How to make a alarm for your outdoor grow op.
You will need a little nit of electronics know how to make this but with practice it is really easy to do.
List of Materials needed.
* Two pre-paid cell phones.(more if you are protecting more than one lot)
* A solar panel rated for your cell phones battery voltage. (radio shack)
* Some small clear speaker wire. (dollar store)
* Some spring and wood type clothes pins.
* Some 20lb. Clear fishing wire.
* Some sort of weather proof box painted camo. (I use a outdoor telephone box like the phone company puts on the side of your house)
* Some brass thumb tacks.
* A soldering iron or gun.
* A volt meter
* Several hot glue sticks
* A piece of leather about 1" by 2" square.
* Camo color spray paint.
* some 60/40 electronic grade solder (thin stuff) (Radio Shack)
How to make this wireless alarm
You can purchase pre-paid cell phones that do not have a name attached to them. It is very important the phones you buy for this are paid for with cash and no name or a false name is given. No paper trail is the key here!
Step 1
One telephone will be used for the alarm transmitter, the other will be used as the monitor. You want to disable the GPS function on the telephones so they cannot be tracked. This is done by shorting out the GPS antenna in the phone with solder. The GPS antenna looks like a small circle with a pin sticking up out of the center. A drop of solder is place in this to electrically short out the antenna and render it useless. (do this on both phones)
Step 2
Take the phone that you will be using for the alarm transmitter apart. Looking at the keypad, find the button that is used to "send" the call. Carefully solder a piece of speaker wire to each side of the switch pad located directly under the "send" button. I usually use an exacto knife and cut the send button right out of the phone and solder to the 2 sides of the switch pad, I then run my wires through the hole that is made from cutting the send button out.
This will be your trip wire. (more on that later)
Step 3
Take the charger that came with your phone and cut the power cube off of the end of the wire. Solder the solar panel to the plug portion that plugs into the phone making sure to observe proper polarity. (Check that + goes to + and - goes to - with the voltmeter.
Step 4
Using hot melt glue, fasten the solar panel to the weather proof box's exterior and fasten the phone to the interior so it dont shake around.
Step 5
Take a spring and wood type clothes pin and place 2 thumbtacks into the end that clamps shut to make a switch. Solder a long length of clear speaker wire to each of these thumbtacks. The other end of the speaker wire goes to the "Send" button wires you previously made. When the clothes pin is closed and making contact between the thumbtacks, it will make the phone's "send" button close and the phone will send the call.
Step 6
Using 20 lb. clear fishing line, tie the clothes pin switch to a tree. this tree is the same tree that you will have the weather proof box containing the phone and solar panel in.
Step 7
Tie a longer length of clear 20lb fishing line to a tree or bush that is located across the trail you are trying to protect. at the end of the fishing line nearest the clothes pin, tie on the piece of leather. Clip the leather between the thumbtacks keeping them in the open position.
Step 8
Dial on the telephone that is on the trail the number of the phone that you are using to monitor the alarm with. Leave this phone number on the display and leave the phone flipped open if it is a flip phone. (in the phone options you can set backlighting to the off position to save on battery power)
Trip your trip line and wait... Within a few seconds your phone that you are using to monitor the alarm will ring. Answer the call, and you can then listen to what is going on around your grow plot.
If everything is working well, press end call on the transmitter phone and re enter your monitor phone number again after re setting your trip line switch. You are now ready to monitor your grow plot anywhere you have cell service.
Make sure your weather proof box is well camouflaged and in direct sunlight so the battery stays fully charged. Make sure everything is wiped clean of finger prints before you leave!
