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.
