Flip rig: An extremely light-weight and simple rig for a FLIP MinoHD video camera

A project at work required video footage of a series of veterinary surgical procedures to be recorded for inclusion in an online resource. The project did not have resources (DSLR and personnel) to record the series of surgical procedures nor does the relatively small operating theatre permit an additional non-surgical staff member to occupy the theatre.

With these constraints in mind, I designed and assembled a camera rig from a number of different pieces of hardware to support a Flip MinoHD digital video camera (found in the back of an old storage cupboard) that could be used to record each procedure. The simple  nature of the Flip video camera means that any member of surgical team can start the recording prior to the commencement of the surgery without having to consider the possible complication of operating a semi-professional video camera or DSLR. The light-weight and unobtrusive nature of the Flip also allows the camera to be fitted to the arm of the surgical light. A perfect place to capture a bird’s-eye view of the surgical procedure.

Kollum

Kollum is a concept for a collaborative location-based realtime audio experience that takes place in urban or suburban environments. Kollum is an attempt to conceptualise and capture the elements of location-based audio experiences that incorporate elevation or altitude through cumulative and persistant columns of sound. Users can use the audio recording features of their smart phone or mobile device to create a new audio block that makes up a column at their location  or add an audio block  to an existing column nearby.

This animation is an attempt to visually represent the assembly of a number of sound columns in a urban space (Does not represent actual experience…YET!).

Concept: Slope of the land under classified vegetation determines the severity of a bushfire

Concept for an interactive device that demonstrates how slope of the land under classified vegetation determines the severity of a bushfire.

The learner can increase or decrease the angle of the upslope and downslope. As a result the severity of the approaching bushfire will change. The bushfire’s severity is based on a premise of the fire’s intensity doubling for each 10° rise in slope.

Concept: The distance of vegetation from a building determines the level of bushfire risk to the building

Concept for an interactive device that demonstrates how the distance of vegetation from a building determines the level of bushfire risk to the building. The learner can select a vegetation type, increase or decrease the distance of vegetation from the building and increase or decrease the angle of the slope. The Bushfire Attack Level (BAL) rating, description and level of bushfire risk for permutations of the vegetation, distance and slope variables are displayed based on learner interaction. The BAL rating, description and level of bushfire risk to building is based on data from the Australian Standard AS 3959–Construction of buildings in bushfire-prone areas.

Concept: The activity flow

During the initial design stage of an activity I like to use pen and paper to quickly map out the flow of the activity. The tactile nature of paper allows for scribbles and scrawls, coloured pens or pencils, hasty redraws, cutting, tearing, taping and a rendezvous with the scanner or photocopier. I think something like an iPad or Samsung Tab style device could also give me similar functionality to pen and paper. I’d like one of those. These drawings describe the flow of an activity for an e-learning resource.

 

Concept: Augmented advertising could reduce litter on the streets

Duct tape residue is all that remains of footpath advertising campaign at this pedestrian crossing in Busan, South Korea.

Advertising taped to the footpath at pedestrian crossings is a common sight in areas of Busan such as Seomyeon that are frequented by youth, young people and university students. As a location for advertising it is ideal. It is one of the rare times busy pedestrians will stop, if only for a short time. That’s long enough to catch their eye with some brightly coloured paper. Placement on the footpath is also more likely to increase the potential for a pedestrian to view the advertisement as they gaze down at their smartphone. Accidental line of sight!

The outcome from this type of advertising is the large volume of waste paper. When not being replaced by a brighter more colourful campaign the advertisements quickly tear under the volume of pedestrian traffic.

Augmented advertising could reduce litter on the streets. It’s highly likely the intended audience for the advertising is using their smartphone while they’re walking. So why try to compete with their attention? Why not promote your materials within the platform? This method could reduce paper waste as well as increase opportunities for enhanced experiences such as directions to points of interest as well as sales/purchases.

Flyers and other small-form paper advertisement/promotional material is passed out to passing pedestrians. Eventually it ends up on the footpath.

The Shaker box

This was the first Shaker Box that I built. I repurposed a slightly worn contact mic I had prepared earlier. My reuse of the old contact mic may explain a few things about the shaker box’s performance. These photos first appeared on my Greetings from…Flickr stream.

Concept drawing for the shaker box.
Starting off, I needed a box of some description to house the contact mic and rattly bits. I didn't have a small metal enclosure or tin handy so I used a plastic jiffy box that I had. Happy with the plastic substitute I drilled a hole in it with a 9mm drill bit to ensure a snug fit for the audio jack.
Next step was to prep the piezo that was already assembled as a contact mic. Gently warm the heat shrink tube with a lighter to ensure that the soldered connections are protected.
Now solder the wires connected to the piezo to the audio jack. One to the tip and the other to the sleeve.
I just temporarily duct taped the piezo onto the lid of the jiffy box. The tape won't protect the piezo that much once we start shaking...
Here is a detail shot.
Mounted the jack and tossed in some hair clips and bits of plastic, some people would want to use metal for a potential more "harsh noise" sound. Regardless of the material the piezo will still pick up the "rattle".
The lid is on, the jack has been mounted and it's all duct taped up!
Plug in your lead and hold tight to your little box and...
Shake your thing!
