Everyone brain friends, good day! Here is a guide on how to create another one brain lamp, which, however, stands out from everyone else with its “coldness” :).
I collected three of these "cold" homemade products, each of which glows in its own color, and I believe everyone can with your own hands make one like this for yourself.
For this you need (components are designed for 3 lamps):
- several spare parts from a copper lamp
- three bulbs from 300W light bulbs (small or large, your choice, or you can glass bottle or something similar)
- 6 UV LEDs and resistors for them for 9V
- 3 9V batteries
- 3 switches
- textile braided cable
- acids and potassium sulfide for coloring
- thin wires
- distilled water
- glue gun
Step 1: Stand or Case
First you need to separate the bulb bulb, and there is a lot on how to do this. brain guides. Be careful and careful during this process, as the glass of the flask is very fragile!
The second photo shows pendants with empty flasks, and the third with painted bases.
Next, we glue a UV LED into the stand, directly under the bulb, and solder the second UV LED in parallel using a braided cable. Leave this cable long enough so that it can be trimmed if necessary.
Step 2: Flask Holder
By connecting your brain fantasy We make three flask holders, I made them in the form of spirals.
Then, calling Dremel and Proxxon to help :), we cut the test tube to a length of about 10cm.
We drill a hole in the test tube stopper for the second UV LED and glue it in using a glue gun.
At the same time, we “invent” caps for the test tubes, for example, as in the second photo. After that for each brain trick we mount the switches and connect them to the LED circuits (third photo).
Step 3: Filling
Now let's experiment :)
Mixing the right color is quite interesting, and you MUST wear protective gloves and goggles!
So what do we have?
- Rhodamine B500 - which is classified as DANGEROUS.
— Rhodamine 6G
— Fluorescein
— Bromofluorescein
— Acridine orange
— Green fluorescent dye
* Acridine orange, Bromofluorescein, Fluorescein and fluorescent green dye are not classified as hazardous substances.
— Optical brightener - according to the classification, you should work with CAUTION.
Fill test tubes and flasks with distilled water. And please use a small amount of dye! Rhodamine immediately stains your hands.
It's hard to look away from these photos... (and at the same time I constantly think about my red fingers 🙂).
Step 4: Intermediate result
And this homemade products even without UV light :)
Step 5: And here are the finished lamps…….…
Already with UV glow!!!
Brain crafts emit a pleasant light, especially in the evening, when they create an ambient atmosphere...
That's it for the "Cold Trilogy" homemade» is completed, I hope you found it interesting!
Have you decided to get aquarium fish or more exotic animals that glow in neon light? Do you want to throw a neon party at home or make a sign with neon lighting yourself? There is one common solution to all these issues - to make a neon lamp at home.
You will need it
- - hydrogen peroxide;
- – baking soda;
- – Mountain Dew drink;
- – suitable container.
In industrial conditions, neon is produced by liquefying air, which breaks down into many components, including neon and helium. This process is quite complicated. It consists of many stages and requires compliance with a number of special criteria: pressure, temperature, the use of additional substances such as nitrogen or hydrogen. At home, you can make the so-called neon liquid, the characteristics of which are identical to neon - it also shines in the darkness with a bright blue light.
In order to prepare the so-called neon liquid, prepare a half-liter bottle of Mountain Dew. You can buy this drink at your nearest large hypermarket. You will also need hydrogen peroxide and baking soda.
The carbonated drink Mountain Dew contains ingredients such as sodium benzoate, gum arabic, sodium citrate, carbon monoxide, and esters. Some of these substances are used in huge chemical laboratories.
Carefully add a quarter teaspoon of baking soda through the opening of the Mountain Dew bottle.
Pour the gas-water out of the bottle, but not one hundred percent: leave about a quarter of the volume of water.
Pour in hydrogen peroxide here. 3 bottle caps will be enough.
When creating a neon lamp at home, be careful when mixing the components.
Close the bottle with a lid and shake the mixture properly. Turn off the light and, if you measured all the ingredients correctly, the purchased mixture will shine in the darkness.
Cover simple lamps used for aquariums and terrariums, LED signs or party paraphernalia: caps, lanterns or masks with a thin layer of luminous water. Wait for the neon liquid to dry. With this consistency you can draw, for example, stars on the ceiling - it will be very beautiful.
Handmade items fill the home with special warmth and comfort. In addition, they turn out to be exclusive. We offer an overview of lamps that will completely change the atmosphere in the room, turning into the envy of friends and relatives. Moreover, they are made from everyday items that are usually thrown away.
Cardboard bags for juices or other drinks are a fairly common thing in most homes. Most often it is thrown away. But Malayan designer Edward Chu spent a lot of time cutting them into hundreds of strips and making amazing lamps from them without a drop of glue, a simple origami principle.
Yaroslav Olenev proposed making lamps from disposable plastic spoons and became the winner in the Ecology and Design category from the Future Now magazine.
No less original application I also found Natalie Simpson for ordinary wooden hangers. But they look amazing in the form of a chandelier.
Kevin Champeny must be given his due; not everyone has the strength and patience to string 14 thousand bears to get a chandelier.
Tira Hilden and Pio Diaz have their own vision of the problem of housing lighting. Their lamps make the room look like a forest. All the walls come to life and turn into trees.
A talented welder, Matt Ludwig also turned out to be an excellent designer. For the restaurant "JJ's Red Hots" he made an incredible original chandelier from the old one drum set.
Texas artists Joe O'Connell and Blessing Hancock used parts from old bicycles to create stunning lamps and hang them in a tunnel under the highway.
