I know it's illegal in the US, but VHF/UHF and HAM radio equipment is f***ing expensive. I was browsing 850/1900 MHz repeaters and it looks like the maximum legal cellular transmit power is something infinitesimal like 3.5 watts.
So... What I'd like to do is fire up Garmin Mobile XT's PC-based map managing utility and map every AT&T and T-MoUSA tower within ~500 miles of my house (2,000lb cars with 1.5L engines and a 5 speed ftw, except when they malfunction outside of free towing range). Then I want to either purchase or make a somewhat large directional antenna (not sure which kind, asking here to see if the mods or somebody knows whether or not this is even possible before sinking dozens of hours of research into this) to plug into an amplifier. By amplifier, I don't mean one of those FCC licensed ones. For emergency situations out "in the sticks", it'd be handy to to have 25-50 watts of transmit power attached to a directional antenna that's pointed right at a tower. AT&T has 95% of the places I roam covered with EDGE and all of it's 15 kB/s glory, but then there are the capacious swaths of "middle of nowhere" that I like to hike in several times per year for several days at a time. Usually I bring friends, and at least every couple of years some f***tard inevitably tags along and isn't used to irregular terrain, 90+ Fahrenheit temperatures with relative humidity in excess of 90%, proper equipment (particularly cold weather gear; coldest it's gotten here in my 21 years is 7 Fahrenheit, and I still went duck hunting), and is generally unprepared falls and breaks a bone, develops heat exhaustion and/or heat stroke, or some other f***up due to being ill prepared. When I go that far out into the "boondocks", I don't take my old Civic hatchback with ~200k miles before the speedometer and odomoter died; I take my heavily modified 1986 Ford Bronco (351 CID/5.8L Windsor V8 with nearly everything that can be done to it while remaining naturally aspirated, 3 speed + "granny gear low" standard transmission so kinda a 4 speed but 1st/granny gear doesn't get used on anything like normal on or off road driving, 2 radiators + huge water pump, dual 25 gallon gas tanks + a 55 gallon drum I can swap out the back seat for if I need that much fuel onboard, Dana 60 front and rear axles, snorkel, no carpet, vinyl seats, a 6" custom suspension lift, 35" M/Ts with 1-4 spares depending on what I anticipate driving on + some A/Ts that I use for city driving when my POS civic is taken apart for repair or hauling heavy sh*t with my 450 lb-ft of torque @ 1800 RPM [gotta love getting t-boned by a drunk cardiovascular surgeon + suing the sh*t out of him in this overly-litigious society/pay for college and drop ~$20,000 into a $3,000 truck]).
That truck is supremely good at getting out of cellular range, and it sucks when sh*t hits the fan out in the sticks and I have to drive dozens of miles at high speed over rough terrain and thus tear up suspensions like a mofo to get ahold of 911 and an ambulance or a dust off (one dude broke his C7 vertebrae out there, had to get him helicoptered out) via my old Kaiser (kthx external antenna jack; I wonder if I can solder one onto Rhodium when my warranty expires) and 40" magnetic mount antenna. It'd be a lot easier to get ahold of EMS if I could build a hellacious amp and a large antenna that's collapsible/easily taken apart and reassembled to save space when not in use and I could drive to the tallest hill in visual range (if not one, check topo map for nearest), deploy that rig, aim it at the nearest tower, and make an 850MHz GSM phone call.
If it's possible, inb4 requires 1337 soldering/experience with radio equipment; I've built 1 HAM radio and repaired 8, fixed some CB's, and have hundreds of hours behind a soldering iron.
So yeah, if it's feasible to build such an inline amp please sound off.

