Wow that is amazing.

Would using 2 or 3 chips like this produce even more impressive results?

I notice there is some horizontal jitter in the lava field section, between 1:42 and 2:02.
I guess you are running short on the time needed to do the calculations accurately.

At University of Gent (molecular genetics department), we weigh the plants to determine if they need water. This way we can water them very precisely and there's no milliliter of water given to much or to little.

Parallax for piano

just heard your paralax for piano and entered your hp through www.remix64.com . anyway, I think you should release another piano-istic remix. I saw your last release is from 2001! I bet some ppl in the "scene" would appreciate another tune like that.
cheers,

A case against syntax highlighting

Anonymous
Sun 6-Apr-2008 18:29
I think you have a case for a lot of languages, but one interesting case is that of LateX - without syntax highlighting you really have to stare at the screen to see if you've written \subsection{} which is an operator, or subsection{}, which the typesetter will parse as normal text. By the way, I know that LateX is not a programming language, but I feel it's relevant.

Nice job you did. I will study the work you made and try to learn from it. Iĺl put a post on my blog about it as soon as possible.

Great Job, impressive!

One small hint for prototyping boards. The vertical "bridges" are looking a bit messy (i know, its a prototype).

Before using silver wire: Unroll 1 Meter of wire, attach it to a fixed object, grab the other end (with a gripper) and pull it hardly. Now you have very straight silver wire which looks quite nice :)

Thx for the idea of gluing the layout onto the board, i will give it a try....

One interesting thing missing in the schematics is a suitable value for the capacitor.

The amount of current would be very small. And the time it flows can be minimized by providing 5V on the sensing side when not measuring resistance, in effect giving very ner zero volts of difference between the electrodes.

Electrolysis would happen to a very small extent, but it can be minimized in the same way as the current.

Time to put that gold jewelry to use! It won't dissolve if used as electrodes.

The magnetic field would probably not be strong enough to be measurable with affordable instruments, given the small current.

Plants tend to grow, thus gain weight. How do you calculate the amount of plant growth?

Good point. I'm using a 10 uF electrolytic capacitor.

Hola! I`m working (for now copying =]) on your project but i have problems... What kind of diode do you use in this board?
Thanks for your good work!!! (and excuse my bad english)

Glad you like it! =) I'm using 1N4148 diodes, but anything with a forward drop somewhere around 0.7 V should work.

A fantastic solution to the problem, when the experts wanted a brute-force approach! Congratulations!

Really impressive. I'll be showing this to friends at KTH (kth.se), and probably build one or two. On my main lab board I have an AT90USB chip, which has to run at 16MHz to support USB, so I'd guess that means lower horizontal resolution. I think an Xmega could be really impressive, using its DMA engine to output high resolution colour signals.

You should compose some nice tunes for it and share them :)

I am completely amazed by Fratres and am listening to all the versions on my online music service as the piece is new to me. I see it is also your favorite piece. But when I looked it up on Wiki the text citing your analysis seemed a little dismissive of the piece where it says: "The chord sequences themselves follow a clear pattern, and while the progressing chords explore a rich harmonic space, they nevertheless appear to have been generated by means of a simple mathematical formula." Were you saying that the piece is somehow simple or mechanically created? Just wondering, your thoughts appreciated.

The word "simple" has many connotations. By no means do I consider Fratres trivial or hollow. Nevertheless, the sequence of notes can be described by a comparatively simple formula, as I've described in the analysis. This makes Fratres amazing, for the same reasons that a mathematician may consider a brief, elegant formula much more beautiful than a complex formula. Simple, in the case of Fratres, means pure, elegant, perfect.
