2023-11-30 (Th) EWC_Cyberdeck Speaker test

I soldered my voltage regulator to an XT60 connector and adjusted the output to six volts. Next, I added the amplifier to the circuit and confirmed it could turn on safely. I connected three silicone wires to the audio input and put a headphone breakout on the other end since most of these connections are temporary.

I connected the speakers in a few combinations to find the best sound. I should have added a couple of screw terminals instead of soldering and desoldering for each test, but I do not think I did any harm. I tried each combination of my wide and round speakers. I concluded that the paper-cone units could not get very loud without distorting, and the round versions were capable for their size but not powerful enough for this project.

There was a lot of hissing on the system that worried me, but it disappeared when I turned off the audio source or unplugged the headphone jack. The amplifier and regulator are up to the task, but I ordered new speakers.
