Monasca is "Monitoring at Scale" for OpenStack and cloud services. It is a little tricky to run in its current form. There are a number of services that make up Monasca, and a number of underlying services (kafka, zookeeper, spark, etc) that are needed.
Add on top of that Ceilosca (Ceilometer metering using Monasca as a back end) and the list gets longer.

About 3 years ago I wrote some Python and Kivy code for my Samsung Galaxy S4 in QPython. Unfortunately, QPython updated and broke its kivy compatibility. I've been waiting for them to fix it, but mostly have given up.
So instead, just investigate how to turn the kivy code into an .apk for installation on an Android device! There are directions for this on the kivy website.
A few years ago I wrote the "worst 3D Printer". Basically, it takes a 3D model (VRML) and slices it to bitmaps, which can be arranged on paper and printed, then manually cut out and glued together. As you can imagine, just doing a small print could take 500 layers, so it could take a day to assemble (hence "worst"). 
To be more useful, I want to rewrite the old code to properly support STL format. I attempted this once, but had trouble with the normals and getting the lines to connect correctly. So a rewrite would be good.
I recently got a Fitbit Versa 2 smartwatch (thank you wellness incentive) and found there was a clock face that looked like a Linux prompt. Which got me thinking about creating my own. The dev.fitbit.com site looks helpful and worth following their quick tutorial. Mix in a SUSE logo and a tail that curls/uncurls with the seconds and it may become a great way to show off some nerdiness.
