The French always were snippy about their foodstuffs so Roquefort like cheese is often labeled Blue or Bleu. It's like Champagne being called sparkling wine. Over the last few decades there has been less compliance with French quibbles. Damn surrender monkeys... > There's a heinously expensive cheese from Norway that is available here. > > Snøfrisk... it really is exceptional though I haven't seen that one locally. https://www.scanspecialties.com/products/snofrisk-spreadable-goat-cheese- from-norway It isn't terribly expensive although it isn't something I would buy. There are plenty of domestic goat cheese varieties. My favorite has cranberries and cinnamon but it only appears around Christmas. Gjetost is unique and I've never seen a domestic product. https://en.wikipedia.org/wiki/Brunost > My local supermarket probably stocks well over 50 cheese types The Good Food Store may match that. It's sort of a local version of Whole Foods. The other supermarkets have a good selection, some more than others. The specialty cheeses have their own section that's usually in a different area than the commodity cheeses.

While New York State residents get their hackles up if referred to as 'New England' agriculture where I grew up was primarily dairy and apples. You grow what you can. There are quite a few dairy farms in this area too. Jared Diamond's 'Collapse' focuses in part on western Montana. You can grow much besides hay and even that ability is fragile according to him. Of course, he also theorizes the Norse left Greenland after the climate deteriorated because they wouldn't eat fish. The American Anthropological Society produced 'Questioning Collapse', a selection of essays pointing out the errors in Diamond's 'science'.

I have some AVR chips and a STK500 development board from before MicroChip bought Atmel. https://www.manuallib.com/download//ATMEL-R-STK500-STARTER-KIT-AND- DEVELOPMENT-SYSTEM-MANUAL.PDF I should see if I can get it going with the current Microchip Studio or whatever they call the current IDE. First step would be a USB/RS232 dongle. https://wiki.seeedstudio.com/Atmel_AVRISP_STK500_USB_ISP_Programmer/ I'm not sure how this fits in. The only example I've seen uses the Uno pins to reprogram the boot loader. You would have to build your own board to replicate the original starter kit. While the BASIC Stamp, PICAXE, and other devices existed the Arduino made life much easier. You could say it was something like installing MX or trying to get a functioning system with Linux From Scratch.

If there is clean line of sight, a pair of outdoor point-to-point CPE radios (Ubiquiti/MikroTik/TP-Link CPE type kit) is usually simpler than old-style RF modems and can be throttled down to very little traffic. The catch is that the remote end still needs a small panel, battery, charge controller and a weatherproof enclosure, so idle power matters more than peak throughput. If it is not line-of-sight, or if the remote end is just sending occasional sensor data/status and maybe not images, then LoRa/LoRaWAN-type gear is worth a look. It is much easier to run from a small battery/solar setup, but it is not a substitute for an IP-ish link with images. HaLow sits between those worlds. I would check local regulatory limits and the actual antenna options before assuming it beats a boring directional 2.4/5 GHz bridge at only 1 km. -- TheLastSysop <thelastsysop@dev.null> "I survived the great rm -rf / rehearsal and all I got was this .signature."

The LINKS - several variants - seem to be affordable. At 400/900mhz seem to have good range and obstacle immunity. The power budget - always a tricky equation. Plenty of lithium chargers that plug into PV panels. The "Seeed" brand, "LiPo Rider Plus", are the best - no voltage spikes even at low/no demand. My old dataloggers could get by on a 5w panel just fine. However they didn't xmit anything, just recorded to a card. Came out of sleep every 15 minutes. However transmitting can use up a lot more power. Anything 'on demand' like a camera frame will use up more, transiently. > If there is clean line of sight, a pair of outdoor point-to-point CPE radios > (Ubiquiti/MikroTik/TP-Link CPE type kit) is usually simpler than old-style RF > modems and can be throttled down to very little traffic.

My line-of-sight is NOT "clean" ... ergo the interest in lower-freq links. > If it is not line-of-sight, or if the remote end is just sending occasional > sensor data/status and maybe not images, then LoRa/LoRaWAN-type gear is worth a > look.

A few possibly good options - also a few that, on consideration, probably won't cut it. Gotta run a few numbers yet, then I'll decide. PIs are OUT ... massive power hogs. Good microcontrollers give much more control. Anyway, fun project ! Tired of not knowing what's going on at my other property too. If it's on fire I wanna know. If squats set up a camp, I wanna know. If shits are dumping trash, I wanna know. I know a guy with a bucket-truck - for a few bucks he could screw an instrument package to one of the tall trees. Olive-drab canvas strips with an odd splurt of 'primer' brown and it'd look perfectly natural unless you actually climbed the tree. The panel can go on top, angled up maybe 40 degrees, kind of invisible. Have had to use 'disguise' before in semi-public areas.

That's been recommended for the described range and need. Am looking into it. A few other suggestions too. 900mhz band may be the 'best' - less speed but more range and more immunity to common obstacles. Old days (and a few are still sold) 400mhz might also meet my modest needs with even better obstacle immunity. Clearly "live audio", which would be a NICE option, is gonna be just too much bandwidth. Can live without that. Anyway, need a few little weather sensors and the ability to request video FRAMES on demand. That's kinda do-able at about a mile's range without licenses or such govt BS. It has to run on maybe a 10-20w solar panel (easy to hide). Don't need constant data, just kinda "on demand". I've done multi-sensor dataloggers before, know how to code it, wire 'em down to the chips etc. Made a dozen based on the Ard 2560 - good 'sleep'/low-power lib. They didn't xmit though, just saved to an SD card. Worked for many years. Got by on just a 5w panel. Somebody here said their company/group made really good 802.11 RF links - but did not name the maker. Long back such devices didn't even pretend to be network connections - just serial modems. That worked and was less complicated. Linux still has all the needed utils to cope with serial comms.

At $3k I can see why :-) Another old govt/industrial "solution" idiots would vastly over-pay for ??? There are MUCH cheaper LoRa and related to be found online these days. 2.4 is too obstacle-sensitive for my need, but 900/400 can work.
