Finished project on the ground in front of Coover Hall at Iowa State University.
Front panel layout for interfacing.
Introduction
I made a basic proof-of-concept analog computer using the TL082 op-amp chip.
This computer can be made DIY using the paper circuits I designed. I decided to make the paper circuits in modules so a computer can be built using however many of each one desires.
Functionality
The computer can do summation, subtraction, integration, differentiation, and inverting. The outputs can be patched into other inputs, along with an included DC voltmeter. The device takes bipolar 12V as power.
How It Works
The circuits use the TL082 chip with resistors and capacitors built on paper circuit. The inputs/outputs are screws that alligator clips can clip onto.
The TL082 op-amps are in the basic configurations for their function. I tested resistor/capacitor values for a decent frequency range of around 500-15000 Hz for the calculus operations.
How to Make Your Own
This project can be reproduced using the resources provided below.
1. Choose component values.
2. Print the paper circuits.
3. Solder the paper circuits. Here is a guide on how to do this.
4. Design a panel layout, or use mine.
5. Construct a panel, whole box, or keep the paper circuits as is.
6. Wire your power and ground rails together.
