    Buy a Homestead

    Wish list? Farm-able land, water preferably running, a woodlot and of course "near to schools , shopping centres and paved roads, but isolated." Best figure out what you need and then start looking. Take some time. Everybody is different so what works for me could drive another person to madness.
  4. Ran into an interesting little unit. https://www.aliexpress.com/item/NoEnName-Null-2x18650-Battery-Charger-5V-USB-5200mAh-Power-Bank-Case-Kit-DIY-Box-For-Phone/32807259884.html It's an unusual circuit in as much as both the micro and "C" USB connectors are directly connected and there is a combination battery charger and power booster chip. So for some UPS applications it's perfect but for a few there is a hidden gotcha. As when it is supplying power the voltage on the connectors is exactly the same as what is there during charging. So while discharging every few seconds it drops the output voltage fractionally. If the voltage doesn't drop a power supply is present and it switches to charge mode. If it does drop then it's providing power and it goes back to a full 5 volt output. Some devices will have problems with that, but for cell phones , flash lights and most electronics it will be fine. What I find useful is that if you are powering something like a 5 volt cordless phone, or a USB powered WWAN to WIFI hotspot you can just put this inline and most of the time it will sit fully charged and not add any load to the system. It also could float on any 5 volt charging circuit and add capacity. With good cells each pack would be about 10 watt hours of storage. For instance a 3 volt solar panel into one of these https://www.amazon.ca/gp/product/B0784SN6H4/ ( that's 10 for $10.76 ) and adjusted for a 5 volt output. as long as the panel is putting out over 2 volts it will charge the batteries and / or run whatever USB device is attached. Those boards can also kick the voltage up to say 13.8 volts and trickle charge a car Lead Acid battery through a cigar lighter , so a battery bank, or solar panel could get a car with a flat battery running in a few hours ( a 5 volt pack would be able to supply about 600 ma at 13.8 volts with one of those, a 12 volt solar panel would be close to 2 amps in good sunlight, but will still do some charging even if partly shaded. )

    The style of screw head is an exact match for early 1970s "theft proof" Cadillac car stereo screws, but being inset the side cutters don't have a good purchase. If the metal is soft enough, dental drills may do a good job turning the two ramp sections into verticals too.

    Large survival knife, or smaller knife and axe?

    Lists at $42 , looks worth while. Silky F180 is the same price. So I may spend a little time deciding. Might not have been up to the 9 inch tree I was removing but most of the trees that knock over are smaller then that, a big Aspen might be 12 inches and a few of the spruce hit 28 inches , but don't have any of those near a trail let alone the driveway. The $250 Silky Katana saw looks like it would handle anything, but a bit of a high ticket item for casual bush clearing. Found a $10 Chinese folding saw too, looks like the same tooth pattern and density, so I think I'll order one of those as a tool bag addition. ( at some point the nylon handles will probably tear off the bag, nearly burglar proof already, at least will slow them down a bunch )

    I've seen good things written up about silky saws, but haven't gotten to test one out. The bow saws are wildly variable quality too. They really do need to be well tensioned and I wouldn't bet on the teeth being properly set out of the box. Still for a $20 cutting tool at hand it did the job.
  8. "Choose the form of The Destructor!" --- Gozer Well the IMR cells are more forgiving on a poorly regulated charger, anything over 4.25 volts doesn't add to the charge. But the chemistry also stores less total energy. You can get all those advantages by just dropping the charge voltage to 3.9 volts but pretty well all the chargers are a fixed 4.2 volt output ( kind of like digital watches used to be adjustable , so you could tune them to within a second a week. Now even the traces to add the parts are gone and your accuracy is a matter of chance ) Aside from that the place to control safety is the discharge circuitry. A fuse ( can be as simple as a 30 gauge wire as the + link to each cell ) a thermal monitor to shut things down over 90 C and prevent charging under 4 C . Any energy storage system is dangerous proportionally to energy density, total volume and speed of release. A 2 Kg pile of charcoal is fine cooking steaks, drop liquid O2 on it and it's the same amount of total energy but the barbecue will vanish in the flash. 2 Kg of yellow powder heated to detonation and the forensics people may have a hard time finding much to identify. A block of charcoal is a much better store of energy then any battery , but the battery is immediately useful and in small amounts. As we get better batteries with higher density storage, the safety problems change from accidental discharge resulting in dead batteries and maybe leaking cells , to fire and explosion. Most of the problems I've seen have been a result of cutting corners on the final use. So if I am going to spend more it will be on chargers and the extra effort to add fuses and breakers.

    Other then day to day pocket knife, the last cutting tool I used, unexpectedly, was a bow saw. Trees blew down across the driveway ( it's 1/2 mile long ) and I was called to work just to find my path blocked. Was about 5 minutes later then usual. Saw lived in the vehicle grab bag ( along with assorted camping in a blizzard and fixing breakdown tools )

    Medications during a SHTF.

    Learning to harvest pancreases and process them for insulin. Easier if you have hogs or cattle that you know are healthy but it's still a complex and temperature sensitive operation also involving controlled PH , centrifuges and a few chemicals that should be well defined. For me not eating also works, but with a limited time to expiry of metabolic processes from other side effects. 😬
  11. Well, what I'd want to head toward is friends, mutual support and basic resources. Probably with a very full truck. But that would also mean establishing new networks. I'll need to give this a bit of thought. Over the years I haven't found many places I really couldn't live if allowed to ( expiring Visas, tourist cards etc. would place me in conflict with the authorities in many areas )
  12. Yes they do drop with use, especially high current use. Salvaging cells, I find new faulty packs ( poor welds etc. ) are often near 2.5 Amp hours per cell. New but very hard use ones can be 1.5 amp hours. Old cells were 1 Amp hour new, and can be down to 600 Ma hours . All still use able just need to match cells to storage needed. They also live much longer if only charged to 3.9 volts as opposed to the usual 4.2 in consumer chargers. that last 0.3 volts doesn't gain much actual storage. Mil spec is 3.9 volts and I'm sure it's a life issue for them too.
  13. Stored at about 2/3 to 3/4 charge I expect the vast majority will outlive me. I have 30 year old cells in fine shape, and they keep getting better. The safeties in laptop packs count the charge cycles and then shut down the pack after a set number. If they were fully cycled it might even make sense, but every drop to 95% and recharge to 99% counts as a cycle, so a "dead" unrechargeable pack with 6, 8 or 9 perfectly good cells. Leaving them totally discharged will destroy them in a few days, reverse charging destroys them right now.

    A little more awake now. ( wrote the last at the end of a night shift ) If you plan to replace the screw ... nuclear option. With a dremmel abrasive wheel worn nearly to the end ( so small diameter ) slice a slot into the head of the screw. Works on recessed screws. If it's all above the surface, a new wheel will cut a full slot.

    Well, sight unseen.... if the sides are at all accessible, a set of good side cutters can grip a screw. Need to be careful to align across the center, pinch enough to make a small dent on both sides ( they may slip off a few times, practice helps ) and then twist counter clockwise assuming a right hand thread ( very good odds ). I'll try to find a couple of pictures of the better tools. Some cheap ones don't align very well, one jaw longer then the other, a grinder can fix that. These ^ will take the most force. but in a tighter spot these ٧ could be a better option. If you can snap a picture, it will help.
