It's alive, It's Alive!!
I was successful at mounting my Gyro chip on a PCB. Plus
the circuit works too. Really, really neat.
I had a PCB layout done for me by ExpressPCB.Com, I then
applied some flux onto the PCB and carefully placed the
chip. Then I used a hot air rework station to carefully
heat up the stuff and solder it down. Of course you have to
carefully hold the chip in place to prevent it moving as
the hot air flows under and around it. It took about three
seconds to heat it up real nice. You could tell as the
solder started flowing as the chip would drop down ever so
I am planning a project submission for the DPRG website
detailing my PCB layout for a combo low cost
Gyro/Accelerometer system on one PCB.
Of course low cost is relative. Right now the Gyro chip
costs $39.90 in single units, and the Accelerometer costs
about $29.90 in single units as well. So we have about
$20.00 for the PCB (piggy back with other layouts), $70.00
for the two chips, plus maybe about $10.00 for other
assorted parts like capcitors, inductor, regulators,
So it looks to be about $90.00 or so, to build one up. But
then a while back another company wanted something like
$4500 for a gyro chip setup. So in that case it is low cost.
But it is really cool, works nice, the gyro is real fast
and very sensitive to small tilt changes. The Accelermeter
allows you to compensate for the creeping gyro errors that
occur in things like a two wheeled balancing robot.
I love it when things actually work. It is so hard to debug
and fix things in the unknown never been there before area.
