I also laid a brick on each corner of the support grate (below the fiberfill). As the fiberfill loads with gunk, the upward water flow tends to lift the filter box. The weight of the bricks prevents this. In addition, I secured each long side side of the lid with a wire tie mid-way, drilling a small hole through the lid and box edge. Again the upward flow of the water against the partially loaded fiberfill tends to bow the lid in the middle and lift it. I am hopeful that these two mods will allow the filters to run all season with no attention.
For the upcoming season, I decided to replace the bulk loose polyester fiberfill with a "blanket" type (see photo), also from Walmart. The loose fiberfill is a pain to remove once it is wet and filled with gunk since there are many pieces. Hopefully, the blanket can be rolled and removed as one piece. One blanket can be easily folded to fit one filter box.
Battery is 2.2Ah, 11.1v, therefore, 24.42 wh.Light draws 100w, therefore, (24.42/100)x60=14.6 minutes to full dischargeAbout right?

How to build another useless machine: easy to make, and hard to use!
I solved a similar problem somewhat differently. My original corded wall phone did not have a nearby receptacle. When I installed a cordless phone, I cut the plug end of an extension cord and connected it to the hot wire feeding the switch underneath, along with the neutral (see photo). I then plugged the transformer into the receptacle end of the cord and tucked the whole thing into the wall. I know, codes, codes, codes. It's been 25+ years with no problems. The photo is of the 2nd and newer cordless phone.
That's why God made adjustable wrenches.
Yes, chlorine is a poison. Which is exactly why it is used and why, unlike many parts of the world, our water, with few exceptions, is safe to drink. Nothing like unsubstantiated paranoia.
Install an under-the-sink reverse osmosis unit. Much simpler long term than this tedious method.
Since chlorine is a gas, it's very difficult to sprinkle. Perhaps an instructable ....?
Actually the battery will have more than rated capacity at current draws less than the 20 hour rate due to the Peukert effect. The reverse is true as well.Also, "watts an hour" is meaningless. A watt is a measure of power, which is energy per unit time, already a rate of energy flow.
If the loss is 30%, the correct calculation is 365/(1-0.3)=521 (not 475). This is 10% more than the calculation shown.
The best time to go after a nest is after dusk when the critters are all in the nest. During the day, many are out and about.
You nailed it. Not just "chasing your tail," but a net heat gain.
The ice in the soda bottles melts. It does not evaporate. There is no evaporation. The discussion regarding "swamp coolers" is irrelevant.
Heating the kitchen to cool the bedroom? Actually, that is kind of silly. Especially since the cooler, denser upstairs air will fall and the warmer, less dense kitchen air will rise making both rooms about the same. Maybe an airlock to isolate the bedroom?
I used Command brand hooks, three for the largest lid. Completely removable - no permanent impact.
Not hardly! Air is 78% nitrogen, which doesn't change. The oxygen (21%) combines with carbon and/or sulfur to form CO2 and/or SO2. No change in the moles of gas. If this works, it is likely because the air is heated, allowing some gas to vent. When it begins cooling, the egg likely forms a seal, allowing a vacuum to form in the bottle, pulling in the egg.
Not a bad idea. Maybe rough it up a bit with sandpaper first to help it stick.
Testing the water is not necessary. By the end of the season, when I remove the pump and drain the header pond, the lava rocks have become coated/filled with algae and muck. They become a solid mass by Spring. Without cleaning, the flow would be blocked and the surface area for bacterial growth greatly diminished..Cleaning the poly-fil for reuse is virtually impossible and definitely not worth the $10, or so, annual cost.
