Measure Skateboarding Device.


The concept is to use technology to physically reconnect with our bodies and our environments. The concept is to go skateboarding. The device tracks, measures and excels individual and communal progression in skateboarding.

Using an accelerometer located within a riser pad data would be wirelessly be transmitted to an application on a smart phone via Bluetooth. This data would be linked to the users Skateboarding social media profile where accumulated data would be sorted and displayed in the following categories; trick performed, trick speed, trick height. When the user preforms the same trick repeatedly trick percentages (consistency) and total number of tricks would be calculated.

Users with profiles could then be placed on a global ranking scale and could compete to be the best in the world.

The goal would be for this devise to be put into production and sold on a large scale to the public.

When the device is used in conjunction with a smart phone such as an iPhone, Google maps could then cluster what tricks where performed where and when. This would help with the skateboarding phenomenon of “already been dones”. Google maps would start to collect clusters of good skate spots. This would help individual skaters to find spots they have never been to furthering progression.

The system would allow individual skaters to track their progression and skills in a real-time. By allowing the skater to see/measure/track their skills/progression compared to others it pushes them to make more/bigger/more consistent tricks.

Skateboards are built to be very modular because they take a fair amount of damage and parts need to be replaced at different times. Riser pads are a piece of plastic that separates the trucks from the deck giving the complete board more height.  I have contained my electronics inside of a hard plastic riser pad that I’ve milled so there are no exposed parts. This project works because the user doesn’t have to do anything. Everything is done autonomously. All the user has to do is create a profile and go skateboarding.

Experience Prototype

i. User Buys device.

ii. User downloads App from AppStore and registers their account.

iii. User creates an account on the Skateboarding social media website and syncs App.

iv. User syncs phone with device.

v. Install Rider Pads on skateboard with four bolts.

vi. User is free to go skateboarding.

vii. When tricks are performed App syncs with online profile, and Google Maps.

viii. When board is inactive sleep mode initiates saving batteries.

ix. Data is now available online for all users to view.

Physical Prototype

In my prototype I’m using an Arduino Pro Mini, an accelerometer, Bluetooth Smurf Silver, and a Lithium polymer battery.

i. 3rd attempt at perf board circuit sucsessful. Included accelerometer, Arduino Pro Mini.

ii. BluetoothSmirf Silver (not the compatible Bluetooth Mate Silver) I had to jump the pins to make the proper connections.
iii. Lithium Polymer battery 3.7V.

iv. Completed Circuit.

v. 2 piece Riser Pads with bolts. I milled the center cores out of these so electronics could be

contained within but still provide adequate foundation for the trucks.

vi. Electronics Stashed in riser pad.

vii. Final prototype assembled.

Arduino Sketch

I have created an Arduino sketch that recognizes if a user ollies, and kickflips.
// these constants describe the pins. They won’t change:
const int groundpin = 2;             // analog input pin 2 — ground
const int powerpin = 4;              // analog input pin 4 — voltage
const int zpin = A2;                  // z-axis of the accelerometer
const int ypin = A1;                  // y-axis
const int xpin = A0;                  // x-axis (only on 3-axis models)
int sensorValue;
void setup()
// initialize the serial communications:
// Provide ground and power by using the analog inputs as normal
// digital pins.  This makes it possible to directly connect the
// breakout board to the Arduino.  If you use the normal 5V and
// GND pins on the Arduino, you can remove these lines.
void loop()
// print the sensor values:
// print a tab between values:
// delay before next reading:
Processing Sketch

Working from a tutorial I found here I was able to post to my Twitter account with a mouse click. I then combined it with code from the graph example and was able to create serial driven Tweets. The problem is that the posts go to my Twitter account anytime there is any data from the serial, which is every 100(millis). The accelerometer when at rest reads around 550 due to gravity, therefor a post goes to my Twitter account every 100(millis) instead of whenever a Trick is preformed.

I’ve added and if statement in relation to the zpin to try and control this but now Tweets have stopped all together for now. I am continuing to work this out with the help of users of the Arduino and Processing forums.

Grow Pockets!

Grow Pocket with Instructions

How to use the Grow Pocket:

Cut on dotted line
Water pouch contents thoroughly
Place seeds under thin layer of soil
Place yourself in a sunny area
Keep soil moist by walking in the rain

What to Grow?

Go to the garden store and find something that tickles your fancy! Is it Tomatoes? Purple Carrots? Spearmint? Flowers?

Anything can start in a Grow Pocket! If it your chosen item gets too big you can replant it in a public space, or in a pot at home. Pick something small, like mint or sprouts or herbs and you can enjoy it for weeks at a time.

