Morning GJH105775, Yes you are correct the HUD information is introduced onto the video link on the Quad using a telemetry video overlay module. If you pop back to the previous page of this thread about two thirds down the page there is a bunch on information (video & basic schematic) showing...

Evening all, I have such a fun hour or so this afternoon flying and testing out the Quad ! Hugh in answer to your questions regarding the Sonar altitude hold .... it works really well. The Arducopter firmware appears to switch between the Sonar and the barometric sensor automatically and...

Afternoon Hugh, I don't seem to be suffering any interference problem at all at the moment. All the 12V gear is running from a dedicated UBEC and looking on my scope the supply looks nice and clean. As I mentioned I also fitted a simple single pole RC filter to the supply input to the Sonar...

Morning Quad people, I can report back the ground sensing Sonar works REALLY well :) Mounted the module in a little box and mounted the box to the rear of the Quad - only space I had left. Three connections to the Arducopter A0 port. As recommended I also fitted a simple power supply filter...

Evening people, No video 'this time' but I have acquired a new module that I am very excited about (must get out more) ! Got my hands on a XL-MaxSonar EZ4 MB1240 module - this little module is very cool in my opinion. It has approximately a seven meter range +/- 1cm ... well here is the spec...

Hi Dean, Cool, welcome to the world of crazy quads :) Also a long way away in sunny Bristol but good luck finding a flight buddy ! Cheers, Dave

Hi Hugh, I was expecting a problem when I put the OSD & telemetry modules in such close proximity and thought I might have to add some RF shielding tape. However, so far I have not had an issue with any type of interference. I did make a conscious effort to keep the main 5.8GHz transmitter away...

Evening everyone .... Bit of a posting tick on my part :) Ok, I looked at changing the enclosure on the video recorder and in the end decided to keep the aluminium enclosure supplied as the weight difference compared with a new enclosure was negligible and not worth the hassle swapping. I...

Morning all, It's a posting bonanza :) Now I have the OSD module fitted and working I really wanted to be able to record output from the FPV camera with the overlay information also included. I could simple record this on the ground as my monitor screen has the ability to record video...

Evening one & all, As promised attached is a simple schematic showing how I integrated the OSD module, telemetry module, Arducopter, camera & power together. The switch can be seen multiplexing the module Tx lines into the flight controller. Notice the RF PA is sourcing the 12V power after...

Good evening everyone, I have been having big fun modifying my Quad and adding new & interesting things :) First thing I have removed the Boscam TR1 integrated camera & transmitter. I have spent some time playing with this camera but unfortunately have come to the conclusion that the low...

Hello Hugh et al, Yes the FPV transmitted output appears to have poor dynamic range. I suspect the HD recorded data has a similar issue but it is less noticeable due to wider dynamic range. It's a bit difficult to say for sure because there is very little information available. I have looked...

Hi Hugh, Sorry for the delay in responding ....... Yes the neckstrap works very well, in fact better than before the monitor was fitted. I replaced the dry cell battery box with a 2200mAh recharge but this had the effect of making the Tx bottom heavy - the new monitor counteracts the weight...

Evening all, Today I got my hands on a 5.8GHz FPV receiver and screen. The little 5 inch unit also operates as a PVR and has a 32Gb micro SD in the side allowing recording as well as viewing. The screen fits to a bracket which then fits to a lightweight carbon fibre bracket that mounts onto...

Good afternoon guys, I have been having fun flying and testing this afternoon. I am very pleased with the Quad now, it is flying really well - very stable and responsive with a nice 14 minute flight time. This afternoon I have been working on improving the HD camera stabilization. The Boscam...

Hi Hugh, You are completely correct the battery connectors are polarized ..... and should be fool proof. Turnigy batteries are supplied with a bullet style connector which as you say is polarity sensitive. I have been using a bullet to XT60 adapter to connect to the APM power module rather...

Hello & good evening ! I have not forgotten the forum ...... been working on the Quad and have now got things to report. First off, one reason for the delay is that I made a school boy error ! Even though I do electronics for a living managed to reverse polarity connect the battery ...... too...

Hi Hugh, Ah ok, I have gone for it and ordered up some motors to give me a bit of power headroom. Looking at the image of 'the bits' it looks like the nuts are possibly Nylocs. I have a load of Nylocs in the workshop so will pop some on should the supplied nuts be a standard type. Yep, as you...

Hugh, Question for you ..... Do you have CW & CCW prop hubs for your x3108s motors - I am having a hard time finding a supplier of CCW hubs in the UK :( Cheers, Dave

Yep, we have blade servers at work and they need crazy cooling ! I think we used these little 1 inch fans a few years ago sat on top of the older generations of Xilinx FPGA for cooling. The ones we use now (Kintex 7) don't need external cooling and so the fans were obsolete - but perfect for...
