OptiCom 3M Preemption Sensor - Flashlight and Flipper Zero control Traffic Light MIRT.
Вставка
- Опубліковано 25 сер 2024
- I finally got my hands on an actual OptiCom 3M Preemption Sensor. In this video I will do a teardown & revers-engineering of an actual OptiCom. I tested it against many different types of light signals including my now famous Flipper IR Array. I also introduce a new device, a modified $12 tactical flashlight, that can also trigger an OptiCom 3M Preemption Sensor. Business enquiries please contact me here: contact@commandergateway.com
You've inspired me to stop playing video games and keep playing with my flipper zero. I grabbed the Ultimate Kali Linux Guide a few months ago and have been coaching friends through it. Keep up the great work as this will definitely motivate others to take up the craft!
@@peterfairlie2296 Oh I've been running it for a few years on my Dell R410 with 2x8 core CPUs and 96 GBs of RAM.
I'm more blown away by these seemingly innocuous attack vectors that lay in plain sight for the public.
all the kali/blackarch/etc. shit is useless. a decent setup that you trust and a good reverse engineering suite will take you farther than some wannabe-1337 distro ever could.
No offense, but you're flat out wrong. Kali covers the most distance post install. Most other distros still need hping3 installed and I just don't think I should have to do that out of the box. Especially when I can just spin up a VM on one of my many servers. Heck, I''ve given it the rails on a dual Xeon pizza box before.
Coming from a guy who's been using CentOS in the field for more than 150 clients for the past 6 years.
Time = money and some of us are already making money with this wannabe-1337 distro that you have some sort of personal vendetta for.
Either way, I've gotta get back to counting my cash like Scrooge Mcduck 💰💰💰💰💰
@@userhandle3378 >Kali covers the most distance post install
you've been spinning up VMs for six years and you can't put together a custom image that covers the /entire/ distance?
@@stdcall please reread my post before I ask about your reading comprehension skills, I don't answer the same question twice
That's impressive... actual opticoms don't ever change lights that fast, although your set-up doesn't have to account for traffic.
I like the idea of a flashlight...I need one!
The flashlight mod is hilarious
@@peterfairlie2296 cars come conveniently with built in flashlights, 2 of them
@@GigaVids hit em at the CAN and modulate em too 😂
@@GeoffereyEakinsTech LMAO yes
what flashlight from amazon?? model?
How did you do the flashlight mod? Any reference guide ? Amazing work!
That is insane! That's so cool. I get mine coming soon!
did it come in yet?
What's really funny. There was a guy that had a really old car and he wanted to put LED bulbs in. The bulbs called for some kind of circuitry to be connected between them and the headlight connectors to smooth out the signal coming to the bulbs so they didn't flicker. He use the electronics on the low beams. But he didn't put them in his high beams. Not all the time. But sometimes when he flashes his headlights. He can trigger the stoplights in our town. He doesn't abuse it but he figured it out one day he was driving at night and he flashed somebody to let them know they could switch lanes. traffic lights in my area have a bright light that turns on when they're triggered. He noticed that the stop light in front of him turned its light on and turned green. He then described to me how he went around town and randomly did it to try and prove himself wrong. He said it only works like 2 out of five times but every time it works it works exactly like the cops.
Apparently, here in Australia, we have the same things on our traffic lights, except they look like upside down cones on the top of the poles.
I've been driving trucks for almost 30 years and the strange thing is, whenever I see an emergency vehicle approach a red light, NEVER have I seen the light go green. Instead the emergency vehicle slows down, weaves through traffic, mounts a curb if need be and then blasts its horns and sirens as it carefully goes through a red light.
Don't think those are opticons. It's a camera that's scanning the intersection for traffic still in the middle and will hold the current light phase.
I have one of these in my car and it works great. A word of warning! I never use my on red light. I only use my to keep a green light, green. For example. If I'm approaching an intersection and the light's green. I use my opticom to keep the light green until I get through the intersection, then turn it off. NEVER, EVER USE AN OPTICOM DEVICE ON A RED LIGHT! THAT A SUREFIRE WAY TO GET BUSTED!
If an intersection has any sort of photographic camera (CCTV, traffic analytics, speed camera, etc) you should even steer clear of keeping the green light enabled. I think there are also opticom units with integrated cameras that can be configured to snap a photo to associate with each logged event.
could you show us how to modify the flashlight?
Can you make a how to for the flipper? Soo cool all vids!!!
got it 14 hz modulation! :) thank you so much. I wish I could modify a flashlight like you do. you should sell them
He shouldn't and judging by which comments it looks like he's not responding to I don't think he's going to. It's a federal offense and I'm guessing most states have laws against it too.
18 U.S. Code § 39 - Traffic signal preemption transmitters
@@zachbrenner9959 you should grow up and be a man
@@zachbrenner9959 Only he lives in Canada, genius...
@Peter Fairlie - What's to stop you from doing this with LED headlights?
well i guess u could modify them to flash that fast...
24VDC and you have the Model 721 the blue and bare should be joined at the cabinet.
