McMurdo Smartfind S10/ Standard Horizon MX2100 AIS

I have just bought a Standard Horizon Marine VHF transceiver GX2100E which has an integrated AIS receiver. Lets see how the McMurdo Smartfind S10 Man Overboard AIS beacon looks on this in test mode.  This is a bench test and we are far from the sea. On the right here is the display with VHF channel, GPS display and the AIS position display






The beacon goes in to active test mode by turning the handle to test and holding it a few seconds. The strobe light flashes and I took it outside. After about 30s it acquired a GPS fix and the light goes in to a pattern of groups of three flashes







Here is how it looks on the AIS display of the radio. The MMSI of the beacon starts with 97 indicates it is a beacon (I am not yet sure if the MMSI needs to be registered on the ships radio (OfCOM) license or with the MCA as EPIRBS have to be. It did not trigger an alarm, but as it is in test mode it presumably looks just like a ship.



















As it has an MMSI the radio thinks you can call it. You can send a DSC alert but that will not do anything as far as I know.  The MMSI is built in the device, unlike radios where you have to apply for one and have it registered.

EPSOn DX5000 Gutenprint stripes

So my wife has an EPSON DX5000 inkjet printer. It worked fine on photocopys and printing from a memory card, but using the Gutenprint driver on her Mac it printed photos with lines or stripes on.

It turns out that in the print menu setting Printer Features Extra 2
Print Direction->Unidirectional and maybe Interleave to Alternate Fill fixed the problem.

Wife and daughter happy printing photos now.


I think the DX5000 is called a CX5000 in the US.

Nokia 97 and Google Calendar

I am the proud owner of a Nokia N97 - my new work phone. It immediately fixes some problems I was having with my old E51. I couldn't read the screen on the largest font size without reading glasses making me feel rather decrepit, Also it was absolutely painful to send emails on it.

Out of the box it works fine as a phone and email with the University of Manchester's IMAP email server. The big touch screen means I can even read email while walking. I have not got used to the scroll and would like a scroll wheel. The slide out keyboard is fine.

But my other problem is being in meetings and not being able to check my diary or add things to it. I use Google Calendar. Its great as I can just paste appointments like "External Affairs Committe meeting at on July 26th at 9:00 in the Council Chamber Sackville Street" and the google calendar parses it and puts it in the right time. Sometimes even gives a link to a map!.

Ok so how to sync with the N97? On my E51 i used Goosync. That was good but they have just made it a paid for service and I knew other people had got the N97 to sync with its own software.

First thing about the N97 you need to know is that Mail for Exchange is installed (you dont need to get it from the Ovi store) but it is integrated in the mail program. You have to set it up (with the wizard) to point at the server m.google.com. But if you just put in your google mail address it just sets up google mail automatically with IMAP. Well done Nokia/Symbian. Good thing to do. But then you cant change to an exchange server. So start setting up another email account. Put in any rubbish for the email address but be sure to type m.google.com as the server, your google name and password. Then you get to edit the settings. In particular when it has looked at the server and decided it is an exchange server you can choose Exchange rather than Imap. Now you can go through the sync options. I turned off mail, contacts, todo and turned on calendar. Ok so now I can see my Google calendar in the calendar app on the N97.

More when I have some experience of it working.

Thanks to UoM IT support for sending me a helpful link. Vodafone were willing to help but had no real experience of the N97. I spoke to someone called "John" at Nokia support who was very jolly and not called John. He was keener for me to rate him as 5 on the online survey than he was to help me. I called the special N97 help number he passed me to. The first suggested I send the link to the Ovi download from the Nokia site. He didn't have a clue. The second guy I spoke to did know that it was now integrated, and then I figured it out.

Cheap USB Camera 0c45:62c0 Microdia

The built in camera on my laptop bust and I had an important Skype call first thing in the morning. I was staying at a Hotel in South Kennsington so went out to a local shop to buy a webcam. Armed with my laptop so as to get one that worked with linux. Well specifically with skype. I run OpenSuse 10.3 on a Del XPS M1330. I tried a logitech quick cam before with only limited success so I was suspicious. However the Dell built in camera worked fine on everything: Skype, kdetv, Ekiga etc.

The one I bought says "Sunny" on it but is a generic chinese made camera. It has a ring of blue leds controlled by variable resistor on a bump on the cable, and can clip on the laptop or stand on a table.

On plugging it in lsusb identifies it as "0c45:62c0 Microdia"

After some fiddling, much to the amusement of the man in the newsagents where I bought it, I eventually found that running luvcview -d /dev/video0 -f yuv -s 640x480 managed to knock v4l and the camera in to action and after focussing I got a good picture. Skype did not have much to adjust once it found the camera. Not got it to work with Ekiga consistently but works fine with Skype and kdetv. Also not figured out how to get the flash plugin (eg facebook video) to work. Well I'm not the only one with that problem.

Cutting pages out of pdf files

Just discovered PDF toolkit. Makes it really easy to cut pages and do many other things with a pdf file in one easy command line.



Useful examples on Linux.com.
