For an amazing boost in wifi signal, make yourself one of these. You just need an old Directv or Dish type satellite dish, a few cheap parts and a little time. There's a lot of info on them to be found, just do a search for wifi bowtie, or wifi biquad.

Nice link! Thanks!

It appears that there are pictures that should come up but I can't get them to load. I guess I'll have to try them at home. I just happen to have a 'dish" antenna that was left to me by the previous owners of the house. I can't wait to make it useful!
Great Link !

Icu4dzs, the battery is super simple to make. Im using 4 inch pieces of 10 ga. solid copper wire and 1/8 to 1/4 inch wide strips of galvanized roof flashing, cut out with metal cutting sheers. You can also use galvanized nails. The electrolyte is epsom salts and water, as strong of a concentration as will dissolve. The copper and metal electrodes are suspended vertically in the solution. Copper is positive and iron or zinc is negative. I'm hooking up 4 jars in series to get about 3.5 volts. I have 5 sets of these hooked in parallel to boost the current. There's a total of 20 jars. If you just hook up 4 jars in series, it will light an LED. For my first prototype, i just stuffed plastic grocery bags down in the jars to keep the electrodes from touching. A bit of old speaker wire to hook them together. It's very easy to make one in less than an hour's time.

I still haven't found those plastic lids yet.

I still haven't found those plastic lids yet.

We have a store out here that sells farm supplies called Runnings. Mills Fleet/Farm is another. I get them in the canning section of that store.

Do you dissolve the epsom salt in warm or cold water. It matters. If you use hot water you can get more dissolved. A super saturated solution will have more electrolyte in it and ostensibly last longer.

[sunsaver]

Yeah, super saturated. When the water starts to evaporate from the jars, white crystals form on the glass and electrodes. It doesn't hurt it. Just refill with water. But i want lids to make it a sort of permanent, maintenance free battery.

 

[valmom]

SS- you can find the plastic mason jar lids anywhere canning supplies are sold. I saw them in the grocery store, the local feed store, and Agway.

 

[sunsaver]

Thanks, valmom! My feed store didn't have them, but i'm going to the grocery in a little while to get some shrimp. I'll look for them there.

 

[sunsaver]

I had to give up on the search for plastic lids. Don't think they've made it to this town yet, so i bought some regular mason jar lids and stuck with the original design. I decided to use 8 awg solid copper wire and large galvanized nails for the electrodes. The silicone sealant is drying, and in an hour i will use one of the cells to try different electrolytes: salt water, vinegar always works good but may react faster than i want. Plain salt is cheaper than epsom salt, so that would be good. I'll take a few measurements then wire up the battery. The whole time i was putting it together, i kept thinking, 'this is so cool!'

SS,
the plastic tops are called "Plastic Storage Caps" made by Ball.

This should help you get them. They are really useful for a lot of things but I am guessing the insulating properties and the fact that they won't corrode with the current passing through will be a substantial benefit.

Earth Batteries

A simple homemade cell is the earth battery. Almost any liquid or moist object that has enough ions to be electrically conductive can serve as the electrolyte for a cell. As a novelty or science demonstration, it is possible to insert two electrodes into a lemon, potato, glass of soft drink, etc. and generate small amounts of electricity. As of 2005,
"two-potato clocks" are widely available in hobby and toy stores; they consist of a pair of cells, each consisting of a potato (lemon, etc.) with two electrodes inserted into it, wired in series to form a battery with enough voltage to power a digital clock. Homemade cells of this kind are of no real practical use, because they produce far less currentand cost far more per unit of energy generatedthan commercial cells, due to the need for frequent replacement of the fruit or vegetable.

It consist of conductive plates from different locations in the electropotential series, buried in the ground so that the soil acts as the electrolyte in a voltaic cell. As such, the device acts as a rechargeable battery. Operating only as electrolytic devices, the devices were not continuously reliable owing to drought condition. These devices were used by early experimenters as energy sources for telegraphy. However, in the process of installing long telegraph wires, engineers discovered that there were electrical potential differences between most pairs of telegraph stations, resulting from natural electrical currents (called telluric currents) flowing through the ground. Some early experimenters did recognise that these currents were, in fact, partly responsible for extending the earth batteries' high outputs and long lifetimes. Later, experimenters would utilize these currents alone and, in these systems, the plates became polarized.

It had been long known that continuous electric currents flowed through the solid and liquid portions of the Earth and the collection of current from an electrically conductive medium in the absence of electrochemical changes (and in the absence of a thermoelectric junction) was established by Lord Kelvin. Lord Kelvin's "sea battery" was not a chemical battery. Lord Kelvin observed that such variables as placement of the electrodes in the magnetic field and the direction of mediums's flow affected the current output of his device. Such variables do not affect battery operation. These metal plates were immersed in a flowing medium and created a magneto-hydrodynamic generator. In the various experiments, metal plates were symmetrically perpendicular to the direction of the medium's flow and were carefully placed with respect to a magnetic field which differentially deflected electrons from the flowing stream. The electrodes can be assymmetrically oriented with respect to the source of energy, though.

To obtain the natural electricity, experimenters would thrust two metal plates into the ground at a certain distance from each other in the direction of a magnetic meridian, or astronomical meridian. The stronger currents flow from south to north. This phenomenon possesses a considerable uniformity of current strength and voltage. As the Earth currents flow from south to north, electrodes are positioned, beginning in the south and ending in the north, to increase the voltage at as large a distance as possible. In many early implementations, the cost was prohibitive because of an overreliance on extreme spacing between electrodes.

It has been found that all the common metals behave relatively similarly. The two spaced electrodes, having a load in an external circuit connected between them, are disposed in an electrical medium, and energy is imparted to the medium in such manner that "free electrons" in the medium are excited. The free electrons then flow into one electrode to a greater degree than in the other electrode, thereby causing electric current to flow in the external circuit through the load. The current flows from that plate whose position in the electropotential series is near the negative end (such as palladium). The current produced is highest when the two metals are most widely separated from each other in the electropotential series and that the material nearer the positive end is to the north, while that at the negative end is towards the south. The plates, one copper and another iron or carbon, are connected above ground by means of a wire with as little resistance as possible. In such an arrangement, the electrodes are not appreciably chemically corroded, even when they are in earth saturated with water, and are connected together by a wire for a long time.

It had been found that to strengthen the current, it was most advantageous to drive the northerly electropositive electrode deeper into the medium than the southerly electrode. The greatest currents and voltages were obtained when the difference in depth was such that a line joining the two electrodes was in the direction of the magnetic dip, or magnetic inclination. When the previous methods were combined, the current was tapped and utilized in any well-known manner. In some cases, a pair of plates with differing electrical properties, and with suitable protective coatings, were buried below the ground. A protective or other coating covered each entire plate. A copper plate could be coated with powered coke, a processed carbonaceous material. To a zinc plate, a layer of felt could be applied. To use the natural electricity, earth batteries fed electromagnets, the load, that were part of a motor mechanism.
