Antenna Analyser Project. This VSWR analyser looked interesting from K6BEZ.

Antenna Analyser Project

Certainly simple and low cost and probably just the thing to test the multiband SOTA antennas that I have been putting together lately. Antenna Analyzer. Software Control is done by serial comunications.

The default Baud-rate is 57600, 8 bit, 1 stop bit, no handshake. Syntax: Make 1. Make. How to build a PMA permanent magnet alternator generator for wind turb – WindGenKits. We have created a series of videos to demonstrate the process: Step 1: Winding the coils and connecting them together.

Step 2: Casting the coils in resin to make the stator. Step 3: Building the Rotors This layout provides a great starting point for designing your own PMA.

When you’re an Architect

I absolutely love being an Architect. I’ve been an Architect almost as long as I haven’t been an Architect (don’t try to do the math, please) and at this point I really can’t imagine doing anything else. Actually, I can’t imagine “being” anything else. It’s become more than a profession. It’s become part of the definition of who I am. Calibrated Background Noise Generators. Microcontroller.

Geiger Counter - Radiation Sensor Board for Arduino and Raspberry Pi. Difficulty Level: Beginner - Tutorial Index Manifesto Go to index The main finality of the Radiation Sensor Board for Arduino and Raspberry Pi is to help people in Japan to measure the levels of radiation in their everyday life after the unfortunate earthquake and tsunami struck Japan in March 2011 and cause the nuclear radiation leakages in Fukushima.

Geiger Counter - Radiation Sensor Board for Arduino and Raspberry Pi

We want to give the chance to measure by themselves this levels instead of trusting in the general advises which are being broadcasted. Arduino. Learn how to use the Arduino voltage sensor module. Feel Extreme Workbench Envy After Seeing The Tempel. For those of us with space to spare, our workbenches tend to sprawl.

Feel Extreme Workbench Envy After Seeing The Tempel

The others who are more space limited will certainly feel envy at [Love Hultén]’s beautiful Tempel workbench. The workbench appears at first to be a modern interpretation of a secretary’s desk. There are some subtle hints that it is no ordinary piece of furniture. Raspberry Pi. High-Power Control: Arduino + N-Channel MOSFET. Eventually you are going to find yourself holding a 12v solenoid, motor, or light and wondering “How the heck am I supposed to control this from my Arduino?”

Getting Started with PlatformIO and ESP8266 NodeMcu. The Arduino editor, while functional, has never been a pinnacle of productivity and usability.

Getting Started with PlatformIO and ESP8266 NodeMcu

PlatformIO has recently been released to bring some much needed improvements to the ecosystem. The IDE is built on top of GitHub's Atom text editor, which provides an excellent extensibility model that the Arduino IDE was sorely missing. Raspberry Pi. Arduino UNO Tutorial 6 - Rotary Encoder. Arduino UNO Tutorial 6 - Rotary Encoder We have written a tutorial for Rotary Encoders using a Microchip microcontroller but now would be a good time to make an Arduino UNO version.

Arduino UNO Tutorial 6 - Rotary Encoder

With a rotary encoder we have two square wave outputs (A and B) which are 90 degrees out of phase with each other. The number of pulses or steps generated per complete turn varies. Getting Started With PCB. Table of Contents This document is a manual for PCB, the interactive printed circuit board layout system. 1 Introduction PCB includes a stand-alone program (called pcb) which allows users to create, edit, and process layouts for printed circuit boards, as well as a library of footprint definitions for commonly needed elements. While originally written for the Atari, and later rewritten for Unix-like environments, it has been ported to other operating systems, such as Linux, MacOS/X, and Windows.

Geda:gsch2pcb_tutorial [gEDA Project Wiki] Translations of this page are also available in the following languages: Русский. This is a tutorial on the process of using gsch2pcb as an interface between gschem and PCB. It assumes the gEDA, PCB and gsch2pcb packages are already installed and ready to use. Starting with gEDA 20030901, gsch2pcb is packaged with gEDA and doesn't need to be separately installed. This tutorial is functional and intended to generate results as quickly as possible. It is not a complete reference on gschem or PCB, but it does show with a simple example design all the steps one might need to take. The goal is to use gsch2pcb as the bridge between gschem and PCB so that the schematics can always be in sync with the PCB layout because all element additions or deletions in the layout will automatically be driven by changes in the schematics.

A first stab at reproducing Jennifer Kyrnin's massive HTML Special Characterset Guide was added 13 May 2013.

Using a Thermistor. Connecting to a Thermistor These thermistors are pretty hardy, you can strip the PVC insulation and stick the wires into a breadboard or solder to them directly. Of course you can cut or extend the wires. Since the resistance is pretty high (10Kohm) the wire resistance won't make a huge difference.
