Features of light catching

But in the spring of 2011, my friend and I encountered more than once the phenomenon of extremely inactive summer in places that were previously rich in catches, both in quantity and in species composition. We used a 250-watt drl and a black housekeeper. There was an opinion that the black UFO did not attract anyone at all.

Well, that's right! just DRL "scored" the light of the black housekeeper

I also think that all these black lamps are bullshit. Just - this is my opinion - I think that an ordinary lamp is enough, and I have always done so.

Well, don't tell me! Igoran (one of my friends) posted on sayte video of fishing on a black tube, the result is impressive! The screen is literally strewn with scoops (in particular catokals), moths, and in the grass (as the voice-over said) pine hawks swarm (even crawled on it)! so I don't agree.

Entomon, all this is good, but you need good statistics and the presence of conrol - that is, how much worse/better was fishing for different lamps, that is, you need a comparison.
As it is, these are just isolated cases.

Sorry (, video no more

People! Please tell me the best batteries in the ratio of capacity /weight (respectively with inverse proportionality). Need at least 12 Ah, preferably with a low price.
It is planned to carry pekhom in a backpack.

Example: according to literature sources, C. dominula flies during the day, however, it flies very successfully on a punctured DRL, but on a non - punctured one-FIG.
...
Now about the "lightning rod". First, why do you think the lightning rod was invented in the first place? To kill under it or defend yourself under it?

The example with C. dominula, in my opinion, is not successful. This species flew to me on a non-punctured DRL, and last season several pieces flew to a diode headlamp while I was having dinner sitting in the woods near the tent.

As for the lightning rod, I think it means the rod with the lamp - and it's not grounded.

- The best ratio is found in lithium batteries.

Approximately 4 kg

Well, I already realized in principle that it is difficult to do with less weight. So that is 2 batteries of 7Ah, in the end the same weight and 2Ah more))

I will first try on them the scheme of a homemade converter for housekeepers from this branch.

Large-capacity lithium batteries are not enough, but it will not work to collect a battery from small ones...But if you build a battery from AA lithium batteries? For example, 1 piece is 1.5 v 2900 mAh(2.9 Ah) That is, 1.5 *8 =12 volts, and 8*2.9=23.2 Ah. Am I reasoning correctly?

Large-capacity lithium batteries are not washed,

Lithium, with a capacity of 20 Amps / hour, was recently discussed in this thread.

from AA lithium batteries ... 1,5 v 2900 mAh

Can I link to this element?

That is, 1.5 *8 =12 volts, and 8*2.9=23.2 Ah. Am I reasoning correctly?

Right. Get either 12 volts 2.9 Ah or 1.5 V 23.2 Ah.

Something really wrong...and it costs like a cheap generator probably 7

At 1.5 v, I mixed it up with a battery, lithium ones go 3.7 V, and Ni-MH 1.2 V, I thought both voltage and capacity are multiplied.....

That is, you won't be able to multiply both indicators?

I think it's worth digging around here.

The example is quite normal, but not fully voiced. In the north of the MO regularly, while catching on a non-broken DRL, single copies of dominula arrived. After installing a stab DRL, HUNDREDS of dominuls flew in regularly during the season per night! You can argue as much as you want, disbelieve and engage in various garbage with LEDs, but at the moment there is a split DRL; then there is a non-split DRL, and everything else is just a mess of dope

If from batteries of 1.5 v. 2.9 Ah, you want to get 12V. 23.2 Ah, then you will get not only gold, but diamond). Here is the battery connection diagram:

You probably have an A in physics at school. Yes, and in Russian, too. I wish all children were so smart and literate!

Are you sure this scheme will work? Something tells me that shorting the "pros" with "cons" will not end well

Oh yoo sleepy was) I didn't sleep at night and therefore drew such nonsense like this:

Well, not a five, but a four in both Russian and physics I don't like to teach), and at the expense of physics (more precisely, radio engineering), I helped my grandfather solder radio circuits from the age of three. It's a skill I got from my grandfather.

Entomon, again not so ))))))) You need to sleep more ))))

Dominula in my area is rare and just does not come, maybe in the south everything is different
As for the rod with the lamp, in the previously described version, it can quite easily be a lightning rod, since it is metal and is put on a metal pin driven into the ground. However, I don't even want to discuss all these childhood fears.

What's wrong?

What's wrong?

96V, 2.9 Ah

96V, 2.9 Ah

For a long time I have been looking and thinking how-is it with a serial connection that people want to achieve an increase in capacity? Only the voltage can be increased with this connection.
And to increase the capacity, it is necessary to connect in parallel, which is absolutely not recommended to do with either batteries or batteries. Or am I behind the times and not catching up on something? By God I don't know

96V, 2.9 Ah

Ugh... generally confused) connected in series sori, now exactly all the rules:

Ugh... generally confused) connected consistently sori, now exactly all the rules:

Now correct, but only theoretically. But in practice, I advise you to give up this idea with a parallel connection of batteries.

