I'm moving to a new place and I have a lot of cats. way too many. I finally got them all fixed so they can't breed anymore but anyways. the place I'm moving to is a two bedroom and I really only need one so I was going to give the cats their own room so the rest of the house doesn't smell like a litter box but the room has carpet. how do I prevent the cats from peeing or pooping somewhere that might fuck up the carpet? assuming I can't remove the carpet and install something better
>>2799160Crawl under a trailer that has 30 cats living under it. Becomes a gas chamber. Disgusting animals fuckin hate pet cats. Dogs aren't nearly as bad

>>2799203I have 3 cats actually, had cats since I can remember. That's why I discourage retards from having too many cats.Mine are indoor/outdoor, their job is to keep the local rabbit and rat population down and prevent a rattlesnake infestation.I live 1/2 mile from the nearest public road so splattered in traffic is not a concern, they don't go that far alone.Inside I have automatic liter boxes otherwise you have to scoop daily. This also allowed me to cut down my litter costs, I was spending about $700/year just on litter and that was pre covid inflation. The box scoops itself immediately so the rankness doesn't spread on the entire litterbox, makes the whole lot last longer, so spend $200/year instead.>>2799160It's because their shit & piss is more rank than mustard gas. Especially if you don't clean it right away, it just gets worse and worse.>have n-1 cat per responsible household member>if you live alone, you should not have cats,>have n+1 litterbox for every cat you own>have at least 500sq/ft of space in your home for each cat, you can share the space with them, it doesn't need to be a dedicated cat shitting on the floor room>have enzymatic piss remover spray on hand even if they "never" have accidents
>>2799210Id rather have the the snakes, rats and rabbits
Turn the cats out to roam free and fuck up the rodent/bird population.The only good cat is an outside cat.

>>2799496>200mAThat's kinda a lot, big backlight?I'd probably try using a switcher, should be fine.>>2799501Yeah, like that. Those should be input caps just after the power supply, though having caps both near the PSU and near the star ground is probably a good idea, within reason. Make one lot of caps the bulk capacitance (probably by the PSU's output) and make the other lot of caps low-ESR in order to minimise ripple at the star point.>>2799515There's no reason for that, if the signals are single-ended or pseudo differential then you'll be ground referencing the output signal anyhow. If the signals are properly differential then that would need to be supported by the rest of the circuit too.

What type of engine does this thing use? i know its rocket engine but what type of engine can be turned on and off like this?https://www.youtube.com/watch?v=KBMU6l6GsdM
>>2798421Seems to be working pretty well with two states of on or off. Maybe the compact design of '08 didn't allow room valving beyond an on and off. They would also require a very quick reaction time, at the time they might not have been able to get a regulated valve to react quick enough.
>>2798826Some missiles use multiple small solid rockets but it is not what is shown in OP's. They are coming out of the exact same hole.
It's using hydrazine and NTO. Proportional valves tend to be bigger and heavier than a valve that just opens and closes. Response time is also better with an on/off valve and that helps with control loop stability. While engines can be throttled you'll get much higher performance running an engine at the limits of its capabilities. Everyone in this thread is terminally retarded.
>>2798782>Hyperbolic propellantsNO.>>2798815Peroxides are unhealthy but not extremely so. Hydrazine, on the other hand, is a major hazard.>>2799231Had it been hydrazine powered, people would have to wear hazmat suits. In some videos, people were sown in normal clothing next to these.
>>2799518The best thing about hyperbolic propellants is that their capabilities are limitless.

>>2798511kek I live with a tomboyish British girl so my whole life is a constant stream of dirty jokes and innuendo, and while over at my parents' house helping them clean out the garage the other day I accidentally made a similar joke when she found one of those garden kneeling pads. To my mom's credit she found a hoe a few minutes later and said "oh I guess that's who the kneeling pad was for."

