Features of light catching

And in general, these AWACS are the last century.

The last one may be the last one, but at the moment nothing is more accessible and effective for luring insects into the light has not been invented. For example: now yellow lights are being screwed into lanterns everywhere DNAT like more modern technologies. But one bad thing: it does not fly on such lanterns of shit, but if the lantern with DRL: that flies at it in the same area as many insects as you want. The standard conclusion is: why reinvent the bicycle if it has already been invented a long time ago? I don't understand.....

Ty, well, just stoko just)) Yes, connect a capacitor instead of a 400V 20uF choke for 125 W drl and that's it, the capacitor weighs 50 grams, tin ))))))))))

and to buy for your own - somehow I don't want to set fire to it just once. Yes, and suddenly it will not tan, all the more pathetic.

Is it a pity to spend 100 rubles for an experiment? And how much is spent on batteries?

My suggestion about sending one DRL-125 is removed - I suggest sending 10 lamps DRL-125.

OK, and for DRL-250?

Is it a pity to spend 100 rubles for an experiment? And how much is spent on batteries?

My suggestion about sending one DRL-125 is removed - I suggest sending 10 DRL-125 lamps.

Thank you for the suggestion! However, I have too little time left before the trip, after the trip I will try to dig into the bins of my homeland, maybe I will find it.
Again, Vaughn Roma advises conder...

DNaT not to say that much sovremennaya lamp, the same last century. it just has a large lumen output compared to drl about 2 times.

For 250 30mkf, and what is there to advise, all the time so connected, here I have now DRL 125 through a 20mkf capacitor is turned on, the current is 3A, minus the reactive power is somewhere 200W on the lamp, ie too much, but it burns cool )))
DRL 125 costs us 1 ue, is it really more expensive and more scarce in Perm, I can't even imagine how to send it and why

In general, it's okay for me to go fishing, but the rest of them spend the night here)))))

DNaT not to say that much sovremennaya lamp, the same last century. it just has a large lumen output compared to drl about 2 times.

Here-and this suggests that the number of lumens does not play any role for catchability, but the radiation spectrum and the presence of an ultraviolet component in it play a role. And the most suitable, time-tested spectrum for mercury sources (DRL, lum.
And all these LEDs and other "onanotechnologies" somehow do not cause much confidence, despite their obvious advantages for human eyes.

Roma, why do you go fishing on a working day?! Here say thank you that not I have you nachyalnika!)
Yes and what night, I about 8utra before work the first time on a forum came, and now the second on morning tea.

In general, I have a serious question. Here Vasily puts drl and lum on a par.tubes. But the usual lum.tubes do NOT give UV, but they give little and the amount increases as you age. UV tubes give uv, but as I was told that is not the one, namely uv-C.
Hence it turns out that lum.tubes are also not particularly suitable.

I wrote about the lumen of the dnat because it was said that it is more modern. However, in our production, a lamp with such a nasty spectrum is prohibited.

Well, again about the drl. And what is not drl-mgl in a double flask. If you cut down the first one, then the second one remains and it also gives uv, and by mgl it is already epr as much as you want.

Do you have that at 5 o'clock-this is about 8? Or in Perm, the time is different, not Moscow, like the time lords leveled everything there for you

And the difference between lum. lamps and DRL obvious-lum. tube lamps are low - pressure, and give almost one hard UV-C. Yes, and through ordinary glass it does not pass absolutely. But insects fly to them perfectly

Roma, we have a difference of 3h. From Moscow +2h.

Yes, I understand the differences in the design of lamps, you would rather say why it flies on ll??
An explanation?
Do they pass UV-A in small doses? The conclusion I do not see another. Ie lumki it is also "produce" in abundance.

