I have add a column in the table for select or not the option of buying PCB with the
logic IC (EPM3064), soldered and programmed.
I will ask an extra 15 for that.

Hello,

Currently, only 6 cards are pre-ordered.
I wait a few more days and if all buyers are ok, I would start the group buy and then I would send Paypal invoices .

HI frex,

Was hoping you'd get ten though!

Thanks,

Hi Frex,

thanks for your great projects, why don't you list this GB in the appropriate section (Group Buys) for raising the number of people interested in it?
regarding myself I'm fine with 6 pcbs order, but maybe others could be eventually interested, too.

kind regards
Vale

Hello Valeriano,

It's a good idea. I've added a topic about it in the group-buy section.
We will wait a little then.

Hi Frex.

almost there 9 pcbs in preorder, only one missing.
if all participants agree, two more weeks for closing this GB should be enough. what do you guys think?

regarding input buffer stage.. reading the discussion in original thread DIY Analog-to-Digital Converter project.Audio measurements tool post#32 .. you choosed OPA134 for its low input bias current and its low current noise.. for making hi-Z sources measurements.
what do you think about OPA140 and OPA827 ? these seems to have better specs overall vs OPA134

thanks
regards
Valeriano

Now, 11 PCBs are pre-ordered.
I think to closed the buyers list this sunday.
I will send then all individual Paypal invoices.
to recall, the price will be ;
1 PCB = 35€
2 PCB = 65€
+15€ with EMP3064 soldered and programmed.
(The price include worldwide shipping in priority letter, but no insurance is include.
If you want a registered letter, ask me before !)
A full design folder will be sent by e-mail when payment is done.
Regards.

Frex.
