Poiesis / Tumult - Putting cataclysmic storms in meditation

Read about the collaboration in Fast Company. Also exhibited at the Frieze Art Fair 2014.

New York-based visual and performance artist Lia Chavez approached us for a one-of-a-kind collaboration. Lia works with multimedia to explore the behaviour of light in a state of meditation, and instead of a still, calm and quiet place, she's discovered that deep meditation can in fact trigger visions of stroboscopic light and cataclysmic storm systems. She wanted to share this visceral experience with others, so she came to me and rehabstudio to help create her next piece: an 8-hour live performance in Dundee, Scotland and the Frieze Art Fair in London.

I created custom code that reads Lia's brainwaves and, via bluetooth, transmits its signal to a strobe light. The signal's frequency and strength adapted, so that when Lia is in a deep state of meditation, the strobe flashes brightly and intensively, and less so when she is in intermediate states.

Lia's final performance turned out to be the perfect meeting of technology, science and art that inspired us all to collaborate in the first place

Flood Beacon - Real time flood level data and alerts.

Visit the website here.

Read about Flood Beacon in CNet, TechFaster, Tech City News and Postscapes

Flood Beacon is an internet-connected device that broadcasts real-time flood level data and alerts.

The risk of flooding is increasing.  Flood damage losses are expected to increase four fold by 2050, costing $1 trillion globally. Unfortunately in dealing with this growing problem, those at risk have to rely on predicted flood information, rather than real-time information. Flood Beacon aims to address this failing by providing flood data and warnings in real-time.

The Food Beacon is engineered to broadcast live data such the current water level, GPS location and any sudden accelerations the beacon may feel. The data is sent to cloud for processing and distributed via an open API, managed by Xively. Alerts can then be sent to our smartphone application (push notification when someone is in immediate danger), monitoring stations or anything else people wish to develop.

The prototype hardware technology inside includes a GSM chip for communication, microprocessor, accelerometer, ultrasonic sensors, rechargeable LiPo battery and a 3D printed design.

BitTag in retail

Visit the website here.

Read about BitTag in the BBC, PSFK, Yahoo Tech, Cnet, Vice Magazine, Creative Online, IBTimes,, Postscapes and live CNBC

BitTag is a physical price tag that creates a seamless integration between Bitcoin (or any another digital cryptocurrency) transactions and "bricks and mortar" retail stores.

Once set up, the BitTag hardware displays information such as the product name, price in USD (or other local currencies) and the real-time price in Bitcoin. If the Bitcoin value suddenly fluctuates, the price on BitTag will instantly reflect this. The customer, therefore, instantly knows how much the item is worth, whilst the retailer does not incur any financial loss if the value of the Bitcoin changes.

Each BitTag is managed with the assistance of an accompanying iPad app. The app can either be used to setup the Tag or process the digital Bitcoin transaction by simply placing the BitTag on the screen. Alternatively, the Bitcoin transaction can be activated by a simple 'shake' of the BitTag hardware, enabling a Bitcoin QR code to be displayed on the OLED display and scanned by the user's smartphone, using standard apps like BlockChain.

The prototype hardware technology inside includes a Bluetooth low energy (BLE 4.0) chip for communication to and from the app, Microprocessor (similar to Arduino), OLED display, accelerometer, rechargeable LiPo battery and a 3D printed design.

Adaptive Storefront - A creative vision for physical shopping displays

Reported in the PSFK Future of Retail report 2013 - read the article here

Shop windows don't have to be a passive experience. As part of PSFK's Future of Retail Report, me along with rehabstudio developed, designed a prototyped an interactive display that adapts to whoever stands in front of it.

The technology identifies shoppers using Bluetooth low energy (BLE) and instantly reacts to a set of personal data stored on their mobile device, such as shopping habits and preferences. Shoppers can swipe through personalised content, place items in a digital shopping cart, and purchase straight from the physical display.

This concept could be deployed outside the context of a store environment, be it street on physical billboards, bus stop signs or car showrooms.

