Fukui Dinosaur museum 福井県恐竜博物館

Fukui Dinosaur museum is one of the three biggest dinosaur museums in the world along with Royal Tyrrell museum and Zigong museum. In the early 1900s, people did not believe that dinosaur existed in Japan until 1986. A high school girl found a tooth in Fukui which had been identified as a dinosaur tooth later. After the discovery, more research had begun  and more discoveries had been found. Seven new species has been discovered, including Fukuiraptor, Fukuisaurus, Fukuititan, and Fukuivenator. The museum was built in 2000. Its shape looks like an egg. However, it was designed as it required a huge space to display dinosaurs fossils. To make the space look better, they did not want to have any pillars near the dinosaurs. The main hall is divided in two sections, one is most for carnivore, and the other is for herbivore.

In the main hall, there are three floors. The basement is main entry, a simple hall way displaying fossils.

On the first floor, the T-rex is brought to life! This vivid t-rex is showing its fury. It is said that dinosaur lays eggs from the excretory organ. IMG_7757.JPG

The bones are used to estimate the dinosaur’s age. It touches like tree. IMG_7758.JPG

Hadrosauridae has crest on its skull. It was used for making sound.

Tyrannosaurus Rex!! Its skull is the most complicated part of all exhibited dinosaurs.

How do we know it is a dinosaur?  Dinosaur was evolved from Archosauria. A dinosaur’s skull has a large opening in the front of eye socket. Dinosaur can stand with their legs straight. Their tooth has its own socket. People misunderstand dinosaur. Pterosaur, Ichthyosaur, MosasauridaePelycosauria are not dinosaur! Is all dinosaur cold-blooded? No! Some are ware-blooded.

A view from second floor. It is just amazing to see so many huge dinosaur walking around! It reminded me “Night at museum”. The T-Rex was chasing Ben Stiller.

Taking photos of these 30m dinosaur is so difficult!

One of my favorite! Albertaceratops is so cute, isn’t?

This dinosaur museum is located 4 hours by train from Osaka. I recommend to stay a night before visiting the museum. In the next morning, go to take the earlier train from Fukui station to Katsuyama station. It takes almost an hour. Once arriving the station, you will need to take a bus from station! It is a long way trip. However, the dinosaur won’t let you down!! It totally worths it! By the way, you can buy a ticket combo from Fukui station, which includes the tickets of train, museum, and bus, around 2000 Yen.

Intel Galileo 2 with USB WiFi Dongle (RT3070)

The WiFi dongle I am using here is Edimax EW-7711UMn

Here I will talk about how to use it on Intel Galileo 2

prerequisite

Install Linux on Intel Galileo 2

Establish communication through terminal

Step 1.

This USB Wifi dongle is supported by Intel Galileo 2, so we don’t need to install driver.

Just plugin it on the board.

$ iwconfig

Find the dongle identifier as “wlp0s20f3u1”

螢幕快照 2015-10-11 21.00.31

The example here is based on WPA WiFi Router

killall wpa_supplicant
ifconfig wlp0s20f3u1 up
wpa_passphrase "YOUR ESSID" "YOUR PASSWORD" > /tmp/wpa.conf 
wpa_supplicant -BDwext -i YOURWIFIIDENTIFIER -c/tmp/wpa.conf

Then you will see “Successfully initialized wpa_supplicant”

If it appears “ifconfig: SIOCSIFFLAGS: Operation not possible due to RF-kill”, when you are entering “ifconfig wlp0s20f3u1 up”.

rfkill unblock all

You can scan to search nearby SSID

iwlist YOURWIFIIDENTIFIER scan

Make a file “udhcpc.sh” in /etc as below code

#!/bin/sh
# udhcpc script edited by Tim Riker <Tim@Rikers.org>
[ -z "$1" ] && echo "Error: should be called from udhcpc" && exit 1

RESOLV_CONF="/etc/resolv.conf"
[ -n "$broadcast" ] && BROADCAST="broadcast $broadcast"
[ -n "$subnet" ] && NETMASK="netmask $subnet"

case "$1" in
  deconfig)
    /sbin/ifconfig $interface 0.0.0.0
    ;;

  renew|bound)
    /sbin/ifconfig $interface $ip $BROADCAST $NETMASK

    if [ -n "$router" ] ; then
      echo "deleting routers"
      while route del default gw 0.0.0.0 dev $interface ; do
        :
      done

      for i in $router ; do
        route add default gw $i dev $interface
      done
    fi

   echo -n > $RESOLV_CONF
    [ -n "$domain" ] && echo search $domain >> $RESOLV_CONF
    for i in $dns ; do
     echo adding dns $i
      echo nameserver $i >> $RESOLV_CONF
    done
    ;;
esac
exit 0

Then run

udhcpc -i YOURWIFIIDENTIFIER -p /var/run/udhcpc.pid -S -s /etc/udhcpc.sh

You will see like this

It works now!!

Intel Galileo 2 Linux installation

This tutorial is about how to running Linux on Intel Galileo 2 without FTDI to USB Converter.

In the end, we will be able to develop APP on Intel XDK

Instead of FTDI converter, we use wired connection to a DHCP enabled router.

