HD-SDI on old RG-59 cable?! How…. No, why, was this done and why does it actually work?
Some day this will hatch into a beautiful butterfly.
I don’t know how this was wired. I legitimately can’t figure it out. Long handled BNC extraction tools aside, I can’t understand how anyone was actually able to see the back of the router to make the connections.
Seriously, I’m having a great time here, even if my brain does occasionally rattle a bit…

I’ve used these for years whenever I find them on the surplus market. These are really good surge protectors. They often have a label saying not to remove them — they are usually deployed on installation of fancy leased office copy/scan/print/fax machines costing kilobucks and are required as part of the service agreement.
The green LED on this one is just a power on light. Note that some units have a safety relay inside and will not power on unless a good ground is present. They’re idiot proof. You’ll see momentarily why the ground is very important.
All of them can be opened without damage. On this one you pry from the back and carefully release locking tabs.
That… Uhh… That’s a static sensitive warning. I’m guessing that was some engineer’s joke as there are no static sensitive parts in this unit at all.
Here’s the good part. Surge protection on the inlet – line and neutral first meet these MOVs and gas tubes. Now this unit is kinda interesting in that it’s wired like this:
Line in —-{two MOVs in parallel}—[gas tube]—ground—[gas tube]—neutral
Normally I see the gas tubes and MOVs in parallel.
Not gonna question it; it works.
Now those are just the castle gates. There are more defenses beyond…
L network filters in line and neutral. Each must flow through an inductor on its way to the equipment. Once it passes the inductor which will resist the passage of both high frequency gibberish and spikes with fast rise times, a capacitor damps out the high frequency components. If you’re curious as to how this works, go deeper down the rabbit hole and research basic filter design. It starts to get quite fascinating.
One cap goes from line to neutral, two go between L/G and N/G. One resistor up before the inductors will bleed residual charge off these upon unplugging for safety.
This is a feature not present in most AC powered smoke alarms. Don’t touch their pins after disconnecting them. They bite.
Additional MOVs are provided here and are behind 2 amp pico fuses. Not sure why the fuses are used, but for a surge to hit these, it would have had to get through the primary defenses.
Telco protection stage; this uses poly switch fuses for current limiting (self resetting) and MOVs to limit voltage.
The MOVs can even be replaced if they pop.
Cool, right? I’ve never had any gear get damaged plugged into one of these. They Just Work.

How to market a damaged destination.
Yeah, uh, looks like what you see in the bowl that tells you that you ain’t going much of anywhere for the rest of the day other than to grab a dose or two of Immodium.
I was up in Stuart this weekend and drove a bit north, then looked at the riverfront on the Indian River… it started raining heavily before I could get any pictures, but the water was dark brown and REEKED. I’ve seen sewage lift station pits that smelled better than this. (Actually… for the most part, unless there’s been no flow for a long period of time, they smell like the scented detergents and soaps that go down them; the brown trout are submerged and aren’t really able to stink things up.)
Now I have something to liken SFWMD to: a lift station in a giant river of shit.
Fairly nasty pit. If those chunks of brownish soap/oil residue break off or build up on the float switches, they can cause drama. Source: Fletcher Property Management.
For all the amazing things about the Walt Disney World parks—- egads, their website is a mess.
I dunno, it gets the job done, but there are a lot of dead links and things that just don’t exactly convey Disney Magic. 😉
Being that this is nothing more than a mere shitpost, here, have some memes
YAFULC = Yet Another Fucking Urban Lifestyle Center.
Oh, yaaawn… A while back I’d seen plans for the development to go where the old Dania Beach Hurricane roller coaster and Boomer’s park (used to be Grand Prix Race-O-Rama) were. At the time the plan appeared to basically be to build YAFULC-In-A-Box with the parking outside the project.
Now that demolition began on the old wooden coaster, I just looked at the more recent plans. The project is now known as Dania Pointe (the extra E is for “Bullshite“!). It’s YAFULC.
Access to the site is *AMAZINGLY* limited and yet the plans call for 750 residential units — this means that either one (or a combination thereof) are true:
A) there are no plans to actually build the residential units;
B) the residential units are designed to never actually be occupied and are just to be used as token flippable properties to be sold to overseas investors.
If the residential units ARE actually built, all access to the site will be permanently cockplugged, so forget that.
Here’s the pretty picture showing the glorified parking lot from Kimco. Yawn.
Well there you have it…… South Florida, where we truly pave paradise and put up a parking lot.
Wanna bet Stirling Road will very suddenly grow a set of express toll underpasses?

Just sit back, relax, and light off a bad CPU fan.
This CPU fan is off a $LOLWTF robotic broadcast camera control system. “Enter Bearing”? Sleeve bearing. They cheaped out on the fan!! Why?! When you pay THAT MUCH for a product, is it wrong to expect it to be built to last?
Well then. This is more enjoyable than a badly done demonstration of how to give yourself waves by braiding your hair and baking it to death with a flat iron.
*prepares to post politically motivated spiel about how this state are a bunch of idiots, based on voting results*
*remembers that this is Florida, so calling it a bunch of idiots would be totally pointless and redundant*
*shitposts instead*
How does Google Earth form these “ground level” images? My guess is it’s via compositing aerial photographs taken at different angles and attempting to basically detect object boundaries then apply the images to them as textures.
It works okay for some things like buildings standing out in the open, not obscured by trees.
For other things, umm…. Well, I particularly like the floaty treeblobs. They give you all the shade of a normal tree, but without any of that pesky risk of bumping into the trunk.
I keep feeling like they should integrate some really stupid auto racing game into this view with amusingly retro controls (like Pole Position)…!