I don't know why it flies on them, but it flies perfectly, I caught it on housekeepers for several years, and regularly compared it with DRL - there was no difference, but butterflies and beetles flew all sorts of things so I can't even open my mouth))) Only the truth I prick DRL included for comparison.
This is all theory, turn on and shine with what you have)))

"Throttle" for DRL 125, weighs 100g, exclusive-products of the local condenser plant. For sale, exclusive, 300 RUBLES

This is all theory, but it is necessary to turn on and shine with what is there )))

I confirm: I myself catch a 15w tube on my balcony Repti Glo 8.0 + 2 black savings banks of 26w each. And it flies quite well for the center of a city of 150 thousand people.

In short, thank you all!
This is all in order to still decide what exactly to take with you, because for some reason I feel that the next trip to Tai will be very long and I still want to catch.
All plans have changed today, the flight was postponed to the 9th of May.

Lanestris suddenly arrived on DRL-ku:



It seems that it was not given for Cupid...

Lanestris suddenly arrived on DRL-ku:


It seems that it was not given for Cupid...

yes, it is known from the lower Amur and Primorye, from the Amur region. no data available.

After returning from Thailand, you can sum up some results.
Everything is purely based on my feelings, I do not pretend to be a theory or truth in the last instance.
At 10W sd, insects fly! At 6W compact uv-A, insects DO NOT fly.
Combinations were tried:
- 10W Chinese sd;
- 6W cfl uv-a;
- 10W Chinese sd + 6W cfl uv-a;
- 10W sd in one direction, 6W cfl in the other.
In all cases where the 6W cfl shone separately or in a different direction from the 10W sd, the insects flew away or flew to the side of the sd.
After all, they were interested in the exceptionally bright, directional and far-penetrating light of the LED!
Hence the conclusion: the use of sd makes sense and has far-reaching prospects.
Given the kosyachnost Chinese dm, I plan to put 4-6 cml and get a multiple increase in efficiency.
I don't have enough power for the whole night, so increasing the lamp power to 20-30W is quite acceptable.
One-way light will do fine, because the light in 4 directions will simply blind the observer, I don't see the point in looking for a rectangular hollow radiator and putting diodes on all 4 sides.

I would like to mention one interesting fact for fans of fishing on lyumki. Street lighting is made in the form of linear 36W lumlamps! And nothing flies on them except small midges!! This caught my eye almost immediately, especially when I was walking along the road to the hotel at night.

Specifically, the execution of the lantern suited me to everyone.

It is easy to fasten on a tight cord for the screen. However, it will go to the aquarium, and something else, more powerful, will be made for fishing.

But the execution of blocks for batteries failed me.

And it's not even a matter of the connector coming off, but of poor-quality contacts that did not fit snugly.
Now I redid it like this, filling it with liquid nails, then I'll paint it with something black.

The dc 5.5x2.1mm connector was glued with superglue, and then filled in with nails. Before leaving, he did not have time to come from China, probably walking.


The Chinese USB converter did not let you down for a minute! It perfectly charged the phone on the plane, perfectly powered the flashlight, it charges the batteries quickly, faster than a special. more expensive charger.
Output 3.6V5V9V12V15V16V19V21V24V 3A/2A Mobile Power USB 18650 Battery Charger

Paired with high-quality Japanese batteries, it will give you the opportunity to use your tablet/phone/laptop for the entire multi-hour flight! In the case of a phone, then multiple round-trip flights.
I advise you to buy without a charger, take the charger separately, but always 16.8 V. I also have a set of shoelaces lying around in vain, i.e. I don't need it.

And here's what the whole experience looked
like

I kind of forgot yesterday.

I experimented with the Chinese charger-power supply from the previous post, connecting different currents and voltages.
This unit is very much heated already at a current of 1.5 A 24V, which makes its use impractical! Moreover, this unit can only handle such a load on Japanese 3ACH trastfires! On other batteries, it works somewhere up to a current of 1A 24V.
I used a terra cover as a load, which consumes 1.5 A at 24V or 36W.
It is clear that I did not kill a cool phone charger in field conditions and quickly turned it off, not allowing it to melt. Let me remind you that there are 4 batteries in the charger.

