We are not going to sell full kits under 100 orders.
What we can offer, at this time, is pcb and atmega microcontroller ready mounted and programmed.
As soon wiĺl get a decent price from pcb manufacturer, will let you know the price of above.

We have factory price. 🙂
The price for PCB + programmed atmel will be 24euro.
This not include shipping which may vary from location to location.
If interested, please drop here a message and I´ll open the webshop on 7 June 12:00gmt.

Ok. I would take a complete kit for r-2r-version for balanced stereo amp and an additional relay board for switching digital sources.
Whats about the price?
I am still in. (Kit = pcb set)
Regards and thanks!

Interest to purchase
I'm interested at this price providing ship to UK is reasonable.
Please confirm that this price also now includes new buffer board.
ie I assume price is for all pcb's plus preprogrammed megachip all other components to be supplied by purchaser.

Shipping to EU countries is 16euro with tracking and receive signature confirmation.
Standard postage to EU is ~10euro.
I confirm that the board include output buffer and atmega8 microcontroller programmed and soldered.
All other components will be available via an online BOM - click and shop - We'll do our best to provide codes from a single distributor TME, Mouser or Farnell.
Full documentation with detailed mounting will be available online and posted here as well.

will the end product look like this ?
Price ? what does it include ?
An externally hosted image should be here but it was not working when we last tested it.

The price only for PCB + programmed soldered Atmel Atmega16 will be 24euro.
Components as stated in BOM remain for everyone to buy from your favourite component online magazines : TME , Mouser or Farnell. .
This not include shipping which may vary from location to location.
If interested, please drop here a message and I´ll open the webshop on 7 June 12:00gmt.
See here for how it will look the pcb ( 90% will be like the old batch of pcb ):

Or like this 🙂
So you´ll have to specify LED display or LCD.
In fact, on the webshop, you´ll have to choose between two products.
But beside display board, you´ll get relay board, rotary encoder board and buffer board.

I'm more interested in a complete kit ? Will you offer that ? I'm more interested in it, if there are 2 buttons for volume, one for up one for down ?
Due the quality of the components, we like to offer, the total cost of the kit will be over chinese clones and we can not be competitive with low quality & cost chinese kits.
I think is more fair to have a BOM. You can choose components listed by us at the distributor price, or select what you consider is the best.
About 2 buttons for volume, if more people will request this, we can easily replace rotary encoder. However, I personally consider that is more elegant to have a rotary encoder, but final decision is yours.

Will release for you such a firmware in the near future .I'm more interested in it, if there are 2 buttons for volume, one for up one for down ?
Just replace the encoder with 2 push buttons and the job is done .
Hi Tvicol, I recommentd 8bits or more relays uses in the volume control, for the reason that 6bits is really not enough for a suitable attenuation.
You can get 48dB attenuation with 8bits relays
also, 36dB only in 6bits

Lu,
Strange ... We got around 63dB attenuation.
I hope we are talking about same volume controller. 🙄

That is really strange ^_^
We can only get X bits*6dB in original R-2R attenuator, here X is 8, so 6*6=36dB. in theory
But if the resistors are not only R and 2R in your attenuator, you can get other attenuation value.
here is a simple example:
6 bits R-2R resisotr network,
alll the switch are off you can get 'mute' in the output
one LSB switch are on, the others are off, you can get 20log*(1/64)=-36dB
two LSBs 20log*(2/64)=-31dB
three LSBs 20log*(3/64)=-26dB
four ... -24dB
......
63 LSBs 20log*(63/64)=-0.14dB
there are 1~63steps available in 6bits relays, but it is not mean that 0~63dB attenuations
no exception ^_^
maybe different resistor value is good to 6bits atteuator if you want to get more attenuation.

Exactly what I thought. 😉
We are not talking about same product.
