get asked this all the time after i put a new vid out, so ill post some good for you guys:

here are links to where I get my goods:

here is a cup that will hold a camera on its own, but may vibrate a bit

here is the 'system' of cups/bars/clamps i use to mount out side and have no vibration

let me know if you need any other info...

 

lol, from the title i thought you ment cam as in 'camshaft'

 

haha oops, i should have been more specific LOL

 

got any pics of all this stuff mounted on the car

 

Hmm... where are you going to mount the valves, exactly?

 

here is an old thread with the one cup i used to use:

and attached to this post is a pic of the 3 cup setup with the cam facing the rear, not the best pic to see it , but all i have right now:

 

Very nice writeup Damian....I actually purchased one of the suction mounts and it works damn well....but I would like to get multiple angles of action at once.....the auto x cam is fairly expensive but you get great video footage if you have a dvr.....heres the link....

Auto X cam

 

hey scrub, i like some of those 'lipstick' cams, but a lot of my stuff ends up on DVD and I am spoiled with 3ccd camera quality, so until they come out with a hi res 3ccd lipstick cam, i will use my little 3ccd panasonics.

the nice thing about the lipstick cams though are they can be placed in really cramped spaces, so I may get one to shoot 'brake rotor' shots , or suspention arm movement shots, things like that.

 

Damian, is there any equipment that you can use to record multiple video streams on a single device; i.e. a hard-drive based device, or something equivalent to S-VHS ADAT where you can have multiple independent digital streams on the same tape? Something portable, maybe battery powered, and not extremely expensive?

I had looked at putting a lipstick cam in my grill and a couple other places on the vehicle but didn't want to have to mount several recorders and then figure out how to sync them all...

 

broken93, you ask for what I long for :-)

there are some high end drv liek this, but too much $$ for me to justify on small fun vids liek this, if you had a major project budget, then you coul dmake a killer system.

I am looking into using mini-computers with firewire inputs as recording devices, but nothign is exactly what i want, ... so i may have to invent it :-)

 

Okay; I once had an Advantech PCM-5820E SBC mounted in my car (in fact, I still have the very nice DC-DC reg'd power supply for it). There are newer Advantech models that are more powerful, and you'd just need to attach one of these on the PC/104 bus:

http://www.mangodsp.com/seagull_pc104.asp

That's 8 channels of composite or four channels of S-video plus eight stereo audio channels - OMG I bet that thing costs an arm and a leg! That plus a nice big 2.5" HD and you'd have all the video capacity you needed!

 

umm, thats a cool dealio,, ... but im not game for s-video... if it cant do digital (firewire) than its no good :-) hahahhah

i need that same board but with 8 firewire inputs :-)

 

Thanks Damian..............

I didn't realize that you had the actual CAMERA in all those places.........just some little lipstick type lenses.................

Dang............pretty cool.................

What is 3ccd...........is that high end digital, regular digital, or what?

Tks,

David

 

the stuff i work with is all digital, in miniDV NTSC format (720x480 resolution)

a typical consumer camera has one ccd, that mean one chip to capture all the image data.

a 3-ccd camera has 3 chips, one for color in the RGB color scheme, so one for red, one for green, one for blue....basically that means it camptures 3 times the image information of a 1 ccd camera, so the picture quality is better. Dont get this confused with resolution, that is usually based on the chip size, when i say better quality i mean color quality, saturation, sharpness, lighting, et.

...but since they have 3 chips they tend to be more $$ too, however all cams are getting silly cheap, my 3 ccd panasonics were under the 1K mark!!!! and they are very small for a 3ccd miniDV camera.

 

Well, here's a 3-port PC/104 firewire module:

http://www.mpi.ch/item462.html
http://www.globalspec.com/FeaturedPr...xhibitID=15488


I'll bet it's a lot cheaper than the vid-cap card, too!

 

ohhh ... ok now were on to somthing!!!


ohh but wait, ... i wanna know can it handle 4 firewire streams at once!!! :-)

 

This is the parvus unit:

http://www.parvus.com/datasheet/DS.a...t=LIT-0220X-01

Only $240!

 

i know nothgin of these kinds of cards? i dunno what pc 104 is? educate me?

also, i still want to knwo if it can handle all 3 firewire ports capturing data at the same time... can i read on that somwhere?

 

I've got to go for now but I will type up some info for you later on this evening.

 

thanks :-)

 

Alright, PC/104 is a bus standard, like PCI or ISA for embedded computers. The PCM-5820E is a Single Board Computer (SBC) that I used to have mounted in my car for data logging and such; it is an example of a "Biscuit PC" that has a PC/104 interface. The PC itself with hard drive mounted atop is about 4" by 8" by 3" in an industrial steel case, so it's easy to mount and very resistant to vibration, heat, etc. The case often has room and mounting points for one PC/104 card above the SBC. Most SBCs have no moving parts (no fans), which makes them a thermal nightmare from and engineering standpoint, but somehow they manage to pull it off.

Here is an example of a newer, higher-powered SBC:


http://www.advantech.com/products/Mo...=1-KOULO&PD=EC

A PC/104 "card" is usually an I/O device that works on the PC/104 bus. The neat thing about PC/104 is that the cards are stackable - to add to the bus, you only need one connector; the cards have a connector on both the top and the bottom.

PC/104 is a 16-bit bus by design. That's the smaller black connector; on the x86 architecture this bus is equivalent to ISA. The newer (top) connector in the pic is the PC/104+, which is a 32-bit bus equivalent to PCI. You would want to use the PCI bus for any high-speed data (like DV). At an 133 MHz bus speed, you get a maximum bus transfer rate of 532 MB/s, minus overhead.

I would put the figure at about 200-400 MB/s, depending on how interrupts are handled in the 1394 interface and whether the card can do DMA with three different devices simultaneously (it would have to do buffering). Depending on what options you have for formatting/compressing your digital video stream (I know nothing about DV or its bandwidth requirements), you may be able to squeeze all three video streams onto a hard disk at the same time.

 

great info... let me munch on this data a while and ill get back to you on it. maybe we team up and make a new product for the track community to capture multiple DV feeds or somthing like that.

 

Silly, RX-7s don't have cams....

 

The reliable ones do.

 

Damian, are you doing the split screen (upper/lower) effect in "post-production"? Have you looked into any system that allows you to superimpose speed or tach on top of the video feed?
