Make Water - Collaborative Water Purification

Advancing DIY Water Purification
with Students & Citizen Scientists Around the Globe.

Similar projects worth following
Water coagulation plays a major part in large scale water purification processes.
We're fascinated by the potential of electrocoagulation for its simplicity, reduced environmental impact, and economic value. We designed coagulator kits so students and citizen scientists can learn about coding, 3D printing, chemistry, teamwork and philanthropy all while helping humanity unlock the full potential of this process which we believe can empower people around the globe to solve water challenges.

Electrocoagulation is process which utilizes electrolysis to bond pollutants in water until they are large enough to easily filter out.


  • Study & develop the electrocoagulation process collaboratively using DIY Open Source methods.
  • Activate and engage students and citizen scientists to participate.
  • Evolve the coagulator kits to simplify use and add data logging & sharing capabilities.
  • Share our progress through videos on our youtube make water series.

Thank Yous!

A big thank you to Les Hall. We wouldn't be this far in our project if it wasn't for his guiding light and mentorship. He introduced me to arduinos, 3D printing, and coding. He was there since the beginning when we had this idea to make small manageable coagulator kits for others to use and test and learn from. Hackerspace

    Lets make a coagulator!

    Make sure you have all your parts ready.

    1x 3D Printed Coagulator Lid - 3D File Link

    1x Mason Jar 16oz

    2x Electrodes - Type of metal is really up to you but we tend to use one aluminum and one iron.

Updated the files for the new coagulator kits using ludus boards and arduinio UNOs. Still need the 3D printed case base file.
