Well here is my first attempt at writing about my experience with the sunspot. My local JUG (Java Users Group) volunteered me to create something with a sunspot kit. I decided to create a sunspot tank with 2 DC motors mounted with a sunspot. I thought this was going to be easy but then I realised a few things: 1) bluesoleil conflicts with sunspot detection on a COM port. What this means is that bluesoleil creates so may COM ports for bluetooth devices that when all you want to do is upload a MIDLET on your device the ant script can take upto 10 minutes to find your sunspot instead of 10 seconds. This one took me a while to work out. 2) If you are using standard DC motors and not a servo motor you will need to create a H-bridge configuration so that you can make the motor go forwards and backwards. This would be okay for a person who is good at electronics but me who doesn't really understand the concepts it was a struggle. Anyway back on to it Below is an image of the H-bridge that I have been trying to get working on a breadboard before I bother soldering it onto a PCB board. At the moment it doesn't work as the diodes I used weren't good enough and started smoking on me. I tested by setting up a basic sunspot application that sets high or low on the D0 and D1 pins on the sunspot. I will post the code soon. Anyway here is the picture:  Below is a picture of the start of the chasis of the tank and also a sunspot mounted on it:  |

Hi there everyone. I recently just bought a jailbroken iphone off of ebay. I was quite happy with it. The phone came within 10 days express from the USA. Once received I open it up charged it up and put my vodafone sim card in. It totally worked. I have very happy with it. It works fine and its brobably by far the best phone I have gotten in a while. One of my grips with the Pocket PC is the stylus use and the touch screen not being very responsive when using your fingers. With my iphone I have no such problems. I think I need to get a data plan now as my pre-pay sim just doesn't cut it now. The full web page browsing on the iphone is just awesome with safari. |

While looking at some forums. I stumbled upon this neat plugin that replaces your Windows Mobile Home screen. It makes it look very iphone like. The best thing is it is very fast. Also its totally free and has an auto update feature. The software is currently in beta but they are working hard to improve it. Being Australian myself I had to promote it as its being developed by a bunch of Aussie lads. Below is a screen image of it and also a you tube video of it in action. 
Also its available for download from here |

Ever wanted to wrap table data in XSLT this template will help you out I found it pretty handy. //put this template in between your <td> and </td>
//remember to change $yourTextString (!)
<xsl:call-template name="text_wrapper">
<xsl:with-param name="Text" select="$yourTextString"/>
</xsl:call-template>
//this will display the first 30 chars of $Text then pass the rest to
wrapper_helper
//if no string is left it will stop
<xsl:template name="text_wrapper">
<xsl:param name="Text"/>
<xsl:choose>
<xsl:when test="string-length($Text)">
<xsl:value-of select="substring($Text,1,30)"/><br/>
<xsl:call-template name="wrapper_helper">
<xsl:with-param name="Text" select="substring($Text,31)"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
no more string!
</xsl:otherwise>
</xsl:choose>
</xsl:template>
//this will also display 30 chars of the string, and pass the rest back to
text_wrapper
<xsl:template name="wrapper_helper">
<xsl:param name="Text"/>
<xsl:value-of select="substring($Text,1,30)"/><br/>
<xsl:call-template name="text_wrapper">
<xsl:with-param name="Text" select="substring($Text,31)"/>
</xsl:call-template>
</xsl:template> |

I just came across a cool windows media player replacement for Windows Mobile. Someone has created a media player that has a similar interface to the one on the iphone. Which is a lot more user friendly then the standard Windows Media player. I have attached a link to it and also a youtube video of it in action. link to download
