This month we’ll be showing you how to make a hovercraft. This project is a super low-cost way to repurpose a couple of drone motors and learn about these cool vehicles. We’ll explain the basics of how these amphibious vehicles work, and then will share step-by-step instructions for building your own cracker box hovercraft. This […]
Cool Engineering Projects
Propeller cars, DIY doorbells, breadboard circuit games and more! Get building in minutes with these cool engineering projects.
Browse the tutorials below for everything you need to have fun with young makers in your classroom, homeschool, or makerspace. We tell you what supplies you need, explain how things work, and also embed some fun and helpful videos.
You might also just wish to take a look at our simplest basic electrical circuit projects or our slightly more advanced electrical engineering projects. We also have a helpful basic electronics page that teaches skills such as how to use a breadboard and multimeter.
We’d love to hear from you! If there are cool engineering projects that you’d like to see here or you can’t find what you’re looking for, please leave us a comment or send us an email at info@geekpackhack.com
LDR Circuit: DIY Flashlight Tag Detector
In this post we’ll show you how to build a circuit with a light-dependent resistor (LDR). This LDR circuit will trigger a buzzer when it’s exposed to light. In other words… A flashlight tag detector! This project and all Geek Pack Hack activities must be undertaken with a suitable adult completing their own risk assessment […]
DIY Telephone: Cardboard 2-way phones
Break out the cardboard and the duct tape– let’s wire up a DIY telephone! This project and all Geek Pack Hack activities must be undertaken with a suitable adult completing their own risk assessment and supervising their children at all times. Years ago we visited a friend who lived in a large apartment building. Because […]
STEM Challenge: Make an overflow alarm
Can you make an overflow alarm with just a few basic supplies? To do this STEM challenge, kids try to build a buzzer that goes off before water overflows from a tub. STEM stands for Science Technology, Engineering, and Math. This is a great activity to do with school-aged kids in the classroom, as a […]
DIY Solar Fountain to Build in an Afternoon!
Here’s a project to build and enjoy in the summer: a DIY solar fountain (in a wheel barrow)! This is a straightforward project to make. And what’s great is that it’s 100% sustainable, since we’re using solar power to run the fountain. This project and all Geek Pack Hack activities must be undertaken with a […]
Arduino Temperature Sensor Code: Automated Fan
For Arduino projects that include temperature sensors, it’s necessary to understand how to write the Arduino temperature sensor code to program your Arduino board. In this post, we’ll show you how to write the Arduino temperature sensor code to build an automated fan. When the temperature gets too hot, the fan will turn on. The […]
How to Create a Robot: Easy RC Puppy
Haven’t you always wanted to know how to create a robot? Read on to learn how to create an easy robot that you can build at home. We call this robot Fido, because he comes when you call him with your working cardboard remote control! This project and all Geek Pack Hack activities must be […]
How to Make a Speaker (and How it Works)
If we told you that we were going to show you how to make a speaker out of a paper cup, you would probably say, “oh yeah– we’re going to make a string phone.” But we’re not going to do *that* project. What if we told you that you would be able to hear the […]
DIY Valentines That Light Up in 7 Easy Steps!
Did you know that you can make DIY Valentines light up with a simple LED circuit? Light up DIY Valentines are fun and easy to make. They’re also a super STEM (and STEAM) activity for kids (and adults!) to learn about electricity.. And, if you want your Valentine to stand out among all the Hallmark […]
How to Make a Radio: Amplify an AM “Crystal” Radio
We’re going retro this month to bring you this tutorial on how to make a radio. This project and all Geek Pack Hack activities must be undertaken with a suitable adult completing their own risk assessment and supervising their children at all times. We live in an age where digital electronics make it possible to […]
