The Crafted Mind: Building an electrolytic memristor neural network, Part 2

An electrolytic memristor neural network can be built from cheap and readily available alumina powder. This second article in the series details my experiments toward building a real world device based on the concept. I continued experiments with the thin firm memristor, and then created a new pasted/powder version.

This story is a continuation of my experiments detailed in my previous article An Experimental Open-Source Memristor/Programmable “Diode” published on Jan 4, 2021 that details the theory of operation of my “electrolytic memristor”. The diagrams there still apply to this version, with the exception that no separator is necessary, the Alumina/Carbon paste is also the separator, and the pH gradient and functionality are identical. The memristor is a real device I created, and the neural network is a device I’m working towards creating.

Replicating the Original Experiment with Additional Data

On a long-overdue post-vaccination visit to my parent’s home last week, my father (a recently retired Electrical Engineer) and I built my memristor from scratch and ran it through some tests. I did add some iodized sea salt to this version, but later analysis seems to indicate that it didn’t alter the behavior much — and may not have been necessary. It worked…