demonstrated tech that enables devices (demonstration includes the G1) to be charged wirelessly..
It's been talked about for a while, but nothing concrete has been shown before!
Supposedly available within 12-18 months!
Topic sounds very interesting
But I couldn´t open the link
The emitter has to be very powerful for the charge current to be high enough on the device being charged. There's also a huge waste of energy that grows exponentially with the distance. This is one of the reasons this technology has been primarily used for short range applications so far. This is exactly how wireless keyfobs/smart cards work, but their useful range is limited to 1 meter or so and their consumption is minimal in comparison with mobiles.
Heck, I even have my electric toothbrush charging this way and my electric tea pot drawing power from the base wirelessly, but effective range is millimeters in these cases.
Nobody knows for sure what kind of effects strong electromagnetic fields have on humans. Knowing that electric impulses drive our brains and bodies too, I think strong electromagnetic fields are more than likely to cause major interference. IMO it'll be a while before healthcare people approve use of this kind of chargers.
Not a single regulation violated, pretty cool if you ask me:
Built by Mike Tassey and Richard Perkins, the Wireless Aerial Surveillance Platform (otherwise known as the WASP) is a flying drone that has a 6-foot wingspan, a 6-foot length and weighs in at 14 pounds. The small form factor of the unmanned aerial vehicle allows it to drop under radar and is often mistaken for a large bird. It was built from an Army target drone and converted to run on electric batteries rather than gasoline. It can also be loaded with GPS information and fly a predetermined course without need for an operator. Taking off and landing have to be done manually with the help of a mounted HD camera. However, the most interesting aspect of the drone is that it can crack Wi-Fi networks and GSM networks as well as collect the data from them.
It can accomplish this feat with a Linux computer on-board that’s no bigger than a deck of cards. The computer accesses 32GB of storage to house all that stolen data. It uses a variety of networking hacking tools including the BackTrack toolset as well as a 340 million word dictionary to guess passwords. In order to access cell phone data, the WASP impersonates AT&T and T-Mobile cell phone towers and fools phones into connecting to one of the eleven antenna on-board. The drone can then record conversations to the storage card and avoids dropping the call due to the 4G T-mobile card routing communications through VOIP.
Amazingly, this was accomplished with breaking a single FCC regulation. The drone relies on the frequency band used for Ham radios to operate. Not wanting to get into legal trouble with AT&T and T-Mobile, they tested the technology in isolated areas to avoid recording phone conversations other than their own. The duo play to discuss how to build the WASP at the DEFCON 19 hacking conference.

Let it hack my g2x, my phoe will probably knock it down when it reboots, or gps will take so long to lock up the drone will run out of juice.
That thing is a felony arrest waiting to happen.

Probably not breaking any laws as long as they are given permission to record the conversations (which are their own so far).

1984 Big brother comming our way
In my quest to reverse engineer the Blu Studio 5.3 docking port, I'm considering taking the phone to a friend who works at a radiology department at a local college and having him x-ray the circuit boards. But briefly I want to know: could this mess the phone up?
There were rumors that in the old days people used to use high-energy X-rays
to erase OTP (one time programmable) EPROMS/microcontrollers.
The were the same die as found in quartz window units but just plastic encapsulated for economy.
It was said that repeated erasure with X-rays might eventually damage the unit.
In any case, if it were mine, I'd have it X-rayed.
The digital imagers today use low level X-rays.
How many times have you sent your cellphone and laptop through the airport X-ray machine?
I turn mine off before putting it through the x-ray at airports but it shouldn't hurt anything either way. Just don't leave it in there for hours at a time or anything like that.
Good point on the airport x-ray machines. Thanks
This morning while searching ebay for reasonably priced solid gold toilets (or other things just as frivolous) I happened across a micro USB solar powered cell phone charger. It was priced at around $35, and while I had no real interest in buying something that probably doesn't work, it still made me wonder what if it did?
So lets assume my galaxy s3 is a 2100 MAh 3.8 volt battery, and it instantly charges to full when plugged in. This means it would consume roughly 8 watts every time you charge it from 0% to 100%. Lets not get overly technical and try to factor in the energy used by your charging cord.
Electricity in my state (New Jersey) costs roughly 21 cents per Kilo-Watt Hour (KWH). This basically means for every hour I use 1000 kilowats, I am charged another 21 cents on my electric bill.
This means if I charge my phone from empty to full exactly twice per day, I am roughly spending $1.23 per year to charge my phone. If the cost of electricity stays the same, it would take me 28 and a half years to break even on the cost of the solar charger.
how much would it cost you?
Since most of my charging is done at work.. cost me nothing.. Really though.. you are on to something... if only could mass market that and people would catch on then it would be great..
Well I think they'd have to really improve on solar energy technology before anything like this is realistic....I just saw the product as more of a novelty. Even if it does work its probably going to net you a couple percentage points an hour, nothing practical.
I just posted this on my facebook page and the response I got made me realize the smarter option would be to get solar panels for the house instead!
i think the purpose of a solar powered charger is for camping/hiking trips where electricity is not available and you can charge your ipod or phone