Any ideas on how the radio shack strobe light is timed? If it's just a pot in front of a cap or several, would reducing the cap values to half of the original not give you double the frequency, which you then attenuate slightly to bring the duty cycle down to 14.035Hz, or thereabouts?
It's a really simple circuit, and it skips beats. I'll take it apart and show you (faster than finding my old photos)
Where is the signal processor? Can you show that in the frame while you causing a preemption call?
Love you video still I have all the parts just need to put together for ir flash flipperzero
Most Opticom systems are encrypted now, so this hack wont work across different systems unless you decrypt the exact pattern for each system. Also, Federal Signal now produces the Opticom, 3M sold it over a decade ago. Very cool hack though!
How to modife the flashlight
i've triggered opticom with highbeams, but the timing is really hard to do.
underrated comment
Ingenious
please release a tutorial for the love of the flipper gods
Great video! I have some Opticom stuff myself!
@@peterfairlie2296 thanks dude! If you have any questions or need any extra Opticom gear, just shoot me an email anytime!
@@andreaiannaccone5640 I do have a copy of GTT OnSite for the GPS units.
@@andreaiannaccone5640 for the optical or GPS?
PWM is clever, how did you vary the frequency on the tac light?
What controller do you use to hook the opticom too? And what controller do you use for the traffic light? I have a galak controller and been wanting a optcom sensor for my two lights 😊
I assume this won't work in EU right, because emergency vehicles doesn't need green light to cross the intersection here :)
Do you have a link to where you got the flashlight? Or did you mod it? Also would be interested in the other light changing sensor
OH look......Squirrel 🐿 4:27
That inferred light in a stroblight box hook up to a flipper o is a bigger flashlight LoL👍✌️💯🛠️🤔🤭
Can a ring of IR Leds from a security camera be used to trigger an opticomm, or do they need to be way more powerful?
@@peterfairlie2296 Awesome. I'm guessing you used a 12v battery array because 5v gpio wouldn't cut it?
@@peterfairlie2296 One last question, how many amps is your 12v battery pack? NiMH? Need to go battery to 3pin molex picoblade on mine.
@@peterfairlie2296 Nice! i just need some molex picoblade connectors and I'm set. Just got my optocouplers today.
Mr. Wizard.
Hahahaaaaa very creative my friend
How do you program the opticom with the traffic signal? Lol do you need like a complex traffic signal controller? Because I have a traffic signal and I would like an opticom some day
He has it flashing at 14hrz
@@floridaman7 I’m not talking about that, I’m talking about how does he have the opticom wired with the traffic signal
Is the flash light using standard LEDs?
@@peterfairlie2296 It's a white light in composite, but if you measured the full spectrum I bet it outputs at least a little bit above the 780nm mark on the red end.
What did you wired the opticom and signal to?
Question: does this skip the sequence and just immediately make the light green, or does you country's traffic light controllers just not do the "red and amber together" signal to prepare drivers for the green signal?
correct, we dont do that
can you show the flipper part? it looks like a good ir blaster that could be used to extend the range of the flipper? i would love to see how you've hooked things up, i ususally find 12V ir rings like that and cant figure out how to build one myself

Instead of modding a flashlight for those that fear mechanical tampering stuff, one could probably just take a raspberry pi and have a led flashing with a small python program?
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
GPIO.setwarnings(False)
GPIO.setup(18, GPIO.OUT)
frequency = 14 # in Hz
time_period = 1 / frequency
while True:
GPIO.output(18, GPIO.HIGH)
time.sleep(time_period / 2)
GPIO.output(18, GPIO.LOW)
time.sleep(time_period / 2)
Yup. Similar for arduino boards, but in C, and possibly with less code if you use one of the lightweight PWM libraries.
Do you have a video with the discriminator and control cabinet? Something like this I could use as a gate controller to my driveway. It would be totally legal for me to have it in my car at that point, maybe tune it for a different frequency or set it as a decoder.
So you built the battery power for the opticom . And the opticom is from an old security camera or can that piece alone be purchased . I’ve never attempted such a project
But the battery, that looks like a Mcgyver project, you have a video on the power source specifically?
Hi I have the exact flashlight same model everything can you send me instruction on how to do exactly what you did please and thank you
i can use this cus when im rideing a motorcycle or scooter some on some sort of sensor in the ground that dont pick up that shit so im at the light for 30min befor i just run the red cus its late no cops around and no cars on the road really
Yo I do same shit,,hate that .but I have a led ring around my headlight so I want to rig it to the 14 MHz,and see if it works,,,
I have a flipper where do I get what you used in the video?
Have you made it
man very..that thing is powerful for sure haha 14hz FTW
which firmware do you use
At that time Xtreme
based
Question: Is this legal to use irl?
I don’t think so
Where did you get the led for the flipper gpio?
ua-cam.com/video/TrVLmTLHgew/v-deo.html
ah! I have the same stobe light!
Do you have any system diagram or schematics, def would love to try this?
iM not proud of it but is true, im obsessed! I would LOVE to pick your brain! it is so amazing what you can learn for free online if you seek it out. How can I find the information I need on programming a flashlight?
So how bout u show how u set the flashlight to 14 MHz and at 50% ,,or how to set it up wit flip zero..
