Has anyone installed home security systems in their houses? what do you recommend and do you regret it?>inb4 gunI come from a country where firearms are illegal unless you are a farmer. I am a bit unsure about the cheap camera's which connect to your phone (additionally I am a bit of a snob and would rather spend good money on something which lasts) any recommendations would be great I am open minded. Definitely prefer hard-wired electrical devices, could have it installed by my electrician relative so installation price is not an issue.
>>2973209Become a farmer then
>>2973473>install hidden cams that look UP near front door, so you can give local cops a FACE pic, not pic of top of some punks HoodieClever, I might have to look into this.Regarding the possibility of a camera getting ripped out: I don't know if other brands have this feature but I use >Eufybattery cams which have an anti-theft alarm so they'll start making a very loud and obnoxious noise if they are moved from their position. I know it works because I forget to disable the fucking thing every time I take them down to recharge them.
>>2973209Home Security is a necessity from where I'm from, do I regret it? No, neighbors usually comes and asks footage from me if there's an incident that happens that's in range of my cameras.>what do you recommendIt really depends on your house, just go with any CCTV as long as it has it's own DVR, can't say whether you should go for an analog or networked ones, it'll all depend on how you'll be setting it up. I'm already using bullet type cameras, wanted to experiment using a cheap PTZ camera I found at a flea market, it says it a lenovo brand but looking through it is actually from another chink brand Jooan, currently struggling to flash a different firmware onto it as the PTZ doesn't respond to any of DVR I use, even tried using ODM but to no avail, and no I ain't installing that chink Cam720 shit
>>2973476>>2973531Ausfail, fairly easy/simple to get a firearms license. You are definitely not allowed to store the firearm loaded inside your house, especially if you live in suburbia. Firearm stays locked in one cabinet, ammo stays locked in another cabinet until you head to the sporting range. Firearms are not to be discharged in city/suburban limits outside of firing ranges. Rural/semi rural farmers etc are allowed to use them on their properties for pest control etc.
Can't say I've done it, but it doesn't seem like rocket science. Most home security systems these days configure themselves and run on WiFi.A lot of people air tag their car and get a Google door cam, kind of cursed, big brother tech, but people do it because it works. Putting remote opening devices and key locks on sheds and external gates is easy, putting bars or security screens on doors and windows isn't particularly hard. Motion sensing lights are a no brainer.Then you've got soverign systems which run if there's no power or internet, battery powered cameras, lights. Wired cameras that can't really be hacked.

