#making #audio Second completed project in the last few days. Wanting a "throw-away" speaker with a large-enough cone easily exposed (explained letter) and having no amplifier that I could use (speakers that I don't want to take apart, but have an easy-connect proprietary ends I didn't want to mess with)... I found a $7 Right speaker from some Pioneer system.Bought a $14 amplifier component from amzn that had volume control, easy screw terminals for power, audio in and speaker out. It is mono, but that suited my purposes must fine.From my collection:12 VDC power supply with inline switch3.5mm Audio Jack5mm center-positive power jack that matches with the power supplyperfboard, wires, screws, and an old "space" themed hotel access card. Made quick "breakout" boards for the audio and power jacks, then proofed that it was functional. Not content with bare components hanging, I modded the speaker box to house it all. Used the hotel card as the plate/panel. Nice and tidy!
