Miniature 30W Charger

21.04.2021

Since the introduction of gallium nitride in chargers, there have been many pocket-sized adapters up to 120W on the market. Presented on the charger AOHi Magcube 30W is the smallest adapter of this power.

This charger weighs 42 grams and measures 28 x 28 x 32mm. According to the manufacturer, this charger is approximately equal to a 5-watt Apple power supply.

The AOHi Magcube 30W features a USB-C connector and also has a built-in LED indicator that glows amber when your device is fast charging, turns blue when it's charging at standard speed, and turns green when it's charging continuously.

This adapter allows you to charge your iPhone 12 at 20W and also supports various charging protocols such as Power Delivery 2.0 and 3.0, PPS, Apple 2.4, BC 1.2 and Quick Charge 2.0, 3.0. and 4.0+. The adapter is compatible with Nintendo Switch and even has a charging mode for small devices such as headphones, smartwatches and fitness trackers.

The price of the device is $30.

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. ... >>

Electronic helmet for truck drivers 14.04.2024

Road safety, especially for drivers of heavy construction equipment, is a top priority for engineers and scientists. In light of this, the German Fraunhofer Institute for Structural Strength and System Reliability has introduced a new product - an electronic helmet, which is designed to protect drivers from serious injury when driving construction vehicles. A new electronic helmet developed by a team of engineers from the Fraunhofer Institute opens up new perspectives for the safety of truck and construction equipment drivers. The device is capable of monitoring the level of shaking in the car cabin and warning the driver of possible danger. The basis of the helmet's operation is a built-in piezoelectric sensor, which generates electricity during physical deformation. This mechanism allows the device to respond to intense vibrations typical of construction equipment. When the level of deformation exceeds safe values, an alarm system is activated on the helmet, ... >>

Antivitamins instead of antibiotics 13.04.2024

The problem of bacterial resistance to antibiotics is becoming increasingly serious, posing a threat to the effective treatment of infections. In light of this, researchers are looking for new ways to combat superbugs. One of the promising directions is the use of antivitamins that can have an antibacterial effect. Antivitamins, although known as the opposite of vitamins, have proven to be a promising tool in the fight against bacterial antibiotic resistance. A study conducted by scientists from the University of Göttingen in Germany confirmed their potential in creating new drugs to combat dangerous infections. With the rise of antibiotic-resistant superbugs, there is a need to find alternative treatments. Antivitamins are molecules similar to vitamins, but capable of inhibiting bacterial activity without harm to the human body. At the moment, science knows only three antivitamins: rose ... >>

Driver IC for automotive electronic throttle control systems 18.07.2015

Toshiba Electronics Europe has introduced a new miniature DC brushed motor driver IC. The new TB9051FTG is intended primarily for use in automotive engine management systems (electronic throttle and valve timing), but can also be used to control on-board systems with an operating current of up to 5 A, such as rear-view mirrors and trunk locks.

The TB9051FTG is a single-channel H-bridge supporting two power supplies (VBAT and VCC). In addition to forward, reverse and brake functions, this IC also has PWM control and current limit control functions, and can be applied to high-side current monitoring, diagnostic outputs, and power-on reset. The new device comes in a compact 28mm x 6mm P-QFN6 package suitable for mounting on small circuit boards.

The TB9051FTG driver circuits use DMOS transistors and state-of-the-art manufacturing processes provide an ultra-low on-resistance of 0,34 ohms (high side + low side, max). The IS also uses various built-in fault detection functions to implement functional safety. Among them are circuits for detecting overcurrent, overheating, low and high voltage. The operating voltage ranges of the TB9051FTG are: VBAT from 4,5 to 28 V, VCC from 4,5 to 5,5 V, Toshiba said.

The company has conducted a series of TB9051FTG IC failure simulation tests on various systems and provides customers with documentation for design and safety analysis. The delivery of evaluation samples will begin in September 2015, and the start of mass production is scheduled for October 2016.
