I attended for the first time this year after wanting to go since the first year. As someone who watches science techy engineering YouTubers, but hardly does anything with hardware, I had a great time. Even though I'm a fan of some of William Osman's work, I didn't really enjoy the panels. Relative to effort of attendance, they were kind of boring, something you could probably just watch as a YouTube recording.

What I did enjoy alot were the exhibits. There's the spectacle of seeing all kinds of weird and interesting builds in person. But what's really, really enjoyable is that because the exhibits are done by average people who generally don't have a big public following; you can just ask them endless questions and they're more than happy to answer and give such a great insight into the build process, the work that is involved, the inspiration and the little details of all the things that they made. Granted, I will agree, many of the exhibitors are not socially dexterous, but because they're there, they're very willing to talk and explain things. Definitely worthwhile. I even got to use a soldering iron for the first time in a decade years.
