Inside the digital clock from a Soyuz spacecraft

We recently obtained a clock that flew on a Soyuz space mission.1 The clock, manufactured in 1984, contains over 100 integrated circuits on ten circuit boards. Why is the clock so complicated? In this blog post, I examine the clock’s circuitry and explain why so many chips were needed.

RSD RISC-V Out-of-Order Superscalar Processor

RSD is a 32-bit RISC-V out-of-order superscalar processor core. RSD is very fast due to aggressive OoO features, while it is very compact and can be synthesized for small FPGAs. The key features of RSD are as follows: Install the following software for running simulation.

How to interface a 5V output to a 3.3V input. – next-hack.com

Many times we must interface 5V to 3.3V devices. This occurs very frequently on Arduino, but other applications need 5V to 3.3V ICs or systems to communicate. For instance, imagine you want to connect to your Arduino Uno, which works at 5V, a 3.

How A NES Controller Works

Have you ever wondered why there are only 7 pins on the NES controller port, but 8 buttons (plus power and ground)?  How does the NES know exactly what button is being pushed?  Also, how long does it take for the console to know that you’re pushing a button at all?
