This is partially true. Connectivity is better than most people imagine, even in places like Madagascar (was something like the fifth poorest country recently?). We had 4G in the middle of nowhere and yes, it's cheap for Westerners. Ho

In Oz, you could try Element14 (which is Farnell rebranded). $50 for free shipping, or $15 under. The DS18B20's are about $7 on there too, so that's the correct AUD price. Also check out RS Components Australia. They often offer f

You can buy those metal sensor sheaths separately. Search for something like "rtd sheath metal" e.g. ebay #162885663706. $2-3 for a set of 5. Then you pot the sensor with something thermally conductive and waterproof - waterproof

The legal situation is ultimately whatever your company signs off on. If you get approval - which may take some bureaucracy - then you're off the hook. There will be limits on what you can work on, and it might have to be nothing to do

Philosophical question - if you code in private and never release it, do you care? Is this for personal fun, or are you portfolio building? The problem is usually when you want to assert copyright, not that you can't do side projects a

The obvious way to assess if availability is the factor is to look at open access publications. Elsevier (unsurprisingly) say it makes no difference [1] and there are confounding effects which are stronger. For example, papers with code ten

The problem is that people will often grant that kind of access, particularly to pirate software. For example modification of hosts files (to prevent phoning home) is generally something that lives in /etc which requires sudo to edit.

You can get a 1nm resolution "science grade" spectrometer for under £1k - I used to design them [1]. You can also buy used ocean optics kit for very reasonable prices on eBay (a few hundred for a USB2000 if you wait). Or make your

I used to do this in London when I traveled there for lectures as a PhD student; our lab wasn't in the city. So as not to waste two hours of traveling for an hour of class, I'd go and see movies afterwards. It was great - you coul

The South Pole is a particularly interesting case. Clearly the Pole itself is 90 South and the choice of longitude is arbitrary there. However, Amundsen-Scott station, which is a hundred odd metres away, happens to be at ~140 E (89.997553 S

Does the NUC support hardware acceleration? Otherwise you could just use a Pi 4 for this and run all your cameras through gstreamer, which supports the ops you want - I think you can even do PiP. One thing I don't know though, are you

I've spent the last couple of years working on an edge multicamera system (drones). Even at a fairly low resolution, eg a 2MP RGB cam and a VGA thermal, you run into problems. Depends somewhat on how much cash you have to spend on the

[For kids] I think you can rule out any online game, or any gambling game (both will be age restricted). Saying that, teaching kids how to play cards is probably worth it. Board games are generally good for mental arithmetic, particularly M

On the island bit - the travel situation is quite different to NZ. We have a lot more traffic for business, multiple busy airports, a rail link to the Schengen area and cheap access to international travel. We probably had a lot more route

Recommending there to be no glass in the environment makes sense for liability, but I would have thought a few ultrasound detectors would be sufficient for gross collision avoidance e.g. to avoid walking into a pane. Similarly forward/

Here you'd probably want to use local automatic weather stations (AWS), which are a superset that includes major airports. There are lot more of those around London than just Heathrow. I imagine NOAA has a similar setup. https:/&

Double insurance isn't necessarily illegal on its own, but some insurance companies will say it's a policy violation to do it. Claiming is another matter. Double dipping car insurance is definitely illegal in the US. That said, in

Lots of reasons why you might want more local though. My local airport is more than 10km away (but there are other monitoring stations). Pilots and controllers assume some uncertainty because even within the airport perimeter there will be

PIC extreme low power (xlp) is ridiculously low - at least an order of magnitude lower sleep current (9nA) than ARM equivalents. They also have very low uA/Mhz, but some ARM chips are approaching or exceeding that (eg SAM L). There&#x2

Yep, they just cracked and broke. Maybe more of an issue with the TWSBI because the reservoir is part of the pen. Maybe environmental, but I don't live in a particularly extreme area. I never had an issue while I was using them regular
