The Analog Thing
The Analog Thing (abbreviated as THAT) is a a high-quality, low-cost, open-source, and not-for-profit cutting-edge analog computer analog computer developed by anabrid under the brand Analog Paradigm for educational and recreational purposes. THAT will be available for sale at a net cost price of around around €300. The component list, circuit diagrams and circuit board layouts of THAT are all Open Source. Information on how to build THAT from scratch and how to operate it can be found on this wiki.
Version 1.0: Specifications and Photos
The prototype consists of two main parts: A top PCB with gold-plated through-hole sockets suitable for 2 mm patch cables, and a base PCB, which contains the main electronic circuitry, the manual controls and ports for external connectivity. Additionally a third party voltage instrument (PM438) is used to display coefficient values and, in repetitive operation mode, the operation time of the analog computer.