Ugh... generally confused) connected consistently sori, now exactly all the rules:

Theoretically connected correctly. But practically, the capacity of 23.2 still will not work. Due to the fact that real acc. have a spread of parameters, and thus, weaker parallel chains will hook stronger ones. In addition, when charging, the currents in different chains will be different and some of the chains will be undercharged and some will be overcharged.

Something really wrong...

Discussion on page 37.

In general, either order those batteries for 20Ah (and they need 4 pieces), or take lead.
Ah easier until yuzat 2shtuki on 7ach, available.
For a fishing test not far from home, since I live on the outskirts. And then we'll see.

Not everything is so sad With a higher rate of charging batteries with a lower internal resistance, but as they charge, their resistance increases and they begin to charge at a lower speed... The reverse process occurs during discharge. In short, a negative feedback system. And eventually all the batteries in the system will be charged/discharged to the maximum / minimum voltage. In addition, the serial connection largely averages the parameters of parallel chains. In general, both parallel and serial connection of batteries is widely used in technology from a car to a submarine, simply because the voltage and capacity of a single cell cannot meet all the emerging needs.
And even more: for batteries, probably, the capacity of "at least" the given figure is indicated, and not the average or maximum.

If you live on the outskirts of the city, then it's easier to get a generator and DRL, and the result will please you very much! When I didn't have a drl generator, I hung it on the balcony on the 9th floor. It was in Tver on the outskirts, around the house and other buildings, on the horizon of the forest, and then very good catches were obtained. And when I went out into the forest with an accomulator and a halogen lamp, I don't remember which one , I caught only two butterflies in two nights-riparia purpurata and catocala fraxini. so, in my opinion, it's better to hang the drl in the garden. But, of course, this is my personal opinion.

I hung an ordinary housekeeper on the balcony and caught a hundred types of shovels in a season, not to mention that every day butterflies flew in droves, as they say, "Paris, 25 years-nothing like that" (c))) But what a height there was! And if you catch from the ground, and even in the forest, then at least light the DRL there, even arrange thermonuclear fusion - the visibility of coverage will be limited.
So here the conclusion is quite different to make-you need to catch from a hill.

And for some reason okoem has a strange bias towards parallel battery connections, although in fact all the alleged shortcomings can also be attributed to a serial connection. with the exception of the alleged discharge of some elements to other elements, although there is no discharge, there is only potential equalization.

By the way, in fact, a separate battery can always be represented as a set of small batteries connected in parallel, it is enough, for example, to disassemble a lead battery and look at how it works.

And eventually all the batteries in the system will be charged/discharged to the maximum / minimum voltage.

And for some reason okoem has a strange bias towards parallel battery connections

In this case, I have a purely theoretical reasoning. Maybe I'm wrong, I haven't checked it in practice.

In the forest, I fished on a large bald spot, at the edge, a place that I think is very promising, a variety of grasses, trees, shrubs and undergrowth, and the lamp was just on a hill, And I advised about the balcony, because there were a lot of lanterns, and nevertheless it was caught not bad. And I don't want to mess with the battery anymore. Well, at least for now. The generator is 10 - 15 kg., This is one of the affordable ones, and the " com " weighed 12 . But you can connect the drl to the first one, and you need to do chemical work with the second one. Of course, we all need a pocket - type UFO source powered by nuclear batteries with 220-volt current generation, but ......

By the way, right now there are generators on hydrogen fuel. They give out 400 watts for 16 hours, after which they need to replace the battery. The battery costs $20. The generator itself is $400. Everything weighs about 3 kg. It seems to be cheaper and more environmentally friendly than using gasoline on conventional electric generators.

Wow, and where is such a miracle yudo sold? And what is the voltage? But this is probably not for Russia , there will be problems with hydrogen fuel, or does the battery itself emit it?

Moreover, the parameters for our purposes are quite unsatisfactory...

I designed a hydrogen generator like this:

When current is applied to the electrodes immersed in water, hydrogen begins to be released from the water, and then according to the scheme.

True it can break

It was you, my dear, who designed the perpetual motion machine. It is better not to discuss its technical implementation at all...

Entomon, well, the idea is cool, but not everything is so simple Even here at least the extraction of hydrogen by electroplating-and then there are nuances, you need it so that it does not interfere with oxygen, otherwise it will definitely explode )))

Well, a perpetual motion machine is certainly cool, but so far it is unattainable, although...
Here, I ksttai just took a picture from my window of a cool source of energy on hydrogen fuel!!!
Almost eternal, powerful, however, can jerk

Yes, I did not make a perpetual motion machine , the water will need to be changed, but without air it will not work. Yes, and little hydrogen is released, small explosions will occur inside the engine, as expected.
