Sprinkler System Infinite Resistance

Well last night, my lovely wife remembered an event from last year. “Remember when your Mom and I were gardening and we cut a wire, but we thought it was a telephone wire? Could that be the sprinkler wire?” A lead! Although, if it were a telephone were that should have been noticed by some angry resident. Also there is no sense why it would be alone.

Went out this morning to take a look at this telephone wire and sure enough it’s the sprinkler wire. Why they decided to lay it going around the entire back yard, I don’t know but now I need to connect them with some weather proof connectors.

That difficult fix was made a lot easier by identifying the problem!

Now to figure out why 2 zones don’t kick on manually.

Water and Electricty

I had briefly alluded to this in the previous post, but it’s really the main reason I’ve had so much attention on my irrigation system lately:  I’ve got no electricity in my water!

Well, not exactly…but electricity is not flowing which means water isn’t flowing to my very thirsty lawn.

It started earlier in the season when I was trying to start up the system and manually test zones.  The weather decided it was going to rain until about mid June.  It also seemed to rain every weekend.  This meant the rain sensor was always activated when I was home and the controller would not fire any zone, even if triggered manually.  This was frustrating.  (Looking back it may not have worked due to all of the problems I am having now. Read further to understand.)

The logical step was to bypass the sensor.  At the time it didn’t appear to do anything.  Frustration increased.  I had had it up to ~points to chest~ here.  If the bypass wasn’t going to work, I’d bypass it the old fashioned way by unplugging the rain sensor.

This turned out to be possibly a bad idea.  After unplugging the rain sensor it became apparent that the controller would no longer turn on.  Further investigation revealed that the wiring job inside the controller was a pretty terrible hack job.  At this point I assumed I fried the controller and didn’t want to bother to troubleshoot it as I wanted a different controller anyway.  (Upon further thought, I may have fried the outlet or something.  Power strips don’t seem to work in the outlet, but the refrigerator we have does.  I’m nervous that the ground isn’t working properly.  Some one please illuminate me on this one.)

I went out and purchased an EtherRain with the intention of integrating it into a home automation system.  For this to work I had to convert my current redundant router into a client bridge that would allow the Irrigation Controller to exist on the home network.  This in itself is another post; for now just know that it went smooth and you need to run the Ether Admin application on a 32 bit machine.

With the zones hooked up to the EtherRain, I decided to give it a go.  I found that 2 zones were able to be activated from the controller and 5 appeared dead.

Group 1 didn’t work, Group 2 had 2 of 3 working and Group 3 didn’t respond at all.

Elizabeth’s dad was over and showed me how to activate the zones manually.  This would prove invaluable in my troubleshooting experience.  I was able to narrow down which zones were not working due to bad solenoids/wiring and which zones likely had a bad jar valve or diaphragm.

I now believe that group 2 has a bad solenoid and group 3 has a bad common wire connection.  Group 1 for some reason started working after I fixed the sprinkler heads.  This made no sense, but I’ll take what I can get.  In addition to not responding to electricity group 3 has a zone that has ceased to respond to manual activation.  I actually shut of the water line to the entire sprinkler system and took apart the jar valve for this misbehaving zone.  I could see no issue.  I believe that there is something plugging the pipe, bad diaphragm, bad solenoid or a leak in the pipe underground some where.  I have no idea how to cheaply test these hypothesis.

Hopefully the heat abates and I can get the multimeter on the wires this weekend and try to figure out if there is indeed a break in the wire to group 3.  I don’t know how much I can figure out as the zones didn’t respond to a DIY zone activator.  (This removes the controller from the equation and gives guaranteed voltage to the circuit.)

It’s at this point that I am debating hiring a professional to finish the job.  If it turns out that there is a short or a cut in the wire somewhere, I certainly do not want to have to lay the new wire.  A number of the heads need to be readjusted (dugout and repositioned) and due to foliage growth new sprinkler heads should be added to the system and some nozzle changes are needed.  (If you read the previous post you know that most likely means changing the sprinkler head itself due to outdated parts.)  It’s starting to look like a serious task that is a bit beyond my desired involvement.

If anyone has some basic wiring skills, I could certainly use the help this weekend.  I’m going to give it one more go before I break down call a professional.  We are currently manually activating each zone to water the lawn and that needs to come to an end.

That is about it for now.  Ideally the next set of posts will be related to MOSIM the work in progress name I’ve give the JS/HTML5 project that has become my coding playground.

