I ordered all the parts. They should be here by the end of next week on Friday.

I got my hexapod kit yesterday! I put together the frame but I do not have the servos yet so I can't put the whole thing together. The servos will be here later this week.

I got the servos and assembled the hexapaod. I don't have a 6 volt batterybut I do have a 7.2 volt 1400mah battery. Would the 7.2 volt battery be ok to use with the hexengine?

The HexEngine will be ok, as there is a built in regulator, however, the servos shouldn't really be run at 7.2V, especially as when the battery comes fresh off charge, the voltage will probably be more like 8.0V plus!

You will need a 6V pack or a powerful 5 or 6V regulator.

I do have a 4.8volt battery but it's only 620mah. Would that be a better choice over the 7.2 volt battery? The run time would be cut short but at least the servos would be ok.

Yes, I would give the 4.8V pack a go, but as you mentioned you may find the run-time is a little short, also if the pack is not capable of supplying a high enough current demand, you may find the HexEngine resets its self due to a voltage brown out.

I won't be able to get the 6 volt pack until this weekend, so the 4.8v pack will have to do until then. The 4.8 pack just has to last long enough for me to try setting up the hexengine. Where can I get the directions for how to wire and program the hexengine to work with the logitech ps2 controller?

How should I check the continuity of the ps2 cable if my multimeter's probes don't fit into the holes of the cable? The probes are a little too big to fit in the port.
