Here is how I did my slide switch so I could move from two different power sources. It worked the way I thought it would, but until I actually connect things up I am never sure. The basic concept is that all positive (RED) wires come off one side of the switch and the negative (BLACK) wires come off the other side. It does not matter which is which, you just need to be consistent so you can duplicate the results on future projects. Each one of the power sources are at the ends of the slide switch. Again it does not matter how you connect it up, but each source needs to be opposite of each other. Configured this way the center prongs will be passed power depending on which end you have the slide positioned.
Slide Switch – making it work for my need April 7, 2013Posted by rik94566 in agponics.com, aquaponic automation, aquaponics, aquaponics electronics, arduino, DIY aquaponics, Uncategorized.

First question is what is a “SLIDE SWITCH”? Well they are very common. Never thought I would need to know how they worked and how I was going to connected them up. As it turns out I have two projects now that require them. So now is the time to work out how to connect them up.
Here is what one looks like. They are found in many electronic devices.
Yet again in electronics you need to know what it is that you want. There is not just on size fits all when it comes to “SLIDE SWITCHES”. I thought this was going to be easy to get connected up.
Here are just a few of the options I had and decisions I had to make on such a small part.
SPDT – Single pole double throw
DPDT – Double pole double throw
SPST – Single pole single throw
Heavy Duty Slide Switch
DPDT Right-Angle PCB Mount
These are just the options at Radio Shack. Do an internet search and the options are endless (seems like).
To solve my problem I made a trip to Radio Shack and made a purchase to get started.
Once I got them home I had to deal with picking between the option of 2-3-4-6 prongs to work with. To solve this issue pulled out my multimeter and tested my options.
The end result I was after is to be able to switch between external power and arduino power (parasite power) for my sensors. The reason for this is some times I want to run external power, but when I am only testing a few sensors I just want to keep things simple and run off arduino power.
The end result was use a DPDT Slide Switch. This required to use the 6 prong switch.

I was reading through my blog feeds and ran on to this item:
HERE IS THE LINK IF INTRESTED:
I have been interested in establishing standards in all the things that I work on because when I start to scale I will need to have documented processes in place that will allow for building SOP (Standard Operation Procedures). An aquaponics business is no different than other well established industries. So now I have one for all my wire connections that are well documented and well established.
RELAY ORDER CAME – March 2, 2013Posted by rik94566 in agponics.com, aquaponic automation, aquaponics, arduino, sensor, Yourduino.

I reviewed my options on larger relay sets and picked the following ones from Yourduino site.
I went with the Opto-Isolated units as they are much safer when using around water and 120 volt systems. My plan is to build a 12 outlet controller portable unit. Don’t know what it will look as yet because the plan is still in mind I know I will have 8 relays configured to be in the closed mode and the other 4 relays will be in the open mode. This I think will give me the most flexibility with all the items I want to control with this unit.
Asparagus – new crop for this year February 23, 2013Posted by rik94566 in agponics.com, aquaponics, asparagus, DIY aquaponics, Yield Results.

I wanted to try a new crop this year. So I did some research for my area and picked a crop that I had some interest in for quite some time, but had no idea how to grow it. Then to try and grow it using aquaponic method is really out there as a concept. Doing a internet search there is very little to no information on the subject of growing asparagus in an aquaponics system.
So here we go with my first attempt at growing Asparagus in my 100 gallon unit.
I placed an order for my starts in early October so I was assured of getting my plant material by Mid-January. I had no idea of what the weather would be like in Mid-January, but I took my changes on getting the starts. There was a chance that if I ordered to close to the actual shipping time from the company I would not get the plant starts I needed to launch this new growing adventure, as the company does run out of asparagus early in the season.
The next big issue was how should I plant them in my grow beds. I learned that asparagus is planted 12 to 15 inches below ground in late January to early spring, so my timing was good but needed to empty my aquatubes to be enough depth for the starts. Once the grow tubes were empty I covered the bottom of the grow bed with enough gravel to make sure the starts would not be sitting in standing water when the grow beds drain after each watering cycle. This is because to fully drain out of my grow beds there is always some water that sits at the bottom of the grow beds and will drain out over longer period of time.
Once I had all my starts place in the grow beds I covered them in gravel up to the crowns. Then I put a very thin layer of gravel over the crowns.
In my research I found that when planting asparagus – you place the starts and cover them lightly and once they start and throw shoots you cover them a little bit, just enough to support the sprouts until they reach ground level or in my case the top of my gravel beds.
Next was to give them some water so I could bring the starts out of dormancy. I did not want to over water them and cause disease problems so I watered them once ever other day. Temperatures had been down in the low 30′s with day time temps only getting up high 40′s.
After one week I had my first shoots.
PRINTED — 3D part now printed and ready to use February 21, 2013Posted by rik94566 in aquaponics, arduino, Rj45 connector, Sketch-UP.

Well it has been a journey to print my first 3D item. Here it is.
Here is a view of printed socket with parts that will actually be use in the final product and compared to my proto-type.
Here is the actual cost break-down on the printing:
Now for the killer: SHIPPING —-
The item was shipped from Oakland, CA to where I live only about 35 miles and went out UPS. The thing weighs less than an oz or two!
Total came to $20.45. At this rate the cost of a 3D printer is well within reach in the near future. With all the things I want to create and print I can keep a 3D printer busy most of every day.
SCALE-UP TIME — this solves the to small to print RJ-45 socket problem February 12, 2013Posted by rik94566 in aquaponic automation, aquaponics, Rj45 connector, Sketch-UP.

Now I have a single unit RJ-45 socket cleaned up and water tight. So now I needed to deal with the issue of my single model being to small to print. Since I actually needed a 4 segment for my finished assembly that fits on my arduino case. Here is the finished single model.
I started with the single unit and added one additional unit at a time. I got all the alinements correct on each level before moving on to the next addition of another unit to the scale up. Here is the total scale up and ready for printing. The finished model is 25mm X 68mm.
LAST CLEAN-UP ITEM — now the model is clean and water tight February 7, 2013Posted by rik94566 in Uncategorized.

I was not happy with the edges on the curved part of my model, so more research on how to clean the curve up>
As it turns out Sketch-Up has a “SMOOTHING” feature to make this task a snap. Cool tool, just needed to figure out how it worked.

With a little research on my end I found the Sketch-Up plug-in that had very good help features. The product is CADspan.
You can down load it here if you have a need for this type of product: http://www.cadspan.com/tools
Here is a YouTube to help you visualize what is possible with this technology:
