>>948480 baka. First off, tiles can be anywhere from $0.25 a sq.ft. for clearance ceramic to $30 a sq/ft for real stone mosaic, so that makes a big difference to price depending on what type of tiling you're going for. Same question, for the bathroom, is it a shower stall that you're going to tile or is there a bathtub you won't have to tile space for. Are you just tiling the bottom 2' or are you going up to 5' or a standard 4'? Are you going to tile behind sink, or is there a built in cabinet?

Hey DIYmons. I have a storm cellar that has a nice basement room in it located under the house, kinda like a half basement. It's about 6 ft. tall. There are 2 windows to this room on the side of the house.
I'd like to build an extension onto the back of the house so that this room can be accessed without exiting the building. The extension would contain the stairs to access the basement, and maybe a door to the backyard. The floor of the house sits about 4 ft. higher in the back than the opening to the storm cellar, and the air-conditioner is unfortunately located... Comment too long.

>>947145 Without a shot of what's above your access door it's a shot in the dark here, but you won't get a much smaller stair footprint than spiral stairs. Unfortunately, they would make moving things in and out of the basement room a total pain in the ass, but still kind of possible since you have windows. It would take some measuring, lots of thinking, and maybe a little excavation to make them fit.
If I have a step-down transformer leading to a peltier heating element that I want to control via duty cycle, where do I put the relay?
Do I put it between the transformer and load? Does this mean that the transformer is "always on" and wasting power?
Do I put it before the transformer, so the duty cycle includes the surge of the transformer activation? Will the transient nature of the transformer smooth my square wave duty cycle? Will the constant cycling cause any damage?
I'm a bit in the dark here when it comes to these sorts of high-power... Comment too long. Click here to view the full text.
This is typically done with a Triac on the primary side. I know nothing about peltiers but a recifier and large smoothing capacitor on the secondary side will smooth any kind of inductive kick you could get.
>>948931 You're going to be switching at 50/60 hz if you're using triacs or thyristors. That's the only frequency you would want to switch to anyway if you're using those iron transformers as opposed to ferrite ones used in smps supplies. > So the inrush current wouldn't be a significant problem?
What kind of transformer are we talking about here ? Typically, no - it wouldn't.

Is it true that rust is like a cancer, and if it is present it helps further the development of more rust, or is it just a folk myth?
I'm trying to decide if I should go through the hassle of taking a wire wheel to some of the more seriously rusted parts on an old but good bandsaw, or just spraying down the rust with oil and calling it a day.
>>947864 Its true. The problem is two fold. Rust cause the metal to flake up and increases surface area. That allows more moisture to get near the metal and cause more rust. Moisture also gets between the layers of the rust and doesn't evaporate as quickly, causing even more rust. It also gets under any paint or coating (like chrome) that is protecting the metal. The coating flakes off and more metal is exposed to the air to get rusty. The oil will help but its best to remove the rust and protect it with paint or a wax for working surfaces (like the table of a bandsaw). You don't want to use an oil on the working surfaces because it can stain the wood and discolor it or cause problems with finishes. For non-working surfaces, the bed of a lathe for example, oil is fine because the wood wont touch areas.
I'm trying to design a controller for a reef aquarium so the first thing I want to get figured out is switching AC devices on/off. I've done some research and most diyers use these relays as pictured or the solid state relays attached to a micro but I want something that I don't need to worry about failing or burning down my apartment complex.
I do have a few years with electronics but none really with mains power. Is it realistic to think I can basically make a controllable 8 outlet power strip and not have it be a fire risk?
I've... Comment too long. Click here to view the full text.
As long as you figure out how many amps are going to be flowing through the relays and you have relays rated for that current there shouldn't be a fire hazard. Though, relays aren't really meant to be constantly energized so that may be a problem if you're planning to use them as a switch that's going to be on for a long time.
>>947756 If you lived in Dallas, I'd give you 8 idecs and bases. Look up idec (name brand) or icecube relays. You don't have to have bases, but they make it easier to mount. Those or RIBs are we use in a professional setting 99% of the time. >Track mount relays are the last option, and only use them when space is the primary concern.
I have a somewhat interesting project, which I will share with you later when I am nearer to the completion of it, but for now I need your help.
I have 125 RGB LEDs. I have to controll every one of them individually, if possible with brightness regulation. What kind of a controller would I use? I can imagine controlling 5 or 6 normal LEDs, but 125 RGB ones kill my imagination. That's a total of 375 outputs I have to be able to control. What the fuck would I use?
I have access to a bunch of hemlock logs and a sawmill. I need to cut them all and sticker them up. I don't have a cut list for future projects- I'd like a generic one.
I know I'll be cutting a bunch of posts and beams for pseudo post and beam construction. I know I'd prefer 2x6 for stick frame so that I can insulate better, and/or rip in two for 2x3 construction when I don't need to insulate.
In my head, I should do a certain number (or percentage) of 6x6, the same for 2x6, the same for 1x. Then I'm lost. Is there... Comment too long. Click here to view the full text.
>>945654 Sawing to use. >>945674 2x4 seems to small and only good for framing a stick built frame that won't take enough insulation. 4x4 also not big enough for post and beam construction. Why do you suggest 2x8s? Those, and x2 and x12 are teh ones I'm most unsure of.
So my bro recently gave me a broken MIDI keyboard. He said the only problem with it is that the USB connector (I think mini usb?) broke off of the circuit board. He tried to solder it back on, and it looks like he may have fucked it up beyond repair. Its pretty burnt, the green part of the board is coming up a little, and the actual component has solder all over it. My question: how do I check if it still works? I definitely need to buy a new mini usb because their is solder all over the four little prongs on the back. But I want to check if it would even work before I waste... Comment too long.

