I have 2 AAISP FB2700 firewall devices here: The unit in service, and a backup.

The thermal management in these is poor, and they run too hot.
The cheap internal 5v PSU is usually the first thing to die.
They issued a 'modification' some time back, which was the same PSU with the switching transistor extended out of a hole in the plastic casing with a half-hearted heatsink on it.
Yes, really.

After multiple PSU failures, I've given up on the internal PSU and fettled them to use an external 5v PSU thusly:

The running temperature is now much lower in the case, and PSU-swapping is trivial.

In mind of the Soldering Iron threads, some may notice the use of my elderly Weller PU-2D iron here. This is on account of my normal kit being out on loan to my Brother Dear, and not yet returned!

Made my scanner work.  Or not, as it appears to have some inbuilt SCIENCE that stops it from scanning banknotes.

They do, a friend worked on some of that tech.

Yes. Banknotes have something called the EURion constellation* – the scanner spots this super-secret stenography hidden on banknotes and gently spanks you for your tentative turpitudinous temerity.

*they have some other stuff they don't advertise, so even you do manage to copy, the results are missing some secret sauce they can detect.

ITYM steganography.  It's like stenography, but with thagomizers.

I promised a picture of a five-dollar bill to anyone who could provide me with some chap's surname for entirely innocent purposes.  My grate frend Al replied within two minutes so I wanted to send him a picture of a crumpled twenty from my wallet instead, but had to make do with a stock photo snarfed from Wikinaccurate chiz.

I don't think the technology is built into cameras, my iPhone had no problem taking a picture of a £20 note just now (although it's not going to have quite the same resolution as a scanner).

No, your reply wasn't blatant name-calling but it was at that level and completely irrelevant to the question that was asked.

> ... you are happy creating a fictitious Yahoo account...
It was created so long ago that there was no requirement to confirm that details entered were genuine.  It's the only reason I maintain the account.

Irrelevant? without going in to the detail (which it sounded as if you didn't want to hear) I invited you to examine what appeared to be your bias against Google as compared to Yahoo. As for "fictitious" details, you don't even need a google email address to open a Google account (and, through that access Google Photos unlimited image storage at 16Mp or below).

There's no need at all for you to have a reason not to use Google if you don't want to, but I seem to have upset you by pointing out the apparent inconsistency, for which I apologise.

Not so much today as over the last week.

Installed one new Win 10 machine to hold our database.  Went smoothly.

Installed my new Win10 machine.  all but one other computer could see the new machine.  The only one that couldn't was the only important one!

installed Dragon 15.3
installed Office 365
both went smoothly but cannot get any of my custom commands to work!!!!  Apparently the Microsoft Word 16.0 Object Library is not being shared with Dragon!!!!

I therefore face doing a complete Office removal and re-install to try and solve the problem and hope that works.  Working that out has taken about 18 hours of effort for zero benefit!

Another company told me I needed to pay £500 to upgrade their software to use Win10.  Took a chance and it works perfectly!!

I had made the crazy suggestion at the cycle forum meeting that we build an active map for our stall at the Cycling Scotland conference in our home city. A big board which when you touch key points would play a video of that location.

Raspberry Pi Zero based with a plethora of MPR121 capacitance sensors (google banana piano for an idea).

Rolled it all up and here it is - seemed to work very well and only needed rebooting a few times. That was worrying as I was not in attendance after switching it on the first time.

That's probably more effort than anyone at the council's put into molishing cycle infrastructure.

Optimizing my wifi by moving the other box upstairs (which I've been meaning to do since forever). Carefully positioning means it now manages to give an acceptable signal in the remote command centre and – finally – decent wifi coverage upstairs, including my wife's office so she can't keep complaining. And I can listen to the Sonos thing in the bath. Hopefully. This is what happens when you buy a house made out of bricks and asbestos and proper stuff, rather than timber and plasterboard.

The foil backed plasterboard isn't great either :/
