Guangdong-based electronics manufacturer, MeLe has been in the news a couple of times over the years for a number of their tiny but powerful intel mini processors-based desktop PCs. The company recently shared the beginning of sales of one of their latest creations; the MeLe Quieter 2, a...

Linear voltage regulators are used to maintaining a steady output voltage. They are step-down converters where the input voltage is always higher than the output voltage. The output voltage can be adjusted by external resistors. 78xx series is a very popular linear voltage regulator...

We saw BOMIST first in late 2017. With a new version re-written from scratch being released by the end of 2020, we are revisiting it now. Although at first sight, we can spot quite a few similarities in regards to the UI, there is now more features (and very useful ones), better user...

DFRobot Gravity: Speech Synthesis Module converts lines of code into speech and supports both English and Chinese languages. This module operates from 3.3V to 5V power supply range, -40°C to 85°C operating temperature range, <50mA operating current, and 5%RH to 85%RH operating...

Arduino recently announced their Arduino Nano RP2040 Connect board, which is a port of the latest Raspberry Pi Pico. Along with it, they’ve also decided to port the Arduino core, bringing the Arduino IDE, libraries, and more to the Raspberry Pi Pico. Even though the official port is...

This is a precision, low power, and easy-to-use oscillator that provides multiphase outputs. The output frequency of the project is set to 250Khz, with 40% spread spectrum. The oscillator frequency can be set by resistor R1, and the spread spectrum can be changed using R3. The master...

This SLA Battery charger project is the right choice if you want to obtain maximum battery service life and capacity, along with acceptable recharge time and economy, constant current, constant voltage, and even charge a deeply discharged battery. The project contains all the necessary...

We saw Pokit Pro’s second Kickstarter campaign in late 2019. It was a crowdfunding project with AU$30,000 and counting in the November end of 2019. The company’s current press release in 2021 says Pokit PRO has raised over AU$1.66 million from nearly 10,000 backers. Pokit...
