[chbot] Great use of acceleration sensors for glove

[Michael Pearce]

Used the Freescale MMA7455 - I2C interface, and what the client
specified as they had been using a demo board with it on.... very easy
to talk to... just write a couple of registers to configure it....
then just read read and read all using I2C.

ST has a good range for less cost as well.

Take note: They are VERY VERY VERY VERY fussy about board layout and
soldering.... can be done with paste and rework station (hot air) or
reflow oven, but do not attempt to use a soldering iron... can kill
them or cause bad offsets and give inaccurate readings. Most likely
why most people just purchase them.


See a selection at link below.

Also see http://www.sparkfun.com  as they have some/or about to add to
their collection of development boards/kits.
