I've been a busy boy these last couple of weeks modifying and customizing a batch of GoPro Cameras incorporation wireless remote control and 2 types of delay timers in preparation for filming the Hamilton Island Cup. As i will also be paddling in all the events, i need to be able to have most of the Canoe Mounted Cams turn on and record at different parts of the course automatically, except the radio control type which will be controlled from the support boat.
This is what i have so far.

After Hamo, I'll post full construction details of these mods including the disassembly of the GoPro and how well they worked. Maybe there's a few of you might be handy with a soldering iron as well as a paddle. ... hahaaa.

Help needed...
My gopro record for 10/15 mn and then switches off... could it be the batteries (Duracell) or the heat ? Did you ever had this problem ?

that is one sic set-up! Kudos to you for sharing that - regardless of what the outcome will be, I admire the passion and ingenuity. Hope u have an awesome race!

Hiro, Energizer AAA rechargeable are the only way to go, last me almost 2 hrs. Nothing else comes close, i have tried them all.
Also vibration could be a culprit, check that you have the updated battery case with springs both ends.
But most likely alkaline battery problem, they drop voltage very quickly. If icon in top left corner flashes after 15mins then definitely battery.

Thanx Rambo, so I'll buy some Energizers... It's silly I have a 2gb Memory card that can record up to 1 hour and the batteries last less than 15 mn !!!
Definitely a batterry issue : I used some Duracell ultra M3 and they lasted longer : 20-25 min... What is strange is trhat the camera won't work with them after that 25 minutes, but if I test those batteries, they still deliver 1.5 V ???

Guy's i think I've found a really good camera angle and perspective with the GoPro for Oc1. I'm considering having this as the No1 cam angle on a couple of the top Oc1 paddlers at Hamo.
What do you think?

At no load a typical battery will still read its nominal voltage value (~1.5V in this instance). What happens is that the camera requires a certain ampacity (load current) AND voltage value for it to operate. If the load current is a high value and/or is required for an extended period of time the battery begins to heat up AND you see a voltage drop across the terminals. A good example of this is the battery rating for a cell phone. You will notice that the specs typically have a "stand-by" rating (typically a period of days) and a "talk" rating (typically measured in hours). That "talk" time is when the cell phone is in use and as a result requires the most amount of ampacity (or juice or energy). It is during this time that you will notice that the battery/phone begins to heat up. This heating up causes that voltage drop and also drains the battery's ability to push out the required ampacity for nominal usage (as a result the cellphone dies).
It is exactly the same idea. You can see the ratings of batteries on a manufactures website and it typically shows how they perform as they begin to heat up (voltage drop and such).
