Version 1.2 beta is released - 5 June 2007

It has been far too long since my last release! Though I finished most of it during the easter vacation, work has kept me too busy to put the finishing touches on it. Well, now I'm going ahead and releasing a beta with what I have for now.

So, whats new? Support for the HiTechnic NXT Acceleration / Tilt Sensor obviously. Also the code is now able to run under the Compact Framework (i.e. on a PDA).

But beside that I have tried to address various stability problems. As a result the code should have hardened considerably. It is not quite there now, but I hope it is getting there eventually.

One design decision I had made early on was to move to using nullable types whenever logically consistent. However this will make the endusers (that's you!) code a bit more complicated as you now has to check for HasValue == true and get the value from the Value property. I'm not certain that I will not regret my decision and revert to the syntax of 1.1. Please let me know what you feel about the new syntax.

HiTechnic NXT Acceleration Sensor code - 6 April 2007

HiTechnic has released it, but I haven't gotten around to supporting it in the API yet:
The NXT Acceleration / Tilt Sensor.

Fortunately Ronny H. has sent me his solution for a HiTechnicAccelerationSensor-class:

namespace NKH.MindSqualls
{
    public class HiTechnicAccelerationSensor : NxtDigitalSensor
    {
        public HiTechnicAccelerationSensor() : base() { }

        #region I2C protocol

        // X
        public byte Roll
        {
            get { return ReadByteFromAddress(0x42); }
        }

        // Y
        public byte Pitch
        {
            get { return ReadByteFromAddress(0x43); }
        }

        // Z
        public byte Yaw
        {
            get { return ReadByteFromAddress(0x44); }
        }

        #endregion
    }
}

Thanks Ronny!

Version 1.1 is released - 28 January 2007

Besides support for the new HiTechnic NXT Color Sensor, it is now possible to read the tacho count of a motor. Throw in a few minor bugfixes, and a lot of work on the documentation, and I give you v1.1. :^)

Special thanks goes to Giorgio T and Rui G for independently trying it out on the compact framework. It requires that the System.Timers.Timer, in the NxtPollable class, is replaced with either System.Threading.Timer or Windows.Forms.Timer. I can not help wondering why Microsoft has included at least 3 different timers in the .Net framework?! Unfortunately I have not been able to implement it myself without getting all sorts of nasty multi-threading errors. It will have to wait for v1.2.

Thanks to all that has mailed me with your comments and questions so far. I wish I had the time to answer you all in a more timely manner.

It is in the Mail! - 15 January 2007

Ah, finally... My HiTechnic NXT Color Sensor is in the mail, and should arrive within the week. Stay tuned for v. 1.1 of the MindSqualls API. :^)

TriBot Compass - 31 December 2006

While I am waiting impatiently for the release of the new and shiny HiTechnic NXT Color Sensor:

"... orders will be accepted in about a week and shipments will start around Jan 15th."

I decided to play around with their compass sensor instead: Your NXT compass?

The inspiration came from these two cool videos on YouTube: here and here.

Happy New Year!

Remote Control Application, Take 2 - 23 December 2006

Inspired by a mail from David J, I have made another example on a TriBot remote control application. You can find it here.

Seasons greetings to everybody, and may there be something special beneath the tree for you! :^)

Documentation Updated - 14 December 2006

The documentation is now available as a compiled HTML help file.

Remote Control Application - 12 December 2006

Added a simple remote control application for the TriBot.

MindSqualls v1.0 - 7 December 2006

Introducing MindSqualls v 1.0, a .Net library for remote controlling your LEGO MINDSTORMS NXT via bluetooth. Downloads.

MindSqualls is a .Net 2.0 library written in C#. It can be used with any of the .Net programming languages. I haven't tried it yet, but it should be possible to use with the Compact .Net framework as well.

I've been working on this project since I discovered release 0.2 of Bram Fokkes excellent NXT# project. It's been very inspiring. :^)
