Here are ways to do addition, subtraction, multiply and divide using a multimeter. Addition Addition is very simple! To do it just connect some pots in series. With series resistors their resistance adds up. Subtraction NOTE: If there are 3 or more pots in series, just set them all the way down to 0 ohms. […]

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 […]
