So the middle station refilled 3025 = 10460 – 7435 bottles, roughly eight bottles a day, every day, for a year. Seems like a lot of refilling, doesn’t it?
Unfortunately, I didn’t take pictures of the other watering hole last year, but here’s what it looks like now:
Overview:
Gym water bottle refill station A – overview
Left:
Gym water bottle refill station A – left
Center:
Gym water bottle refill station A – center
Right:
Now, it’s entirely possible I have the two stations reversed, in which case I have numbers for all three displays:
Left = 242 = 4758 – 4516
Center = 633 = 8068 – 7435
Right = 800 = 9689 – 8889
Does a bottle or two a day, every day, for a year, seem more reasonable? Hard to say, so, with a bit of luck, we’ll have more data next year.
There’s a good reason this was the last pneumatic tee fitting on the rack:
Malformed pneumatic fitting
The center fitting should be a male 1/4 inch NPT connection, but it’s completely un-machined. Alas, I no longer have a 1/4 NPT die in my tool chest, so it’s not an easy fix.
The two female connections are fine, so it must have been one of those rare QC escapes.
Lowe’s marked it down to $0.47 on clearance and I still couldn’t justify buying the thing.
The ANENG AN8008 / AN8009 multimeters have 3.6×10 mm ceramic fuses on their inputs:

Based on past experience, at some point over the next year or five, I’ll forget to plug the hot probe back in the voltage hole before measuring a power supply:
AN8008 multimeter jacks
Whereupon the fuse will blow.
So, for about five bucks, a bag of 10 A and 0.5 A axial lead fast-blow glass fuses just arrived from halfway around the planet:
3.6×10 mm axial fuses
They have the right body size and, in this application, fine points concerning current ratings and cartridge composition don’t make much difference. If I actually need one, I’ll snip off the leads, jam it in the holder, and move on.
The spam filters on my email account snagged a message with an impressive subject:
Be sure to read this message! Your personal data is threatened!
The sender used my very own email address, sending the message from a server with a Mumbai IP address:
Hello! As you may have noticed, I sent you an email from your account. This means that I have full access to your device. I’ve been watching you for a few months now. The fact is that you were infected with malware through an adult site that you visited. If you are not familiar with this, I will explain. Trojan Virus gives me full access and control over a computer or other device. This means that I can see everything on your screen, turn on the camera and microphone, but you do not know about it. I also have access to all your contacts and all your correspondence. Why your antivirus did not detect malware? Answer: My malware uses the driver, I update its signatures every 4 hours so that your antivirus is silent. I made a video showing how you satisfy yourself in the left half of the screen, and in the right half you see the video that you watched. With one click of the mouse, I can send this video to all your emails and contacts on social networks. I can also post access to all your e-mail correspondence and messengers that you use. If you want to prevent this, transfer the amount of $796 to my bitcoin address (if you do not know how to do this, write to Google: “Buy Bitcoin”). My bitcoin address (BTC Wallet) is: 14tfS3 << redacted >> WH6Y After receiving the payment, I will delete the video and you will never hear me again. I give you 50 hours (more than 2 days) to pay. I have a notice reading this letter, and the timer will work when you see this letter. Filing a complaint somewhere does not make sense because this email cannot be tracked like my bitcoin address. I do not make any mistakes. If I find that you have shared this message with someone else, the video will be immediately distributed. Best regards!
The threat uses Nigerian-scam grade English, evidently targeted at folks with both a guilty conscience and a tenuous grasp on how email works. I thought those same folks would have enormous difficulty converting dollars into Bitcoin.
However, feeding the wallet ID into a Block Explorer shows three transactions over the last two days, with the account now standing at 0.43069539 BTC = US$2269.44. I have no way of knowing how many emails went out, but obviously three people had sufficiently guilty consciences to (figure out how to) make a Bitcoin transaction.
Update: The ransom payments tapered off after five days.
Bitcoin Scam – Total
I don’t know how many different scams came from the same source, but $6700 (at today’s market rate) says this campaign paid better than most legal occupations outside the fintech sector.
Somewhat to my surprise, Aneng AN8008/AN8009 multimeter PCBS sport what looks like a reasonably accurate current sense resistor on the 10 A input:
AN8009 10 A current shunt – top view
The legend says 0.01R and the conductor doesn’t look quite like pure copper:
AN8009 10 A current shunt – side view
The indentations look like clamp marks from the bending jig, rather than “calibration” notches made while squeezing the wire with diagonal cutters and watching the resistance on another meter.
One might quibble about the overall soldering quality, but one would also be splitting hairs. I doubt the meter leads could withstand 10 A for more than a few seconds, anyhow.
If you buy enough of something, you can buy pretty nearly anything you want, even cheap precision resistors!
I know no more than you do about the situation, but I’d lay long, long odds Hannaford created the poster with a more recent version of Microsoft Word (or whatever) than the recipient organization has available, making the file essentially read-only.
Not casting shade on ’em; sometimes, you do what you gotta do.
FWIW, I’d expect LibreOffice and any Microsoft Word version other than the exact one used to create the poster to mangle the formatting differently. Been there, done that.
