OK so I need a breaker that will trip at 65A but its going to be at 84V. Anyone know of something that will work? How does different voltages affect breakers. Like can I use a 120v 65A breaker? Will it still trip at 65A?
Since most cheap breakers use a bi-metalic heating element, the trip is at the set current level regardless of the voltage. You can draw it out and do the math yourself, but the resistive metal strip that actually expands generates the same heat due simply to the current passing through it. Voltage in this case is only a reference to the insulation class.
>>940654 >Like can I use a 120v 65A breaker? Will it still trip at 65A?
Yes, if it doesn't have any electronic 'smarts' in it (like GFCI, Arc Fault, etc.) Smart breakers might still work at 85 Volts (how else would they operate when voltage dips during fault). But some operations (like closing) may not work properly.
I i frequently come around here, watching your fine projects. So it's natural, that i come here now for inspiration, hope you can give me some, because i didn't find something usefull googling it.
I have access to a few dozen older and newer skies, Nordic that is, so narrow and with a significant horizontal curve, a few old (70's) and a lot of newer. I work at a store that sells them, and every now and then, we have to trash some of them for various reasons, and now my boss has ordered me to clean up.
So, can you guys think of some... Comment too long. Click here to view the full text.
Hey /diy/ do you know anything about old airconditioners?
My grandmother lives in an old wooden house and she wanted to use the old aircon in her study since it's summer here. I tested it and it seems to run fine, the only issue is that outside the previous tenants attached a hose for the water to drip out through. However no water comes out after 5+ hours of running, so I'm confused if something is wrong. Grandma says it means the water must be leaking inside the machine and into her walls but I can't find any sign of dampness or water under the house... Comment too long.

I have heard of those hoses getting blocked. Take it off and hold it against a water tap and see if water passes. There may be an internal tray filling up.
Had a relative with one of those who lived near the sea. Each year she would take it out, take the case off and rub everything with fishoil. Perhaps an internal inspection is in order to see if wasps have built a nest and plugged the drain or similar.
>>940616 The drip is to drain condensation from the radiator. If the humidity is low enough, there may be too little condensation to form a drip.
It's easy to check. Take the front off, find the radiator, there should be an obviously pan shaped drip pan underneath it. If there's no water in the pan, you're fine. If there's water in the pan, but it's not draining, it's a blocked drain tube. If so, best to fix that so it doesn't drip inside and cause water damage.

Nooooo thank you. Set a glass of ice water down even once without a coaster and the top is ruined. That water ring will be highly visible and never come out. I truly appreciate you /diy/ing something and it looks s lot nice than most lumber coffee tables. That said, I probably would have just got a coffee table for free/spent the $30 for a coffee table off Craigslist. Would look more like adult furniture. The effort you put into it is definitely 5/7 (minus the power strip, need to clean that up) but it's very "bachelor pad-ish"
Hey guys, I'm starting my first project using SMDs. I don't have/want to buy an expensive iron with a needle point. I've seen some guys using copper wire wrapped around their iron tip with the wire filed to a point. Any suggestions/advice?
>>940547 I'm just now getting into it myself (my picks haven't even arrived yet), but I ordered this to start off with http://www.lockpicktools.com/8-piece-set-prh/ Alongside a practice lock to work on.
i pick but i haven't picked(heh) it up for a while. last thread there was a huge shitshow about breakins and nigger accusations for some reason. I've seen several peaceful hobbypicking threads on here so there is no need to justify it to trolls.
I'm a novice out of practice at best, but this is my take on it. get a cheap pick set on DX or something, my first set was supercheap and worked fine. now i got a southord set, hasn't upped my game much 2bh. proper tension rods where the best part of the kit for me.

I got this awesome root system from a job site a few weeks ago. Its been sitting for a while now cause I'm a little lost on what to do with it. Id love to keep it, but hard times have me living at home, so I can't feasibly base my master bedroom around it. I'll probably sell it to make a cool dollar. Possible ideas so far:
Clean, stain, lacquer. Sell as wall art.
Attempt to make a glass top coffee table.
Favorite idea so far, but maybe a lot more difficult. Find a way to run lights along the top and turn it into a sort of natural chandelier. Only concern is transferring power to the root without it looking like shit. Also, it may be like 40 pounds or so. Not sure if that's too heavy to hang.
Are there any refrigerants that are legal and safe to vent to the atmosphere? I have a dehumidifier manufactured in 2010 that I'm disassembling to gather electronics and other components to start a useful tinkering collection.
I am stuck on Samsung LED though (model UN55FH6030FXZA). It has no backlight, passes the flashlight test, but displays backwards text. It also seems to blink 6 times as an error code above the power button. I called Samsung and they said the error code signifies nothing specifically. The person I got it from said the TV was doing some funny stuff before it finally cut off. Supposedly it would randomly display black/white fuzz and some other weird things. Any guesses on what I should replace? Accessing the LED driver or backlight inverter( whichever it is) will be tricky because... Comment too long. Click here to view the full text.
>>940439 I would suspect the main board more than the power supply. If it can light up the screen long enough to display an error, then it seems that the controller is not telling the screen to turn on, so it doesn't. If the error was displayed backwards, that would only happen if the controller didn't know how to output to the screen properly, also pointing to the main board as the culprit.
>>940481 Thanks for the help, the screen never lights up actually. the error code is displayed as the power light blinking 6 times. I'm thinking it has to be the main board too. I'm afraid the power board may have shorted out the main board so I'm not going to install a new main board without changing the power board at the same time. I may be wrong as I have very little experience but I don't want to chance ruining the new main board.
Okay /DIY/. I am making a microcontroller dev board, but it is super compact and you can get fabricated if you like it. (As in the Gerber files and such will be posted online after extensive testing)
I am just having one problem after copious amounts of googling. This connector in this picture. For the love of God what is it called? It will be used for board interconnects but if I can't figure it out I might as well just use an arduino or some clone of it.
