Building A Quadcopter For Newbie
https://www.electronics-lab.com/building-quadcopter-newbie/
Drones are one of the rising technologies in the world and it became very popular that we see it in news on places that have armed conflicts, aerial photography like GoPro drones and even for customer care like the Prime Air delivery system from Amazon which is designed to get packages to customers using small […]
Introduction to I²C and SPI protocols
https://www.electronics-lab.com/introduction-i%c2%b2c-spi-protocols/
byteparadigm.com has a nice introductory article on I2C and SPI protocols: Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals. At the roots of these two popular […]
Benefits of Using A Buck-Boost Converter As A Pre-regulator For LDOs
https://www.electronics-lab.com/benefits-using-buck-boost-converter-pre-regulator-ldos/
Intersil published a new white paper titled “Preventing Subsystem Brownouts in Mobile Devices“. This white paper demonstrates the benefit of using a buck-boost converter as a pre-regulator, which leads to better overall system efficiency and enhanced battery life. Systems powered from a battery may have voltage brownout when they are subjected to a burst current […]

Intersil announces the adoption of its latest family of buck-boost switching regulators in one of Huawei’s newest smartphone. The ISL91110 buck-boost switching regulator powers the Huawei P9 smartphone’s key system peripherals providing excellent efficiency and performance. [via] Intersil’s ISL91110 buck-boost switching regulator supplies power to key system peripherals in the P9 dual-camera smartphone, using a proprietary, fully […]
Adding ADC to Microcontrollers without ADC
https://www.electronics-lab.com/adding-adc-to-microcontrollers-without-adc/
Scott @ swharden.com show us how to interface an analog signal to a microcontroller that doesn’t have an ADC. I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two […]
Analog front-end IC linearizes sensors
https://www.electronics-lab.com/analog-front-end-ic-linearizes-sensors/
Susan Nordyk @ edn.com discuss about LTC2986 which is able to digitize and linearize a combination of temperature sensors in Celsius or Fahrenheit degrees. A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines […]
MPPT Solar Charger Design based on PIC18F26J50
https://www.electronics-lab.com/mppt-solar-charger-design-based-pic18f26j50/
Lukas Fässler shares his Maximum Point Tracker Solar Charger Design based on PIC18F26J50: At the core of the design is a PIC18F26J50 in a 28 pin SOIC package. It’s capable of running at down to 2.15 volts and consumes extremely little power when running at lower clock speeds. And apart from that it features USB […]
CO2, temperature and humidity monitor
https://www.electronics-lab.com/co2-temperature-humidity-monitor/
An open source CO2 monitoring project from Roving Dynamics: The project described below uses a MH-Z16 or MH-Z19 CO2 sensor and a DHT-22 (or DHT-11 if less accuracy is required) to measure the Temperature and Humidity. It has a 4 line by 20 character LCD Display to show the current readings and status, a warning alarm […]
Ultrasonic Anemometer Project Progress
https://www.electronics-lab.com/ultrasonic-anemometer-project-progress/
Lukas Fässler discuss about his anemometer project progress and what tests he has performed so far. In the mean time I managed to do some rudimentary testing and now feel confident to take orders. These tests concern the hardware only. What I said last time about the state of the software still applies. But let […]
