I use an oscilloscope (aka "scope") to investigate on the actual electric values that are generated by the studio.

Because the electric potential 3.3V that is put out by the ESP32 and the fact that the 100 KOhm resistors can differ slightly from the given values on their color codes I decided to connect a scope to the studio connectors.

This scope is able to measure two channels at once, so this is perfect to investigate on the real behaviour of the electric flow and…

What BLOBJob produces; some screen shots:

Logging while measuring CHNOPS values: This logs the OPACITY type matrix.

The BlobJob controller produces data that is captured thru the three connectors on the CHNOPS studio.

In order to convert this data into a presentable form it has to be interpreted and has to create the matrix that will be the "BLOB-Art". So the matrix is the heart of the experiment examination.

The matrix is build up from a 30x30 dots…

To be able for CHNOPS to create its Blob-Art it needs a studio to work in.

The studio is build from a buttercup in which three rectangular holes are been cut out and three strips of aluminium foil is slipped in and with a piece of tape constrained, thereby closing the buttercup in order to prevent CHNOPS from escaping.

Since CHNOPS needs to put out two parameter values (color and opacity) the studio is designed as shown in the image:…

So I wanted to do more than just setting my blob up to create a map of my city.

Inspired by a video about Physarum polycephalum in which electric potential is used to create music I wanted to investigate the possibilities of the use of electric potential on Physarum.

So I started with some desk research…
