I have an MFJ analyzer, actually just back from the shop, but I’ve built quite a few projects for analyzing antennas. None agree 100% with each other, but all are functionally adequate.

[Eunjae] is using an Arduino Nano, a 128×64 OLED screen, and a battery inside of a rugged waterproof case. He also added an ADS1115 16 Bit DAC between the oxygen sensor and the Arduino for fast ...

Arduino files for the Rainbowduino based spectrum analyzer I first got the Seeed Studio 3D LED Cube, which included a Rainbowduino as it's controller. It looked like a lot of fun so I got the 8x8 RGB ...

Arduino may be known for revolutionizing open source hardware platforms, but this week it enters the 3D printer market with the small and affordable Materia 101. Produced in partnership with ...

Arduino has been used to build just about anything that can be imagined — from VR headsets, to COVID-19 masks, to lie detectors, coffee roasters, STEAM kits and everything in between. To learn how to ...

The Arduino has long since proven itself to be one of the biggest boons to DIY heads since the soldering iron, but that doesn't mean it's not still able to impress, as amply demonstrated by this ...

Arduino, maker of the open source hardware platform of the same name, is teaming up with a startup called Sharebot to sell a 3D printer for about $1,000.. Announced today, Materia 101 will be ...

This Arduino sketch implements a SUMP protocol compatible logic analyzer. This implementation is compatible with the standard SUMP client as well as an alternative OLS client. More recently support ...

It features 25 3D printed parts, 16 servo motors, 3 motor controllers, and an Arduino Due brain. The next phases of the project will add a second arm and eventually facial expressions via a ...

Abstract: In this paper a new, low cost and efficient PV analyzer has been designed using the Arduino open source electronic platform for remote areas of developing countries. The designed analyzer is ...

A fully fledged spectrum analyzer on a basic Arduino board? It is possible when the software is tailored to the available processing power. A standard Arduino can be turned into an AC line (‘mains’) ...
