Blot Bot is a vertical plotter, built partly for a school project, which allows motors to move a pen to physically draw designs on paper.
The Blot Bot ecosystem allows anyone with stepper motors and a microcontroller to repurpose their hardware using Blot Bot's open-source software.
The organisation contains a couple repositories:
- Blot Bot has a firmware binary which can be flashed on to any Arduino-compatible board, such as the ESP32.
- Blot Bot also has an interfacing library, core-lib aka
bbcore, with many useful utilities such as generating drawing instructions and handling the networking between the firmware and the software. - To implement
bbcore, I am developing a desktop application which allows you to design and print drawings within a single app.
Information for specific aspects of the project can be found in their respective repositories.
The library bbcore, desktop app desktop and the firmware are all being developed for my A-Level Computer Science NEA project.
I have tried my best to decouple bbcore from the frontend, to allow any frontend such as a CLI to be developed around bbcore.
