CoralspeQ Prototype 1.5 Update – Ready to go for the field test!

Hey guys – another interesting update from Atsuko about the CoralspeQ, currently raising funds for early stage testing on corals.  MultispeQ V1.0 updates coming soon, till then enjoy! — Greg

Now the CoralspeQ PT 1.5 is complete! As you can see, it became a bit of a monster (compared with PT 1.0 right next to it). Inside, it houses a modified electronics board from MultispeQ, light sensor, and heavy-duty rechargeable AA batteries (that‘s right! They are no longer AAAs!).

We did our best to water-proof it– PVC glue is permanent, and silicon glue attached to the light guide and the fiber cable for the light sensor is impressive. A magnetic reed switch is installed inside, and you can turn on and off the instrument from outside using a magnet. Both Geoff and Robert are telling me that it has been sufficiently water-proofed. But as Dave Kramer pointed out, oceanographers have been working hard to figure out how to water-proof their expensive equipment. There is a reason why those water-proofed cases/ vessels are expensive. The ‘proof of pudding’ is in eating it. At one point in the field, I will hand this to a diver, and we will find out the truth.

We still have to open the box to recharge batteries. The PVC lid is replaced with a Plexiglas with gasket to increase the sealing capacity. I know it does not look pretty, but we are just being ‘MacGyver’ here. As long as it works, we are happy right now. There is a saying among us, scientists who do instrumentation (making own instruments), — if the instrument breaks right AFTER you took the last measurement, it is ok.

I am leaving for Hawaii this Saturday, Dec. 5. Dr. Ruth Gates, a coral scientist at Hawaii Institute of Marine Biology, kindly agreed with my visit for the field test. I am looking forward to meeting with her team.  I am going to post my blog on Google+.

Stay tuned!

PS – And don’t forget you can go here to support the next version of the device to help us better understand the coral bleaching process.
