I've made a quaternion based AHRS with bonus altitude and temperature sensing using an AltIMU-10 and an Arduino Nano. It can print out orientation in either Euler angles (heading, pitch, roll), a north-east-down rotation matrix or as a quaternion over UART serial.
Hi Guys, I have been a bit slack with my updates lately. The Microstrain AHRS has been integrated onto the plane and the driver for LabVIEW real-time is working however I have run out of time to develop it for FPGA. I got it mostly working in FPGA but that last 20% was taking too much time so I just went for easy the RT driver that I had already made.…Continue

I've been working on an ARM based quadcopter over the past several weeks. It utilizes a custom sensor pcb that is essentially a break-out board of break-out boards from Sparkfun. The custom pcb also serves as power distribution to the motors. The MCU is an NXP LPC1768. It utilizes the NGX "Blueboard" development board. I've made all the firmware and hardware…Continue
