The basic mode is for the etextile beginner to create a tiny, quick, and
low-cost project.
In this mode, Sparkle connects to
plain LEDs and runs on a small CR1216 battery for 12 hours.
However, it can't sense the environment, power motors or play music.
|
How do I connect it?
-
Connect Sparkle to the battery holder using conductive
thread,
conductive
paint, or regular wire.
- Use two seperate threads, one for plus and one for minus.
- Go through each hole 4-6 times to make a good connection, not
just once
- Make sure there is no short circuit
- Insert a 3 volt battery. It should start flashing.
- Next, with the power on, add the two LEDs on the left.
- The one closest to Sparkle has its + side up, and the
outer one has its + side down.
- Use two seperate threads, one for plus and one for minus.
- Make sure these two LEDs are also flashing before adding the two on the
right.
- You can use other LEDs, up to 20, in any color combination.

It's not turning on at all
The tiny red light never goes all the way off: it stays on
when Sparkle is running, flashes rapidly when waiting for a program, and
flashes once per second while sleeping.
If you cannot see this light at all,
try a fresh battery and double-check your connections. Look for places where
two threads might be touching.
If you can't quickly figure it out, it's best to totally undo the circuit,
and sew only two things: Sparkle, and battery. Once this works, you can
start adding other leds, one by one, testing each time you add one.
|
The tiny red LED is on, but nothing else
In this case, the first thing to do would be to reset Sparkle,
to make Sparkle's center light flash:
|
- turn Sparkle over
- connect the plus and minus holes to a 3V battery
- briefly connect the reset pad to the reset hole with tweezers or needle
- wait 1 second
- repeat steps 1-3 until Sparkle's center flashes again
- You can do this even after the project is sewn down, just use a pair of
tweezers.
|
|
How do I turn it off?
- Hold your pinky, a needle, or tweezers to the strip under the tiny red LED
- After 1 second, the tiny red LED should start flashing
- Keep your finger on the touch strip for more than 1 second
- The red LED will fade off, and Sparkle will go to sleep
- Press the touch strip again to wake it up.

How do I program it?
- Hold your pinky, a needle, or tweezers to the strip under the tiny red LED.
- After 1 second, the tiny red LED should start flashing.
- Put Sparkle in front of the icon on the screen and press send.

It doesn't enter programming mode
The touch strip measures the capacitance in your finger. It might help to
use a needle or paperclip for better contact. Moistening
your finger works too.
|
It's not getting new programs from the screen
- Hold Sparkle closer to the screen.
- Make the screen brighter or change the contrast.
- Dim the lights; a brightly lit environment overpowers the sensor.
-
If your web
browser is playing a video or doing some other activity, it throws off the
timing.
Close all other browser windows and see if this solves the problem.

What kind of programs can
I create?
Choose a flashing pattern and speed from the NORMAL side.
The SPECIAL menu doesn't work in basic mode.
You can also use Airtext in this mode to create a
persistence-of-vision (DISPLAY).

The featured mode is for the etextile enthusiast who wants to
add sensors, motors, and other devices to make more interactive projects.
In this mode, Sparkle's center light will not flash: it sends all
flashing data to the lightboards, though the tiny red LED will be
lit.
All components (sensors, lights, motors) have a
tiny microcontroller that allows them to communicate with Sparkle,
so you can interact with the different sensors and actuators without
writing special code to deal with each one.

