550ex PC sync socket conversions

Where in the UK can I get my four 550ex's converted by having PC sync sockets installed?

    I've ended up using small hotshoe adaptors with PC fly leads to plug in to my radio triggers. Some on the market are too thick when using Chimera Softboxes.

    The voltage is fine. When I said < Some on the market are too thick when using Chimera Softboxes > I meant that they were too thick to use with the 550 EX's on the Chimera brackets. In other words the combination of these thicker hotshoe adaptors with PC flyleads meant they wouldn't fit in the aperture of the bracket and softbox ring. The thinner ones were no problem.

Merry Christmas Nigel and all,

Just make sure that the Trigger Voltage is under 7VDC on that adapter. Most likely it is because you're using a Canons.

If your are using them(580s) inside a those softboxes, you can use any flashes. They are lot cheaper than 550 or 580.

I do medical/photo equipment repairs & IR conversion, but I'm in the USA.
Over 20 years and Canon knew about that problem including many photographers. Most of Canon flashes can not do manual or aperture mode because they have to flash sensor.
Now they have it on the 580EXII. I guess Canon has no photographer working in the flash department.

Canon screwed photographers, buy a Metz, Vivitar, Sigma, Sunpak, or NIkon.

There is no direct method available as far as I know. Either sync you account via Imap, if all your emails are on server then outlook will automatically sync all your emails.

Otherwise you can use some third party tools available online. One such tool I am aware of is ThunderBird to PST Convert Convert Thunderbird Emails to WIndows Outlook...

Convert and Transfer Tivo/TS to iPad for HD 720p Playback I use the old version...

Convert and Transfer Tivo/TS to iPad for HD 720p Playback
I use the old version of Toast 8 with TiVo Transfer to download my favorite shows from my TiVo Premiere to Apple hard drive. However, I could not get the movies to my new iPad via Toast or TiVo Transfer. The file extension for the TiVo videos is not supported by iTunes. Thus, I need to convert TiVo to iPad compatible format.
Aunsoft Video Converter for Mac is the right TiVo to iPad converter for me to convert recorded video to a file that iPad can use. The Mac Video Converter for iPad does convert .tivo files to .mp4 for iPad. I like setting it up to convert my favorite TV shows and movie, and go to bed, leaving it working. Then sync them to iPad for watching on my travel.

For you guys who may have the same problem for converting TiVo to iPad MP4, I here demonstrate the quick steps using Aunsoft Video Converter for Mac.
Step 1. Load TiVo videos to Aunsoft Video Converter for Mac.
Run Aunsoft Vido Converter for Mac as the recommended Mac TiVo to iPad converter, and click the "Add" button to load .tivo videos or .ts videos, which had been transferred from TiVo Premiere to MacBook Pro or iMac.
Step 2. Choose iPad 720p output format.
Click the "Format" option and choose iPad > iPad HD Video(*.mp4), and the Mac TiVo to iPad converter will downscale the 1080i TiVo videos to 720p iPad MP4 videos.

Step 3. Convert TiVo/TS to iPad MP4.
Click the convert button under the preview window, and the Mac TiVo to iPad converter starts transcoding TiVo/TS to iPad MP4 in 720p.
After the conversion, the HD videos will be ready for syncing to iPad. With Aunsoft Video Converter for Mac as the TiVo to iPad converter, it is easy to transfer TiVo videos to iPad.
If you have TiVo videos from your friend, remember to ask for the Media Access Key (MAK) for the files. Click the Option button and enter the MAK before loading TiVo files for conversion to iPad.

Converting cafe range to lp

once you have the conversion kit, here is a simple procedure to follow to convert your range. Most conversion kits come with step-by-step instruction sheets. Also, use a piece of black electrical tape and fold it over the edge of the socket you'll use so that part of the tape is inside the socket. This will maintain a hold on the orifice when removing it so you don't drop it inside the stove top.
