"Took me some time to create it but here it is http://diydrones.com/forum/topics/v911-new-circuit-board-upgrade-ha..."
I have a little project going. I'm planning to create a new circuit bored for the v911 mini helicopter or at least thinking about it. First goal is to make an open source alternative that is as good as the original, but where it's possible to build…
"Looks like there is some interest. I'll open a thread in the forum for updates and more input :)"
"Morli: Don't know I'll test how much it can carry when i get it. But none of these components are heavy. And the original circuit board looks pretty bulky.
The reason for the post is to see if someone has done something similar and failed"

"I want to make the board, thats part of the project :) I'll keep you updated and start a thread if I get any where with this"
Has any one played with the v911? Just ordered one and thinking about making a new circuit board for it. Making it a really cheap open source drone. What do you guys think?STM32F103CB vs atmega328MPU-6050nRF24L01 vs A7105
"Ok now loiter is working more or less, it is a little aggressive but it holds the position. So I tested RTL, and that works to. BUT when it gets back to it's launch position it circles for 5 sec or so, then FALLS OUT OF THE SKY!!!! Tried it twice…"
Just awesome state estimation, using particle filter and kalman filter. To bad the laser scanner is $5000
"Still getting bus errors but the performance is much better. Not getting closer to this mystery"
"I went back to v2.3 of the firmware and now suddenly alt-hold is working with baro :) Still struggling with loiter tough."
"Just did the test, no errors while running of battery (BEC) power. AKA no luck :("
"Just realized that the last test was done on USB power, maybe I'm on to something. I will try with battery(BEC) power tomorrow"
"Ok now i tried running the test found in the library folder, you can see the output in the shared folder.
Baro:
No erros with the logic analyzer
Mag:
Still no errors with the logic analyzer"

"Ok forget the (while motors are running), looks like I can get errors any time. But as of now it looks like they might be coming from the baro. I guess this will be a pain to replace. Any one got experience with this type of problem?? Or toughs on…"
"Ok getting pretty sure about it being a I2C bus problem. I get errors on the bus when i test it with the motors running. Not sure what the cause is yet, but at least it's progress.
If you want to see the output it's under the link above.…"
If you want to see the output it's under the link above.…"
"OK so since the baro and compass is acting up it's pretty clear that this must be something on the I2C bus (I think). So I hooked up a logical analyzer, to see what was going on. If you want to see the result visit the link under. Have not had time…"
