Scalar Network Analyser

DuWayne and I have been corresponding for a couple of years, sharing mutual interests. I was pleased to be able to give his work a shout in both the printed and  'spoken' version of my talk at this year's Four Days in May event in Dayton and - more importantly - to catch up with the man in person for a quick eyeball QSO. I also got a PCB for SNA Jr, which has been sitting on the bench for months - until las ...

WiFi enabled Motors

Revolutionizing Motor Control If you’re a tinkerer or creator, motors are an essential part of your many projects. We are accustomed to controlling them with Arduino boards and creating a mess just to solve a simple problem. Everyone has an idea that needs a motor, but not everyone appreciates the effort required to get one up and running. We are OpenMYR, and we are changing the way you control motors. We'v ...

Cheap homemade 30 MHz – 6 GHz vector network analyzer

Introduction Vector network analyzer (VNA) are used to measure scattering parameters of high frequency circuits. When frequency is high enough the reflections of the waves start to matter and distributed effects need to be taken into account. VNA can be used to analyze reflection and transmission coefficients of circuits at high frequencies. For example ideally antenna would radiate all the energy it gets, ...

Wi-fi browser controlled servomotors

This instructable shows how to control some servomotors remotely in a wi-fi network, using an ordinary internet browser (Firefox, for instance). This might be used in several applications: toys, robots, drones, camera pan/tilt, etc. The motors were attached to an Arduino Uno, which connects the wi-fi network through a ESP-8266 module. The control interface was designed with HTML and jQuery. Miguel's tutoria ...

The Nerd

Help keep your IoT pet alive via the Internet! Story If you had an IoT pet, what would it eat? WiFi SSIDs, of course! The Nerd is a wireless electronic pet that survives by collecting WiFi SSIDs along with some rest and sunlight. In order for it to thrive, you must balance offline and online mode with light and darkness to ensure that it has a proper daily eat-sleep-Nerd routine. If it is out of WiFi for to ...

Troubleshooting a 32kHz Crystal Oscillator

For Project Whack a Mole I need a 32.768kHz crystal oscillator. I found this circuits on the Interwebs and gave it a try: It wouldn’t go. I messed about changing component values for while, then decided to actually try to understand the circuit. Now for an oscillator to work, we need an amplifier with a gain of greater than 1, and a phase shift of 360 degrees to get positive feedback. The circuit above is a ...

Time Stamp from Web Server

INTRODUCTION In this project, we will learn the basics of Transmission Control Protocol (TCP) and how to communicate to a webserver over TCP. We will request and receive packets from the Google web server using the above communication protocol. The 4Duino display is used to print the status of the connection and the received information for debugging purposes. Transfer of Data over Internet The 2 most commo ...

Monocle: View & Control IP Cameras with Alexa & Arduino

Monocle enables Alexa devices such as Echo Show/Spot & FireTV to view your network IP cameras & control them with a wireless PTZ controller. Story Amazon Alexa® (at least at the time of this writing) does not inherently support any direct integration with local/private network cameras running securely inside your network. Instead Alexa focuses on providing an infrastructure for third-party camera ma ...

Intelligent Buggy featuring 4Duino-24

4Duino Intelligent Buggy project demonstrate how does uCAM-II works. This project also utilized two 4duino communicating using Server-Client architecture over TCP. It also uses a buggy car which carry the 4duino server and uCAM-II. By using built-in ESP8266, 4duino client sends a request to 4duino server to move the buggy and capture photo via wireless communication. Server-Client architecture is a network ...
