[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:

Forget flashlights, and leave those burning lasers at home, [Ben Krasnow] built a search light using a 1000W xenon arc lamp. That box you see on the side of the trash-can housing countains a starting circuit that shoots 30 kilovolts through the xenon lamp to get it started but it is separate from the power supply. [Ben] started experimenting with the lamp back in April but recently finished the project by using the inverter from an arc welder to get the 50 amps at 20 volts needed when the lamp is on.
The insert on the left of the image above is an outdoor picture of the beam. You can make out a tree at the bottom. Take a look at the video after the break for a full walk-through of the circuitry and some test footage of the finished product.

The polyplasmic archophone is a fresh approach to high voltage “arc music“. They are using an Arduino clone to convert signals for the ignition coils. It is still unfinished, but the effect is decent. In the end it will have 2 tiers of voice coils for a total of 13. They are using different materials for the antenna so they can get different colors of sparks. You can see a video of it after the break and we must say the effect is quite nice. Change the lighting on that video and we could imagine this being the set to a [Joules Verne] movie.

When [Justin Quinnell] sent in his beer can pinhole camera, we were just floored. The parts are easy to obtain, and the process for building and ‘shooting’ with the camera are near effortless.
The really impressive part of this hack is letting your camera sit for 6 months facing the sun. Yes, you read that correct, a 6 month exposure. Check out after the break for one of his astonishing shots, and trust us, its well worth the click. Continue reading “Beer can pinhole camera”
A leyden jar is basically just a simple home made capacitor. We’ve shown you how to make them before. This, however, is how you make a ridiculously large one. [Nickademuss] used a five gallon bucket to make his leyden jar. That’s five whole gallons of lightning. The video, which you can see after the break, shows it light up the entire room when it lets out a fairly formidable spark. This is dangerous folks, be careful.

When welding with an AC arc welder, it is often necessary to “scratch start” them to get the arc going. For those unfamiliar, it is just like it sounds. You drag the head across something just like a giant match. There are some that come with an arc stabilizer or “high frequency starter”. This is preferred, but they can be hard to find. [Bill] shows us how to make one of our own. Though you may have an easy enough time finding a big transformer, you might run into some difficulty finding the capacitors, and tungsten spark gaps. If you manage to get your hands on them, you can follow [Bill]’s schematic and build one of these starters for yourself.
