Makers and computer enthusiasts interested in building their very own analogue computer, may be interested in a new modular analogue computer kit showcased by the grappendorf.net website this week. The kit consists of various 100×60 cm PCB cards which can be connected together with 2.54 mm jumpers. The analogue computer has been inspired by Dr. Vogels Home Brew Analog Computer and there are currently nine different modules available.
“Inspired by Dr. Vogels Home Brew Analog Computer , this kit consists of various 100×60 cm PCB cards which can be connected together with 2.54 mm jumpers. Each board implements a specific section of the analog computer by Dr. Vogel. Connect the various input and outputs of generators, adders, integrators and multipliers to compute different mathematical functions.”
“Each board implements a specific section of the analog computer by Dr. Vogel. Connect the various input and outputs of generators, adders, integrators and multipliers to compute different mathematical functions. This kind of electronic computation was used for real applications in the years 1950 to 1970. You could use them to solve quite complicated differential equations and display the solution with on an oscilloscope. Two of their main disadvantages were bad calculation accuracy (due to the tolerances in non-linearities of the electronic components) and a limited value range (e.g. due to clipping of the op-amps).”
