Microcontroller addict [Debraj] decided to make his own programmable sine wave generator, and was able to put it together for under $40 USD. Other than low-cost, his list of requirements was as follows: Dual sine wave output, synchronized Frequency, Amplitude, and Phase control Low harmonics under 1 MHz Scriptable via Python The heart of the […]

XYNX (pronounced ikz-sync) is being launched on Crowdsupply by Fairwaves. it is based on the success of the Octopack SDR (software-defined radio) and the feedback the firm received from the original Octopack users. It is designed for situations or use cases that involve large band of spectrum monitoring or massive MIMO system and it comes
THE ULTIMATE LOW-COST MASSIVE MIMO SDR, WITH UP TO 32×32 TRANSMIT/RECEIVE CHANNELS Continue Reading
N.B. this is new and still being tested. This sketch demonstrates several examples of single-channel filters for processing sensor data. The filter functions are purely numeric operations and not dependent on any Arduino-specific features. This supports offline testing, as they can be compiled for debugging and evaluation on a normal desktop computer. The code is

The business intelligence report on Arduino Development Kit market assist businesses and other stakeholders in effectively tackling the current and upcoming challenges in this vertical, by suggesting various approaches that can guarantee profitability over the assessment period. Besides, it comprises all other important aspects such as predominant trends, key driving forces, and opportunities that are
You can’t fake that feeling when a $4 microcontroller dev board can stand in as cutting-edge 1980s technology. Such is the case with the working transputer that [Amen] has built using a Raspberry Pi Pico. For a thorough overview of the transputer you should check out [Jenny List’s] longer article on the topic but boiled down we’re talking
RASPBERRY PI PICO USED AS A TRANSPUTER Continue Reading
Back in the early days of the musical synthesizer, some designers who wished for polyphony in their instruments would simply build multiple tone-generators for as many notes as they wished to play. [Kevin] took that same approach with his Arduino orchestra, and set about having it play the closing number from Star Wars: A New Hope. The

When we want to prototype a rover, we’ve developed a tendency to immediately reach for the 3D printer and Arduino or Raspberry Pi. It’s easy to forget the prototyping tool many of us grew up using: LEGO. The [Brick Experiment Channel] has not forgotten, and in the video after the break demonstrates how he used Lego

Kontron has launched the “SMARC-sAMX8X” module with low power I.MX8X series processor. The SMARC module runs Linux on a dual- or quad Cortex-A35 i.MX8X SoC with up to 3GB LP-DDR4, up to 64GB eMMC, dual GbE controllers, and PCIe. Kontron’s SMARC-sAMX8X delivers NXP’s mid-range i.MX8X SoC package in an 82 x 50mm SMARC 2.0 form factor,
Kontron’s SMARC-sAMX8X Features NXP i.MX8X Low Power SoC Continue Reading
Buying tools is all well and good, but it doesn’t suit the ethos of Youtube channel [Workshop From Scratch]. Building what you need is much more the go, and that’s demonstrated ably with this home-built electric workshop crane. The crane is put together in a straightforward manner using basic steelworking techniques. Plates and bars are machined

While most analog televisions come with composite video inputs on a yellow RCA jack, the feature is not universal. This problem was even more prevalent in the 1980s, and most home consoles got around the problem by instead feeding video to the television’s tuner with an RF modulator. [Manzel Seet] had just such a television