Test Soil Pocket and Tools

I decided to plant some flowers in my purse!

The purse is a larger version of the Grow Pocket with a duct tape strap


The Grow Pocket is suitable for  breast pockets, purses, and jacket pockets. But it can also be worn on a belt, or on a bag, or its own strap. I tried to take soil spillage, and watering into consideration while constructing the pockets and selecting materials. The insert, or Soil Pouch has a special red line to demonstrate where to cut to assist in minimizing spilling, as well as to create handles to life the pouch in and out. The Pocket protector is waterproof, and durable, also being able to be folded up smaller, or closed with the flap.

Many Grow Pockets- No packaging required!

Mix and Match

Using the Grow Pocket with the contained Soil Pouch allows users to grow several plants in different pouches at the same time, and swap out to take different plants out for the day’s activities. You can bring your sprout pack when on the go, or you mint to have fresh tea! Or just brighten your day with your special pocket flower grown from a seed (and you’ll smell better too!)


Pouches can be easily clothes-pinned to a string hanging in a sunny spot, or placed in a window to continue to grow when not worn on the body. I imagine it next to your alarm clock, and sometimes in the shower.

Why Grow?

Many of us need to reconnect with the natural world, and remember the feeling of caring for a living thing. I want  to awaken the humbling experience of planting a seed, and watching it grow into something beautiful, and edible. Will you keep it, or will you set it free?

“… and my flower wasn’t like all those other flowers…”

And can these little seeds survive our busy schedules?

What kind of seeds do you need in your life? Soothing chamomile? Simple moss?


The Grow Pocket is made out of simple materials. The outside is a clear shower curtain (Honest Ed’s $1.99) which i chose for its fabric-like quality, and the inside is black landscape fabric (Summerhill Nursery and Floral $29.99) which is actually quite lovely, and easy to sew. However, I also played with plastic raincoats, duct-tape, organic ground cover, peat-moss pellets, organic pots, and garbage bags,tin foil,  plastic tubing, clear tape, recycled water bottles, and soil, lots of soil.

My sprouts/ test subjects are Organic Speckled Pea Shoots. Which are a delicious micro-green that can be nibbled, or added to salads. I also picked up some lovely Kalanchoes (aka. the purple flowers) to brighten the purse and welcome spring!



Working Prototypes and Concept Exploration

Duct-tape prototypes for different pocket sizes

Belt prototype using only landscaping fabric. Surprisingly holds water well, allows plants to breathe. Durable fabric.

Plastic belt pocket. Clear viewing area to view roots growing!

1st Plastic pocket protector design with Rain-catcher prototype for easy watering.

Rain catcher in action. It totally works! There is a wire in the middle that allows it to bend toward the rain.

Pouch exploration- different sizes and shapes.

Sewing Pocket Protector is very simple.

Bra with pockets for enhancing cleavage using soil and moss!

Root viewing underwear before being filled.

Root view undies strap detail

Root viewers with soil and organic cover to hold soil in. This is a messy pair o bottoms. Not the best idea.

Organic bottom concept to connect our pubic hair to the roots, and physically connect ourselves to the plants.

I started this project by researching, and measuring traditional pocket sizes, and finding unique locations on the body to plant on. I wanted to explore pockets, but I also sought out the best kind of wearable for being outside in the sun. Which is why I did a small series of sunbathing outfits such as a bikini top and bottoms. I also explored the idea of catching rain, and natural irrigation using bodily fluids, however decided to keep it simple and just focus on growing! I am really really happy with the final Grow Pocket design, and overall successful completion of my intended design brief, and political agenda. I would like to receive feedback and images of the prototypes I distributed to the class, and maybe make another version utilizing the traditional properties of plastic, such as melting or fusing, instead of sewing the layers together.

Over the summer I would really like to continue to create unique pieces that push the boundaries of  “wearable technology”. In studying this new field for the past 8 months, i feel as though I  have found an interesting area of opportunity for non-electronic applications of “technology” that would  be ideally suited for, and  worn on, the body. I’m really enjoying the exploration of natural elements to influence our clothing, and reconnect us with our primal need to interact with the natural world.

The rain-catcher was not explored as completely as I would have liked to, and I see some potential for sculptural and functional jewelry- esque pieces. Also with the rain-catcher concept came the idea of a irrigation suit for the body, and I think that I would actually like to create the garment (as more of a conceptual showpiece like Smell + by Loiseaux). I have actually purchased all the materials to do so, and have started to lay out the piping, and tubes in a similar way that i would have layed out an electronic circuit (which is actually quite amusing to me).  Thanks for an amazing semester everyone! I will leave you with a little teaser…
