I’ve now got a 12000mAH portable power pack. It’s great! Not restricted by power sockets and I can now take the Pi anywhere.

Looks great when customised with a Raspberry Pi sticker.

I connect to my Raspberry Pi via VNC quite a lot, this was the reason I wanted to set up my Raspberry Pi to email my IP address automatically on start up.

I’ve tried before but couldn’t get it to work but today I found a different python script which worked first time. Here is how I set it up.

1. Create a python script and store it in a Directory.

I created a script and called it ‘startup_mailer.py‘ . Click the following link startup_mailer.py to view the code I used. Please note you will need to enter your email account settings where necessary, I use a gmail account.

I stored it in a directory and named it ‘Code

2. Make the startup_mailer.py python script executable.

To do this type the following command in terminal ‘sudo chmod +x startup_mailer.py

3. I now needed to add a line of code to my boot file. I use Raspbian so to access the boot file I typed in the following command ‘sudo nano /etc/rc.local

At the end of the code enter the location of your ‘startup_mailer.py’ file mine was ‘python /home/pi/Code/startup_mailer.py’. Save the changes.

Click the following link rc.local to see what your code should look like once you’ve added that line.

4. Now reboot your Raspberry Pi and you should automatically receive an email containing you Raspberry Pi’s IP address.

Raspberry Jamboree Bag Complete!

Having recently received the kit to go with the Raspberry Jamboree Bag (that I won at Preston’s Raspberry Jam), I thought I would put together a short video to show how it all came together.

 

FileZilla-1

Whilst working on another time-lapse video recently I discovered it isn’t easy to transfer the images from my Raspberry Pi to my computer. For this particular time-lapse there were 786 images. In the past I’ve tried compiling the videos using the Pi but I found this process rather slow. I’ve also tried uploading the images to dropbox on the Pi but with 786 images this was taking a considerable amount of time.

I looked into mounting a USB but could not get it to transfer the files (permission problems) – I think I need to spend a bit more time on that.

Whilst searching the internet for different ways to transfer files from the Pi directly to a computer I discovered FileZilla, it’s a FREE FTP solution. My Pi was connected via WiFi on the same network as my MacBook and I already had SSH enabled on my Pi. I then followed the YouTube video tutorial below and it worked like a dream, all 786 images copied within minutes.
