Comment on Controlling a robot arm using an ez430 Chronos by Christian

Christian — Sun, 01 Aug 2010 15:48:30 +0000

Hi Srikanath,

an easy thing you could do is grab the accelerometer data the same way I did, smooth it (e.g. using a Kalman filter, a sliding average or alike) and try to recognize certain gestures using some sort of classifier or neural network (probably support vector machines).
Another thing that could be done is to modify the firmware and add some menu to it. But that involves quite some in-depth knowledge of the ez430′s hardware and MSP430 programming. Something I’ve never had time to dive into.

hope that helps,
Christian

Hello Christian,

I am having similar watch and our university is carrying out few projects on this. We are planning to start a new course on this watch next semester. Can you help me write a code to control the lights of a room with either a click on the watch or by hand movement (acceleration data)? Please help me through this…

Thanks,
Srikanth Sistla.

Comment on LogicAnalyzer – extensible logic debugging by Steven

I’m no java expert, so I’m having some trouble building LogicAnalyzer. I wouldn’t even be building it at all except that the 32-bit tarball on SF doesn’t run (immediately quits with no output) on 64-bit Ubuntu.

I imported the sources as per the wiki page, and now I have >100 errors, all of which seem to be complaining that the @Override annotation needs to be removed. What did I do wrong?

Comment on List of references plugin for WordPress by Christian

I don’t think you’re doing something wrong, sounds like a bug to me. I’ve just checked how I use the plugin and it’s exactly the same way you describe.
Unfortunately there’s not much I can do as it works on my machine

I’m trying to use this plugin and it’s not working for me either.

I have title attributes on all my links, then I put [lor] at the end of my post, but still nothing shows up. What am I doing wrong?

Comment on Scala and building DFA’s from regular expressions by Olivier

Olivier — Wed, 24 Mar 2010 11:16:24 +0000

Just what I needed: an implementation of regex derivatives as a practical support to Brzozowski’s paper.

Thanks a lot for sharing this. I’ll check Scala out on my way back.

Da würden mir schon noch ein paar Namen einfallen:

z.B. John Bosak http://www.ibiblio.org/pub/sun-info/standards/xml/why/xmlapps.htm – ohne ihn wäre XML nicht geworden

Charles Goldfarb – der Vater von SGML ohne das wir XML nicht hätten

Bertrand Meyer – dessen Buch “Object-Oriented Software Construction” eine der besten Einführungen in objektorientierung war. Er hat “Design by contract” eingeführt.

Nicht zu vergessen die “Gang of Four” …

Die Leistung von Bill Gates ist eigentlich “Coputer for everyone”.

Was machen wir mit Steve Jobs – er hatte die Vision des Computers als Alltagsgerät.

Comment on Learn instead of building time machines by Daniel

Daniel — Tue, 05 Jan 2010 23:48:25 +0000

Yup, mathematics could exist without the universe, but the universe not without mathematics

Though i never understood on what assumption the universe-ceases-to-exist “time traveling rule” is based. Your paradox could be easily resolved by “you learn, get an A -> there never was the need for a time machine”. Thus the timeline in which the time machine was build would erase itself.

Nevermind, i anyway should be in bed since hours…
