    Mapping computer state changes as a space.

    I excluded the abstraction process. For very small functions you can map it's space. The process described is effectively path independent. If you know the start and end points and can parameterise it as a function of the localised change you can then ignore the space in between and consider...

    Mapping computer state changes as a space.

    I want to see if we can map the space that is computable programs. You wouldn't consider complex problems, once you mapped the simplest problems into a space of points you can get a distribution. You may see that these clump. Seeing as several of the variables are proportional to the history of...

    Looking for a critique: reactive black body radiation device

    It's a blackbody radiation heat exchanger that controls the radiation exchange through a central focus. It is definitely a cooling system and maybe a heating one. Either way it collects radiation from outerspace and modulates it to the level of radiation expelled by an enclosed volume.

    Looking for a critique: reactive black body radiation device

    I want to get a half convex lens (thick in the middle, flat on one side). And coat it in thermally and optically reactive transition filters. They are to be segmented so to reduce spread of filtering. This will give a view of the sky with any bright light inhibited at the focus. Next to the...

    Sky temperature profiles and black body radiation

    I want to know, excluding the sun with an appropriate boundary, whether it is possible for the balance of bbr to be positive for outerspace rather than on earth? I am thinking of a half convex with an active polariser across-the outer surface which allows through most radiation below the...

    Water/land detection/differentiation from a quadcopter

    Good point. To which I cannot get an exact answer. They do not mention it. Many of the fishfinders pair via bluetooth. Some of them you have to manually set their depth so that it improves the quality of image.

    Water/land detection/differentiation from a quadcopter

    The idea is to suspend a fish finder below it, you can currently get castable fish finders. Then drag it across the beach head and get a rough idea of where the fish are. There will be a issues with drift of the buoy, it would be quite convoluted to get the drone to compensate for this with...

    Water/land detection/differentiation from a quadcopter

    Hello, I want to have a quadcopter drone type set up which can tell how far from land it is. I would go for GPS but I want it to take into consideration the tide, and in general I'm only talking a distance of 50-200m (within shore fishing distance). The ideal system would be a drone that can...

    Advice on building a radio transmitter in the Radio Control band

    I'll have to understand your reply, thank you for asking the questions. Bandwidth. I gather this refers to use of the channel? I can intermittently use the channel, using the RF charging when needed. From what I read it, fair use is important, but not enforced. The actual devices will not be...

    Advice on building a radio transmitter in the Radio Control band

    << Mentor Note -- post separated out of a different thread to deal with a separate question >> Hi, I am looking transmit as well as receive power within close proximity. Currently I am looking at 27.255 MHz AM in the citizens band. It is listed on Wikipedia and in statues I found to be for...

    Simulate a reality by exploiting geometric solutions

    It will essentially be The Matrix. Except every one who plays will be God's and they get to build the world up from atomic structure. The main mechanism of action is people finding stable formations can publish them. You get to name an object and it becomes available as a clip board item to...

    Where would you buy carbon nanotubes?

    Where would you buy carbon nanotubes?

    Wouldn't have to be long ones. Cheap and cheerful amounts. A google search brought up one called cheaptubes.com, any one had experience with them?

    Could one use a capacitor to enhance a capacitive stylus?

    What I want to do is have a mono pole capacitor so that the tip size can be reduced. I'm probably concepting it wrong though to think that would work. Essentially it would be static electricity on a stick.

    Could one use a capacitor to enhance a capacitive stylus?

    What I'd like to know is which direction is the field that is measured? into or out of the plane

    Could one use a capacitor to enhance a capacitive stylus?

    I understand that. What I'm thinking is you could make a finer point without the need for periphery plastic like in these products: http://en.wikipedia.org/wiki/Capacitive_sensing#Styli

    Could one use a capacitor to enhance a capacitive stylus?

    I don't well understand capacitance and its use in touch screens. Just had a crazy idea that you could involve a charged capacitor to enhance the accuracy of a stylus.

    Buckyballs surface chemistry

    I've got a project I'm interested in. Essentially its modifying a melamine foam so its thermal conductivity is at least halved. Was thinking some type of buckyball filler in the matrix might be a ticket. However someone pointed out it maybe a worry about how it would affect the cell...

    Maxwells demon

    perhaps you could make a spherical magnet with all the poles passing through its centre.

    Maxwells demon

    I had the concept of scaling up Maxwells' demon experiment to a marco scale. Replacing molecules of gas with light, rigid, balls. Perhaps coated in magnets with varying poles so they never touch (non-interacting). Would suspend them in a thin fluid with neutral buoyancy.

    What would the products of photolysis degredation of PET plastic be?

    Interested in this because plastic drinking bottles have a taint to them when left out in the sun. I gather its from UV degredation of the PET plastic. I'd like to find a catalyst that would allow the PET byproducts to be non water soluble/sequester or even evaporate.

    Does evolution stop?

    Evolution is generally a reaction to changes in niche availability. These changes may occur do to competition, changes in the supply chain, environmental shifts or over selection. Over selection is possibly the classic, with example of the sabre tooth tiger. Sexual Dimorphism and mate selection...

    Questions about static electricity in automobiles

    I understand it may be far more prudent to just generate the static charge as needed. But thought if theres some already there then it might be enough to be conservative with.

    Questions about static electricity in automobiles

    So, I don't want to disclose why I want to know about this because its to do with a friends invention and it would be unfair to publish too much information without his consent. That's my disclosure so to speak. I'm interested in how static electricity is managed in vehicles. I remember...

    Micro-organisms in the fridge

    Thanks for helping :) So I see that a fridge is too dynamic to have measurable value. Perhaps some particular metabolite could be measurable, but then you have issues associated with scope. Compartmentalised detection could do it, ie built into food containers. But electronics are not suited...

    Micro-organisms in the fridge

    It turns off in my fridge. I can tell because it delay turns on when i open the door just a jar.
