A Homemade Bubble Robot For The Kids

bubbles-machine

Kids generally can be amused pretty easily, but when jangling keys stop holding their interest you might want to take a look at [drenehtsral]’s new project. He’s created an automatic bubble robot (YouTube link) that keeps the kids endlessly entertained!

The project started as an idea at a festival where one of [drenehtsral]’s kids took great interest at a bubble machine. [drenehtsral] had never heard of a bubble machine before, but it turns out that it’s pretty simple in practice. All that’s required is a tank of soapy water, a motor to turn the bubble wands, and a fan to form the bubbles and make them waft gently through the air.

[drenehtsral] also used a 12V battery for power, some other hardware to hold it all together, and a 5V regulator and some other control electronics for the fan and the motor. He notes that he could have bought a bubble machine but in true hacker style found it fun to build himself. The next step in this project could be something to vary the size of the bubbles, or perhaps a set of wheels for the robot so it can entertain the kids on the move!

The Lightgame Project: A Multiplayer Arduino Game

lightgame_3Summer is upon us. The Lightgame Project is a multiplayer reaction time based game built around the Arduino. It’s a perfect rainy day project for those restless kids (and adults!). Designed by two undergraduate students [Efstathios] and [Thodoris] for a semester long project, all the hard work has already been done for you.

There are tons of reasons we love games that you can build yourself. For one, it’s an amazing way to get children interested in hobby electronics, making, and hacking. Especially when they can play the game with (and show off to) their friends. Another reason is that it is a perfect way to share your project with friends and family, showcasing what you have been learning. The game is based on your reaction time and whether or not you press your button when another players color is shown. The project is built around two Arduinos connected via I2C. The master handles the mechanics of the game, while the slave handles the TFT LCD and playing music through a buzzer.

I2C is a great communication protocol to be familiar with and this is a great project to give it a try. [Efstathios] and [Thodoris] did a great job writing up their post, plus they included all the code and schematics needed to build your own. It would be great to see more university professors foster open source hardware and software with their students. A special thanks goes out to [Dr. Dasygenis] for submitting his student’s work to us!

Introducing Mirobot, A DIY WiFi Robot For Children

We’re quite sure that fathers parents people reading Hackaday wonder how to introduce their children acquaintances to the wonderful world of electronics. The Mirobot (Kickstarter link) might just be a good way to do so. As you may see in the picture above the Mirobot is a small WiFirobotics kit that children can build themselves to learn about technology, engineering and programming.

The laser cut chassis is assembled by snapping it together. All the electronics are left exposed to the outside so children may try to figure out which component does what. The robot is configured over your home WiFi via a Scratch-like visual programming tool. Everything (PCB, Arduino code, user interface) is open source.

The platform is based around the Arduino compatible ATMega328, two stepper motors, a Wifi module that can behave as a client or access point and 5 AA batteries. The campaign stretch goals include a collision detection sensor, line following functionality and finally a sound add-on.

Adafruit Launches Educational Show Aimed At Kids

adafruit-kids-show

Adafruit Industries just posted the first episode in a new educational series aimed at teaching kids about electronics. The episode is entitled “A is for Ampere” and teaches the basic theory behind electrical current. The subject seems like a common one for A-to-Z themed electrical tutorials. [Jeri Ellsworth] did a similar episode but hers is aimed more at the electronics hobby crowd.

[Limor] and gang (that’s [Collin Cunningham] dressed up as [Andre-Marie Ampere]) seem to be all-in on this project. The episode features ADABOT, the blue puppet which takes on the role of the student in this episode. After demonstrating a mains circuit breaker tripping the episode goes on to discuss electron flow and how current is measured.

We’re all about this type of educational opportunity. The age group at which this series is targeted have never known a day without touchscreens, they should know at least something about how those devices actually work.

Only You Can Kick A Child’s Balls Into Space

We had a lot of fun with that title. Of course when you’re talking about launching a thousand ping pong balls into space there’s no end to the puns which can be made. But this is actually a fantastic initiative to get people of all ages excited about science and near-space experiments. [John Powell] offers school children the opportunity to send an experiment into space. He’s Kickstarting the next launch, which is scheduled to take place in September. This way each entrant can fly their project for free, then get the results and a certificate back once the weather-balloon-based hardware is recovered.

There is one size restriction for the program. Each experiment must fit inside of a ping pong ball. But you’ll be surprised what can be accomplished. [John] reports that the most simple, yet interesting project is to place a small marshmallow inside the ball. As it rises through the atmosphere it will grow to fill the entire ball, then be freeze-dried by the the extreme temperatures. Some are not so low-tech. There’s an image of a tiny PCB holding a DS1337 and some sensors. It’s an atmospheric data logger that will provide plenty of information to analyze upon its return.

Fuzzy Time Used To Keep The Kids In Bed

Like many parents, [Mike Tsao] is plagued by his kids’ urge to rise like the dead long before he’s ready to wake up. In an effort to preserve sanity, he built this clock to let the young ones know when it’s okay to get out of bed. Fittingly, he calls it the OK-Wake.

You may notice that the clock doesn’t have a display. That’s because his children are still too young to tell time (this is the foundation for needing a custom clock). Instead, that LED acts as the feedback. At night it will be off. Starting ninety minutes before it’s time to wake the LED will begin to pulse red, increasing in frequency as the target time approaches. When it’s okay to get out of bed the LED turns green and exhibits a pleasant “breathing” behaviour.

An ATtiny25 drives the device, along with an RTC chip. The single button is used to set the alarm. Actual time doesn’t really matter at all. Instead, the button just sets the alarm for twelve hours from when it’s pressed.

Choreographed Christmas Light Show (x4)

[youtube=http://www.youtube.com/watch?v=GeAwYmQOf3g]

[Lucas] is at it again this year. Not satisfied by the computerized systems available on the market, [Lucas] decided to build on last year’s project. To save a bit of cash, he built the setup around Parallax’s low-cost SX28 proto board. The system is capable of controlling 102 channels, with 8-bit dimming. 6 boards control 7 channels each and are communicated to through a serial protocol (reducing the whole setup to only 36 feet of wiring).

More importantly, he’s teamed up with 3 other neighbors who also share a passion for outdoor Christmas lighting and they’ve put together the Christmas Tour of Lights. Money raised from all donations goes directly to the St. Jude Children’s Reasearch Hospital in Memphis, Tennessee.
