Epic adventurer - Think steering, and kill switches

I built a more sturdy frame to hold the solar panels.

It sits quite low to the back half of the boat.. On my epic adventure, I'll add 4 extension tubes so that I can get under the frame and use the space (and perhaps even sleep under if), but when I just go our for a day trip, I'll leave the tubes off, and keep it low. It needs to be low so it can travel on highways on the trailer without shaking to bits, or catching too much wind. 

I'm mounting the entire assembly on hinges so I can lift one side at a time to add the extension tubes before I set off.  

The panels were originally going to be mounted on hinges as well so I could tilt them to the sun as required, but I figured I'd keep it simple and see how much cruising time I have per day without moving them. I can always add hinges later.

The frame looks a bit like this...

 (you might recognise it as my old aquaponics growhouse with some bits re-aranged), but I might cut some more bits off to shorten it a little. It's around 200mm longer than the solar panels, so the rest is just excess weight.

Epic adventurer - Solar fail-safe kill switch

I've been worried about all my dodgy electronics on my solar boat, so I figured I should have a master kill switch that couldn't fail, and came up with a fuse holder and a 6mm bolt, tied to some artfully arranged paracord in the form of a survival bracelet that my brother made for me.

Cut the threaded bit off the bolt, tie a nice grippy paracord handle to it, then put the bolt in the fuse holder that connects all the electrics to the positive terminal.

One pull and everything stops.

It should work.

If it does, I should also be able to clip onto it with with a 2m bungee cord when I want to move around the boat if I'm under way. That way if I fall off, the motor will stop. I think it's called a dead man's switch. I was originally planning to create one digitally, and I still might if it turns out to be a pain, but if I need it, I'll build it on the boat. If I did it digitally, I'd make a simple sonic tape measure with a PICAXE chip that would notice if I left my chair. Then it would beep in 60 seconds, then kill all power to the motor if I didn't wave my hand in front of it within 15 seconds.

I think I prefer paracord and my bolt fuse.



120 Things in 20 years realises a solar deadman's switch sounds like safety overkill, but I'll have junk everywhere, no side rails, and 2000km is a long way to chase a boat moving slightly faster than I can swim on the Murray River.
