Thank you very much John for such a detailed description. There are some points that are interesting for ours.
Our mobile node will be used... everywhere. Actually we are thinking in a 3 projectors setup. Buy 3 portable screens.... The main goal is to reduce the size of the rack (that means to reduce every item we can think of), and try to work out some solutions for an easy .. "plug and play". The cables issue is a big one. We need.. room node quality equipment.. that we can move around easily. ----- Original Message ----- From: John I Quebedeaux Jr<mailto:[email protected]> To: Natalia Costas Lago<mailto:[email protected]> Cc: ag-tech<mailto:[email protected]> Sent: Wednesday, March 30, 2005 10:12 PM Subject: Re: [AG-TECH] Portable AG node Natalia, I hate to say it this way... but it depends. That's one of the things about the AG is that it IS so flexible for the environment you are putting it into. Will you use the portable in a small room, large room, auditorium, etc? everywhere? I'm currently upgrading our portable node and putting as much flexibility and power into as small a box i can get was one of my dilemmas. I'm still looking at motherboard slot configurations, etc. I'm going to be trying out one of those quad-capture cards... However: this is what my current portable node looks like below (LSU's portable node is affectionately named "Wilbur the PIG") two 15" LCD monitors one dual head AGP Matrox card (I forget which) one quad head PCI Nvidia card (I forget which) two Canon VC-C4 cameras one Sony EVI-D100 camera 3 tripods wireless keyboard and mouse one trackerpod quickcam (WDM) for operator three osprey 100 capture cards on board audio/network (100mbit on this one) CPU is a dual 2.2 xeon running XP(SP2) XAP400 one wireless lapel mic i borrow crown mics from my full node as needed for inputs 2-4 pair of genelec 1029A speakers surgeprotector/filter 50' to 100' of just about every cable - well shielded s-video cables btw. my upgrade will speed up the CPU/motherboard, replace the video card with a single quad card, put in a single capture card, have audio and firewire and gigabit. I'm going to add a 2nd wireless mic (for audience on a stand) and a couple of table mics I can attach. I'll upgrade the cart - pneumatic tires probably or build a split "cart" where the top and bottom are removable for easier travel in vehicles. I've taken Wilbur all over the state. Fortunately, this design fits in the back "well" of my van (where the back seat folds up into). Note, the tripods do fold up small enough to fit inside the cart. EVERYTHING fits on the cart. The bottom half of this card holds ALL the cameras, cables, etc. The top half holds the CPU, echo canceler, wireless receiver, monitors, and speakers (velcro holds them in place during the long rolls across campus). There is even a plastic cover (see picture with umbrella in the corner?) that keeps it dry in the event of a sudden down pour (which has happened... it's Louisiana, thunderstorms happen). =) The reason for the mismatch on the cameras is that i ended up with a spare camera from another project... and two cameras is NOT enough. I'll even say 3 isn't, but 3 is okay. The cart is a rubbermaid cart... we removed the drawer section in the top half, put a plywood board in for more support (that CPU is heavy), and cut one small hole for the cables into the bottom half where we have a powerstrip/surge protector. Hope this gives you some ideas. Basically though, this has allowed most of the flexibility I needed - I have a spare projector but it's not that bright and i have to rely on the installed projectors in rooms I go to, but 1 projector isn't enough (no one seems to understand that until they see our full node in action). They keep wanting to squeeze everything into one screen. Argh. Terrible. -John Q. _____ _____ Roll 2 - 1397 _____ _____ Roll 2 - 1396 _____ _____ Roll 2 - 1390 -- John I.

We are in a new stage of AG deployment, our new challenge is to develop a mobile AG node. It's a room one, but we need to move the equipment wherever is needed. And, we are in a hurry, as we need to purchase and have it working properly for an important event soon. I've seen this isnt a brand new idea, there is a pic of one "portable ag node" on the Internet2 website, and there are more sites that have one. The problem is that i couldnt find precise details about the hardware we should purchase. Or the better configuration (cable length, wireless video, maybe rack PCs?), there are so many choices!!. We greatly appreciate any suggestion, configuration and/or advices provided. Has anyone out there worked on a similar configuration? Thankx in advance, Kind regards, Natalia. ----------------------------------- Natalia Costas Lago email: [email protected] Centro de Supercomputacion de Galicia (CESGA) Avenida de Vigo, s/n Campus Sur 15706 Santiago de Compostela - SPAIN Tel: +34 981 56 98 10 Fax: +34 981 59 46 16 http://www.cesga.es/
