You know, we could also do this voice or something. I dunno. Also ring in for your choice of voice/text. I can go either way... :ph34r:

I'd be interested in one, I'm available Mon-Fri after 6pm PST (UTC -8). I greatly prefer Voice.

So we settled down on parts, 3 sensors + 1 Cortex M0 microcontroller (LPC1114) We cannot get any HMC5883 since none of the major electronic distributors (Digikey, Arrow, Farnell, etc) carries them. Looks like it’s still in its infancy. So, we have to end up with the expensive HMC5843 for now. Parts alone will cost us around $45 each board. I am not sure how many of you are still interested if that’s the case. Anssell (My supplier in China) will give me a quote on the pcb cost few days later so I will update you guys then. Oh and yes, you will need LPCXpresso (Another $20 investment) if you want to program the microcontroller yourself. The firmware will be burned into the microcontroller before I ship them out.

So, I got the quote. A fully assembled board will cost $80 each. Anyone still interested?

Do you want to post the Schematic and board files, Yonghan?

Okay. Money Matters. The cost of one single CortexIMU will be $85 shipped (Could be cheaper if more people chip in). For those who are interested, I will need everyone to pay a $40 non-refundable deposit for easing my financial burden to get the board made. Once it's made it will take me and Chris Seto some time to port the DCM algorithm to the board and when it's done I'll have you pay me the remaining $s before I ship it out preloaded with our port of DCM algorithm. I'll accept Paypal and Money order drafted on a U.S. bank. Please PM me for details... EDIT: Please chip-in ASAP so I can confirm the orders. Thanks.

Sorry if I bother you,

but I would know if there are some other boards available.
If so what exactly I have to do in order to get one?
Do you ship in italy too, if so what option you provide?
What would cost be?

Thanks for any details.
Paolo.

Chris Why you did not use LSM303DLH accelerometer/magnetomer ($5.25 Newark Distributor). Paul

Still new at all this but thinking of buying a couple of sensors to play with to understand what is at stake ... I liked the idea of having a 9dof sensor :) I'll add a GPS, Temperature and Barometer. Any good altimeter around ? And a few proximity sensors (for autonomous flying) ... Still need paypal prepayment of 40$ ? PM me ! Mike.

No change in features, but those are only projected features. Ultimately, I'm just gonna cram as much stuff as I feel is useful in the thing. I don't think we'll be short on features, but there may be extra stuff.

Ascended will be building the first 9 CortexIMUs by Pick-Place.
