    Rain Sensor Status

    Definitely AC - the last page of that link shows the max output including a master solenoid as AC. Also this page shows troubleshooting the valves using AC on DMM http://www.hunterindustries.com/support/valves-testing-voltage-controller-and-solenoid Cool, just a switch, makes that change quite...

    Rain Sensor Status

    LOL, no but I was responsible for the direction this took, so I indeed am responsible for the poor outcome. My apologies. I did have fun, a sore neck from soldering all those connections - I did it point to point with a poorly thought out board arrangement and a blown cap! As you said above...

    Rain Sensor Status

    Correct, Rain-Clik. Good points made above and in subsequent paragraphs. I didn't realize that when I thought of this circuit and honestly at only a scant 8mA I thought there wouldn't be much conflict. With the switch installed and wet, the AC signal is 3.48V (was 3.39V). As for internals, I...

    Rain Sensor Status

    Both good questions... and as the commercial always says: the world may never know :)

    Rain Sensor Status

    LOL C3 exploded when I connected it to the actual circuit! I am glad it was in a case when it happened! Confused as to why that happened - it was rated at 10V and the simulation showed about 2.7v across it. Was it because I used a polarized capacitor? Here's a picture of the aftermath for...

    Rain Sensor Status

    LOL, now you say it doesn't have to be so complicated! I just finished all those connections last night!! :D:D Steve did point this out, but I was concerned with too much variability in the supply voltage. It turns out that the supply is stable despite the solenoids being actuated. I had the...

    Designing a Time Delayed Relay

    You sir, are ACES!!! Truly, you have been such a great source of information and a patient teacher. I treasure you and your help, thank you, thank you, Thank You! LOL :D:) It's a bit cleaner, I am attempting to print it out and have a gander at it.

    Oh, forgot, before I send it off, I will clean up the names/values layers a bit.

    Designing a Time Delayed Relay

    Really?! Well thank you, but I hardly think you can be surprised by the outcome! Novice with expert guidance equals success :D Can you assist me with one question on the Rain Sensor build, I had an unexpected outcome despite breadboarding. Perhaps you can aide me in troubleshooting? Thanks...

    Designing a Time Delayed Relay

    I moved the Allegro slightly down and C10 down and to the left. There is still 0.07" (70 thou) of space between the pads of the chip and the ground plane. Unless you can think of anything else I will submit this to the board house for their check. Thanks!

    Designing a Time Delayed Relay

    Cool! Its currently 16 thou. I have watched each layer after changes and added vias where necessary. The isolation is set at 32 thou, that is what is giving a lot of space between traces and ground plane. I can change it, what would you recommend? Edit: If I change the isolation to 12 thou I...

    Designing a Time Delayed Relay

    Excellent!! Yes, that would be a really easy method of keeping everything aligned while judging space. Sticky that somewhere for others ;-) The trace would get pretty skinny, is that ok? The layout looks roomy, but in truth we are dealing in small numbers!

    Designing a Time Delayed Relay

    Thanks again for the suggestions, I couldn't get it the other day, there were so many things connected, I figured it was good enough. The trace from pin 8 is a bit close to the edge, but at least its still within. It's 12 thou so its smaller than the other traces, ok for signal? I am thinking...

    Designing a Time Delayed Relay

    Its funny you should mention that! I looked at doing that yesterday because its sitting outside of the ground plane, but I couldn't work it out, i thought the clearances were too tight. Awesome suggestions, thanks!

    Rain Sensor Status

    I finished assembling the circuit, checked all my connections, but did not get the anticipated outcome.... I used a 5v supply to test the circuit starting at the v. regulator, negative on common pin 2 and positive 5vdc at pin 3 out. No external AC signal was available so I left that open. The...

    Designing a Time Delayed Relay

    Just messing with you ;-) I will check out your suggestions later on tonight, I am currently soldering up the Rain Sensor project! Thanks

    Designing a Time Delayed Relay

    Lazy? Maybe, however, I am typically very persistent ;-) The software is stating drill distance, I haven't a clue as to what its referring to...

    Designing a Time Delayed Relay

    I thought that it did improve longevity of the traces, something about current not "hitting" a right angle and scouring away at the trace. I will do it, I think the software has a miter function. I did that as I constructed the BOM. As I entered each piece I checked the given size and pin out...

    Tell me your advice for my PCB Layout please

    I think it looks great! Nice job in packing and placement of parts. I am a novice so take my critique with a grain of salt - not knowing what the relays are switching (I assume from their size that its a low load) you may want to increase the isolation value between the relay ground planes and...
