Electronics - I recently bought a decent DSO, the "Pinecil" soldering iron, a whole bunch of components. I had some ideas but then sort of hit a wall and lost interest. So now I have a workbench with tools that I will hopefully get back to some day. I think my starting projects were either too difficult, or not that interesting after I implemented them on a breadboard.

Plasma simulation - I really want to understand how fusion and advanced propulsion systems can be simulated and maybe even contribute in some way. E.g. The fusion propulsion being developed by Helicity Space is very interesting. I wish I knew enough to understand their work and maybe do some simulations myself. I tried doing this "Particle In Cell" course I found online but quickly lost interest after a week or so.

I guess I just have a wide variety of interests that come and go. Some of these just seem to be passing interests. I have sort of learned to live with that.