Google Converse Arduino-powered Hack-a-Chuck

Project developed by me for rehabstudio for Google+ and Converse

// Coded and hardware designed and made by myself | part-creative input

Converse asked us to hack their sneakers, so me along with rehabstudio set out to create the ultimate personalised pair of Chuck Taylors.

We inserted an accelerometer X+Y axis, pressure sensors, Arduino microcontroller, and batteries inside each shoe, so that they would track the wearer's moves, and send the corresponding data wirelessly to a computer, which rendered colourful graphics projected onto a screen.

These graphics could then be printed onto a new pair of Chucks, for a truly personalised design that's entirely unique to how the wearer moves. Our hacked sneakers premiered at Cannes in 2013, where they picked up the silver prize in their category.

BLE Bike Lock - Unlock your bike lock through technology. No need for a physical key.

This Bluetooth low power 4.0 (BLE) bike lock removes the need for a physical key and enables greater convenience and safety for you and your bike. Once digitally paired, the lock remembers your smartphone. When you approach, it'll automatically unlock. No need to find your keys, just pull apart. Also, there's a physical backup key, just incase your phone runs out of juice. The lock also features from added security. If an attempt is made to break into the lock, an alarm will sound.

The first physical hardware prototype has been made and coded using an Arduino Mini Pro alongside the BLE Mini from Red Bear Lab (see images below). Second prototype is under development which miniaturises the circuity for a more efficiency by simply using the BLE112 (Ti CC2450 SoC) chip for both micro-controller and Bluetooth 4.0, along with a lower power motor and efficient code.

Developed before the likes of BitLock and Lock8 hit Kickstarter

Lit is a physical, interactive and multi-sensory exhibit that explores the generative relationship between motion, light and audio. Entering into the experience you are presented with an empty, dark space. As you start walking through the installation reacts to your movement in a creative, fun and playful manner.

This project was inspired by exploring reactive architecture through creative technology, venturing away from the dystopian, bleak concrete walls that invade our urban spaces.

On the hardware/technology side, movements are captured via IR sensor technology mounted along a wall. These pick-up movements and are sent to an Arduino which controls the RGB LEDs, while communicating with a sound shield to play a particular sound depending on where you are.

Produced for Digital Shoreditch 2013 - Shoreditch Town Hall, London.

GigaLinc - Kinect controlled Gigapixel imagery

Read about it TechCrunch, Gizmodo, PetaPixel, Cnet, PCWorld Magazine/TechHive, The Engineer, FStoppers

Gigalinc is a creative exhibition that allows participants to physically explore large-scale panoramic images through new technologies. Gigapixel images (1000 times the information captured by a 1 megapixel digital camera) are digitally projected onto a large cinema screen that allows viewers to interactively navigate via physical Kinect based hand-gestures, zooming in and out of areas of particular interest. Surround-sound audio accompaniments added to the multi-sensory experience.

The technology used consisted of several hardware features. The hand tracking utilises Xbox Kinect to input gesture based commands that runs on open source software. Arduino allows the participants to select their image just by tapping one touch-pad on the floor. Arduino was also responsible for allowing the participant to print a section of the image. This is achieved through a large red push button that when pressed, tells the computer to capture the image on screen and print it out instantaneously.

GigaLinc has been shown internationally, including at TEDGlobal 2013 (click for images).

HydroBolt - Technology driven Hydration wrapped in a physical prototype

Keeping hydrated is crucial to our well-being. And whilst it seems simple enough in practice; in reality, people don't drink enough. HydroBolt is a creative, Internet-of-things water bottle that uses technology to analyse how much you drink, and remind you to keep hydrated.

The hardware includes a water flow sensor, a BLE112 Bluetooth SoC (originally developed on an Arduino Mini Pro) to compute and transfer data, and an RGB LED for a glanceable UI. If your Hydrobolt water bottle glows green, it means you are keeping sufficiently hydrated. If it glows red, it means it's time to have a sip.

