Starting with 100000 DM in the past, the price drops to under 1000 €. The goal is to offer a starter set about 100 €. + +The "Low-cost Anolog Breadboard Computer" - short __LABC__ [ˈlæbˈsi] - is a __open source / open hardware__ project to offer __breadboard__ based development that 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.
