- This is an infrared transmitter I built that emulates emergency vehicles when waiting at stopped lights. The i.r. l.e.d.'s strobe at 14 Hz. Comment for any questions.
This is illegal and only used for educational purposes
Nice project... don't get in trouble with it...
That’s awesome man! Keep up the work like this and you’ll be a very successful adult. Just be careful!
Nice project, I remember back in 04 when everyone on the internet was trying to build an mirt. I still have mine from way back
Do you sell the directions and schematics ?
555 timer circuit and a variable resistor, Maybe?
When I'm late I need this
Highly illegal but also higly sweet
Just put a blob of flat black paint over the LDR, no need to short out the collector and emitter
What about using a timing light and revving the motor to 1680 rpm on a typical or 840 on a lost spark ignition engine? 14 hz=840 fpm. A spark plug normally fires every other revolution, so 840*2=1680rpm.
Benevolent Highwayman why not send a probe to space and build a complicated radar array to flash these leds at 14 Hz from the space?
@@whatever7338 why not just run the red light?
I think it's awesome. Would love to brain storm with you some time. This tied in with spectrum jammer and EMP I've been researching would make you a rather dangerous person. Great work
They changed the signal to 10hz.....heres the code for arduino
const int ledPin = 13; // LED connected to digital pin 13
const int interval = 50; // Interval in milliseconds for 10 Hz (100 ms cycle, 50 ms on, 50 ms off)
void setup() {
pinMode(ledPin, OUTPUT); // Set the digital pin as output
}
void loop() {
digitalWrite(ledPin, HIGH); // Turn the LED on
delay(interval); // Wait for 50 ms
digitalWrite(ledPin, LOW); // Turn the LED off
delay(interval); // Wait for another 50 ms
}
You should sell these as kits. Nothing illegal about selling the parts. Very ingenious. I would buy one. Message me. Even if you just want to sell the diagram and specs. Thanks
@@motosk8er2 I am interested. Please let me know how I can get the schematic and code.
Thank You
@@ocsrc It's illegal. _"In the mid-2000s, you could buy MIRTs openly on eBay, then in August 2005, the Safe, Accountable, Flexible, Efficient Transportation Equity Act was passed. It set a minimum sentence of six months in prison for anyone using the devices, and a year in prison for anyone selling the devices."_
Can you build me one? How much would you want for it?
you can do the same thing with a much smaller package and less components by using the 555 timer IC, a couple resistors and a capacitor for frequency with signal into a mosfet or maybe even a few stacked npn2222s as the driver. those 555s are cheap and easy little ICs. No need for fancy interface.
Can you build me one?
I could but this is felony to use.
You could use a 555. How would you calibrate it?
Can I get a detailed list of everything needed?
@@studkickass513 the 555 is extremely precise.. used as a flip flop comparitor you can get the formula from its datasheet.. its as simple as the right resistor and capacitor to set your frequency, duty cycle and pulse width.
anyone who is making these heads up that they only work if the intersection or light in question has a receiver for the transmitter this system isn't supported in all cities [educational]
Schematics please!!
I had blue strobes behind the grille of my - wait or it, Ford Crapi (Ok, 'Capri') 3.0s, but took them out as I didn't fancy losing my licence. Fun for a while!
Nerd! Lol but honestly it's pretty amazing what people can create these days. Cool build.
Does it work? Gonna try makin one with my audrino for the hell of it.
This doesn't work anywhere anymore. Most departments switched to the Omni system. Dispatches are in control of traffic lights now via a city WAN network. This would only work in rurual areas.
My company manufactures a GPS preemption system that compares in COST to the optical systems collisioncontrol.net/PreemptionSystems/ . When you said Omni system I assume you mean GPS system or Multi mode which is a system that works with existing optical systems and GPS. Our system is a multi-mode system. If a department has existing optical they can start replacing units with our system as an upgrade strategy. Their existing optical systems will still work and of course our GPS system will work. I can confirm what convictcreations said below. The optical systems are not only still in USE today in many large cities the system is still SOLD today simply because the cost of other GPS system is very high. Often in the 12 to 15k per intersection range. Although some cities get a grant, there are only so many grants to go around. Then there are other costs as well with GPS systems from other companies. Some use wifi radio which is low range (4 tenths of a mile without obstructions factored) so then the city has to buy range extenders etc.
@Cytranic - yeah... ur way wrong dude... u sound like a salty troll... I’m on the other side of the river from manhattan.... OMNI costs a ton and it’s only used on the major roadways that are near terror watch list sites like MetLife Stadium, American Dream, etc.... you’re clearly basing your DEFINITIVE statement on whatever went on in your little bubble of the country because we are among the busiest first responders in the nation and we HARDLY have MIRT.... In fact, I believe that only the FD has MIRT in my area and the sensors are again only on select few busy congested intersections.. The cops aren’t trusted enough apparently because I’ve been one here since 2002 and I had to beg for a damn traffic box key last year because all they ever gave me was the skeleton key to the OLD SCHOOL boxes (which are STILL IN USE on almost ALL intersections that are just off the main roadways)
There are schematics and code for this elsewhere everyone... I just don’t wanna be responsible for being the one who points you there... git me? ✌️
$200 + your expense for parts sound fair?
Bro that's badass! Your like a living watch dogs characters!
How are you powering the arduino and the lights with the same battery? Also, how did you bypass the photoresistor?
Do they make one that changes them from green to red ?
I mean it does for the perpendicular direction
Hey I have a question
Have you tested it say on a radar detector with emergency vehicle response? My code always seems too glitchy to make my radar detector go off. My dad has a real one on his response truck and it goes off for that every time. I also noticed that I used white LEDs... Probably a bad idea.