>>2973982>And you lived closer to work.Not really, most of the prosperity of the period was built by expanding housing to suburban sprawl, but having most major businesses operating out of the downtown hubs.So to support that they bulldozed middle-class black neighborhoods to build freeways connecting the two.
>>2973994I'll add as well that because of the way suburbs were designed and zoned, you often had to drive a lot further to get out of a neighborhood even with the same "crow flies" distances similar in-city grid streets have, and suburbs don't have intermixed residential and business areas that can be walkable, so just basic shopping also means having to drive a lot.
>>2973997The post-WWII American Dream right here. Sure, everyone's house looked the same, there was no landscaping, insulation in the walls, grounded outlets, or eves to keep the sun and water off of your exterior walls, but at least the darkies couldn't move into the neighborhood. We made sure of that. And, yeah, there was a lot of asbestos in everything, but everyone smoked 2 packs a day and that was likely to kill you sooner. Lead in the water and paint? Who cares if your kid ended up a little retarded. The world needs ditch diggers too.
>>2974077My hometown has a rat maze burb, not nearly as large or cookie-cutter, but it was built in the 60's and butted up against a Nike missile battery site. By the time I was in high school it was long defunct, but it was also known that a few miles away was one of the dish sites. The barracks there had long been torn down but the huge, vertical-facing dish was still standing, heavy-metal paint flaking away from the exterior. They demo'd it at least a decade ago and the property seems to be up for sale (most recent Google maps images). We used to get in it, smoke weed, drink some beers and stare at the stars because the light pollution was minimal there. One friend with bigger balls than me brought his skateboard into it. I still wish I'd yoinked some of the old hardware from it, if only for the cool factor, but it was just the "satellite dish" to us until I looked up it's actual purpose years later.In hindsight there was a much newer, smaller, black, wireframe dish on the property that used to turn on a motor. I never saw any security cameras but now that I'm thinking about it us idiots were probably all being recorded on what was still US Military property. Oops.I feel kinda bad 'cause the last couple generations don't have any cool shit like that to explore here anymore. It was "hidden" at the back of another neighborhood, surrounded by woods. It's too built up, populous and surveiled for kids to just climb the local water tower or whatever with the sixer they talked the local wino into buying them. Hopefully there's still some cool shit for them that I just never knew about.On topic, HF ran a 3-day 30% off $10 or less ($20 or less for ITC) with a 5 item limit. I didn't see it until the last day, yesterday, but got my hose pliers, the indexable ratchet in 3/8, their silicone cap/plug set, and their hand-pump transfer pump. Gonna take my old cheapo soldering iron, some fittings and a mason jar to rig up a smoke tester that I can hook the pump up to.
New Japanese saw, folded over 9000 times!(I got this one at some action of a defunct company and I quite liked it, but it was badly bent so I wanted a new blade. Turns out, a replacement blade is more expensive, than a whole new saw! Sure, most of the money is in the blade and not that plastic handle, so I wasn’t expecting like half price, but more? That’s quite retarded. But I digress. I quite liked the saw and the fact that it’s a jap saw, from a Swedish company with a non-web handle didn’t bother me. Turns out, it was made in Japan all along!)

>>2974198It's the unforseen plague of our generation. Previously it was Radium, then it was lead, teflon, asbestos and now it's microplastics and plastic fibers.The disonance is actually poetic; some brainiacs balls deep in materials sience developed a substance one step from being poisonous and two steps from being explosive - that's pure chemistry; indigestible by virtually all organisms on earth, non-degradable, naturally alien to this planet. And then there's bunch of neet retards who want to fuck it, because it can be molded into shape of a woman.
>>2974224Theres food safe silicone you know. >>2974128Youll want s positive mold and lots of gypsum. You could print the whole mold but then thered be layer lines do im not doing that anymore. Dong forget the releasing agent and maybe some white glue to make the gypsum stronger.Also for a full doll youll want to buy from alibaba since youd have to get in bulk.Ill get to the robot eyes snd eyelids next soon enough.
>>2974249yeah but silicones are expensive and making mold takes time and skill, making it out of ABS should be fine I think.
Normally I'd point you to Brick In The Yard for their silicone videos, but they've made the best ones members only. Still worth a gander: https://www.youtube.com/@brickintheyard/videosPersonally, I like the Platsil Gel silicones. You can find them on Amazon.
>>2974392The way they do it is very laborious and sculpt it with clay the traditional way. Its much easier to 3d print a positive and use gypsum to make a cast. If you want it to be hollow I've heard of something called slush casting. Don’t forget the white glue trick for sturdier molds.Anyways my 3d printer is broken atm but i can still get the screen eyes working…

>>2973497Why do you ask? Are you getting bug bites at night? I’m gonna break you heart and tell you that it’s bed bugs. These little mites exist on practically everything already and don’t cause bug bites. Not really. I realize I’m doin an awful lot of assuming here, but if it is bed bugs, an exterminator won’t do shit until you find one of them and put them in a plastic bag. When that unfortunate day comes, tell them you want Aprehend treatment. It’s a fungus that eradicates them by latching onto their bodies and having them bring the disease back to their nesting areas. It is devastatingly effective, and I wouldn’t recommend any other treatment on planet earth. It does take a couple more weeks to fully kill then all, but once they’re gone, they’re gone for good.

