Traffic lights

Mon, 12/23/2002 - 10:25am

Today I've been working on the algorithm for the traffic lights controller. At first, potentially lethal situations occurred frequently as I let cars on both road cross at the same time but it works okay now.

Because there are no lights in the Lego Mindstorms set a small motor is doing the traffic light's job: a rotating motor is green, a slow rotating motor is yellow and when the motor is off it indicates the light is red.

Bought a Christmas tree today too.

Message from Finland

Sat, 12/21/2002 - 4:51am

Dear Guus,

seasons greetings from Finland, the home of the late Sta Claus.

I hope you are not too sad about this, it is a cruel world.

Best wishes to you and your sweet Sasha.

First prototype!

Thu, 12/19/2002 - 12:39pm

OverviewI've just started my first real prototype of a traffic light controller.

It's made using a Lego Mindstorms set. The controlling software is written in Esterel, which is one of the languages I want to use in the real projects too. However the hardware is 'just' a processor, not an FGPA.

A week after the ice

Thu, 12/19/2002 - 12:34pm

A week after I made these pictures there is no ice anymore in the Spaarne.

In the Nieuwe Gracht you can still see some ice though (click on 'Read More' for a picture).

Christmas at Chess

Thu, 12/19/2002 - 7:32am

Unfortunately the appointment in Eindhoven didn't go on. Today I'm reading "Computers as Components" by W. Wolf, about embedded computing system design.


The building here is decorated for Christmas. Some quick pictures.

Scenario

Wed, 12/18/2002 - 10:37am

Artist impression of scenario 1: a traffic lights controller.Yesterday and today I've been thinking about a scenario to use for my internship. It shouldn't be too complicated (due to limited time) but at the same time it must be complex enough to make comparisons of the various methods possible.


My current plan is to make a small-scale traffic light controller: a crossing of two roads with tiny traffic lights that are operated using the system I'll develop.


I spoke with my supervisors at Chess today and they liked it, although it still needs some refinement. Tomorrow afternoon I'll go to Chess in Eindhoven to meet a few people there.

Aïda!

Wed, 12/18/2002 - 3:10am

Aïda.Yesterday evening we saw Aïda -- and what a magnificient show! The voices, music, decors and actors were all great. We had a wonderful evening.


The show took about 2,5 hours and we were home around 1:30 o'clock. There is a fan website that has a very nice Flash intro that shows a few highlights of the evening.
