Some good info there, Anthony

I can feel the irresistable pull of a monochrome CCD cam

Hi Guys
Just to butt in here. I bought my DMK21AF04 a few weeks ago and have just done a `free` firmware upgrade to the .AS version so can`t see where a price difference comes in?. I think they are both priced at 330 euros over here in the UK ie about £280.

Yeah, me too...

I have always wanted an answer to the questions I asked, now I have the answer...

So it's time for another question.

Anyone know how I can attach the cfw8 from my sbig setup to one of the DMK's?

Cheers
Stuart

cfw8 - colour filter wheel ?

If so what thread does it have.

[rat156]

Yes the SBig CFW8.

It's actually bolted onto the front of the ST-7, but I think that there's t-thread on the inside.

I have since realised that I can't control it without the ST-7 inline as well, so looks like I'm up for another filter arrangement.

Cheers
Stuart

Yes, the AF04 and AF04.AS cost the same in USD.

This afternoon was frustrating for a while after I finally got a firewire 6-pin PCMCIA card. I was also having initial problems powering the camera with the firewire PCMCIA card, but it turns out that the included supplement power (via USB cable with a power plug on the other end that plugs into the card) is insufficient at only 5 volts. I crossed my fingers and plugged a wall outlet DC transformer into the card that is set to 12 volts. The camera was instantly recognized. I turned down Windows attempt to install a generic driver, and installed the supplied driver. Everything works just fine now, so I'm eager to give it a first light.

For the record, my laptop is only a 667Mhz/256MB computer with a slow 4200rpm hard drive, and it dropped zero frames @ 30fps and Y800/unspecified.

Nice going Justin. I had a few problems as well, getting it up and running reliably. (see DMK - Connectivity issues)

I also gave 60fps a try using Y800. The live window was choppy and froze at moments, but the actual avi was smooth and dropped no frames. It is doubtful I'd use that framerate on anything except maybe the Moon.

Kind of amazing for this little VAIO C1VPK laptop since it only has an 8MB 256bit video card. A lot of DMK users said I should upgrade my Win2K Pro to XP, but that would just consume more system resources.

So overall, a PC with stats like mine is the real bare minimum for these cameras.

5 volts? Hmm, the firewire spec is 9 to 30 volts @ 2 amps, so no wonder the usb port doesn't cut it - I think it's 5v @ 0.5 amps.

cheers, Bird
