[Gordon Kirkwood’s] focus as a photographer is in capturing ephemeral phenomena, that is, things that are exhilarating to see but also fleeting. In the pursuit of documenting such blips of beauty found in the natural word, he has taken on engineering the circumstance through which they occur by means of technology.
One of the amazing mechanical creations he’s constructed to aid in his photography is a large computer controlled, bubble blower. A few stepper motors work to dilate three segments of soap-soaked rope engaged at 120 degree angles to create a triangular aperture. When the aperture closes, the segments overlap slightly, covering themselves with a consistent coating of suds. When the segments stretch apart, a fan blows a current of air towards the center, pushing the sheath of fluid into ginormous glimmering orbs which he uses as the focal point in some of his photographs.
More currently, [Gordon] has been developing a body of work that involves zapping botanical subject matter with a quarter-million volts from a portable arc producing device he’s created and capturing the reaction with an ultra low-tech camera (the kind with the bellow and sheet you hide under while exposing the film). Using a method all his own, the shots recorded on large format film are claimed to turn out with even more clarity than any current digital camera in use today. [Gordon] has launched a crowd funding campaign to support a pilgrimage to the majestic island of Hawaii, where he’ll use his lightning producing apparatus on ten different specimens of tropical plant life so that he can record the outcome with his tried and proven technique. (see below an artsy shot of his lightning summoner)
Sometimes Kickstarter isn’t so much about commercialism as it is starting a dialogue with the world and beginning a personal adventure. May the journey lead to new inventions and larger, more ambitious projects! Oh yeah- the bubble blowing machine is a must-see in action. Wicked cool:

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!

Mosquitoes really suck. Joking aside, they spread dangerous and deadly diseases like Malaria, Dengue and West Nile. They like to breed in pools of stagnant water which can be difficult to keep up with. From egg-laying to larval development, still water is vital for breeding mosquitoes. Instructables user [Gallactronics] hypothesized that disrupting the surface tension of potential nurseries was the key to discouraging breeding, and he built a solar-powered device for under $10 that proves his theory.
There are a few standard ways of dealing with standing water. Someone can keep it drained or it can be sprayed with pesticides. By aerating the water, mosquito mothers are far less likely to successfully arrange their eggs on the surface. Even if the eggs take, the turbulent water surface will suffocate the larvae.
This bubbler ticks all the boxes. It starts as soon as it comes in contact with water and sounds a piezo alarm when the pool has dried or when someone removes it. It runs for 10 minutes at 10-minute intervals using a 555 timer and some transistors. The water probes are stainless steel bolts, and it runs on a 6V 450mA solar cell. Be sure to watch the demonstration below.
We love to see this kind of ingenuity and elegance in problem solving. Then again, we also like the idea of killing them with lasers.

Your neighbors are going to love you if you start filling up the back yard with foam at your next party. It’s an easy enough build, but depending on your ability to source the major components it could cost a pretty penny to use it at your next rager.
[Species287] used a big fan and water pump which he already had on hand. All together that saved him about $200 (he’s pricing in Australian Dollars but they’re almost even right now with USD). The soap solution is super cheap, just a bottle of dish washing liquid mixed to the correct proportions with water, but you’ll need a way to apply it to the fan. Some irrigation supplies connected to the fan grate with zip ties did the trick. The pump is submerged in the bubble liquid, causing it to spray from the nozzles near the fan. But this won’t actually create bubbles. The last piece is a bag-shaped hunk of shade cloth from the garden store. Each pore of the cloth acts as a bubble ring. The cloth gets sprayed with soap by the sprinklers and the air from the fan then blows the bubbles.
There’s no video of this project so if you want to see it in action this other diy foam cannon will have to do.
[Niklas Roy] is at it again. He’s applying wind power to his projects by using umbrellas. He was inspired by the shape of an anemometer, and umbrellas turned out to be a great choice because they’re cheap and easy to find.
Anemometers measure wind speed by capturing it with egg-shaped sails (in fact, we’ve seen them built from plastic Easter eggs before). The umbrellas have a much larger area and will capture more wind. Still it’s a big jump from measuring wind speed to generating energy. That’s why he’s not trying to generate electricity, but instead using the mechanical force directly. He took a page from one of last year’s projects and used the dual umbrella setup to power a music box, thereby reinventing the wind chime. The triple-umbrella unit seen above serves as a bubble machine, driving a series of plastic rings through a soapy solution and letting the wind do the rest. We’ve embedded his demo video after the break.

That awful buzzing/beeping beside the bed in the morning might not seem so bad if it were a cascade of bubbles instead. At least that’s what [Will] is hoping for. He took a child’s toy and turned it into a bubble blowing alarm clock.
We’re guessing you’re not going to be too happy with the alarm settings feature. This isn’t using a real-time clock, or any clock at all really. [Will] rolled his own light detection circuit using a PNP transistor whose base is controlled by an LDR. When the light level in the room reaches a certain threshold the bubbles start streaming out of the front of this thing. He test the system in the video by switching a lamp on and off in a dark room.
Up at dawn has never been a way we could describe ourselves, but the one-wire control method seen here could easily be provided by a microcontroller rather than the LDR. Oh, and for those that don’t get it; the [Lawrence Welk] show always started with a screen full of bubbles.

Check out this floating foam letter machine that was shown off at last year’s IFA show in Berlin, the German equivalent of CES. The contraption is called Flogos, and comes from a company named SnowMasters based out of Alabama.
The Flogos machine consists of a helium and compressed air bubble generator positioned below a custom stencil cutout. As the bubbles form, they are forced into a relatively tight formation as they exit the stencil. Once a nice thick layer is established, a small plastic arm is dragged across the surface, liberating the foam from the stencil allowing it to float through the sky as you can see in the video below.
We think it’s pretty cool, and we wouldn’t mind having one around just for kicks. If you were to lay some stencils over a tweaked version of this foam generator we featured last year, you could probably have your own floating foam printer up and running in no time.
Stick around to see the video from IFA that originally caught our attention.
