Love how the Raspberry Pi is a on going joke on this channel. XD

I dunno why these videos have me facinated... Traffic lights have always facinated me and my engineering brain on how high tech they've gotten... I love my city, up where I live is all new area in Peoria, AZ out in the far north desert and all the traffic lights they are building out are the camera/radar systems and they adjust for rush hour traffic and as I drive up to the intersection at night when traffic is low, as I drive up to the light, the lights already registered me and changed the traffic light to green for me by the time I get to the intersection... and if a light turns red for other traffic, its only red for as long as it needs, it swaps back right away making red lights short... where in Phoenix where still today they use ONLY old school detection lines in each lane and all traffic lights are on timers and extend / change only if someone pushing the walk or is sitting there... makes late night traffic suck, because you sit there for like 5 minutes until the walk signal for oposite starts blinking and then gives you a greeen light... Phoenix is testing some smart lights out on a few intersections, but Peoria is using only smart lights and they just set up the main throughway (Lake Pleasent Pkwy) all lights to go in sync during rush hour, meaning if you catch one green light, you will get all other green lights all the way up to keep traffic moving in waves. It is truely amazing and gives the roadway a MUCH higher capacity too! Thank you for showing how all this works!

Add some dielectric greace to the connectors - helps with this type of failure.

do your self a favor i do a lot of outdoor cctv camera installes fill the jack with dielectric grease it will help keep water out of the connection provent high moister air from corroding the connectors. started doing this about 5 years ago on my installes have almost stoped all service calls.

I know you were joking in this case, but Raspberry Pi's can show up in some interesting places. It's been hard for hobbyists to get their hands on them because commercial customers keep getting priority.

Rubber tape is good for water tight seal. The black stretchy tape used on service connections.

Thank GOD this Equipment can be sent off and Repaired. 👍🙏

Would love to see how the cameras do their detection on the laptop while there is some decent traffic at a biger intersection. That was cool to see.

they should redesign that connecter on that camera

As for the connector, dip it in NO-OXID grease, it's made for this, it will seal from moisture and prevent corrosion.

You got me on the Raspberry Pi, I was like is it really, no way... that can't be right. lol

Do the traffic cabinets you build and maintain there require much for surge protection (incoming AC, surveillance cameras, etc.)? We do a lot of work in projects down in Florida but was curious to know if that's needed in your neck of the woods.

Cool stuff!

Why am I so interested in your videos. I can't stop watching them.

Do the traffic cabinets have any kind of emergency power backup should the electrical power go out and the traffic signals would remain operational during a power outage?

So are the cameras AHD video and the box behind it is some sort of converter-network adapter? Otherwise why would the image be rolling like an analog signal that's not synchronized?

That is an "Engine board" in there with 2 Ethernet ports, SPI, I2C, 8 Serial ports, 1 USB2 port of which 4 are synchronous up to 1Mbps. Typically a 266 to 466 MHz processor running a older version of Linux kernel. Typically they use CPUs that still has support for HDLC/SDLC. The life expectancy of such a controller is 20 - 30 years. I think a bit longer than you would get an RPI, expecially under these conditions. Dont worry about the dust, dirts, ants and rats, its the truck vibrations that kill electronics next to the road most of the time. There is no chance that an RPI will be as reliable, because its not designed to be. Its goal is to be an educational toy. Now you can build some production stuff out of lego, but its certainly not going to be reliable, consistent and so on if produced in volume. So its all very very old technology, but reasonably reliable. Thew only thing that kills me here is that STAR network of SDLC. It is running at a slow 153200bps, but still it is NOT designed to be a star topology, and you get some serious reflections in those lines, because only the MMU and controller are terminated. So the BIU, CCUx2 are not terminated, yet on the ends of a star topology. The SDLC standard is not supposed to be able to support so many terminated nodes. It is just crazy that nobody knows, nobody cars or notices this in traffic cabinets? Apparently it is working fine. Its like putting vegitable oil in your car and say it runs fine. Its not designed to run with that kind of oil, and maybe it runs, but it will be much more reliable if you do it properly.

Mother nature can take out anything.

Don't you use Dielectric Grease to keep the water out of the Cat5 cables?🤔

Raspberry Pi ;-)

I would assume that the processing power would be roughly comparable to a raspberry pi

How would water get up into that connector? There’s not a leak on the top of that enclosure is there?

I was like no way, a Raspberry Pi really? haha

Lightning strikes are such a bother

Do I hear a lightning storm in the back?

What do the signals show when the system is starting up after flashing is turned off?

You would think they would make the graphical interface a little more modern.
