April 23rd-29th
On 23rd of April we started the actual experiment of producing our first biostone. We used an automatic pump coded with Arduino to control the intervals and amounts of growth media to feed the bacteria working away inside the syringe.
The experiment ended on the 29th of April. The result was an uneven cementation, but nonetheless some solid, properly cemented pieces.
Flowchart, calculations and Arduino-code for the experiment is added.
