Have you ever thought, “I’d like to have a synth, but don’t have the room?” If so, then this MicroSynth SMD Kit from Pae Industries is just the thing. As shown in the image above, with its tiny piezo speaker engulfing nearly half of the device’s PCB, the MicroSynth is quite small indeed. In fact, as more clearly shown in the second picture, the device is barely bigger than the included 9V battery connector!
Since this kit uses SMD components, so it’s a bit more work to assemble it but that’s the prize you pay for tiny. While assembly sounds somewhat difficult, if you want a real challenge the kits can be ordered without instructions. While this won’t appeal to everyone, it will certainly earn you some sort of bragging rights.
In action, the device is controlled via a light dependant resistor (LDR), which varies the frequency depending on its resistance value. Since a 9V battery is the largest part of this synth, if you need greater portability, 3 coin cell batteries in series would also do the trick, though you’d need to come up with your own connector. Did someone say “synth keychain?”
