Antenna Analyser Project. This VSWR analyser looked interesting from K6BEZ.
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: "1000000C" sets the DDS output to 1 MHz. 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. Click the image to open the PDF file in a new window: Ham Radio. When you’re an Architect. Don’t get me wrong.
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. Calibrated Background Noise Generators.

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.
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. The Arduino analog input is limited to a 5 VDC input.
If you wish to measure higher voltages, you will need to resort to another means. One way is to use a voltage divider. The one discussed here is found all over Amazon and eBay. Feel Extreme Workbench Envy After Seeing The Tempel. For those of us with space to spare, our workbenches tend to sprawl.
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?”
And we have covered this in the past. Arduino. Raspberry pi/ arduino/ related. Radio. Ham Radio. STM32. Raspberry Pi - Projects 2. Rapsberry pi2. SparkFun Electronics. Getting Started with PlatformIO and ESP8266 NodeMcu. The Arduino editor, while functional, has never been a pinnacle of productivity and usability.
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. 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. The Sparkfun Rotary Encoder has 12 steps but others may have more or less.
The diagram below shows how the phases A and B relate to each other when the encoder is turned clockwise or counter clockwise. Every time the A signal pulse goes from positive to zero, we read the value of the B pulse. 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. While PCB can be used on its own, by adding elements and traces manually, it works best in conjunction with a schematic editor such as gschem from the gEDA project, as gschem will create a netlist, make sure all the elements are correct, etc.
How to make a Car - Powered Car - Very Simple. 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. Electronique. Arduino. ASCII Characters By Keyboard. A first stab at reproducing Jennifer Kyrnin's massive HTML Special Characterset Guide was added 13 May 2013. (13 May 2013) How to create alternate characters, such as foreign characters, those with diacritical (accent) marks, symbols, etc.
[Numbers MUST be keyed on the Numeric Keypad, NOT on the top line of the keyboard.] This listing does not begin to be exact; different platforms and servers handle these codes differently. Further, I have not yet checked out each of the nearly 700 codes and results. Garage Door. 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. Why subwoofers blow: slam, bang, pop, and sizzle.
