Inside the digital clock from a Soyuz spacecraft

By Emanuele Signoretta on April 5, 2020

In this blog post, I examine the clock’s circuitry and explain why so many chips were needed. The clock also provides a glimpse into the little-known world of Soviet aerospace electronics and how it compares to American technology.
