Hi Joan,
Congratulations, that’s a very nice build 
, thanks for sharing. Nice to see that you used the 9pin-connector of the Up2Stream board to build your own control panel. I had a similar idea for my boombox but used a rotary encoder for volume control.
Would you mind sharing some more technical details? Dimensions of the box, which speakers you use, which power supply, stuff like that. Thanks a lot in advance.
Best regards,
Sven
