Cell Phones Controlling Traffic Lights 

@@peterfairlie2296 I had the Mirt Years ago

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. 🙄

What in the tyranny....

@@peterfairlie2296 I can't wait! I shared your video with a few people and subscribed. I'm impressed man! Keep it up!

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

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

No

Was thinking the same ,got the flipper zero wifi dev haven't try that yet ,

@@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)

Strobily

For the hell of it, I'm sure lol

A mechanical relay would be to slow. Use the optocoupler I used in this video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TrVLmTLHgew.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
