makeRF: A Better Amplified Crystal Oscillator Transmitter
https://makerf.com/posts/a-better-amplified-crystal-oscillator-transmitter
Don't buy a radio; Build one! A Better Amplified Crystal Oscillator Transmitter. A couple months ago I posted a design for a bare bones amplified crystal oscillator transmitter. It turns out that it was a little too bare bones, and was in need of some improvement. After posting it online, I received some helpful feedback from the friendly folks at HF Underground. That pointed me in the right direction to brush up the design. I present an improved design for a crystal oscillator amplifier:. The power outp...

Don't buy a radio; Build one! ARRL Field Day 2014. I was able to carve out a couple hours this past weekend to participate in the 2014 ARRL. As I mentioned in my 2013 post. Field Day is a ham radio event that takes place the 4th weekend of June, where operators try to work as many stations as possible, while. Learning to operate in abnormal situations in less than optimal conditions. Aka low power), which also happens to be my favorite mode of operation. This has been the 3rd Field Day I've participated.

makeRF: Fun With Crystal Oscillators: Part 1
https://makerf.com/posts/fun_with_crystal_oscillators_part_1
Don't buy a radio; Build one! Fun With Crystal Oscillators: Part 1. Introducing the crystal oscillator. When a voltage is applied to the crystal oscillator it creates a square wave. You may also blow out your oscillator if it's not rated for 12v! You will have more stability with a 9v battery since it has lower voltage and lower amperage, but in turn less watts output. What will you hear? So, what will this little thing do? I created these two vines below to show you:. Click on the sound icon to hear.

Don't buy a radio; Build one! An LM386 Powered Crystal Radio in an Altoids Smalls Tin. Last year I was designing an Arduino powered doorbell. For my new home, and I reached for the trusty LM386. To build the audio amplification stage. But, at my new QTH.

Hacking My House #1.5: When Lightning Rings :: Mike Gualtieri Homepage
http://www.mike-gualtieri.com/posts/hacking_my_house_1_5_when_lightning_rings
Hacking My House #1.5: When Lightning Rings. If you read my last post. You saw my schematic on how to build a musical Arduino doorbell. After the doorbell was installed, I noticed that it rang by itself sometimes. Not often enough to be too annoying, but enough to think about correcting the issue at some point. I noticed it rang sometimes when a large appliance clicked on, like the dishwasher or central air, and even sometimes when getting a static shock on a light switch. The filter consists of a small ...

Moving Your Landline To Google Voice. Even though I use my cell phone as my primary business line, it's always been nice to have a second more public line, so I decided to try and keep the number. I've been using Google Voice as my voicemail service ever since I got an Android device, and I knew Google allows you to port a phone number to Google Voice. Bingo! Unfortunately, I soon found out that it's only possible to port a mobile number to Google Voice. Here are the basic steps:. I also went online to A...
Build an Arduino Word Clock :: Mike Gualtieri Homepage
http://www.mike-gualtieri.com/posts/arduino_word_clock
Build an Arduino Word Clock. A few months ago I came across an interesting project, an Arduino Word Clock. If you aren't familiar with the term, it's basically a clock that tells you the time as a sentence instead of with digits. So instead of 10:30pm, it would say,. It is half past ten. The reported time accuracy is within 5 minutes, which is good enough for a general clock / interesting piece of art. I decided to build one as a Christmas present for my dad. Creating the clock face. The nice part of the...

Hacking My House #1: Building a Musical Arduino Doorbell. Earlier this year my family and I had the good fortune to move to our first home.

Growing up, my father built a doorbell that played the first two measures of Pictures at an Exhibition. The following code is based on code from 30 Arduino Projects For The Evil Genius. Is released open source. The code creates a sin...

The Rockmite: A 40 meters CW QRP Rig (in an Altoids Tin). Computers dominate most of my time. My job keeps me tapping on the keyboard most days, and my love of learning about new technologies (and administering my many Gentoo Linux machines) keeps me tapping away most nights.

For the Rockmite is a ham in Tennessee communicating with someone in New Zealand! Here a...

Don't buy a radio; Build one! Last weekend I was browsing the internet for radio circuits and came across an interesting design I've never seen before, nicknamed the. The design apparently originated in 1996 in an amateur radio club QRP publication. The name originates since. The original author claimed he built this transmitter. With it in just 10 minutes time. Impressive! And was able to load up frequencies 6925 kHz, 14322 kHz and 28266 kHz without problem. Click to read more. Posted: Feb 25, 2016.