Red pill me on water and sewage utilities work.
>>2797394Not him but I worked in that field and it was pretty often that I was using shovels and angle grinders and whatnot in a hole full of wastewater. They like to remind you that it's mostly from showers, dishwashers, washing machines, etc and that's true...but there's still shit and piss in there and they love joking about the "brown trout". And even though there are many ways to setup temporary bypasses that will mostly dry out the work area, often the foreman would just want to skip that part to save some time on the job, or it wouldn't work that well and the pipes would leak on the street level and have to be dealt with, or the soil would still be soaked with it and you had to go in anyway. On top of that, the boots (galoshes) they gave me leaked and sometimes it didn't even matter because I was standing in sewage deeper than the boots. Or when you had to cut wet pipes, you could use a face mask, but in reality you couldn't because it would just get covered in shit and you couldn't see anything. They were pretty good at using trench boxes though so I was never worried about being trapped in a collapse, so there's that. Dealing with the ladders that were sinking into the shit soaked mud was never fun though, especially carrying heavy shit up and down.But maybe I was just working for a shitty company so I can't speak for the field as a whole.
>>2798483Every cable company when they see phone lines in service longer than their company has existed
>>2799074forgot to add, working on new construction (not active lines, before the buildings have even been built) wasn't bad and was kinda satisfying and fun actually.
>>2799074Is there room for growth there or once you're get hired to dig up holes and assist old timers fix leaks and unclog shit pipes you're stuck doing that forever? There are a few job offers nearby and I would like to give it a go for the opportunity to learn and work water supply but having to deal with waste every day will not only become really depressing and disgusting but also embarrassing.
>>2799427Yeah, after about 6 months or so they offered me an apprenticeship as a plumber or something like that, but I didn't take it because I was moving away soon. From what I heard from the guys I worked with who did go that way, it was a hell of a lot better than what I was doing. Much more money, as well. If you decide to try it out, I recommend keeping spare socks in your car.
Need a new corded angle grinder with all the safety features, jobsite requirement. What’s the cheapest decent thing that meets all these requirements? I have an old Hilti that’s great, but no brake on it. I’m suspecting it’s going to be one of the less-high-end Metabos but there’s a ton of models and the filters on the site don’t work well, and it would be great to get something cheaper. - Dead man paddle switch- Restart protection- Kickback protection- Brake- No more than 6”, going to be used in tight spaces
>>2795789I just got one from harbor freight for $14, works great and cut my chicken wire in about 5 seconds. Worth every penny.
Those safety features are meaningless in the context of the consumer safety board and will soon need to be replaced with discstop(tm) technology from TTI masquerading as “sawstop”Possession of older grinders without discstop(tm) technology will result in confiscation and distruction of the tool, and a federal felony with mandatory prison time.

Any way to make a complex model thinner?I told somebody Id do it no problem but now I'm stuck...
idk. add a displace modifier probably.
We have a Red Lion G308A210 HMI on a machine at work with touchscreen issues. The touchscreen will work for one minute and then become unresponsive for 10-20 minutes, then it may work for 1 or 2 minutes again and then it dies again. Power cycling it does nothing. The machine manufacturer wants 12.000€ for a replacement, with a 6.000 euro "core" refund when we return the broken one. Some questions:Is it really the touch panel? The fact that its somewhat intermittent makes me think it may be a board issue. I don't want to fuck with it and then the manufacturer not accepting the core back if the touch panel replacement doesn't work.The HMI uses a CompactFlash for the software. If we buy a used/refurbished one from Ebay, same exact model, will it boot the program with the old CF card in it and just work or does it require further programming?Is replacement of the touch panel a matter of peeling the front "sticker", replacing touch panel (I think it's not fused to the LCD) and then applying the "sticker" again?Will heat on the edges of the touch panel work temporarily?
>>2797994I'm not surprised if heat had an effect, thermal expansion or solder issues were the first thing I thought of. It could just be a bit of solder that needs reflowing. Is it a resistive or capacitive touchscreen by the way?
>>2798388It's 4 wire resistive. Supposedly heat fixes issues with the conductive bars around the edges.
>>2798460fyi a stylus fucks these up
>>2798465All operators use fingers and not stylii. It's just old, and due to the nature of the machine's operation, you have to tap the display constantly Once the label rolls finish, cut the web and tape the ends, tap to deflate the rewind mandrel, remove rolls, insert empty cores, tap to inflate rewind mandrel, tap to advance the web, glue the web to the cores, tap to restart operation. Speed adjustment is required pretty often and that happens on the screen too using a slider instead of a rotary encoder.
>>2798473heh we have physical buttons for the these common functions>t. label machine builderhttps://www.youtube.com/watch?v=4Yf0_WK5o8wOn the CF card, it appears the configuration is stored on internal memory and the CF card its used as additional file storage. However there is a recovery procedure, if your supplier is not a retard, you might find that file on the card. might need a usb cf reader to check that
What can I do with these?
>2798642how do you fuck up like that
>>2791552Egg cartons are fucking expensive. $1 each.
>>2798442>dude uk ackshually I’m smarter because I hoard garbage>*worthless projection*Shut the fuck up retard.
>>2791552Burn them or throw them in the trash like a normal non hoarder would do
>>2798526When the wave (the sound wave) hits the curved surface it distorts the wave making it incoherent thus unable to be heard as "an echo".However what the egg carton does not do is significantly reduce the "amp" or energy of the wave thus there is still *background noise* that is unintelligable.
I have a great working Dewalt DC984 drill but the battery packs are dead. Should I try risk it with the scissor trick or something? It would be a waste to not use this anymore. Otherwise I will just go get a new Parkside set or something on a budget
>>2798890
Had an old blue Bosch 14.4V drill that was working fine, but the batteries it came with all died.These were Nimh iirc. Opened them up and found the cell size written on each OEM cell. Ordered new cells from ebay and soldered those into the batteries in place of the dead cells.I still have that drill and although it's definitely no 18V lithium as far as power, it's nice to have around for jobs where two drills = fewer bit changes. I think I paid around $15 for enough cells to repair 1 battery. Ended up repairing all 3 eventually.
>>2798890> SSRs will eat that no problemExactly. Everything is already electronic drivers.In fact, they could step it up to any arbitrary voltage in the pack itself if they wanted to with 97% efficiency if the collective idiocracy forgot how to design a 12 V motor. Although, they could disassemble one of the billions of 12 V automotive starter motors for some clues.
>>2798916Yes, it’s absolutely impossible to redesign plastic moulds for battery packs. Once set, no manufacturer has ever changed them… not in hundreds of years, anyway… and perhaps hundreds of years to come.
OP here again. I could not for the love of me find a battery adapter that would fit this drill model. I did another full charge of the two batteries I had, then I connected them using two pairs of scissors as mentioned before. I left it like that for 5 mins, let them cool off for another 5 then stuck it back on charge. It's probs too early to say but Atleast one of the batteries has been working without issue over a couple of hours drilling in intervals. Shame I can't get the adapter tho, the ones shown don't clip in properly which means my drill must be even older than I though
How do I buy chemicals? I'm in Japan but these idiots are so uptight about everything it's damn near impossible. I've gotten most solvents I could reasonably need (barring tuolene) but nitric, hydrochloric, and sulfuric acid are all just straight up fucking banned. Best you can get without a permit is 10% of HCl/H2SO4 and 5% nitric acid. Like, it's insane. Yeah I could buy TEN LITERS and fractionally distill over a month (and probably kill myself in the process because retard fingers and earthquakes) but it would cost a stupid amount and take forever.What companies ship to JP?? Even fucking chemsavers won't ship int, and most eurofag suppliers won't ship to JP.What's worse is that even when they do ship, customs is basically guaranteed to fuck me over. The only places I've found domestic that sell anything at all are Matsuba on Amazon and Jikken-kun (hayashi chemical corp on monotaro won't sell to individuals). WTF do I do?I really wanna get my hands on some thiourea but I can't find anyone who sells it.
>>2798505> toluene not bannedIt’s illegal even to *possess* toluene in the center of the world: california.It’s not banned because it’s carcinogenic, it’s banned because they don’t want people to store any kind of fuel. Gasoline is carcinogenic, too, but part of the metallic additives turn it into a gel when exposed to oxygen so it’s not worth storing it.Toluene white gas, xylene, naphtha, don’t have the additives, and they don’t want you to have them.
>>2793680www.freechemicalsforhomeuse.exe.com
>>2798634If you wanna store gasoline for a long time just hit up your local small airfield and fill up some jugs with avgas. Shit lasts forever. I do it all the time for my racecar that has a highly strung out old carbed engine and needs high octane leaded fuel.
>>2793680Make a hobby of building miniaturized chemical factories. Start with Haber process and work from there. Do it all electrically - press a button and chemicals start dripping. Have it all automated with Arduino. Use common feedstock like water and charcoal and air. Put it all on youtube with plans.
>>2798634>it’s banned because they don’t want people to store any kind of fuelNo, it's banned because of muh meth labs.
Lads I'm a clueless shitposter boomer that through sheer persistence managed to pull a job interview next week for a plumber assistant position.

