About Me:

I am an electrical and electronic engineer with a lot of background in FPGA system design and reconfiguration computing technology.


Please tell us a bit about your UAV interest

I like the concept of gravity defying objects and UAVs are on of them.

Hi GuysHas anyone tried running the I2C bus faster than specified in various device datasheets. Found an interesting articles making the case for it.https://groups.google.com/forum/#!topic/autonomous-electronic-systems/TSQgPiFQ1IkIt seems the basic…

"that is an idea that I have considered and in fact I have I do have a ODROID X2 in my possession that I do intend to use test a few ideas...  but I have had a few reliability issues with the board, namely the hdmi interface... will find a lot of thr…"

"Quick update. I've implemented the rate control feedback using the FPGA. I am testing the roll axis and just using the P-Gain which as can be observed, is a little bit too high.

"Anyone interested in Kalman Filters, great blog here http://blog.tkjelectronics.dk/2012/09/a-practical-approach-to-kalma...

Can be easily adapted for other applications"

"Just a little update. I implemented a complementary filter with a standard PID feedback loop and I have tuned to the best I can my gains. However, the Quadcopter is still not very responsive.

which leave me to believe that
a) the complementary filt…"

"The Cyclone V HPS range does look like a very attractive platform with dual core arm A9 and from 85K logic upwards...
And you are right, to go for altera, VIVADO does not seem to be mature enough for Zynq to be a strong competitor to the Cyclone 5 H…"

"I see, you are going for the FPGA = Dedicated accelerator approach rather than having an FPGA contain the entire SOC. That is great. The is exactely the route I eventually want to go down. But wanted to test a few ideas on a cheap platform before in…"

The focus of this image is the try and highlight the pcb I had to design (In Altium) to translate 5v signals for ESCs PWM and RX to 3.3v/2.…"

"Hi Morli

Thanks for the comment, I haven't done the maiden flight yet, I have a test rig with which I am testing the effectiveness of the PID controller. But I just can't wait to get this thing airborne. She is a real beauty. I don't know if I shou…"

"But just as a taster, the main bits of the system are the the DE0-nano FPGA board and the MPU6050 6degree of freedom IMU (gyro and accel). The FPGA board was reasonably cheap.... about £55 in the UK... so much to say about this work I jsut don't kno…"

I am tuning the PID gains to get the best response. I must admit it has been really hard finding time to work on this because there are…"

"Morli, thanks for the support. You are right, I think it could be of interest to some people, once the basic platform is up and running, that is why I want to share everything, it will be nice to have a community rolling around this idea... "
