I need your help to figure this shit outI bought an ice cream freezer, I need to install a thermostat so I can use it as a fridge to store water. How fucking ever, the freezer comes with a heating element around the frame and a fan located in front of the compressor, I have no idea what turns on the fan or even why it comes with a fan, or why the hell it has a heating element (regular chest freezers don't come with fans or heating elements) since the damned thing only comes with a single turning switch with 7 lvls of temperature (7 is the lowest) I wanted to install a stc1000 thermostat, so I can still use it as a freezer if I want. But I have no idea how the thing works with those extra elements. Pics below
>>1149927>>1149921integrating it its way more complicated, fuck, im gonna make a diagram of it integrated for aesthetics purposes
>>1149935If the digital thermostat fails you just unplug it and still have a functioning freezer.If you want to sell it later you can sell it as an unmodified ice cream freezer.If you 'mod' it, you're stuck with it like that unless you do it in such a way it can be undone.sup 2 U

>>1149928Yes heaters in the freezer is to prevent manual defrosting.
>>1149889>IE: when the thermostat tell it to make coldFreezers don't 'make cold', they remove heat. Then you have to remove that heat from the system itself.>ITT nobody understands refrigeration.
Is it possible to make a 2 stroke 6-cylinder axial engine, wherein 3 pistons serve as air pumps for the opposing cylinder?It makes sense to me. One piston functions as a pump to force fresh air/fuel mixture into the opposing cylinder where the actual combustion happens. The first drawing is a diagram of how 1 pair of pumping and combustion cylinders would work. The second drawing is a top view. O cylinders are pumping cylinders and X cylinders are combustion cylinders, with the arrows pointing in the direction of air flow.
>>1149848so it's some convoluted way to put a motor driven turbo on a 2 stroke?WTF?
>>1149848>One piston functions as a pump to force fresh air/fuel mixture into the opposing cylinder...why?Cylinders are perfectly capable of pumping their own fuel/exhaust. Near as I can tell, all this arrangement would do is increase pumping losses in the extra manifold, plus add some friction thanks to the extra cylinder and swash plate.If it's supposed to cram more fuel-air mixture into the cylinder, why would you bother with separate pumps for each piston when a supercharger/turbocharger will do the same thing, better, in less space?
Anyone here made the router lift from ShopNotes magazine no. 121? It seems to be a really popular router lift on the net and looks simple enough to build so I want to give it a go. Only problem is the router lift is designed to fit a regular round router in a clamping system whereas I only own a plunge router which is more of an oval shape. Also my router tapers a little thinner towards the top so I can't think of a good way to modify the plans to mount my router in a clamping system as intended in the original plans. Any ideas /diy/?
>>1149840if you already have a plunge router, take the easy way outfind a crappy table, preferably in the trashcut a hole for the bitdrill and coutersink some holes for mounting screwsmount the router to itadjust depth by changing plunge amount on routerthe only thing you might need to buy is some longer screws, but otherwise, it can be done for practically nothing
>>1149865This is what I'm doing atm but it's kinda hard to unlock it and push it upwards from underneath the table to increase my cutting depth. Sometimes unlocking it causes the springs to decompress and I lose what my height was at. If a router lift can't be done then I'll just keep putting up with it. It's just kinda annoying and I'd rather something that can be incrementally adjusted.
>>1150020I see what you're sayingI basically did exactly what I mentioned, and it is somewhat of a pain to adjust, but then again I'm not using it every daysomething like this might be a good idea: http://www.instructables.com/id/Router-Table-Fine-Tune-Depth-Adjustment-for-5/?ALLSTEPS
>>1150027That looks much simpler! Thanks man, I'll look into this design.

