I'm not a cell phone expert. Some, maybe most, recent cell phones should be able to do BLE LR with their bluetooth radio. It is a specific modulation scheme and it does require the BLE transmitter to be capable of particular power le

Good luck with that.

The problem with prepper anything is that preppers tend to be out to justify buying cool stuff they don't need based on exciting fantasies. I am not personally that different, just self-aware. The short preparedness lists prepared by

Good discussion point but the list is a little weak. You can probably google up better. My power was out for a week earlier this summer, so here's my hot take: Once cell coverage was restored I was charging my phone and calling in to

I am a fan. The book is great. You should all read it. I appreciate medical professionals running checklists when loved ones and I step foot in hospitals, and all other attention to quality assurance in medicine. That said, the surgical

Not if you're operating within part 15 limits. But if you're operating your Lora radio as an amateur radio operator, then yes.

I bet! I can imagine festivals being a good disaster simulation. Meshtastic appears to use a simple flooding algorithm which is appropriate to what I understand to be the application - a small group of outdoorspeople keeping tabs on each o

At the application level for Lora, meshtastic looks nice, especially coupled with an android phone and ATAK. I haven't bought hardware for it yet. I assume the approach in the OP would need drivers. https://meshtastic.org&

SCRUM was around in the nineties but it wasn't a big fad yet. The big fad of the late nineties was EXTREME PROGRAMMING, which is still around as part of AGILE.

A book you could have read in 1997, but probably didn't, was Philip Greenspun's "Database Backed Web Sites: The Thinking Person's Guide to Web Publishing".

I am pretty sure there were at least a couple of commercial games and applications written in valFORTH on the Atari 800. Possibly Action! also; for some reason I thought Paperclip was written in Action! but apparently not. There were a lo

I always thought Action! was very crisply tailored to these small systems. It turns out to have been a port of a language called Micro-SPL from the Xerox Alto that (originally) targeted the Alto microcode directly. Atalan and Plasma look n

I could have sworn I'd seen a reference to someone working out or cataloging all known-to-be-useful two-transistor circuits with bipolar transistors but I can't seem to find it now. Anyone know?

A quick Google search will tell you whether the FDA in the US has similar requirements or instead perhaps medical devices in the US are the unregulated Wild West.

I didn't know about the Bottai reform. Apparently the fascists invented middle school, possibly independently. Who knew? https://en.wikipedia.org/wiki/Liceo_classico#The_Bottai_refo... From what I gather, Finlan

It’s neither the best comparison nor a fair one. The Atari was like a little Amiga but the Apple II version captures the spirit of the era better - an Atari port would have looked more like Karateka. As a side note, when I saw Prince of P

Yes. Elenco still sells basically the same thing if that's what you want. The competition seems to be something called "snap circuits" which is way too after my time for me to have an opinion about. Adults and teenagers ca
