== Members Involved ==
* Codohundo (Travis),
* Standard Toaster (Andrew),

== Project Scope ==
To create an arduino controlled door access system without modifying existing hardware.

== Details ==
Travis & Andrew have engineered the RFID access system out of 2 arduinos, a computer PSU, and electronic latch and a netbook.

== Progress thus far ==
* RFID system is up and installed on the side door of the space

== To Do ==
* Clean up cable runs
* Migrate single database onto a cloud based server, accessable remotely
* re-engineer the entire system for the second door in the back

== Access Control ==

== Project Scope ==

To investigate various methods of growing food for personal use and the possibility of industrial use. We aim to collect data and share with other groups to further the collective knowledge on the subject. As the project progresses, no doubt the scope will change.

Hopefully we will be able to come up with some best practices and schematics so anyone who wants to can make their own system.

==Aquaponics==
Aquaponics is a system who's aim is to emulate the natural cycle of growing food as closely as possible. It uses a combination of hydroponic growing with fish care to create a (almost) closed loop system. Basically, fish food is added to the tank, the fish eat it. The fish waste is used to fertilize the plants. Water is recycled in the loop. In a perfect system, the extra plant mater that isn't used by humans could also be used as fish food. A full explination on the Nitrogen cycle can be found [http://en.wikipedia.org/wiki/Nitrogen_cycle here]

====Lighting====
Natural light is great, but it's not always available. Maybe your house doesn't face south, maybe you live in a cave. Either way, light is how plants do their thing and it also takes a lot of energy. Current lights can easily draw 1000W and cost a [http://www.progressive-growth.com/solarmax.php hundred dollars]. I think we can do better than that. Plants have a very narrow spectrum where they absorb light; so white light isn't really necessarily. With LEDs, the correct spectrum can be used thus creating a more efficient system. If we really want to get fancy, we could liquid cool the LEDs and use that heat to keep the fish at the proper temperature.

[http://en.wikipedia.org/wiki/Grow_light#Luminous_efficiency_of_various_light_sources Luminous efficiency of various light sources]

====Monitoring Progress ====
There are many different things that need to be monitored. Nutrient and pH levels, temperature, flow rates, luminosity and so on. We are going to need some micro controller wizards to whip up some code to keep track of all these data points and log them. We can't figure out our efficiency without numbers. Once we have data we can start comparing it to other systems and tweak as necessary.

For an example as to why monitoring is important, fish and plants need different pH levels, so it must be monitored to keep it in habitable zones for both.

====Tweaks====
There are many different pumps, tanks, filters and systems out there. Should we use a gravity system or multiple pumps? How are we going to deal with heavy metals? What about bacteria? (Good and bad)

All sorts of questions since this is a relativity new science. That's what makes it awesome.

====System Risk Factors====

* Pest infestation
* Microbial infection (pythium, et al)
* Nutrient factors (pH, oxygenation, chemical concentration(s) of ammonia, etc)
* Outside contamination (mishandling, foreign introduction of organic or inorganic material)
* Systemic shock (spikes or troughs due to temperature controls, nutrient issues, stress etc)

Significant research data exists regarding an aquaponics research project in Brooks, Alberta conducted in 2003-2005 (insert citation to CDC Brooks project, Savidov et al 2003-2005). Of particular interest is the team's findings regarding plant yield compared to organic soil-based production and current mainstream hydroponic production in Alberta.

The study found plant yields were "considerably higher than average in organic greenhouse production based on soil, but still 15% - 25% lower than average yields in mainstream greenhouse vegetable production based on hydroponics." (insert citation to CDC Brooks Project, section 3.1.2.1). The research document further examines the potential causes, notably a "lack of experience resulted into a massive loss of plants caused by disease and pest infestation during winter period 2003-2004."

Further research reveals a local strain of Pythium Aphanidermatum was largely responsible for major plant loss, including mention of prevention measures to adopt in the future. As a result, plant yields exceeded the industry average in 2004/2005, over the previously observed performance in 2003/2004 (reference Figure 3 and 4 in CDC Brooks project, page 14 and 15).

==Progress Thus Far==
We have a member that is willing to donate a working system to us. We will also have to decide on what sort of crop we want to grow.

-Update Jan 24

Andy has dropped off his system at the space. There are some parts required before we can fire it up:

- Fish tank filter (AC500)
- Pump (200-300 gallons per hour)
- Pump timer (set to 5-15 minute intervals, 2-3 times per day)
- Heater (250 watt, set to 72F [22.2 C])
- Hydroton
- SeaChem Prime
- Rockwool
- Seedling grow tray

==To Do==
First things first, we need to get the system up and running. Once it's up, we can start tinkering and monitoring it's progress. There are several areas that we can look into.
