Two stakes in the ground are another solution, but if you’re trying to raise your trip wire to a foot of height, you’ll need long and large stakes deeply imbedded in the ground. There are also some fairly easy do-it-yourself alarm systems that you can put up just about anywhere. YouTube is full of DIY project tutorials on how to make simple tripwire systems out of a laser pointer. These simpler systems will require a battery to power them unless you want to plug them in. They are created by setting up the laser pointer and reflecting it against a light sensor. This sensor is hooked up to a circuit board of some kind, which then tells the computer that has been coded to do something (whether that is to sound a buzzer or to send you a text message). When the beam of the laser pointer is broken, (the equivalent of someone tripping over a wire) a switch will flip on the circuit board, which will then trigger the computerized response, notifying you of any intruders in the area. when turning off the light (the voltage drop on R3 increases), i.e. R = 1, S = 1 - the forbidden state for the RS-flip-flop. We might as well start with the wire. There are a variety of options. Usually, the wire or cord is low-profile and hard to see. It also needs to be relatively strong. If someone or something walks through the wire or cord and it easily breaks, little is accomplished except alerting the intruder to the fact that you’ve setup some trip wires. I'm just getting into electronics and this looks like the perfect project to start me off. I just wondered if there is a way to run this circuit on a 9v or 12v supply? Rather than add one of those tiny buzzers id like to add a 12v siren with flashing light on the outside of my house.

As a trip wire, they’re mostly designed to deter wild animals, but the people who sell them offer all sorts of reasons to use them. You’ll certainly hear it, and it will scare most anyone and anything away. Monofilament is an excellent trip wire source. It’s hard to see during the day and totally invisible at night. The key is to have a strong enough weight test to activate the noise without breaking. It can be used in most any trip wire setup in any location. In countries ravaged by civil wars and civil unrest, no night is safe and trip wires are sometimes used to at least alert the local population if a covert threat is approaching. Select the drop-down menu next to Direction to choose if the IVS alarm is triggered in both directions (Both) or just one direction ("A To B" or "B To A")
Who is this technology for?
You don’t want to test your popper trip wire or you’ll have to retie another one. If you want to test the distance and whether or not you’ll hear it, have someone in camp or in the house listen while you pull a spare popper. If they don’t hear it, move the trip wire closer. Don’t be tempted to add multiple poppers to the same trip wire. What will most likely happen is that one popper will trip, leaving any others unexploded. This setup uses a white length of electrical wire attached with overlapping loops through two holes in the top of a can painted white. Obviously, it’s a winter trip wire and it uses marbles or pebbles to create the alarm. The overlap of the wires causes the can to shake and rattle more than a conventional wire or line passing through the holes. So what does this little anecdote have to do with a trip wire alarm system? Honestly, more than you'd think. My brother had figured out a system (albeit using his body rather than a real wire) that has been around for over a hundred years now. He was using his body to topple me over, thus incapacitating me and making it difficult for me to get up right after I fell. All he was missing was an alarm. Although he probably didn’t want an alarm, or he would have gotten in trouble with mom.

We recommend you sign up to our Newsletter and/or SMS to get notified when we ship internationally. The idea of most trip wires is to make a lot of noise when someone trips over the wire. Noise makers vary depending on what you have available or may have bought in advance. We’re going to assume your situation caught you a bit by surprise and that you have to improvise from available materials. switch for a trap/cage door? The trigger/release could possibly be something that would change the polarity on a magnet and would hold open a small Monofilament fishing line. 50 pound test or higher is best, but any weight test will do if it’s all you have on hand. You could even double or triple up the monofilament if you’re worried it will break or snap. Stretch it tight to another tree trunk, branch, sapling, or stake and wrap and knot with another improved clinch knot and pull light.
The batteries are mounted in individual AA battery holders. The three battery holders are soldered together in series and the end leads are soldered to the circuit board. Today, trip wire alarms are much more technologically advanced. Many systems incorporate laser technology that will sound an alarm if someone were to step across the laser. That’s right, you read that correctly. Lasers. Not exactly like the rotating lasers in Get Smart or the James Bond films, because these laser systems are invisible. No glowy red lines crisscrossing all over your yard and house, just simple, understated, invisible technology. Test your bungee trip wire again with someone in camp or in the house and ask them if they can hear the cans? If not, move the trip wire closer or add some more cans. Not yet. We are very close to getting our product available to to the rest of the world. Due to the nature of our product, it takes more time to get approved. If it makes noise, it’ll work on a trip wire. The only challenge is figuring out how to trigger the noise. Things like sirens need power, but if you’re handy with a little wiring, you can make a trip-switch to set off the siren.
