If like me you enjoy using the range of Arduino development boards to create a wide variety of different projects. 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 […]

Most of us are familiar with the Arduino Uno, a starting place for electronics projects since 2010. But what if the Arduino Uno was released in 1980? You’d probably get something like [ElectroBoy]’s 8051-based Arduino Uno. The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52.

In November 2018, Hrdkernel announced the ODROID H2 as a “new generation of single-board computers.” However, despite its success, they could not ship enough of them to satisfy the demand due to the Intel Gemini Lake J4105 CPU supply shortage. Due to the shortage of the ODROID H2, the Odriod-H2+ was introduced, which has a slightly faster CPU, and will ship in
We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a silicon wafer somehow, and since any sufficiently advanced technology is indistinguishable from magic, they miraculously create a large part of modern society. Even most computers

There is an episode of Ren and Stimpy with a big red “history eraser’ button that must not be pressed. Of course, who can resist the temptation of pressing the unpressable button? The same goes for development boards. If there is a button on there, you want to read it in your code, right? The Raspberry Pi
BUTTON, BUTTON, WHO’S GOT THE (PICO) BUTTON? Continue Reading
One of the things missing from the “classic” Arduino experience is debugging. That’s a shame, too, because the chips used have that capability. However, the latest IDE has the ability to work with external debuggers and if you want to get started with a classic ATMega Arduino, [deqing] shows you how to get started with
THIS ARDUINO DEBUGGER USES THE CH552 Continue Reading
Back in the 486 days, it was common to see a “Turbo” button on the front panel of many PCs, which was used to toggle between the CPU’s maximum speed and a slower clock rate that was sometimes necessary for compatibility with older software. Usually an LED would light up to show you were running

There was a point in time, excruciatingly brief, in which desktop computers often had a large “TURBO” button on their front panel. Some even featured an LED display that would indicate the current CPU frequency, providing visual conformation that your machine had leaped to a blistering 66 MHz. The 486 that [someyob] is restoring had

When you think of an MMU — a memory management unit — you probably think of a modern 32-bit computer. But [Jeff Truck] has a surprise. His new RCA 1802 computer has bank switching, allowing the plucky little processor to address 256K of RAM. This isn’t just the usual bank-switching design, either. The machine has several unique

Axiomtek – a world-renowned leader relentlessly devoted in the research, development and manufacture of series of innovative and reliable industrial computer products of high efficiency – is pleased to introduce the CAPA13R, a high-performance 3.5” embedded board with quad displays. The CAPA13R is powered by the onboard AMD RYZEN™ Embedded V1807B/V1605B processor with AMD Radeon™ RX
