In this build guide, we'll carefully walk you through all the steps of the assembly to make sure you successfully bring your Spencer to life!

This DIY project should be exciting and fun regardless of your previous knowledge of electronics. We hope you're ready and excited to start working on your own voice assistant. Let's get making!

Check out the anatomy guide before you start to learn more about the components you're about to assemble.

In the anatomy guide, you'll learn all about Spencer's components on the main board in more depth. 

Age group

Like it says on the box, Spencer is designed for anyone who's at least 11 years old. 

Some of the assembly steps should be approached carefully, so make sure to have an adult jump in if you need some help with soldering or tightening the bolts later in the process. It's okay to ask for help.

Don't worry though! We'll go through the assembly step by step and provide some useful tips along the way. We'll give you a heads-up if there's something important to keep in mind while assembling.

Assembly time

It should take you approximately 4 hours to fully assemble your Spencer.

Of course, the assembly time depends on your previous knowledge and experience. If you don't have any experience yet, don't worry! It just might take you a little longer to get into the groove and overcome the challenges in the beginning.


You don't need to have any specific skills before getting your hands dirty with this DIY project.

The main objective here is to have fun and learn something new.

So hold on tight, read all the instructions, and get ready to have fun! This is a great opportunity and your first step in your big engineering career.

What you'll learn with Spencer

Spencer's main goal is to provide an educational STEM experience and motivate you to learn something new in the future.

This can serve as a great introduction to the world of electronics and, hopefully, be the first step in your big engineering career!
