If you’re ready to graduate from KiwiCo’s other boxes or just can’t get enough (or are just too old for their other subscriptions), you’ll love this box, which is designed to create a hands-on learning experience using everyday items to delve deeply into the science and math principles they embody, along with the design process of the month’s project.
Some of the parts for this month’s project were inside plastic pouches.
We’re excited to make this one!
Everything in this month’s box!
Eureka Crate Maker’s Guide
Like the other crates from KiwiCo, Eureka Crate includes a booklet.
Stereo Headphones
The booklet gives a complete history and details about this month’s project. A lot of people, including us of course, loves music, and this will be very useful! The introduction page welcomed us with fast facts and illustrations.
This booklet means business as it jumps right to the activity.
Eureka Crate Materials
Here are the materials! You may check if you have the complete parts by comparing it to the picture in the booklet.
The instructions kept the continuous flow of the activity easy to understand. The drawings were detailed too. And for the first part, we need to build the headband that will hold the speakers on your ears while you use them.
For this part, we’ll need the following materials: foam pad, fabric sleeve, sticky foam sheets, nuts, connectors, and metal headbands.
After completing the earphone headband part, we can now look into the speaker driver. I suggest you read and explain this to the kids as they will be working with cables and jacks.
Here are the other materials that we’ll also need in completing the headband: hex key, screws, and the wood set.
The booklet is detailed and provides good illustrations that you can easily follow. On this photo, my daughter already connected one of the connectors on the headband, and she just needs to repeat the same on the other side.
The wood set goes into the connectors. This is where the speakers will be attached later.
Here, my daughter is securing some parts with screws.
To lock the screw in place, she used the hex key.
Here’s the other part where the connector will be secured in place when they attach the other wood set.
Now, it’s time to build the speakers. It’s the most important part of this project because it’s where the sound comes from!
For this part, we’ll need these materials to build the interior of the speakers: audio jack, speaker drivers, and speaker housings!
Before you start assembling the speakers, just make sure that you carefully handle the speaker drivers. The plastic membrane on its front is quite sensitive and can be damaged easily, so don’t touch it!
For the exterior part of the speakers, we’ll need the audio cable, ear pads, and some parts of the wood set.
You can also check the booklet to know if what you’re doing is right.
My daughter attached the ear pads to the speaker housings.
It’s a good thing that the guide explains and shows how things are done, making the project an easier task.
The other part of the wood set goes on top of the speaker housing, secured by some screw.
After completing the headband and the speaker part, it’s time to assemble. The guide also gave us a complete detail coupled with good illustrations for that.
The booklet also provided instructions on how you can effectively use the headphones.
The speakers can also play stereo sound. The audio cable even has a volume switch! Awesome!
It’s time to test this puppies out. We just need to plug it in and we’re good to use it!
The stereo headphones can also play different sounds on your left and right ears.
They were able to do it by having the right wiring.
We’re also able to learn more about the headphone designs through the guide, as there’s an article for it.
There are even articles that explain the phenomenon behind the projects that we’re doing.
Here’s the history of one of the most popular and useful inventions intended for music lovers!
Another feature is about the technology that changed headphone history!
For the Design Challenge, they’re encouraging us to make our own amplifier without the use of electricity!
Here’s my daughter testing the headphones!
The design is actually cool! The ear pads also help to make it feel comfortable even if you’re using it for a longer time.
And most of the parts are secured with screws so there’ll be no worries that the headphones will easily fall apart.
The jacks also fit well.
It is a really fun and very useful project for us, especially when the kids just want to focus on what they’re listening too. I can also use this one when I listen to audiobooks without disturbance!
Eureka Crate is the crate for creative individuals who are always up for challenging activities, crafts, and projects! It’s also a great bonding activity for the whole family, as the box and its contents are appropriate for any age! We love this activity as the item we’re making is very useful for us, the kids love music and they can use this one. The design is fantastic too. My daughter didn’t really have a hard time completing it as the guide is really informative and detailed. We even learned about making our own sound amplifier without using electricity! It’s really a good box, and we highly recommend this box as it is fit for all ages!
