The printer would ID and let anybody anywhere dump stuff into it directly via wifi. Was never sure I managed to turn that off entirely, so I had to keep the printer turned off instead. I do SUSPECT who the perp was ... fortunately he grew up and switched over to loud hot-rods instead :-)

Oh NO NO NO ! THIS protocol was made for "convenience" and works (hopefully WORKED) entirely within the printer. The IDEA was to make it hyper-simple for people in an office to connect direct to the printer, even by wifi. Didn't matter if the router/main-PC was on or not. If I can find the manual I'll report the exact protocol. The printer is now on the JUNK pile ... leaks blue toner to the max. NOT worth trying to fix. Got a new color-laser all-purpose unit - do NOT enable anything 'net' however. Use thumb-drives to xfer stuff. Hmmm ... gotta look up local JUNK services to take it, and a bunch of other old stuff, AWAY. My damned house has 3+ generations of STUFF inherited inside it, the junk piles are getting large .... have a VIC-20 buried under there somewhere, Sinclair ZX-81, Apple II, bits of a DEC-based H-11, even one of those Radio-Shack "original laptops" meant for news reporters (with actual Bill Gates code inside it). Never mind all the crap from Weird Aunts. Wow ........ No, not gonna bother with e-Bay - don't like it. Money paradigm is a bit iffy for my tastes plus I'd actually have to pack/box stuff and take it to UPS or FedEx or whatever ......... Can't even LIFT the H-11 dual 8" disk unit anymore ......

As said, power hogs. Many microcontroller-based units let you shut down most every bit of hardware on the board and put the processor into a super-efficient idle mode awaiting an interrupt. Not so with the PIs, they're closer to "traditional computers". DO have some watchdog routines for a few of my PI programs, running as little daemons. The easiest approach has been to have the pgm touch a file every x-seconds/minutes. If the watchdog finds a too-old date then do something drastic. These watchdogs can literally be half a dozen lines of Python, depending on the IQ needed. Stupid, simple, EFFECTIVE. > >> Now STARTING a Pi from scratch a few times >> a day, THEN you need an external timer device. >> >> Microcontrollers, most have low-power libraries >> that 99.99% shut 'em down until there's an interrupt, >> perhaps from a time chip.

The DS-3231 chips are just great, very well temperature compensated, accurate as hell long-term. Some say the newer MAX-31328 time chips are even a bit better. I did lots of 'field devices/dataloggers' for awhile and accurate date stamps were very important. Also the chips DO have 'alarm' functions you can set just before yer board shuts down ... 'wake me up in 30 minutes' or similar. A naked wake-me-up chip with just a few extra transistors could indeed be used to wake up a PI or even something bigger. Look into 'solid-state relays', hell, you could turn on a whole house/factory :-) >> I used a lot of Ard 2560s for solar field devices. >> They have low-power libs and reduce to seriously >> low current draw.

Oh, dealing with sensor inputs in electrically noisy environs ... if possible try optoisolators. The LEDs require CURRENT, not just voltage spikes, to light up. Made some automotive/ag devices, some had 'pony' motors that gave off noise like mad. Optos were the salvation. They don't work with high frequencies, but for devices that mostly send 'pulses', low-baud serial and such ... Higher freqs ... unintended HF/RF coupling between components/stages creeps in. Nothing is as easy as it first seems :-)

Depends on your definition of big. The V-Strom's battery is 6"x3.5"x5"h and is easily recharged with a $40 battery tender. The DR650's is even smaller but it's still in the bike so I can't measure it.

You still have to buy the batteries. Likely some restrictions on those. Not a bad thing however - if you want to pay $227 USD. Now *I* didn't need 200 watts, more like TWO watts. That's still mostly "do it yourself" territory.

The prob is 'application' - HOW would you use the thing ? This could complicate any commercial offerings. There ARE some odd things like 'emergency radios' which combine a solar panel and battery charger and voltage regulator. They're mostly not very expensive. Crack 'em open ..... AND you can play tunes :-) Oh, 'solar-rechargers/power-banks' for phones and such, many are reported to be very UNSAFE, prone to fires. Little/no regulation or safety features. Sorry, $19.95 won't buy you everything ....

It worked, if you had 4 days to spare in southern Arizona. The slow charging was probably a GOOD THING, relatively speaking ... would not cook/explode the batteries. NiMH batteries are even worse than NiCad ... you literally have to monitor how HOT they get. When the temperature suddenly goes up, they're fully charged. LiPo ... slower IS better, 95% IS better than trying for 100%. The damned things LOVE to explode. I've seen tech stories that like HALF the LiPo batts in the USA are factory REJECTS. HAD one explode in my office once ... it hadn't been recharged for months. Barely BRUSHED it with my arm and it went off. Big crimson flames, massive noxious smoke, small burn on my arm. I just *really* don't trust the things. Have some big LiPo batts for large drills and such ... I charge 'em and then KEEP THEM IN THE OVEN (which I never use for cooking). If they explode, perfect heat-proof place. Hmmm ... when I retired, a fellow made a 'character' reference - upon seeing me just calmly watching the battery spurt huge flames. Hey, nothing to DO about it after all ... ! :-)

In the end with the nano timer I estimate about a years supply on 3 x AA. Good enough, especially as it should email me if the battery gets low. Or if no signal arrives at all -- A lie can travel halfway around the world while the truth is putting on its shoes.

DOES show a number of "cells" ... but not the ESSID of my extender for some reason. In theory, this sort of data could be used by a relatively simple daemon to switch back and forth to the 'best' signal. The old CL stuff is fine ... but can sometimes be replaced by half a dozen lines of more-comprehensible Python.
