I'm trying to find the cousin of my friend. He kinda went missing 3 years ago.

>What is the greatest horsepower electric motor I can get that will run on 110 volts AC at 15 amps?[/quote]
That would be watts, which is volts x amps.

[quote]How about 20 amps?[/quote]
That would be watts, which is volts x amps also.

The bigger e-bike motors go up to 2000 watts or so and are easy to work with. Plus they come with a variable-speed throttle, so you will have a motor that is variable-speed all by itself.

Pic related. This motor is $430 and a controller is about $75. I dunno what a power supply would cost, but they're on there too.

This company is especially good because they have a slogan:
"something not to do now - it will never be done.... forever"

>>1074410
just how big is your drill press?
HSS bits under an inch will snap off or untwist if you run 'em hard enough to stall a 3hp motor.

>>1074410
well, the average 120 socket is 15 amps, so 1800 watts. 1 horsepower is equal to 745.7 watts, and 1800/745.7 is 2.413839345581333. accounting for inefficiencies and losses which according to google is usually about 25%, you can generate approximately 1.810379509186 horsepower from a standard us wall socket at the motor.
long story short, if you want real power youll have to go 240v where you can go in excess of 10000 watts

Pick one

>>1074297
I am looking for where is the best information so I can start learning how to woodwork.

>>1074286
Start with PaulSellers

What type of plugs are on them? They make sensors that detect how much electricity has been used. And then log it back to an IOT hub. They are about $40.

>>1074179
Plugs? What are the sensors calls? Can I buy them online?

Any electricians here who can help?

Oh, and no short circuit protection. The circuitry on that is a hassle too. The LM317 and LM337 can handle have the output shorted for a little while as long as the Vin - Vout is less than 40V. So I guess I would only need some sort of protection between -V and +V

And I will be protyping on veroboard

you can use the 2-diode trick to make sure the output goes to 0V instead of 1.2V minimum. also, ten-turn pots are a pain in the ass. i'd go for the more traditional 2-series pots, for coarse and fine adjustment.

>>1073907
yup, definitely gonna go with this schematic. nice

I think the pots are just a personal taste, I much prefer the ten turn pot

Small education in basic googling :

USE IMAGE SEARCH.

The pic was the 4th pic for 4S-30A.

You better be sure your cells are genuine high discharge rate 18650's, or they will explode.

PS. just in case you don't know, the two parallel line symbols in there are symbols for voltage sources. In this case your batteries, the side with the longer line is the positive.

>>1073385
Thanks and no these are cells I recovered from a laptop battery. I bought this board to not connect them directly to the drill so I'll be using these yeah.

>>1073414

How many cells in the laptop?

If you had 8 you could simply use 4S2P with that some protection board.

1) take flag
2) shove up ass

>>1071977
=/

I'm serious, I now this is a dumb image but I like the idea of flags.

>>1071975
dig holes in the floor

dig holes in the ground below foundation

put in metal poles tall enough to reach your room from the ground

weld in rings for the cords for raising the flag

acquire flags

hang them on the poles

put a fan next to it

stand under it

sing the national anthem

open the door for the neighbour

get killed

become ghost

haunt the place and make the flag wave extra hard

done

That might be asbestos and depending on how much you handled it you may have exposed yourself to substatintial amounts of asbestos that can cause lung cancer years down the line and made the surrounding area dangerous.

That's definitely asbestos. I kinda hope this is a troll post.

Shouldn't you have figured this out /before/ you bought the fucking things?

There is nothing specifically magnetic about enamel coated wire which is why normal people call it enamel coated or simply enameled wire.
People who say magnet wire are the same type of people who say ampacity instead of current (but don't say ohmage or farenheightage or milesperhourability.)

Nothing special with magnet wire, maybe some home made motor. But you can make a bag sealer with the nichrome, or an electric detonator, or a bottle cutter, etc.

semen cake mold

use them as small watercolour palettes for travel purposes for the most part

Sometimes I put things in them, but mostly I make stacks of them on my desk and bookshelf.

Sorry for typos (help use, not,..)

sounds like you want a photo beam sensor as used by garage doors, like these: https://www.aliexpress.com/w/wholesale-photo-beam-sensor.html

as for wiring it to your PIR, we'd lot a lot more information, like schematics of the setup.

>>So, uh what if you attach a phone with the speaker power wires instead rigged to a small motor. then like uh, used the motor to close an electrical switch. Then like, totse use that switch to like turn on one of those dollar store electrical lighters, so you can totally light fireworks. Like I mean turn off the call sound for everything except one number, and like call that phone from, china or something?

Tung oil on guitars is great.
Also be aware that a lot of cheap guitars look really awful when stripped

>>1075758
This.

I've used BLO in the past and got a nice result, but you must realise that an oil finish will almost no knock protection, however the sustain I got with an oil finish was amazing!

You can buy transformers that convert 11vac to 240vac. AUS industry use them a lot if they buy overseas from the US.

They are external step up transformer units, so I would try to find replacements for the internal transformers on your equipment first though.

Jaycar Electronics - www.jaycar.com.au - is the go to place in Australia for the sort of transformers you need, but check on the back of the equipment as it may already have a switchable transformer already built in.

The type shown in the pic above is an isolated stepdown transformer and will cost you between $119 and $419 (AUD) at Jaycar depending on how many watts you need.

You might find better priced transformers here - http://www.tortech.com.au/step-down-transformer-australia/isolated-step-down-transformer

>>1075698

You're probably looking at around AUD300~ or so for a step down transformer for each one.

It'd be better to sell them and buy comparable equipment when you get there.

I would use Teflon tape

>>1075577
One turn of Teflon tape might do the trick.

>>1075581
>I would use Teflon tape
Also being aluminum you could out of round the body to make the threads grab a little better. I would stick with the tape.

Since im first and dumb i will say it depends.

Some will, some wont, some fry.

Research or post motor numbers and manufacturer and shit and someone here can help. Gl.

No difference.

>>1075432
No difference since current will still flow in both directions. But it may be a safety issue.