>>2973923The window in the EPROM chip is used to erase the memory (sets it to all 1s I believe) so if you write all zeroes and expose it to an image, you’ll be able to read the image back from the erasure pattern. You could just do a fixed exposure and read the bits afterwards, but I’d read it continuously to see how long it takes each bit/pixel to change, and use that as brightness information. Arguably you could extract temporal information too, making a video from all of the pixel changes each sample. It will be very slow though.People have done similar things with DRAM chips by removing their lids, but they’re much faster. Because DRAM cells need to be refreshed constantly to keep the data stored, if you shine light on the cells it will cause them to drain light faster, and so flip their bits faster. I think. Probably pretty tough to delid a modern epoxy encapsulated DRAM IC without breaking the bond-wires though, I’m guessing they did it on ceramic or metal hermetic packages, the ones with the gold soldered-on lids.
I am intrigued enough by the new PIC32CM PL10 series from Microchip to have the dev board on order (and I already have some chips but my jtag tooling is old and crappy enough that I need an adapter for SWD) but besides the neat factor of having an M0+ core and AVR peripherals and pinout wth the weirdness of PIC32 branding, I'm not sure who this is really for. If I got stuck with sustaining work on an AVR design and needed to move to a more modern chip, I'd just go to a more modern AVR. If I were doing a greenfield design, I'm not sure I would pick these over SAMD or STM32. But they sure are neat. It's the sort of thing I would have expected in the PIC32 line maybe two years after the Atmel acquisition, not now.
>>2973992Micron made a windowed DRAM chip for basic imaging back in the eighties. It was a thing even earlier than that - I remember seeing the trick in "build your own robot" books from the seventies.

Is there a proper way to remove baseboards from the wall without fucking up the wall and breaking the wood into pieces?
Utility knife, 5-in-1 tool, trim puller like >>2972776, mini crowbar, putty knife. Cut paint and caulk to free the board from the wall. Identify where the nails are and work a tool like the 5-in1 or the putty knife behind the baseboard. Go down to the next set of nails and do the same. Very gently work the tool back and forth, on the nail, to pop it out. Put another 5-in-1 against the wall to protect it from a trim puller or mini crowbar. It takes time and you need to be gentle. Gotta work each nail down the line. Gotta get as close to the nail as you can when you stick your tool behind the baseboard.
>>2974287Also, you aren't gonna be able to protect everything perfectly. You will need to do some sort of repairs. The wall will be easy enough to touch up once you get the board off and you shouldn't worry about minor damage as long as you can keep your lines and your colors consistent. It's baseboard, so usually only a handful of areas in the house will be high visibility. Most people don't look down there. Excessive nail holes in the trim will probably be your worst offender, but at least you can put some colored putty or some wax to fill.
>>2974286It may share the same color, but it won't act like it and the grain will give it away. Old growth is in a league all its own. It is so much more resistant to everything and it will sit on the wall much differently over time. If a piece of old growth is still straight, then it's gonna stay straight for another 70 years. Young stuff will have a mind of its own. The only con to old growth is it can be brittle and prone to splintering.
>>2974289It's just baseboard. Fir is included in SPF. This isn't some elusive lumber.

The first thing a real man does when he gets a new angle grinder is rip off the guard and toss it in the garbage.

Based on your description though, it sounds likely that most of those will be situations where>I was holding the workpiece in the wrong spot and the tool jumped out of the cutin which case, the guard isn't a strong factor. The guard is for protection from flying material off the wheel -- that means sparks and the occasional exploding disc if you're particularly unlucky or buy shit discs. If you get *cut* by an intact grinder disc, it is almost certainly due to negligence and there's no possible safety feature that can protect you from that.
a boring webm where nothing happens
>>2974311>If you get *cut* by an intact grinder disc, it is almost certainly due to negligence and there's no possible safety feature that can protect you from that.Eh, kind of, because it involves negligently not using safety features as intended, but if you use a handle with both hands on the tool, and you use a guard positioned between the wheel and your body, the thing should be able to kick however it wants and stay away from your body.
This might fit into a /qtddtot/ thread.But oldheads, what should the younger generation do? I already do CNC fabrication, completely self taught, but I feel forever capped at $25/hr. I can also weld, I can fabricate all the shit I cut out, I can do a lot, basically if something needs to be made, I can make it, from start to finish. But I feel like what I can do is worthless because I’m stuck at a wage that will never own a house, at least where I’m at, or even to be able to afford to life alone.

