willosof Posted July 31, 2008 Share Posted July 31, 2008 Hi all! I'm back, now with the 1.6 out and everything, i've been reading the driverworks-sdk, and it's fan friggin tastic I hope to get some lua working by the end of this day, and i've ordered some new parts for my system now.I allready have the http://www.mikroe.com/en/tools/picplc16b/ development board with 16 relays and 16 sensors, so, i'm making a driver for controlling that via ethernet $159 for the board Cheap and loveable.I'm also working on getting my Dallas 1-wire system up and running with control4. I've bought 14 temperature sensors, and i'm hoping to be able to set a variable in director for every temperature in every room of my house. (in time i will add humidity and a pressure sensor as well), so i can run things like..If livingroomtemp > 20 then blah Total cost for "control board" and all 14 sensors on norways most expencive electronics shop: $200 (..cheap!!)More coming!

mcdader Posted July 31, 2008 Share Posted July 31, 2008 sounds good, I am interested in hearing how this works out. Link to comment Share on other sites More sharing options...
willosof Posted August 5, 2008 Author Share Posted August 5, 2008 Woha! Now 10 out of 13 are up runining. My DriverWorks driver arent done yet, but atleast i've gotten it up running with munin http://casa.exploit.no/munin/skogmo.int/public.skogmo.int-housetemp.html Link to comment Share on other sites More sharing options...
mcdader Posted August 5, 2008 Share Posted August 5, 2008 Looking good, I can't wait to see how it works with control4. ThanksRalph Link to comment Share on other sites More sharing options...
jbs Posted August 5, 2008 Share Posted August 5, 2008 If livingroomtemp > 20 then blah Willosof, looking at your graphic your house must be freezing all the time! 20 degrees, how do you keep the pipes from bursting?And yes, everyone, I am joking. (http://en.wikipedia.org/wiki/Celsius)In seriousness, though, at what temperature do folks strive to keep a server room? Looks like Willosof's is a cool 70.6 degrees. Mine is not separately air conditioned, I just have fans circulating air through the rack and out through the ceiling, but I'd love to know what constitutes a "safe" temperature for people's electronic equipment.

thecodeman Posted August 5, 2008 Share Posted August 5, 2008 Depends on what you have in there Can't go too low or start having to worry about humidity and all, and the electric bill! But generally it depends on how much heat your equipment is putting out. Link to comment Share on other sites More sharing options...
mcdader Posted August 5, 2008 Share Posted August 5, 2008 I like to keep my home at a nice 68F , this includes my computer room and server room. Link to comment Share on other sites More sharing options...
thecodeman Posted August 5, 2008 Share Posted August 5, 2008 Wow I must be cold natured. I keep my house around 76-78*F... lol Link to comment Share on other sites More sharing options...
jbs Posted August 5, 2008 Share Posted August 5, 2008 I like to keep my home at a nice 68F , this includes my computer room and server room.I hope you live someplace that's already quite cool, or in a pretty compact place! I can't imagine what it would cost to cool our house to 68 (the avg summer temperature here is in the 80s, but we get plenty of them in the 90's). We keep our thermostats generally at ~76. My server closet without the fans running would quickly get to the high 80s or maybe higher (I try not to find out). With the intake and exhaust fans I've installed it keeps it usually right at 80, but occasionally approaches 82.When I was shopping for exhaust fans for racks I found that many of the thermostatically controlled ones would only kick on at 88 so I'm guessing that 80~82 is well below the electronics danger zone. And I can cool it for pennies a day in electricity versus quite a bit more if I was using an air conditioner in there. Link to comment Share on other sites More sharing options...
mcdader Posted August 6, 2008 Share Posted August 6, 2008 about $200 a month electric. I am in pleasantly warm arizona. After working outside all day it is work it. Link to comment Share on other sites More sharing options...
danlevine Posted August 6, 2008 Share Posted August 6, 2008 willosof this is sick... love the rrd graph. is that embedded into the device or do you have a separate apache server running that? Link to comment Share on other sites More sharing options...
willosof Posted August 6, 2008 Author Share Posted August 6, 2008 Right now it's one of my 1U rack-servers hooked up to the 1-wire network with a serial port(rs232). Reading values and parsing stuff with perl and graphing done with munin. I was thinking of making a serial driver for the sensors for C4, but. I'm not sure anymore I don't think I want to waste my precious CPU power on my lousy C4 HTC (Hey! Donations are allowed. I'm on a low budget ), which runs my house - on all the things i want to do with the temperature measurements Yeah Everything it takes.. The black ones are the digital temperature sensors. So.. Yep! This is the house: (FYI! Link to comment Share on other sites More sharing options...

This temperature range provides a safe buffer for equipment to operate in the event of air conditioning or HVAC equipment failure while making it easier to maintain a safe relative humidity level.""In a data center or computer room, maintaining ambient relative humidity levels between 45% and 55% is recommended for optimal performance and reliability. When relative humidity levels are too high, water condensation can occur which results in hardware corrosion and early system and component failure. If the relative humidity is too low, computer equipment becomes susceptible to electrostatic discharge (ESD) which can cause damage to sensitive components"http://www.avtech.com/About/Articles/RA7E/NA/All/-/DD-NN-AN-TN/Recommended_Computer_Room_Temperature_Humidity.htm Link to comment Share on other sites More sharing options...
