DIY Texting System For Really Underground Radio

Posted by timothy on from the nitpickers-will-come-out-of-their-caves-now dept.

Gulthek writes "Sixteen-year-old Alexander Kendrick has created a device that allows texting and other data transfer from almost 1000 feet underground. The tech could allow rapid emergency communication with the surface and opens the potential for scientific measurements without the need to continually visit (and disturb) the cave environment." There's some kvetching in the NPR story's comments that it's not the first use of cave radios, but that seems to miss the point.

    Even with low bandwidth, a simple message of "Hey, I'm still alive down here, send help" shouldn't be too hard.

    That's what she said.

    Yes, my "bandwidth" is "low"
