Tom Kent commented on hiflyer's blog post 'C++ or Java?'

For people who want to get into the hardware side...running servos off of pin outs, grabbing serial lines, etc I'd recommend C/C++. But you said you're going to be doing AI research, for something like that, where it is removed from the hardware, an…

Tom Kent commented on Tim Trueman's blog post 'Insurgents Hack U.S. Drones'

I'm not convinced that it would bring anyone down on us. It could be baked in as just part of the protocol, like some other protocols are using. We could even use parts of the SSL/TLS library (without the complicated public key stuff), then it would…

Tom Kent commented on Tim Trueman's blog post 'Insurgents Hack U.S. Drones'

So should we make some plans to add encryption to the data link in our software? From my understanding, using symmetric encryption with pre-shared keys only adds a minimum of overhead. Even if there aren't serious concerns about people hacking into…

Tom Kent replied to john higgs's discussion 'I'm new to C++'

First, if you don't have previous programming experience, I would recommend that you not jump in and start with Arduino. I know that it would have quickly confused me if I had tried to start with that. Rather, I'd recommend spending some time workin…

Are you new to programming or just C++?

Tom Kent commented on Chris Anderson's blog post 'No DIY Drones chat tonight...'

I'd like to hear from someone who has worked with simulations software like flightgear, if you're taking suggestions.

Another good platform to compare to would be the small diameter bomb...it is a long-range glide weapon.

Even the pros haven't figured this out. I believe it was condensation in the pitot tube that cause the B-2 to crash on Guam.

You can find the HW docs here: http://www.tapr.org/gps_vpib.html
and the DGPS C code here: http://www.tapr.org/software_library.php?dir=/gps/DGPS/N8PXW Control software here:http://www.tapr.org/gps_tac32.html
You can still find these GPS units on ebay, but since they are 10 years old, current models are likely more accurate, as receiver noise plays a significant role.
