Web Enabled Time/Temp/Humidity and I/O Controller

By statistics I was not referring to parts count. Do you have actual statistics pertaining to the environmental impact of CFL's vs. incandescant bulbs?

The problem isn't how many parts there are. It's how much energy it consumes. In that regard CFL's are way ahead. Again, they're not perfect and they may not be the long-term choice. But for the time being, CFL's give much more light using much less energy, thus ergo much less coal and therefor, do less harm to the planet.

For me personally it wouldn't be that much of an issue as I don't expect to be around long enough to see the worst consequences of what humans are doing. However, I think we all have a responsibility to do whatever we can to reduce our "footprint".

Even considering what you've mentioned so far, it's not a given that CFL's create that much waste. Further, it's certain that using conventional bulbs causes much harm.

have to wonder.

That is a valid point. I have not tested a lot of makes but the ones I have in place have not given me any problems to date. Only time will tell.

Probably not. Companies that make resistors make othert things as well and would still be present even if CFL's were never introduced.

Ford's Model A cost a lot less to build than a Prius. Care to guess which one is more destructive to the environment (when actually operating)? :^)

No, more like the one he posted prior to my tongue-in-cheek "warning".

Point taken. The discussion is over anyway.

"Thus ergo?" One of these days I'll actually proof read before hitting send. :^)

At first people said ethanol was a net energy saver too. But after a similar analysis (like including the manufacturing chain above in total cost) it is now well-agreed that E85 uses more energy to get that gallon to the pump than the gasoline in the next pump. I say a CFL takes significantly more energy to become a CFL than a light bulb takes to become a light bulb, if you add in the cost of making all the parts required. But political forces keep the E85 refineries going regardless of E85 net carbon unfavorability. But politics trumps a deeper analysis of any so-called energy saving device once the device has been sold as a savior. The laws of thermodynamics still apply, those resistors, capacitors, transistors and diodes still take enrgy to make. But denial is a big part of both sides in the green movement. All those parts didn't simply get there by magic, it could easily take more energy to make just one electrolytic capacitor than an incan. bulb considering the chemical electrolyte production, foil production, plastic production, etc.

And war trumps politics (von Clausewitz's dictum notwithstanding). The reason is that E85 is an attractive energy source in the US is that it incrementally reduces dependence on imported oil and can supply energy for transportation -- look at example of Brazil which became 'energy independent' ca 2006. Have we already forgotten the > 10K lives and ~ $Trillion expenditures for the war in Iraq?

Pop quiz:

1) How many resistors and capacitors is a human life worth? 2) Who's doing the denying here?

( I dunno what all the right answers are, but do know that many of us can recognize some of the wrong answers right quick.)

++++++++++++++++++++++++++++++++++++++++++++++

There's another approach (other than E85) to carbon-efficient private transportation. See

Our all-electric 1967 VW beetle is part and parcel of our home automation and distributed DC power system - The car provides ~ 1.6 kWh storage to the home when fully charged and plugged in. And, of course, could be recharged using renewable and(or) non-renewable energy resources.

And yes, it will have one of the CAi Networks WebControl devices that is the subject of this thread.

HTH ... Marc Marc_F_Hult

Time permitting, I'll post a picture of the WebControl (80mm x 85mm x18mm) in its native steel case (100mm x 100mm x 35mm) stacked on a comparably sized Netgear GS-105 hub (95 x 100mm x 25mm) and Comtrol Device-Master AIR (92mm x

87mm x 48mm) which provides WI-FI and RS-xxx in a 100mm x 100mm footprint. This combo allows you to communicate with to a computer, two WebControls and a serial device such as Peter Anderson's data acquisition modules via WI-FI.

(This matches almost exactly the footprint of a Pico-ITX (100mm x 72mm) with the inevitable I/O connectors. These PC's are still too pricey,

but they'll get 'there' eventually. )

... Marc Marc_F_Hult

I can confirm that the WebControl devices being shipped by the Amazon supplier have the same v02.03.03 firmware as what

(the manufacturer) upgrades exist units to. I recently had two boards that I purchased about a year ago upgraded. CAi Networks did them for free for me in appreciation of my testing of various 1-wire devices and Honeywell humidity devices to them, but usually charge $20 + shipping which is more than 1/2 the price of the board without case through the Amazon supplier.

FWIW, I found that the board works OK with the HIH-3600 humidity sensor as well as the HIH-4000 series specified. The bug with the 1-wire appears fixed. Previously, the board would only accommodate Maxim's low-accuracy ( +/- 2C) DS1822 "Econo" device. It now also works with the "High-Precision" ( LOL ! ) DS18B20 ( +/- 0.5C)

Ethanol may not be a net energy saver but it does reduce dependance on middle eastern oil. That, IMO, is a good thing.

I spend a lot of time in Brazil, where my car and my motorcycle run on a mix of gasoline and alcohol (made from cheap sugar cane; not overpriced corn sugar). The cost is less than straight gasoline and milage is not significantly different. The Brazilian government-owned oil comany, Petrobras, claims that production costs -- both financial and environmental -- of ethanol are very close to those for gasoline.

