Imagine if you could play with technology like Elon Musk 

We’ve created a series of fun electronic kits that will help children and adults understand the basics of new technologies everybody’s talking about. 

Also, they’re easy to build, code, use, and play with!   

Every three months, you’ll get a box of custom-made electronic components along with an instruction booklet, code examples, and video tutorials online.

Each quarter’s box is unique and based around a specific topic and serves as a new learning chapter that will take you from Padawan to Jedi master.

If we were to put this short, CircuitMess STEM Box is a combination of education, electronics, and toys.

Everything we produce is unique, designed with love and tested by kids and adults

Every project you’ll get was playfully designed for the CircuitMess STEM box.

We do not simply resell other products for a discounted price, we spend 1000+ hours of research, development, and testing for every project you’ll get.

We’ve gone so far that we’ve even coded our own operating system CircuitOS (no developers were harmed while making this)

Less than 1% of Earth’s population knows how to make new technology

Everybody knows how important technology is, but just a small fraction of the population knows how it works and can invent new technology.  

We’re here to change that. Our goal: turning consumers into creators!

Thanks to our kits, you will join the fancy 1% club.  

Every Box consists of the following parts:

1) Unique DIY electronics

2) A quick-start instruction booklet (for offline usage)

3) Video guides and additional coding and learning tutorials on our learning platform 

Every project was carefully developed especially for the STEM Box  

Every box is oriented about a specific topic and will help you learn about the important technologies of tomorrow.   

Devices from some STEM Boxes can be interconnected and paired or used together to further your learning experience (and be more fun).

STEM Box #1: Spencer – Build & code your own voice assistant 

Spencer is a DIY voice assistant that talks, lights-up, connects to the internet, and understands simple voice commands.

He also has a funny personality, tells jokes, and finds new ones online.  

Spencer has a microphone and understands what you say (like, REALLY understands).

You can code new functions that will be triggered when you say certain sentences or words.  

The LED display on his belly has a colorful RGB grid consisting of 128 pixels that can show data, custom icons, animations, and scrolling text.

Some out-of-the-box things Spencer can do as soon as you assemble him:

• Read the news 
• Tell you the weather forecast for your area
• Memorize the things you say
• Set an Alarm or reminder
• Tell you the upcoming calendar meetings

What you’ll learn:

What you can do with it:

• Make spencer fetch news from the internet and read them in his funny robot voice
• Code spencer to display a funny 8-bit picture of a banana on his LED display every time someone Tweets something funny
• Teach spencer to recognize basic voice commands
• Make Spencer happy or sad (we’ve implemented a tiny bit anxiety in his base firmware, that’s why you need to talk to him)

STEM Box #3: Wheelson –  Build & code your own AI self-driving car 

Autonomous cars are the future and we’ll show you how it works.

This tiny wheeled robot has a camera and a microcomputer and can be programmed to read autonomously navigate a small road while driving just like an autonomous car would (yeah, like Tesla).

It has built-in Bluetooth and Wi-Fi so you can connect it to the internet or your smartphone.

Wheelson also has an LCD display where you can see what the robot sees.

When applying different filters and computer vision algorithms, you’ll see a different output on the screen so that you can understand how robots see and interpret the world around them. 

It is powered by two small electromotors and has a rechargeable li-po battery included. 

What you’ll learn: 

What you can do with it:

• Drive your newly assembled robot buddy around

Box #5: Chatter – Build & code your own encrypted wireless communicator 

Chatter is a free, private, security-first texting device.

It comes in a pair because texting yourself is not as fun as you think.

Initially, we wanted to make a walkie-talkie. Then we figured out that nobody speaks on the phone these days and messengers with emojis and GIFs rule the world… and memes of course.  

Unlike your regular phone, this device does not need a cellular network or a SIM card to work because it creates its own wireless network and communicates with other Chatter devices you’ve paired it with.

