Lithium-ion vs. Lithium-polymer Batteries
Posted on: 01 Mar 2024
Introduction As the vital energy sources driving technology innovation, Lithium-ion (Li-ion) and Lithium-polymer (Li-po) batteries have emerged as leading power solutions across electronics – from laptops, smartphones, and electric vehicles to drones. Despite harnessing lithium, Li-ion and Li-po batteries feature unique attributes, tailoring them to specific applications and uses yet universally enabling devices to unleash […]

You will be pleased to know that a new microcontroller board has been launched this week in the form of the Arduino Nano 33 BLE Rev2, priced at €22,80. The latest addition to the Arduino Nano […]
RESTORING STARLINK’S MISSING ETHERNET PORTS
Posted on: 01 Mar 2024
Internet connectivity in remote areas can be a challenge, but recently SpaceX’s Starlink has emerged as a viable solution for many spots on the globe — including the Ukrainian frontlines. Unfortunately, in 2021 Starlink released a new version of their hardware, cost-optimized to the point of losing some nice features such as the built-in Ethernet […]
DIETPI VERSION 9.1: NOW WITH RASPBERRY PI 5 SUPPORT AND MORE
Posted on: 29 Feb 2024
DietPi recently released version 9.1, which among other changes includes new images for the Raspberry Pi 5, Radxa Rock 4 SE and NanoPi R5S/R5C & 6. The Radxa Rock 4 SE image was necessary because the Rock 4’s RK3399 SoC is subtly different from the RK3399-T’s SoC in terms of memory support, which prevents a Rock 4 image […]

ESP32 OSCILLOSCOPE SKIPS SCREEN FOR THE BROWSER
Posted on: 27 Feb 2024
An oscilloscope can be an expensive piece of equipment, but not every measurement needs four channels and gigahertz sampling rates. For plenty of home labs, old oscilloscopes with CRTs can be found on the used marketplace for a song that are still more than capable of getting the job done, but even these can be […]
Remote Control: Interacting with an Arduino via Web Interface
Posted on: 25 Feb 2024
Upon acquiring my initial Arduino board, my immediate aspiration was to administer it through a web interface. However, lacking an Ethernet shield initially, I deferred the idea. Recently, spurred by curiosity, I procured a shield from Amazon to explore the possibilities. The foremost step entailed drafting a basic sketch capable of rendering a web page […]
