Ice Borehole Camera
Tests in Iceland 1999
This camera was designed as a first cheap prototype. It uses a small unit
which includes its own six IR leds for illumination on its motherboard.
The vessel was made using a stainless steel internal case (adapted from
a cocoa shaker!), a rubber-ring seal to a thick perspex window, held together
with an exterior plastic case bolted tight. A coax cable was used to lower
it and feed video back to a laptop equipped with a video capture PCMCIA
card. Six reflections appear in the image due to the lights being on the
inside of the window.
photo shows the truely gruesome nature of doing electronics on glaciers. The
possibility of treading on cables with crampons is ever present. The borehole is
visible on the bottom right corner as its water overflow makes a clean channel.
