From: Novel Defence Engineering on 10 Jun 2010 03:34 Hello, I'm looking for people experienced with electronics design and prototyping to help me build a control box for an invention I am trying to develop to a technology demonstrator stage, at an affordable cost. This is for an invention I recently patented - GB 1000110.5 "Vehicle propulsion and protection system." The control box should be able to independently vary the current-time history through each load - on/off and signal profile (0 - pi sinusoidal, Dirac delta, ramp, etc.). There should be a current limiting feature to cap the current through each load, for a maximum of around 20A. It should be able to remember the activation sequences and the user should be able to adjust the current-time history through each load fairly easily (e.g. as a numerical matrix in a plain text file). Initially I expect 20 independent loads but this number can go up/down and the design should be easily scalable accordingly. For now it will run off the mains. A close example of such a device would be dot matrix light boards with moving words/pictures on them, achieved through periodic activation of the lights independently. If anyone thinks they can do the job, please contact me. Contractors in the UK -> England -> Cambridge area are preferred. Thanks. Novel Defence Engineering www.noveldefence.com

I would imagine fowling up your system with a few bags of iron filings would be easy. I could even imagine being able to use your magnetic field to transport a charge closer to the hull and using your reactive armour against you.

More armour? Thank you very much :) Seriously, the system is meant to work with a collection of magnetised particles behaving as an aggregate fluid. Having iron filings would not affect the operation of it. > I could even imagine being able to use your magnetic field to transport a > charge closer to the hull and using your reactive armour against you. The vehicle is not a single large electromagnet, but rather a collection of small dipoles. The far field magnetic field strength decays to an inverse cubed law at increasing distance from the dipoles, and the strength of the field is proportional to their dipole moment.

Having iron filings would > not affect the operation of it. Seriously if I added iron filings then something would have to go as there is a limit to what you can hold there. If its your ceramic balls you are losing protection and probably propulsion. You will have to put some kind of filter in the system to remove the junk. PS you can't patent that now as its in the public domain, not that it will stop the Americans from trying. ..
