Look What's inside your Mem's Gyro:

Take a look at what's inside your Mem's Gyro on your VTOL.

It is amazing. This details the workings of the gyro in the new IPhone 4, but the same things in in that $10.00 Hobby King GA-520 Mems gyro.

Here's an excellent article about "Mems". Many great drawings and other fine details, it's well worth the read.

Mems are the "Holy Grail" of Inertia Navigation according to this article.

Hi Coro, unfortunately the link above appears dead.

Shame, because I was really looking forward to some photos!

I found it and here you go. http://read.pudn.com/downloads165/eb...y/13587_07.pdf

This article appears to be written around 2003/2004, so the information is a bit stale, but many of these devices are now found in those 10 dollars Mems gyros at Hobby King.

I'll edit the original posting so it work too.

Enjoy

Here one more good one about Mems in Cannon Shells. Very interesting!

Please note the Ring Mems, this was also shown in the preceding article from 2004. It appears to be very robust and reject interference. This maybe the King of Mems right now. The optical Mems (Moems) is going to be very nice some day.
