问HN：有什么有趣的小众爱好吗？
我在寻找一些新颖有趣的项目，希望能够在其中有所贡献，而不是那些已经非常拥挤的领域。
在2022年，我开始接触OpenAI的强化学习环境（RL Gym），正好是在第一款非指令型GPT-3模型发布的时候。我曾考虑更深入地进入机器学习领域，但最终犹豫了。在此之前，我对3D打印机、机械键盘、无人机等也很感兴趣。这些领域都经历了爆炸式的发展，虽然它们依然很有趣，我也非常喜欢我的Browns键盘，并为本地黑客空间管理Prusa打印机，但就我个人而言，这些领域已经，换句话说，工业化了。
现在我有时间和资金来投入这些项目，不再像15岁时那样，只是在评价我知道永远不会购买的Ender主板升级。
目前我正在制作一个国际象棋引擎，但这个问题已经被解决了。还有生物黑客（biohacking），尽管设计可以植入我身体的芯片非常有趣，但我只有一个，不想过于冒险。一个有前景的想法是“个人计算机2.0”，人们尝试在HCI（人机交互）方面进行创新，虽然我对此很感兴趣并且有一些研究想法，但我希望在深入研究之前再多探索一下。

I'm looking for something novel and interesting, that isn't absolutely crowded that I could meaningfully contribute to.<p>In 2022 I was toying around with OpenAI's RL Gym, right when the first non-instruct GPT3 model came out. I was thinking about getting into ML a lot more, but hesitated.
Before that it was 3D printers, mechanical keyboards, drones, etc.
All of these have exploded, and while they are still very interesting, I do love my Browns and manage Prusas for my local hackerspace, they have just, for the lack of a better term, industrialized.
I'm also now in a position where I have time and money for it, not like when I was 15 and rating Ender motherboard upgrades I knew I'd never buy.<p>Right now I'm making a chess engine, but that's already a solved problem.
There's also biohacking, and while designing chips to go into my body is really interesting, I only have one, and don't want to push it too far.
One promising idea is a kind of 'Personal Computer 2', where people try to innovate HCI, and while I really like that and do have some research ideas, I'd like to explore a bit more before delving deep into it.
