Want a working video

[yilinalinalin]

Hi Harvey:

So excited to see your work! Can I have a working video of it? So that I can better understand how to build the circuit and assemble the hardware. I'm going to use this to test the plant's chlorophyll, instead of the algae's.

Thanks!

Hi Harvey,
Echo what "yilinalinalin", I am interested in the study of both plants as well as algae. Thanks.
