How To Build The Circuits In This Book

An introduction to circuit diagrams and the components you’re going to use.

Build Your First Breadboard Circuit

A step-by-step guide on how to build a circuit.

The Touch-Enabled Light

Learn how to turn something on with the touch of your finger. This super simple circuit will help you understand how to use a transistor and how to control something with touch.

The Steady-hand Game

Use a super simple concept in electronics to build a game. Show it off and impress your friends that have no clue about what you do.

The Cookie Jar Alarm

In this chapter you’ll build an alarm that guards your cookies, so that you can stop worrying about co-workers or family trying to snatch them.

The Dark-Enabled Light

Turn on a light automatically when it gets dark. This circuit let’s you build your own emergency-light or night light. Or you can modify it to automatically turn on your outdoor lights in the garden at night.

The Blinking LED

A super simple way of blinking a light and easily control the blinking speed. Crank up the blinking speed and swap the LED with a mini-speaker to build yourself a sound-generating circuit which you can use to build your own instrument!

The Two Flashing LEDs

Flash two lights with this circuit. The perfect circuit for practicing building circuit with many components. The circuit has a simple function, but requires 10 components, which makes it the perfect practice circuit before moving on to building larger circuits.

The Party Lights

Learn how to use the 555 timer to build some really cool party lights. You’ll learn how to add or remove lights according to your preference. Perfect for building your own Christmas decorations or to make a party come alive.

The Homemade Musical Instrument

In this project you’ll build a homemade musical instrument. Use it as it is for a fun toy organ you can give to a young family member – or customize it to become a fully functional electronic instrument (synthesizer).

The Running LED Show

Create a spectacular light show with this circuit that makes an LED appear to run along a line. Add the LEDs to your bike, your car, your skateboard, or use as a party decoration to make your friends go “Wow!”

    Frequently Asked Questions

    I’m a complete beginner, is this for me?

    Yes, absolutely. The book starts you off with a section on how to build circuits, with a step-by-step example to get you started. It also includes a component guide to help you identify components.

    Is this available as a physical book?

    No, this is only available as an eBook in PDF-format. But, every circuit in the book has a printable circuit diagrams and parts list that you can easily print and bring to your workshop if you prefer that.

    From where do you ship the kit?

    The kit is shipped from a warehouse in the United States. Expect only a few days shipping time in the United States. Expect a bit more if you live outside of the US.

    I know the basics and have some experience, is this for me?

    Yes. One of the most important skills in electronics is to build circuits. Many people know lots of theory without having any practical experience, and they struggle. In this book, you’ll get a bunch of practical challenges that will be useful and fun even if you don’t consider yourself a beginner.

    How long will it take to get access to the eBook?