It looks like all the electrical contacts are still fine. Those four large pads are just to hold the socket on the board. Cut a USB extension cord in half and solder each of the wires individually. You should be able to figure out which wire goes where with a continuity tester or by looking at the old socket. Then you'll have to find some way to securely hold the cord, because any tension will just break all those solder joints.
>>948252 Wow, I didn't even think about that. How will I solder each wire though? I feel like that is a really small space, and I am by no means experienced. Is it a problem if solder holding one wire in place is touching the solder from another? >>948260 And thank you for the diagram!
My parent's cat decided to piss on some clothes on the floor in my closet and it got on the carpet. I washed the area of the carpet with soapy water and then covered it with baking soda overnight and vacuumed it up today.
I thought that it would be helpful to use a fan to get some airflow to help get any remaining smells out, so I pointed the fan at the closet and turned it on at the highest speed...I keep a lot of books and records and stuff in my closet, so I'm paranoid about any remaining smell lingering on them. I'm wondering if this is the best approach... Comment too long. Click here to view the full text.
>>948701 i'm sorry op but you will never get that smell out it will always be there you can use whatever chemicals, wash it as much has you like, you will still occasionally catch the smell out of the corner of your nose and it will drive you crazy never being quite sure if your stuff is clean.
i'm sorry for cat people, i like cats too, but they are animals. animals don't understand not to poop and piss and puke everywhere.

I'm not sure if this should go here or /o/ but i need some help, i've got a grand am gt 2004 and i'm looking to replace the rear 6x9s
turns out the care has a Monsoon sound system, and these are speakers that have 4 wires on them
i've already changed the stock head unit to an aftermarket pioneer kind
i'd rather not order new stock speakers, as i've already got good replacements and the new stock replacements would be expensive. i understand that if i only use 2 wires instead of all four i will lose some sound quality

>>948610 a little googling gives me info about the cars stock amp splitting the tweeter and sub signals, which is why you have 4 wires. your best bet is to grab a 2/3 way speaker and then cut the tweeter lines then connect the main sub and tweeter separately to their corresponding feeds
but like >>948615 said, since i've got a new head unit, (used a wiring harness for the switch), does that mean i should just redo the wiring for them and replace the wires that go into the harness? cause that seems like a ton of work.
but if i just cut the tweeter lines and sub lines to separate will that diminish any quality? dumb question, but which ones are the tweeter and sub? and also, in OP pic theres... Comment too long. Click here to view the full text.
I am planning on making an automated greenhouse system with some human controlled elements. I recently received a Makey Makey board, which allows you to create human Interface devices simply with strange materials. Thus has inspired me to make something more interesting than a few switches or a touch screen. I am thinking of doing something made of stone and wood or something similar. I want the interface device to look at place in the greenhouse, not something alien and yet be simple to interact with.
Tl;dr help me come up with a unique, durable human Interface device

>>946284 I was thinking of maybe using something like pic related, carving out designs in the bamboo lid in order to represent the different controls and have some sort of metal pin pushed through to conduct.
>>946284 If i were you i'd get some copper (or whatever) wire, route/chisel whatever your design into the bamboo, drill a hole in one of the trenches made, pull some wire through (to connect to the board), solder end of wire to the copper wire and then inlay the routings with your copper wire, hammer and sand flat.
If the battery provides 4.5 volts and the led I want to use takes in 3 volts will that work? Like will the other components (speaker) not have enough power from the led taking in more than usual power?
