mmormota replied to Shivam Gupta's discussion HD video + audio transmission using RF
"If the video quality is more important then latency (~500msec) and size, check the Hides DVB-T system.  "

mmormota replied to Mamoon Syed's discussion High Definition, Low-Latency FPV?
"Check my sample video (Hides HV-310):
https://vimeo.com/104337989

The output power is only 1mW, so don't expect high range without amplifier."

mmormota replied to Kelvin Tan's discussion Kickstarter long range hd fpv and telemetry - too good to be true?
"Please show us pictures of the actual device(s), technical details (inputs, outputs, resolution, fps, compression, latency, modulation, power, antenna etc), demo videos recorded on earth (how clear and smooth, choppy or not, what happens if there ar…"

mmormota posted a discussion in Andropilot Users Group
I am working on connecting  my own controller panel to Andropilot using Mavlink and Bluetooth. Most functions are working, however I have some questions:- the red "Looking for radio" warning keeps on screen after Bluetooth connection, the HUD, Map e…

mmormota commented on Tim Nilson's blog post Carl Zeiss "Cinemizer" OLED Goggles for FPV Use
"Hope it is not vaporware... It shown up on IFA2010, but nothing happened after the expo.
I definitely buy one when (or if) it will be available."

mmormota commented on Roberto Navoni's blog post What IDE Do you prefer for Multipilot32 - Ardupilot32 ? Arduino like Framework vs CooCox for Arm MicroController .
"Arduino is simple and rather good for the first steps. It's easy and effective for simple projects.
 
But the lack of debugging is just not acceptable for larger projects. You have to figure out tricks for testing code parts, blinking leds, oscillos…"

"Installing Eclipse is easy, but plain Eclipse is not an Arm IDE. Selecting the proper plugins, and configure them is the real problem. There are different version of Eclipse, different toolsets and plugins. Not all of them working together. There ar…"

mmormota commented on Roberto Navoni's blog post What IDE Do you prefer for Multipilot32 - Ardupilot32 ? Arduino like Framework vs CooCox for Arm MicroController .
"Coocox supports jtag, but only two proprietary adapters: Colink (ftdi variant) and ColinkEx (using an ARM uC).
It's Eclipse based, so the functions are similar.
 
What I like in Coocox:
- free and unlimited
- easy to install on Windows (to the contr…"

"The rendeingr made from an Eagle pcb?
If yes, could you please tell me the library items for the miniUSB connector and the right angle pin headers?
I just finished a pcb and I like to make a nice rendering too, unfortunately I can't find the above p…"

mmormota replied to mmormota's discussion centripetal acceleration compensation
"Of course the sign of the acceleration value is important (compensate to the left or right). However I think first check if the basic idea is OK, and such details later."
Oct 9, 2010
mmormota posted a discussion
If I understand well, the current centripetal accelaration compensation is based on the d_fi / d_t from the z gyro and the v coming from the gps. I think it's only correct if there is no wind, because computing the acceleration this way requires the…

mmormota commented on Sys-Ak's blog post Crash 4 Sure: integrated Autopilot & OSD
"Thank you all for the kind words.
Sys-Ak is sleeping now - I try to answer the questions.

Are you doing video sync generation and all of that stuff with software?
Yes. A DMA channel feeds the SPI port so the core loading is minimal.

Is video getti…"

mmormota commented on Janne Mäntyharju's blog post Making of XBee-pro 868 based r/c controller
"Thank you for the fast reply.

I definitely range tested them using the highest power settings. The range test was done with the stock program set, not with my RC application.

Good news that you have succes with the range. Probably my modems are fa…"

mmormota commented on Janne Mäntyharju's blog post Making of XBee-pro 868 based r/c controller
"I tried this modems using the evaluation kit. The range was way below the specification, shorter then my Futaba FASST gear. It has problem as close as 1km, clear line of sight.

Did you range tested the modems? I am curious if my boards are faulty o…"

mmormota commented on William Premerlani's blog post Invensense gyros in the UAV DevBoard
""We only briefly considered the ITG3200. In terms of drift and working range, the IXZ500 seemed a better fit, with a range of 500 degrees/second, which is adequate for most aircraft"

Worth to take a closer look. ;-)

I tried it with a BMA180 in an…"
