Hi Howard, What I meant when talking about measuring intensity it is more a feature measuring all the current drawn from the relays (I’m using 12 v dc), introducing a kind of ammeter. Affer some

I don't as a rule distribute that design. And at this point even I wouldn't build an OCS PCB again. I feel the eBay relay boards are a better proposition both in terms of cost and for easy

Thank you Howard, I would say nearly all the features in OCS interest me. LOL I was wondering if my solar panels 150 Watts X 2 and 2 batteries 100AH could supply OCS and all the equipments that's why

I would like to built one version of your solution http://www.stellarjourney.com/index.php?r=site/observatory_control Schema , tuto are disponible ?

I really don't understand the question; but I don't have anything to do with that sourceforge project nor any interest in it.

Yes the OCS PCB Analog inputs A0 to A5 can handle measuring 12V DC directly. The inputs are resistor divided and diode clamped for protection. Since the individual user must decide on a sensor to

Hello to all , I'm target to build a experimental board for sqm detector for fun, And i have start this tuto .. (electronic in order) , and i have discover this new group by onstep . Than it's more

Hi Howard, I'm running the 2.0g and it works fine ! I wired the heater on a relay following you advice and switch it on only in extreme conditions. The rest of the time i switched it off since the box

Thank you. This same configuration file format has worked out well in my other projects and I find it nice for my own use as well.

Snowing like crazy and/or cold as heck so not this time around :)

Sorry you were right, it was windy when i updated and did not see a gateway ip error. It is a great update in config.h and easy to get into, i'm using your "Weather.ino.myObsSetup.txt" Was the

Doubt it, NPT works here. The gateway address, etc. needs to be correct and of course NTP sometimes doesn't answer.

Just checked the updated sketch, it is a lot easier to read and decipher, lots of work on your part, Also thanks for the example code on sensors. Thanks again for the changes Nino

Hi Howard, For feedback I'm testing this version and can't update time. Downgrading to 1.4f and same ip timeserver and time is now ok Koal01

Relay 4 isn't specific to anything. The HEAT_RELAY in this case just happens to be #4, it could be any supported relay. Observatory or box shouldn't really matter the feature is for thermostatic

Howard, I intend to use relay 4 to monitor heating in the box when it's freezing. This relay was designed for heating an observatory but i'm not going to use it in the near future. The relay to be

Fingercrossed ! Hope the weather will change so that you can install it Sqm sensor is absolutely magic ! Good luck

Thanks Howard, that was the other thing I was looking at, switching to a higher amp relays Nino

BTW, this is done and waiting for installation... I'll be up there (at the observatory) this weekend but I doubt I will have the opportunity to install due to poor weather conditions. :)

I don't have a schematic to see what exactly you have wired to what but generally speaking yes a common ground can be run on one wire.
