  • of the 164W/sq meter that reaches the surface of the earth and/or the 1400W at the edge of space… how large a surface of panels can be installed before we begin to affect the planets weather… oh, that’s right, there is no such thing as global warming.

  • the reason is very simple: you are at their website… they are not at your.

  • Before ‘fly by wire’ I read a report out of DoD about a study comparing Joysticks to Forcesticks for tracking control of a dot on a screen… bottom line was the average operator could become proficient using the forcestick 50 times faster than using a joystick. I haven’t lately, but the last time I looked for a reasonably price, non-trivial forcestick they were pretty pricey. So for $14, this looks like a good start on a project.

  • Anyone made a comparison between this and the Microchip MM7150?

  • because I have a lot of old engineering s/w, my main 2 machines use XP/SP3 so IE has pretty much outlived it’s usefulness. I have been using Firefox for a while and it is OK. I tried Chrome a few years ago but it kept blowing up on some of the sites i visit… like semiconductor manufacturers and other engineering oriented. I just tried Chrome again, yesterday and was pleasantly surprised at it’s speed… yes, on a 13 yr old XP machine.

  • only if the image fits in a few bytes.

  • if the delay seems excessive make sure you have 220 ohm termination at both ends of the twisted pair

  • coverage map: http://www.findmespot.com/en/index.php?cid=109 the birds never get more than 52 degrees N/S so antenna tilt towards the equator when closer to polar lat’s should improve performance.

  • SPOT probably doesn’t care to test it above that altitude…

  • If you are having trouble, make sure the voltage to the satellite transmitter is good, that is critical and the reason G* spec’s lithium primary cells, they maintain their cell voltage ‘till near end-of-life. if you’ve got an alt. supply, make sure it has low source impedance, no voltage sag while radiating.
