Kite Photography - Rig 2

[andygates]

KAP rig 1 (Poindexter) was fun but very Heath Robinson, lower-tech than it looked and used an APS film camera with all the obvious drawbacks (mostly in speed of "wow"). Now I've got a digi and l33t skilz, rig 2 (Fat Charlie) needs to be built. The design is more compact and less wobbly, but needs bits not found in the average cyclists' shed.

Where do people buy their small engineering / robotics project bits from these days?
