Prismatic is open-source software / hardware for photobiology research

What is Prismatic?

Prismatic is a modular, wifi programmable, multi-channel LED light that gives you precise control over the the spectrum you give your plants. Connect with your phone or computer, the web-based scheduling system lets you create simple and advanced programs.

I built Prismatic to optimize light spectrum for organogenesis and regeneration in tissue culture, but it can be used for any precision lighting, photobiology, specialty plant growth, or plant propagation situation.

Prismatic V2 Coming March 2019

Pulse: a multi-channel LED driver

A multi-channel LED driver built on NodeMCU (with constant-voltage and constant-current versions, depending on your needs).

intuitive wifi-programmable UI for programming advanced schedules
upload programs, replicate experiments

Photon: a multi-channel LED array

A 9 channel LED array designed for the WeVitro dogBox tissue culture bioreactor

Prismatic V1 AKA FinMax

How is Prismatic used?

Each Prismatic module can be independently programmed, try growing your plants under different conditions and see how they respond. Perform controlled experiments using the Central Composite Rotatable Design. Generate a response surface and find the optimum mixture of spectra. I then validate this using replicated studies.

How did I make this stuff?

Programming C, C++, HTML, and JQuery on NodeMCU
Circuit design Eagle
PCB fabrication www.jlcpcb.com
PCB assembly Made to order, assembled by hand in Guelph, Canada

What's here for me?
