Hello to the Little Red Daemon
By Dermot Tynan, about 11 years ago.
After much tweaking and hacking with configuration files and kernel build options, I finally have a FreeBSD 8.3-RELEASE kernel and install running on a Wrap board. Technically, it's NanoBSD, which is a scaled-down FreeBSD install, which boots from Compact Flash. The WRAP board is the PC Engines forerunner to the ALIX. When National Semiconductor and AMD stopped making Geode chips, the guys at PC Engines had to stop making their very popular WRAP board. I still have a few of them tucked away, for emergencies such as this.
Bon Voyage, Snoopy!

Today, March 23rd, 2013, Team Joker are planning to launch their ninth boat, Snoopy Sloop. This has been an educational (and obviously fun!) experience for Robin Lovelock and his fleet of robotic warrior boats. Here in Beoga Beag land, we wish them well.
Of Laylines and Beats

This time, I set the simulation granularity a bit smaller, so the updates are more regular and there are more data points, which explains the curved route in some cases. You can click on the image for a slightly larger version. An Olympic course is known to sailors as a "triangle and sausage", because you sail upwind to the top mark, turn onto a broad reach to the gybe mark, gybe around, and broad reach down to the leeward mark. From there you beat back up to the windward mark, and then turn dead downwind to the finish line at the leeward mark. A true Olympic course would put the start and finish line about a third of the way up the beat, shortening the first leg somewhat, but also making for an upwind finish as you would have to sail around the leeward mark and beat to the finish. I skipped all that!

The Software...
By Dermot Tynan, about 11 years ago.
I've been asked recently, about the software platforms used on board Beoga Beag. This seems as good a time as any, to talk about the various layers. As mentioned previously, the lower layer is a custom board, running an ATmega8 Atmel processor. The software (Igor and Otto) is custom-written in C for the boat.
