Hi guys,
I built my own HIFI amplifier from an Up2Stream amplifier board. Everything worked very well for me. I built the housing for the amplifier from an old radio microphone housing.
At the front I screwed on an additional black cover. Then I glued on the RGB LED and the IR receiver with hot glue. I connected the board to a notebook power supply 19V 5A.
If you have a metal case, you should mount the WLAN and BT antennas outside the case. Drill a hole and lead the antennas outside. In my case it was a bit more clumsy. The housing of the wireless microphone already had 2 wireless antennas, I connected them directly.
I am very happy with the amplifier, wanted to show you all, maybe someone wants to build something similar.
