This is just awesome. The Business Card Synthesizer is a tiny, fully-assembled analog synth that's literally the size of a business card. Don't let the size fool you—it's packed with features: multiple wave shapes (pulse, square, triangle, saw), two LFOs, an attack/decay envelope, a low-pass filter, and even sample & hold. You can play it by itself with the manual gate button, connect it to the matching Business Card Sequencer, or even patch it into your larger modular setup. Plug in some headphones directly and you've got a portable noisemaker perfect for learning synthesis, sketching ideas, or just having fun. It needs a 7-15V power supply (not included). A super cool, creative gadget for synth lovers and curious beginners alike.
