Raspberry Pi Accessories

When I first received the PiRack, I thought to myself… what could I do with this device?

 

It then came to my attention that there was a number of things I could do.

 

I could connect four Raspberry Pis together and use the PiRack as a power distribution system using the on-board power jack attached to the PiRack and an external power supply. Image below of possible project.

I could use the PiRack to connect my Gertboard Rev 1 to the Raspberry Pi along with the Pi Cobbler from Adafruit that has a LCD screen attached to it.   Unfortunately   the PiRack is not very good at stacking ribbon cables because the little set of 4 pins on each side holds the cable up and off the pins (this could be a possible design improvement).  I decided that connecting the cables to the back of the PiRack was better and easier.

In addition to having these two devices connected to the PiRack, I thought I could add in more devices, as explained in the below diagram.

The above diagram would a part of my robot project that I have been working on for the past year. As you can see from the diagram, The PiRack would make it very easy to expand the project in an orderly fashion. I have not constructed this with the PiRack yet but as you can see from the above diagram, it is viable to have the PiRack involved in the project in this configuration.

When I saw this competition back in May, I thought: "June 14, that's heaps of time!".  Now time is nearly up.

 

I got to work on my entry this afternoon after reading through some of the other entries.  I knew that I was always going to take a picture of my over-crowded desk (or my den).  So here it is:  dirrectly from the Camera Module...

is the raw result after stitching:

After further thought and consideration, I wrote myself a little python script (which I have shown below) that allowed me to pivot the Raspberry Pi camera on a tri-pod and take images closer up for more detail.  I used Windows Live Phot Gallery to stitch all the .JPGs together, which took a while.  Here is the raw result after stitching the 88 images (@295 MiB):

 

 

And then I cropped the image down to eliminate the black:

And that is it.

Oh, and I couldn't upload the images to Element 14 site... so they are linked to my server.  I hope that is ok.  Happy RasPi Cam'ing!!
