For this project we are using the following projects as inspirations
| Project name | URL | Active/Not active | Notes - relevance |
|---|---|---|---|
| DIY spectophotometer | https://github.com/openscienceschool/di-lambda | Active | A modular colorimeter using LEDs as light source and a photodiode as detector |
| Flow-Through Photometer | https://www.hackster.io/alexanderkutschera/flow-through-photometer-0226cb | Active | relatively simple and effective flow through colorimeter |
| Peristaltic pump controller | https://gitlab.com/pcremades/peripump | Active | A simple persitaltic pump controller |
Moreover, we made a previous research on colorimeters when we developed our previous prototype based on IO Rodeo Colorimeter
