First of all, Gemeco's iNstall app is free if you already have an iPhone or iPad. Second, though aimed at professional marine electronics installers, some of its tools are valuable to do-it-yourself types and even just regular boaters...
In October I promised to eventually discuss the 3M Scotchlok IDC connectors I used to tap into Gizmo's engine gauge wires in order to install an Actisense EMU-1 Engine Monitoring Unit. Given that two experienced commenters already strongly dismissed these connectors for boat use, I did more research and testing. Tentative conclusion: while 3M does indeed state that Scotchloks like those tiny UY butt connectors above are meant only for 22-26 gauge solid copper conducter wires, they still seem like the fastest, surest way I've seen to splice the fine gauge stranded wires we often deal with afloat. Could it just be a mistake that's kept a lot of useful Scotchlok models out of 3M's limited marine line, or did I miss some major difference?
Perhaps, coming soon to a marine electronics store near you (though not yet online) is a fairly complete line of NMEA 2000 cables and connectors under the well-known Ancor brand. I particularly like how the kits and explanatory packaging will encourage consumers to set up their own small networks. The 2 and 5-meter cables, for instance, are sold as Backbone/Drop Cables, while the 10-Meter is simply a Backbone Cable (because a spur shouldn't exceed 5 meters). I saw the preview Ancor line above at IBEX, but learned more about it in a special Soundings Trade-Only advertorial publication designed for next week's METS show...
At first I was just going to replace the electronics panel at Gizmo's lower helm, but I got carried away. And at this point I've got a boat that I can't start -- because the engine instruments, and much else, are disconnected -- in a slip that I'm just bumming until the real occupant's yacht is launched (which accounts for slow posting here). But the project is going well, and I'm particularly pleased with the Azek expanded PVC board product I'm experimenting with for the dash panel(s)...
The average boater doesn't need a power analyzer like this, but battery scrooges and testers like me might be interested. This Medusa Research Pro is actually designed for radio control hobbyists but its features and value appealed to my inner geek, and so far I've been really pleased with what it can do...
There are numerous cable labelling devices and styles, as folks have commented about in the Gizmo schematics entry and the systems forensics saltwater pathogens entry (;-). I even have a low-end, but decent Dymo LetraTag Plus whose tape labels can be made work okay on cables. But last week I noticed, and bought, this newish Dymo Rhino 101, which can be used with self laminating cable labels. I like it; it's simple, light, and fast, and no batteries are required.
Here's a Gizmo plumbing detail that turned me on from day one: A hot/cold shower head plus salt- and freshwater outlets (with quick disconnects, yet) all clustered neatly under the fly bridge ladder, with hose storage. They're even labeled well! But, when I first fired up the freshwater hose to rinse off the cleaning work I'd started with salt -- the resources are limited where I'm tied up -- I got a funny feeling and took a taste...
There's an old thread at rec.boats.electronics on how to best install a plotter in an open cockpit so it can be easily removed. Sandy offered the interesting suggestion of using "finger cots" to protect the loose power and data plugs when the unit is put away. Finger cots? Well, hopefully I'm not completely naive, and some of you don't know what they are either? They are used extensively in electronics manufacturing, as seen above, and have other quite different uses, as discussed in Wikipedia. At any rate, finger cots seem handy for protecting plugs and handling circuit boards--and who knows what else--and they can even be found on Amazon.
Most Class B AIS units have an SRM/Silent Mode switch on their casing, but the ACR Nauticast B instead provides a wire to a user-supplied switch. The plus is that you can more easily mount the transponder remotely, the minus is that you do have to install a switch, or only use the included software to control the functions. Incidently, that same software (similar to this) lets you choose the switch function: either to go in and out of silent (receive only) mode or to send a SRM (Safety Related Message, so far little used). At any rate, longtime Panbo reader Dan Gingras—a known LED fan—built the handsome Nauticast B switch above, and has kindly shared his design…
Let me say right off that the delightful title above—antenna cables and connectors really are important to performance—is stolen whole from a first class essay on antenna cabling written by Jason Reilly. And the illustration is cut from another useful coax connector page by Edward Kuester. I don't want to be an expert on such matters, but anyone who fools much with VHF, GPS, AIS, TV/FM, WiFi, and cellular antennas runs into all sorts of semi-standard connectors, and often the need to transition from one to another. The links above are great for the nomenclature, intent, and limitations of the various types, but I don’t think I’ve yet found the best sources for all the bits and pieces I could use in the lab, and you might need on your boat.
