About the Skidl experiment PCB
Skidl experiment is an open source PCB design by RepRapLtd, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 10 × 14.2 mm, with 6 components from 2 distinct parts.
Other key parts include the LM741. By type, the board carries 5 resistors and 1 IC.
From the project
Project to make a photonic neural network using photochromic material for the synaptic weighting adjustments
This is a project to create a neuromorphic analoge neural network. I wanted to get away from using conventional computers (including parallel graphics processors) to do neural simulations and to make something that is a lot more like a real brain.
What I propose is similar to the early work on perceptrons by Rosenblatt from the 1950s that has now been all but abandoned because today it’s much easier to solve a problem by writing some software to do it than by designing and building some electronics to do it. Easier maybe, but at least today we have the advantage of 21st Century electronics.
