Simplest analog computer
In this post I will show you how to make a analog computer using just resistors, switches and a 100 micro ammeter. Here’s the schematic of it: You can see the idea on how this analog computer works, it uses ohms law to get current from resistors in the circuits. Each current is limited in …
