What tech item do you get great satisfaction from owning/using?

Some quick background on myself. I have recently been struggling on and off with anxiety, and then depression caused by the emotional exhaustion from the anxiety. It's left me looking for distractions and craving excitement and that feeling of satisfaction you get from owning something.

Previously my PC used to cover that, however its 5 years old now and the feeling has faded. I recently bought a steam deck as well, but a major upset in my life kinda ruined the excitement of that (i still use it though).

I've been obsessing over tech, and something that has always brought me a great sense of satisfaction is getting an item to solve a problem or fill a need, or even just an item that I use a lot (Also because I subconsciously won't allow myself to spend money unless I can really justify it).

I've been getting an envious feeling watching one of my relatives use their new 3D printer regularly and just craving that feeling. So tell me what brings you great satisfaction!
