There usually is. not only for the PCB and components but if there are tricky ICs to solder, we can bulk solder them. BUT first, we have to have a target project
Currently the best I can find for bluetooth is AptX and if you want the easier route for such a DAC, having a Raspberry Pi at the core makes life a lot easier on the software side.
I think we start a "group workflow" first. Start learning to work together. Maybe start with a switching amplifier or some kind of discrete class A? Then we move to more complicated stuff? I can do some of it, but no time to do all of it. My work killing me......
Maybe with a TPA3244, or LM3886 or PCM2706 for warmup. Then we move to bigger things? I want to establish some kind of community standard like what CAD software, what kind of microcontroller (if used). Who does the layout, who does the schematics? Who does the prototyping? Who is good at programming? That sort of thing. I tried working with another gang for digital potentiometer volume control. It fell through halfway because could not agree on things.
Maybe can revive my PGA2311 project. Wanted to build a general module for power and volume control with remote for DIY amps. Also had a rotary encoder for manual volume control.
Yes. we can form a group and start doing something simple and move from there.
What you think some SOC solution like csr8675 from qualcomm.
For me I come from digital design background, I do schematics and PCB layouts a lot. and I can write STM32 MCU firmwares.
Don't have much experience in pure analog designs. But will catch up with the guidance.
How and when can we set the community standards ?This post has been edited by xboxrockers: Jun 4 2018, 12:33 AM
