I found Pleo at this site:
UK Shopudland.dk – This site links to the UK Amazon. Price ca 2100 kr with standard shipping included. (I was so lucky that they shipped Pleo with UPS and with a UPS Express saver service level, which means next day delivery also in Denmark)
Since Pleo is in the UK I needed a main power supply converter form the standard used in UK to a standard European connector.
I found one at this site:Ekektronik lavpris
Pleo is a robot hidden inside a cute little dinosaur. The robot comes from Amazon Scotland since it are not sold in Denmark yet. It was shipped by UPS and delivered in Denmark the day after it had left the shop.
Here are some pictures of the dinosaur before birth. I shall mention that you dont doubt that the robot is new is smells like new paint.
Since the robot is from Scotland it comes with a English power connector and it doesn’t fit into a standard Danish power socket so a converter is of cause needed. Its maybe also one of the causes that it isn’t sold in Denmark and Germany yet.
And some of the dinosaur after power on. After the initial birth Pleo becomes active and will of cause play like a dog with a stick.
The fun part is of cause that it is possible to update the software running the robot. With new updates from UGOBE but also with your own custom software. UGOBE plans to release a PDK later this year, but there are already some third party applications available now to ease the development.

The WRT150N has a serial port located on the front of the circuit next to the security button. When the router is open and seen from top front the pins are located as follows (left to right)
The connecter mounted to the main board are shown below. The other wires on the board should be ignored they are from a previous SD mod.
Serial port pins added to WRT150N v1 circuit.
To use the serial port with an ordinary PC the voltage has to be raised to 5 Vcc which the RS232 operate on. This can be done by using a MAXIM 3232CPE IC which has support of converting two serial ports from 3.3 Vcc to 5 Vcc.
Description from www.elfa.se/dk/
3,0 till 5,5 V RS232-sändare/mottagare Fabr Maxim Transceiver för +3,3 och +5 V-system. Behöver endast 4 st 0,1 μF kondensatorer. Pinkompatibel med MAX 232
MAX3232CPE
Here a small print has been fitted with the required components, the MAXIM 3232 IC and the corresponding compensators. The IC is powered by the Gound and 3.3Vcc from the connector described above.
The serial port DB9 and connector from the main board is attached as shown:
The rest of the PIN connection can be seen in the data sheet for the MAX3232CPE.
You can now use the serial port with your PC. If you don't have a serial port on your laptop etc you can use a serial port to USB cable.
The serial port is used by the kernel to send debug information under startup and continues send log messages. The port setting is 115200 8N1.

