They’re Gnat my Problem Anymore

I know, cheesy title. It made me giggle so I do gnat care. It was a silly way to introduce a serious problem. I want to relate the beginning of my gnat problem and how it has been alleviated. Who knows? Someday this might help someone out.

1440091556041Several years ago, I worked with a woman that had a large vase on her desk that held a beta fish. I was surprised how much I enjoyed watching that stupid thing swim around his confined universe. I thought it was interesting that she also had some ivy growing with the fish. The ivy was fertilized by the fish excretions while it filtered the water. Neat!

I happened see some beta fish at Wal-Mart several months ago and remembered how much fun I had watching the one back at the office. I bought a fish and ivy and went home to set everything up. All was well, but I had much more ivy than I needed AND it kept growing. I became somewhat fascinated and began experimenting with different ways to increase its growth rate. More ivy led to more pots and more wet potting soil. That led to gnats. I know they are small and just an annoyance, but they are an exceptionally annoying annoyance.

My researched on gnat elimination produced a number of commercial and DIY options. I didn’t like the commercial options because they all had fairly short life spans, mixed reviews, and required stocking more stuff in my pantry. I didn’t like the DIY options (mostly a water bottle cut in half and  taped back together like a funnel) because they didn’t look nice.

After more research, I found a guy that was fairly scientific about testing the commercial and DIY gnat eliminators. He planned to try about 10 different options and record the number of dead gnats from each. About halfway through, his experiment was cut short because he accidentally left a bottle of wine open one night. The next day there were no gnats for further experimentation. It turn out wine is more than just a healthy, wonderful meal.

My final solution (pictured to the left of the fish) is a combination of wine, dish soap, and a twist on the DIY water bottle funnel . I used a wine bottle instead of a water bottle for asthetic reasons. I “simply” cut it in half, flipped over the top, and stuck it back in the bottom. “Simply” is in quotes because I found that step to be anything but simple. The wine is for bait, and the dish soap is a surfactant to reduce the surface tension of the wine. Without surface tension, the poor little drunks sink to the bottom rather than floating on the surface with the ability to haphazardly fly away in a drunken stupor. I thought I was going to need to put a seal between the wine bottle halves to trap them, but that hasn’t been necessary. Each sinks as soon as it lands, hiccuping its way to an intoxicated demise.

If you want me to make one of these for you, bring me a unopened bottle of red wine and give me a couple of days to get the trap back to you. When making the wine bottle selection, keep in mind that the effectiveness of the trap is directly related to to the price of the wine. Expensive wine bottles make much better traps.

Let’s Mix Things Up

KIMG0063For some reason, I have been fascinated with KitchenAid mixers since I was a little kid. I think it is because my parents had a large Hobart mixer at their restaurant, and I thought the smaller home edition was novel. Or more likely, they have gears, mechanical attachments, and a motor… three of the things that are dearest to my heart.

I bought one a while ago from Craigslist, and it leaked oil the first time we tried to use it. After getting over the initial horror of oil dripping into the dip we were concocting, I read up and found out this problem is fairly common. KIMG0064The grease they used breaks down over time and becomes a combination of a cakey substance and a fairly thin oil which drips from the case. I disassembled it, replaced the grease with Food Grade Machinery Grease, and all was good. This was about a year ago, and there has not been another drop of oil.

Tonight I was at a good friend’s house, and she mentioned she was having the same problem. She was even thinking about getting a new KitchenAid. I brought it home, did the same procedure, and it is now as good as new. I am posting this as a public service announcement. Don’t throw out your KitchenAid mixer if it drips oil! It is a fairly simple fix.KIMG0065

I included some pictures of the inside in case you’re curious. I know that I was. I didn’t include a picture, but it also has an interesting electromechanical governor system that adjusts the power delivered to the motor to maintain the selected speed under varying load conditions.

A couple more things:

  • Yes, the pictured mixer is purple.
  • No, it is not mine. Mine is much more masculine.

Can you tell what this is?

1439408558718It looks like its on its way to being a fire pit, right? Well the cats seem to have a different idea. I assume you can tell what is pictured on the left. They obviously think I like them SOOOOO much that I would buy 600 pounds of concrete and mortar, 1000 pounds river rocks, work mortar until my fingers and hands were cracked and dry, and brave some of the hottest recorded days in Houston to build them a stone litter box. I bet they are bragging to the strays and gloating to the chickens about it right now.

Regardless, I finally have a fire pit. I decided I wanted one about 2.5 years ago, and I’ve been overthinking it ever since (refractory clay? foundation? rebar? will the rocks crack? how big? vents?). Since I am never going to be more jobless than I am now, I went ahead and pulled the trigger.1439062273636

I decided to use regular mortar rather than fire clay because mortar is free relative to fire clay. If it doesn’t stand up to the heat, I will just patch it back together. I did decide to build a foundation, but I did not use rebar. The foundation is a ring and is about 5″ deep (though it looks much shallower in the picture to the right). It took 240 pounds of cement just for that.  Do you think the cats are already plotting?

