Ksimus is a circuit simulator that allows you to build digital and analog circuits with discrete components and simulate them in real time. Ksimus does have its limitations though.

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

Implementing standard UART communication required use of Silego’s GreenPAK analog and digital blocks, with the end result being a Geiger counter that offers real-time radiation measurement. The Geiger ...

Ah, the humble Commodore 1530 Datasette drive. It never enjoyed much popularity in the USA, but it was the standard for quite some time in Europe. [DerSchatten13] still uses and loves his 1530. When a ...

The challenge in measuring low frequencies is that the counter gate time is often too short for the signal relatively long period. This non-critical circuit automatically multiplies an input single ...
