Short video showing:
1 the correct settings
2 problems when capacitance at S5 is too low
3 problems when capacitance at S5 is too high
4 problems when capacitance at S6 is too low
5 problems when capacitance at S6 is too high
6 problems when resistance at S7 is too high

This RNG uses Zener diodes to generate avalanche noise signal, then differential amplifier (and a few analog filters) to eliminate deterministic effects. The noise signal is captured by ATTiny2313 and sent to an FAT32 SD card as a sequence of meaningless hex numbers.
