… storage save us? The smart storage solution Khairul decided to fix the problem by building his very own smart pantry, designed to keep track of ingredients and make sure nothing ever runs out. The project works by monitoring every item in the pantry, and if something is running low, it automatically orders a replacement using Amazon DRS. This project is a great way to remove human error from the process of keeping our cupboards stocked. The best part is it’s easy to do yourself at home with just a few simple components and tools. Check out the full project and instructions here. Smart wardrobe An overflowing wardrobe is a good thing — it allows you to mix up your outfits and dress well whatever the occasion. However, packed wardrobes can also be tricky to manage, and it’s easy to lose track of clothes or end up filling space with items we no longer wear. Arduino user Tan See Youu decided to fix this problem by building his own smart wardrobe. The challenge People today own more clothes than ever before. However, you probably won’t wear all of them. Over time, certain outfits tend to get forgotten and fall back into the murky depths of the wardrobe, never to see the light of day again. In areas with high humidity and warm climates like Singapore, clothes that are left for a long time in the wardrobe can even become moldy. The smart storage solution Tan See Youu’s smart wardrobe helps you manage your clothes and keep track of where everything is, displaying this information on a smart screen. The wardrobe can also push this data into the cloud and share it with your phone via a mobile application. The app can even provide suggestions on what to wear today based on the events in your calendar and the current weather forecast, and it comes with a dashboard showing which clothes you wear most frequently and which outfits you have neglected. If you haven’t worn a certain item in a while, the app can offer suggestions for
