[Cryptech Tech] Alpha Avalanche Noise Block

[Павел Шатов]

Hello!

Fredrik, I've attached my variant of power supply regulator for an 
updated version of avalanche noise block. It will output stable +12V 
with input voltage starting from around +7V and up to +18V. If +12V is 
not enough, you can increase value of R1 to trim output voltage. It 
would be great if you could update schematics when you have time. As far 
as I remember, we also decided to replace hex Schmitt trigger with 
smaller one-gate variant (74HC1G14). After your measurements, we also 
found out, that protection bus transceiver is not necessary.

With best regards,