It uses the so-called “LoRa” low-power wide-area network technology in order to send text messages, emojis, memes, and GIFs. 

Chatter uses a publicly-available set of frequencies that are allocated for use cases like this one.

The messages you send to other Chatter devices are encrypted and are not passing through an internet service provider so you can share as many secrets as you want with your friends (maybe we should’ve programmed a pinky swear button). 

This device is not a replacement for your regular phone and has the range of an average walkie talkie – around 1 – 7km depending on the surrounding area (concrete buildings and basements are usually not a good spot for getting a good range with this thing) but it can prove useful in certain situations.

The main purpose of Chatter is education and showing people that you can communicate free and remotely without big corporations and the internet.

 What you’ll learn: 

What you can do with it:

• Text your friends for free
• Load custom emojis and memes on the device (you don’t want to be a normy, this thing needs to be updated regularly)
• Code a jumping dinosaur game for your Chatter 
• Play the preloaded snake game on it

STEM Box #6: Clockstar – Build & code your own smartwatch

With this kit, we want to show you how to make and code your own smart wearable device. 

Clockstar is equipped with a dual-core ESP32 microcomputer and has Bluetooth low energy and Wi-Fi onboard.

It connects to your phone using our mobile app and can mirror your smartphone’s notifications to its 128×128 TFT color display. 

Clockstar is also equipped with a gyroscope, accelerometer, and a magnetometer that can be used for precise motion tracking.

The watch uses machine learning to recognize and memorize different movements that you can assign to trigger certain actions.

For example, you can train your Clockstar to play/pause your phone’s music app whenever you perform the floss dance.

What you’ll learn: 

What you can do with it:

• Check the time (yes, it actually shows time!)
• Connect it to your smartphone and mirror notifications 
• Control the media app on your phone with your smartwatch
• Use machine learning to detect when you do a certain Fortnite dance and automatically send a laughing-crying emoji to one of your friends

For kids, adults, and everyone in between 

CircuitMess STEM Box is for the curious minds of kids (ages 11 and up)  and adults interested in electronics, coding, and technology.

We’ve done some research and here are the most common buyers of our educational kits.

1) A caring parent that wants to teach their kids something new

When the kids ask him if they can play Fortnite now, he asks “what’s Fortnite?  

2) An adult who knows nothing about electronics and probably works as an accountant, but would really like to learn something new about the interesting world of technology. 

3) A child prodigy that is doing science and electronics experiments in his/her parent’s garage all the time.

4) A full-stack developer that spent 10 years behind a MacBook

He basically knows everything about computers, but he never saw what’s inside a device IRL.  

STEM education is still not there, but STEM Box is here to change that 

STEM (Science, Technology, Engineering, Mathematics) education is crucial for everybody’s future. Still, STEM education is not there yet.

Most educational STEM products are not engaging enough for kids. They lack imagination, fun, and usability in children’s daily lives.

That’s why we designed a line of products that are going to teach you the skills of the future all while actually being fun to use. 

All the cool kids are learning by doing!

Learning about machines by reading a book is boring. STEM Box is going to teach you by doing something with your hands.

CircuitMess Resources – our dedicated learning platform

This is a place for all our users to find tutorials, share their creations, exchange knowledge, and download apps and games other users have made.

Learn how to code with CircuitBlocks – our unique coding platform 

CircuitBlocks is our graphical programming interface that helps newbies get into physical programming.

We really hate installations! That’s why CircuitBlocks automatically makes sure all the necessary components and drivers are installed.

In CircuitBlocks, you code using puzzle-like blocks that represent logical steps your device can take.

When the colorful puzzle blocks are placed, Arduino C code is automatically generated on the right side of the screen so that you can instantly see how your code would look in C!

We’ve learned how to code and design electronic devices thanks to the internet and open-source technology.

Thus, we want to push our work back into the community. 

All our products’ software is fully open-source and available for you to download on our Github page.

The hardware schematics are also open-source and available online.
