I have become interested in trying to develop open source HPLC hardware/software, potentially for the release of designs to academic labs that aren't as well funded and do not require super duper high resolution or reproducibility of a ~70,000 USD brand spanking new HPLC (maybe for semi-prep or the most basic analytical applications, i.e. purity checks of single compounds).
However, I am really starting from scratch. I have recently acquired several old Waters 510 pumps and I have an Arduino Mega2560 microcontroller and a lot of will but not much skill (in this area). My first objective is to write a python program that will allow me to communicate with one of the pumps via serial communication between the arduino board and a PC. I am wondering if I should try and control the stepper motor directly with my own stepper motor driver board and power source or if I should try and use what is already in the waters pump. I am posting this to just start some discussion and if there appears to be any interest I'll keep you guys updated on the status of the project. This is probably the easiest place to start I imagine the detector and potentially autoinjector will be significantly more difficult.