HydroBolt also comes with an app, designed and coded to help people learn and understand their water-drinking habits, based on the information gathered wirelessly from their water bottle.

eSleeper - A physical 21st century cat basket powered by Arduino

Read about it in Engadget, TUAW and PCWorld/TechHive

eSleeper is a 21st century technology-focused cat basket, designed to be an ideal resting location for any cat. When the feline decides its nap-time, eSleeper’s automated lighting control turns on creative wave of colour inside an eMac, while greeting the cat with the iconic Macintosh start-up chime (keeping the legacy of the eMac). When the cat walks out, eSleeper turns off the lights and tweets to @eSleeper1, displaying various phrases along with how long the cat has occupied eSleeper.

How does it work?

Technology and hardware wise, an Ethernet Arduino is used to control eSleeper. Data is sent to the Arduino from an infra-red beam attached to the inside of the eMac. When the beam breaks, the Arduino turns on the RGB LED, send a digital message to a sound shield to play the Macintosh startup chime and records how long the cat has been inside. When the beam is broken again, the Arduino code turns off the LED and Tweets a random phrase linked to the time spent inside the eSleeper.

Understand the air you breathe

Breathe warning

Read about it in PSFK

View the website here.

Outdoor air pollution is a major environmental health problem affecting everyone in developed and developing countries alike. 3.7 million deaths attributed to the the problem during 2012, making it one of the biggest single environmental health risks.

Breathe is a connected device and smartphone app that enables you to deal with the invisible nature of air pollution. It does this by giving you the tools to understand the quality of the air you breath and to adapt your lifestyle for a healthier way of living.

The hardware provides an automatic signal of the risk of air pollution via an innovative physical user interface, only becoming visible when necessary. The warning signal is only activated when the risk is at an unacceptable level. Breathe incorporates smart technologies such as Bluetooth 4.0, embedded microcontrollers and the latest in air quality sensors. This enables Breathe to analyse harmful gases and identify, process and communicate the air quality around you in real time.

The software allows you to keep an ongoing record of the air you inhale. An app works alongside the hardware, so that you can monitor your daily intake of air pollution and adapt your lifestyle accordingly in order to live a healthier life. The app also helps you identify and avoid air pollution hotspots and to find alternative routes for your journey, with recorded levels of cleaner air. By submitting your air quality readings into a crowdsourced dataset, you will be able to collaborate with others in identifying areas of low/high air pollution that can be easily referenced.

SafeCase - A hardware prototype to prevent your bag from being stolen

A few weeks before I participated in AngelHack 2012, a pub conversation arose regarding a theft of a friend’s bag and the growing problem that such crime presents in society. This lead me to think, 'How can I creatively use technology to prevent the casual theft of valued bags and luggage?' Enter SafeCase.

SafeCase is a physical prototype that constantly monitors movement via a digital accelerometer, connected at an ATMEGA324P (originally Arduino). Owners of the bag wear an RFID wrist band to identify themselves. It's designed so that if no identified user physically moves the bag then an alarm will trigger and LED's will flash, notifying that owner that their bag is in the wrong hands.

First prototype was made the AngelHack Hackathon and Accelerator and received a 'special mention'.

Project part of the Digital Sizzle 6 Hackathon – Group project – Idea, visual look and part coded by me.

Gaia is a mixed creative technology installation that explores people's growing interconnectedness in the urban environment. Using 3D data visualisation and soundscape, Gaia maps London's feelings and movements (through social media data and TFL) to create an experience that looks at how the increase in the amount of information we provide about our day to day lives and emotions can create feedback loops which bring us closer together and help design better urban environments.

From a technical perspective, we took a wide range of data from TFL and put this in to a digital 3D mesh, interconnecting routes and journeys. On top of this, we connect real-time data every 60 seconds on the position of every bus and tube in London.

The prototype also had hardware controls (connected to via Arduino) to speed up/down the visualised data.

Exhibited in the Whitechaple London and Wired 2012.

Visualised using Processing.
