Today I confirmed that the PurePath development board fits into the used radio buoy shell we acquired from a local tuna fisheries company. After the first range test with the PurePath development kit I decided that we need a range extender. Instead of using a generic 2.4 GHz booster I ordered one of the new CC2590 range extenders from Texas Instruments. If this 14dBm output boost is not sufficient we'll either go for the CC2591 (+22dBm) or add a generic 5W booster.

I was curious how the solar garden lamp managed to light a led using a single 1.2V rechargeable battery. Can you guess from the oscilloscope image?

We're using a COTS 2 Watt wifi booster for our first prototype of the whale monitoring buoy. We'll probably need a more powerful booster for final deployment.

These are the first pictures of our new underwater camera housing prototype. Now I have to fit the electronics into it and then we're ready for the test.
