The Business Card Synthesizer is a tiny synth that can be connected to a Business Card Sequencer, other synth gear, or played by itself.

These fun little kits were introduced at Knobcon 2018 as a build workshop. Now you can get your very own.

Headphones can be connected directly to the output of the synth, and there are plenty of knobs to play with, so you can easily make noises anywhere.  Great for learning about synthesizers!
