- Using any Cell Phone with the Strobily app, and an easy to built optically coupled sensor device, the exact OptiCom signal of 14.035 Hz at a Frame Rate of 2.5 seconds can be achieved. This optically coupled sensor device will allow you to interface directly with your Cell Phone and relay the captured signal to a high power Infrared LED array. Traffic Signal Preemption typically uses OptiCom 10 & 14.035 Hz @ 2.5 fps strobe rates. • Flipper Zero Controlli... Also see Part 1 of Traffic Light Preemption using Flipper Zero

Crazy I remember when people used to get tickets if they got caught flashing their High beams at the lights I did it a few times out of curiosity. But I stopped because I didn't want the tickets the town was giving out if caught.
Oh man that's cool
That’s cool just set your headlights to the frequency of the opticon thing
I'll take "Things that never happened" for $2000. High beams can not and have never been able to interfere with Opticom, therefore there is no reason whatsoever for it to be illegal. 🙄
Thank you this is so so interesting and epic!
Peter Fairlie. Look at the Walking Signs See if they blink when the Poles read that signal They should stay blinking till no signal read by poles
@@peterfairlie2296 I had the Mirt Years ago
Dude this is a crazy video! Also, 6" (double quotes) is 6 inches. 6' (single quote) is 6 feet.
@@peterfairlie2296 I can't wait! I shared your video with a few people and subscribed. I'm impressed man! Keep it up!
Is the delay necessary and would it still work without the delay?
14:16 need to be careful Mercedes is confused
careful some intesections have cameras
is it possible to change to red or is there no frequency that makes it possible
Do you need a UV light? Couldn't I just use the flashlight? and if not could you show where I can buy the items for this and maybe show us how to build it? thx
He showed how it's made in the "Flipper Zero controlling traffic lights?" video and yes you could use a (modified) flashlight but that would be very obvious to people around you and you would get the cops called on you pretty quick
12 minutes into the strobing lights "oh yeah if you epilepsy you should prolly not watch this"
A LITTLE LATE BUD
You got a print/schematic/design for the battery pack?
It would appear to be 8 AA batteries connected in series, pretty simple, if you need schematics for that you shouldn't be messing with stuff like this, but here's a text description. B(attery)1 donates your "main" POSITIVE connection, B1 NEGATIVE connects to B2 POSITIVE, B2 NEGATIVE connects to B3 POSITIVE, B3 NEGATIVE connects to B4 POSITIVE, B4 NEGATIVE connects to B5 POSITIVE, B5 NEGATIVE connects to B6 POSITIVE, B6 NEGATIVE connects to B7 POSITIVE, and finally B7 NEGATIVE connects to B8 POSITIVE, and B8 donates your "main" NEGATIVE connection, where you should see 12v (an AA battery == 1.5v and 1.5 X 8 == 12) Remember B1+ and B8- are where you take your power from once done assembling
FWIW you could use 3 18650 batteries (4.2v each * 3 == 12.6v) for a slightly smaller and lighter footprint with WAY higher amperage potential and much higher mah rating, and I think 18650's charge faster than (rechargeable) AA's too.
@@colind6797 18650 @ 4.2vdc??? I think you're confused. The 18650 is 3.7. The 21700 (which are hard to get thanks to Musk) go up the 4.2.
@@MegaDarksyd My 18650s have always come off my chargers @ 4.2v since I started vaping 7 years ago, back then we had to wind our own coils and thread a cotton wick thru the coil and in the case of tanks there was usually a special way you had to faff with the tails of your wick to allow the tank contents to wick fast enough to prevent the coil from burning the wick but at the same time not letting it all leak out when not in use, and in the interim the same goes for for everything else I've encountered that runs on 18650s
what the schematic of the circut?
He shows how it's made in the "Flipper Zero controlling traffic lights?" video
Watch dogs irl
Can you link somewhere to the timing diagrams?
@@peterfairlie2296 well it seems like you worked out the timing for the app, which is easily grabbed via screen shot. I am just wondering how you derived the precise on off times, especially how you vary the duty cycle on the 2.5 hz bursts in between the 14.035 hz bursts. They are not all the same. I figured you found an opticom pulse timing/coding specification sheet somewhere.
@@peterfairlie2296 yes I understand, I am just curious if there is any open specification of the opticom protocol.
@@peterfairlie2296 the opticoms in my area have vehicle class codes, will not respond to unencoded opticom signals. I might try and capture some in the wild
@@peterfairlie2296 yeah I figured as much. You’re super clever. I’m going to put up a datalogger that records IR signals next to an opticom sensor in my neighborhood. Have it dump the buffer when it sees the 14hz signal. The class codes might be encoded in the timing of that 2.5 hz signal you programmed. The opticoms here in my city have a light that comes on to acknowledge the emitter. I guess so crews can anticipate the light changing. Does your city have that feature too?
@@peterfairlie2296 what do you think of uspto 7333028? Looks like it uses a combination of amplitude and frequency modulation superimposed on the priority pulses (10/12/14 hz)
Hmmm.. 🤔 can we do this with ESP32 I wonder..
Was thinking the same ,got the flipper zero wifi dev haven't try that yet ,
How does he keep getting into my gated community the guard is not supposed to let him in. And he always shows up when the guards are gone I have nobody to call and complain to.
Why do you have six entries for the pattern loop When you can just have two?
It's easier for me to get prebuilt optocoupler boards with a relay all in one, will the relay be fast enough for this or no?
A mechanical relay would be to slow. Use the optocoupler I used in this video: th-cam.com/video/TrVLmTLHgew/w-d-xo.htmlsi=fmtqPuZzchabc_Ji&t=474
@@peterfairlie2296 The pc817 optocouplers are a better specced newer version of the 4nXX line apparently, they should work just the same then eh?
They’re much more prevalent on Amazon if you want them on a board already, I can’t find ANY 4nXX optocouplers on a board already
The PC817 is not using a Darlington transistor pair and won't produce the needed current. Use what I specify only: www.amazon.com/s?k=4n33