I have tested it by measuring the cycles per second when filming it when turned on and then slowing it down and counting its strobes per seconds. The code is extremely simple and has few "moving parts" so there's not much room for error, however I would make sure you have a balanced power supply and many L.E.D.'s before expecting any real results.
White L.E.D.'s will not work, only infrared will.
@@Belofsky1 How can i get the schematic and a parts list. I would really appreciate it and would be willing to pay you for it.
@@motosk8er2 just let me know how i can pay you and i love to have the plans for that . I we ill even throw in a little extra $$$$ if you can get back to me soon my email is dbcoopermastermind@gmail.com
Let me knoe ASAP thank you
@@convictcreations it worked because xenon lamp emits wide array of colors UV included, leds are always tuned to certain wavelength
Instructions?
Can you send full schematic and parts list plus code?
So how u make it?
Altering traffic patterns is highly illegal in the United State. You use that, the cameras catch your plates, some nice LEO show up at your door with some shiny bracelets.
Here where I live they actually use a much simpler system and if you flash your high beams 10 * at the intersection there's some sort of camera that picks that up and changes the lights to Green
Up in New York where I came from they had the mirt system and it was encrypted so that you had to have the specific pattern that the emergency vehicles had to make the lights change
And each Town had their own encryption method or pattern so that going from one town to another the vehicles could not change the lights in the other town which turned into problems and some spectacular crashes when they were chasing people from one town to another
I don't know if they ever came up with a unified encryption but I remember seeing a three-car pile-up at a busy intersection where three emergency vehicles came from three different directions and managed to t-bone one and then the other as well as about 20 cars I think someone actually died in that crash it was pretty spectacular and that was back in the days when these systems were first being implemented and my town spent 50 million dollars to put them in at taxpayers expense because the traffic was so congested it took 10 minutes to get 1 mile on an average day
Hear the strobe lights that they use on the standard lights behind the headlight that are white not the red and blue ones but they have white ones that flashes well and they're visible and I guess it's 10 flashes a second and it triggers the lights to go green and they've had this system for a very long time I remember seeing it down here in the 80s before I moved and coming back they still have the same exact system all these years later which it must work for them so they don't spend money to upgrade it but they did spend about 400 million putting in a 700 megahertz p25 Phase 2 simulcast radio system which caused everybody's taxes to jump about $1,000 a year to pay the loan that they floated
Many times they have to go back to the analog system from 30 years ago because the p25 simulcast has a lot of trouble with the terrain and the digital signal breaks up
I have a straight shot with a link from my house to the tower 1 mile away and I see the dispatch comes through at 100% because it's a direct wire to the transmitter but for the mobile units they only get about 75% and for the Portables it's about 30% so it's really not anywhere near as good as the old analog system which I actually bought all the radios that the town sold when they switched over for a buck apiece and these things cost to Grand back when they bought them so now I have Stacks and stacks of radios that I'm trying to sell that still work really well for being 30 years old
good thing they need to catch you in the act and have no authority if they cant identify who it was 🤷♂️
Wrong
@@roundstone2020 show me where any of this is written into law about this
REE YOU HAVE TO ASK DADDY GOVERNMENT FOR PERMISSION REEE. I LOVE BOOT POLISH!
Nice project..but no proof 😂
Does the sensor like see the flashing light? Do you have to aim it at the sensor? How does it work? Why isn’t it more like a remote controller without light
The IR sensors on red lights see the flashing light at specifically at a rate of 14Hz, which then sends a signal for the light to turn green. However some intersections are equipped with cameras and use some other methods to determine when and who used the preemptive system so I wouldn't recommend to anyone that they try and replicate this. (Preemptive system refers to the ability to use this in emergency situations)
MentalTacoDog that’s why I would only use it on the light leaving my neighborhood which doesn’t have a camera
Did you ever get this to work? I built almost the same thing but between the pulse width and the brightness of the LED array, I can't get it to work. Currently I'm waiting on a 30W LED array which I will be over-driving with a 20v power supply. If this isn't bright enough, I'm not sure what else would be :)
Richard Driskill big cities use the Omni system and it's controlled by data networks. Source, my brother is a firefighter.
I want to purchase the schematic for it anyone have one that will work
Can I buy this from you
I just set mine up and it doesn't seem to be working. The one I got is called a Nova Preemption Strobe from Strobes N More. I was told that it might need to be programmed with a particular code. Anybody know anything about this?
@@convictcreations Google shows nothing for code zero, do you have a link?
What wavelength do these use?
VB YTP Using “Wavelength=Velocity/Frequnecy” I’m getting 21413747 m for the wavelength of all LED’s operating at 14hz.
However this is for the strobe, not the actual LED’s that operate at a different frequency. I’m just going to assume you were referring to the strobe’s frequency.
I was referring to the LED frequency, but wavelength is typically used for IR LEDs
I scavenged them from an infrared security camera lighting system so I’d assume the wavelength would be nominal for infrared LED’s.
Haha that's cool! How did you program it to flash them at 14Hz? They just flash on and off every 71ms (14Hz)?
And do you really need so many IR led's? Are they all connected in parallel?
Also what's the wavelength of the LED's
I heard to both use 850 & 940 nm iR’s, one’s more visible in the human light spectrum… also, you gotta get the fatty Stronger emitters if you’re gonna make a DIY MIRT.
That one

I have boxes of the original MIRTS. They are not illegal like everyone says... Using them is a different story.
@@roundstone2020 I'll buy one to look at for educational purposes only.
Do they work in uk?
MyTravelAdventures Any traffic lights with infrared recievers should work.
Probably not, the police can legally go through a red light, as long as they got the blue sirens on.
@@ChristopherJohnJackson huh?
Are you interested in selling this beautiful invention
