GB for R2R audio volume / input selection pcb

Is that possible with some modifications?

Yes, one bypass (direct) input is already included.
Schematic is available at :: vicol audio :: >> Products >> DanZup R-2R/shunt volume controller

Well thats perfect.. I'm in for a Balanced Set, so 2 relay and a control board. Will need the programed Atmel aswell...

I'm interested in two stereo PCB sets with atmel microcontroller.

Below is a link to a google-doc with persons who registered to this group-buy till now.
There are few details which need to be cleared.
Persons who may like to have access and edit personally, are invited to send e-mail address to office@....ro (see my signature)

I had a look on the google-doc.
But there are some questions left:

• what are the advantages/disadvantages of shunt/r-2r version. Which is better? Where I can find information concerning the differences between the 2 principles?
  
• is the ATMEL programmed and can I use the same ATMEL/program and pcbs for LED and LCD?
  
• what is enclosed in one kit?
  
• were ther any estimated prices given?
  
• who I have to inform which kit number etc. I want to order?

I hope I haven´t missed the point while reading the thread.

Here are two links which will explain you, in detail, all advantages/disadvantages of different resistor networks topologies.

Atmel is programmed to support LED or LCD, but not both in the same time, as there is no enough space on flash memory.

PCB and all components.

We are going for full kit only if 100 pcb's will be ordered.
Estimated price / pcb is 12 euro.
On other hand, will provide full BOM with links to Elementy i podzespo?y cz??ci elektroniczne - TME - Electronic Components , so you can just click and add to your shopping basket all the components. I think is more fair like this.

What numbers will be required for this gb to go ahead?

At least 80 pieces of PCB to start the production , but better 100 of that for order......

[evansp]

How is the controller programmed?
Is it supplied by you pre-programmed?

Hi again,

I just want to confirm that I am still interested in balanced version, but I am really concerned about the time necessary to reach to 100 PCB.

Furthermore I don't understand the lack of interest in the volume control..might be missing something.

Cheers,

Max
