Joule Thief Electronics Kit – From Breadboard Prototype to Real PCB
Learn electronics the way engineers actually do it.
The Joule Thief Electronics Kit is a complete, hands-on learning experience that takes you from first principles on a breadboard all the way to a finished, soldered PCB. This kit is designed to teach not just what a circuit does, but how engineers think when developing real electronic products.
You will build two versions of the same circuit:
A fully working prototype on a breadboard
A professional-style PCB version that you assemble and solder yourself
Along the way, you’ll learn how the Joule Thief circuit works, why each component is used, and how a simple idea becomes a finished electronic product.
What You’ll Learn
- How the Joule Thief circuit works at a fundamental level
- How to prototype and test circuits on a breadboard
- How to transition from a prototype to a PCB design
- Practical electronics skills: component selection, layout, and assembly
- How engineers approach problem-solving and iteration
All builds are supported by full step-by-step video instructions, guiding you through both the theory and the practical build process.
What’s Included in the Kit
Everything required to build both versions of the circuit is included:
- Breadboard
- Custom PCB
- 2 × AA batteries
- Battery holders
- Terminals
- Resistors
- LEDs
- Toroid cores
- Enamelled copper wire
- Transistors
- Switches
This allows you to create:
- One working prototype
- One finished PCB-based circuit
Tools Required (Not Included)
To assemble the PCB version, at a minimum you will need:
- Soldering iron
- Solder
- Pliers
- Wire cutters
- Safety glasses
Important Information
- Soldering is required to complete the PCB build
- Educational use only – this is not a toy
- Recommended age: 14+
- Contains small parts – choking hazard
- Adult supervision required

Why This Kit Exists
This is our first-ever physical kit, created to bridge the gap between theory and real-world electronics. It’s for learners who want more than a pre-built module, who want to understand how things actually work and how engineers turn ideas into hardware.
If you’ve ever wanted to move beyond kits that just “plug together” and start thinking like an engineer, this is where you start.
Quality Guarantee & Returns
- Quality is guaranteed. If there is a print error or visible quality issue, we'll replace or refund it.
