So thanks to the postings here and here and other forums I was able to successfully replace my battery inexpensively, fairly quickly and with not much drama.

I just wanted to add my two cents to the process in case it might help someone. Anyway, definitely read the other posts for details. My post here will be tips in addition. Disclaimer: I am not an electrician but I did take electronics in high school.

First thing is (in my opinion) there isn’t a way to open this device without damaging it. Even if its a small scratch or dent. I am guessing the reason M-Audio charges so much to replace the battery is they probably have to replace the back of the case which is the part that gets damaged and they have to cover any other costs associated with the repair. Possible accidents?

Second thing is you don’t have to dismantle as much as everyone says. All you have to do is remove the back cover. That’s it!

1. Buy an iPhone 2G battery (1400mAh) from eBay for less than US$6 (including shipping and tools).
2. Remove back cover.
3. Remove battery.
4. Here’s my big tip! Remove tape from top of the battery. Inside the white tape you will find a small circuit board. Take your soldering iron and heat the solder where the wires are connected to disconnect the black and red wires. Voila! Now you don’t even have to strip the wires!



5. Cut the exposed part of the white wire on your new 2G iPhone battery. Tape the end with electrical tape. I taped the small white wire to the end of the battery to secure it. Sorry! wish I took more pictures.
6. Solder the red wire from the Microtrack to the red wire on your new battery.
7. Do the same for the black wires.
8. Tape the exposed wires with electrical tape. I also taped the wires to the edge of the battery. Sure wish I took photos.
9. Tape the battery to the board. I used the old rolled up scotch tape trick. (Too cheap to buy double sided tape). Make sure the wires are away from where the case tabs align.
10. Plug the device in and test to see if it lights up.
11. If all is good install the back cover. Done!

Hope this was helpful.

Happy recording!

My wife and I just bought new phones recently and we just happened to shoot the same video at the L.A. Zoo today. I thought it would be interesting to show the comparison. Sorry for the large files but I wanted to show the videos as close to the original as possible. Also, this is not meant to be an “Apples to Apples” comparison. I meant to show what type of video you get with each phone shot in high def. The Evo does not shoot 1280 x 720 in H.264 (see original file specs below).

As far as I can tell, there isn’t a way to change video settings on the iPhone 4 but I haven’t researched that either. The HTC Evo allows you to change settings for white balance, resolution, encoding type, audio on/off, etc.

I don’t claim to be a video expert (far from it) but on first glance of these 2 clips the iPhone 4 video appears blown out initially. What might be nice is the camera does not have that “camcorder” type adjustment to lighting. Sometimes drastic changes in adjustments can be annoying. The video clip shot on the Evo seems heavy in the shadow areas but richer in color (maybe too rich). It did seem to adjust to lighting more like a camcorder.

Curious to hear your comments.

I just performed a successful blog migration for a client from B2Evolution version 2.4.2 to WordPress 2.9.2.  The blog I am speaking currently  has 577 posts and 33 categories and dates back to 2004.  In my search for a solution, I did find some useful tips online. Like me, you may have already found those pages and discovered that the solutions only work for B2EVO version 1.

Here’s the first page you find when searching google for “migrate B2Evolution to WordPress”: The (almost) complete guide to migrate b2evolution to WordPress (Oct. 29, 2007). On this page in step 2 you’ll find a link to a page that explains “How to Import b2evolution Posts to WordPress” (May 27, 2007). If you note the date of these articles you soon realize these instructions worked well on older versions. Don’t worry. This is still very useful information and I did use much of what was written. Note: Since the link in step 2 is now broken read the section titled “Import via Movable Type Export Format” (http://codex.wordpress.org/Importing_Content) (which has the same broken link).

Actually, I am reading some of the comments on the first page mentioned and there are some more current solutions listed there. This one looks promising: http://worth2read.org/blog/2009/01/31/import-from-b2evolution246-to-wordpress-27/. I ended up doing something similar.

Anyway, my goal was to do the following:

1. Downgrade the B2EVO blog from version 2 to version 1. (this is the hard part)
2. Export posts to Moveable Type.
3. Import Moveable Type files into WordPress.

Downgrading B2EVO to version

Before you begin BACKUP your database.

Things you will need: Access to a web server with MySQL and an installation of something like phpMyAdmin installed on the same server where your blog is located.

Go to B2Evo’s release history page . I downloaded version 1.10.3 title “Key West” (direct link). It was the last release of version 1.

Install version 1 into a new directory. You will only be using this installation temporarily.  This may be obvious but you should know the database structure is different in version 1 and version 2.

Exporting Tables From B2EVO version 2 in phpMyAdmin

From phpMyAdmin go to the following tables and export them in a SQL format. Hint: The easiest way is to set up an upload directory in the phpMyAdmin settings.

• evo_blogs
• evo_items > evo_items__item  (this data will be copied to a table titled evo_posts)
• evo_items > evo_items__tag (if needed)
• evo_categories
• evo_comments
• evo_postcats
• evo_sessions

Import your SQL files to B2Evo version 1

Here’s the method I used.

Note the structure of the table evo_blogs in version 1:

Delete this table before you import the SQL file. Import the SQL and then go back to the structure and match the old structure.

Follow this for the other tables mentioned above with the exception of  evo_items__item. For this one you will need to edit the SQL file. Do a find and replace like so: find “evo_items__item” and replace with “evo_posts”  then import the file and edit the structure of the table.

Anyway, you get the general idea.

Export Posts in B2Evo version 1 to Moveable Type

Navigate to your B2Evo verion 1 installation.  Your blog should be readable.  If you get an error related to skins go to the admin area and select a skin for each of your blogs.

Now you can use the instructions found here which involves:

1. Apply a new skin to B2Evo version 1
2. Download your old blog to text files
3. Import the text files to WordPress

If all is well, all of your posts and categories should be visible.  URLs to your images will be in the original location. I recommend keeping them there and then using the WordPress image directory for posts moving forward.

Read information on how to convert your permalinks here.

A quick note about the Rewrite rules mentioned there:

The one for categories…
RewriteCond %{QUERY_STRING} cat=38
RewriteRule ^index\.php /blog/category/Doing-business [r=301,nc]

… needs a “?” at the end so…

RewriteCond %{QUERY_STRING} cat=38
RewriteRule ^index\.php /blog/category/Doing-business? [r=301,nc]

Hopefully this is the last time you have to do such a migration.

Peace.
