Features list for v2.0

• Mech. compatible to v1
• modern mcu (stm32)
• Infrared learning capabilities
• 0..-111,75dB in steps of 0,25/0,5/1/2dB
• Mute function
• Individually adjustable user parameter (volume step size, startup volume, balance, no. of input channels…)
• Balance
• +/-10…18V voltage supply
• 2,4,6,8 volume channels possible because volume boards can be cascaded
• optional 1..4 input channel
• optional analog potentiometer to adjust volume
• reduce distortion from mcu with deep sleep mode

2/3 of features are ready/tested. Documentation is “on the way”

I think I need around 2 month to complete the firmware. After that I will order a couple of boards.

I have only 5 kits of version 1 (for a special price) left.

I will be waiting impatiently and I hope to see it.

Great work Meldano!

What is the projected price for these volume controls? What will be built / included? Is the programming already done?

I must confess a display option would have made the setting up much easier, but also to know where one stands re volume setting

A few notes on the excellent paper:
- The remote to use is unclear, but my understanding is it can't be a simple one as at least numbers are needed up to 9
- On my computer titles from 3. on appear at the end of a page, instead of being on the next page
- 3.1 title has a small typo with a double T

MFG

Hi Claude,

Thanks! 🙂

I thik, I will organize a group buy.
The price depends on pcb amount.

I already have a "big" solution with grafic oled and thousend other features.
The goal for project is a small, universal and smart device.

For normal control (vol up/down, input up/down, mute) you can use a small and simple remote control.
To setup the parameter you have to use any other remote from your TV or AVR.

The documentation is only a raw version to show the way 😉

I bought some PCBs in a previous GB but they're still sitting in my desk drawer as I've been deterred by the smd soldering; I could manage it with a template to apply solder paste and then use an oven or hot-air station but not hand/eye soldering - age! For a chip amp project I'm working on I decided to get an Academy Audio module instead.

I'm sure others must be in a similar situation - is there any possibility of offering assembled versions of the new boards?

Send your pcb and parts to me and i can resend ready and tested.
No benefit.😉