first of all sorry if my english is weird, its not my native tounge, but ill do my best.so i got this KVM switcher and i want to recycle it. i make weird music that is based on heavy effect processed sounds. (for instance a lot of guitar pedals can be used, rack FX units, etc).so i wanted to make this into a weird audio mixer/looper. the order of stuff and whats on and off can expande the possibilities of sounding fast.but im kinda slow today and cant get a concrete idea. but i was thinking hooking a lot of FX loops (send and returns), to be used each with a singe FX unit. so we have Loops, say 8. L1, L2, L3, etc.so... what i would like this thing to do, from the most basic to the ideal (not sure if possible) goals.that it could switch between:1- On/Off loops in a static order.2-On/Off loops in switcheable order.both 1 and 2 are based on a mono input and mono output. no weird routing or panning stuff that will be present on option 3:3-same as above but also having a mono-stereo split somewhere, so for examplesignal in-loop1-splitter-split1-loop4-loop3-out1split2-loop2-loop6-loop8-loop loop5-out2where out 1 could be a hard panned L and out 2: same but R.we can think most FXs have a gain stage so everything can be pasive.im a bit confused right now. also checking the circuit board. i supose this is just a 13 pin switcher, each big switch connects input to output and thats it.for option 2 and 3 i would have to add more individual switches, this would in a certain form, program the 4 main switches.
bumping, is diy fast?
>>1149838not really my thing, but.. i think you getting too freaked on finding a use for what is an essentialy useless POS. The KVM is (manually) switching 4 into 1 (15 - 15 pins) or presumably backwards 1 into 4; selecting an output will spring release the previously selected (?) - idk wtf else you actually can do with that setup, its not especially promising. But maybe someone else might - /diy/ is slow tho, thread be around for a while - no replies after a few days? bump it then
>>1149841okkk, ill see if anyone else drops in. but yes, its basically a 4 position 15 pin switch.so im thinking on using the 15 pins each as single audio chain, swomewhay modified with added shwitches, so i could change through a bunch of audio chains fast. not sure how yet though. thanks!
down to page 5, this is the final bump, last try, thonkssss
Hey guys i'm making a semi-serious rail-gun for fun and I thought I'd ask if you guys could give me some advice/tips to make it great as possible such as effective power efficient configurations for example etc.pic unrelated
>>1149726Ok. Rail/coil hybrid. A magnetic field will react with coils better than ferrous material alone.So shoot iron darts wrapped in coils engergized by a bisected conductive barrel liner. Contact through conductive stabalizing fins. Electromagnets can be cheaper and stronger that shooting permanent magnets.This system can run on timed pulses from multiple smaller capacitor banks instead of one massive charge. Easier to salvage parts.Use ir triggers in the barrel instead of timing maths and start it with compressed air. Could even load each in a modified shell casing with a burst disk instead of a primer. So you can use a magazine and maximize air pressure without complex valves.$.02

What do you guys think of home automation technology?
>home automation technologyi really like the flush toilet, the room thermostat, and the toaster that turns itself off. things that automate the unpleasant jobs we had to do every day.but 'home automation' as presented by silicon valley feels like those enrichment toys they give to animals in the zoo. RFID socks and always-on telephone shopping aren't solving anything, it's a band-aid for incurable boredom.

I have a Vivint system as well as some Alexa controlled stuff. It's cool. I mostly like my door alarms and autolocks. The lighting is just overkill, but I still can't stay away from it. Whenever I remodel a room, I always add automation.
I love it, honestly. I've always had a boner for 'Good evening, Mr. Wayne' type stuff. Most of my lighting, thermostat, my stereo setup, and my window blinds are all automated and voice activated. I'm waiting on various gewgaws and things to set my tub up to fill itself, against my better judgment. >>1149835Protect your shit and it's botnet free.

Does anyone have experience with using Plastic Dip? I'm thinking of spraying my car rims a matte black, but I've never used this stuff before.
>>1149685Don't be lazy op, do this https://youtu.be/9WQiqYlpxoY
>>1149685better get those tires re-balanced after doing that shit...
>>1149756>>1149837Thanks a lot, I'm going to try it this weekend. Hopefully it turns out alright
Its easy to work with. You want at least 4 coats. 1 light and then 3+ cover coats. Yiunwont need to balance after.
I plasti dipped my entire '94 Jetta matte black because I hated the forest green color. Took me two days and about $90 worth of Plasti dip cans but it looked pretty fucking legit.Only part that looked shitty was the hood because I didn't take it off to spray it and ended up with some striping. You couldn't even tell if you were more than 5 feet from it though.
Can someone explain how I would go about getting internet to my shed.I have wifi in my house, and it would be handy to be able to watch youtube guides in my shed when I'm doing things.I've looked on google, but I can't find a simple explanation, and I know very little about routers etc.Pic unrelated.
>>1149827The idea is to both block out unwanted signal, and to hopefully gather more of the signal you want, like in a parabolic dish. Personally, I've wondered about whether or not it actually works, and if a yagi might be better. But I'm not an RF geek.
>>1149679You're better off running a cable. You could build a pair of parabolic dishes tuned to focus on each other at that distance but you'll end up spending more time and money than you would have with the cable.

