Metrojet crash Eygpt
A0283
seems the area of interest of the bomb going off was a hole found under the keel near the tail
a bomb/IED of 1kg TNT so the RT news says
that maybe explains seeing no cargo hold area or cargo doors or floor back from the wing box
assume bulk loading of the bags and no ULD's used on this airline?
remember this A321 had a planned 12 layover at SSH unattended for the most part

Barometric Trigger
Very very easy. Just think of two wires that are pressed together by an expanding balloon. It would take an average school kid about 30 minutes of labour to design accurately.

"How difficult is a barometric-pressure device as trigger?"
'Safest' would be a barometric-pressure trigger that starts a timer. Pressure altitude was reached earlier in the flight if device was placed in cargo-hold.

Changes to come??

A0283 -two unexpected ones ( bomb hiding places)
Control eng - waste tank not easily accessible compartment
if by tail section they mean APU or HS (or one of the two suggests above) it really does question airport security if someone opened a "maintenance panel" to place a bomb.
Of course my original post concerned doors/hatches only if the industry now has o consider securing maintenance panels/hatches what a nightmare.

The modern mobile phone has a barometer, GPS, accelerometers, microphones, timer, radio links, a huge amount of computing power, and a massive support ecosystem of development tools and optional hardware. It's also an everyday item and possession is entirely unremarkable. You can develop the software anywhere in the world and deploy it anywhere else on demand.
You couldn't hope for a better platform to design an efficient and flexible bomb trigger mechanism, all for a couple of hundred dollars and accessible to people with hobbyist-level skills.
That engineering problem has been solved.
I don't know, of course, whether this is what was used; a cheap wristwatch is still a sensible alternative. But this is what I suspect.

I agree that It is a possibility, but from an pure engineering standpoint of view, my humble opinion is that using a smartphone as a detonation trigger seems to be too complicated and potentially unreliable way, while, obviously, there are much simpler ways to achieve the same effect, like the $1 wristwatch that you have mentioned.

It appears all suggestions of "HS jackscrew failure" branch of PPRuNe armchair investigation was wrong

Russia seems to be serious re Bomb
For a second straight day French warplanes hit a command post and a recruitment center for jihadists in an Islamic State stronghold, Raqqa, the French Ministry of Defense announced on its website, while Russian news reports said a Russian submarine had fired cruise missiles at Islamic State targets in the same area.
Russia struck Raqqa with advanced Kalibr cruise missiles launched from a submarine in the eastern Mediterranean, the RBC news agency reported, citing sources in the Russian Defense Ministry. The agency said it was the first time Russia had fired cruise missiles from a submarine during a war.

screw jack failure
Think the poster meant mechanical failure, would have thought a bomb in apu compartment would have severely disprupted HS and ripped jackscrew to pieces.

How do you protect your 'mole', if the device is set to trigger while the a/c is still over home territory, leaving evidence right at his doorstep? Doesn't make much sense.

I defer to demolition experts on whether it is doable.

LifeNews published cut from old video with suspected luggage piece.
LifeNews LIFE | NEWS
"In contrary with other luggage, this one seems bears burn marks from inside".
UPD: Nevertheless, I still not think it was luggage bomb. My opinion it was planted outside rear pressure bulkhead and it was planted from outside.

There's nothing to worry about with what has been posted here
This is stuff that an industrious middle school kid with a bit of a mechanical aptitude could easily come up with.

If some people here, not being explosive experts, can imagine such mechanisms, don't you think Daesh have been able too ? They aren't probably (and unfortunately) completely stupid.

There is no evidence of the RPB being thrust forwards!
