Meet Jewelbots

Jewelbots are more than just pretty jewelry, they are a powerful communication tool. Kids can make their bracelets light up when a friend is nearby or send messages to a buddy across the room. They can come up with their own functionality and program their Jewelbot to behave in lots of cool ways!

Power of open source

Jewelbots are powered by the Arduino IDE, a powerful, yet easy to learn language intended for anyone making interactive projects.

4 Powerful LEDs

16.7 million variations of rainbow fun!

Replaceable Charm

Jewelbots come in different colors and shapes. You can even 3D print your own!

Stylish Nylon Band

Match your mood, your style, express yourself.

Jewelbots Features


Jewelbots have 4 lights that can be programmed to react to other Jewelbots. No other Jewelbots in the area? Not to worry. You can still program it to light up when it’s time for class, or to remind you to practice your violin!


All Jewelbots have a tiny motor in them that vibrates when it gets a message. Kids can send messages to their friends who are nearby by simply pressing on their Jewelbots, no phone required!

The App

Using the free Jewelbots app for iPhone and Android, kids can set how their Jewelbot behaves and interacts with their friends. Don’t have a phone? Jewelbots can still be used without the app!


Jewelbots have a micro USB port on the side, and it can be directly connected to a computer. Using free Arduino software, kids can program their Jewelbots to do all sorts of cool things. Kids can then upload their code to our site and share and collaborate with other Jewelbot users.

For Safety

We are making a product for kids, and their safety is our number one priority. Jewelbots don’t contain a GPS and we don’t store any personal data of any kind.

The Jewelbots App

Using basic if/then statements, girls begin to learn the fundamentals of computer science while engaging with their friends and expressing themselves. They can create friend-groups and decide how their Jewelbot lights up and vibrates when they are together. Once they get a hang of it, they can use the app to write little mods and take their skills further:

Instagram Mod: light up when you get an new like
Twitter Mod: vibrate when you get a new follower
Facebook Mod: flash when you get a message from your parents

…the mod possibilities are endless.
And of course – Jewelbots basic functions can be used without a phone.

Jewelbots is open source - learn more

Open Source
Their Imagination is the Limit

»Certainly there's a phenomenon around open source. You know free software will be a vibrant area. There will be a lot of neat things that get done there.« – Bill Gates

Jewelbots are also open source, so for the curious tinkerer, they offer the perfect platform to explore what is possible with wearable technology communication. Using the Arduino IDE, girls can literally make the bracelets do whatever they dream up. Light up when they get a call on their phone, why not?