Does anyone else feel intense amounts of rage when watching one of these DIY shows as much as me?I'm a pretty laidback guy, but these shows make me want to assault women and fags.

I decided to under cut my fireplace to install laminate flooring. It turned out okay all things considered.
>>2797104>Can you find even 1 picture of someone who did this?
>>2797113None of those show base board on stone.
>>2797116because that would look like shit. when he said "subtle" I assumed that was his way of saying shoe or quarter round. go ahead and USE THE EXACT SAME METHOD to slap bigassed base around your bricks.and have your eyes checked.
>>2797120That's very clearly brick cut to allow the baseboard to slide under, which is no different than what I did
Still defending your ignorant fuckup I see.No you dont use base on brick, the proper way to run into brick is either buy or make a transition you turtle herder.
What's a good joystick that's directly compatible with an Arduino? Pic-related supposedly has 1023 positions for each axis, but in reality has huge deadbands and maybe has 3-5 real positions. Others I tested are even worse.Has to be under $50 and ideally not require anything but a ground and arduino voltage meter wire. If it's really precise, I can mess with other things.$50 really is the upper limit though, I can't afford a $300 industrial joystic.
>>2798342Skill issue, I am using one of those chink joysticks and it works fine
>>2798367>I am trying to map to servo movement and really would like a hit on every single one of those 1023 positions.First, the joystick is just a potentiometer and does not have "1024 values", that is probably your ADC being 10 bit gives you that number.The joystick won't work for that purpose. Neither your adc nor the joystick's potentiometer (or your hand) will be that accurate/discrete and the value you get will keep jumping aroundWhat you want is a rotary encoder
>>2798367>I am trying to map to servo movement and really would like a hit on every single one of those 1023 positionsyour finger can't input 10 bit precision movement in the joystick.Make your requirement less dumb.
>>2798892Listen buddy, I’m a pro gamer. Do you have any idea what my skill level is like? 10 bits is not nearly sufficient. But I couldn’t get one that can sample into the terahertz for my femtosecond reflexes.I going to plug it directly into multiple QPI busses since PS/2 and USB 3.2 are way beneath my play tier.I’m ranked within the top 95th percentile of all dota players. I also have triple Z rated tires on my honda civic because other tires just aren’t up to snuff.Let that be some perspective for you.
>>2798342you know dogs noses are used for joysticks right?
