The Indonesian Directorate General of Customs and Excise just announced that it has started using a  blockchain  based shipping platform. Blockchain pioneer, Bitcoin, has hit $9682 in value per coin. It is estimated that the number of cryptocurrencies by the close of 2019 was approximately 2957. Blockchain is rising fast. Its adoption has gone beyond cryptocurrencies. Blockchain has certainly taken off, its limits can only be left to the test of time A gentle introduction to blockchain On its most fundamental level, blockchain is basically just a series of blocks, but not in the classical sense. Saying these words “block” and “chain” in this setting, we are simply talking about the electronic information block contained in the public registry-chain. The word  blockchain   technology   simply refers to an open, cryptographically secure, publicly available system that enables us to safely transfer assets of valuation units using public-key encryption a...

The zeal with which 5G is being received is evidence of the growing interest in millimeter-wave frequencies across the globe. Communication frequencies are growing every passing day hence the need for cables and  connectors  high frequency to move these high-frequency signals from one point to another. To meet this growing need for high-frequency transmission, terminating connectors that provide the standard RF architectures for the cables must meet the rigorous mechanical and electrical specifications. They are useful when linking coaxial modules within a system or when making a hookup between a device under test (DUT) and a test device. The rapid development of services like paging and mobile phones has resulted in increased demand for coaxial cables. The rapid evolution and complexity of these systems have demanded progressively rigorous electrical and mechanical specifications depending on the suitable placement of materials, design and development and process techno...

The first model of  Raspberry Pi  was developed in the UK for the promotion of teaching basic computer science in schools. It has size that of a credit card and can be plugged into computer monitor or TV, and has the capability of doing everything a Desktop PC can do. Let’s have a look into 21 great  uses of Raspberry Pi . 1.  Building a Robot with Raspberry Pi If Raspberry Pi could have a second name, it would have definitely been a Robot. Raspberry Pi can be used as the main brain in drones and Remote-Controlled Planes. A robotic arm can also be made with it which can hand over to you a cup of Coffee. 2.  Hosting a Website A  Raspberry Pi  can be used as a web server. You can host your own personal website or a Professional one by installing the right software and libraries. The advantage is that it requires less power and can be used on local network instead of the internet. 3.  Forecasting Weather Temperature and air humidity can ...

For years,  DC Fans   have always been the go-to remedy in an architect’s thermal control tool chest, offering effective airflow for products that require heat elimination from a few watts to the several hundred watts. It is vital to harmonize the ventilation needs of the framework with the flow of air features of the fan to guarantee that the adequate ventilator is chosen.  The proper fan can be chosen with expertise of the necessary airflow and pressure to provide sufficient cooling. Where a single fan may not be adequate, operating fans in parallel or in series offers designers with additional features to satisfy the heat specifications of their implementation. Airflow Parameters There are a few specifications which are crucial to understand in terms of airflow and heat transfer before a fan can be stipulated for a particular function. Moving air is beneficial in cooling artifacts by thermal conduction from the object and then redistributing that heat o...
