Electronics has entered most aspects of everyday life from the home right through to the office, business scienftific research and much more. In this section of Electronics Notes we aim to look at some of these items that may not be covered elsewhere and look at their technology and how they work.Power & power supplies, chargers, etcPower management is a key area of electronic equipment these days: everything from charging to the management of battery life and when to recharge batteriesAudio visualHome gadgets
One of the problems with home built electronic projects is in obtaining a really good professional looking finish. One way to help achieve this is to use one of the many ready painted cases that are available from the electronics component stockists.While ready painted cases may look very good when bought, holes need to be drilled and other metalwork may need to be done to enable the front panel and rear panels to take the controls and connectors.

3GPP overview includes:What is 3GPPStandards/ Releases3GPP groups3GPP, 3rd Generation Partnership Project is an industry collaboration that manages the standards for the on-going mobile communications systems.The name implies that it was an organisation focussed in 3G UMTS technology, and this was how it started.
Serial data transmission standards including RS232, RS422, RS423, and RS485 were widely used for many data links, proving effective connectivity for the day. Although not nearly as widely used today, they can still be found in some areas.Serial data transmission links used cables with a variety of different functions to enable data to be sent reliably between two equipments.
Connectivity in both wired and wireless forms is part of everyday life. From wired and fibre broadband to mobile communications - 2G, 3G, 4G and 5G, Wi-Fi, Bluetooth and many other wireless technologies through to standards like Ethernet, USB and many others. Wi-Fi is particularly important as demonstrated by the number of Wi-Fi routers, Wi-Fi repeaters and the like that are available for sale.