You should try flashing a laser diode at 14Hz for super long range
I'm actually working on such a device right now! I'm building a 5mw red laser that will be a GPIO accessory for the Flipper and will be modulated by the Flipper's PWM. Using 14Hz the beam could be directed right at the Opticom traffic sensor from a long distance away.
@@peterfairlie2296 I just discovered your channel, as a guy that doesnt know anything about this im really impressed. I would really Love to know How you do all of these things cause i would like to do it too. planning in buying a Flipper, but i dont want to just turn off Tvs 😅.
Also want to know what else the Flipper can do and How to make it possible. I’ll suscribe to keep updated on your vids!
What is the minimal amount of ir needed to trigger one of these?
14hz
Have you encountered opticom preemption that is filtered by the optional code ID sequence?
@@peterfairlie2296 i have been binge watching your videos. You’re brilliant!
Subscribed and will be eagerly awaiting more
@@peterfairlie2296 this info is amazing, I was looking everywhere to try and find some kind of protocol which interleaves vehicle class and id info but couldn't find it anywhere and your explanation makes sense. Where did you get this info of it not being implemented as a security lock? Is it just from you messing around with it or do you have some top secret inside sources?
I have read on certain documents from the manufacturer that Opticom systems can be programmed to not trigger without the programmed id's in the base 10 or 14hz signal. I assume that certain cities probably just have a few class and id numbers stored just to prevent such easy triggering of the system.
Update: a lot of cities in Florida have the Opticom sensors and I have programmed an mcu to pulse a 14hz signal. It doesn't work and I know that its not on my part because I tested my device extensively. Either the sensors are out of commission, or they have the ID code trigger enabled which I believe is the case. Out of all the videos I've seen on UA-cam, most of the ones that I've seen work are in northern states such as Pennsylvania. I don't know if this is necessarily true but when I visit new York soon I will test it in surrounding ares.
Where did you get traffic light from?
I bought it off a guy that services the traffic lights for the city.
Except most of the newer ones have encoded pulses so people can’t do this. And they have certain encoded sequences that apply to certain cars people depts. And so many intersections are monitored with cameras these days. Most. And a lot of intersections have white lights that come on above the signal to indicate a trigger. Which turns off the second you clear. So it’s pretty obvious that you weren’t a emergency vehicle. And they carry big fines for using it. And cities have traffic lights that are all centrally controlled and can instantly see a trigger and get eyes on who triggered.
What gauge wire is the white one is
@@peterfairlie2296 on the ir illustrator
Lol, I've never seen that on a traffic signal, and they don't work that way round here!
Hi Peter,
Can I email you a question?
Did you change the firmware on the flashlight?
He swapped out one of the surface mount resistors. The rest has been left as an exercise for the reader. Your mileage may vary.
What type of career requires learning these types of things to fully understand what he’s talking about?
Electrical Engineering
Are you from canada? I feel like I can hear an accent
How did you mod your flashlight ? :O
I imagine the timing of the chip is set by a resistor value or a voltage level. Either way, one or two resistors of a specific value in the circuit would change it.
That, or he just built a completely new mainboard for the torch to replace the original one
@@dafoex You were right the first time. Change a resistor.
@@lucasthompson1650Yo my tactical flashlight has 4 resistors but each of them are rated at 1 ohm. It has 4 different modes so I KNOW they are related. Can you give me a hint in the right direction?
@@blakexe it must have more than just 4 resistors on the board -- "have you looked on both sides?" is what my old EEng teacher would ask.
I'm just gonna take an 'edumacated' guess that it has at least 1 OpAmp (very tiny black chip, 3 pins) and either an integrated driver chip or some sort of timer IC ( tiny black chip, with 4 or 6 or 8 pins ) plus a capacitor or two -- at least 1 between the battery +IN and the rest of the board.
This is what most cheap and cheap-ish tactical flashlights have inside these days, and while they might be able to be adjusted to work like this, they can't be modded as easily, or the same way, as the one Peter used in this video.
I suggest looking at dirt-cheap PWM LED driver boards... for $3 or so you can get a board that will let you control the duty cycle and PWM frequency (typically up to ~150kHz) of any 5 to 12VDC device you plug into it. You can find them on Ali express, amazon, digikey, mouser, etc. If you can extend your budget up to $8 or $10 you should be able to find a PWM driver board that you can easily control from an Arduino or Raspberry Pi using Python or C or whatever the hell the kids are using these days... Rust? :p
With programmatic or API control, the number of traffic light hacking, vehicle engine timing, seizure inducing patterns you can execute will be limitless.
😜
Can sell me a modified flashlight?
Bah. Bullshit. The headlights work. It doesn’t have to be exact its about being close enough to confuse the sensor.
hate to let you down but headlights don't work has to be IR
Did you factor in the fact that just because it changes one light to green, maybe it doesnt change the other green light to red??? that would cause a bad car accident... lol then i guess you could just slowly mosey on past the intersection without drawing attention..... (sorry for the dark humor lololol)
Opticom doesn't work that way, it does a fast yellow and red the opposite direction before turning it green.
how did bro get a traffic light 💀
