Following the accident in Totnes when I lost my Ixus, I bought a Pentax Optio S5i. As well as being quite a bit lighter than the Ixus, it also has an IR remote capability, so I bought a GentLED too. I'd acquired some Futaba mini-servos cheaply on EBAY so while rig 3 follows the same basic design as my other rigs, it ended up quite a bit lighter (550 vs 770 grams). The table on the left compares the two. Here are some pictures. Click on them for a more detailed image.

Notes:

  • the picavet, which has the WIDE shape suggested by James Gentle's research, is recycled from Rig 2 - it's still slightly buckled from the accident (but not as bad as it was)!
  • despite the resemblance in design, the only other components re-used from rig 2 are the 3 carbon-fibre tube legs, the aerial-support/pointing-stick, the pan axle and the battery pack (which works fine despite its "battering").
  • the pan and tilt servos are Futaba mini-servos. They have metal gears so they weigh 26 grams each, but that's much less than the 44 gram Sanwa servos of rig 2.
  • the shutter is triggered by a GentLED.
  • the wide gap in the camera frame to the left of the camera is to allow the video downlink module to be plugged into the camera.