Requirements:

  • Intel Galileo 2
  • micro USB to USB converter
  • micro SD card (above 2 GB)
  • RJ45 ethernet cable

Step 1.

prepare micro SD card

download the latest image file from http://iotdk.intel.com/images/iot-devkit-latest-mmcblkp0.direct.bz2 and extract it

format your memory card as MS-DOT (FAT) format

using shell command to unmount the card

diskutil unmountDisk disk3s

replace “disk3s” from your own disk Identifier which you can find in Disk Utility.app

using shell command to install the image file

sudo dd bs=8m if=iot-devkit-version-mmcblkp0.direct of=/dev/disk3s

replace “disk3s” as before

This may take serval minutes.

Step 2.

insert the micro SD on Galileo 2

connect the ethernet cable and the usb cable to your DHCP router and your computer respectively.

power it up.

Open Arduino APP on your computer
using the below code to detect your network status


 void setup() {
 Serial.begin(9600);
 //It’ll not continue until you send an ‘a’ through the serial monitor
 while(Serial.read()!='a'){
 Serial.println("hello");
 delay(1000);
 }
 //Display ifconfig result to serial monitor
 system("ifconfig > /dev/ttyGS0");
 }
 void loop() {
 }
 

Upload it, and open Serial Monitor in Arduino APP.

send a string “a”

螢幕快照 2015-10-11 13.38.28

You can find your IP Address as 192.168.0.118

Step 3.

use the below shell script in Terminal

 ssh root@192.168.0.118 

It will ask you “Are you sure you want to continue connecting (yes/no)? yes”
Then you can use this script to check your IoT develop kit version

  cat /etc/version 

Step 4.

Install Intel XDK on your computer

create a template using OnBoardLED

螢幕快照 2015-10-11 13.49.31

At the drop down list – select a device.

add manual connection

Address as the IP address you got

and the user name is root

Press the button Install/Build (The second button near the drop down list)

and press the button run (The fourth button from left)

You will be able to see the LED on board blinking

Luxembourg Adventure – Luxembourg

Luxembourg is not only a country but a capital of its country surrounded by Belgium, France, and Germany. After Brussels and Strasburg, Luxembourg city is the third capital of European Union. The highest GDP in the world 114,512$ the second biggest commercial center after US. Geography: One of the smallest sovereign nation in Europe. A population is 55 thousands. How to go to Luxembourg? I took the TER from Strasbourg, which took about 2 hours. What was the first impression in Luxembourg? TGV-route-map It wasn’t as small as I thought. Its terrain wasn’t flat! There were many valley within the city. It was first a castle, which was easy to defense thanks to advantage of lots of cliffs. As I walked around the city, I could see numerous of bridges. Under these bridges usually is where old town located. My hotel is Luxembourg Youth Hostel, which located in one of the valleys. It wasn’t very far from the main train station, however, trolling a suitcase in such rock roads, and ascended, descended was really painful. IMG_1509


Luxembourg Youth Hostel Website: Click As a hostel, it is really comfortable to stay. I was staying with 3 friends. We had a room with a toilet and a shower. Be aware to take your own towels and lockers, if not, you have to pay some money to rent it. This hostel has no kitchen. They server breakfast, lunch and dinner, which in my opinion it is the cheapest food you can find in Luxembourg, each meal around 9.9 euro. Each person per night is around 25 euro. On the way to train station, there are a lot of shops, supermarkets, which you can buy food there as well.


Where to visit? This city is based on its castle, which was first built at AD 963. It is a UNESCO world heritage. There are two circular walk you can take.

  • Wenzel Circular Walk
    • A tour through time and space, connecting the Upper and Lower towns: “Bock” promontory, Old Town, Wenceslas ring wall, Alzette valley with its unique fortifications. The Council of Europe has rated this walking tour as an “outstanding” cultural itinerary.
  • Vauban Circular Walk
    • The Vauban Circular Walk, named after the famous French fortress builder, Sébastien le Prestre de Vauban (1633-1707), leads visitors through parts of the fortifications from the 17th, 18th and 19th centuries.

Monument of Remembrance

The centrepiece of the monument is a 21-metre-tall granite obelisk. Atop of the obelisk stands a gilded bronze statue of a lady, representing Nike, goddess of victory, or “Queen of Freedom” (Friddenskinnigin in Luxembourgish), holding out a laurel wreath as if placing it upon the head of the nation. At the foot of the obelisk are two (ungilded) bronze figures, representing those Luxembourgish soldiers that volunteered to serve for France; one lies at the base of the statue, having died in service of his country, whilst the other sits, mourning his dead compatriot. (From Wikipedia)

Interesting to see all the bridge was under maintenance. Lots of constructional materials were lying under it.

IMG_1576

Friends were swinging! When we were about to leave, two police officers came. One asked us what we were up to here, while the other was sniffing around like we were taking drugs and he wanted to find an evidence. They frightened us. We were just enjoying swinging when no kid was playing there.

Musée Draï Eechelen

It is all about history.

Philharmonie Luxembourg

check some programs here. Maybe you might be interested to enjoy a feast of music.


Summary After staying in Luxembourg for three days, I almost explored all the outdoor tourist attractions by only walking. This city in my opinion, it doesn’t have really clean streets, however, the streets are mostly wide. Some places are still in construction around Europe Union Zone. The most interested thing to me was its spectacular geographic position. Seeing huge bridges anywhere, lots of plantation under bridges, like a big park! Walking under bridges is like I escaped from the busy city. Bridges are a great combination of middle-age buildings, modern buildings, and the mother nature.
