nyblcore is... a tiny ATtiny85-based sample player device for diy enthusiasts. powered by a single AAA for ~5-8 hours of battery life. holding 8 kB of storage for up to 1.2 seconds of 8-bit audio sampled @ 4.2 kHz. controlled by multi-functional knobs that modulate tempo, volume, distortion. probability-based. knobs also control the chaos of jump, retrig, stutter and stretch fx. able to load custom firmware / audio using an Arduino or an AVR usb programmer with web-based tool. open-source, wonderfully hackable. there are two options: assembled and diy kit. the assembled version comes ready-to-play while the diy kit requires soldering. the soldering level is beginner. note: the ATtiny85 only supports a single audio sample at a time, but it can be reloaded using the web-based tool, and a ATtiny85 programmer. more information here. purchase policy is available here,