Not Japanese trastfares 6pcs 24V 2.4 Ah-nominal, at a current of about 0.8 A actually give-2Ah, at a current of 1.5 A lasted 1h and noticeably so heated.

We draw the rest of the conclusions for ourselves.


I remember someone here threw out a big Chinese battery pack. What a pity!! Although it is a little fast, but most of all there are dumb chargers in the kit that are not able to charge this unit.
Rechargeable 3800mAh Lithium Ion Mobile Battery Pack & DC Connector, 12-volt 12v

Purchased separately charger 12.6 V 1.5 A my unit with the specified rating of 3.8 Ah (on the accumulators in the pack says 1650mah) charges normally and quite quickly. In reality, the block gives about 0.8-1Ah.
I wanted to fill the case from this unit with a decent and more capacious filling. It turned out not quite what I wanted, but still a little better.
For clarity and to remember what it is about

The accumulator block began to look like this, do not throw away the same good

I bought these batteries on the dial, which turned out to be quite shitty, and assembled them into a block

with a charger 4A-5A PCB Charger for 3 Packs 3.7V Li-ion Li Lithium 18650 Recharge Battery with midpoints to avoid overcharging

On the heated mikrukha in the center put a simple radiator.
The result was something like this



Those who decide to build a lithium pack with this or a similar device should take into account that it is not enough to remove the load to turn off the handkerchief! The chip in the middle remains energized and works! I.e. to disconnect the board and save battery capacity, you need to put the switch on one of the extreme ends of the battery, I put it on plus, i.e. the number of switches should be equal to the number of blocks, there should also be a central switch of the entire battery, so as not to overload individual blocks or simply disconnect the output-input connector (the battery is charged and used via the same connector).
The charge voltage is 12.6 V for a pack of 3 batteries, 16.8 - for 4x.

Well, the result was such a power unit

True, its capacity is only about 1.6 Ah at a current of about 0.8 A.

For those who want to transport their own power sources to other countries, it is worth considering that your packs must be collapsible!! To be able to present batteries for inspection at customs! Otherwise, there may be problems! Those. you will have to transport the pack case itself separately from the batteries!

ps
For those who are particularly fond of lumens, I would like to note that 1.5 A 24V is 36W, i.e. 6 batteries (2 parallel units of 3 batteries connected in series) of 18650 are capable of about 1h pulling a linear 36W lumens to 12V epra, which I described above in the topic.
6 batteries weigh about 273g.
For fishing in the snowless season in our country, it is enough to take only about 3 kg of weight with you: a lamp, batteries and a launcher. Anyone can do it.

Hello everyone.
Need advice on how to catch Oryctes nasicornis in the light?
I came to the village, here a week ago 2 beetles flew into the house.
At night, I stretched a sheet with a UV lamp (blue, "quartz")
I burned my eyes, and all sorts of moths and small butterflies flew
up from 1 nasikornis.
what did I do wrong?

In general, it is not a fact that you will immediately catch a mass of light.
If there is compost, humus, old sawdust nearby, then it is better to look there.

Who has experimented with night-time scoop fishing with a net and a headlamp? I tried it myself a week ago. I caught 15 scoops in an hour from 23 to 24 hours and this is during the full moon.

I caught it sometimes before in this way, when it was not possible to use the generator. Usually it's not bad when you catch in a blooming meadow, as in the photo.

Of the minuses-until the butterfly is in the net-you can't see what you're catching. Therefore, during the mass summer of the most common species, a lot of time is wasted. My opinion is that it is more efficient to catch the light.
Even at night with a flashlight, you can inspect the bait, here it is quite effective - you can choose what you need.

...if suddenly to whom.

and on alibaba, you can order a lot of cool devices, perhaps only fantasy and performance characteristics.

