THE ANALOG THING (THAT) is a high-quality, low-cost, open-source, and not-for-profit cutting-edge analog computer.

THAT allows modeling dynamic systems with great speed, parallelism, and energy efficiency. Its use is intuitively interactive, experimental, and visual. It bridges the gap between hands-on practice and mathematical theory, integrating naturally with design and engineering practices such as speculative trial-and-error exploration and the use of scale models.

Dynamic system modeling on THAT can serve a variety of valuable purposes. It may help understand what is (models of), or it may help bring about what should be (models for). It may be used to explain in educational settings, to imitate in gaming, to predict in the natural sciences, to control in engineering, or it may be pursued for the pure joy of it!

Analog computing is one of three major computational paradigms (analog, digital and quantum). As digital computing approaches the limit of Moore’s Law, analog computing offers a strategy to diversify today’s digital monoculture. Analog computing is:

  • ideally suited for dynamic systems modeling
  • ideally suited for neuromorphic AI applications
  • significantly more energy-efficient than digital computing
  • inherently safer than digital computing in the face of cyber threats

THE ANALOG THING is designed to allow an extensive range of analog computing applications with a small set of calculating elements.

Circuits that perform integration over time.

Circuits that add inputs continously.

Circuits that compare inputs to support conditional functions.

Interfaces that allow daisy-chaining mutiple THATs to create arbitrarily large programs.


Rotary knobs to provide user-defined inputs.

Circuits that multiply inputs continously.

A digital panel meter for precision measurements of values and timing.

An interface for controlling THAT digitally to develop analog-digital hybrid programs.


With THE ANALOG THING, you can model dynamic systems including:

  • market economies
  • the spread and control of diseases
  • population dynamics
  • chemical reactions
  • mechanical systems
  • a variety of mathematical attractors

As collateral learning benefits, THAT offers introductions to:

Inseparably linked with rates of change and the accumulation of quantities, analog computing offers a practical approach to differential and integral calculus.

With computing elements built around operational amplifiers, analog computing enables users to gain a hands-on understanding of analog circuits.

Applicable in adaptive control systems, analog computing offers a practical introduction to control engineering.

We are planning to make THE ANALOG THING available at a regular price point and with an educational discount.

Both price points will be offered on a not-for-profit basis.
