Premise & Background: Can you build a "LoJack" style asset tracking capability using open WiFi hotspots? The proliferation of cheap, lightweight WiFi embedded ("IoT") devices made me wonder. The WiFi association stack, DHCP client stack, et al. has to be incredibly lightweight and simple to fit in the firmware on, say, an ESP8266. If you programmed one to scan, find an AP, associate, get an address, and send a single packet - would it be able to do it fast enough to report its location from a moving vehicle? [Aside: This is actually something I've wondered about for years, but the IoT chips offered a unique and low-cost way to try it.] "But wait," you say, "there really aren't that many open APs these days. Most of them are captive or paywall portals, or at least make you agree to some goofy ToS." Right, but as has been pointed out multiple times by multiple people all the way back to Dan Kaminsky's DNS tunneling ta...
Hi, I am a L337 g33k female. I am an obsessive talker, with many hobbies, unique collections of old clocks, cameras, electronics, motorcycles, and cars.I found your unique blog/journal via Facebook, thru a friend of a friend, etc.
ReplyDeleteI just wanted to thank you for posting some really interesting stuff. I'm so sick of the usual blogs of various people postings of their lunch pictures complete with Taco closeup, pictures of their dog or themselves and the mood they or the mood of their dog are in at that exact moment of said photo opp. And of course, extensive braggings on their toddlers bowel movements during potty training. With that said, no i don't hate kids or animals. I adore both. C:
I found your 1964 IBM modem post, amazing! I knew the gov't and IBM had computers back then, but i had no idea IBM had any idea about modems or possibly the internet. Simply unreal.
Your pictures flying over the Sierra Nevadas were equally amazing. I noticed in the desert pictures, it looks like there may be geoglyphs. Similar to the Nazca Lines? I don't know if thats what they were in your desert pictures, but thats how I saw them. Very interesting. I need to take a trip West. (I'm in Dallas, TX)
Anyway, again thanks for giving me one more reason to use excessive amounts of bandwidth and 4G time well spent via my ahem, smart phone.
That is something I would like to see you mess with! Those big old cellular phone bricks from the latter part of the 80's. Michael Douglas from Wall Street, instantly comes to mind.
