remoscope - homage to the lumiere brothers early cinema. a remoscope film has to be 1 min, fixed camera, silent and no effects. my first series over the weekend on my security camera placed in various positions in the backyard capturing the movement of plants in the winsd and the movement of the clouds. recorded onto vhs. Also filmed a 1min remoscope of the Greenpeace ship Rainbow Warrior berthed at Dunedin Wharf during sundays open day.

Project two: an interactive ferrofluid Sachiko Kodama: When I Met This Material Also 'protude flow' video here my design may employ a number of audio speaker magnets with the cones removed to make them silent magnetic field generators. (I now realise that this will never work because the largest magnet in a speaker is the fixed permanent magnet) i need to create a ferrofluid, regulate the magnetic fields and create a suitable cointainment vessel for the fluid. procurement of chemicals... through school trying to get: ferric chloride, oleic acid, ammonia and steel wool. This is subject to a hazard assesment process so fingers crossed. Creating the ferrofluid; I intend to use the procedure for synthesis listed here Research into building electromagnets: The key importance of an electromagnet is the ability to control the strength of the magnetic flux density, the polarity of the field, and the shape of the field. The strength of the magnetic flux density is controlled by the magnitude of the current flowing in the coil, the polarity of the field is determined by the direction of the current flow, and the shape of the field is determined by the shape of the iron core around which the coil is wound. chart of technical specs of making magnets Here the effects of time-varying magnetic fields on ferrofluids making ferrofluids dance with computer controled electromagnets Here experiment with two electromagnets (above and below) Here gordon pask'd ferous ear experiments in self constructing dendritic sensor arrays from a ferous solution here Monday 7/4/08 Chemicals Ordered and coming! Starting to reserch electromagnets and their fields, concidering a quadrapole magnet (see pic) but until I have a functioning ferrofluid it is difficult to plan as I will need to experiment. Also concidering a 'sandwich' model having magnets above and below in a low case with transparent sides Friday 18/4/08 freaking chemicals still have not arrived! argh two weeks till project due argh... thinking of plan B strategem using diorama and crazytalk... grrr... Monday 21/04/08 still no oleic acid. found a supplier of copper wire: EMD motor rewinders. have studied more about electromagnets and have found a suitable stand for the installation for $3 at the tip shop. have still to find a suitable container for the fluid apparently a place called Reetveldts is this place to go for scrap metal bits and peices spo am off there for a look... (mon 21st) tues 22nd: breakthrough, found great proffesional type electromagnets at Reitveldts, they want $20 each, plus the oleic acid should arrive tomorrow. Its expensive though it could cost $100 with shipping. this is turning into an expensive project... it better work! I am planning on having 3 independantly controlled magnets on the bottom of a glass dish with potentiometers to control the voltage. This should give alot of control over the shapes in the fluid. wed 23rd: christ! just found out I can't use potentiometers to control the voltage they won't work! it is sugested I use a variable power supply and they start at $239 ferfuxake... eyeing one up on trade me for $65 tho if its dc that is... brought the power supply and it arrived in less than 24hrs! the oleic acid finally arrived today so looks like I'm away... Mon 28th April. first ferrofluid synthesis failed! it did not seem to be magnetic. I suspect that the 'domestic ammonia' in nz may have detergent added or else the ferric chloride has an additive. i will approach the university and see if I can procure chemicals of greater purity from there. in another blow against freedom of the individual the Uni will no longer supply chemicals to 'the public' despite my being an ID carying Uni staff member and post graduate student they insist on my going through my course supervisor. this means asking the harried Sue Ballard to do yet another thing and means delaying once more my project. the worst thing about this is that these freedom inhibiting measures are wrought by people who think they are making the world a better place. the stifling of personal liberty has been an insidious global force that results in the elimination of diversity in our culture. Where will it end? Do we have to have all objects wrapped in cotton wool to stop anyone hurting themselves on hard surfaces? Almost everything I do now has been made more difficult by such measures. I think it is time to make a stand for basic human freedom. WHAT MAKES PEOPLE MORE HAPPY; SAFETY OR FREEDOM? wed 30th: have obtained some ammonia of a more pure nature and am about to try the synthesis again... thurs 1st may: fuck that ammonia was STRONG! the fumes were very intense but I think the synthesis worked this time! Only trouble is the amount of deformation in the fluid was absolutelt tiny; about a half a milimeter. this means that the $65 power supply and $20 magnet I have are useless, now I will have to go to mains power to get a much stronger magnetic field. I brought a pair of rare earth magnets from Jaycar and they made the fluid react quite nicely but work best at a distance of 3-5cm not right up to the fluid. This basically means that I will be unable to make any of the installations that I had planned. Perhaps if one were able to build super high strength magnetic coils using hand wound electomagnets and high voltage but I am not comfortable with that medium. The rare earth magnets were freaky enough. |

documentation of the ferrofluid synthesis |
|||
| this is the assembled chemicals and tools I will use for the ferrofluid synthesis. from left to right we see: steel wool, coffee filters, ammonia (this didn't work and had to obtain concentrated stuff from a lab), ferric chloride made up from the packet dissolved in spring water, 20ml syringe from D.I.V.O, oleic acid ($85!) reaction vessel (jam jar) | ![]() |
||
| reacting the ferric chloride with steel wool till it turns bright green. I used much more 'wool' for the second synthesis | ![]() |
||
| filter out the steel wool and reaction crud | ![]() |
||
| drawing out a further 20ml of ferric chloride | ![]() |
||
| and adding it to the reaction vessel after adding the ammonia swirling the jar continualy | ![]() |
||
| resulting magnetite precipitation is apparent | ![]() |
||
| made a cup of tea | ![]() |
||
| heated the stuff from the jar in a pot till near boiling then very slowly and carefully added the oleic acid. at this stage the ammonia fumes present a real hazard | ![]() |
||
| this is the variable power supply hooked up to the electromagnet (see below) which is underneath the 'containment vessel' this turned out to be too weak so applied... | ![]() |
||
| two rare earth magnets which attracted the fluid very well | ![]() |
||
| you can see that the spikes appear when the magnet is a few cm from the containment vessel. Also I found that the fluid would not spike automatically even with the magnets at the perfect distance, a process of particle aglomeration had to be manually achieved before the tendrilation could manifest. | ![]() |
||
| filmed the fluid reacting for documentation below | ![]() |
||
| ferrofluid experiment declared a sucess at the experimental stage. but as it reacts differently than I imagined and the fields need to be much stronger its back to the drawing board for an installation application | |||
this is the magnet and stand for the installation (experiment):