After letting the concrete set for a day, I began piling on the rocks and mortar. I am not sure I got the consistency exactly right, but it seems to be holding. I was using a trowel religiously until I discovered that I am not gifted with a trowel. I started using my bare hands after the first layer. BAD IDEA! I thought my hands were getting pruney due to the wetness of the concrete. Instead, there was some kind of chemical reaction.  My skin started cracking after about a day. I did some research, and the pH level of cement is 12-13 whereas human skin is 5.5. Then I read the label. God Bless Texas, because it said that I could have gotten cancer if I was in California.

KIMG0058Here is the finished product, although some of the mortar is still drying. The pit itself has an ID of about 4 ft. and a height of a couple feet. I included some vent holes by mortaring in 1″ PVC pipe and pulling it out after the mortar set.  In addition to ventilation, I may use one of the holes to plumb black pipe if I decide to build a propane burner for easily starting fires and/or cooking.

I want the fire to be above ground level, so I have also built a grate. This was intended to serve two purposes. It raises the fire above ground level and lets air get to the embers. I was about to finish by welding legs and a truss for supportKIMG0062, but I started getting nervous that the grate might not be a great idea. My concerns relate to the fire getting too much air, burning through wood too fast, not having the insulation of the ground, and losing that campfire feel. Rather than welding on legs, I am going to place it on blocks for a test run. It will become a cooking surface if I don’t like how it acts.

I’d like to close by offering my advise and ridicule if you ever want to build something like this. Notice I did not offer my help. It was much, much more of a pain than I ever imagined.

I Might Be an Alien

KIMG0054That title might seem confusing… especially since it relates to chickens.

I didn’t buy my pullets as chicks. I bought them as adolescents, so they spent their childhood years (months) solely with other chickens and had minimal human contact. This makes them uncomfortable around humans, at least during the day. That led me to a loophole. When they roost at night, they are trapped in the coop. My idea has been to pet them at night when they were confined, docile, and hypnotized with sleep. I figured this would make them comfortable with human handling.

Then, I started thinking about it from their perspective. Late each night, I:

  • Silently approach their chicken tractor
  • Turn on a bright flashlight
  • Remove their roof
  • Proceed to probe at them
  • Sometimes there is a cat involved, other times there isn’t
  • Replace everything, like nothing ever happened
  • Sneak away

That creepy scenario didn’t even include the magic automated chicken door that locks them in at night and lets them out in the morning.

Except for the cat part (I’ve never seen an episode like that), Doesn’t that sound like being on the wrong side of an X-Files episode? From their point of view, I think it might freak them out more then tame them. I just wish I could understand their conversation and what they have been saying around the water bowl. I hope I haven’t traumatized them so badly that we can’t share a laugh about it several years (months) down the road when they are mature adults and have lost their adolescent angst.

Moving forward, I am going to give up on the late night visitation approach for winning their friendship. I am just going to bribe them with meal worms. I bought some today, and those things are like crack for chickens.

Next Boost Test

KIMG0048For those of you on the edges of your seats about the functionality of the cheap ebay boost controller, you can relax. It didn’t work. It would initially over boost before settling back down.  I took apart the tee, and found this (photo on left). I thought the tee contained just a check valve, but the spring was strong enough that it acts as a relief valve. It would boost up to about 18 psi, crack open the ball, and then settle back down. I dropped the spring seconds after taking this picture, and it bounced off the shop floor and into oblivion. I don’t think that is necessarily a bad thing. I will explain.

 

The following three sketches show:

  • The stock configuration
  • What I thought I was buying
  • What I actually bought

The first uses an electric solenoid to control boost (which the Grand National tries to do blindly). The second uses a “Grainger Type” boost valve that is so named because one can modify parts from Grainger to make it.  I didn’t initially go this route because adjustment results in burned knuckles.  It consists of a simple adjustable home made relief valve. The third sketch shows the Cheap Ebay Manual Boost Controller (CEMBC) that I purchased. As shown in my last post, the CEMBC came with a tee and a variable orifice. Internal to the tee is a fixed orifice and relief valve. The problem was that the boost required to overcome the relief valve was greater than the boost I want to dial in. It was overboosting before the relief valve even opened.KIMG0049

Now for the next test. I’ve completely removed the ball and spring in what I call the Modified Cheap Ebay Manual Boost Controller (MCEMBC). I think that this will provide more accurate feedback to the waste gate actuator, and I do not think they are necessary if no vacuum actuated circuits are connected to that loop. I initially thought that this would cause inconsistencies between immediate Wide Open Throttle and rolling into the throttle more slowly. I’ve thought about it more, and now I think that its operation will be similar to a pneumatic version of a voltage divider. The signal to the waste gate actuator should be a nice, smooth percentage of the boost pressure.KIMG0050The only disadvantage I see to this setup is increased spool up time because it won’t lock the waste gate closed until it reaches the desired boost. Instead, it will open gradually. I think my final solution will be a combination of a “Grainger Type” controller and the MCEMBC. It will really depend on the adjust-ability of the fuel map when I get a chip I can tune.

This post really isn’t for the general populace. I just want to log what I am doing so that I can bounce it off of other car guys to see if they agree. I promise to make the next post about cats, chickens, interior decorating, or something along those lines.
