Open Source Platform Projects at ASR

A physical remote control with buttons and rotary encoder(s), and maybe an oled display, for those who don't like touchscreens or phone apps. I've proposed something similar before for using the MOTU AVB series interfaces as a preamp, using their network API, but the same hardware could equally be used with LMS, MPD and probably others. There are boards combining an ESP processor(hence WiFi and sometimes Bluetooth), battery charging, and sometimes an oled display (and possibly accels?) for ~$10-15 on ali, ebay etc. The project would supply a reference hardware control board for buttons and encoders, and an easy way to map them to remote control commands on whatever we use for the streamer project plus possibly others (kodi? Roon?). Similarly we'd need info for display if one is present. Bonus points for a charging dock with pogo pins instead of the usb connector, or wireless charging.

This Clever Dial Can Selectively Resist Motion and Provide Haptic Feedback

Scott Bezek's SmartKnob View uses a round LCD and brushless DC motor to provide users with programmable, degree-accurate haptic feedback.

3 of these and a 4x7 touch screen. Volume Control, Quick Access menu, and Dedicated interface one.

Interesting project - the handheld version they're working on is closer to what I was thinking of.

Magnetic USB charging cables work nicely.

Hello,

I designed a digital input / DSP / Amp based on the TI TAS3251 chip. The intention was:

• have an open platform, where all configuration options are accessible,
• use "good" components and not cut the corners on the quality of those to squeeze best performance from the chit,
• possibility of several amps working together for active 2 ways, 3 ways...

This is a stripped down version of the TI EV board, with Würth coils, and good input caps.

The board is described in https://www.diyaudio.com/community/...controlled-integrated-dsp-amp-tas3251.325826/

Would this fit with spirit of Open Source Platform Projects at ASR ?
