Adr1an,

this is the best explanation so far... Thanks for taking your time and sharing this with us. =)

I think after reading and reading and reading... and going thru all the math, this is the most simple, and most compreensive text on Kalman filters I ever read.... and some times thats all we need  smiley-wink

thanks for posting,

Tony

wow, it works now... I guess it was bad luck... maybe site on maintenance or something....

thanks!

Hello Guys,

I've seen a lot of codes and videos, applying the Kalman filter. But I did not find an easy, and well explained text on this subject yet.

I got one question about this, as far I see people use accelerometer + gyros... Is there an way to apply Kalman's filter on a single 3 axis accelerometer?

Thanks in Advance,

Tony

iria ser legal se tivessemos um hackerspace aqui na região. Mas não sei quantas pessoas estariam interessadas em se reunir semanalmente para trabalhar em projetos eletrônicos.

Pessoal, estou morando aqui em campinas, próximo a unicamp. Se encontramos pessoas o suficiente aqui da área, poderiamos organizar um workshop...

O que voces acham?

O arduino tem a eeprom, existe uma biblioteca pronta... muito facil de usar.

TiagoCS,

a ideia é legal, porém você terá uma surpresa quando passar pela alfândega... segundo as leis brasileiras, você pode comprar do exterior sem pagar impostos, pelos correios, somente até a quantia de 50 dolares no total, incluindo o frete... e vai por mim, o preço dos impostos não são nada agradáveis...

boa sorte!

Antonio

This is an Arduino forum. So the real question is, "And how can I make it play a tune?"  Smiley Smiley

hahahahaha thats so true!

I think that is Harmonic related...

is there anyone on the forum with experience on building "Harmonic Trap Filters"?

Hey Eric,

one easy solution is to find out if there is no tracks right on the top of the original reset button... and drill a hole on the shield... so you can reach the reset button with a toothpick...

at least for now it would work...
