The Pink Princess Laser Modulator

Last weekend, a bunch of us from the Vienna Wireless Society set up a table for a Sally Ride Science Festival held at George Mason University. This is annual event, which promotes science, math, and engineering for girls in grades 5 to 8. Part of the fair takes place outdoors in the morning and early [...]

Attic Antennas Are Go

Last week, I stuck a RCS-8V remote switch in the attic, and ran some RG-213 and a CAT5 control cable down to the shack in the basement. The switch has five ports (plus the common feed port), so there is lots of room for experimentation. Just in time for the Vienna Wireless Society 10m net [...]

Texas Topper QRP Amplifier

I seem to be doing well enough running the Kenwood B2000 at 5W or the TenTec 1320 at around 4 watts, but I haven’t made many contacts with my Rockmite, which on a good day puts out around 250+ mW, but less when the battery runs down a bit. A while back, I had ordered [...]

Lessons Learned, part II: Rules

Continuing my over-analysis of TWIFcomp, which is now several times longer than all of the code in the competition combined, I thought I’d take a look back on the rules and see how they panned out. I thought that a comp about short works should have a short list of rules, that they should be [...]

TWIFcomp: Programming Languages

Histogram showing number of games per language

61 games, 18 languages. Just under 8k of code.

Here’s how the programming languages were distributed. A good day for Inform 7, but not a bad showing for URQ and other languages dedicated to CYOA. Also, unix scripting languages and shell tools were well-represented.

Number of Games per Programming Language

Of course, this isn’t [...]

A few minutes of fun

I stumbled upon a fun little web toy written in Java. You can create particles of various substances and they are released into a gravitational well that pulls them towards the center of the display. The substances interact in various ways, and you can sit back and watch the simuation run. For instance, you can [...]
