Low-cost - Anolog - Breadboard - Computer (LABC)

X

UNDER CONSTRUCTION

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

Design Study

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.