The State of Gaming

The time is upon us again. E3 is back and has returned in the form of it’s former glory. Gone is the small scale industry expo. Back is the grandiose caffeine infused, neon light flashing, booth babe ogling and rock star atmosphere. It’s a very exciting time of year for gamers.

Fanbois the world round are brushing off their insults and lolcatz clipart. The biased insults have already started to fly as coverage begins. It’s like hunting season. Except the deer have guns and are shooting each other.

The comments I’ve read have got me to thinking about the state of gaming and where it could go from here.

—Break—

So I started writing this post a few days ago and I’ve picked it back up.

I would have to say that someone behind the curtain agrees with my thinking.  That is, that we have reached the limitation of our technology.  We can improve graphics, but we are already capable of entering the “uncanny valley”.  The “uncanny valley” is the point where a human representation on screen is so close to life like, while still missing “something”, that we actually start to dislike the character.  This implies that any increase in CPU and GPU power has extremely diminishing returns as far as the gameplay experience is concerned.

Nintendo certainly understood this.  The Wii is extremely underpowered for the technology that was current at the time of its release.  Rather than try to make a more powerful system, they created a new way of interacting.  This clearly is the future of gaming.  Microsoft and Sony are aware, as they have both announced efforts to create movement based interaction with players.  The downside is that Microsoft’s and Sony’s devices are not slated for market anytime soon.  Where as the Wii has an upgrade to movement detection that is to be released later this month.

Micrsoft has Project Natal which is by far the most ambitious and exciting.   If you haven’t seen this yet, you should certainly check it out.  It’s cool, freaky, scary and exciting.  The camera device is a 3D camera.  It is capable of facial and voice recognition.  It builds a live wireframe repesentation of your body.  It is also able to seperate you from background image noise.  I doubt it will deliver as that kind of technology would surely have shown up else where before being seen on a gaming system.

Sony has their upgraded EyeToy which looks to be much more feasible.  It involves a wand as the main source of tracking information.  This should be able to make it to market before Microsoft’s solution.

While all of this innovation is extremely exciting and certainly needed, I foresee problems…

I own a Wii.  I use a used gamecube controller to play every game I can on the Wii.  This is because using movement based inputs is an extremely annoying and inefficient input for many games.  The best example for me is Super Smash Bros. and Mario Kart.  I use the Wii Mote as a form of handicap when playing with family members.  When it comes time to unlock tracks, I pull out the trusty game cube controller and proceed to dominate.

I don’t want to have to swing my arm or shift my foot for every little task.  Can you imagine playing an RPG (role playing game) where every time you interacted with a chest you had to literally open an imaginary chest?  It would get ridiculous.  You don’t have to look to a crystal ball to see this.  How many of you have resulted to flicking your wrist when playing the Wii?  How many of you play Tennis or Bowling while sitting back in your comfy sofa?  Being up and mobile is fun for a while, but it certainly gets to be a chore.  (If I wanted to simulate the real thing, maybe I would, oh you know do the real thing?)

Here in lies the challenge.  How can they create engaging, fun and quality games that use their interaction devices without coming off as gimicky?  My thought is that you will see certain genres transfer better than others.  As can be seen on the Wii, timing based repetitive games fare really well with this form of input.  A ton of crappy wrist-flicking-infra-red-sensor-pointing games have been released for the Wii.  I’d venture to say they are all terrible and not worth your money, but they are certainly out there.  These games provide short intense burst of “entertainment” in a few varieties and then rinse and repeat until you get bored.  Where as a friend and I would sit down and play a  video game for hours on end.  With the Wii you find yourself bored and tired after an hour.

I’m starting to ramble…

The controller will not disappear.  It is a fantastic input device for many many many genres.  Movement should provide growth in a number of genres and perhaps even invent its own genre.  As movement detection technology improves, at what point does the game stop being a game and move into a life simulation device?  That would be the main element I find missing more and more in games.  The “fun” or “game” element.  So many games that are brilliant in nature end up feeling like work or a pixelated version of real life.

I see this ending up in a cycle.  Humans use “Virtual Reality” to react to a virtual world as a means to escape their problems in the real world.  Before long, they will try to create a means to escape the pressures of their virtual world.  How long before we play pong on a simulated Atari in some virtual world that we are interacting with through Nadal/EyeToy/WiiMote?

A little too deep?  Here’s a Kitty.
