That could work I really like the raspberry pi angle, maybe do articles on various addons you can get for raspi and what sort of IOT stuff you can do. Also add a video walkthrough and cross post on 3speak and dtube, the biggest hurdle for curators is how to know the tutorial wasn't ripped from the web and passed as your own, if you add a video with a voice narrative it personalises it somewhat and let's you get video exposure on those two platforms, just an idea, you don't have to.

Do you have much experience with using raspi for various things?
