That's a good suggestion. do you think It will be able to crumble if let it dry? I've used the oily modeling clay that never dries. I'm also looking at air-dry porcelain clay that you can make at home, but I need it to be breakable. I'm curious if I can add anything to it so that it's not so...

Hello everyone. I need a hand. I'm designing something special and I need some help to find a substance that I can make or buy that I can form into something the size of a baseball, and be able to cast an object in the center of it and be able to break it apart easily and cleanly to reveal the...

Thank you for your help. I like the idea of using a second sensor with a fixed aperture using the same light source to establish a baseline. I'm concerned about a photocell's effective scan rate. I know photocells take a moment to stabilize with a change in intensity. Do you think that might...

Greetings everyone. I'm working on a project that requires the very accurate measurement of distance varying between 0.500'' and 0.050''. I need to measure the distance within at most 0.010'' tolerance and give the value digitally. The read-rate is once every second. I'm on a very tight budget...

Thanks E.Bar.Goum, I appreciate your thoughts and links. I was worried the particle size would need to be incredibly small. At that rate, objects of any useful size would take an eternity to print. I was also hoping for a large scale application (several cubic inches). I don't suppose anyone...

Greetings PFers, Would it be possible to move microscopic particles of a wide range of composition (conductivity, density, etc...) using a directed beam technology? The idea is to have a fast 3D printing technology (practically no moving parts) that is capable of depositing of a wide array of...

Thanks for the input everyone! I decided to stick with dedicated RS232 communication through network cables for each of my devices. I'm sure I could've done something with RS485, but I wanted to keep the system simple. I was going to use an arduino Mega anyway, so there posed no problems with...

Greetings! I'm working on a project involving multiple different Arduinos spaced about 500 feet apart. I have a master Arduino which I plan on being an Arduino Mega and 5-8 separate slave Arduinos (probably Arduino Nanos) which feed basic data like switch values to the master. I would like to...

Unless I'm wrong, there isn't a way to make this demonstration work. Correct? -Tay.

The device would simply be turned on and the ferrofluid would be attracted to the energized field segments. Tuning the pulse widths to match the coil will be the trick. I admit the experiment is a bit of a stretch, but you could say that in about a bilionth of a second, electricity has...

Greetings PF. I've got an idea for a demonstration of the speed of light utilizing a pulsed electromagnetic coil and ferrofluid. I'm concerned with the feasibility of this project as it may push the limits of semiconductor technology. I would appreciate any insight on the difficulties of...

Thoughts anybody?

Greetings PFers, I'm working on a project where I need to focus powdered that is being blown through a tube. I would like to discuss the option of using acoustic focusing to guide the particles to the axis of the tube to prevent the particles from contacting the tube inside diameter. There...

I only expect a standing wave to be generated in the tweeter waveguide. With my current configuration illustrated in my last drawing, it would indeed be impossible to generate a standing wave parallel to the air flow without a cap at the bottom with a small orifice for the particle stream. I...

I've attached what I've got in mind for acoustic focusing. It separates the powder injector and focusing source from the heater chamber. The tubing is 1/4'' nylon. Any obvious problems? Thanks! -Tay
