CHNOPS BlobArt: The BLOBJob controller to convert BlobArt to data

[Jos Richters]

In these part I want to tell something about the conversion from the CHNOPS electric connection to usable data. I call the the "BLOBJob controller".

I use an ESP32 microprocessor to put a 3.3Volt potential on the three connectors that are attached to the BLOB studio.

The studio is covered with an aluminium sheet in order to prevent to much light enter because Physarum polycephalum prefer to grow in relative darkness. The ESP32 is connected to the aluminium connector strips and is powered thru the USB connector. This USB connection also relais the data to the computer in order to be processed for further use.

Because CHNOPS is a living organism, the resistance changes in conduction of electricity during its life phase. This change is converted by the BLOBJob controller in the BLOB-Art.

I used the scheme on the right to distinguish between the two parameters: color (left) and opacity (right).
