Ultrasonic Transducers in a cool-mist humidifier / fogger

Submitted by mitchellfchan on Fri, 02/26/2010 - 14:40

 Hiya!

So, I'm trying to make some mist. A friggin' lot of it! Now, I know that there are whole bunch of different humidifiers or fogger mechanisms that I can buy online, but building them myself offers the advantages of affordability (I'm going to need a whole bunch of those things) and of being able to customize the size/shape of themodules to fit inside a larger mechanism.

Of course, I have a couple problems.

A student is interested in measuring the force of impact of a large, padded, blunt object on a human frame. Three ideas came to mind.

  • Force sensing resistors, FSR's
  • piezo film
  • accelerometers

Alternative energy revisited - SOLAR 1

Submitted by Ed_B on Fri, 02/19/2010 - 17:23

 

I'm working on a project to see what kind of solar experiments we can add to our curriculum. I'll be looking at different combinations of loads and supplies on my workbench. To make sensible comparisons between different device configurations, I need some baseline figures on available light in different environments. Here ia a bit of raw data that will be essential in comparing the behavior of different devices under different lighting conditions.

Light intensity measurements made with with a Sekonik Studio Deruxe II meter (Thanks, Anna). Outdoor measurements made noon, February 19, 2010 at Chicago, IL, 41.88 deg North. (Ed Bennett, sbennett@saic.edu)

Mitchell Chan "A Vision of Amen" 2009

A Vision of Amen

This piece uses the prototype of the ArtBus PWM board.

Statement from Make Online:

"The project on display in the video is titled "Visions of the Amen" by Mitchell F. Chan. It's being brought to life by the voice of talented young soprano Ashleigh Semkiw. It's a kinetic sculpture in which strings, weighed down on one end by brass bars and attached at the other end to motors, spin at various speeds to sweep out those ghostly sine-wave forms, and pull up and down on the brass rods. The resultant visual effect, overall, looks something like 16 brass rods dancing, bobbing up and down in a forest of ghostly columns.

Each string in the arrangement is activated by a different note, and spins with a velocity dependent on the volume of that note. So each song and unique delivery creates a different ballet. The microphone feeds into a software that I wrote in Processing, which does some pitch and volume analysis, and then exports PWM values for all the motors via serial protocol to a set of microcontrollers. I originally set it up with Arduinos, but I found that for addressing multiple controllers, the protocol was simpler using the new ArtBus controller being developed at the School of the Art Institute of Chicago.

Add a Flash Movie

Submitted by Ed_B on Wed, 02/17/2010 - 20:44

Here we are, adding a movie. It is 400x300 and 15Megs maximum. This isn't the normal way.

First, we'll upload a Flash movie as an "flv" file: BenCassieSp08.flv

The upload flash button is here:

Click the Upload tab in the pop-up browser, then upload your file.

What next?

With the growing number of hardware projects cropping up around the school, epsecially in the form of manufactured boards, there seems to also be a growing interest amongst both students and faculty to have more "off the shelf" solutions to specific engineering problems. What seems needed then is both a "single problem, single board" approach, as in single purpose boards that address one function, and also a "complex problem, many boards" solution, wherein many single purpose boards are modularly integrated to solve a more complicated task.
