The Cybernetic Earth And Hardware Hacking With Sensors  

Here’s why I want you to get excited about hardware hacking: imagine the Earth was a patient in a hospital. This patient would be hooked up to sensors monitoring its heart rate, blood oxygen levels, and brain activity, with all the data displayed in real-time on a screen. Alarms would go off if anything went wrong, enabling doctors to intervene immediately.

If we can care for a human patient with such precision, why can’t we do the same for our planet?

Why the Planet Needs You

1. We Need More Data

There’s a chronic lack of data on our environmental footprint. How much water do we use? What’s the air quality on our streets? How much trash do we generate? Even cities and states often struggle to collect and share this information.

Without comprehensive data, we can’t fully utilize powerful tools like disclosure, leaderboards, social comparison, feedback loops, and progress bars to motivate change. As they say, “If you can’t measure it, it probably doesn’t exist.” Hardware hacking can help fill this gap.

2. We Need Granular Data

Broad averages don’t cut it. We need data at the level of individual households, businesses, and streets. Without granular details, we can’t compete with our own scores, compare our performance to neighbors, or identify hot spots like heat sinks or pollution pockets in cities.

Emerging startups like WaterSmart and Air Quality Egg are beginning to gather more localized data, but we need more grassroots efforts to map out these critical details.

3. We Need Real-Time Feedback

To inspire action, data must flow in real-time. Just like a Fitbit motivates you by tracking your steps throughout the day, real-time environmental feedback keeps motivation high.

A Harvard study on Opower’s electricity usage charts revealed that energy efficiency spiked when residents received their reports, but those efforts quickly dropped off. This underscores the need for continuous feedback loops to sustain change.

4. We Need the Data in Usable Formats

Much of our environmental data is trapped in PDFs and spreadsheets—formats that can’t be easily integrated into apps or platforms. By designing sensors that feed into databases like SQL or MongoDB, we can create tools and applications that make this data actionable.

5. We Need It to Be Affordable

Sensors and hardware can be costly, which often limits their deployment. But DIY hardware hacking offers an affordable alternative. When I needed a Wi-Fi-enabled trash scale, I found companies selling them for $2,500. With some ingenuity and help, I built one for under $100.

Hardware Hacking Enables Change

Pairing hardware projects with gamification techniques can supercharge behavior change. My video course, “Save the World with Gamification,” teaches 15 gamification strategies that integrate seamlessly with real-world data from sensors.

For example, you could:

1. Install water gauge sensors on taps and use an LED to alert users when they exceed a daily water limit.
2. Build an Ambient Orb that changes color based on electricity usage.
3. Create a trash can that measures its weight and charts progress toward zero waste.
4. Develop thermal heat maps of cities to identify hot zones and advocate for cooling interventions like green walls.

The possibilities are endless, and each project can be a step toward real, measurable change.

Getting Started with Hardware Hacking

1. Identify an environmental issue you care about.
2. Determine what data you need to measure it.
3. Research sensors on platforms like SparkFun or Amazon.
4. Explore tutorials on YouTube, Instructables, or Hackster.io.
5. Purchase an Arduino or similar microcontroller to get started.
6. Assemble your components, solder wires, and test your creation.
7. Build a feedback loop for your data.
8. Store your data in a database for easier analysis.
9. Layer in gamification features to motivate change.

My First Hardware Hacking Project

When I set out to create a game for zero-waste living, I realized I needed real-world data at the core of the design. That led me to build a “smart” trash can that weighed itself and sent the data to an app via Wi-Fi.

I was initially intimidated, but after some Googling and help from friends, I found a tutorial and pieced it together with the following:

• Arduino
• Four load sensors
• A combinator, amplifier, and Wi-Fi shield
• Solar panel for power
• Bamboo board for mounting

With these basic components, I turned an idea into a functioning prototype that became the heart of my zero-waste campaign.

A Cybernetic Future

Imagine a world where the Earth is monitored like a hospital patient, with sensors tracking every critical metric in real-time. This data would feed into a “living, breathing dashboard for the planet,” as Google Earth’s Rebecca Moore envisions.

I dream of a future where technology, humanity, and nature work together in ecological harmony. By starting with small DIY projects, we can lay the groundwork for a smarter, more sustainable planet.

It’s time to start hacking.
