The Challenge of Amateur Radio

November 30, 2008 | General | By: Mark VandeWettering

Jeff KE9V, over at is once again falling victim to pessimism about amateur radio. I can’t help but shake my head at the effort that we as hams seem to put into lamenting the impending death of our hobby. It’s very strange. I can’t think of another hobby that spends as much time as […]

Pico-Satellite Solar Cell Experiment (PSSC)

November 29, 2008 | Amateur Satellite | By: Mark VandeWettering

I just head that Endeavor will eject a small picosatellite (5x5x10 inches) that will test two different types of solar cells in the environment of space before it begins its deorbit maneuvers. I was interested in seeing if I could find any downlink frequencies for it, but haven’t managed to do so. I did find […]

Keyboard Acoustic Emanations Revisited

November 29, 2008 | Computer Security, Cryptography | By: Mark VandeWettering

While my blog has been dominated by radio related stuff lately, I do continue to be interested in lots of different subjects, including various topics related to computer security and codes. While scanning my feeds today, I found reference to this work, which I hadn’t seen before, but which I find interesting both for its […]

Movie Review: Bolt, in 3D

November 28, 2008 | Movie Review | By: Mark VandeWettering

Tonight I took my wife, son and future daughter-in-law out to see Bolt, Disney’s newest animated feature. For extra bonus points, we went to go see it in 3D (yep, with the Real D glasses and everything). I am somewhat skeptical about the long term viability of 3D. People seem to be highly variable in […]

ATMega Controller

November 27, 2008 | General | By: Mark VandeWettering

I’ve been playing around a little bit with the Arduino microcontroller board that I bought a while ago. It’s a nice little board, but there are some alternatives that are also interesting, like the following board from Futurelec. It’s got more I/O pins (lots more) than the Arduino, and is based on the ATMEGA128, with […]

Changing my theme…

November 27, 2008 | General | By: Mark VandeWettering

My WordPress “theme” seems to need a little maintenence. Don’t be alarmed if the look of my website changes a bit over the next couple of days. I haven’t upgraded it in a long time, and I’m trying to make sure it works with all the upgraded versions of WordPress that I’ve installed recently.

Happy Thanksgiving!

November 27, 2008 | Amateur Satellite | By: Mark VandeWettering

In my house, we celebrated the holiday yesterday, to give my son a chance to go and have Thanksgiving dinner with his in-laws. So I made a turkey, a ham, two pumpkin cheesecakes, potatoes, stuffing, a ratatouille, some gravy and a bunch of veggie appetizers. My future daughter-in-law made some green bean casserole. My wife […]

You seem shorter than I remember…

November 25, 2008 | Amateur Radio | By: Mark VandeWettering

When you get an amateur radio license, you are issued a callsign. Mine was KF6KYI. This was a “2×3” call, which means it had two digits, followed by a single region digit, followed by three letters. These are issued sequentially, which means they aren’t particularly aesthetic or short. If you want to spend a grand […]

NOAA 17 this morning…

November 25, 2008 | General | By: Mark VandeWettering

My blog indicates that I was decoding my first NOAA weather sat images about a year ago. I have made some progress on improving the images that I get out, but not alot. Witness this morning’s image, recorded beginning around 10:05 PST of NOAA 17 on 137.62 Mhz: It seems pretty good, except for one […]

New Morse Paddles

November 22, 2008 | Amateur Radio | By: Mark VandeWettering

Today I had a few minutes to finally put together this pair of small Morse paddles that I got from American Morse. They have a very nice “milled aluminum” aesthetic that I like a lot. By themselves, they are a little light, and tend to float around a bit, but they include a tapped hole […]

Simple Mandelbrot Movie

November 20, 2008 | General | By: Mark VandeWettering

I was bored. I had five minutes. I wrote some C code. A few minutes later, I had this movie. YouTube – Simple Mandelbrot Movie This is also the first time that I have tried to use the Youtube “annotation” functionality. Works pretty well. Wish I could overlay even a static, transparent image, similar to […]

Holy Crap.

I’m really, really tired of watching the economy implode.

Grid Beam Building System

November 19, 2008 | General | By: Mark VandeWettering

I ran across a reference to “grid beam construction”. I didn’t know what it was. Now I do, and it’s kind of neat. Like a kind of Erector set technology for grownups. Grid Beam Building System (Heard about it from The Citizen Scientist)

Short Book Review: Hands-On Radio Experiments

November 17, 2008 | Amateur Radio | By: Mark VandeWettering

I needed something to read on a plane trip this last weekend, and a quick stop at Ham Radio Outlet had me leaving with a copy of Hands-On Radio Experiments by Ward Silver, N0AX. Ward writes the “Hands-On” column each month in QST, and this book is nothing more than five years of his columns […]
