ITP: Project Development Studio

Dream Jammies page is up, a refined description of the pajamas.

Here is a graph of my sleeping data from the pajamas:



iPhone app is done and working. I must say, it was exhilarating getting
the app working on a _real_ phone. And the fact my clothes and phone
were chatting...

The incredibly useful Lilypad Xbee!
Here are a few photos of the pajama prototype circuit.
I'll sew this into a black pair of pajamas for the first version.







For the show I'll be working with these organic cotton pajamas...
adding a bit of crewel embroidery for character.

The diagram above is actually for an extended version of the dream
jammies I'm working on, but you get the point. Under the left armpit
will be the lilypad xbee, under the right is the battery. In the middle
is the vibe board and an accelerometer, although I'm slightly worried
whether the vibe board will effect the accelerometer's readings. We'll find
out. The temperature board is close to the armpit for a better reading.
Everything will be insulated so you don't feel hard parts - particularly
the armpit areas.

I'm going to put my money on developing an iphone app. I spent my time
last class doing research, and I've made progress programming. For
midterm I have ajax code which I can use to demonstrate. The lilypad
xbee's arrived which is terribly exciting. Rob Faludi has been
extremely gracious in coordinating the order and generous with his time.
Thanks Rob! I have the prototype belt which will go into an existing
pair of pajamas at least halfway there, but I need another day to finish
it up.

- xbee note: don't forget to tie VREF to VCC for analog readings

Here are some useful links for xbee stuff:

"In order to upload new firmware to the board, you need to make an
additional wire connection to the XBee module. Connect a wire from GND
to pin DI8 on the XBee Board. Without this connection, the upload will
not succeed."

Indeed. DI8 is Pin 9.

So far, here are my xbee settings for the pajamas:

COMPUTER MODULE:
ATID556 --> PAN ID
ATMY2 --> my address 2
ATDL1 --> destination address 1
ATP0 --> PWM mode (pin 6, receive from D0)
ATD1 --> Digital out (pin 19, transmit to D1)
ATIU1 --> I/O output enabled
ATIR --> sample rate 20 milliseconds (hex 14)
ATIA --> I/O from all FFFF
ATIT --> samples before transmit 5
ATWR --> write settings to firmware

PAJAMA MODULE:\
ATID556 --> PAN ID
ATMY1 --> my address 1
ATDL2 --> destination address 2
ATP0 --> RSSI mode
ATD0 --> ADC mode (pin 20, transmit to PWM0)
ATD1 --> digital in (pin 19, receive from D1)
ATIU --> I/O output enabled 1
ATIR --> sample rate 20 milliseconds (hex 14)
ATIA --> I/O from all FFFF
ATIT --> samples before transmit 5
ATWR --> write settings to firmware

alright... time to get busy...

1. make a schedule

2. build a mockup

3. get dirty

hurm, which dainty should i start with first?

pajama parts:

battery
many accelerometers
xbee

computer side:

xbee
software

remote:

iphone
prog for send/recv vibration

As was mentioned in class: is the best way to express the partner
sleeping through a rendered image? Should I move a stuffed animal
according to show she is sleeping? (erm, I don't think so) Could it be
as simple as my phone vibrates as she moves?

Also, what sort of outputs should I make through the "stuffed brain" of
the pajamas? If she is having a nightmare, maybe I can intervene to
wake her up somehow? A pleasant scent? Warmth? A shock? (j/k) A
little voice in the morning which says, "don't forget your phone?"

There are also, of course, other interesting things to monitor. Blood
pressure, muscle tension, dream state, and so on...

I think I need to start simple:

1. add an accelerometer to jammies, trying recording data
2. have a phone vibrate when the jammies move
3. this means I need to get xbee down as well a bit of iphone coding
4. develop the "brain" (what type of stuffed animal and why?)
5. what to do about power?

I need to get these three done in the next month. So say, by 10/22.

I'll work on 1-3. in class.

Project Development Studio

We are in the initial phase of developing a project for the class...
where better to start than with a dream?

Dream

To connect people across thousands of miles.

Vision

Across multiple time zones, it is often day for one person and night for
the other. I seek to passively connect people even while they are
sleeping.

Goal

To sew a pair of pajamas which will be worn while sleeping. The pajamas
will include sensors to read the position of the body. This position
will then be "painted" in real-time to present a surreal picture
viewable by another party online.

Plan

Buy a pair of pajamas, wire them up and see how I can do for
positioning data. Start working with openframeworks for the
visualization. A stick figure imposed on a photo of a real place will
do for starters. Once these two parts start taking shape I will work
on furthering the pajamas, technically and aesthetically.
