I am trying to figure out how I can interact with 4 load sensors (like this http://manyyear.en.alibaba.com/product/359992876-210312211/MLC902_Micro_sensor.html
. I think this might be similar to this one: http://www.sparkfun.com/products/10245
I am actually trying to hack a body weight scale which looks pretty similar to this one (see attached pic or link http://www.dietsinreview.com/diet_column/wp-content/uploads/2009/09/escali-track-and-target-scale.jpg
I just want to use it with arduino so either just replacing the original board or trying to get the output from the original pcb to use as input to arduino will work for me. Specifically I want to output to serial from Arduino to the computer.
There are loads of info about the subject on the net, but none of it helps as they mostly relate to other prototyping boards.
Here are some links you can find on the net:http://www.nerdkits.com/videos/weighscale/
this is not ok from the start as it uses a 1 load sensor instead of 4. Really interesting tutorial video, though!http://cerulean.dk/words/?page_id=42
Another good tutorial! Unfortunately it uses another type of sensor and, again, it uses a single sensor.http://scanlime.org/2010/01/hacking-a-digital-bathroom-scale/
Really nice hacking project! Unfortunately again, here she uses a different prototyping board and, even though she presents the hack as simple, I have a different body weight scale, so I am a bit confused. http://code.google.com/p/casainho-projects/wiki/SdCardBathroomScale
This body weight scale looks pretty similar to mine! And the hack is really good. From what I understand, he is hacking into the info goind to the original LCD. But again, using different board and lots of cables
Any thoughts? Anybody finished a project like this?
