All Goofyness Shall Be Revealed #5—the Barbie Sputnik
Yep, the circuit bent Barbie Karaoke gizmo.
Seaweed Factory’s Fancy Lady Delay is a high steppin’ rackmount cousin to/inspiration for the decidedly more ad hoc Barbie Sputnik. Also the good folks at Casper Electronics have lots of info on Barbie Karaoke bends.
Oddly, there must be some kind of Borgesian back story on the circuit board revisions of this echo enabled widget. The Sputnik’s board is indeed very similar to, but distinct from the Fancy Lady’s, and further still from the Casper E. version. As I was lucky to even suss out enough to do what I did, I’ve no documentation to offer you (or myself, at some later date).
Such mystic goofyness being the case, don’t bother reading the crude labels in the photos above. Suffice to say that on the right panel (starting at the upper left corner) there’s a mysterious feedback mode selector knob at, a trim for the mode selected (very context dependent yada yada), a master on/off toggle for the mode, a fine-ish delay time knob, three dangling touch wires for slowing or speeding up the delay time, a coarse delay time knob, and a right hand 1/4” speaker out. The left panel has a single trim control for two fdbk. points, switchable by the two toggles below it, and another point with on/off and trim. Plus a left 1/4” speaker out.
The Sputnik was named (not by me, but by a seraphim) for its satellite-like appearance with switches & knobs protruding.