Brazil does not spend one real (pronounced "hey, Al") on Iranian oil. This is also, IMO, a good thing.

That's a bit of a stretch, friend.

Ethanol may be a good idea, but not as the US has pursued it. Sugar cane is a good choice; corn is a lousy choice. Remember the fertilizer comes from middle eastern oil... it takes a lot of effort to show a net benefit on that one.

Algae is looking *very* promising, as a better US approach.

I'm in the middle of corn country (IL) and there is only one independent gas station (Gas City) that actually has E85 pumps available. Additionally the price of the E85 there varies widely and is not much better than regular, (unless regular goes back over $4), the E85 will be $3.50, right now its only a dime cheaper than regular and ouputs less power when burned. If E85 is inconvenient to get in IL corn country then I can only imagine how hard it would be to find an E85 pump in another state with no political skin in the game. Brazil is on the equator and can utilize sugar cane, both those aspects tip the energy-to-produce scale in favor of E85, but we are not allowed to import Brazillian E85 (as much as the Brazillians would like to sell it to us). If E85 was really attractive in US then it wouldn't need govt subsidies, it wouldn't raise the price of food and feed corn, and every company would be jumping on it to make a profit. The fact is it's not an attractive fuel.

We got a lot of fertilizer out of the previous administration as well. :^)

The problem with ethanol is the US sugar industry. More specifically, the complex relationship between agribusiness and the US government makes progress almost impossible.

There is a false premise that many in Congress claim we are supporting "free market" enterprise. In a truly free market we would be importing Brazilian sugar by the boatload. That would bring the cost down at the pump *and* reduce our dependence on middle-eastern oil.

Why not just lower the world barrel price of petroleum instead of trying to avoid the high prices the middle east charges?

Perhap learn the secrets of Outlook Express that you are using. Killfilter the thread. One click and the whining can stop.

Yes, so true, and so responsible for so many blown motherboards and add in cards. I used to participate in a PC user group helpline and I recall a lot of calls from people who thought the machine was off when they hit the switch, yanked the cover, popped in a card or fiddle with a drive and then it woke up and burned up.

When I bought a 10K RPM WD Raptor drive and a dual head video card, the case stayed terribly hot after shutdown, with the sensors showing that the chip temps spiked once the main fans stopped. Fortunately, the low voltage that's always available on an ATX system allowed me to use 5VDC timed fans to keep extracting hot air from the system after it was powered down.

I only ever *popped* a PCI video card that wasn't much good, but developed the rule that when the cover's off, the cord is pulled out of the back. Like Cpl. Dwayne Hicks said in "Aliens" about dropping a nuke from orbit, "It's the only way to be sure!" Before that, I had put some case screws on the shelf that hung over the open PC, listened to some loud rock and roll and the damn screw danced into the machine and killed a tape backup card

As for WOL and other methods of waking the motherboard up, some machines, cards, OS's and BIOS's are definitely better than others. The newer the machine, I've found, the more likely it is to actual work.

Still waiting for my temp and humidity sensors to arrive before I start playing around with my WebControl board. Assembling as much info on CGI and micro-web servers as I can while I wait.

Yes, we seem to be circling around and round ... ;-)

I have an Aviosys IP POWER 9258T and it can do what you want for four outputs. Aviosys also has eight output model(s). The 9258's are available Buy-It-Now for $95, shipping to US included, on eBay. Search for IP POWER

9258* or INTERNET POWER CONTROLLER

The IP POWER 9258 uses mechanical relays rather than SCRs to control power to the AC receptacles, and so can be modified to provide SPST switching of a signal or DC rather than 120VAC. Also, I prefer not to add devices to my system that depend on AC power, so I was pleased to see that it runs internally entirely on 5vdc from a small, easily-bypassed, internal AC-to-5VDC converter.

It is readily programmed though web-based GUI, by sending simple http command strings, or a VB/.net etc programming

Also:

If you are willing to add your own solid state relays and(or) relay drivers + mechanical relays, the " WebControl timer temperature humidity I/O controller " is a TCP/IP device that might suit your needs.

It provides timers and scheduling, NTP time synchronization, email notification, eight TTL outputs, up to eight 1-wire temperature sensors, one Honeywell humidity sensor, three analog in, and 8 TTL inputs.

Sells for $25- $49 (compute-aid.com, eBay, Amazon; sensors not included).

A metal case is also available for $15

NB: As yet, I have no hands-on experience with this device, but have ordered one.

No, he's right. The thread is OT. Sorry.

What is the part number for the digital I/O connector?

Best, Christopher

Sophie, of their sales team, gave me this part number:

TYCO ELECTRONICS - 1658622-3 and said it was available from Newark Electronics. Actually, she just said "Newark" and I assumed the "Electronics" part but I never followed up because I found that an XT era game port/joystick adapter cable also fits and I had a few in my junkbox.
