High-Res Monitoring Solution: Low Cost Semi-DIY project

Carlmart -- Actually, the screens power connector is pretty fantastic. It's an L-connector at the bottom left of the Lilliput and very sturdy. Never had an issue with it. My issue right now is just figuring out if I can compact this setup anymore, and still doing a hunt. Another member (Bob Hill) is helping with a different sort of battery setup and we'll see how that goes.

bwest -- S-video is definitely a better signal than RCA. Whether or not you can perceive that is the question. I'd have to go and find the link to where I got mines from, I haven't tested it just yet either. I've tested S-Video out to the Marshall and it's better than RCA for me. S-Video from my Gamecube is better than RCA. =P So, I'd assume that it follows through all video components.

Zak -- Glad I could help! The thing is, I hope that it'll work for you the same. Please make sure that you purchased the Lilliput 619GL or 629GL as those are 16:9 800 x 600 Native resolution monitors. The others aren't so hot.

I got an order confirmation about the shorter D4 cables! Looks like they're sending them out and I might already have them at work if I can recover and actually GO to work.

Please show me how you've put it all together in the end, I'd love to see it!
 
By the way, we have one report from Siniarch who says that he didn't quite like this similar setup.

Second one comes from me, my personal experience is that it's a pretty good solution AND alternative to more costly items (Marshall, Ikan, ToteVision).

Another one is on DVinfo and the guy stated (Check my first post for the link) that he's using it and loves it.

So when you do it, please come back with your experiences. DVX or HVX, so that we all know what this does, can do, will do, won't do.

I'll take pictures of the Xenarc and Lilliput side-by-side and in action when I get the second monitor.
 
Hi all,

Batteries, batteries, batteries. I am putting together some documentation to help DIYers put together either NiMH packs or LiIon but I have a couple questions to ask. What voltages need to be supported and what kind of connections are needed? I know Kholi's rig needs 6V and 12V but I don't know the type of connector for the component to VGA converter or if there are any other voltages that need to be supported. In the meantime here is link to a good supplier or NiMH and LiIon/LiPolymer batteries chargers and supplies:

Thanks for chimin' in, Bob.

Got the D4 Cable, it's crazy-short! A+ Material.

And the Xenarc came in at the same time so will update with pics soon. Xenarc looks SWEEEETTTT.
 
Hey all,

I've been trying to work out an economical, powerful and lightweight battery solution. We all know how li-ion is the obvious choice, right? Well, Lithium Polymer is even better - an advanced version of Li-ion, being much lighter, smaller per Ah and it seems, the same price or less??!!??

The Xenarc screen, which is very very good, by the way, will take voltages of 11v - 24v, with a power supply input marking of "DC12V 1A" The included power supply puts out 10 - 13.5v 1.5amp max 15watt max.

I have found Li-Po radio controlled batteries rated at 11.1volts with 4Ah -7Ah capacity for very cheap on eBay, and they say "continuous current 35Amps Burst 44Amps" but my question is this: Will they output too many amps and blow the monitor, or is this a maximum current pull, with ampage being regulated by the device being powered? Somebody here must know how batteries work. This could be a cracking solution.

All the best
Lucas
 
Hiya Lucas,

Those Li-Poly batteries you are talking about are impressive. Your concern about the amp hour capacity damaging your monitor is not an issue. Amps are the capacity or amount of charge the batteries can hold. In the case of the batteries you are talking about 7AH capacity at 11.1 volts means it could power a 1amp draw 11.1V device for 7hours (this is very rough in reality) or a 2amp draw 11.1V device for 3.5 hours. That said, you probably want to look at the 14.8V batteries to support the Xenarc. Hopefully this answers your question.

Bob
 
Have either of you come across Li-Poly batteries @ 14v? 6v?

Those are the two primary voltages for the HD version of this setup. While you only need 12-14v (I was recommended 14v and it works fine) for just an SD application.
 
Thanks Bob and Zak.

Zak, you have to let me know how the battery works out cause I am not experience enough to do that kinda deal on my own. I might have to get you to build one or Bob.

You got PM by the way.
 
Zak,

Very nice. Having the PCB prewired makes life a lot easier. When you get everything together I would be interested to hear what you are getting for recharge times.

me neither. stayed up last night until roughly 4am learning more about electricity and voltage and wiring than i ever thought i'd need to know.

i'll let you know how they work out.

according to batteryspace.com, each pack will take about 2 hours to charge.

I actually went with NiMH batteries in a 2.3AH setup. They charge in about 30 minutes and they run my Xenarc or Lilliput monitors for about 1.75hours each.

Hi Bob,

Thanks for the reply. It wasn't the Amp hours I was worried about, as I know that this is the capacity of the battery, but the ampage output. If the battery states that it outputs 33AMPS continuous and 44AMPS burst, is this a) Telling us this if more current than this is drawn, the cables will overheat, or b) Telling us that if used in a 1amp device it will fry it? I think I know the answer now anyway. It is the former - answer a, right?

I'll get some of these badboys then. 14volt you say - right you are Holmes.

sounds good, bob. in my case, i didn't mind buying enough batteries to shoot all day. weight was my top concern because these rigs (i'm building two) will be used by my DP to shoot a 100% handheld feature. by day 20, she'll thank me. the whole thing should be just under 1.5 lbs if i'm doing my math right. the marshall i demo'd, with a battery pack, was twice that. maybe more.

Lucas,

What they mean is that you can draw up to 44amps for a very short period of time which is amazing. Very very robust battery.

Aw man. I can't believe this. The Xenarc has so many more features like image flip and flop which is GREAT. Anti-Glare, TouchScreen (I need this for an experiment I'm doing)... it's just got so many great things going for it--

The Lilliput 619GL just won it for me. It's got more options to correct the image as far as color goes, and renders motion better than the Xenar. It also has a better TOP viewing angle than the Xenarc screen!

And best of all... It's HALF the price! I got the newest Xenarc 700TSV 2008 version and I am about to send it back.

Now I just gotta get the Lilliput Touchscreen version to compare and I'm good, but this is truly astounding. I really thought the Xenarc would be a sort of "upgrade" to the Lilliput screen, and in ways it's better because of the ability to flip the screen...

However, I'm sold on the Lilliput and will be keeping it over the neare 400 dollar Xenarc screen.

Sick.

Oh and Zak, you got your screens fast! you must've gotten them from the same person I did! They shipped pretty darn quick and had good customer service!!

Edit here------

I may try out the Dynamix 8" screen as well. Will definitely be trying out the LIlliput Touchscreen as I have a specific application for touchscreen usage in the field.

Thanks for that. That might be why I think the Xenarc doesn't look as great, because it's Touchscreen.

That said, I have begun to check on the Dynamix 8" because I really want a Touchscreen to control a computer or laptop from book bag or remote location.
