What kind of impact does growing your own food have on the world’s resources? Jump aboard for a little thought exercise on this week’s Time for the Prize challenge to brainstorm urban gardening and living off the land.
We figure for any kind of meaningful impact there would need to be wide-spread adoption of people growing at least some of their own food locally. This means making the process fun and easy, a challenge well suited for 2015 Hackaday Prize entries. Write down your ideas as a project on Hackaday.io, tag it 2015HackadayPrize and you could win this week’s prizes which are listed below.
Space, Information, and Automation
To get rolling, we started thinking about three things that are needed to convince people to grow their own food or live off the land.
First up, you need space to grow. This has been the subject of a number of urban farming hacks like the one seen here which uses downspouts as a vertical garden apparatus. Openings are cut into the front of the tubes, which are each hanging from a PVC rack. Each opening hosts a plant, holding them where they have access to sunlight, while taking up very little space on a sunny balcony or sidewalk.
The concept also includes a bit of automation. It’s a hydroponic garden and simple sensors and controllers handle the water circulation while providing feedback for the gardener through a smartphone app. We think the technology of the system is one way to attract people who would otherwise not take up seed and trowel.
For those new to taking care of plants the other thing to consider is information. Not only does the sensor network need to monitor the system, but something valuable needs to be done with the data. Perhaps someone has an idea for city-wide aggregate data which will look at successes from one urban garden and make suggestions to another?
This is your time to shine. Get those ideas flowing and post them as your entry for the Hackaday Prize. Even if you don’t see the build through the idea can still help someone else make the leap to greatness in their own brainstorming.
This Week’s Prizes

We’ll be picking three of the best ideas based on their potential to help alleviate a wide-ranging problem, the innovation shown by the concept, and its feasibility. First place will receive an RGB Shades Kit. Second place will receive a GoodFET42 JTAG programmer and debugger. Third place will receive a Hackaday CRT Android tee.

The way things work right now, you go to the store and pick out a card. You write a personal message inside, lick, stamp, and send it through the mail. The thing is, this card is probably already in a store down the street from your mother. What if you could digitize your handwritten message and have it printed on the card and delivered from a local repository? Take it a step further, assuming that these cards are bulk-printed in one central location and distributed widely, does it save any resources to decentralize the production of the cards and make production local so that the finished goods are not being transported more than 500 miles? And for those skeptics saying that you can’t add a check or cash to the card when done this way… yes you can!
Standard practice is that the part be ordered from a parts supplier (either by you or by a serviceman). These suppliers keep a stock of common parts which are well documented in a huge library of service manuals for the myriad of home appliances out there. But when you get right down to it, it’s just a little plastic bauble. Let’s assume all of these are made in a single factory in huge production runs that supply both the manufacturer and the legacy parts houses. What if instead of this you could have these parts 3D printed by a business within 500 miles of where they are needed. There are industrial-grade 3D printing techniques that produce parts strong enough to act as a replacement. Where do you come down on resource saving between the two methods?