i should mention that the concept is the same for hybrid cars. you pay a premium for them for gas savings that could take awhile to pay off (not including special maintainence, etc)
but maybe be part of something bigger... be green
You could use your car charger that uses your car battery/alternator to charge your phone if you are worried about using your home electricity! Just like one post said its more geared towards camping/hiking our any outdoor activity where electricity isn't present.
I gave a gift of a radio that takes alkaline batteries, but also has (replaceable) lithium batteries that can be charged via DC adaptor, built-in solar panel or hand crank. The solar panel allows for the radio to have battery power from the rechargeables without having to crank anything, especially if this radio is kept out during the day at a beach or campsite. It has a connector for charging devices such as mobile phones, which would essentially take much of the day for a low charge - but, that is most practical for when other sources of power are not going to be available for awhile.
While shopping for that radio, I came across solar chargers that are dedicated to supplying devices with power and are thin, flat products that often unfold and have greater surface area than a typical device with a (small) integrated solar panel. Some of these are expensive, but your ability to put a more substantial charge into a battery backup (for general use) or directly charging your phone without any sources of grid-based power is the primary purpose, I feel. A Brunton Explorer2 or similar is something I would go for in these cases and the issue is not comparing their economy to grid costs of the current day, but long-term ability to have off-grid or backup sources of charging power when you need it, I figure. Plus, incrementally going green isn't ever a bad idea: if I owned a solar charger, I'd keep my phone off the USB or wall charger most of the time.

Don't think they're meant to pay for themselves, as they aren't alternative power sources - they are parallel hybrids meant to stretch the use of their gasoline engine.
Something like the Volt is a more serious version of that concept, being a serial hybrid whose wheels run almost exclusively off the electric motor.
Being "green" isn't always immediately the most economical choice in these relatively early days of people realizing it's beyond time to try and minimize the speed of global warming, etc. But, it's meant to be an incremental choice towards more responsible use of the dirty resources we know and love. IMHO.

You have to believe global warming exists in the first place. Just keep in mind there is as much evidence against it as there is for it.

No.
There is no scientific balance of evidence on global warming for/against its reality, and peer-reviewed studies have overwhelmingly shown its existence in a rather cold and analytical manner since at least the 70s.
Sure, businesses that seek to run away from taking responsibilities of their own pollution creation - from manufacturing or as outputs of the products they offer - do fund a number of pseudo-scientific PR studies to attempt offering the appearance of a scientific debate to purposefully keep the public wondering and debating, but no counter-evidence exists on the existence of global warming as a general phenomena in the scientific community. None.
Science is all about testing and retesting, then testing assumptions again - global warming is an easy reality to measure. Causes are still being studies, but the big ones are generally well known, and ways to mitigate are still being researched and even tried.
The business PR effort to offer an appearance of global warming debate in the scientific community utilizes easily debunked, pseudo-science at every turn - usually from privately funded studies, but sometimes they gain like-minded adherents who simply run with the misleading interpretations of highly particular data sets as part of gaining a subculture of defiance against . . . something. The man, government, smart science, whatever your cultural bugaboo might be. This is trap that people such as Michael Crichton have fallen into.
The anti-climate science PR push is equivalent to those many years of tobacco product manufacturing and distribution companies funding misinformation about the effects of cigarette smoke on human health, influencing USA lawmakers and a portion of the public to take sides against rather simple scientific facts . . . until that dangerous farce finally ran its course.
There is no scientific "debate" against the reality of global warming, and your preference for V8s (which I grew out of decades ago) has no impact on climate science - only your perception of such, perhaps.

I'm not trying to convert you: you're simply wrong, dangerously so. I'd like others to see that your unsupported "opinion" (which is actually willful ignorance - for which you haven't offered a shred of evidence) - seems entirely counter to talking about actual science that can power or be otherwise useful in using our favorite pieces of techology . . . which were created, in essence, by people who studied one or more disciplines of science. Actual science, that is.

Interesting discussion. We can try to be civil to one another though...
That said, my 2 cents:
Recent data does support that global temperature is rising. The question that's hard to answer (and has been unproven to date) is whether this warming is man-made. Could man-made pollution be a factor? I think so. Is it THE factor? That's open for debate.
Hybrid cars: just food for thought - how are we getting rid of all those batteries?? I can't imagine those battery-acids are earth friendly.
....and no one is even discussing about the EMF generated by hybrid cars. EMF is ionizing radiation - ie. it has enough energy to break DNA (cancer risk, people!!). So if you driving a hydrid or a Volt/Leaf, you're sitting inside a pretty high EMF field. Personally, I can't take that chance with my little kids.
Solar panels. I think they're promising. Would love to get solar panels for my house. (1) too expensive. (2) efficiency sucks. Best panel is only about 20% efficient. Hopefully this will get better soon. Sunlight is free. Might as well figure out a way to use it!

