Description

A bunch of bezier that moves in a very beautiful and tranquil way, with sound. Sort of like an audio visualization.

Getting it to work with the sound when certain keys are pressed.

In order to make our ping pong to work wirelessly, we have decided to use plain old Radio Frequency (RF) Serial Communication. RF transmitters sends bits on pulses of radio energy, and what attracted us to RF frequency is it’s flexibility. RF unlike Infrared serial is omnidirectional and can go greater distances, even through walls. This makes it great for our ping pong application, because as you saw in last week’s Ping Pong video there were lots of acrobatic movements going on. RF is also much easier to program compared to bluetooth. So hopefully we will be able to save more time.

In order to differentiate the signal from ambient radio or light waves, the data is sent on carrier wave. Actual information is encoded by slightly varying the frequency of the carrier wave (FM) or signal strength (AM). We will be using 315MHz.

What we have so far:

Laipac Transmiter & Reciever

The coding that we have so far, but still needs to worked on as we are picking up other signals we don’t want.

inbyte var byte ‘ incoming string
outout portb.1 ‘ status LED
output portc.6 ‘ serial out to PC
input portc.7 ‘ serial in from reciever
n_2400 con 16780 ‘ baud mode for serin2 (2400-8-N-1 inverted)
n_9600 con 16468 ‘ baud mode for serin2 (9600-8-N-1 inverted)
i var byte ‘ loop counter

RFSerialIn var portc.7
PCSerialOut var portc.6
StatusLED var portb.1

‘ flash status LED to start:
high StatusLED
pause 500

main:
‘ this serial call does nothing until it gets bytes:

‘ high statusLED
‘ if the first three bytes are “OBJ”, then
‘ the fourth byte is data. parse it as a number (DEC inbyte (3))

The final product of our video assignment. We were all given a chance to edit the video using Final Cut Pro and met up in as group after and decided that the cut Demetri’s rough cut was the best. So we worked with that. I had a load of fun on this assignment. Well waking up really freakin’ early to shoot in the library wasn’t much fun, but the whole experiance of running around the village and getting random people to be in our video was fun. The funniest bit was definitely the bathroom scene. We shot that scene in the boys bathroom in the basement of the Tisch Building. We girls, Wendy, Nana, and I couldn’t stop laughing. It was great!

Our idea is to re-create the ping pong application, and make it wireless this time. As we all know it’s always hard to jump around like an acrobat playing ping pongs with long tangled wires attached to the paddles. So this is our solution, going WIRELESS!!
