The first ever demo for Lego Mindstorms NXT

category: code [glöplog]
 
Hi,
this weekend Hardread have released the first ever demo for Lego Mindstorms NXT. It took 3rd place at Function 2011.
I don't know if any of you have such a brick at home. If you do, please test it :)
Btw, you can find the video version in the release (this video has 'edited' music, the device itself plays etremely low bitrate music!)
The device has a 48mHz ARM CPU and a 100x64x1bit LCD screen. Free storage is about 100Kbytes, that's why the music is so poor quality.

This was my first prod for this hardware, there is still a lot of possibilities to improve.

Question, suggestion are welcomed.
Bye, pohar

I don't remember but I think I voted this up.

I have no idea what the actual device looks like though, but I love the idea of doing something with it.

When I saw the title slide, I expected to see some lego robots doing some show. :)

NXT demo? That sounds interesting! I haven't seen the video so I don't know what you did... but was it just using the screen or did you build demoscene effects with Lego and then drive them with the motors? Cause that would rule!

evilpaul: that would rule indeed! spinning a cube wouldn't be hard to code I guess ;D

evilpaul: this is only software, we didn't use lego bricks.

I made a simple demo for the nxt a couple of years ago in a summer camp. Just a checkerboard rotozoomer, but this had inspired me to do something more...

I can only guess that the coprocessor does float operations. But I will learn more about it.

Any clues on how to get the video to play? Or is there a youtube available? Quicktime won't play it, VLC plays audio but just shows a black screen. The fact that it decompresses from 4mb to 114mb makes me suspicious that something is going wrong ;)

This are the specs of the video:

Video
ID : 0
Format : RGB
Codec-ID : 0x00000000
Codec-ID/Info : Basic Windows bitmap format. 1, 4 and 8 bpp versions are palettised. 16, 24 and 32bpp contain raw RGB samples
Dauer : 1min 49s
Bitrate : 8 192 Kbps
Breite : 400 Pixel
Höhe : 256 Pixel
Bildseitenverhältnis : 1,563
Bildwiederholungsrate : 10,000 FPS
BitDepth/String : 8 bits
Bits/(Pixel*Frame) : 8.000
Stream-Größe : 107 MiB (98%)

Audio
ID : 1
Format : MPEG Audio
Format-Version : Version 1
Format-Profil : Layer 3
Format_Settings_Mode : Joint stereo
Codec-ID : 55
Codec-ID/Hinweis : MP3
Dauer : 1min 39s
Bitraten-Modus : konstant
Bitrate : 192 Kbps
Kanäle : 2 Kanäle
Samplingrate : 44,1 KHz
Video Verzögerung : 22ms
Stream-Größe : 2,29 MiB (2%)
Ausrichtung : Aufteilung über Interleaves
Interleave, Dauer : 110 ms (1,10 Video-Frame)
Interleave, Vorlaufsdauer : 500 ms


Such a high compression is easily doable when the source material is uncompressed bitmap and only features 2 colors. Rar usually does the job exemplary good (as you can see). I am using smplayer and it works pretty fine with ffdshow codecs installed.

I plan to make two different youtube versions: screen grab (included in the release) and a live capture.

coming soon to cinemas near you!

Ah, right. Some odd windows format, but it seems to work nicely for size. Played OK in vmware/xp, but no sound there, had to play it in vlc/osx at the same time to get both audio + video :)

HD video capture with good quality sound, NOT the sound of Lego