I have the Nexus 4, an awesome beast at an affordable price. Some limits of Nexus devices almost convinced me not two buy one, but I solved these with these necessary accessories and device types. I list general categories, you research find best for your needs and wants.
No FM tuner: I found Bluetooth receivers, small, in which you plug in ear buds, standard jack; several have FM radio.
Can't remove battery. Former phones I carried two charged batteries as backups which few folk do. Now it carry a portable solar power charger.
No expandable space, no SD card. I carry a1 TB external hard drive which creates own WiFi network; it fits in my shirt pocket.
No need to give brands, now you know the devices, you can find several by a search with Ixquick or SSL Google..
Earlier I had phones with FM radio real tuners, not streaming apps. Some radio stations dont stream., plus FM tuners dont use your data plan just use battery. At first I used a mini radio but when I discoveed the Bluetooth with FM tuner I had two functions into one device.
The solar power charger I have so small I plan to buy another. You can charge in the sun and with computer USB. After full charge either way when home I leave it in window light. It's always fully charged when I leave the house. The charger has wrist strap; I hang the charger out on my pack to keep it fully charged.
The WiFi enabled 1 TB I use to stream music, video, and movies to my Nexus 4 and 7 (second generation, WiFi); it can stream to 4 devices same .
time. Google wants Nexus owners to upload their own music to Google servers then stream to Nexus device. I dont like that. I moved the Windows document folder to the D drive. I have my whole D drive on my external wifi drive. At home it is one of two al synchronized with D drive. When I travel I take one; always have out of house backup. I can access fall my files, text, audio, and visual.
The small purse size rubber bags women use for their private travel necessities I use one all charging accessories. I use the Nexus 7 cable and ac for both 4 and 7, and for solar charger.Bluetooth and external hard drive have own cables. Now my awesome 4 awesomer.
General principle: think what you need and want when you go out in home city and in travels. Carry backup Battery or charger. That's minimum.
With the undivine intervention of some folk here, their instructions, and software I have a rooted Nexus 4 and Nexus 7. Nexus 4 specs say 17 hours talk time, I get 18plus.
The removal of FM radio from smartphones it's one of the major faults of Google and reveals that they don't give a s*it about what happens outside the big markets.
My 3rd world country, obsolete and with a 9th world infrastructure can't handle streaming radio. I have 200MB/month of good internet (1Mbps). After a reach that, I have worse internet than dialup speed.
I don't know a single user of streaming radio apps here and I doubt that anyone would spend their precious data with radio.
After removing the FM radio hardware, not only Google pissed of thousands of users that loved to listen the radio but also the radio stations, that lost all these thousands of listeners.
Thanks for the tips. Will look for some bluetooth receivers

