sbelyo 293 Posted June 16, 2019 Report Share Posted June 16, 2019 I wouldn't mind doing a run for all the boards needed for a complete system with volume control and source selection. I know Kerry was working on or has code for the volume control Quote Link to post Share on other sites

I like the larger one because it has a really nice feel as you turn the volume knob (...yes I see it ). I went and added a USB input to the board itself, though this is really overkill - which is why I did it. Here I'm updated with the TX / RX LEDs blinking away. EDIT: I've got to do one more round of cleaning... Hey Kerry - Just wondering, what motorised encoder/pot are you using? I tried googling the # on the sticker, but didn't turn up anything >< Putting my BOM for the boards together now Thanks mate. edit: I’m going with this one in case anyone else is interested, https://au.mouser.com/ProductDetail/688-RK16812MG099 Edited June 23, 2019 by Aive Update Quote Link to post Share on other sites

nopants 127 Posted July 5, 2020 Report Share Posted July 5, 2020 You guys see any issue powering the attenuator with switchers? Was thinking the meanwell stuff used in the smd ss dynalo, irm series Quote Link to post Share on other sites
Kerry 1,477 Posted July 5, 2020 Report Share Posted July 5, 2020 That should be ok. Just keep that power including the ground isolated. 1 Quote Link to post Share on other sites
