not exclusively a mobo issue and definitely not an exciting one, but...

anyway since I can hardly move, I have lots of time to think and plan although I cannot even stay seated in front of the computer long enough... :(

My plan is to use VIMAR electrical stuff for the "wall" plugs and general switching.
Now, on the boat and particularly in the cabins, you mainly need a socket or two to charge mobiles, mp3/4s, cameras etc. Fortunately most of them are usb jobbies. So using my preferred series of VIMAR IDEA, in 6U assemblies, I can have ONE such for each cabin and have 2USBs, 2 6or10A 220V (of an inverter) and one 16A schuko (sp?) off the gennie/shore power.
I can get locally my 6-10-16A sockets, but not even the fcking VIMAR catalogue has an IDEA USB listed. I did find one company in the US providing them (check here) So first question, anyone aware of a place I could get them ahem, more locally? Vimar part # seems to be VM16368, but nowhere to be found???

Alternatively I was also thinking of adding a cigarette lighter socket in there, makes sense? I honestly think that the USB supersedes the lighter one but I may be missing something. Consider it or skip?

Finally, the most important issue is how do I drop the 24V to 5V???
Yes I know, a converter centrally and then wired to each socket but that means that the transformer of some sort in the converter will be live all the time burning juice for no reason whatsoever. I doubt there's something clever and I don't want to end up having to use a toggle switch with a tiny bulb to let me switch on and off each individual usb socket (and use a transformer behind each plug assembly!). Anything smarter?

I think the provision of usb sockets as charging points is a smart move (I wouldn't put the cigarette lighter sockets - what uses these nowadays? especially if you're providing mains voltage via the inverter). The Vimar online catalogue lists these as Idea/Devices/Socket outlets for signal reception. Have a look here and you can navigate to the usb sockets using the lh nav device. I notice the site is also available in Greek, which suggests there may be a local distributor?

that was quick and efficient! thanks a lot, I was looking at another "official" catalogue that's v.fancy, extremely slow and missing stuff as it turns out.

Yes, there is a local dealer, I can even order from Volos where I am now, although I started this thread early enough as I'm going to Athens and I want to place one order for all my stuff from there, should be cheaper...

Still need to find an efficient way of converting my 24V to 5V

cheers

Any good? 96% efficient...

cannot find the virtual pint gif/jpeg around, but I surely owe you one!

yep, that's just perfect, small enough, around 86% efficiency at Vin of almost max (28V I guess) but what's most important is the 2mA standby current!
Will have to check that 1A at 5V is okay, I guess it is even for the 8inch android tablet. That's what I need, will also fit nicely within the vimar enclosure and it's cheap!

Looks like I'm sorted, just getting the order right ;)

cheers

great Idea Vas,
good advice Jimmy,
thanks a lot,

coincidently I was just now browsing the farnell catalog searching for some digital panel volt meters :)
 
Keep in mind that some make USB chargers above 1A (since the iPad2 takes 2A to charge within fair time).
2A has proven helpful to other gear as well, although some simply sip whatever (lower) rate they're designed for.

If fitting cigarette lighter sockets you may combine with a flush mount USB and have the flexibility of both. Remember, however, that most cig. plug. devices draw several times the amps of USB's.

unearthing a 5yo thread just to warn that things didn't work quite as planned, SpiD above pins it nicely!

After two seasons with all sorts of mobiles turns out that lower end sonys samsungs, lgs charge fine with the farnell catalog sourced 1A jobbies.
My Xperia ZR and now XPro don't get enough juice to charge (just discharge slower :D )
Iphones 4 sortof works, 5 and 6 nada.
GoPro works (iirc)

So clearly an issue of not enough juice pumped out. Last season I swapped 2-3 of them for 1.5A Fernell droppers to no avail.

So now, considering I'm fitting 600W of solar panels on the hardtop, I'm thinking of been less worried on the standby current and get a few 3A 5V boards :eek:

ebay has a ton of stuff, however most small boards (without a USB female socket on, which I don't want!) specify input up to 28V. I wonder if that's OK, or I should go for the very few that accept input up to 35V. And I'm also slightly worried as these boards are going to be under power 24/7 as I wont bother turning power off to the 24V sockets around MiToS!

FWIW, they are all 3A 15W rated
If you ebay query "dc to dc converter step down 5V 3A" you'll see what I mean.

Looking forward to your suggestions as I'd like to order soonish and have them fitted for summer :D

cheers