Been thinking of getting into these. Anyone try making them? What's your setup? Everyone I see online is using a particle accelerator but maybe with a high enough voltage a more normal circuit could work?

>>2966250>and everything conductingthe problem with MOT lichtenberg is that insulators can fail and hobbysit wire + pvc pipe surely are not 10kv rated
>>2974266even if it shorts through the insulation as long as you're not anywhere near it it can't really hurt you, the high voltage is pretty localized. At worst maybe it starts a fire and you kill the power and then put it outBut yeah the people doing shit like moving the probes around by hand trusting their insulated stick are pretty retarded, and you have to take it seriously every time and keep your head on straight, the people that die do so because they get sloppy and distracted and then pick the thing up while it's running or panic and do something stupid when something unexpected happens.
What does /diy/ know about insulation a crawlspace? I live in the south and bought this house in the fall, didn't have to touch the A/C for heating or cooling till like December and my power bill more then fucking doubled. I do know the crawlspace is uninsulated, but it has those vents so its "open".I read that spray foam is the easiest to install but might be bad long term because it can trap moisture, but I fucking hate dealing with fiberglass. Would it be a good idea to spray foam in places unlikely to see moisture? The house was designed so all the plumbing is in one small area. So maybe just do fiberglass around there and foam the rest?
>>2971797can you do it with an ir gun
Go to your nearest hvac company and dig out old pipe insulation from their dumpsters, free. It's good to ask first, but most won't care, youre actually doing them and the world a favor. It's better than backed fiberglass because once you slide out the wire plastic wrapped tube, it's all still premium fiberglass left but with a reflective foil shield also. Very easy to handle and very warm. I've insulated many buildings for practically free this way.
>>2973801Then I would recommend doing "crawlspace encapsulation" instead of insulating the floor.You insulate the perimeter walls with foam boards and close the vent openings. You install a continuous poly sheet on ground and walls.the crawlspace now dry and clean connects to the house with some ventilation. Having conditioned space adjacent to the ground will regulate your day/night temperatures. You can also store things down there without them rusting/growing mold.
>>2974275I agree that crawlspace encapsulation is usually better than stuffing insulation between the joists, though the condition of your walls must be considered. If you seal one side of your concrete walls, but they are taking on water from the other side then they aren't going to be able to shed it and you're putting a premature expiration date on your foundation. You usually want a drainage system in place on the exterior side of the concrete wall and even then, if you live somewhere that is wet, you don't really want to *seal* the interior side. Giving the inside some space for air to move across the concrete would probably be good. Doing a gravel-foam cap on the ground would probably be s good way to go, although an actual rat cap should be a consideration.
>>2974296True. The ideal is as in pic related where the waterproofing and insulation is on the outside, keeping your foundation dry and temperature-stable.
Does anybody know how to use a BLDC ( brushless dc motor) to control another bldc? Ive seen a few vids, apparently it is best done with STM32 via CAN BUS ( no idea what that even means).

A cordless 6.5" and corded 10.25" circular saw is the perfect, do-everything circular saw setup. Better than any 7.25" plus anything or those long 4.5" saws.
>>2969469Fine, blade left, but you know I'm right. 6.5" and 10.25" are the right sizes, 7.25" is heavier to run with no practical increase in what you can cut. There's even 6.5" saws now that have more cut depth than most 7.25" saws.
