If I had more time...

Posted on December 20, 2005 at 03:18 PM by sj695

NOTE: Shout outs after the jump

Already, we’re ¼ of the way done! WOW! How do I feel about this? How do you feel about this? In some ways it’s kind of sad, but I am sure glad to be done with finals!! At the same time my mixed feelings towards being a quarter of the way done is also reflective in my finals. Although, they were stress filled and often error prone, especially wireless Ping Pong (Kate Hartman ROCKS!), I found the experience very stimulating, motivating and full of adrenaline. Actually after finals I felt this void and I found myself waking in the morning asking “now what?” and then that’s when the sadness (stress?) kicks in because in 3 more semesters that “now what?” will no longer be a whisper greeting me at sunrise, but a scream echoing through my dome. Carpe diem and live in the present little Steven, at least a little bit.

So now what? Maybe I’ll head over to the list and check out movie and book recommendations, helloooooooo anybody theeeeeeeere. Or maybe I’ll help Dan Phiffer with his KICK ASS remix of floor 4, . Oh, oh I’ll get on dodgeball and find some people to hang out with, damn I forgot I broke my cell phone at the last TNO, NOTE TO SELF: Burn some candles and rub ya Gris Gris bag. And then comes that voice again “If I had more time, If I had more time I would” are final presentations coming back to haunt me?

STORYBOARD FOR DIGITAL VIDEO

WITH LISA, DAFNA, KATE

THE GREAT BAKE (title subject to revision)
an up-close & personal baking experience with a 70s science class filmstrip flair dramatic food action shots paired with awesome ground-shaking sound effects

*there will be no dialogue
*there may be dramatic narration [National Geographic-esque?]
*the natural speed of shots will be exaggerated
*the tone will be playful
*the completion of the cookies will be treated as a monumental achievement

Re-Paddling

Posted on December 15, 2005 at 04:51 PM by sj695

We decided it was best to redo the paddles all together, so we both went to Paragon at Union Square and bought 5 dollar paddles to break apart and Piezo buzzers at Radio Shack. The Rubber on the paddles were stripped open as well as the wood on the handles.

The Peizo buzzers were soldered, red is to power, blue is to analog and black is to ground. Then a hole was cut in the middle of the handles as shown in the pictures in order to place the wires that go from the peizo buzzer to the transmitter boards.

After making the hole, the Piezo Buzzer is placed under the rubber ever so carefully as the wires of the Piezo buzzers are very very sensitive and glued with the gorrila glue. The new buzzered paddles are clamped down and left to dry overnight.

The reciever box was re-designed to be more accessible and to look more prefessional and the transcievers are now placed in a little pouch.

I have to say I was glad we redid the paddles because it gave me a chance to see how the paddles actually worked and what was really used to get data from the paddles to the pic chip. Speaking of pic chips, the pic chips for the transmitter boards were changed from the larger 18F452 to the smaller 18F252 which has 28 pins. It was best to use a smaller Pic chips since we were using a smaller breadboard and we needed more space on the board to fit everything together.

Below are few pictures of our preparations:

Ping Pong - The Remix

Posted on December 08, 2005 at 04:50 PM by sj695

We finally got the Paddle to work wirelessly, and we have figured out how we will be strapping the paddles. What we have decided so far is to mount the breadboard and having these velcro straps wrap around them We hope to get everything done by this weekend so we will be able to do some userbility testing and be able to video tape the users in action! Below is the code we did.

Ping Pong - The Remix

Posted on December 01, 2005 at 04:36 PM by sj695

We’ve decided to make the signal digital rather than analog because there was too much data being sent through, so it was much easier to have it digital.

We also have a back up plan….IN CASE the WHOLE WIRELESS thing doesn’t work out, and it’s to combine everything in one big box. Since we are still getting some signal difficulties.