Fucking Nielsen broke the door on our TV. The peg on the left side is nowhere to be found. What's the best way to fabricate a new one?
>>1149627when did you last adjust these settings? glue it back on who cares.
>>1150116Slap of duct tape over it. Fuck the door. Get on the floor
>>1149673yeah, i'd way rather have a smart tv whisking all my data off to China instead of a plastic door that breaks after 28 years of use.
>>1150144its a not entirely invalid point you have there, desu. But 28 years of a 150-250W? usage CRT, vs prob 40-65W LCD with standby etc, that probably mounts up some. I take you ain't big on HD sports or stuff either.. but, long may your caps hold.The SMART fuckers, manual set their IP to 0.0.0.0 - and even I draw the line at any model with an inbuilt mic, like, fuck that.
>>1150155>but, long may your caps hold.that's another point. The 28 year old TV is user repairable with any decent soldering iron. The components are huge and the boards are often hand-made, so there is much room to manipulate.Reflowing or replacement of SMD/SMT components on new hardware is above the paygrade of even most savvy consumers.Sure, you could blackhole it on the network, but then that cripples almost all of the features on the thing. Many smart TVs will hardly work without connection.You have a point about power consumption ; and that makes me yearn for an industry trend of non-smart TVs with new hardware and technology, but I think that boat has sailed. As for standby power usage : power strip. Old TVs have no data to lose when you unplug them, and they surely can't produce a standby drain when disconnected. Sounds like a power-strip is the superior choice in that regard.
Making Your Crystals Boil the water Stir in the sugar, a little at a time, until it no longer dissolves and there is a little at the bottom Add a few drops of food coloring to the water, if you want colored crystals Add the water to the jar Tie the string to the butter knife Set the knife on top of the glass jar so that the string hangs in the jar without touching the sides or bottom Set the jar somewhere safe Check back in a day and you should see some crystals already growing Let the crystals grow until they have reached the desired size Remove the string and allow crystals to dryYou will need 1 cup water 3 cups table sugar (sucrose) 1 clean glass jar 1 butter knife String 1 pan or bowl for boiling water and making solution 1 spoon Food coloring (optional)
>>1150109Can confirm, just died

This is more /ck/ related, but could you put some extracts in the solution to add flavor to the colored sugar water? I've got green food coloring, and mint extract, and I'd probably use a wood dowel instead of a string.

