really old thread, but chua circuits are what you are looking for. www.chuacircuits.com the circuit diagram there looks to be what you are describing, but probably by now you have encountered it in your research.

Maybe this is too obvious, but I was surprised to not see it anywhere in the list. I've always considered this THE interactive physics/science website and have used it since high school: http://hyperphysics.phy-astr.gsu.edu/hbase/hph.html" The explanations are clear, simple and exhaustive...

http://www.chuacircuits.com/sim.php" this is a simulator for chua's circuit in 3D, with interactive features so you can manipulate the values. The page has a lot of info actually, including the equations used and the rest of the site has some great videos and pictures. This simulation is...

here is a simple HTML5 program (javascript) used for solving Chua's circuit equations: http://www.chuacircuits.com/sim.php" you have to view the source code and the attached file www.chuacircuits.com/canvas3DGraph.js But the page itself is great an introductory look at the strange...

Yes exactly. Both are issues really, even though I would only need 1/13th the volume compared to if I used water.

Too bad about copper sulfate...thanks for the info though (love the hair). golden syrup/Treacle=slow as molasses+specific gravity of 1.4ish? tomato sauce and paint will just gum everything up I don't know any fuels or fuel oils with densities much greater than water. Maybe I just am not...

Barium sulFIDE is soluble but..."BaS is quite poisonous, as are related sulfides, such as CaS, which evolve toxic hydrogen sulfide upon contact with water. "

It's insoluble in water and alcohol...

No kidding! I've seen alibaba come up in a lot of searches but it never looked that legitamate. I'll have to look into this. Still though, does anyone know the max density of copper sulfate pentahydrate solution at room temp. I'm not a chemist and I couldn't find it anywhere. Copper...

True again, but sodium metatungstate goes for like $800/kilo. There is just no pleasing me right? The idea is to create a low-cost & fairly safe pressure equalizer with a column of fluid. A denser fluid means I can achieve the same pressure head with a shorter column. I don't want the...

It's really not much denser than sugar solution. Sugar water doesn't make you pass out if you breath in vapors either. Might be fun though.

Yes, but I'm not going to be taking a bath in it or be drinking it. I mean, I don't want something as toxic as mercury. I basically need something that I can survive through if it spills. It will take more than copper sulfate to kill me! Seriously, though, the non-toxicity is just an...

So I am trying to find a liquid at room temp., preferably with a low viscosity, non-toxic and non-acidic, that has a specific gravity greater than 1.5 and is fairly cheap. Tall order? I have done a little research and my best bets seem to be Copper Sulfate Pentahydrate, Zinc Chloride, or...

Ok, thanks! ...only I still don't quite understand why that is exactly. Why doesn't the standard l*g*density apply? My guess is it's because the water above the column is denser than the air column, correct? And so the water pressure dictates the air pressure, since the weight of the...
