iPhone 3G buzz....

After having read some of the discussions on the previous post, I think it might be good to speak some sobering words and try to see things in perspective.

• The new iPhone is extremely cheap, even cheaper than an 8GB iTouch..... BUT you will have to sign a two year contract with AT&T (see here) for most likely a minimum of $39.99 a month.... or sign and then break the contract and pay the termination fees (probably around $200). So that puts the price tag right back at $399. My guess is that AT&T is subsidizing Apple those $200 for every phone sold.
• AT&T is still the exclusive U.S. carrier...
  
• Rumors are going around that you won't be able to buy an iPhone without signing a contract, either in the Apple Store or the AT&T store (see here)
• Regarding the iPhone 3G itself, how many of the current iPhone users would actually upgrade to the new model? Most likely those users who are already with AT&T and who are willing to spend the additional $199. I would guess that for most of the hacked phone users (who don't wan't to be with AT&T to start with), dishing out $199 + cancellation fee would be a little over the top.
• Steve mentioned that around 6 million of the original iPhones were sold. It was estimated that around 750,000-1 million phones were hacked at the end of Jan. 2008 (see here) and maybe it is even up to 20-25% now. How many of these phone users would want a plug-in GPS module? Even at less than 1%, it would be worth to make the effort.
  
• Note that even today after the announcement, iPhone users have been voting that they still would like a GPS module.
  
• Lastly, don't forget the iTouch users. The iTouch doesn't have GPS (at least for the time being), so who will take care of them?
  

So to make the story short, I will keep on doing what I have been: working hard to come out with a GPS module for iPhone and iTouch users at an acceptable price and as soon as possible.

PmgR

Compatible? YES!

Just recently, a GPS plug-in for the Maps.app was released by xWaves. The video above shows how my GPS module also works with that software.

The source code for the software was released as well and can be found here and checked out with regular svn. All credit for this software goes to the people at xWaves.

Below is some more information on how the software works:

• The software currently talks to the GPS module directly through the serial port. The standard baudrate is 19200 which I had to adjust to match my module. It will be best if the software is updated in the future to automatically check what baudrate the GPS module is running at. Another option is to add in functionality to work with a gps daemon.


• The xGPS program is a daemon that runs in the background and is started through a plist file in the Launchdaemons directory. This deamon talks to the Maps.app and the serial port and tells the Maps.app to update its location with the data obtained from the serial port.


• The software currently needs to connect to the internet to update the map as it calls the Google website to update its location. It would be nice if someone figures out how to circumvent this and have the Maps.app update its location directly from its database without having to connect to the internet. In that way you could upload your own maps to your iPhone/iTouch and use those while on the road.
  

Then finally one comment on the video. I stated: "...the GPS module is charged through the USB..." What I actually meant to state is that the iPhone is charged through the USB. If you look closely, you can see the charging sign in the video.

Then lastly, before signing off for tonight, I also wanted to let you know that I am currently working hard on the housing design and getting manufacturing for the boards set up.

Froooozen!

I had a busy week. I have frozen the board design and sent out two PCB designs on Friday.

Both boards have the same functionality, but one of them is pushed to the smallest limit in terms of size (15.2mm x 23.4mm, see the left side of the photo). It will have to be seen if this board can be manufactured and assembled automatically with components. In case not, I have the second PCB design which is a little bigger (17.7mm x 23.4mm, see the right side of the photo) and which should not have any problems for fully automatic manufacturing and assembly.

I will be spending the next couple of weeks on the mechanical design of the package. This package will be based on the larger board. The two PCBs have been laid out in a smart way such that both will fit in the same larger package.

If it turns out that the smaller board can be assembled automatically (or if hand assembly of one or two components is not a problem), then the mechanical package can be shrunk in size by just changing one single dimension of the package! That's why it took a little while to come up with the current frozen board design.

You can also see that I have redesigned the website slightly and re-arranged some things: posts in the center, polls and the blog archive in the left side bar, and my human rights related links in the right side bar.

Upon request, I have also added a donation button on the left top for anyone who wants to donate. In addition, I have added some Adsense ad-links throughout the page. I have noticed that they are quite on the topic of the blog and they will also bring in a little bit of revenue when people click on them.

I am glad I was able to get this final board design out the door before the end of May :)
