About the Building blocks PCB
Building blocks is an open source PCB design by mirdej, published on GitHub. It is a 2-layer board measuring 99 × 70.7 mm, with 162 components from 48 distinct parts.
Other key parts include the LM393, TLV3201, NE5532, C3113 and LMH6643. By type, the board carries 50 resistors, 35 connectors, 30 capacitors, 17 test points, 11 ICs and 9 diodes.
From the project
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann
The Synkie is a modular open source analog video processor, developed by Michael Egger, Max Egger and Flo Kaufmann. A bit like the venerable modular Moog synthesizer it lets you toy around with the signal using patch cables – but this time not producing sound but images. It is an instrument for video, a playground, a platform to explore new ways to transform a video signal. Synkie is still in development, we constantly develop new modules – and even the base specifications may still change over time.
