Qocka is a stand-alone crptographic random number generator with three sources: 1) quantum RNG band on beam-splitter and light emission just above the threshold, 2) elementary ring oscillator in differential configuration, 3) fast self-timed ring oscillator. It uses Toeplitz randomness extractor and cryptographic hash extraction using SHA256. It has Ethernet connectivity.

PulsePins provides a programmable timing core for dozens of digital pins, suitable for pulse sequences, triggers, multiplexing, and general lab 'digital glue'. PulsePins is open source hardware and it is very hackable.
