That's a great idea and I think I have some silicone caulking and cornstarch available!I thought you could add colour to the mould, and it would be incorporated into the concrete.Thanks for posting! :-)

I think the jitter in the servos is due to errors in the timing loops used for the servo pulse timing. It looks very similar to the problems I had operating servos from my 6502 based BBC micro a few decades ago! :-) Maybe add a 16 servo dedicated driver board?

Can I just say that the two intersecting circles is just brilliant! Thanks!:-)

You could stick copper tape to the Kapton and etch it into multiple conductors. :-)You would need to loop round with ribbon cable to keep the current going in the same directionOr!If you made a loop like a normal speaker coil on a long length of Kapton and made two yolks with two gaps with fields in either direction and put the top of the loop in one and the bottom in the other, they would both move sideways in-phase like your isobaric speaker!(I hurt my wrist while trying to verify that the motion would be in the same direction if field and current were both reversed. :-))

This is Great! :-)Could you increase the magnetic flux density over the ribbon by using a ferrous metal yolk connecting the backs of the magnets?Maybe made from an old tin can. :-)

There are only three wires going to the Cube, 5v, ground and data.A small stereo jack socket could be mounted in the corner of the cube and a plug mounted on the base.The jack plug would work as a (Possibly terrible) comutator and allow the cube to be rotated.I would protect the power in the cube with diode.I would put something in place to prevent the cube being unplugged to stop the power and data lines being reversed as the plug slides past the contacts on the jack socket.That could lead to "Infinity Smoke" :-)

Machine tools used to be hand operated. Then, motors and electronics were added that allowed them to be controlled by numbers punched into paper tape.This gave us Numerically Controlled tools.Later, the tape machines and then the electronics were replaced by more sophisticated computers and we got Computer Numerical Control.CNCThis may seem like ancient history but I replaced tape readers on NC machine tools in the 1980s and 1990s! ;-)

I'm very impressed by the way you decided what you wanted and then went right out there and made it.Great work! Terrific final product! Well Done! :-)(After reading all the safety advice in the comments I have cut off all my hair and thrown away my gloves and scarfs on the off-chance that I ever use a belt sander. ;-)

Hi!Thanks for this instructable, You have made a very nice box and the parts inside are well put together and clearly achieved your goal.I am surprised by the amount of argument about the name and structure of the gas prioduced.I think the main point is that the gas produced is explosive.This is not the same as simply flamable.Propane and butane are flamable gases that can be stored and shipped safely by preventing them coming into contact with oxygen until they are to be burned.Hydrogen is the same.If the hydrogen was collected seperately and stored is a container without any other gas (Say, by filling it with water and inverting it is a container of water and bubbling the hydrogen in , thus displacing the water in the container.) the hydrogen would be relativly safe. It only burns when …

This confirms my observations over many years of building my own computers.The only thing with lasting value is the case! :-)
