loose express card

Thank you very much! two very useful links, this is the adapter I need and now I have to find one http://en.wikipedia.org/wiki/File:Ca...rd_Adapter.jpg

I have been using heavy tape as a strain relief for now but it's kinda annoying that the card wants to come out that easy.

I just don't want to use the small 4 pin jack on the laptop as I'm sure I will wear it out with all the fast connecting and disconnecting, when we go live via the net it's always a rapid deployment. I am trying to build a complete kit in a Pelican 1610 case with everything inside including power connections and everything.

My laptop (newer)for using wirecast for live streaming news video on the road is my Asus G50v and with 2.53G processor it's the video is still not always smooth and maxes out at 100% sometimes, works perfectly everytime when we are testing it with engineering just not when we are playing for real at an event.

my Older Asus F3 series is my desktop right now as I don't think it can run this Wirecast program, it's high end near broadcast quality video streaming but wow does it use resources.

Most laptops I've run across have ExpressCard/54-capable slots, and so if your adapter card is of the smaller, ExpressCard/34, size, the slot will indeed appear to be too large. This wasn't too much of a problem for me when I had to use an add-on wireless card on my old laptop, but for your application where you have external cables attached it might be.



I'd suggest trying to implement some cable strain relief system to take the strain off the adapter itself, but overall it sounds like you're dealing with much heavier usage than either the card or the slot is designed for. You may want to investigate something more like a docking station that might have a greater focus on durability instead of trying to get everything squeezed into the small form factor of a mobile add-on card.

A couple options:

• If your laptop manufacturer makes a proprietary docking station that includes Firewire, that would probably be the best.
• If that is not available, maybe try using a Firewire hub with the laptop's built-in port, that may be enough to alleviate some of the stress.
• This product claims to allow DV capture over USB, if that fits your needs
• Don't be so rough on your equipment!

Good luck,

Addonics seems to be selling it. I've had good experiences with their stuff.

I don't see how this is going to solve your problem, however. It still uses the same ExpressCard/34 form factor, and it seems like it would carry the same problems.

I see that now, I guess what I need is a spacer of some sort that fills all that empty space in that slot that is not used by the small express card so it has no place to go, at least not sideways and at the end of the day if I can't find one then I may just have to make a more solid and permanent strain relief for the cables as I build this kit in the Pelican 1610 case, that's probably the safest way anyways as that way accidents can't happen.


Thanks for that link, I'll look around their site.

Mark,
It would seem from first glance that strain relief tied to the underside of the laptop would be the way to go. Replaceable cable tie wrapped to the underside of the laptop would keep things neat while in the case and easy to replace when the cable has been overstressed. The cable will then also keep the card in place. You might even be able to add a loop in the cable then tie wrap to the extender/adapter and then to the bottom of the laptop to lock everything together. I am always one for having spares so if you are going to keep the laptop I would look into having a spare card slot (they usually just plug into the board inside the case), a spare cable and spare card adapter. If the laptop needs to sit on a flat surface, add a few stick on feet. You can get a variety from any hardware store.

That might be the route I end up going, some form of strain relief for the cable, probably the best way to go anyways in case of accident such as me tripping over the cable or something. I was surprised as how loose fitting the express card is though, it barely holds and that's on both machines and trying different cards so I guess that's just the way it is.

The slot is wide like the old PCMCIA slot but only small connector at the bottom and when you insert the express card it can go anywhere it feels like it.

In addition to the strain relief, if you're still looking for a spacer, you may be able to make one out of the plastic spacer "card" that comes with most laptops. There's also several ideas of varying severity posted in this forum that may be of interest to you.

Mark,
26 pins just doesn't hold as well as the 68 pins of the PCMCIA cards. With all the slop in the card slot, in your application, I can forsee some intermittent problems down the road if you don't come up with a solution that locks everything into place. I like the velcro solution in Ryan's forum but hate it on the control surface. It is just too ugly for me. Velcro applied underneath might be the way to go. I also like 3M Duallock which is more positive and won't let go when you really need it. It is available most places you can get velcro.

I looked at the pics in that forum and I think that's the route I will go, I really like what I see in those pics.

Thanks for the help, I am in Toronto, Ontario and I "thought" 3M Dual lock would be available everywhere well I think I looked everywhere and I couldn't find it, eventually someone who is into ham radio and electronics posted that this store has is and sure enough they did and I immediately bought a 5 metre roll of it

Here is the info on the store up here that sells it in case anyone else needs it:

www.noahsmarine.com
54 Six Point RoadEtobicoke, ON M8Z 2X2, Canada(416) 232-0522

Now I just have to build everything, it got so busy in news, 18 hour days and all I have a lot of spare parts for things that I have picked up over the last couple of weeks but no time to install or build anything yet.

Went exactly this route and it works perfectly, I did add one wrap of 3M industrial grade electrical tape (home depot) and it helped that card fit rather tight and the dual-lock locked it in and it hasn't moved yet and those of us in news especially setting up live hits five minutes to air are not known for being to gentle with equipment.

If the express card was a bit thicker it would have a chance of holding but these things just don't hold at all.

This fix has held good, now if only fixing the live video streaming issues I have were as easy.

thanks again,

Hey, it could be worse....

Leave it to Jim to bring up the good old days when TV production used TV81 http://www.tvcameramuseum.org/camera...v81a.htm#notes The days of iron men needed to pull this cable for each camera are long gone. The connector in the link is about 2.5-3 inches in diameter and the cable came on powered reels in the belly of the truck for sports trucks. TV81 cable is 1.75 inches in diameter and a single person could only carry about 100' coil on their shoulder. Of the 81 wires, there were six coaxes and several power wires carrying 120 volts or more depending on the camera. The wire had a 1/8" rubber jacket which made it even heavier and sticky when pulling or coiling the cable.

It's important to let the younger folks know what they're missing out on

One interesting (to me) pic on the page I linked to is this bus....



A friend just bought one of these old Flxible buses. his was originally a California Juvenile prison bus, then a church bus, then converted to a motorhome....

Sorry about all the old stuff, but I've been working on my 59 chevy pickup again

Jim,
The facility I worked at in Peoria while in school (Bradley U) had one of those Flxible mobile production facilities. It had been donated by WBBM in Chicago to Bradley and had three cameras, about 10k feet of TV 81 and two RCA quad video recorders. We stripped it to use the machines and cameras in the studio. The video department later became WTVP, public TV in Peoria.

since we are here in broadcast world.......

Al, do you have any experience in editing AVCHD versus P2 ???

My impression (and these are very very generalized statements) is that AVCHD is very popular for ENG, has a more progressive compression scheme and is 'h' 'e' double toothpicks on editing systems when doing HD. Basically you need an Intel i7 with multiple SATA disk channels.

And P2 is less rough on editing in terms of processor requirements but is used for professional 'hollywood' productions because of other superior image charactistics. The main downside to P2 being the memory is very expensive and the files very large.

dreaming of
Panasonic AG-HMC150 AVCHD type
Panasonic AG-HVX200A P2 type

when we find our pot of gold at the end of the rainbow.....
