The feeder that apex uses is from lifegard aquatics.

It's pretty simple to mod it too.

All you need is a small relay to close those 2 contacts to simulate the press of the button. :)

I think the "Everyday Feeder" is just a newer version/packaging of the "Feed Air". They're both model 3581.

I ordered the eheim, but like the look of the intelli-feed. The eheim was under $30 so probably it's a better model to play with in case I toast something!

I toasted my first one because I suck at soldering.
I haven't attempted it again on the 2nd one yet.

Yah, I'm not very good either, especially with the really small stuff. However, I'm getting better with practice, and hope I can pull this off.

It' not that they are small solder point (which they are) it that they are SMD (Surface Mounted) so then tend to unsolder and slide off where they are supposed to be.

I think I melted the push button switch on my first feeder.
I was taught to solder by letting the things being soldered get hot and the put the solder on them.
Obviously SMD has to be done differently.

I think you have to tin the soldering iron and the wires you are adding to the contacts and use flux on the contacts that you are soldering to and then just touch the iron to the area to be soldered, and the solder will transfer off the iron to the area that is fluxed.

I'm with you on this! I just discovered the same thing on a recent project. It turned out quite nicely after I figured it out! Still, I don't feel very confident working on these kinds of things.

Roberto, what specific relay would you recommend on the intelli-feeder?

Use something like this to be safe:

Are you shorting the output of the relay to simulate a button press or applying voltage?

The way it has been done on the Ehiem Auto Feeder is we are applying 12v current to a relay that in turn is closing the connection for the feeder button and rotating the feeder chamber. Simulating a push of the button.

Thanks Steve,
I think I understand, you're using a relay to activate their relay?

I have some relays similar to this and honestly I have no idea how to wire it and program it with the RA.

Any low level tips or links to a tutorial site would be much appreciated.

Damn, I just noticed you said the Eheim feeder...
What about the Intelli-Feed?

Don't know about that one. I know it works with the Eheim.
If you can figure out what to trigger on the Intelli-Feed then it should work.

On that relay from the previous page, could we use 12v versions and the 12v power supply sold on the store to trigger it? Or any 12v device for that matter? Like a 12v water valve for ato reservoir refill or water change bin filling?

Or could the 12v power supply directly drive a 12v solenoid for a water valve?

Depends how many amps the solenoid needs. Most likely not a lot so yes.
