As a part of the Microchip Get Launched design competition, Virginia-based Great Big Factory, an electronic device manufacturer, has designed SMT parts counter that runs on a CR2032 coin cell– BeanCounter. Yet to be launched for crowdfunding on CrowdSupply, the manufacturer has provided enough details to decide if this is a product you would want […]

Battery on a motherboard – Choosing the right one


https://www.electronics-lab.com/battery-on-a-motherboard-choosing-the-right-one/

All motherboards are equipped with a CMOS battery. In the past, it was necessary to maintain the operation of the CMOS memory, which was responsible for storing BIOS data and other parameters of a personal computer. Previously, BIOS settings were stored in CMOS memory which was powered by an independent power source like batteries. With […]

Universal remote controls are very cool devices that can be programmed to operate various brands of one or more types of electronic devices. You can point the universal remote control to any device and control it with buttons available on the remote. Low-end remote controls can control few appliances of the same brand, but high-end […]

OpenRPNCalc: Custom scientific RPN calculator based on STM32


https://www.electronics-lab.com/openrpncalc-custom-scientific-rpn-calculator-based-on-stm32/

Reverse Polish Notation (RPN) is a popular method for representing mathematical expressions. In this notation, the operator symbol comes after the operands in contrast to the Polish notation, where the operators are placed preceding the operands. For example, the Polish notation for the addition of 2 and 5 is 2+5, while in reverse Polish notation, […]
