How do you even let this get past QC?

Ordered a replacement screen and frame for my broken Galaxy S4.

What came just… failed

Original frame at right,  motherboard next to it.  Note the puzzle piece shape that accommodates those SMT parts.

Old at right,  new at left.  Note no indent for those smt parts.

Foiled by Chinashit. Can’t blame me for trying can you?

Oh it’s one of those new age free energy amplifiers

This is from the schematic to a Tytera MD-380 radio.

Shown here is the mic preamp. I was curious to see what this looked like as transit audio quality and level are said to vary a lot from one radio to the next.

Unless I’m missing something – there’s no way for DC voltage to get in there and let those transistors do their job.

Annotated to show where capacitors block DC:

Looks like Miami traffic at rush hour--- it ain't getting in or out.

I’m considering buying one to play with but. .. uh… only somewhere with a good return/exchange policy.

Party like it’s 1999

The yellow encased object is a video field delay line. It’s a fixed delay (mechanical / acoustic) that allows one field of an interlaced NTSC* picture to be overlaid on the other in case of a tape dropout. They’re normally found inside VCRs. Why do these monitors have them?

This set of ancient monitors eventually got too tired to really work and may be up to 17 years old. Not a bad run really.

The Watchman

When I first started working here, I noticed this beautiful but shy little man hanging out with our night watchman.

image

He would only get close to a couple of people, anyone else would spook him into running off.

One day, he stood on that little wall and gave me a squeaky little meow to come over, and now every day ends with this:

image
Nope, you can't leave, I'm in your hand

I think every broadcast facility should have its own fuzzy creature watching over things.

It's all good, we've got Sargeant Beantoes on watch

There’s another cat around here from time to time but he’s evil so let’s never speak of him again. He’s out there. Watching. Waiting for another victim to lure for a clawing… But he won’t get anywhere near this sunny orange sweetheart.

Casa del carajo

So we meet again

Despite the booming business by scrap rats, decrepit abandoned lines still aren't removed

For a good time call

Two enemies of your electronics: water...

That'll do

Poor bunnified exciter

So unloved

Sprint cleaned up their former nightmare

Hey at least I get paid for holidays and overtime at this job

Thank you for using American Tower Corporation. Have a nice day. Sorry about the waterlogged shoes.

How to use your racks and avoid unspeakable engineering horror

On most equipment racks you will find the following pattern of holes:

** * ** * ** * ** * **

No, it was not drilled by a drunken woodpecker.

image
But this gear was installed by a drunken bonobo at 4 am.

See the holes with the wider spaces between them? Good… IGNORE THEM! They do not exist! You never saw them. Fnord.

See the closely spaced holes? Imagine they’re the dots on a double 1 domino. This means there’s a center line between them. See attached photograph. The center line will be the edge of each piece of equipment to be mounted.

Why are the center holes there? Okay… Fine, I’ll admit to their existence. Begrudgingly…

Some oddball accessories like cover blanks and cable lacing bars may be screwed in here. In the case of cover blanks it’s usually on weird ones that have a single hole in each end of a 1U* high blank. If you install a lacing bar this way it will be in the middle of one rack unit space – handy for the rear rails behind a patch panel.

Otherwise, do not use them unless you really have good reason to.

If you do mess this up…. Well, look at the wonderful mess in the photograph. Huuurrrrrgghhhhhhhhhbbllll.
