Adrian Thomas commented on Chris Anderson's blog post Birds have the best IMUs!
"In neurons that transmit action potentials firing an action potential is 1:0, but the signal is often in the frequency of firing, and not all neurons transmit action potentials - many just apply inhibitory or excitatory stimuli to other neurons.…"

Adrian Thomas commented on Chris Anderson's blog post Birds have the best IMUs!
"Most of that head stabilisation is driven visually rather than through inertial sensors. That isn't to say inertial stuff isn't important - I know of at least one peregrine that has some sort of offset in the system so that when she is hooded and…"

Adrian Thomas replied to Rick M's discussion Configuring Battery Monitor
"I've seen the same problem - APM Planner v 1.2.4 mav 1.0, set up the attopilot voltage/current sensor version, input the measured BEC voltage, go to flight data to check its working, gives a reasonable voltage, back to configuration and the setting…"

Adrian Thomas commented on Archangel06's blog post NASA's Auto Ground Collision Avoidance System....
"I thought this bit of the report was telling:
"
The last flights were not without a few glitches that are often the hallmark of experimental flight testing and software development, ranging from computer cooling issues in the ground control station…"

Adrian Thomas replied to Dr Mike Black's discussion APM2 Code 2.4 - Throttle problems
"You need to go fly mate, the frustration just builds up otherwise, until something flies ok. Having also just gone through gps-lock failures (Xbee too close to the gps, everything too cramped in the easyglider cockpit), I understand how you feel....…"

Adrian Thomas commented on Andreas M. Antonopoulos's blog post Parameters and their meaning: Dynamic Wiki Documentation
"Very useful. Shows up anomolies very easily. Two things.
Firstly, centidegrees. Hundreds of a degree or 0.01 degrees might be clearer, at least to me.
Secondly, under flight modes you have:

Adrian Thomas commented on Rob_Lefebvre's blog post APM2 and Rx All-in-One!
"@R_Lefebvre: no problem, the actual way to do it is much easier than what is in the wiki. Full telemetry would be nice, although already the signal loss warning is really useful.

@Veikko, will try tomorrow - don't have the unit here. However, it…"

Adrian Thomas commented on Rob_Lefebvre's blog post APM2 and Rx All-in-One!
"I got the FrSky D4FR to try setting this up. Neat, small cheap. Trivial to set CPPM on it - the instructions are clear, jumper on the signal pins of channels 3 and 4. CPPM out on channel 2. Easy.
So then I went to the APM2 and tried to set that to…"