How do I connect it?
-
Connect Sparkle to the battery holder using conductive
thread,
conductive
paint, or regular wire.
- Use two seperate threads, one for plus and one for minus.
- Make sure there is no short circuit
- Insert a 3 volt battery. It should start flashing.
|
- while it's still connected to the battery, turn Sparkle over
- briefly connect the reset pad to the reset hole with tweezers or needle
- wait 1 second
- repeat steps 1-3 until Sparkle's center stops, but the tiny red
LED stays on
- You can do this even after the project is sewn down, just use a pair of
tweezers.
|
- Next, with the power on, add a lightboard (with single dot) to the right of
Sparkle
- Use two seperate threads, one for plus and one for minus.
- Make sure lightboard plus is connected to the top right hole on
Sparkle
- Make sure lightboard minus is connected to the bottom right hole on
Sparkle
- Go through each holes 4-6 times to make a good connection, not
just once
- When this lightboard is flashing, add the other lightboards in the
same way
- You can connect lightboards on either side of Sparkle
- You can use up to 20 lightboards, in any color combination.
- For sensors, the text is the plus side
This system uses the same pair of wires to connect all the pieces,
which reduces the chances of short circuits - very important for
a 3-dimensional medium like clothing.
As a result, these sensors work only with lightboards, not with regular
LEDs, and you can use only compatible components (most likely from our store).
Furthermore, this mode uses up more energy, so you'd need a large CR2032
battery or 2 AA batteries in series.
3 volts only.

If you cannot see this light at all,
try a fresh battery and double-check your connections. Look for places where

Look to make sure all the lightboards have
their pluses connected to the top left (or top right) holes on
Sparkle, and their minuses to the bottom left (or bottom right) hole
on Sparkle. Do the same for sensors: for sensors, the text indicates
plus.
If you can't quickly figure it out, it's best to totally undo the circuit,
and sew only two things: Sparkle, and battery. Once this works, you can
start adding other lightboards, one by one, testing each time you add one.

Sparkle is flashing,
but the lightboards are not
In this case, the first thing to do would be to reset Sparkle,
to make Sparkle's center light STOP flashing. You want only the tiny red
LED to be lit.
|
- turn Sparkle over
- connect the plus and minus holes to a 3V battery
- briefly connect the reset pad to the reset hole with tweezers or needle
- wait 1 second
- repeat steps 1-3 until Sparkle's center stops, but the lightboards flash
- You can do this even after the project is sewn down, just use a pair of
tweezers.

|
What sensors
can I use?
Sound, light, temperature, custom (connect to fabric sensors),
accelerometer, and touch.
You can use one sensor from this picture AND one touch switch in
a project, but not two sensors at the same time.
|
The custom sensor senses resistance, so you can connect (e.g.)
resistive fabric to the two holes to make a pressure sensor, or stretch
sensor.
Its built in resistance is 100 kilo-ohms.
|
|
|
The accelerometer normally measures movement, but if
you connect these two holes,
it will detect 1 of 6 orientations. Tutorial coming soon.
|
|
With this switch, Sparkle can react to your touch. You can also connect the
hole on the side to a patch of conductive cloth to create a larger touch pad.
|
|
|
Because sensors need to communicate with Sparkle, we have to use lightboards
instead of plain LEDs or sequins. Each one
has an ID (1-5), marked by the number of strokes or dots it has.
Connect up to 20 in any color combination.

What kind of programs can
I create?
Choose a flashing pattern and speed from the NORMAL side. Then
choose a pattern, speed, and repetition from the SPECIAL side.
To make Sparkle act like a sensor meter (turn on more lights when
there's lounder sound or higher temperatures), choose this screen.
|
Detect a wide range, like
completely dark to very bright.
|
Detect a small range, like
changes in room temperature.
|
Set a high threshold, so Sparkle
responds only when it gets really loud.
|
|
|
|
Turn on only one light at a time.
|
Turn on multiple lights, like a sound meter.
|
Turn off the lights as the sensor gets louder.
|
| |
Light up to match the current sensor value.
|
Light up briefly only when there is change in sensor value.
|
| |
There is also a textual programming language, so you could
write simple programs like these:
(always
(if (touched)
(twinkle 2)
(center 30))
|
(always
(if (> sensor 5)
(twinkle 2)
(center 30))
|
This tells Sparkle to
do the twinkle action when you touch the touch sensor,
otherwise glow its center light slowly (30-second duration).
|
This tells Sparkle to
do the twinkle action when the sensor
level rises above 5,
otherwise glow its center light slowly (30-second duration).
It doesn't matter if it's a sound sensor,
light sensor, or accelerometer; the lights will flash when the level of
sound, light, or motion rises above a certain threshold (the minimum is
1 and the maximum is 10).
