home security system based on a gprs modem

Hello, I want to develop an ASP.Net web site using VB.Net for receiving data from a device. The device will send data to the server where the website is placed. My question is: can I write my script in VB.Net for getting the values from the device and displaying the same information into the web server database and how should i do this and also i want to do this through dynamic dns...is it possible..if yes then how will be the interfacing be done ? i have the code but im confused about the interfacing part... how do i interface with the gprs modem using j2me without using a pc...i want to use it to send a sms through the gprs modem in a home security system to a predefined mobile number... thank you...

Your IMO?

I need some opinions and quick before my isp closes for today at 6. After finally being fed up with my modem disconnecting 3 times in a row whilst having my smoke/coffee this morning I finally called my isp up, said my router log says that I'm getting repetive ppp modem signals because the modem keeps disconnecting. Techy said come in and swap your modem in for one of these new ones they apparently just started distributing last week because they're starting up a digital TV service in early 2008 (modem has a 4 port ethernet switch in it for the tv set top boxes). I digress... previous history is that since I've had their service which was supposed to be 3mb (and when I saw the pamplet in the office today it's 5mb now for my service, sweet) but I only see like 1.5mb, sometimes 2mb as seen in the speedtest on their own server: Test starting... Average throughput: 1444 kilobits/sec Total Time: 26128 milliseconds Done. Test starting... Average throughput: 1455 kilobits/sec Total Time: 25932 milliseconds Done. Test starting... Average throughput: 1486 kilobits/sec Total Time: 25386 milliseconds Done. Test starting... Average throughput: 1555 kilobits/sec Total Time: 12135 milliseconds Done. Test starting... Average throughput: 1341 kilobits/sec Total Time: 14065 milliseconds Done. Test starting... Average throughput: 1114 kilobits/sec Total Time: 16929 milliseconds Done. That's only a few of them, I ran like 20 tests just to be sure there were no flukes (I ran off server sites and it was pretty much the same or slower). I had a tech guy come one time when I still had my P2 desktop going and it was doing the same thing (2 years ago?) I showed him on my computer, then he connected his laptop to my modem and on his screen it read 3000mbit/s perfectly (does that ever ever happen?). I think it was setup to do that on his computer or something. Anyways, I'm tired of this shit, new modem isn't making any differences. I was having a problem with it disconnecting, but I haven't had it hooked up long enough to find out if it's still a problem. The nice (and pretty) lady at the desk told me to call back "anytime" if it doesn't work lol. So I'm just sitting here, I still have the test window open on my laptop, should I call them up and complain some more or just forget it and get even more depressed about it?

Modem won't work in a different room?

Ok, so upstairs in the attic we have a modem and a router, the modem works fine up there and so does the router. but when i try to move my modem downstairs to my room and hook it into my cable line to play halo or host on warcraft, it won't connect to the internet. so my question is why this happens, whats the difference between my cable line and the one upstairs, and is there a way to fix this?

Clear Wireless Router/Modem

I'm thinking about subscribing to Clear Wireless. They want me to lease their router for $7 month. Anyone know if I can possibly buy one instead? Or is their equipment proprietary?  What do I buy? Where?

I have an interesting, but simple task at hand here!

I have just been given an old laptop to checkout, a Toshiba Tecra 8000 at that. It's a fairly old laptop and needless to say, I don't have a pcmcia ethernet cards, or any at all! I should try and aquire a crapload of them, wifi would be nice. Anywho, I'm stuck with a built in modem here, a 56k modem. I know, and have seen it done, that you can connect two computers that have dialup modems, together, and transfer data between them, and possibly share an internet connection?? I've done a bit of googling but so far all I found was about connecting two windows 98 computers together. I'm currently installing a slipstreamed version of xp onto this laptop and I have xp on here, where should I try starting with this?? I need to get an internet connection on here somehow.

Repurpose parts

In the last 6 months, I had a 40" hd tv, a modem, a 27" monitor and a laptop  all quit on me for various reasons.  I'm wondering if I take them apart if there are any parts that are worth salvaging.  I have only a basic understanding of electronics but love to tinker and want to take up arduino projects.  What would you salvage if it were you?

Ethernet cable

I have broadband. I'm trying to set up a second network. The first one has a modem and a router. My second network just has a router so far. Since I'm subscribing for the internet, can I make an ethernet to coax cable. What I want to do is take one end of an ethernet cable and one end of a coax cable and put together. Which wires do I put on? This is probably really confusing, but this is the best way I can describe it.

Boosting broadband access from a usb modem?

