How I made my timelapse of the Derwent River

 If you haven't yet watched the timelapse yet you can view it on YouTube here https://youtu.be/jFxGNTsc6YE. If you want to watch just the raw footage look here https://youtu.be/7xBx3e2mPcQ. The setup I used for the timelapse was a webcam on a tripod connected to a raspberry pi 4.

Some of the numerous problems I encountered were the webcam letting in light due to its shape - I solved this with a 3d printed shield. Another problem was the windows were double glazed - solved with some black paper with a cutout for the camera. Also the raspberry pi doesn't have a chip for timekeeping so whenever the power went out (like in the power outage) I had to set the time again. My code was also a bit problematic, for some reason my USB could only hold about 2,500 photos.

To create the overlay I used a flask webserver that was taking the filename extracting the time and date then showing the information on top of the image served from a file server with all the images. I then used chrome driver to capture all of the frames. I may publish my code on my GitHub. If I do I will update this article.

How to get iView shows as an RSS feed!

I was sick and tired of missing new episodes of my favourite iView shows so I created an app which transforms iView into an RSS feed. To get the RSS feed for a show you can simply take the iView show id https://iview.abc.net.au/show/<showid> and use it in the app https://iview-rss.maxstuff.net/rss/<showid> like so. Easy right? This only works on shows with multiple episodes for obvious reasons. If you want a website that will send you emails for RSS feed content - check out follow.it  Try checking out maxstuff.net/iview-rss  as it will soon have a configurator. For more options and documentation see the readme on GitHub .
