dunk commented on Melih Karakelle's blog post New Opensource LRS Coming
"have you considered using an AVR with more 10bit timers than the ATMEGA328P ?
this would allow you to do servo PWM in hardware leaving the microcontroller with far more time to do other things.

i use a single ATMEGA2561 to run a 2.4GHz module,…"

"hey Pete,
it's the same version of the program.
yours should look the same as my screenshot.


the bright yellow you are seeing are part of the raw images.
pyGame should make the yellow bits transparent, letting the layer beneath show through.

so,…"

"hi Pete,
on a windows VM i can't reproduce your findings.
it's a clean XP install running Python 2.6.6 and pyGame 1.9.1release-svn2575 .
it works fine for me.



is there anything unusual about the machine you are running?
i'm wondering if this is…"

"hmm. that should be similar enough.
odd.

it's late here but i'll have a dig about tomorrow and see if i can find any information on transparencies working differently on Linux and windows.
they *should* work the same but it is possible we've run…"

"hi Pete,
that appears to be a problem with transparencies.
the yellow area should be transparent.

i suspect it's an issue with pyGame...
any idea what version of pyGame you are using?
i'm using '1.9.1release' on Linux.

you can find out by running…"

"thanks everyone for the interest.

hi Rana,
hehe, that would kind of defeat the purpose of doing it my self though...


Simon,
hmm, not a bad idea. i think i have a windows virtual machine somewhere.
how does py2exe work?
anyone who uses my code…"

hey guys,this might be of use to some of you:i've scripted a set of basic instruments in Python that might be of use to some of you.the Youtube clip shows it attached to my UAV project.for anyone who hasn't used it, Python is a particularly easy to…

dunk replied to dunk's discussion motor noise affecting accelerometer readings.
"for anyone who's interested,
i solved this problem.

the issue was nothing to do with the accelerometer and everything to do with EMF from the power wires affecting the signal wires from the accelerometer.

in a stroke of blind good luck, the…"

hey guys,i have built an IMU of my own design into my homebrew RC system on a fixed wing airframe.i am using a MMA7260 accelerometer on an ebay "prototype PCB" along with some rate Gyros for the IMU which is proving quite robust while gliding.the…

dunk commented on John Arne Birkeland's blog post Long range R/C control and two-way telemetry
"@John:
o, absolutely. sorry if that reads a little more critical than i meant it.

i've spent a great deal more time than i expected implementing a 2 way communication method where as you've skipped that step with off the shelf modems and got 90% of…"

dunk commented on John Arne Birkeland's blog post Long range R/C control and two-way telemetry
"i've been following the project Thomas links to from a distance.
it is a very well conceived project but (in my opinion) does lack a central project page so there is a lot of reading of the rambling RCGroups thread before you can appreciate the…"

hi guys,first post.so this post would fit in the "RC Equipment" section as well as here...i started working towards a UAV around 6 months ago. it's something i had considered for a while as a natural extension of my robotics hobby.since then i've…