How can I boost my broadband access from my usb modem? I am about 2 mi from nearest cell tower and I'm getting about 2 bars of national access to about 2 bars of broadband access (slow to medium speed). When I am in town by towers I get full 4 bars of broadband, (speed is phenomenal!) Is there anyway to boost my signal from home? Can I "ghetto" rig an antenna wire from usb modem antenna to the tv antenna on top of house? Any help appreciated... I have the USB720 modem from Verizon, and a new Dell Inspiron 1520 loaded with Windows Vista. Attached is modem specs from Verizon wireless. Thanx, The Revelator P.S. Hardline/fiber optics is not an option here, only cell phone access at house.

Internet Lag?

I've had a lot of success with questions on this site so I thought I would ask this one. My internet works fine most of the time. I have one computer that has a modem and router hooked up to it for internet. I also have another computer that is wireless in the next room over, and an xbox that can go wireless or wired (mostly wired). The wireless computer can always be connected, but the the other computer (with the modem and router) has to be disconnected if I want to play xbox online. If I don't disconnect it, I will lag all over the place while trying to play some Call Of Duty on xbox. Yet the wireless computer doesn't affect it what-so-ever. Does anyone have any ideas on how to fix this or why it is happening? Thanks.

Print Server

Hello, I have a apple mac PowerBook G4 that connects wireless to our 4-port adsl modem which the PC connects to as well. I was recently tiding out the box of cables and modems and stuff. I found our old adsl modem it just has a power port a telephone port and an Ethernet port and a usb port. I also have a sub wireless adapter(plug in to a PC and you have a wireless adapter. Is there a way to modify these items to build a print server so i can connect to it and print. I can't modify the wireless modem since thats what we use for internet.Is there a way to make one so I don't have to pay like over $50 for one I want a small device so i can make our usb printer a network one so i can print easily??

Anyone here have hyperterminal knowledge?

I was hoping someone here would possibly know about using hyperterminal in windows. The situation is: 1. I am able to connect a laptop and a desktop computer via dialup modems through a 100 foot telephone wire, and transfer files using window's xp's hyperterminal program. 2. I want to somehow bridge the ethernet connection on the desktop computer to the dialup modem, to enable me to have internet access on the laptop via internet explorer/whatever. 3. If I can connect two computers via their modems with a frickin telephone cord and send files, then I know it is possible to bridge the ethernet connection into the modem like one would bridge a wireless connection to the ethernet port of a windows xp machine so they can connect a pc to the ethernet port and use internet traffic for it. 4. I know it's simply a matter of implementing it. Anyone have any ideas?

TARDIS Console Desk/Entertainment Center/Networking Area

In a few months, I'm going to be in a new place somewhere, and have three active computers at once, not counting laptops, and the husks of old machines. I am also running out of space for all of these things. I was trying to come up with design project to one-up my other home improvement geek friends from college, and it hit me: A TARDIS Console. Take three cheapo desks, cut the surfaces in half diagonally, and remount them on a slight angle in a hexagon. Mount the computer towers on odd segments, keyboards, phone, modem, router, etc on evens, sling a monitor on one of the segments, and throw some random sci-fi crap around it. Throw a big light or something in the center, leave some cables loose everywhere, and put a layer of appropriate paint on it. Instant TARDIS console. That's the basics of it. It wouldn't take too much money, but a bit of time to do properly, especially the angled stuff. Add a little extra cash and a lot of extra time, and maybe use plexiglass and put some LED's as backlight. Put old circuit boards under the plexiglass, maybe use an old laptop with nothing but screensaver on it on one of the panels, and put some extra time into decorating and it'll look great. Maybe even build in an amp and an old Yamaha keyboard for fun. This is just some speculation and a bit of boredom on my part. I just thought I'd throw this out there.

How to make a double electric circuit?

First things first, I don't think the title is accurate for this question but anyways, We have frequent power cuts in the place where i live and this is pretty irritating as my modem wont work and i cant use the internet. So I have this backup generator and I got an extension from that to power my modem (The backup generator only powers specific lights). But, the problem i face is that every time the electricity goes, i have to manually remove the plug from the mains and plug it into the generator and vice versa when the electricity returns.  So, in a nutshell, i want to make a device which can accept both the mains and generator inputs but output only one of them at any time to the modem. Problems: If the generator switched on as soon as the mains went, it would be fine. But thats not the case. 1) As soon as the power goes, the generator takes about 2 minutes to switch on and then my modem takes about 3 minutes to reboot. 2) When the power returns, the generator stays on for about 2 minutes as well. So if I were to make the device I mentioned earlier, For 5 minutes I would have no internet (generator+modem starting times) and for 2 minutes I would get 440 volts instead of 220 which would practically kill my modem. Finally the device should have, (I think) 2 inputs. 1 output. A small battery or a capacitor(For the 2 min generator lag) A switch to automatically switch form generator to mains. So can anybody give me some ideas? If you didn't understand what i am trying to say, i can gladly rephrase. I thought of using a ups or something like that but i don't know how to provide two inputs and not kill the ups itself. Thanks!!

