Goals

  • To provide out-of-the-box support for devices and tools commonly used by students participating in LIL’s learning activities.
  • Offer additional services to increase productivity. This includes remote desktop and file sharing.

Raspbian Version

  • The latest release is currently based on 2013-09-25-wheezy-raspbian

Modifications

v 0.9.3 – Oct 28, 2013

  • Fixed a DOS->Unix file format error that prevented the gogotalk.py module (the core library that communicates with the PiTopping board) from working correctly.
  • Two versions of the Raspbian image are released. One using ICS and the other using the default DHCP client configuration.

v 0.9.2 – Oct 8, 2013

  • Networking now set to ICS (Internet Connection Sharing) mode by default.  The IP is set to 192.168.137.100. To switch to a DHCP mode, run the following at the command prompt:

cd /etc/network/
sudo cp interfaces.default interfaces

Then reboot.

  • Created a symbolic link “easygogo.py” which points to “pibot.py”. This allows backward compatibility with older code that still uses the easygogo name space.
  • Fixed an indentation bug in gogotalk.py which prevented it to run properly.
  • Upgraded fingerscan.py to 0.9.2
  • Upgraded rfid_sl500.py to 1.1
  • Upgraded pibot.py to 1.0.2

v 0.9.1

  • Installed “PT Scratch”. A special version of the MIT Scratch programming environment  with added support for the PiTopping add-on robotics board.
  • Installed PiTopping Python API. This allows python programs to access sensor and motor control ports on the PiTopping add-on robotics board.
  • Installed a custom Python API for SL-500 RFID reader/writer.
  • Installed a custom Python API for the FPO-001 V2 fingerprint reader
  • Installed device and python APIs to support serial ports (PySerial), WebCAMs (OpenCV), GPS devices (gpsd), AirCards to send SMS (gammu), plotting on Google Maps (pygmaps), and many other libraries.
  • Installed Python libraries to access the Raspberry Pi’s GPIO pins.
  • Installed Samba to allow file access on the Raspberry Pi over the network (i.e. use \\raspberrypi\pi on windows machines to access pi user’s home folder).
  • Installed xrdp server to allow remote desktop access using RDP clients such as windows’s remote desktop connection.
  • SSH has been enabled.
  • The time zone has been set to Bangkok (GMT+7). To change this, use the rasp-config utility.
  • Installed SPE, a Python IDE, to offer a better Python programming experience.
  • Disabled Raspberry Pi’s use of the built-in serial port for remote terminals. The serial device (/dev/ttyAMA0) can be used freely (by the PiTopping add-on board).
