Hi, I managed to upload a lot of files including a low resolution video to the server this morning. The high resolution video is only half loaded. Here is the URL to my site. Enjoy. http://void.arch.usyd.edu.au/~andrew/infodevice/students/Cyclone/Home.html Cheers, Kim Continue

Hi, I think Dan is right. Andrew's site seems to have reached it quota as I have been unable to upload my files in the last hour - I was able to do it yesterday and as recent as this morning. Has everyone uploaded their sites? Unless Andrew gets an increase in disk quota soon, I won't be able to put my files to the site. Does anyone have any suggestions? Cheers, Kim Continue

Hi, I haven't settled on a name for my project yet but I'll use Cyclonic Beads for the time being. The challenge I encountered so far is not how to create a cyclonic effect within a rectangular column - I think I can achieve that. I have received delivery of some powerful fans and I will test them this evening at the tutorial. The problem I had last week was how to control a 12V power-hungry CPU fans using the Arduino board. I can't use the Arduino board to drive these fans as they run on 12V… Continue

Hi, I decided to start with a design that has all the features I desire then work my way through to pare back or change the design if I encounter technical challenges that are too difficult to overcome. I got my inspiration from snow globes and looking at images of Venus which is what scientists think Earth will become when we have a runaway greenhouse effect if we don’t manage our environment and resources responsibly. The centrepiece of the design is a globe illuminated from inside that is h… Continue

Hi, For tutorial 3, I connected a switch, a light sensor and an LED to the arduino board. The light sensor controls the brightness of the LED, ie when the sensor detects light, the LED goes bright and when the sensor is blocked, the LED goes dim. The switch is to reverse this operation, ie when the sensor detects light, the LED goes dim and w… Continue

Okay. I have uploaded my video to this post (see below).

I connected a switch to a digital pin and declared it as INPUT, then I connected an LED to another digital pin and declared it as OUTPUT. I wrote a sketch to read the state of the switch and blink the LED if the switch is pressed. I also added a potentiometer to the circuit and connec… Continue

You will find my research paper presentation on My Page. The 3 research papers I chose try to solve an technology issue that hinders wider adoption of mobile phone as a personal mobile device. Continue

Before I started writing the sketch, I had analysed the requirements and thought that I would need to handle input error. The tutorial brief states that the LED has to flash as many times as the number read from the serial port. Although the brief does not specify a valid range for the number, it should be greater than or equal to 0. If the input is not numeric, the LED shouldn't flash but I thought it would be nice to let people know that an invalid input was read. So I decided that the device… Continue