It will probably be difficult to find a more original chandelier than one made from a pumpkin by a Polish artist. He carves stunning patterns into the peel that never repeat.
Lampshades made from felt hats from Jeeves & Wooster.
One day, Heather Jennings saw an amazing Rhododendron chandelier in a store, but it cost more than $800. Then the designer decided that she could do no worse with her own hands. For this she needed paper cupcake liners.
11. Chandelier for the kitchen
A chandelier made from ordinary metal tetrahedral graters will look incredibly beautiful.
Vases and candy bowls made from openwork napkins are still fresh in my memory. Now it's time to knit chandeliers.
A strange option is proposed by Fansua Lego, he believes that the most The best way storing cutlery is a chandelier.
A large cloud is cut out of wood, but the rest and the switch are made of cardboard.
Several globes can make a wonderful cascading chandelier, a great way to illuminate a flight of stairs.
It is common knowledge that fish tend to be attracted to light. And when it is night and you bring light, you will see them swimming towards you. So, if you want to take advantage of this fishing technique, you may want to make this useful glowing fishing light.
The craft is made from waste, except for the waterproof LED strip and adapter. What you need to do is take a PVC pipe and attach an LED strip around it. Get a clear tube that is slightly larger than the PVC pipe you used. 
The next step is to place the LED and PVC inside the clear tube. After this, make the pipe waterproof. Place the caps on both ends and be sure to seal them with caulk. Don't forget to make a hole for the wiring. And don't forget to fill the hole with sealant to prevent water from seeping inside the tube. 
Catch more fish with this device to attract the fisherman's prey! By the way, don't forget to place some weight inside the tube. The water is denser than the tube, and LED Strip Light- both are light. The weight will allow the pipe to sink into the water.

How fish react to the light of a flashlight - underwater photography

The reaction of fish to light has been little studied, but something is known. For example, the nocturnal predator pike perch can be caught very well on a spinning rod in the dark with backlighting. In addition, in low light conditions, fish prefer baits that glow in the dark. 
Let's check the reaction of peaceful fish to light:
The white light of the lantern rather scares away the fish - the roach did not come to the illuminated area even for bait. But in contrast to white, the fish clearly liked the red color of the lantern.
Let's see how the perch behaves in the light:
Perch is a very curious fish and, unlike roach, white light does not scare it.
Illumination is a very significant factor that has a strong influence on the behavior of fish, but has not yet been sufficiently studied.
A lava lamp (made with your own hands) is a rather interesting and original item in the interior, which can also be a wonderful gift. If you don't want to spend money, be sure to try making it yourself. The construction of a lava lamp is actually not that complicated. It’s quite possible to make it right at home.
DIY temporary lava lamp
Of course, you can go to the gift shop and purchase this piece of furniture. But it's not that cheap. Let's look at how to do it lava lamp from scrap materials?
The first thing we need is a large plastic bottle from lemonade or mineral water. In general, absolutely any transparent container that closes tightly with a lid will do, but a plastic bottle is the most best option. In order to achieve the most effective result, it is better to take a container of at least 0.5 liters.
Next, you need to fill the bottle with oil three-quarters of the entire volume, and fill the remaining quarter with water and about 10 drops of food coloring. The solution should be rich in color. Now you need to add salt or any effervescent tablet, such as Alka-Seltzer or vitamin C.
Next, tightly cap the bottle and shake it. You will immediately notice how droplets of liquid begin to form, gradually connecting with each other. But this process will not occur continuously. Over time, the drops will stop forming and you will have to add more salt or effervescent tablets.
This kind of lava lamp, made with your own hands, is good because it is absolutely harmless and safe, which is important if it is to be used, including by children.
To make everything look even more impressive, install some kind of light source at the bottom of the bottle so that the beam is directed upward onto the liquid. This way, the light will illuminate these droplets, and the lava lamp will look much more impressive. You can destroy it with your own hands if the light source produces a lot of heat, which can melt the plastic.
How does a temporary lava lamp work?
What is a lava lamp made of? Its mechanism is that due to different densities, water and oil do not mix, as a result of which bubbles are formed that move freely in the liquid. And adding salt or an effervescent tablet makes the reaction even more effective.
Permanent lava lamp
How to make a lava lamp that will work constantly? It should be made by an adult, as it uses alcohol and oil, which can easily ignite when heated.
For lamps sold in stores, a special mixture of liquid waxes is used. But you can also try to achieve a similar result at home. If you try, then, in principle, it is quite possible to end up with a liquid that will be interesting to pour.
The basis of the lamp will be any glass container. In this case, you should not use plastic, as it melts easily. Mineral or baby oil will serve as those iridescent bubbles.
There is no specific amount of oil that should be added. Pour approximately, as you can add more later if it turns out to be too little. If you want a more interesting effect, you can try making a lava lamp based on oil paints, but be aware that over time the oil may separate from the dye, leaving an unsightly residue.
Now you need to add a mixture of 70 percent medical alcohol and 90 percent. They can be purchased at any pharmacy. The mixture should consist of 6 parts of 90 percent alcohol and 13 parts of 70 percent. If you follow the specified proportions, the liquid will be approximately the same density as mineral oil.
Lava Lamp Heater
The next step is to heat the mixture. First of all, you need to close the jar tightly. Next you need to make the following design: take a heat-resistant surface, for example flower pot, put it upside down. You need to place a heat source under it, and put our jar on the bottom. Over time, the lamp and the mixture inside it will heat up, the oil will expand more than the alcohol and will move up and down.
An incandescent lamp is quite suitable for creating a heating device. Its power depends on the volume, but it is better to take no more than 40 W.
