Hi Tibi,
Do you have any photos of the displays in operation?
I've found photos of the OLED display in people's projects but I'm still not certain what the LCD display looks like. What colour is the backlight for example?
With the LCD version, do you think it might be possible to switch the display for a compatible LED matrix display later on to tweek the aesthetics if indeed there are pin compatible versions of both?

OLED is blue and LCD is STN negative, blue transmissive.
All displays must be compatible with MAYA. A special routine is written in MAYA microcontroller to drive each display. Each display employ different controller or compatible ones.
Is difficult to make pictures as these do not render display color correctly.
Herebelow are few displays compatible with MAYA.
OLED - WEH001602A
VFD - Noritake CU16025 UW
LCD - RC1602B-BIW-ESX
LCD - RC1602B-GHW-CSX
LCD - RC1602B-GHW-ESX
LCD - RC1602B2-BIW-CSX
LCD - RC1602B2-GHW-CSX
LCD - RC1602B-BIW-CSX

Thanks for that. Someone has a photo of their build using the blue transmissive type on another thread so that's fine. Think I prefer that to OLED so I shall keep my option for the LCD one.
Thanks.
Thanks.
Oh hold on! VFD would be perfect at a later date. So will this replace the LCD directly, no other modifications?
All mentioned displays are based on HD44780 controller and can be interchanged. Any HD44780 display can be used for LCD MAYA version.
If you buy MAYA with LCD, than single OLED display available is WEH001602A.
If you buy MAYA with OLED, than display controller is WS0010 and there are many more OLED display available.
Between VFD and OLED, I personally prefer OLED.

GB is closed. Many thanks to all who expressed interest in Maya and Hans VolCB board !
Next I'll get a final quote for 50 VolCB boards. I the mean time I know that Hans is looking to offer VolCB boards ready mounted and tested for those who do not like hassle with smd parts.
Before going further and start collecting money, I'll wait for Hans decision about VolCB ready mounted boards.
Please also note that some Maya orders will be shipped right away, as we have a small stock.
Others will have to wait 2-3 weeks more.

Hey, sorry for this but can I add to my order and make it 2 LCD Maya controllers please? Was thinking about it last night but was too tired to remember to change the spreadsheet..
Hope that's ok?
Also i'm happy to wait 2-3 weeks so feel free to prioritise others.
Thanks, NATDBERG

I just posted this in the Remote Control Thread.

I got PCB quotation from factory.
VolCB boards are 7 euro each ex VAT 20%
4 input select boards are 28 euro each ex VAT 20% (price is high because there are only 10 GB subscribers).
Next, I'll contact each GB subscriber and ask for paypal details. After that a paypal invoice will be send to you.
I would appreciate a fast payment, so I can put these boards in production soon.

Thanks, Tibi!
It is my understanding that the Maya boards come pre-assembled and the VolCB and 6 Input Board are PCB only. Is that correct?

Yes, Maya comes mounted, programmed and tested, while VoICB is only bare PCB.

Hi,
Do you have many images of the display graphics that are programmed for the controller? It does seem to be something lacking in your promotion of your full product - I have to rely on photos of other people's builds.
For me, if it wasn't for the BPPBP, I would be judging the controller much on the looks of the graphics - no-one wants a great sounding preamp that annoys them visually every day! 🙂
Here's one for the LCD - Is this how the volume control graphics look?

A question that has just occured to me, is it easy to program the volume level indication for Hans' VolCB so that it is accurate in -dB level?
Pictures and graphics is something I need to add to promote our volume-controller. We are working on this. Graphics are dynamically changing and that image is when you select an input and change volume.
Hans' VolCB it is accurate in -dB as long R-2R resistive network is designed log in one 1dB step and this is the current case.

The build you have used is lemons, I think he has replaced the stock screen. But it looks really nice indeed

I think a small addition to the above is needed.
The steps in the Maya display go from 0 to -63dB in 1dB steps.
The VolCB has also 1dB steps with the same 63dB range, however with the proposed resistor values it will go from +6dB to -57dB.
This means that you have to add 6dB to the value you see on the display to get the real gain.

Oh ok, that's a shame as I like that one - not too harsh on the eyes like the blue ones can be.