Sony Ericsson Hi-Fi Bluetooth Stereo Headset with FM Radio and the NoiseHush NS560-11977 Clip-on Bluetooth Stereo Headset without FM radio. They are small enough so I have the second as backup. Both good for music from devices; I use the NoiseHush when I listen to music from device or Seagate drive. Both easy for phone calls. Hang up and music continues. Often wear Bluetooth, sit on front porch listen to music, my device inside the house.
The Sony Ericsson can connect to two Bluetooth enabled devices so you and friend can listen to the same music.. I prefer the Bluetooth you plug in standard ear bud. If you check Amazon and like stores you will find a fairly wide choice of devices. I'd rather folk research for own purchases. You know your price range, how you use it, where and when. I am a bicycle tourist, so size and weight important. A gram or two may seem unimportant, but when you're carrying cooking and camping gear, plus digital and other items needed such as tools it's important. I carry a max of 18 kilos in addition to my weight.
I remember when I carried a laptop, sometimes total of gear in panniers and handlebar bag 22 kilos, sometimes more. Pedal a hundred miles in a day with 22 k. Now my Nexus 4 and 7 have replaced my laptop for travel.
May as well detail what I use. I recommend them only for myself. You research and if possible see the item in a store even though you plan to buy them online. I carry the Seagate Wireless Plus 1TB with my whole D drive on it; it has all my documents, audio and visual files. The drive produces own wifi, with encryption. There are other brands, but price always an issue with me.
There is a wide choice of chargers. I have Opteka BP-SC6000 Ultra High Capacity (6000mAh) Backup Battery Solar Charger with Faster Charging EcoPanel (2013 Model) I got last years model because 1, I dont feel need to get latest if an older model works, 2, older models have more users to tell how well it works.
I had planned to keep my Nexus to a few years short of forever, but decided to get Nexus 5 end of year because it has LTE. I will keep the 4 as backup.
Camping teaches redundancy, backup. I carry an older dumbphone in case something happens to primary. I carry two Bluetooth, only one with FM (FM for fun not necessity; I carry them in plastic pill bottles to protect them along with cable), I will carry two chargers soon, ordered second today, and the Seagate drive. I carry all charging gear in one of the rubber bags women use for some of privy items. It helps I rooted Nexus 4 and 7 get couple hours more by use of Elixir2 widget toggles to toggle the CPU governors ( When not using much, Power saver, moderate use, Ondemand, and rarely Performance, but sometimes multitasking it's needed), toggling off and on Bluetooth, wifi, synch, nfc, screen timeout, screen brightness, Location, and GPS. Push near 19 hours, could get more if didn't keep Google Plus and Facebook active.. The auto battery savers don't fit exactly anyone's usage style, but manually turning off and on manually does. Takes little time, four minutes in a day. Elixir2 replaces 8 apps; fewer apps, longer battery.
Use what i use as starting, check other brands and models; it has to fit your use style. I can fit all charging, Bluetooth, and storage in shoulder bag along with first aid kit and two Spyderco knives, Pacific Salt and Ladybug Salt.(Nitrogen steel instead of carbon; they don't rust.).
Sorry about loquacious rant, want to be thorough about this. Most discussions here are high tech, but most non devs, even some devs, want practical day solutions.
I don't root my devices to experiment with roms and other items in Android system. Since I use Nexus i don't do it to remove bloat. There is no bloat, some apps of Google I don't use. I don't play games so game controller unused. Perhaps half dozen I dont use I disable. Google does provide that option, so no going into system and changing extensions to App.bak until know system stable without the app.
Helpful to carry digital gear trousers with cargo pockets and if you do wear suspenders, shoulder bags ( I get mine in women's departments, the more Spartan women's bags so looks like any M or F style. Women's bags have better arranged pockets. Small day packs useful too. In town I just carry first aid kit, emergency kit, and digital kit and accessories in pockets I carry my Nexus in an inexpensive Think Sense case and my Nexus 7 in a wallet, fake leather, phone on right side and left side the few cards I have to carry, state ID, Medicare, credit card, AARP, private health care supplement card, and drug plan card. All other cards are saved digitally in Key Ring (loyalty cards for stores, library cards and two dozen others).
Carry spare microfiber cloths. i don't put protective plastic on either device; they have gorilla glass. I dont have any scratches. Out I keep the 4 in the wallet, got at Amazon; saw one at Target, so guess most major stores carry. Think Sense case for N 7 turns device off when closed and on when opened, has loop for stylus. Yes, I can write notes on the N 7 screen (perk of rooting).
Every decade items I carry do more, are smaller.yet I carry work knives, old fashion compass, and three ways to make fire.
Some HTC phones have radio

The removal of FM radio from smartphones it's one of the major faults of Google and reveals that they don't give a s*it about what happens outside the big markets.
My 3rd world country, obsolete and with a 9th world infrastructure can't handle streaming radio. I have 200MB/month of good internet (1Mbps). After a reach that, I have worse internet than dialup speed.
I don't know a single user of streaming radio apps here and I doubt that anyone would spend their precious data with radio.
After removing the FM radio hardware, not only Google pissed of thousands of users that loved to listen the radio but also the radio stations, that lost all these thousands of listeners.
Thanks for the tips. Will look for some bluetooth receivers

I figure that in your country Bluetooth and WiFi important technologies. I recommend the Seagate Wireless Plus; it holds a TB of data.
Google peeved me off by not having radio. They make a powerful quality phone without some carrier skin on top of Android, with apps you may not use but can't really call them bloat, plus you can go to settings, apps and disable ones you don't use.
