An addition to Arduino

•October 15, 2008 • Leave a Comment

I would probably need to add this to my Arduino to make it work better. Also, I plan to use RC Servo motors as the output for this project. I can program them easily and it could be more meaningful. Here is a link of a motor shield that could be really useful.

Research Areas

Came across this link. I thought that it was really useful, because technically it is measuring infrasound that soldiers can be exposed to. With more research in this area, it could have even more implications/uses for the future.

Progress with Wii and Arduino BT

•October 12, 2008 • Leave a Comment

I have successfully managed to get my Wii controller to send data to the Arduino BT. That is quite a relief, as I was not sure if it would really work. What I am doing is sending the accelerometer data to the computer via bluetooth into Processing. Then from Processing, it communicates to Arduino, where the data is sent via the Bluetooth Serial port. Detailed information to come soon, with pictures.

Wii Experiment

Hacked into the Wii Remote, since I will be using the accelerometer. First step was to remove the plastic casing, which provided the first problem: How to attach batteries to it without the plastic casing. Solution was to get a battery pack. Partial success, it works without the plastic casing, but the connection right now is a little flimsy, so will have to solder the connections in. Below is a picture of it.

Wii

I’ve bought the Nintendo Wii controller. Realised that the best way to try and sense any low frequency sound waves would be by using an accelerometer…and the best device for that would be the Wii controller. It’s already up and running, got it connected using DarwiinRemote. Now the next step is to build the device in which the Wii controller will be placed. After that I would experiment and see how it can pick up the sounds. From the looks of it, I will have to remove the plastic casing from the controller so that it becomes more sensitive.

T.S Eliot – The Waste Lands

I was reading The Waste Lands by T.S Eliot and it got me thinking of the environment that man has created for himself through the course of evolution.

Here are some excerpts which I have been reflecting on:

“A heap of broken images, where the sun beats and the dead tree gives no shelter, the cricket no relief”

“Unreal city,

Under the brown fog of a winter dawn.

Sighs, short and infrequent, were exhaled,

And each man fixed his eyes before his feet”

First Experiments

Tried some experiments today with low frequencies and 2 speakers. I used cheap speakers and PD to simulate a low frequency environment, to see how the speakers respond. This is important if I am to use speakers as tactile transducers. Here are some observations:

  • The diameter of the speaker needs to be quite large, so that the force of the low frequency can be translated effectively.
  • The speaker of about 2 inches in diameter can respond to 50 Hz, so based on the above observation, a  larger diameter should have a better respond at about 20Hz or slightly less.
  • Using small speakers would be out of the question, as they seem more responsive to slightly higher frequencies, usually above 100Hz.
  • Cheap speakers can’t be used 🙂
