Re: Arduino UNO R3 or FC
Eating my words now as those cheap Naze32s are no longer supported (Betaflight) and the STM32F4 development boards found for around $10 can be used for a 450 Quad and is smaller than the 2560 Mega I used to fly with.

Re: MWii development beyond v2.4
The last Multiwii I built was when I ported over to the Atmega 1284p. Given the price and size of 32bit flight controllers since then, I had moved on to ready-made flight controllers like the Naze32, Flip32, CC3D, and KK. Leaving a collection of electronics behind that were collecting dust. I had go...

Re: Arduino UNO R3 or FC
All of my first several flight controllers were home-built using Atmega microcontrollers and/or Arduino boards with gyros, barometers, GPS, etc. But they're big. Especially my Mega. I started pissing around getting them smaller by etching my own PCBs but it was quite labour intensive, and a huge was...

Re: Motors violently jump when going above half throttle
So far I have just run them from the receiver while calibrating ESC. I am thinking the ESCs are incompatible with them. But then again, like I said, I see the motors bundled with what appears to be the same ESCs from several sellers on eBay.

Motors violently jump when going above half throttle
Hey guys. I'm wondering if any of you can shed some light on some motors I'm using. When I go above half throttle, the motors jump or shake a bunch and make odd sounds, and if I push them, the ESCs will smoke. Everything immediately heats up when this happens. I have tried all three motor timing iss...

Re: Chinese 450 Frame Battery Securing
Thanks for the hint. I love that. Tried finding some suitable staps but nothing yet.
But I think even cargo strapping with washers might work equally as well.

Re: DIY flight controller issues
You probably have issues with your gyro / acc orientation.
Ensure your axis orientation is set properly for your sensors or your gyro will be conflicting with your acc.
You want your gyro and acc to match so when you pitch or roll, everything is on the same page.

Re: Different motor rpm
Just reading about these vibrations and about how to cancel unbalanced motor "bells" with a vibration sensor and had a thought. Has anyone ever had the idea to use a vibration sensor on the flight controller to cancel out any vibrations the acc / gyro may be sensing?

No, it is definitely the flight control software. But I've pretty much got it figured out. I have everything where it needs to be now except for my AUX channels.

Using Multiwiiconf for my Gui. I haven't tried it on the others at this point, but they work fine with my other flight controllers I have thrown together.
And that is correct. Aux3 and Aux4 move together in tandem. Nothing on the roll.

Re: Atmega (1284p) Multiwii -=Almost Fully Functional=-
There are no other pins on PortC.......
Best I can tell, and I can double-check tomorrow, is that D19/PC3 is for whatever reason reading as Aux3 and Aux4 (at the same time), and nothing reading on the Roll designation. Appears to be a software issue.

I have had that issue before when messing around orientation. My conclusion was that it happens when your your ACC and Gyro contradict one-another.

Re: Etching PCB
I have been testing those all at 5v without problem. The 521 and 273 are 3-5V. The BMP-180 is 3.6V but I seem to recall the board has a regulator and has a 3.3 line off of it (just look at your pinout) you can use to power other 3.3V components if you like.
