What’s The Difference Between A Stepper Motor And A Brushed DC Motor?

There have been several different types of electric motors in use for decades, and all of them drive mechanisms or something similar. What sets stepper motors apart from brushed DC motors? Brushed DC motors are designed to rotate their shafts continuously and are used in applications where they are not required to make precise movements…

Arduino and ESP32 microcontroller kits

What’s The Difference Between An ESP32 And An Arduino?

There are several different Arduino products on the market, as well as several ESP32 products. The very first thing we should do here is break down what these two devices really are. To start: An ESP32 is a System-On-A-Chip (SoC). What’s An Arduino? Arduino refers to a platform that runs on Atmel microcontrollers (MCUs). An…

Raspberry Pi Power Requirements: What Size Battery Does A Raspberry Pi Need?

The power requirements of a Raspberry Pi computer are dependent on the model and usage. However, you must size your power source to accommodate the Raspberry Pi’s highest possible power usage. Afterwards, you can worry about how long your Raspberry Pi battery will last per charge. The use of a 5 Volt lithium-ion battery pack…

Thermaltake Luna 12 Review: A Quiet 120mm Case Fan

The Thermaltake Luna 12 is a 120mm (4.7-inch) axial case fan for PCs. It is twice the size of many of the case fans you’ll see in a typical microATX PC. However, that results in a greater airflow-to-noise ratio (or greater airflow-to-audible noise ratio). At its maximum speed, the Luna 12’s noise level was barely…

What Are Supercapacitors?

Supercapacitors have been mentioned from time to time due to their uses in some hybrid and electric vehicles, as well as other devices, but what are they? A supercapacitor is an electric double-layer capacitor. It differs from a conventional capacitor in that it offers a significantly higher energy density. As is the case with conventional…

TI Introduces Crystal-less MCU Using BAW

The crystal oscillator is a longstanding concept that employs a physical oscillator for clocking to facilitate accurate timing in electronics. These oscillators have been driving CPU clocks, as well as low frequency (and low power) non-CPU clocks in devices that need to be able to use their peripherals (for example: analog to digital converters) while…

Comparing The Raspberry Pi 3A+ Vs The 3B+: The Most Important Differences

The Raspberry Pi single board computers (SBC) have been released over the years with incremented model numbers such as the Pi 1, Pi 2 B, 3, 3B+, etc. Now the Raspberry Pi foundation has been updating older models like the A series, as they offer benefits such as a smaller form factor (they can fit…
