sign me up for a board as well, Russ. I guess I'll add it to my collection of unfinished projects for the time being

Hey Russ-

Since we are having boards made, why not see if we can get double sided boards to emilinate the jumper wires? Would that add to the price significantly? and where do you estimate we are with the board count?

[gengis]

I will take one.

[Russ White]

Brian,

I am not opposed to doing two sided boards, but I am not sure we have time to get it in for this round.

Plus this is really Mauro's design and not mine. I would kind of like to use his original work, just to have a few around.

I am not good enough at eagle (yet) to do it myself. Plus I think the board is too big for the free version which is all I have.

It seems the count is around 10 right now... maybe 12.

At this rate I will likely get the order in later this week.

Thanks for your interest in this by the way.

Blue?

I'm tempted, but the parts list means very little to me.

If someone said "You can get every component from xyz and it will cost about xxx dollars" then it would be an easy decision. A US source (online) is just as good as UK for me, better in fact as it will be cheaper.

Quick update:

I only have the option of getting green boards right now. Later (if I can get a lrger quantity) I may be able to get other colors, but the first order will have to be green.

The good news is I am able to get very high quality boards specs as follows:

1.6mm FR4 boards
2oz copper
HASL finish
SilkScreen
Green color

I will start accepting payments very soon for this first batch. Keep in mind that while this is a tested/protoyped circuit that this is the first production batch of these boards from this manufacturer I will have received. They should be just fine, but there is an outside chance of manufacturing defects. I am using the Gerbers provided by Mauro.

I ordered a batch a couple weeks ago of a dozen of each of the designs but they were made locally and sent to some college friends for school projects. I did not have any parts for building one yet so I let all of those boards go. Those boards were pretty expensive. I would have had to sell them at $25 just to cover my cost, so I decided not to use that manufacturer. Also, the boards were not as good as these should be, in fact the boards were very thin. These should be quite a bit better.

Lets get a few of these built, and then based on community input evaluate the value of modifications such as dual layer.

The single layer board is a very attractive solution because it does help keep the cost very reasonable while only adding a few jumpers which are easy.

I will post the order page address soon.

Thanks,
Russ
