magnetometer
More hours in a day, lol.
Oh how i wish that could be too lol, what with work & such, there's so many ideas to be done with these cool picaxe chips, if i win the lottery then i would have all the time (or more time) in the world to experiment & such lol.
I remember when i first heard about the basic stamp kits, it was a dream for me, the only thing that bugged me about the basic stamp is that they had no real ADC's, one cool option they had onboard was the DTMF output which was handy in some of my projects, but they was quite dear in price so i was only ever to afford 2 of these.
Then the PICAXE came along with the ADC capability built in amongst many other options, very cheap compared to basic stamp, free software to program them & very good technical support.
My projects have rocketed since the PICAXE's came out.
Anyway enough of bigging up the PICAXE lol, one major problem i had with the magnetometer is temperature drift, but using the temp sensor DS18B20 & then processing differences with the picaxe nulled this out almost 100%.
Previous versions of my magnetometer before, i had to implement my temperature nulling out via circuitry & calibrating, which was alot more messing about, time consuming & not as accurate.
Well off to bed now, got an early morning tomorrow.
Yours,
Mark
