    Biokinetic Animation

    BK2 Render #2 from Ben Jarrett on Vimeo.   In order to visualise the biokinetic interface I was proposed for my Masters, I simulated the look using the Animation function from within Solidworks + Photoworks.  It's a bad way to animate, in that the model still acts as a Solid, therefor[...]

    MIRToolbox Outputs

    I have been using the MIRToolbox plugin for MATLAB in order to analyse music.  By using four standard (non DRM, free) tracks over the course of my experiments, I hope to able to make correlations between music, gesture and form by running Self Organised Mapping (Neural networks) over the results.  H[...]

    Electromagnetic Coil FEA using FEMM

    After winding several coils by hand, I wished to eliminate the guesswork and model the coils using Finite Element Analysis with the freeware program FEMM. After talking to design engineers at Buckley Systems and Wellington Drive, I realised that they are striving for focused flux lines with the a[...]

    Electromagnetic Driver Circuit - LTSpice

    In order to power the grid of electromagnets via the low current 5V PWM outputs on the Arduino Duemilanove, I had to design a basic drive circuit with the advice of the Electronics department.  It's really simple: a Darlington stage increases the current output produced by the PWM pinout, this signa[...]

    Multiple Electromagnets: Grid

    In order to test my hypothesis regarding the use of PWM controlled electromagnets arrayed within a grid structure I have made a prototype.  The Arduino Duemilanove board that I am using has 6 native Pulse Width Modulation outputs, so that is how many I used.  However a better test would have been wi[...]

    Electromagnetic Coil Winding

    In order to test a Arduino controlled grid of electromagnets I first had to wind some coils after using FEMM to analyse the characteristics of the coils.  Winding 1280 turns by hand is the definition of tedium, so one of the technicians at school very kindly lent me his own coil winding machine as s[...]

    The Tango Brain

    Professor Petri Toiviainen of the Center of Musical Excellence at the University of Jyväskylä in Finland helped create this amazing animation. To me, it is really incredible how the brain seems to be reacting to individual notes, rather than passages, or clusters, of notes.... "This animation sho[...]

    Marsyas & MIR Toolbox

    I haven't electronically updated my project's web presence in some time, despite a great deal of research having been completed. Rather than try and update in the correct chronological order I am going to use the scattergun approach in order to actually do it, rather than thinking about it as I have[...]

    Computational Evolution - Richard Dawkins

    Many biologists, notably Richard Dawkins have used computer based simulation to study evolution. By building virtual objects using algorithms derived from nature it is possible to see natural selection over many generations....this idea of a computer based evolution is integral to my project as I be[...]

    William Latham - Artifical Biology

    William Latham was an early convert from the field of fine arts to the possibilities of computer generated artform using algorithms originally derived from biology. From Wikipedia: Latham has authored a book called Evolutionary Art and Computers together with Stephen Todd, published 1992, bas[...]

    Processing Language

    Processing is a programming language developed for graphic artists and designers. I have begun learning the code as it is also the base for Wiring, the code that controls the Arduino microprocessor boards. This is very exciting for someone like myself who is interested in the intersection of generat[...]

    Diana Lange / Processing

    Diana Lange is a graphic artist from Germany, who has recently created animations that use music (via Fast Fourier Transform data - FFT) to control objects that she has created in Processing. This method of using FFT data to manipulate objects interests me a great deal, and certainly has potential a[...]

    Making the Final Plug

    Making the final plug for the ceramic loudspeaker was fraught with difficulties. I had figured out how to use the Roland Modela CNC machine at school, so decided to make a layered model using a type of MDF called Trimatrx (sic) that contains no/reduced Volatile Organic Compounds, and is thus much[...]

    Second Loudspeaker Prototype

    Following the lessons learnt from building the first prototype mold, I built a second mold, again from laminated MDF.  In this trial I was simplifying the exterior in order to ease the mounting of a plate to attach the driver upon.  Secondly, and more importantly I was investigating methods to obtai[...]

    Test Cabinet Casting

    Here are the series of images showing the machining and casting of the initial loudspeaker mold. The aim here was not to create the final shape/design, but rather test for casting properties. I sectioned the virtual Solidworks model to obtain a series of cutting outlines and then the mold former w[...]

    Midrange cavity experiments

    This is a series of relatively quick (by ceramics standards) slipcast models exploring the feasibility of creating a separate cavity within the main cast for use as a midrange unit.  A former is created and suspended in the middle, this former is then fired away when in the kiln.  Marcel Wanders cre[...]

    ceramics control box

    This is a series of fast handmade clay forms that I built on strofoam formers to output some quick ideas that I had regards control box forms....although none of them are successful per se, I was able to gain some insight into what the eventual forms may be.

    slipcast plug - solidworks

    I have modelled up a plug in Solidworks, originally with the intention of getting it CNCed with the Roland Modela we have at school. Unfortunately it has broken down, and with the only technician in New Zealand currently been in Australia for a month, other arrangements are in order. Back to Sha[...]

    slipcasting testing

    Now that I have decided to use porcelain as the cabinet, I am really needing to extend my knowledge about the technology in a hurry.  Slipcasting is a relatively easy process, it is the forming of a separate cavity within the main cavity that is the problem.  I have been experimenting with some diff[...]

    clay casing technique

    I found that a great way of quickly modelling up casings was to use a rigid foam former. Using some trashed styrofoam, a bandsaw and a belt sander one can make a former in minutes. At first I was draping terracotta directly onto the formers, but encountered cracking as you can see in the pictures.[...]

    Rotary Dials

    I have the concept that if using a rotary dial, it should be an analogy of a SLR camera lens - with the same kind of precision and tactile promise.  I mocked up a couple of quick Solidworks animations to see what effects I could get/ Amplifier Dial Render #1 from Ben Jarrett on Vimeo. [...]

    concrete speaker models

    The cardboard models that I have been making are very useful, but they don't convey the sense of mass, of gravitas, that I am seeking.  With some encouragement from my supervising lecturer, Dr Cris de Groot, I made my first slabs of concrete, I mean models.  I didn't have quite enough concrete for t[...]

    The loudspeaker I am building is a little unusual, mainly due to the driver selection.  I am using two drivers; a Jordan JXr6HD for the midrange and treble and a Tangband W6-1139SI for the bass.  I will write about the downwards facing bass driver in another entry, so let’s turn our attention to[...]
