We recommend reading in our Free Technical Library:

Radio station on 144 MHz



Section Civil radio communications. Not an unimportant question: how to program the processor and, most importantly, with what? Of course, I mean the microcontroller. The following will concern only the AVR family from Atmel, although it also produces other microcontrollers (such as the 8051 Intel, which only have all sorts of DACs and other devices on the chip or the most powerful 16/32-bit RISC processors in the FPGA version, which are unrealistic to solder at home) ... >>

Voltage converter for cell phone chargers, 12/300 volts



Section Voltage converters, rectifiers, inverters. The article proposes a simple voltage converter for pulse chargers (chargers) of cell phones. Its use makes it possible to charge cell phone batteries from a 12 V DC source, for example, from a car's on-board network. During a long trip by car or a countryside family vacation in nature, the problem of charging a cell phone battery often arises. ... >>

Switch-on signaling device in the mains plug



Section Power supply. Any operating electrical appliance powered by 220 V is a potential source of danger. In case of improper operation, a malfunction or an accident in the mains, it can cause a fire, which in the age of plastic and an abundance of a wide variety of finishing materials can cause enormous damage in a matter of minutes. From time to time, even very attentive and responsible people forget, for example, about the included iron, electric kettle, electric stove, washing machine, electric oven. Radio amateurs are no exception, who can forget about the included soldering iron, charger, measuring device. To reduce the likelihood that the appliance will work unnecessarily for a long time, it is proposed to make a simple signaling device that periodically beeps to remind you that the appliance is plugged in. ... >>

Using Apple Vision Pro during surgery 16.03.2024

The medical team at Cromwell Hospital in London used Apple Vision Pro for the first time during two spinal surgeries. This event confirms the headset's potential as a medical tool that will change the way surgical practice is performed. Although the doctors themselves did not use Vision Pro, the operating room nurse worked with virtual reality using glasses while preparing and performing procedures. The headset made it possible to view virtual screens in the operating room, select instruments and monitor the progress of the operation. Software developed by eXeX, a company that specializes in creating artificial intelligence-based applications for surgery, has significantly improved the patient care process. Using Apple Vision Pro opens up new opportunities for developing healthcare applications such as clinical education, surgical planning, training and medical imaging. Implementation of Apple Vision Pro in the medical industry ... >>

Carbon storage in the North Sea 16.03.2024

Norwegian Energy Minister Terje Åsland has announced the launch of the Longship project, which aims to create a central carbon dioxide storage facility in the North Sea. This ambitious project is valued at $2,6 billion and aims to apply CCS (carbon capture and storage) technology to mitigate the impact of climate change. Norway already has experience in CCS, thanks to the successful Sleipner and Snohvit projects, and is now looking to increase the amount of carbon sealed beneath the seabed. Longship's plan calls for capacity to capture and store 1,5 million tons of carbon annually over 25 years. Despite the positive outlook, there are concerns about the long-term consequences of such storage. However, proponents of the project argue that offshore carbon storage has a number of advantages, including minimal environmental impact. The Longship project is carried out with the participation of Equinor, Shell and TotalEnergies through the joint venture Northern Li ... >>

Mini-organs grown from human amniotic fluid 15.03.2024

An international team of scientists led by Professor Fan Xiulin from Zhejiang University has developed a unique method of growing mini-organs from cells found in human amniotic fluid. This significant medical breakthrough could lead to improved diagnosis and treatment of congenital diseases. The organoids, which are three-dimensional cellular structures that mimic organs on a smaller scale, were grown from lung, kidney and small intestine cells found in amniotic fluid. This method opens up new possibilities for studying various fetal conditions and may be the key to early diagnosis and treatment of birth defects. Although no treatment has yet been attempted, the scientists hope their research will help combat the serious congenital diseases that affect millions of newborns each year. This breakthrough could change medical interventions by making it possible to diagnose and treat congenital diseases. ... >>

Childbirth in space 20.11.2018

Spacelife Origin employees want to realize the idea of ​​having a baby in orbit by 2024. To date, women are being searched who are ready to help science.

According to the head of Spacelife Origin, Casey Mulder, in order to become an "interplanetary species" humanity needs to learn how to give birth in space. The first stage will be the launch of the capsule, which is also called the "space incubator". Fertilization should take place in it, then the incubator will return back to Earth, and the authors can proceed to the next step. There will be a search for women who will agree to carry these embryos, and when the time comes, one of them will fly into space to give birth.

If everything goes well, then a full-fledged birth is planned already in 2024. Only a woman who has good health and stamina will recover into orbit to give birth. She will be accompanied by a team of trained obstetricians. They will provide the mother of the "cosmic child" with quality childbirth without risk to the health of both.
