I was thinking that I would like to have a weighing scale to have on my bathroom so I can log my weigh... I am a bit over my body average, I am trying to get on the line, mainly because of my health and also look ;-)
I was thinking If I can found one on market, but I didn't... If someone can point me to a ready solution...
Since I believe it can be difficult to find it on market, I was thinking of what I need to make one for me, DIY, using an AVR and share the project on Code.Google (with purposes to get help from others and also help others in my situation) :-)
Can someone give ideas? as the sensor to use... the communication to PC..., etc...
I am recently using an AT90USB162, I am able to use MyUSB Lib.
I am imagining some kind of contactless card for storing the data, when I use weighing scale leave the card near it - weighing scale storing automatically the date and weighing.
On PC having a contactless card reader where I could read a file maybe of that with coma separated in TXT, so on OpenOffice I could make a graph :-)
I never worked with contactless cards... - I work on electronics with AVR, I am always looking for new projects for learning ;-) :-) -- I would like to start using the AVR32 :-)
Thank you :-)
