Thrustmaster F22 USB Conversion - Part 2

Submitted by gerry on Fri, 03/13/2015 - 13:46

Having done some more research, it turns out that the chips in the handle are not MCUs, or at least not all MCUs. A few are shift registers, and, according to this post, talk SPI. The post also has a bit of code to capture the buttons.So, despite having the matrix all built, if I can just use a Teensy and build on that code, all the better.

Homebrewing an Off-centre Fed Dipole

Submitted by gerry on Wed, 03/04/2015 - 13:44

During HF field day 2010, I had occasion to get some experience with the off-centre fed dipole, in this case, a commercially made unit from Buckmaster.
Prior to this, I had heard that OCF dipoles ‘are a compromise’, ‘are noisy’, ‘are deaf’, ‘have wildly varying radiation patterns’ and many other negative comments. During field-day, our experiences definitely gave me cause to doubt the nay-sayers.

Thrustmaster F22 USB Conversion

A friend of mine bought me a Thrustmaster F22 for my birthday (thanks John!) a good number of years back, and I had many a fun sortie on DID's excellent EF2000 or F22 sims. It spent much of the last 10 or 12 years gathering dust rather than blowing away bogies, however, and due to the progression of technology, is no longer useful. Or at least this is what I thought, until I came across the controller modding community.

Signal Generator using Adafruit SI5351 Clock Generator

Submitted by gerry on Sun, 01/04/2015 - 13:38

The DDS and related clock generation circuitry has made possible high accuracy, broad-banded programmable VFO functionality for very little money. Analogue Devices' AD9850 series offer HF frequencies for about €5. Higher frequencies can be had for not much more money, with the Silicon Labs SI570 with its near GHz maximum frequency offering the highest.

Arch Linux Upgrade Breaks EFI Dual-Boot

Submitted by gerry on Thu, 12/18/2014 - 13:35

I recently started using Arch as my primary distribution on my laptop. I made this change for a number of reasons... mainly that I did not like the direction that Ubuntu was going in, and I kind of missed the hands-on approach I had experienced with Slackware and Debian.  I wanted to recapture the control that first drew me to Linux nearly 20 years ago.

KIM Uno - 6502 emulated on Arduino

When I was young, about 11, I was lucky enough to be bought a Commodore 64, the computer that introduced a generation to computers, and likely launched thousands of careers in computing, mine included. It wasn't long before I started to feel constrained by the very basic version of BASIC that it ran... 2 character variable names, no labels, no loops apart from FOR, no allowances to structured programming whatsoever.
