Analog computers have a history of over 80 years and are still fascination in this modern times. Starting with 100000 DM in the past, the price drops to under 1000 € today. The projects goal is to offer a starter kit about 100 €.
The "Low-cost Anolog Breadboard Computer" - short LABC [ˈlæbˈsi] - is a open source / open hardware project to offer breadboard based development to hobbyists, pupils, FabLabs and hacker-spaces for education and fun.
The breadboard is populated with singe purpose (adder, integrator, ...) tiny electronic boards (PCB) - the so called compute-modules. Each module is powered via its pin-headers and provides the inputs and outputs to the breadboard. The connection between the modules is done by jumper-wires on the breadboard.
By positioning the compute modules in data flow order (graphic layout) it is easier to follow the schematics and for most connections shorter cables (jumper-wires) can be used.
The control module provides all necessary voltages and hosts a Raspberry Pi Pico (W) for control, ADC and DAC. An USB-connection can provide a connected PC with measured data. This builds the bridge to simple hybrid computing.
See the WIKI for more details
To see how it look and how it can be handled a design study was made. Playing with the dummies gives more expiriance about size, pinout, components, cabeling on breadboard, ...
Note: The 'PCBs' are made of lasered paper sheets and are not functional.