This blog post guides you through adding a SD card interface to a Linksys WRT150N router. This guide is guild upon the SD/MMC Mod guide found on the dd-wrt web site.
Adding a SD card to your router enables more space to store logs/files or install additional programs and since a standard edition of the dd-wrt fills up most of the space available on the router it leaves only a little space for you to play around with. Since you with the SD card are able to increase the storage available to 1-2GB or more you can host a little FTP or WEB server.
As an alternative to doing this mod of the router is sharing a folder on your computer so it can be used by the router. This can be done through the Samba shares which is supported by dd-wrt this is the standard used by windows. (Samba works only over a wired line) The Samba Filesystem
If we take a look at the SD card we want to add to the router we can see that only a small amount of the SD pins is needed to control it.
| SD Pin | SD function(SPI Mode) | Direction |
| 1 | Chip Select (CS) | IN |
| 2 | Data In (DI) | IN |
| 3 | Ground | – |
| 4 | Vcc (3.3v) | – |
| 5 | Clock (CLK) | IN |
| 6 | Ground | – |
| 7 | Data Out (DO) | OUT |
| 8 | Reserved | – |
| 9 | Reserved | – |
The SD card
From this we can se that we need the following pins
The SD card operate at 3,3 volt there fore wee first need to find a ground and Vcc connection point on the circuit board. When the SD card are powered up it needs some way of communicating with the rest of the router; we need to find at least 2 output pins and one input pin.
We need to find a grounded point this is very easy since it is present all over the PCB. Normally all metal housings are fore example connected to ground.
Since the power supply on the router is 12 DC we can not use it directly we need another power source from the circuit board where we can measure 3,3 volt DC.
Output means some way we can control the SD card. Here the LEDs are the most obvious choice. You can find out which LEDs are software controlled by loggin into the router by telnet or SSH and using the gpio command to test the IO ping from 0 to 9 looking for a LED shifting from on to off-on-off and so on.
Here are a little script to make the pin switch between 0 and 1:
To find an input pin use:
Then you will se a 00 or 01 when it goes on and off.
Now the important part. I made the IO tests as described above and found the following:
| GPIO PIN | Usage on WRT150N v1 |
| GPIO 0 | – |
| GPIO 1 | OUT: Power LED |
| GPIO 2 | – |
| GPIO 3 | OUT: Security LED Orange |
| GPIO 4 | IN: Security Switch |
| GPIO 5 | OUT: Security LED Green |
| GPIO 6 | IO: Reset – don’t set this pin high your router will reset it self. |
| GPIO 7 | – |
| GPIO 8 | – |
| GPIO 9 | – |
Here are how I decided to wire the SD card:
| SD Pin | SD function(SPI Mode) | Router IO | Router PIN description | Wire color |
| 1 | Chip Select (CS) | Ground | Black | |
| 2 | Data In (DI) | GPIO 5 | Security LED Green | Yellow |
| 3 | Ground | Ground | Black | |
| 4 | Vcc (3.3v) | Vcc 3,3 v | Red | |
| 5 | Clock (CLK) | GPIO 3 | Security LED Orange | Green |
| 6 | Ground | Ground | Black | |
| 7 | Data Out (DO) | GPIO 4 | Security Switch | White |
| 8 | – | – | – | – |
| 9 | – | – | – | – |
Wiring points
Remember to solder to on the negative side of the LED the other side is not lowered enough to change to logical zero.
I tool the power and ground from JP2 (listed from right to left):
Now you have to solder the SD card to your print. I took a socket from an old USB 7 in 1 card reader.
Here are some pictures of the soldering of my router

Now we have to get this new par (the SD card socket) fit nicely inside the plastic box.
Now login to the dd-wrt web GUI and set the GPIO pins
If you want to use the SD card for storing JFFS/IPKG then you have to mount it.
The SD card will be formatted as EXT2 on startup so be patient it has to format it at first start. But you can see the interaction with the card on the LEDs.
You can use WinSCP to access the cart from your computer. Remember to use SCP.
Installing packages on the router:
Preparing /jffs for /opt
Installing ipkg-opt and uclibc-opt

Here I will list some use full tools for setting up your wireless network properly. There are a lot of tools for Linux and Windows xp for discovering wireless networks and their settings and signal strength but they usually does not support Windows Vista.
Here are the tools I discovered:
Vistumbler is a tool for Vista like the NetStumbler. It is an AutoIt script that uses the netsh to get wireless information.
Vistumbler provides information like, SSID, Encryption, signal strength etc. Below are some screen shouts shown
The program supports also GPS location tracking, this means that you can collect the GPS coordinates belonging to the AP’s you discover and export them to NetstumblerToKML as shown below

![image_preview[2]](http://blog.lausdahl.com/wp-content/uploads/files_imported/WindowsLiveWriter/Wirelessnetworkdiscoveryandvisualization_116AC/image_preview%5B2%5D_2.jpg)
Vistumbler is free and can be downloaded here
More info about Vistumbler can be found here
Inssider is a simple free tool that allows you to visually see all wireless traffic. It graphs the signal strength along a timeline of each WLAN in a visual, simple-to-understand format.
Each network will be listed with the information discovered about it.

Her er nogle billeder af kælderen på hotellet.
Først ses saunaen og tørrerummene.
Herefter har vi opgangen og vaske rummet. Og informationen fyldt med oprydnings poser som dem vi fik til at pakke vores ting i da vi forlod hotellet.
In Windows Vista have the well known HyperTerminal been removed which is a bit annoying when working with ex. Serial communication. But I found this free program, it looks like the usual hyperterminal.
I have been working on refactoring a protocol for communicating with a blood glucose measurement device since the manufacture haven’t released any. To make it possible to reconstruct a protocol I observed the program delivered with the device with this Free Serial Port Monitor. It enables you to se what is been send and received on a Serial Port at different levels of details.
