@cyberteq - You can get better than 10m, by waiting and averaging. Certainly the relative position will improve in accuracy by doing so. It is repeatable from one week to the next and very accurate. The absolute position can be improved with WAAS. LAAS will be <1m most of the time. The satellite signal we use is the same signal the military uses, but their receiving equipment is different, and much more expensive. There is no longer any encryption in the signal. So I don't know what you're talking about.
I got a open logic sniffer, probes and a generic 16x2 lcd red on black (could you believe I had not bought one yet?)
no it seems to update rather quickly and cleanly for an LCD, I wish it had a better contrast though as the backlight leaks out everywhere so its more like red on slightly darker red but I think some tape will help that
I got a GPS module from some outfit in China off ebay for something like four dollars, still haven't unwrapped it from stat bag.. No reason to think it's anything other than fine. I got a great deal, but it's reasonably easy to find them for around ten bucks or so I would imagine (thinking dealextreme or whatever).I was reading and waiting for Crossroads to chime in.. So there's obviously a reason.. So what is it? I am talking about VORTAC, a radio beacon network that back in the stone age was used via signal triangulation off the frequency/tower chart to give pretty dang accurate positioning. I am supposing it's a resolution issue to use actual VORTAC, but (I really don't know) would low power radio triangulation work within the range of reasonable open air lower power beacons? GPS for large scale with finer granularity coming from triangulating off of local ground beacons of known position... Got one of the elcheapo bluetooth serial modules, which arrived yesterday. The seller says it is 5v tolerant though the module is labeled for 3.3v .. Its got a backplane board of some type. Anyone running these with TTL and 5v before I cook it?
Astronomy and photography people like red. Fish tank people like blue. Both are inverted displays.
