So like I said in my previous post I’m attempting to make a dead simple Flickr uploader. Video explaining this setup here:

Here’s a picture of how it’s all wired up, this will likely not change throughout the duration of the project:

And here’s the python code, it’s very rudimentary:

Thanks for reading!
Cool project! As you said this is the first part of the project so a lot of things are not set in stone. My first few questions
1. how were you thinking of solving the SD card reading part? An external usb one? Or do you have the OS on a USB stick and you can then use the existing SD reader on board?
2. do you feel it would be simpler/better or not to solve this project by using an arduino with a sd card shield instead?
Thank You, this is fascinating. I’ll keep on watching.
Hey! Thanks for the comment
I am right now working with an external usb SD card reader on the Pi, and I’m using an aptitude package called “usbmount” to interface with it.
This kind of thing is probably possible with an arduino, but the way I’m doing it now is much less expensive because I would need an Arduino, an SD card shield and an Ethernet shield. It would also be very difficult to interface with the Flickr API on an arduino, whereas the Pi can use the wrapper that already exists for python.
Thanks for reading, they’ll be a new post within 24 hours with a bit of progress.
