[GordonKirkwood] needs soap bubbles. Big soap bubbles. Why does he need soap bubbles? Because – soap bubbles!
Actually, [Gordon] is a photographer, and he wants to capture candid moments and fleeting expressions. What better way to inspire wonder and amazement than to be able to produce a giant soap bubble on demand? And what better way to do it than with an intricate, computer controlled giant bubble machine?
[Gordon’s] inspiration for the bubble producing mechanism comes from the end effector of the Canadarm robotic Space Shuttle arm, which used a cable-grapple design to snare and secure payloads. [Gordon] uses a similar principle to interweave bubble juice-soaked strings and pull them apart in a plane to form a soap film. A puff of wind or a quick shot from a fan inflates and launches the bubble, which the mechanism can pinch off for precise control of size.
The amount of work [Gordon] put into the machine is impressive. His Instructables post is incredibly detailed and goes into not only his build but also his design process and prototyping, the science of soap bubble instruments, and even a nod to the work of other pioneering bubble enthusiasts. And he thoughtfully includes a recipe for professional-grade bubble juice, with a secret ingredient that may surprise you.
You say your bubble-producing needs run more toward quantity than quality? Try using the juice in this homemade bubble robot.

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!

While we’re not much for fashion hacks, we’re reasonably impressed with [Karolina]’s faux Chanel bag made of chips. Apparently a grid of black squares is one of Chanel’s trademark looks, and a thousand or so QFP chips makes for a reasonable substitution.
News of the death of our retro edition has been greatly exaggerated. [Brandon] got an old Apple IIe up on the Internet and loaded up our retro edition, so we’re sort of obliged to mention him. He’s using a Super Serial Card connected to an OS X box running lynx. With getty running, he can shoot the output of lynx over to the Apple. Awesome.
Take an old Yamaha organ, convert the keyboard to MIDI, throw in a few Arduinos, thousands of LEDs, and a handful of bubble machines. What you end up with is the bubble organ, as seen at the Bass Coast Festival last weekend. If you want a hands on, you can also check it out at the Rifflandia festival in BC, Canada this September.
Some guy over on reddit created the smallest Arduino in the world. We’re looking at a rank amateur here, though. I’ve been working on this little guy for the last 18 months and have even created an open source cloud based github design for the production model. It’s less than half the size of a Digispark, and also Internet of Things 3D interactive education buzzword buzzword.
[Moogle] found an old Super 8 camera at an estate sale. No big deal right? Well, this one is clear, and it uses light-sensitive film. Your guess is as good as ours on this one, but if you know what’s up, drop a note in the comments.
One day [John] decided he would put a PC inside an old G3 iMac. After a year, it’s finally done. He took out the CRT and replaced it with a 15″ Dell monitor. The G3 was discarded for an AMD, and the internal speakers and slot-load CD drive still work. It’s a really, really cool piece of work.
