Earthed, wind and fire

Close, but not quite. Annoying, this.

This is a replacement solar panel for the one that fell off the boat a couple of winters ago. It's from the same maker, Kyocera, and it is the same form factor as the other three, but the flange to which the "rivnuts" (or "swage nuts", the terminology seems inexact) are mounted is about one-half inch more narrow than the older panels. The panel is otherwise identical, save that it delivers at peak output five more watts. Of course, the custom-built solar arch has hard-to-drill 1/8" stainless steel mounting tabs welded to the pipes, so I have been presented with a dilemma.

The old bits of tape were used to indicate where the two backstays transit through the arch.

Luckily, the man who is doing other fabrication jobs aboard, was aboard, and suggested we secure the outboard side with rivnuts as planned, and simply make up an aluminum 1/4" thick "tab on a tab" throughbolted to the existing stainless, and then rivnutted (that doesn't look right) from aluminum tab to aluminum frame. Pretty sure I can handle that job, and the galvanic isolation it probably wants doing.

There can be many versions, and I left a phone message today with a couple of further refinement suggestions.

Andrew was visiting the boat for an "as social as possible under the circumstances" reason, as well as further discussion on the fabrication of a pole for the Air-X wind generator I am finally installing to complete our renewable energy scheme, at least from the "watt creating" side.

You don't have to put out the red light...

Speaking of wind, I installed a Caframo "Maestro" 12 VDC fan in the galley. This involved drilling, wire-stripping, crimping, heat-shrinking and circuit-chasing, this time in the galley's DC subpanel. The fan has a bright white LED and a dim, red one, good for evenings, and its speed is controlled by a simple rheostat that clicks off.

I put in a little rocker switch, seen to the left of the pair of wires. The mounting plate of the propane sensor with necessary 3/4" hole for the mass of its leads is below.

Unfortunately, the rheostat appears cacked...it worked on the test run, in which I provisionally wire together the circuit to check for flaws before I dog down everything and drill multiple holes, and the light switch works fine, but it's "always on full" when attached to the terminal strips. I mean, I could turn it off, along with all the cabin lights forward, from the main DC panel, but that's just awkward. So I put in a little rocker switch from A1 Electronics on North Queen (25 cents, probably) and it works fine now. Still full on, but now with added off.

Yes, it works. I have a propane torch nearby for test purposes.

Mounting the new propane sniffer/alarm was a touch more involved as it required a hole through the cabinet (and cutting down some trim pieces and a hole through the bottom of the cabinet so that the sensor lead could go down to the front of the stove near foot level, where propane is likely to "flow" if we had a leak of it. Those wires will be cleaned up and mounted neatly later.

It's becoming a busy time. Eight days until it's home again.
