"I see the attraction of replacing the RC-link by 2 phones - years ago (2004/2005) I did this in a project I called "CellRC". The problem was GSM-CSD latency in the order of about half a second. Latency could be compensated by AP functionality,…"
"I think it's an overkill to buy a 2nd android just for motion processing. Kalman (7state) and expanded DCM become alive with 250Hz even on a 32MHz Xmega A1 (Look for Atmel's new Xplained boards and Xplained sensors, also kiXAHRS - much cheaper than…"
"Sorry, the discussion unfolds at RCgroups now. I had loved to see it here - but the interest in the project at RC groups is larger than here. If you are interested, please follow the story at RC groups. Thanks, Natatius"
Hi , Atmel has recently released the new (blue) Xmega A1 Xplained board (29 USD) and plug on sensors ATAVRSBIN1 (Inertial One, 54 USD) and ATAVRSBPR1 (Pressure One, 24 USD). A few days ago ATAVRSBIN2 (Inertial Two, 54 USD) expanded the line of…
"Hi Bill,
I learned from our discussion how deeply certain engineering paradigms sit inside our brains. Some of them even develop the status of a sacrilege ("Never ask.."). Initial offsetting seems to belong to this category.
We agreed that initial…"

Hi all (especially Bill & Doug)I wonder why "analog" offsetting is done for the gyros and accelerometers at program start? Why not filling omega_I with appropriate startup values instead? This way the code gets a bit leaner and kind of…
"Hi all,
the configuration crashed last weekend - the sausage is gone. While on Saturday we tested the basic AR7212 functionality - and it worked even forgetting about a range test - just perfectly - on Sunday we tested the DCM-autopiloting with the…"

Hi guys,I'm not sure whether I should post it here, but I feel that the problem I have been struggling with might be of interest for those of you who would like to squeeze out more functionality from SFE's Razor 9DOF.The starting point of the story…
Hi all, well, from my old-fashioned opinion there is currently too much discussion about the best way to do AHRS in this forum. Kalman versus other approaches like Bill Premerlani's one. Remember that the whole DIYDRONE story started with the…