I used power storage myself (+a couple of LEDs in it) to recharge my smartphone, which was used as a nafigator with a satellite image, for this reason. So, it was enough for 8-9 full charges of the smartphone, which usually does not hold a charge for long - a couple of days. Or you can also order a thick battery for the phone, they said-it seems to hold for a week. a smartphone with an energy storage device-in total met 5 thousand, (the most inexpensive decent hb. nafigator only for the track - the same amount), and in the phone there are also photos, videos and sos (if anything, ugh*3))

I've already experimented. For smart, there are two charges that will last for infinity.
For fishing, if there is a fishing rod, there are already a lot of batteries and a master sd searchlight ok 30W, everything is bought, but I'm too lazy.

Good afternoon or evening to all, who has what!
I constantly read about your experiments,I don't really understand electrical and electronics myself.Sorry, but I'm still interested in the final result.Have you come up with an optimal model that can actually be used for one night without recharging(approximately 6 hours)?And, if "yes", then what s / h are required to build one.

Have you come up with an optimal model?,

There can't be an optimal model, because everyone has different requirements and capabilities.

Optimum?
The optimum would be if instead of Chinese diodes and useless Chinese 18650 batteries, I would buy Japanese batteries and useless LEDs!
And so I plan to shine 6 hours with the manufactured 30W led flashlight.

Yes, you in general, as it is noticeable here, are cool in electronics ... I wish I knew something about it.
We are waiting for our universal happiness in the form of a ready-to-use recipe that does not require special electro-knowledge and difficult search for details...

My coolness in electronics ends with the ability to solder)

In addition to the ability to solder, you need to know what you are soldering and what you are soldering to.

This is also available.

I need some advice.
I used lamps that run on a 12 V battery. But Chinese carriers from the car market turned out to be very unreliable - after two hours of operation, the parts on the board are very overheated, the burnt insulation starts to stink and the lamp goes out. So I have already collected 4 such lamps. I post photos of lamps and the filling of the lamp in the hope that someone can advise-suddenly you can replace some parts on the board (if they are easy to get) and fix this miracle of Chinese technology. It was at one time exactly the same, but it looks like European production, like those that are sold on bioform at an exorbitant price. The device inside it was exactly the same, but it never had any problems.






In my opinion, the source of overheating is a part similar to a miniature transformer. The electrical tape was melting on it.

Listani nesk.a year ago, there Hierophis gave tips on setting fire to lumens, simple and reliable schematics.

But I can't bring myself to finish picking up my sd lamp. No way. Only cooler on the radiator priventil))

I read it. But I didn't understand everything. Maybe it will be easier to fix the Chinese scheme?

Well, if you want to look for this chip / transistor and possibly rewind the transformer, then you can. In general, it is better to throw out and no longer mess with Chinese disposable products (if there is a choice, of course).

More precisely, with Chinese disposable products made for the Russian consumer and bought in Russia, because Chinese products are not for Russia and not bought in Russia are not disposable at all.

Not necessarily for Russia: Chinese manufacturers meant all sorts of companies like "Hun Wing Bin" or when nothing at all except Made in China is no secret that most well-known companies produce their products under control in China and this has little effect on quality..... Okay: I don't see the point develop a discussion from scratch.... I went to work.

Dooooo....
Chinese batteries purchased on eBay turned out to be particularly high-quality.

Well, those purchased with dh are also quite high-quality. And again, with ibey, not everything is of poor quality.
Take the electronics that I took to ibei. All Chinese, but everything works fine. Take a Chinese timer from a local store-constant failures and eventually gave it away. And this is just one example.
I also have a lot of the same batteries...

Dooooo....

And how did the lamps from Ento Sphinx work? I remember you wrote about them. I looked at them yesterday , but the lamp marking is not visible in the photo, and there is nothing in the description. And it is not yet clear how to order and pay for them. We have a kingdom here with its own peculiarities, maybe it will be easier to order from Russia.
If the lamps are "Actinic", then I would buy.