Mobile Solar LED marquee

I've got a feasibility question for the forum. I'm interested in prototyping an outdoor solar-powered LED marquee-display drawing messages from a modem/SIM card (and therefore updatable via SMS). The modem piece of this is certainly possible, I think I could whip this together with an arduino board if necessary.  The solar piece is questionable, given the voltage requirements of even a small LED display + modem + controller. Would love to hear people's thoughts on where to start with this.  I'm considering using the LED marquee instructable, or even creating the dot-matrix myself.  There are also hundreds of display manufacturers, so it seems like tinkering with a 12V display might be the fastest solution.  In terms of solar powered displays, however, I've found only one company doing this, and the costs are enormous.   Thanks for reading.

ESP8266 WiFi Module

You need a separate grouping for this module under Technology This is a Microprocessor running at 80Mhz to 160 Mhz  with 512 kB to 4 Mb of program memory It costs $3 and is programmed with various languages compiled to machine hex and uploaded by a variety of programs to run entirely on its own with a 3.3Volt power supply . It connects to your modem , acts as a modem , serves web pages and sends to web pages and a whole lot of other stuff I have not used yet See here in the wiki for more detail   http://www.esp8266.com/wiki/doku.php

SOLAR POWERED IP CAMERA RUN ON 3G MODEM

Hi everyone, im a new member and have a task at hand which is a puzzle to me but would probably be a breeze for u tech savvy bunch :-) Ok heres my dilemma: I have a remote location where i want to setup an IP Camera run on Solar Power. I have purchased a wireless 802.11 ip camera with pan and tilt capabilities as well as an audio in (internal mic) and an audio out (1 x audio line out interface) along with 4 alarm in and out male ports. Heres what i want to be able to do: 1. View the cam remotely via PC/Mobile Phone. 2. Utilise the Pan and Tilt capabilities 3. Have a text message/email sent to me everytime the alarm is activated/motion is detected 4. Be able to have audio in and out 5. Have the camera on standby until motion is detected 6. Have the solar power as the only source of energy for the camera and the camera to be able to run 24hrs a day (standby and in use) 7. Was also wanting the solar power to charge batteries so at night time the cam would still work or if its a cloudy day etc etc Now im thinking that i would need a modem with a sim card in it to work the internet side of things. But how would i go about getting the audio and alarm functions working? I can plug an ethernet cable into a modem and put a sim card into a modem and connect the cam and modem up to a solar power source, but where the heck do i plug the audio and alarm cables into??? In the below link theres specs on the cam as well as pics of the types of connections available on the cam. I wouldnt have a clue about Volts and Watts and amps etc so am stuck at just buying the cam which is here: http://www.aliexpress.com/fm-store/107302/211328538-491571938/Promotion-free-shipping-cctv-wirless-ip-camera-wifi-802-11-b-g-9-language-m-jpeg.html Please help ladies and gents it would be kindly appreciated. Thanking you in advance for your words of wisdom.  p.s. i have scoured the forums and google for this type of setup and have got close but need something custom for my situation and my low level of knowledge in these areas.

Super site ... but SLOW!

This is a wonderful site ... I learned how to remove rust electrically ... good stuff; however, the site is brutally slow between pages (downloading). I have high speed access via cable modem and this site is like using dial up. What's up? Is it the server? Has the site been optimized? Pictures optimized? I will continue to visit because the site and concept is strong. Thanks.

Dial-up internet server

Hi everyone, I am trying to connect my Sega Dreamcast to the internet with it's 56k modem, without using telephone lines. From what I understand, I need to connect my my Dreamcast to a tone generator, then to a USB modem plugged into a laptop with which to forward the connection over wifi. My question is: Is this is a plausible solution, and if so, could I simplify and shrink this set up. Ideally I would like to figure out if I could build a tone generator instead of buying one and how can I replace the laptop with something like a raspberry pi. I think that once I figured out how to forward the connection on my laptop, it would be fairly straightforward to do the same with a raspberry pi. I would prefer a relatively compact solution if possible. Thanks in advance for any help or thoughts.

