FYI I already have 5x each of the accel and gyros, I could probably ship a few out to those who would help.

Hi Jonathan

 

If you need anyone to place components I have all the equipment for production.

 

Screen Printer

Pick & Place

Yes that'd be perfect! I'll let you know when the schematics are finished.

Hi Jonathan,

One thing you may want to consider is to pull all of the current header pin type connectors off and create a wire harness that routs all external connections (inputs and outputs)  on the board to a standard bulkhead connector, Glenair Mighty mouse (these are really pricey), or a standard sub D type connector. I would also route any indicator, LED's, out through the connector. The reason I'm suggesting this that   once the AP was assembled it would be installed in a light weight shielded box an never see the light of day again. The disadvantage is that this will increase the over all weight and size. Just a thought

As I announced yesterday, we will be releasing cheaper, simpler IMU shields early this year.  This is an open source project, so you're very welcome to use our designs and we love people make variations that suit their own purposes better than what we make. But we will have something in the marketplace that addresses your price concern, at least.

You could try replacing the FTDI chip (and maybe even the main micro controller?) with one of the usb avr chips, e.g atmega32u2.

@Thomas: what we're doing with the next APM/IMU combo is moving the PPM encoder chip to the atmega32u2 so it can also serve as the USB interface. That means the IMU shield doesn't need to do it and we can remove the FTDI chip and connector.

Chris, does that mean the PPM input/output on the APM is driven by the FTDI of the IMU shield?

Hi Jonathan ,

if you need only gyro and acc you can hack wii :) See multiwii project only .. it's a good toy:)

pete, I am making a board similar to what is requested on this page too, only for the regular ardupilot, if you are willing i could use your help too, also I could adapt my board designs for use on the ardupilot mega.

my project page can be found here: http://diydrones.com/forum/topics/ardupilot-imu

thanks
