In this video educ8s.tv shows us how to build an Arduino Robot that can avoid obstacles: The robot that we are going to build today is moving around and it can detect obstacles and avoid them. It uses a supersonic distance sensor in order to measure the distance from its front side. When it […]
PV cell string optimizer boosts solar panel output up to 30%
https://www.electronics-lab.com/pv-cell-string-optimizer-boosts-solar-panel-output-30/
Maxim presents its Cell-String Optimizer as the first IC to perform MPPT (maximum power point tracking) at low level in a panel; it allows photovoltaic (PV) panels to harvest significantly more energy and simplifies design complexity for solar installation projects. by Graham Prophet @ edn-europe.com Maxim’s cell-string optimizers are highly integrated DC-DC converters that replace […]
LTC7851 – Quad Output, Multiphase Step-Down Voltage Mode DC/DC Controller with Accurate Current Sharing
https://www.electronics-lab.com/ltc7851-quad-output-multiphase-step-voltage-mode-dcdc-controller-accurate-current-sharing/
The LTC7851 is a quad output multiphase synchronous step-down DC/DC controller with accurate current sharing between phases and differential output voltage sensing. This controller works in conjunction with external power train devices such as DrMOS and power blocks as well as discrete N-channel MOSFETs and associated gate drivers, enabling flexible design configurations. Up to 8 […]

The MAX6954 is a versatile display driver, capable of controlling a mix of discrete, 7-segment, 14-segment, and 16-segment LED displays […]
Cheap Arduino Serial Terminal
https://www.electronics-lab.com/cheap-arduino-serial-terminal/
Peter Scargill writes, As it happens I’m experimenting on a 1284 chip which while being Arduino-compatible kind of, it does have another serial port, so without disconnecting my FTDI – I hooked up the second serial port to the home control serial and fired the DEBUG command at the latter. As you can see on […]
Using A Bench Power Supply To Charge Lithium Ion Batteries
https://www.electronics-lab.com/using-bench-power-supply-charge-lithium-ion-batteries/
David Jones has another useful video tutorial about how to safely charge Lithium Ion and Lithium Polymer batteries with a bench power supply. The purpose of this tutorial is to learn how to use your lab power supply to charge your Lithium Ion battery when you don’t have a special charger circuit to do so. […]

Tools for the Electronics Hobbyist Part 1- Graphical Components Tester
https://www.electronics-lab.com/tools-electronics-hobbyist-part-1-graphical-components-tester/
When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpress and Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because […]
