A digital controller for my smoker that would control the temperature and smoke output so that I could start cooking before bed and be done by the time I woke up. Ideally it would keep a log of internal meat temperature and internal smoker temp through time. I know you can buy commercial products that do most/all of this, but I think it'd be a fun side project.

An isomorphic CMS built in react. This one I'll probably get to and leave as a proof of concept. I'm personally fine with over-engineering things for my amusement, but wouldn't want to subject clients to my woes. But, who knows — could end up working better than expected.
