Topic: Looking for advice: 7" LCD monitor? (Read 9373 times)

Hello,
I am looking for a 7" 16:9 LCD monitor, and since I am very new to the stabilizer community (I haven't even got my rig yet, still waiting for the manufacter), I don't know how exactly these thing work on a rig. I ahve ordered the MagiqCam 2P rig, just for the information. I live in Europe, so I am looking for a PAL monitor, which's AC adapter or charger accepts 220 V. I found two monitors, one is from Varizoom, second is from a company named ikan Corp, I believe there are more. I don't know how the ikan battery works, but the Varizoom battery is placed UNDER the monitor, I don't know if you can move it to the other side of sled. I guess that the sled could be too front heavy after that and whole rig would be hard to balance.
I think that the best for me would be to have a battery system like A/B or V/mount or best the NP-1, leave the battery on one side of the sled, and the monitor on the other side. Can you please recommend me a monitor plus a battery bracket that would work together?
I am sorry if this is a newbie question, just trying to get things working together and I have no experience.
Cheers,
Martin

This is what I did for mine, and some of the other guys here have had good fortune with this as well....
Go to mp3car.com and look under their "non-vga" listings. There are only a few listings, so look for the 7" Lilliput monitir. It is PAL/NTSC/SECAM compatible, widescreen-switchable to 4:3, and should be good for you.
I mounted a generic A/B goldmount to my sled. The monitor includes a 12v adapter, which I soldered to the A/B adapter to regulate the voltage from the battery to 12v for the monitor. That adapter plugs straight into the monitor. The base of the monitor has the standard size threaded hole so you can bolt it into your rig.
As long as you can solder 2 wires, and fabricate your own way to mount an A/B goldmount plate (whuch aren't that expensive on ebay), then you can have a good monitor within an hour or two of work.
The Lilliput monitor only costs around $130 dollars US.

Great! Thanks for the info. Can you also please specify more exactly which A/B mount should I use (with XLR output?) and how do I connect it to the LCD, which I assume has 2.1mm coaxial DC input? Few photos of the connection would be great, if that is possible.
Also, in future I would like to hook up video transmitters to work on the same battery as the monitor. They usually work for 12 V also, so what will I need, just some ordinary diverging device?

Most A/B goldmounts have an external 12v outlet for onboard lights. If you have someone handy with custom wires, you can probably have him make a short wire to fit the A/B output and terminate in an XLR. I'll follow up with some pics. My plate was actually a plate my station was about to throw out. It is off of a JVC. Anton Bauer has a generic goldmount plate which comes without any extra mounting plates (just the plastic portion you will see in the pictures).

I have not outfitted my sled with an XLR yet, but you will see what I mean. Just found out my camera battery needs charging....may be a couple hours before I can post pics.

If you describe to me how you are going to mount it to your rig, I can research it and tell you which mount will best suit your needs.

Alright, here are some pics...
This one is of the plate mounted with battery. The monitor comes with a regulator built to regulate the 12-16v supply from a car, to 12v steady. One end of the adapter has a cigarette lighter power plug, and the other a 12v female plug. I cut off the cigarrette lighter power plug and soldered the positive/negative ends to the corresponding outputs from the plate. I hid the regulator inside the lower j-box and the very end of it hangs out of the box. The cable that plugs into the monitor is proprietary, and supplies both the video, audio, and power to the monitor. The output end is proprietary, while the input end is standard rca's for video and audio, and 12v f/m for the power(will take pics of the plug later).
The second picture is of the monitor and it's proprietary connection.
The third is of the proprietary cable wrapped around my post (the cable is too long when they send it) with the video plugged into my j-box, which then runs up the post to the upper box, and out to my camera.
The fourth pic is of the secondary output from the plate. A simple cable with one end fitted with an xlr, and the other end to fit this output, will serve your needs in pwering any extra 12v-14v accessory.
The fifth pic is my soldered connection to the Lilliput car (12v regulator) adaptor. The goldplates ae pretty easy to determine which receptacles are the positive and negative leads. On the plate here, the pos/neg leads are the outermost receptacles. I simply soldered the pos/neg ends on the Lilliput adapter cable to the corresponding receptacle.
The last pic is of the way I mounted it to my sled. Again, this was a used plate off an old eng camera. My two support rods are about 3 1/2" apart. I made 2 rod brackets, took the plastic part of te mount off the base plate and screwed the plate into the rod brackets. Then I just re-mounted the plastic portion back onto the base plate. If you order a universal plate from Anton Bauer, it will come minus any base plate/mounting plate. A universal goldmount will be a piece of cake for you to mount to anything with a few bolts, and to wire whatever you need.

By the way...the monitor sunshade (not really needed), does not come with the Lilliput monitor. I constructed it in 10 minutes from a 16" linoleum floor tile and some gaffers tape. It mounts to the monitor by some velcro tabs on the monitor and shade.

Excellent information here, Wade.
The AB system seems like the way to go, although the dedicated charger, the plate and the batteries themselves do tally up rather quickly. I'm not sure what I'll go with at this point in time.
I'm also unsure of which monitor to buy, and what to incorporate into my junction boxes.
By the way, have you posted a video of your stabilizer in action? It'd be great to see how it performs.

I've been trying to find an opportunity to shoot my rig in action, but I haven't got the chance yet. I'm trying to get the second arm totally finished, and find an interesting setting, to shoot a steadicam duel. I'll try and get something temporary up sooner.
By the way, my total cost on the AB stuff: $40 US
The batteries I found on ebay (along with a charger I am now buying for $20) for $10 a piece. They are AB digital Trimpacs. The plates I got from my TV station, which was about to throw them away. I got them for free(helps to have friends in the business). The monitor I got from mp3car.com for $130. The only other cost for the AB setup is a $10 soldering iron to make the connections. Piece of cake! I'm sure you can find a used universal goldmount on ebay for a good price. Try it and see what you find!

And as far as what to incorporate into your junction box, I'll send you a link that has a wiring diagram for a 12v/24v/auxiliary setup, and a list of what connectors you'll need.

Good show, Wade.
Give me a couple days to digest it all, as I'm in the midst of new years festivities...

..... Martin, just an aside, but not that the mount from bh is the newer style release vs the older style in the second link.... |
