Although the drive updates and cooling works well one problem we hit into when installing them into the client's facility was that initally we racked the computers with the DVD drive on the left hand side (and hence the motherboard upside down). After about thirty mins of operation the Pyro firewire cards (see entries from Jan 2004) got very unreliable under the Avid application (which uses it's own 800mbits protocol called flame thrower) but from Windows all was well. Eventually we flipped a machine and all came good - must have been the additional vibration of the drives and the fact that the card had gravity working on it.

We have several world-class software developers here at Root6 - our tech director James Clarke has done a real job on logging for reality TV shows in his Ultra application. He's extended it to take in mobile picture blogging and if you go to Atomic Lava (link in the right hand column) you'll see the application being used to blog the engineers thoughts and pictures snapped on their 'phone cameras. If you click FunkyWorm you'll see what I've started to blog, and if you click the photos from my SPV click you'll see the Flash viewer that another colleague Nick Ridley has written. All very good stuff since the photos appear on the blog within minutes of you clicking "capture" on the 'phone.

Petra asked me to write a little note re the cheaper Avid products and IDE drives.
Chris was integrating an ExpressDV machine last week with the intention of having the media drive (250gig IDE model) on the same IDE channel as the system drive. The BIOS on that machine would only allow for one DMA device on an IDE channel and so the media drive chugged away at 33Mbits per sec (shows up as a PIO device in the device manager). Performance with 25Mbits DV media was somewhat jerky!
Now I know it will often work (on motherboards that support multiple DMAs on the same IDE channel) but it isn't best practise to try and get away with it and since another IDE/PCI adaptor (ATA 133Mbits spec) from Lindy (including cables!) is only £19 to us it seems that is the best way to go.
If the motherboard of the machine in question has Serial ATA ("SATA") then an SATA drive as the media drive would avoid this problem. However, SATA drives are currently about £100 more expensive than the same sized IDE drive and so the Lindy solution still saves us a bit.
The Lindy part number is 70642 and there is a price break at three pieces. I have put three cards in Pete's cupboard in accounts,

We have to supply nine of these top-end dual P4 machines to a client who needs 300gigs in each - the new 15k Baracudas from Seagate are out and so four 73gig Ultra320 drives seemed the answer:
Move the system IDE drive to the same bay as the DVD drive - you need a bay-adaptor (Lindy part number: 40545) and then mount the drive cooling fan kit on the side of the four-way drive bay (Lindy part number: 40517). Finally you need to remove one of the onboard SCSI ports from the back of the machine and run a terminated Ultra320 cable to the new drives from the mobo SCSI adaptor - Adaptec part number 1490826-00.
A few cable ties to tidy and a few hours of burn-in testing to ensure coolness and stability and it looks like we're good to go!

Suggested by my colleague Rupert (see his dead blog in the right hand column!) - of course proper engineers like me do dB calculations in their heads!

Chopper joined us later and we had a jolly time getting it all talking! SPV pics here.
Oh, Graham and I did spot what was clearly a production model of a Blue-Ray disk recorder (50 gig re-writeable disks) - clearly a domestic gadget from the far east - all composite video i/o (on phonos) and unbalanced audio. There are a couple of bad pics of it on the previous link.
If you're comming to the show then swing by the Sony stand and get Graham to give you the Xpri/HDCam religion - I'll be there on Wednesday.

The 1604 is a popular mixer in Avid suites because it has loads of facilities (lots of channels, auxes, four groups etc.) but they cross-talk between the two track return and the mono input channels. Today I was in a suite and there is a lot of bleed at only 35dBs below if you are using the 2TR return button to listen to the output of the Avid and at the same time digitise via the mono-channels and stereo bus you get an awful lot of cross-talk. Putting a balancing box in line with the 2TR return sorted the problem so I assume the bleed is back out of the 2TR input.
