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...

Can You use a GPRS with a landline phone?

I have wanted to this but can't find info But what I wanted to do was to set up and Arduino with a GPRS shield but instead of it being the phone I wanted to have it hook up to an old rotary dial phone and have it work like it's plugged into the wall and the arduino/shield would be in a box but the question remains, can that be done or is it not possible?

Ground Penetrating Gadget

Hello, out there, I would like to find how to build a ground penetrating gadget. I think there are a lot of 'us' would like to have something that can 'peek' underneath the surface of the ground, not necessary very deep. For example, such a gadget that can help fossil hunting tremandously. And it does NOT have to go all the way to Ground Penetrating Radar. As long as it can detect the differences between the matrix and interested object up to say 50 cm in depth, it will be good enough. And it doesn't matter what physical principle is used: GPR, ultrasound, electrical resistance or capacitance, ... (whatever). What I have in mind in such gadget would be tied to one of the shoes (so, it must be very light weight), using wifi to transmit the signal to iPad/iPhone so that the user can just walk and know the place to dig. Any help or comment will be greatly appreciated.

High Altitude Balloon

Hello guys, I have recently started working on a high altitude balloon project. I am planing on making a balloon that will go up to 100k ft and while it is travailing up to that altitude it will be snapping pictures and taking videos of the sky.  I am publishing all the updates related to this project on a project dedicated website www.AggieSpaceProgram.com . However after i am done i will be also making a very deatailed instructable on it so others may fallow in my foot steps. I just wanted to share my project with the instructables community, L4I

Ground Penetrating Radar

I am looking for any information regarding Ground Penetrating Radar (or GPR). I am a newbie to this type of tech and was hoping the someone may know of a basic reference manual or other sources that could contribute to building one from the ground up at reasonably little cost. Also, I am looking specifically for something in the high frequency range - good resolution at minimal depth. The hardware side is more important although any advice/resources on the software to interprete the data wouldn't hurt. Thanks in advance! By the way, my user name(just created and second guessed) has nothing to do with being dug on digg, or anything to do with digg for that matter - just thought it had a nice ring to it... Thanks!

Arduino and GPS data logging - code/hardwire glitch

I've followed Gabriella Levine's code using an LS20031 GPS module. A couple of problems: 1. Can I run the SD card off the 3.3V arduino lead rather than using 5V and stepping it down (as one sketch suggested using a resister array)? 2. I've attached an image of what my Serial Monitor is reading and can't get it to align properly, feed consistently, etc. I've tried changing many aspects of the code, reverting back to original after each. Nothing seems to help. The only time I get a stream of NMEA data is when I reverse the Tx and Rx at the Arduino and hold the reset button - then it pours in. 3. I checked with my local hacker group last night but not too many are working on GPS projects - I've pasted my code below. If someone can confirm the wiring of this, that would be great. I'm still early in my Arduino project work. I made some notes in the code so you can see where I think the problems are.  4. Could it be that the baud rate (57,600) of the LS20031 is just too high? Milton //Gabriella Levine - starting code //https://www.instructables.com/id/Track-your-route-using-arduino-microSD-card-shi/#step1 //code (no shield, just a MicroSD like mine, different GPS, same idea with some good additional ideas // original code source: https://github.com/Protei/Protei-005-6/blob/master/GPS_GPRMCstringsParsed_toSD/GPS_GPRMCstringsParsed_toSD.pe //See website saved in folder for instructions on wiring - she has clear, direct approaches - very good. //My LS20031 GPS module (marked 1590R-A over a P) runs at a baud rate of 57600 (bytes per second) #include #include #include //this seems to be in the library but unclear - why isn't it orange like the others?
