The Raspberry Pi Experience


This year in computer application has been an eye opener. firstly, I’m a grade 10 surrounded by grade 11s which is kind of scary. I didn’t and still don’t know anyone that well so it was kinda hard for me to find a partner for this project but alas I found her.

Working on the raspberry was fun, getting to know how to work with a raspberry pi and learning new things about it.

In project 2, we had to install a software which was challenging but in the end, we got the hang of it.



  • Raspberry Pi
  • SD card
  • Keyboard and mouse
  • power supply
  • Display and connectivity cables (HDMI)
  • SD card reader and writer


Operating system:

NOOBS is an easy operating system installer which contains Raspbian. It also provides a selection of alternative operating systems which are then downloaded from the internet and installed.

Raspberry Pi – Holopainting With Raspberry Pi



Jocelyn - Holopainting with raspberry pi copy

This project’s an unholy mixture of stop-motion, light-painting and hyperlapse from FilmSpektakel, a time-lapse and film production company in Vienna. We’ve covered 2D light-painting here before. This project takes things a step further: meet 3D holopainting.

WLAN On Raspberry Pi

Getting WiFi network details


To scan for WiFi networks, use the command sudo iwlist wlan0 scan. This will list all available WiFi networks, along with other useful information. Look out for:


  1. ESSID:”student”. This is the name of the WiFi network.


  1. IE: IEEE 802.11i/WPA2 Version 1. This is the authentication used; in this case it’s WPA2, the newer and more secure wireless standard which replaces WPA. This guide should work for WPA or WPA2, but may not work for WPA2 enterprise; for WEP hex keys, see the last example . You’ll also need the password for the WiFi network. For most home routers this is located on a sticker on the back of the router. The ESSID (ssid) for the network in this case is student and the password (psk) is studentPassword.


Adding the network details to the Raspberry Pi


Open the wpa-supplicant configuration file in nano:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Go to the bottom of the file and add the following:






In the case of the example network, we would enter:






Now save the file by pressing Ctrl+X then Y, then finally press Enter.


At this point, wpa-supplicant will normally notice a change has occurred within a few seconds, and it will try and connect to the network. If it does not, either manually restart the interface with sudo ifdown wlan0 and sudo ifup wlan0, or reboot your Raspberry Pi with sudo reboot.


You can verify if it has successfully connected using ifconfig wlan0. If the inet addr field has an address beside it, the Pi has connected to the network. If not, check your password and ESSID are correct.

WP-Contact Form


In my opinion we have all been either cyberbullied or the cyberbully whether we noticed it or not. Chatting with your friends through social media about a certain someone on how they look or dress is cyberbullying even though its not to the said person. We as well as the bullies are as much to blame for either being bullied or being the cause of bullying. We post pictures of ourselves and/or other people on social media. We accept friend requests from people we don’t know just because they share a mutual friend with us or because we want more friends. Cyberbullying is a horrible thing and I advise that if you don’t want to be bullied then you shouldn’t accept friend requests from strangers or post things that you have a feeling will be used against you.


Report cyberbullying when you see it. You never know, you might just be the hero
