Battery replacement is an issue, but is easily solved with good design. I don’t need the thinnest phone that’s difficult to hold, a few extra mm won’t affect my life negatively. I’d rather have something usable and maintainable.
My biggest gripe however is the built in obsolesce of software support life. Perfectly good electronics are rendered useless by the system not receiving software / security updates after a couple of years.
Surely the simplest approach is not to use a wifi ssid that you don’t trust. Yes, mobile broadband is slower and more expensive, but is also more under your control, it is however harder for your boss to monitor.
If I was an it manager I’d probably want to keep an eye on WiFi traffic, even on the open ssid, just to see what’s going on. I don’t trust free WiFi.
If you can’t use 4/5g, and can’t find a suitable firewall or VPN, can you set up a different user on your phone? - and be disciplined in is use.
Have you talked to the school? They may be able to help out, particularly if he’s already in the queue for a diagnosis. Maybe a note from your doctor would support this.
Help may be tuition support, guidance or even some extra time in the exam room - or doing the exam in a different area.
Anything you can do to stack the odds in your favor can help, and the worst they can day is ‘no’, so there’s nothing really to lose.
Finally, though exams are important, they are not the end of the world. They can be retaken later if necessary so try and remember to keep things in perspective and manage the stress accordingly.
Finally finally, good luck to you and your son.
Exactly. Thanks. This is a ‘non-domestic’ application shall we say. Measuring something with any buffer capacity at all should negate the water’s pH, so shouldn’t be a problem, but the manufacturers advice still doesn’t sit comfortably with me. But they should know!
Roller out of a machine for shaping sheet metal?
Has a psion5, brilliant tech. Loved it. The calendar was way ahead of its time, 2AA batteries gave weeks of life and you could just about touch type on the keyboard. If I could get it to synch with office I’d be tempted to dig it out again, it really was the future.
Eyesight started going in mid 40s. Still not happy about it.
Long day!
When I was working in Switzerland briefly, people would speak Swiss, German, French and Italian as well as English all in the same breath. I was told they used whatever word was easiest at the time.
When I was a child we lived in a house in the countryside, so nights were very dark and very quiet. I’d wander around the house in the dark quite often and noticed that as well as peripheral vision, the acoustic of the room gave me information, I could sort of hear the sound of my footsteps change if I was walking towards a closed door rather than an open one. Similarly the air moved differently going from one room to another. None of these senses had enough information to navigate alone, but all added to the model of where I was and what was around me. Of course this was in a place I knew well. When walking outside, I could ‘hear’ the echo of the hedges and walls beside me which kept me in the middle of the path. At the time this didn’t seem unusual. It goes to show that we use all our senses all the time, one helps the other to fill in the gaps.
I’m much older now, the eyesight and hearing are both failing, but it was fun while it lasted.
Want to put £5 on it?
Allows you to remove power from the plugged in device without unplugging it. This provides convenience to easily and quickly turn things on and off and prevents arcing when unplugging. 240V 13A can arc a bit, particularly if unplugged under load, or on older sockets where the contacts have worn. While a little arcing doesn’t do much damage immediately, over time it will cause pitting and make a high resistance joint that will generate heat.
The switch only disconnects the live terminal, but the neutral terminal should be similar potential to earth (depending on how the building is wired).
Truly the king of plugs and sockets. The plugs are individually fused according to the device needs, ergonomic to use and exciting to stand on.
Phalanopsis?
I barely remember my birthday.
If it happened frequently enough, the government would find a way to tax it.
I have a couple of setups, one has poe ip cams writing to a surveillance nvr which looks after motion detect etc. The other system relies on the camera software detecting motion and writing to a Nas.
Both systems are on their own subnet and are firewalled from everything else. I VPN as and when required.
I’ve found motion detect with alerts to be difficult to tune to get good detection without false alarms.
When I started there was lots of smoke 😀 it’s true that you can easily accumulate random stuff, but I still think it’s better to have spares of the things I use than risking running out and waiting for a delivery. Maybe I’m just disorganised.
When you buy components, buy a bag of them. Good for when you let the smoke out of one, and you can have several projects on the go at a time.
Not sure I understand the problem fully, but you want a circuit to operate when you push the horn button, without affecting the horn operation.
Chances are the relay coil is drawing to much power.
Have you thought about adding a transistor to your circuit? It would draw very little current from the horn circuit but should allow you to drive something else. - such as your relay. It would of course require you to do some electronics.
Bedtime doesn’t equal sleep time, but is a good discipline to start making ready for bed and putting devices away. Getting ready for bed at 10, asleep by 11 doesn’t sound bad to me.
