Andras Schaffer commented on Adrián Nagy Hinst's blog post Portable Ground Station design, 2.0 - the basic idea
"No need for a 900$ Surface, get a Dell Venue 8 Pro  for 250usd... it also has full windows (not RT) and plenty of processing power...."

Andras Schaffer commented on Pitlab's blog post GPS-GLONASS
"Correct me if I'm wrong, but these modules have only NMEA  output with four decimal digits which is way less resolution than Ublox or mtk 1.9 firmware."

Andras Schaffer commented on Chris Anderson's blog post Finally: replace just the bent shaft, not the entire motor
"But if you crash and bend the shaft, it's almost sure that you have to replace the bearings too.
If somebody bending shafts weekly, then why not buy an arbor press for 30 bucks and replacement shafts for .99 per piece...."

Andras Schaffer commented on Andras Schaffer's blog post MultiWii 2.1 released, with Arducopter RTH and loiter based code inside
"It is NOT a Paris board, it's just a simple Arduino Promini (328P) and a cheap chinese GY86 sensor blob (MPU6050+HMC5883l+MS5611)
MultiWii had acc+mag+baro for ages, the new func is the GPS poshold+rth.

Here is a short video of poshold (loiter) in strong wind.During the last two months I was working on the RTH and poshold code for MultiWii, which is finally released some days ago with the 2.1 release. The code is mostly based on the ArduCopter RTH…

Andras Schaffer commented on CrashingDutchman's blog post MPU-9150 – world’s first 9-axis motion tracking device
"The main selling point of MPU6000 was the so called DMP, and offloading sensor fusion from CPU, which was turned out as a closed source implementation and Invensese refused to give any detail out to the open source community (including diydrones).…"

Hi!I had a couple of HM-TRP modules laying around, and gave them a try. However my modules were 868Mhz ones. So I went through the code, and it seems that the bootloader supports 868Mhz, but the initialisation part of the firmware is only for 434…

"There was a library in the svn, but it was removed for some reason. However you can still get it via versioning http://code.google.com/p/ardupilot-mega/source/browse/libraries/MPU...
Are we waiting for something more advanced or this is all what…"
