Well, I guess I spoke too soon. I had to power-cycle my device again last Friday (April 12th). smiley-sad

I don't know what's going on in my garage, but it must be pretty bad. I think I mentioned it before, but I've had to power cycle some of my other electronic devices in the past. For instance, I have a network-enabled sprinkler system controller that I bought from rayshobby.net that I was always power-cycling, but after I put it on a UPS, I only have to power-cycle it only every couple of months. And come to think of it I have to power cycle my router and my network switches once in a while too.

This is really making me think that there's nothing really wrong with my device and that it's purely the power in my garage. Is there anything I can do to correct the power in my garage/house?

Still so far so good...it's been 8 weeks that I've had my device connected to a UPS and not a single problem.
(See my reply #53)

Yikes!

So  there's nothing I can do/change on my device (i.e. add more caps or something) to make it more 'stable'? (Easy/cheap route?)

What kinds of things can I do to improve my home/garage power? (Difficult/dangerous/expensive route?)

Wait - so the router wasn't even plugged in? That's crazy!

(Thanks for the reply)

Hello all,

I have a possible interesting update on my project. On February 3rd, I put my device onto UPS power instead of just a cheap surge protector. It's an APC Back-UPS 650. And I haven't had one problem with my device since.

Maybe it's too soon as it's only been a month, but it sure is looking good so far...

(What does this suggest? What could I add as far as more active/passive components to my device so that it does not have to be on a UPS, if this is in fact solves my problem?)

Thanks. smiley

My device (as I call it...which consists of the circuit on the proto board and the ethernet shield) allows me to open/close my garage door remotely via my Android phone.

The top pair (heavier gauge of red/black) of wires go to a reed/magnetic switch. (This and a magnet on the actual garage door, allow me to see the status of the garage door via my app - open/closed).

The bottom pair (lighter gauge of red/black) of wires run to my automatic garage door opener (specifically, they're connected to the same 2 terminals that the 'hard button' is connected to. You know, the button that you usually have near the door that leads from your house into your garage).

So the ethernet shield on the right obviously allows me to connect to the Arduino remotely (whether via my internal network or the internet), and open/close the door (and to check the status of the door).

The 'blue cube' in the upper right corner - it does happen to be a relay, yes. The relay is electrically connected to that 2nd blue screw connector where the thinner pair of red/black wires are leading out of. Which in turn, is connected to the automatic garage door opener that I just mentioned. So this does the actual opening/closing of the garage door.

I'm not 100% sure of where you're going here, but remember this strange thing:
It seems that I can have my device plugged into any power outlet in the garage and I'll have the same problem (eventually) (The reason I started this thread). However, as I mentioned in an earlier post, I learned that if I run an extension cord from the garage into a bedroom in my house and plug my device's power into that, I never seem to have the problem (at least after several weeks of testing).

Actually my Arduino is my proto board...if you look at the top photo of my very first, original posting (on page 1) of this thread, you'll see that the proto board is basically my Arduino. The professional board to the right is just an Ethernet Shield which is receiving power from the 'Arduino/proto board'.
So with that, are you saying that I should power the Ethernet Shield separately somehow?

Whoa that was way over my head...could you maybe dumb that down a bit for me? smiley-wink

Well after a few weeks of successfully running, I had the same problem again. smiley-sad It did seem to run longer than usual without messing up, but I did power cycle again, and let it run again, just to see if it was a fluke, and it happened again. Then again. So I don't know if it lasted longer because of the newly added cap and/or just because it's been colder, but that didn't fix it.

Trying to collect my thoughts and figure out what to do next...any more suggestions welcome. smiley

@wolfgang:
I followed your advice on using another capacitor - I bought one of these 1.0µF capacitors from digikey, and soldered it in near my other 2 caps and voltage regulator:

Back side, soldered in, before clipping leads:



And front:


(So I'm not sure if this is the right place to have put the new capacitor, but that's where it is)



When done, I put my device back in the garage, and hooked everything up and plugged it into the power outlet in the garage that I originally had it in, and so far no problems. But it's also colder now (still don't know if the weather matters), and it's only been about a week or week and a half at most, so I don't know if my problem has been resolved or not, but I sure hope so! I will definitely keep you all updated.



@Build_it_Bob:
Thank you for the suggestions...I think someone else suggested I do the same, but haven't yet as it doesn't seem like it would cause the problem I'm having (and on my board, the screws are nowhere near any electrical connections)...especially since my problem has been seeming to be a power problem. But I will definitely keep your suggestion in mind for future reference and implementation.

Thank you all so far.

Shown below is my device, installed in my permanent location, and circled in red. Also notice the 3 fluorescent lights, which I believe is on the same circuit.


This image shows where the Ethernet cable crosses the electrical cable for the lights. I've always understood that as long as they cross like this (are perpendicular), it's ok...you just never want to have them running in parallel.



I currently have it connected to an extension cord (orange, hanging down) which as I mentioned in a previous post, goes to inside my house, and it works fine when connected like this. However, when I have it plugged into the black power strip (where I want it to be plugged in long-term/permanently), I have the problem previously mentioned.

Anyway, in answer to your question, dswan75, the ethernet cable does run within a couple of feet of the middle lights, but I don't know if it's an 'air'/'airwave' problem...it seems to be inside the actual electrical lines themselves that's going into the power of my device wouldn't it? Because again, that ethernet cable never moves through my testing.

@Hugepedlar - I don't know if I have a battery that could power it for very long...a 9V wouldn't last very long, would it?

I don't know how to check for memory leaks yet. I still tend to think it's a hardware issue, but I will look into it. Yeah, I've been thinking of hooking it up to the Arduino serial monitor, but have been putting it off as I will have to modify the circuit in order to be able to do that I think.

I'll see if I can find something like that to put the project in.

Well when I had it in my room, it did work for weeks if I remember right. And when I have the device in the garage, and the power running to inside the house (in my room specifically), it worked for weeks also.

Thanks everyone so far...maybe the pictures will reveal something I'm missing...

So was the transformer that you are referring to powering your Arduino? How do you know it wasn't filtered? How did you filter it? Or did you buy a new known filtered one? If so, which one specifically?

Thanks

I don't think so - I'm using the 'Ethernet' and 'SPI' libraries.
14  Using Arduino / Networking, Protocols, and Devices / Re: Sudden unreliability with my network-enabled Arduino project on: November 17, 2012, 02:43:46 pm
Could fluorescent lighting (I have 3 separate fluorescent lights) cause the problem?

Actually the board is vertical in the garage. But I tried it vertical in my room, and never had the problem, and tried it horizontal in the garage, and still had the problem. I did actually think of that one too.

Thanks for the idea!
