Nerdy and uninspired? I can highly recommend taking a look into the infinite hobby that is #AmateurRadio (also known as #HamRadio).

Ham radio lets you explore radio physics, antenna design, propagation, mesh networking, satellites and space contacts, portable and off-grid operation, DIY electronics and SDR, while also teaching you how to listen, be patient and to work within limits. It's a global social network without platforms, algorithms, adverts or optimisation. https://open.substack.com/pub/g5doc/p/finding-locals-in-a-long-distance
