arduino -- Aquaponic automation development

Started by Rik Kretzinger. Last reply by David Leithauser Mar 27, 2017. 46 Replies

arduino's have a future in aquaponics in my mind.  Not many people talking about their use of arduino's and aquaponics.  Windowfarm groups are much more active with arduino's and control of systems. …Continue

I’ve been accepted to exhibit at @MakerFaire Bay Area on May 17 & 18, 2014

#20475 - internet of farming arduino-based aquaponics

Will be able to show case a number of new leading edge things that I have been developing.

Here are just a few of them:

Design of a "Radial Flow Filter" for the tower unit system ( will be blogging and doing a Youtube video about it shortly"

Venturi DIY design that will replace air pumps on my systems.

Aquaponic Fog Unit that I have just completed and in testing mode now.

Have fully working Tower unit with totally enabled  IoT features that show case the latest developments in this technology as related to aquaponics.

G'day TC,

Like the good programmer I am, I didn't document much of anything. I'm more than happy to answer questions and provide the code though. I might even start a blog to make this stuff available. Let me know what you'd like and I'll see if I can't post relevant details.

Here's my first post: Arduino : How I got sucked in to the vortex

Hay John, Good job.

Just wondering if you have posted anywhere the block diagrams and programing info you used to get your little project there working?

I'm not versed in arduino yet but I've done some picaxe projects (mostly repeat cycle timers) but I did have one with a temperature controlled relay (to keep my auto feeder from feeding if the temp got too cold.)  Anyway, I haven't done any research into how to log/post temperatures yet but I would really like to sometime.  (like I have any time for figuring out new projects......)

awesome job John, I need to get off my butt and work on some of my projects. I don't know if I posted my new fish feeder here. I'll have to take a look later today when I'm off work.

Live Internet Temperature Monitoring

After many, many months of learning, soldering, research and programming, I finally have the temperature of my fish tank being posted live to the web.   I'm using a Arduino-based circuit, DIY built from components, enclosed inside the Linksys WRT54G wireless router that is doing the wireless networking for me.

Here's an early photo.  

And here is where you go to see the temperature chart:

Feel free to change the number at the end to show more or less history.  It represents the last X hours of data, in this case 48 hours = 2 days.

Love it Matt, I bet making the video took about as long as making the FF! I love the combination of slides and video. Slides are far easier to freeze for a closer look and I use them myself. I have been meaning to combine them myself. Well done.

A common misconception with patents is that they offer some sort of protection. They are only as good as YOUR pocket book is deep. Once you patent something it is fully exposed to all comers and totally up to you to defend it so it had better be a million dollar idea and you had better have deep pockets. Just ask Weedeater. Everyone jumped on board and a (no doubt paid off) federal judge took the patent away after the inventor pretty much went broke defending that simple patent.

The best advice I have read, as someone who is always inventing things, is to get it into production and sell the hell out of it before the big boys get wind and steal it because one way or another they will. Make money instead of spending money and have fun. If it is great enough to garner their greed you will have made a bundle already and you can focus on your next great idea as you continue to produce the first idea regardless of the competition. Been there done that.

@Manross, no problem,  I'll check out your relayman.  My next project will be using a relay so I'm interested to see what you've done.

@Frank, that's up to you.  I'd like to see if it you decide to.  I'm not in this for money, for me it's a learning thing.  The wireless part is pretty simple I could get my feeder to be wireless if I wanted to, but a simple digital timer does the trick for me.  If you want it to be battery powered you could follow this hack I found online and use battery's as a power source.  Since I already have electricity going to my system for the pump, I just went the easier route and have the feeder using that power source hooked up to a timer that I set to run 3 times a day.

I have a big problem:

I have designed and tested a much cheaper and simpler, battery operated automatic feeder,

please take no offense, Matt, yours is impressive too

now I am wondering if I should either patent or divulge it,

divulging my idea would impede all patenting

patenting it would allow me to freely share my design with this community for further development, meantime allowing me or us to demand royalties from companies who are undoubtably on the lurch here and everywhere else to make a profit from our ideas, as companies are supposed to do

technically and mechanically my design works as good as flawlessly with whatever size of pellets or even grains

but it can be refined and would stand much stronger if we could add cheapest possible wireless control from a PC

please help

I am not knocking what you did in any way do not take it wrong.
If I came across that way I am sorry.


As microcontroller and computer programmer I love what you made. It is a very inexpensive solution to the bigger problem of feeding the fish. I like the Arduino and the PI both for small setups they have their niches and limitations.  I have created several versions of a controller board myself called "RelayMan" with different configurations and I am currently working on a new version V3.0 to be out this fall. I am also working on an input sensor and relay board to piggy back onto the Arduino and PI.  Check back on it @

For large production I just prefer to use the common items that already manufactured instead of recreating them.

Again I am sorry if I came across as knocking what you did.

Great job and I love the video.
