Oh I read how he said it now lol it's early still for me! Hahaha

I've been lurking here for a few years, but for this I decided to sign up and post about the mindstream.
I'm working on my PhD in Oceanography at FSU right now, and work a lot with in situ fluorescence sensors, mostly cDOM, oxygen, and CO2.
Light at a specific wavelength hits a dye, causing fluorescence, which is read back on a photosensor.
I do apologize if some found the sheep analogy offensive. What I meant with this analogy is just like sheep not knowing what they are in for when going up the chute, all these folks talking about Mindstream have no idea as well, having never seen one or heard firsthand from a user about what it can do. We are in the dark, but people have all lined up with cash in hand heading for the chute. I do wish the company well and applaud them for being first out. This is a great advantage with new product introductions, and I'll repeat, A++ Marketing job.
Here's my bottom line.....Mindstream is going to cost $XXX.XX to purchase and $YYY.YY for yearly foil costs. Note I used X's and Y's because again, we are in the dark. I'm extremely happy with my wet chemistry test kits that have a fraction of the yearly costs, and find spending all that money on something unproven a bit bothersome. Now I say that having said in the past that I'd never spend the money on Vortechs, and I now own five of them....so go figure. Now where's the end of the line for that sheep chute? I need to get into it.
Actually they are not considered donations because you get rewards, Kickstarter states this in their FAQs.(keep in mind these are donations refer to your local accountant as to how to handle)

How much do those devices cost you?
Probably not the same price as suggest here, right? Hence the potential concerns.
In my experience, research grade equipment that caters to researchers who generally purchase their equipment with grant money or startup packages is often priced much higher than products that are aimed at the consumer market. It's a bit of a racket, unfortunately.
#6 How does the MindStream handle biofouling and things growing on it?
This was one of our most pressing questions, and were really concerned that any number of things could interfere with the function of the MindStream monitor. Thankfully, the MindStream has a number of features built in to it to prevent a great deal of biofouling, and to make sure the device keeps reading accurately.
For the bigger animals, the MindStream disc rotates back and forth almost all of the time even when it is not scanning its chemical sensors; this keeps snails and other things from climbing onto the disc, and it keeps pods and worms from getting under the disc where they are not welcome. Furthermore, there is a small brush built into each and every disc that gently wipes the photo sensors to keep it nice and clean, but it doesn’t really need it as much as you’d think because the whole unit is made out of a special “space age plastic”. Zeonex is virtually impermeable to water, and has 16 times less adhesion to protein – simply put, things can’t really grow on the MindStream monitor or disc even if they wanted to, not like other black plastics anyway.
Furthermore, the sensor pads are photoreactive, that is they degrade with exposure to certain wavelengths of light, and it is their color and fluorescence that is read by the monitor itself. Therefore the active area of the MindStream sensor discs is specially designed to reduce any stray light from reaching the working area.

Randy, not sure if you saw this:
Not entirely the total answer you are looking for, but definitely something to consider.
There are individual wipers installed on each sensor (according to one of the videos), but how well they function is really a matter of testing.
