Hackaday Supercon 2022: Adrian Freed - Unusual Circuits with Soviet-Era ICs

After a career developing pioneering audio and music technology such as the DAW and OSC, Adrian Freed has contributed to the emerging field of E-textiles. He designs ICs recreationally and shares foundational tools and technology such as Arduino audio and cap. sense libraries. He plays country blues guitar and is learning Son Jarocho. His life-long commitment to creative uses for analog and digital computers is reflected most recently in interactivity enhancements to Adobe Premiere Pro and an add-on board for the SuperCon6 4-bit computer badge

Soviet Era ICs were not just copies of designs from the West. Many interesting re-implementations and new designs will be demonstrated including: a wide-range VCO with a quad XOR gate, programmable opamps, uncompensated power opamps and transistor arrays in DIP packages with integrated heat-sinks and Thyratron Neon Tube counters. Contemporary new ICs from Latvia will be shown.
