Mounting Samba

instruksi mounting samba ke raspberry pi

sudo apt-get install smbclient

sudo mount -t cifs -o user=IRZA,password=S***,sec=ntlmv2,rw,file_mode=0777,dir_mode=0777 //192.168.30.97/Public /home/pi/data/

untuk raspberry pi bisa dimounting di Windows.

sudo apt-get install samba samba-common-bin

edit file /etc/samba/samba.conf

tambahkan:

  workgroup = yes
  wins support = yes

dan berikut ini:

[pihome]
   comment= Pi Home
   path=/home/pi
   browseable=Yes

Updated Robot WishList

This the original link.

1. I would like to have a mobile workstation for my laptop, i usually change place while working.. living room, backyard.. etc (still in my home)
2. Making the robot available to Indonesian language is better.
3. I don't watch TV so much  but I would like to have recent news from selected RSS internet feed
4. Communicating with people.. i mean telephony system in my robot.. i can perform calls from my laptop and vice versa.
5. I want to check email.. and someone read it for me.
6. Browsing the internet by voice or virtual touch (without mouse?)
7. Entertaing robot..
8. I have music clips or movie clips that i like to see many times. (building database and a navigation menu for search)
9. I shared my laptop with my wife, and some other people.. so i cannot close the laptop for only one software. maybe other people can use the system too..
10. Video capture
11. I love music and love playing drums.. i want to have a recording station while jamming with my friends.
12. Chatting with the robot would be nice
13. Should be relatively cheap.. =)
14. I like to have a menu system for my robot
15. The robot should have a brain for navigating my house.
16. The robot can recognize face and objects..
17. Home controlled by robot.. this is good
18. Robot Emotions? Leaf have that
19. The robot can take or bring me something... (i think it's very hard)
20. This one is really deep..   i want to ride my robot. transportation in my neigborhood maybe?? (last priority :) )

21. Sync with Social Media / Facebook / Twitter / email

22. Design is Modular. Can add Head / Arm / other Interface.

23. Remainder - Sync with Contacts and Google Calendar.

24. Update with weather and Traffic Jam CCTV.

25. Can use APM - Mission planner and Turnigy Remote

26. Interface to ROS

Flash Arduino UNO / MEGA menjadi device MIDI

Salah satu implementasi arduino yang menarik adalah membuat arduino menjadi midi device.
Langkah berikut untuk flashing arduino

Saya menggunakan arduino mega 2560 dari DFROBOT bisa dibeli disini

1. download dfu-programmer / unzip di harddisk anda download disini
2. download hex yang sudah dicompile   download disini

3. Connect Arduino ke computer via USB
4. reset Arduino dengan menghubungkan 2 solderan ini (pin)

5. Nanti Arduino mereset dan setelah connect kembali dia menjadi ARDUINO DFU
6. PENTING: Install driver windows dfu dengan mengarahkan ke directori dfu yang telah didownload
7. Jalankan langkah ini:

dfu-programmer at90usb82 erase
dfu-programmer at90usb82 flash Arduino-usbmidi-0.2-mega2560.hex
dfu-programmer at90usb82 reset

8. Lepas USB dan Connect kembali.

Anda tidak bisa mengupload sketch apabila sudah memasang ini. Upload implementasi anda sebelumnya.
atau mereflash kembali ke MEGA-dfu_and_usbserial_combined.hex yang ada di directory
arduino-1.0.5\hardware\arduino\firmwares\atmegaxxu2

Semoga Berhasil.