Home made energy saver

First of all sorry for my English Its just an idea, like that "Intelligent Power Strip" but on the cheap. Use a relay powered from the PC molex (5v yellow-black), so that when you turn off your computer, it turns off, for example, the sound system, modem... connected to this. I have no experience with relays or high voltage. Anybody interested?

use a landline telephone, speakers, a mic, and a computer to go online with dial-up

Would it be possible to use a landline telephone, a computer with speakers and a microphone, and a software program to connect to the internet with dial-up? there are multiple free dial-up numbers available, so if I called with the phone, and used the computer to emulate an analog modem and listen to the response with the microphone, would I be able to get online? if so, does anything like this already exist?

I have a large CRT colour monitor, but I'm not too sure I want to take that apart.)L

Computer update......disassembled....

My computer has bit the dust (more than I expected when I opened it up), and the CMOS is completely fried...so I have disassembled it and am on the older yet, computer - another Gateway, single threaded CPU and the only port it recognizes on my DSL modem is the USB port......slowing it down EVEN FURTHER.    Time to go into debt again for a new one.....*sigh*.   But this is why I haven't been around quite as much as I normally am.

test RJ45Cat5 to USB Female

I'm new to this forum. I need some instructions. I have an RJ45-cat5 male to USB female connector that I bought for 3 bucks. I've tried using it to connect my HP 1050 j410 USB printer to my Linksys WRT54GS (wireless) router so I can have a network printer. (The Desktop is directly wired to the cable modem and the to the router.) It doesn't work, but I don't know if it's the connector itself, or that the printer will not communicate with the router, directly. Is there a way to test the connector with another piece of hardware to determine whether the connector is actually any good? BTW.. I can't determine from HP, whether the 1050 j410 USB printer can become a network printer. Should I just go buy a USB print server for 20 bucks, or whatever? I'm using an Ubuntu 10.04 LTS Desktop with AMD-64 processor. Thanks to you for the best advice. Shobuz99

My Laptop's wifi Has Low Connectivity

I have an HP Windows 8 laptop that used to have fast internet. But for a while now, it's only had 2-3, or sometimes even 1 bar. I am using my neighbors internet right now. My sister also has a windows 8 laptop, and she uses the same internet I do. But she has great internet, mostly full bars. I know my laptop is capable of having fast speed too, I just don't know how. I think there is a setting or program stopping it from having better connects. I just want to know if there is a way fix the problem without messing with the modem. One last thing, when the laptop first starts up, the internet is at full bars about 2 seconds, then goes down to about two. Any way I can fix this issue?

Landline and mini speaker & microphone : can one use bluetooth mini speakers ?

Hello,Is it possible to use one of those small bluetooth speaker + microphone sold everywhere with a corded phone (cordless but wired to rj11 modem-routeur) to achieve some kind of JABRA-like system ?This is intended for me (light hearing impairement) and my parents.Of course the Bluetooth would not be used as bluetooth but as a "wired" speaker+mic to the phone base (with 3.5mm audio cable as for headset used by gamers..The idea is to get a louder volume than the handset or base of a corded phone can provide.and the problem of sound quality + cuts that arise from this mode of use (listener cans speak but with a delay ...) Please, don't answer me to buy "Jabra" or buy "amplified" dect phone.Just in case, I dream of a mini speaker not bigger than a glass o water connected with a lapel microphone (or replacing the microphone + speaker of my GIGASET handset ...)Any answer and/or suggestion would be appreciated.

I`m building burglar alarm with sms alert with ir throughbeam sensors I have a problem with the code gsm modem sending sms even when the throughbeam is not broken Can please anyone help me with this code: #include "SIM900.h" #include #include "sms.h" #include SMSGSM sms; String smsText = "INTRUDER "; boolean started = true; char sms_text[160]; int ledPin = 13; int SENSORPin = 4; int val = HIGH; #define SENSORPIN 4 // variables will change: int sensorState = 0, lastState=0; void setup() {   pinMode (ledPin, OUTPUT);    pinMode(SENSORPIN, INPUT);       digitalWrite(SENSORPIN, HIGH); // turn on the pullup   Serial.begin(9600);   if (gsm.begin(9600))   {     Serial.println("\nstatus=READY");     started = true;   }   else     Serial.println("\nstatus=IDLE"); } void loop () {   val = digitalRead(SENSORPin);   digitalWrite(ledPin, val);   if (val == 1)   {     Serial.println();     smsText = smsText;     smsText.toCharArray(sms_text, 160);     sms.SendSMS("0701548869", sms_text);     String smsText = "intruder ";    for(;;){ /*empty*/ }   } } Can anybody plz help me

What Should I do with the things that I have?