I have some new potted plants and have been seeing quite a few gnats flying around. I finally took a bright flashlight and founds some gnat eggs. I collected and destroyed about 12-15 eggs. What do I do to stop them? I'm a plant noob and was probably over watering, but I've read to let the top of the soil dry up to kill the gnats, so I'll do that. Anything else? I mixed white vinegar and some dish soap in some bowls and set them out for a few days, 0 gnats caught in any of the traps. Did I not do it right?
>>1149582A piece of yellow plastic smeared with a thin layer of petroleum jelly. Attach to a stick or hang from a thread near the plants.
Those come with some bought soil to absorb water and release it slowly so the plants can go longer without watering. I think you can even buy them to mix with soil.Gnats usually mean overwatering. Let soil dry between waterings. Let it go until plant starts to show slight wilting, then see how heavy the pot is. Use that info for future reference.
>>1149613Just mist it onto the dirt or plant? It won't damage the plant?>>1149696Thanks, will use this.>>1149607I did find 3 little worm looking things in one plant, maybe the eggs are from those and not gnats?
>>1149582those aren't eggs lmao
>>1149582Apply diatomaceous earth as a top soil, at least .5 inches. Also get some neem oil, and spray not only the plant, but the top soil too.
Now I don't have a lathe yet, but having a look at this neat-looking tape measure I thought it looked like a nice simple wood-turning project with which to get used to speeds and feeds. Since this thing doesn't seem mass produced I decided there must be some sort of tape measure kit that you build your own housing for. After scouring the web I only found cheap plastic-case tape measures, nothing at all without a case, not even bulk. I find this a little surprising since there's probably a market for this, like there is in pen inserts.The tape measure doesn't lock; it's just got a piece of electrical tape to stop the spring retracting the measuring tape. A locking one would be more practical, but I'm not picky.Has anyone else found one or had this problem before? Thoughts?
>>1149526Unless you want it beacause aesthetic i suggest you to just get a professional one.>>1149543Cheap plastic is waste of moneyLook for 3M, mine lasted 15 years before I accidentally it
>>1149548I'm suggesting he buy it for it's guts, not to use day to day. Only time I have had tape measures fail is because the spring broke off/through the plastic where it anchors to the body, even the cheapest piece of shit should have a tape and spring that will outlive the wooden body.
>>1149543I was referring to pen inserts as in the ones that you turn a wooden pen for, as opposed to the replaceable ink cartridges. Like pic related. It's not like these pen insets are more replaceable than a tape measure tape, they're much less so in fact.>>1149548Handymen and /diy/ers aren't the only people who use tape measures, there's a semi-substantial market for tape measures in the tabletop community for measuring across the table. You know how much those guys like their olde rustic props. It shouldn't be too hard to fabricate a lock button either.>>1149549That's probably what I'd do for just a single tape measure or two, but if I was to make a bunch then I'd want something a little more economical and less wasteful than throwing out a dozen plastic cases.>>1149550Oh hey, and you can buy springs separately too. Thanks for the tip!
>>1149526Locking one would take some more in-depth fnangling to get working, but if you're after old school they still make the odd wind-up type tape measure and with some polished brass on the winding handle could be pretty nice
My work vrf
Car has some pretty rough rust spots, anything I can coat it in to delay the inevitable? I'm afraid to wash my car, let alone get a little worried when it rains.
First get most of the rust off by use of wirebrush, or a product like CLR.Vinegar works like CLR, but slower.Then either; Apply a rust converter, such as Brunox (EU), or Krust (UK).or Brush in multiple coats of 75:25 Boiled Linseed Oil and Paint thinner.
FluidFilm is good shit. It's no replacement for sanding off the rust spots properly but it slows the progression a lot. Use it on your door gaskets and they won't freeze shut in the winter.
>>1149509you can chemically convert a light surface frosting of brown rust into black rust, which won't get any worse after you oil it or paint it.but you can't stop cornflake brown rust without removing it completely from the good steel. nothing you can apply will stop it. nothing.
So, anon makes black skulls that burn for stupid money. >be me>long story short have log splitter, aluminum foundry, green sand, cardboard and paper shredder for makeshift press.Wtf do i make to get on top of this train and ride it to the next low hanging bridge anons.I make only 2 promises.Nothing will be build from pallet wood or be buried in a shipping container.3 promises on the assumption someone helps out here. Op will deliver.
>>11495171/3 of a ton confirmed
>>1149524Well hell anon thanks. I cant find them now but i thought they were just fire starters. In any case your info would make for a sick af backyard firepit. When i move i want a wood and alsi another gas fire pit. So depending on mood or time or wtf ever i can choose wtf i want. Nothing beats a bonfire but if i get carried away drinking or it gets late it'd be cool to have an of switch that wasn't a garden hose. Making some smaller skulls could lead to a sick tabletop fire pit also. I havent thought much about making my own refractory. Is it much cheaper than that expensive ass castable stuff?
>>1149532Thought didnt even cross my mind anon. Mix up some copper or wtf ever that shit is that makes green fire. A little coloring in the mix and yiu could tell them apart. Good thinking.
>>1149565Meh. Dont wanna rip them off. Just compete and modify. I guess i can if they ever are back in stock. I have several other mold making stuff and skulls and will experiment.
>>114967150 lbs. xx Saggar Clay $1650 lbs. Edgar Plastic Kaolin $20100 lbs. Grog $60Best guess is a human sized skull would weigh about 10 pounds, so yield of about 20 per batch. Ought to be able to fill a medium-sized kiln with 20. Worst case scenario for firing would be about $20 in electricity, however renting a firing could cost you an arm and a leg if you don't have potter friends. Uh, let's say you can cover these things with a pint jar of underglaze at $20. Not including shipping, plaster and mold making supplies, I'm estimating material costs per skull to be just shy of $7 each.Kinda sounds like a fun, dorky project, doesn't it? Most of the effort in molding projects is on the front end.
