An audio analyzer from Velleman.

Pretty straightforward build EXCEPT the board-to-panel mounting, soldering screw heads instead of simply drilling holes in the front panel, is bad design and will frustrate some builders.
But it does work, and works pretty well. A very handy quick check of a audio source spectrum. Not something you’d run a mastering deck from, but will ha handy in my eurorack setup.
I made one mod to put an audio jack on the front.
