All things Raspberry Pi and Time Lapse

A word of caution about Newark/Element14

I recently purchased a second Raspberry Pi to use while my original one is confined to a small box taking pictures. And while I was at it I purchased a Gertboard. This board allows for interacting with physical items such as motors, buttons, and lights. And by using this separate board it protects the Raspberry pi. It is possible to interface directly with the GPIO pins on the Raspberry Pi, but if the wrong voltage is applied it is possible to fry the Pi. So the Gertboard offers a solution by protecting the Raspberry Pi.

While I was looking for the Gertboard and the Raspberry Pi I found a precision knife and some solder (the Gertboard comes as bare board and soldering is required to build the board) and these items were only a few dollars. So I added them onto the order. When I checked out it only showed me the Merchandise total (because the items were Back Ordered) so I clicked Submit. The next day I get charged over $10 for one of the $3 pieces and they had shipped it separately from the other pieces. And another item that i ordered was a Direct Ship from the UK meaning that it had a $20 shipping charge. I would think that their website would ask before charging over twice, or in the second case four times the amount for shipping as the original product. However this is not the case, and there are multiple bad reviews online saying the same thing. After getting the run around – I contacted chat, who told me to call, who told me to email – I finally got it straightened out and we got the problem resolved. Newark was nice enough to reverse the shipping charges on the small items, and the large items are still in Back Order status.

So this is a word of caution before purchasing from Newark/Element14. I am NOT saying to not order there, I am saying to be cautious about the shipping charges.

My Gertboard is not supposed to ship until October 17th. If anyone has one I would love to hear your thoughts on it!

RaspLapse is installed!

On Saturday (Aug 25) afternoon the RaspLapse project was installed! I am really looking forward to the results. For now it is situated on the Fan/Exhaust end of a greenhouse. I am going to leave it there and take pictures as they pull existing tomato plants out. Then it will be ready to watch the new plants grow! Here is a before and after shot of the installation process. (Sorry about the picture quality…)

Before…

And after…Image

The box on the right is holds the camera, Raspberry Pi, and some connections between the camera and the Raspberry PI. The box on the left holds the power connections, and the Ethernet cable so I can download the pictures without ever touching the enclosure holding the camera.

EXTRA

Here is a picture of what the camera is shooting… This is the raw image.. No editing at all. In the end I will crop/rotate in Photoshop.

Time Lapse shot on Canon S2IS

This is my Vimeo video link that I shot about half of a year ago. I setup my Canon Powershot S2 IS under our orange tree shooting the clouds that were particularly awesome that day. This is the result!

 

The second one is one that I shot using the same camera of some ice cubes melting. This one provides what I think of as a time lapse perfect opportunity. There would be no other way to capture this!

Updated BOM (Bill of Materials)

Here is a link to my previous post for everything that is required for the project. The main things that were added are numbers 10 and 11 which is a case to hold all of the power cables, and some brackets and plastic screws to hold the Raspberry Pi inside the the case. 

 

I hope to install the setup in the next week or two in a greenhouse and watch tomato plants grow for about 3 months. This will provide some great testing time, and then i will setup for a year time lapse after that. 

 

Looking forward to setting it up!
