Connected World Contest

Get creative with wireless connectivity.

We challenge you to design something wireless that connects to something else. Simple.

If it connects to something and it’s wireless, it's eligible. It doesn't need to connect to the internet- get creative: local systems, WiFi, Bluetooth, BLE, and your very own protocol are all in the running.

Nowadays it seems that if something can be connected to the internet, it will be connected to the internet. We’ve seen everything from WiFi enabled refrigerators, to laundry machines and cat laser pointers, but we also know there’s plenty left to be explored.  

We’re asking you to imagine: if you could give anything connection capability, what would it be? Your device could monitor its surroundings with a sensor and could send information to tell you when animals are sneaking into your garden (with or without internet). It could be a device that starts the coffee maker while you’re sleeping or a communication device to talk to space. The possibilities are endless.

If you want to go the Internet of Things route, there are many free IoT dashboards and platforms to help you work with your internet devices and data, such as Adafruit IO, Digi-Key’s IoT Studio, ThingsBoard, and For a non-cloud solution, you could check out this article describing how to setup a Docker environment for use with a Raspberry Pi.

Judging Criteria

Beauty is in the eye of the beholder. That said, here are some criteria judges will have in mind while reviewing entries:

  • Creativity: Is the concept interesting and unique?
  • Execution: Have you built something with attention to detail in solder joints, wire bends, etc.?
  • Functionality: Is the circuit minimally functional? Does it go beyond the basics in an impressive way?
  • Backstory: How well has the story been shared about how this was conceived and built?

I really like this rule: "Projects that were entered in previous Hackaday contests and did not win a prize are eligible for submission as entries in this challenge. These projects are eligible without further additions."

That lets us work on our existing projects without having to constantly restart them.

What about acoustical waves? Does it sound good for the contest? Does a human (or a dog) counts as something else?