So I was cleaning some stuff out tonight and I found a bunch of stuff I really have no use for I found: - an external CD/DVD dual layer burner - 4 output VGA splitter - firewire PCI card - 56k fax modem card - old keyboard - a distortion pedal (guitar pedal) - 3 various capacity harddrives - knock off ipod nano (broken) - old comp speakers w/oldschool mini - subwoofer - acoustic guitar soundhole pick-up - crappy digital camera with IR filter removed - unused web cam - huge assortment of cords - USB wall charger (small box with outlet prongs and female usb input) can anyone think of any quality usable projects I could make with any or all of this stuff? (I might be willing to part with the more expensive items.....EX. Burner or VGA splitter for shipping and an super extremely discounted purchase price...... I'm to lazy to Ebay any of it)

Network connected telephone answering machine

I was hoping that SOMEONE made a telephone answering machine with a network connection so that it would do its thing like any other digital answering machine but the messages could be managed over my network. So I did a google search and it seems others have also been interested in such a thing - albeit the most recent queries being at least a year old. The answers were - "I already have that on Vonage" - sorry - don't want voip!! And various programs that would let your computer, with voice modem, do that including linux programs. Well - I don't have a full blown computer on all the time and am not likely to. And so I thought - how about a small computer - but don't have one - couldn't think of one ... And then I thought ..... Raspberry PI!!?? So small and low power that it could even be put in an old answering machine case and low power draw. Does anyone think its enough computer to do this?  Anyone up to inventing one?

Arduino Mega with Sim900

Recently I bought Sim900a module and Arduino Mega 2560 to run my old code for sending sms and call, but now there is a problem as I am unable to send sms or either call, my code is attached below. #include SoftwareSerial gsm(2,3); void setup() { gsm.begin(9600); // Setting the baud rate of GSM Module Serial.begin(9600); // Setting the baud rate of Serial Monitor (Arduino) delay(100); } void loop() { if (Serial.available()>0) switch(Serial.read()) { case 's': Send(); break; case 'r': Recieve(); break; case 'S': Send(); break; case 'R': Recieve(); break; } if (gsm.available()>0) Serial.write(gsm.read()); } void Send() { Serial.print("Sending"); gsm.println("AT+CMGF=1"); delay(1000); gsm.println("AT+CMGS=\"+xxxxxxxxxxxx\"\r"); // Replace x with mobile number delay(1000); gsm.println("Hello I am GSM modem!!!");// The SMS text you want to send delay(100); gsm.println((char)26); // ASCII code of CTRL+Z delay(1000); } void Recieve() { Serial.print("Receiving"); gsm.println("AT+CNMI=2,2,0,0,0"); // AT Command to receive a live SMS delay(1000); }

Wardrivers :/

Last night while collecting the mail, I noticed a glow coming from inside a car. The guy was sitting in the drivers seat with a laptop, and had a small antenna stuck on the roof of the car. He was running Ubuntu and was trying to connect into my wireless network. (WPA2 thankfully). I could even make out my SSID. I thought of knocking on the window, but I had a better idea. Went back inside and disconnected the modem from the router (just in case), and booted up a LiveCD of Puppy Linux. I created a ad-hoc wireless network as bait and waited. 5 minutes later someone was connected. The user connected was Darren-Lap. I got his IP address and managed to SSH into his laptop without any password prompts. Quick Google to see if I could send him any messages through the Terminal. Found a method and sent him a message saying if he didn't leave in 5 minutes there would be consequences. His reply: "F**K YOU! Suddenly the firewall was getting a lot of hits.  A simple "sudo rm -rf /" command sorted him out. (http://is.gd/fE7cL - demonstration) So here's a tip: Try to hack into my network, and be prepared to lose. :)

Samsung lcd bad cap problems

Hey guys, recently I scored a Samsung 943nw monitor from my friend who says it's broken. So i thought, why not try repair it? Upon opening the lcd monitor up, I can see that the caps were bulging, samwha brand. The infected caps were three 25v 820µF and two 10v 1000µF. I went and sourced the caps from a couple of devices (a modem, and a power supply) When I turned the lcd on, the led was blinking. After the repair(with my crappy soldering skills), the monitor turned on, but not the backlight. I figured that the cc backlight inverter was spoiled. Then, after a probing at the components, I reset the monitor in hopes that the inverter would work. Instead, now the monitor showed no signs of life. Probing again showed that the 5v rail was 8.45v and 15v rail was 4.5v and 3.3v was ov. I still can't find the problem after hours of searching. (and a fatal electrocution from the mains input cap). Could it be my bad soldering, parts or some transistor problem? DId I also accidentally fry the image processing module?
