History: BREAD
Paper 1: Original Concept
BREADS builds on the original concept and guidelines put forward in
See original OSF repo for full BREAD v0 release corresponding to the original paper:
- Open source framework for a Broadly Expandable and Reconfigurable data acquisition and automation device (BREAD).
- This largely presented the concept of BREAD, many of the boards were non- or semi-functional or incomplete at time of publication
- This idea of BREAD was largely developed by Shane Oberloier and Joshua M. Pearce and implemented by Shane Oberloier, Nicholas G. Whismana, Finn Hafting, and others at the MTU Open Source Hardware Entreprise (OSHE)
OpenReactor
Before and following after this initial publication, the development of BREAD was done at MTU as part of OSHE and known new slices were prototyped and the MOST_OpenReactor software was created to create a more unified central controller with a user interface. Further developed by FAST Lab at Western University: OpenReactor, OpenReactor2.
Paper 2: Pyrolysis Application
As part of joint project with MTU and Western University and others for plastic to protein processing system. This resulted in the publication of the paper Modular Open-Source Design of Pyrolysis Reactor Monitoring and Control Electronics. The ESP32 thing plus C controller (ESPT) was developed along with more mature versions of DCMT and RLHT, primarily by Finn Hafting. The BREAD-Local-Software or BUTTER was developed by Finn Hafting and Xander Chin which used static web assets stored on the SD card in combination with the ESP32 asynchronous web server to create a locally accessible user interface.

Paper 3 + Thesis: Moving BREAD Towards SCADA
Further mechanical developments and applications to bioreactors and pH control was done by Finn Hafting and is reflected in the paper Moving the Open-Source Broadly Reconfigurable and Expandable Automation Device (BREAD) Towards a Supervisory Control and Data Acquisition (SCADA) System. The ESPT controller as since been discontinued due to its inhereint limitations in reliably handling more complex supervision and networking requirements posed by future development.
