The electronic dice—a beginners soldering project...

A cool introduction to the world of electronics!

The Electronic Dice Kit is a hands-on STEM project that lets you build your very own working electronic dice. Assemble the circuit, press the button, and watch the LEDs flash and settle on a random number between 1 and 6—just like a real dice roll.

Perfect for beginners, this kit teaches electronics, soldering, and circuit design while giving you a fun, functional device you can actually use in board games, classrooms, or STEM clubs. With clear step-by-step instructions and easy through-hole components, it’s an ideal first kit for kids, teens, or adults curious about electronics.

This kit includes a wide variety of components and has plenty of soldering steps, giving you valuable practice for future electronics projects. It's also an ideal kit for educational settings (bulk discounts are available, Contact Us to find out more). Build it. Play with it. Show it off. The perfect mix of fun, learning, and hands-on STEM.

👉 Order today and start your journey into electronics with a project that’s simple, practical, and exciting. Check out the dropdown sections below for more product information.

Learning Outcomes and Benefits

Circuit basics: Learn how electricity flows through resistors, capacitors, LEDs, and transistors to create a working device. Our detailed instruction manual includes the circuit diagram and a complete description of how it all works.

IC fundamentals: Discover how the NE555 timer generates pulses and how the CD4017 decade counter turns them into random dice rolls.

Practical soldering: Gain confidence with through-hole soldering, the most beginner-friendly way to assemble electronic circuits.

Randomness in electronics: Explore how electronic circuits simulate chance, linking physics and math to probability.

Visual outputs: See how seven LEDs can be arranged to mimic dice face patterns for numbers 1 through 6.

Problem-solving: Build troubleshooting skills by checking polarity, fixing cold joints, and debugging non-working circuits.

Confidence and creativity: Finish with a working dice you can use in board games or show off at science fairs.

STEM inspiration: An engaging introduction to electronics, coding logic, and circuit design, sparking curiosity for more advanced projects.

Frequently Asked Questions (FAQ)

Q: What does the electronic dice actually do?
A: Press the button and the LEDs flash before stopping at a number between 1 and 6, just like rolling a real dice.

Q: Does the electronic dice generate a truly random result?
A: Yes. We have performed experiments on these dice to confirm that they deliver a truly random result. You can view the experimental report including all the relevant statistics at the following link: Electronic Dice Randomness Experiment Report.

Q: Why build an electronic dice?
A: It’s a fun, practical way to learn electronics, soldering, and probability. Plus, you end up with a working gadget you can actually use in games.

Q: Who is this kit best for?
A: Beginners (ages 12+) who want their first taste of electronics, students working on STEM projects, or hobbyists looking for a quick build.

Q: Is this just a toy?
A: No—it’s a real, functional circuit that demonstrates how electronics can simulate randomness. It’s both a learning tool and a fun device to use.

Q: Can I use it in place of a dice for games?
A: Yes! It works just like rolling a dice and is perfect for board games, classroom demonstrations, or show-and-tell projects.

Think I've found a new hobby!

I had a soldering iron in the tool box for decades and don't think I ever used it once, so I was intrigued when I seen this little electronics project while shopping for a present on here for someone. It is very cheap so I bought it to give it a go and really enjoyed putting it together and it worked perfectly. Loads of soldering practise in this little kit, well worth it!
