Components:

1. Ferric chloride 200-1000 grams.

2. Capacity depending on the size of the board (preferably not deep).

3. Foil textolite is double-sided or plain, depending on what kind of board you will make.

4. Nitro-lacquer or nitro-paint 50 grams.

5. Thinner 646 or acetone.

6. A thin needle from a syringe.

7. Microdrill (motor 12-40 W with fasteners for a drill), drills 0.8mm, if necessary, larger.

Production:

1. Ferric chloride is diluted in a jar of water (water should be at a temperature of 50-65 degrees) at a concentration of 500g ferric chloride and brought to one liter with water. Stir until completely dissolved and the solution is ready.

2. Next, you need to prepare a varnish or paint, pour it into the cap from a plastic bottle by half, dilute it with acetone or a solvent so that you can fill the needle (you need to suck it halfway into the needle with your lips) with paint, you can draw on textolite, liquid for thin thicker for a thick needle.

3. Then you need to draw a drawing with a pen on the textolite and drill holes in the right places.

4. Draw now with a needle along the lines, let it dry for 15 minutes.

5. You settle the textolite into a solution (45 ... 60 degrees) of a filled container and after 15-40 minutes it turns out that the unnecessary foil has dissolved, only tracks remain and no work is needed to cut out the tracks.

6. And finally, you need to wipe off the varnish with acetone.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

New technology will increase the range of electric vehicles 16.03.2022

Scientists at the University of Central Florida have developed a composite material that expands the potential of lithium batteries for electric vehicles. The authors call their solution a "power suit" for batteries. With this technology, batteries in electric vehicles will be less prone to fire and increase the range of cars by at least 25%. For example, electric cars with a range of 320 km will be able to travel an additional 80 km, but their weight will not change.

The hybrid device is based on a new generation material with an energy storage function. To construct it, engineers created positively and negatively charged layers of carbon fiber. The latter were stacked in an alternating order - thus, the scientists assembled a durable energy-storing composite. In addition, the new material received strips of carbon graphene with several types of metal oxides. After a series of experiments, the scientists found the optimal composition and created a "supercapacitor battery".

Special sheets of graphene attached to layers of carbon fiber provided an increased ability for the material to store a charge. At the same time, metal oxides deposited on the attached electrodes increased the voltage and provided a high energy density. At the same time, the life cycle of the finished battery was not affected - the resource of charge-discharge cycles of their battery is 10 times longer than that of commercial batteries for electric vehicles.

Among the additional advantages of the invention, scientists have identified non-toxicity and incombustibility. Thanks to its construction, which uses multiple layers of carbon fiber, the material has the necessary toughness and strength to withstand a car crash. Even in the event of a serious accident, a new battery will only deform, but will not catch fire. The system also works as a supercapacitor, so it can increase the power of electric cars - for example, it will take just 0 seconds to accelerate from 100 to 3 km / h.

The characteristics of the new reinforced battery will depend on the type of basic design. However, scientists are already promising an additional 25% range for electric vehicles, as well as a significant reduction in the weight of batteries. The charging speed of electric cars will also be increased.
