Seems to be a butterfly or bowtie antenna with a reflector.

>>1667735
Could be used with a RTL-SDR for directive reception. You can determine the wavelength by measuring the butterfly end-to-end or the distance to the reflector.

I need help fixing my toilet. It wont flush correctly. It fills up with water but drains really slow. I thought it might be clogged but one push with the plunger and it drains normally. I then try to flush it again and it fills up and drains very slowly. What do I do?

>>1666494
You're a moron.
The speed of water entering the bowl affects bow it flushes.
You can pour 5 gallons into the bowl at a slow rate and it will never "flush", it will just slowly drain-off the excess amount of water.

$20 say the flush valve isn't opening all the way and water isn't filling the bowl fast enough.

Had this issue. Found a small plastic bottle had fallen in and was caught in the trap. It would float and spin causing your exact problem.

What could be more normal than that? Buddy runs a dealership, when I'm doing their autoglass he tosses me a branded shirt. I've got one from autobody shops my buddy's run, welding shops, and then admittedly state police shirts I buy from a clambake because it supports them. Not sure how any of that isn't normal.

What's definitely not normal is a grown man making sure what he wears is hip and new.

I want to try something similar but before I do, I want to know if it’s retarded or not. I want to take apart an old phone I have and just strip it down to the charger port, MB, and the output to the battery. I want to connect a cable to charge the phone like you normally would, but then take two extra wires and solder them to the output to where the removable battery would be. Using these two wires, I’d charge similar Lithium-Ion batteries similar to the ones the phone used to charge. Does this make sense? Would it work and charge my batteries I could use for portable projects? I’m no electrician or circuit expert but in my head it makes sense.

Hey /diy/
How do I change the water filter in my tap?
It's one piece with the filter up inside, and nowhere to twist it out.
Do i need a tool with a lot of ''pins'' or what am I missing?

That's an aerator, also known as a water saver. Mixes water with air to make is appear as if more water is flowing.
Normally there's two indents where you can jam something and twist, but I can't see nothing behind all that lime. I suggest you put a plastic bag filled with vinegar around it and leave it overnight, it will get rid of the lime.
>>
Hydrogen peroxide will also clean that out

Thank you! I will try vinegar first, and try to look for the dents to screw it out.

It has teeth at the edge under the goo.
The faucet came with a plastic "wrench", usually blue or yellow, a combination of a thumbscrew and a pipe with teeth. If the person who installed didn't leave it behind under the sink or in a drawer, usually small needle nose pliers work.
Yours doesn't look like a delta faucet, but the aerator and wrench look like pic

How can I build something like this?

I have a mechanical engineering degree and I want to learn how to actually make my shit move. How do I learn about motors and stuff? I took Physics II and Intro to Electrical Engineering, so I know about current and voltage and resistors and capacitors and inductors and AC vs DC current and magnetism and flux and all these gay things, but I don’t know how to actually DO anything.

If I build a simple mechanism, how to I get him to move? And move at speeds I want him to move at? What do I need to learn about to make this happen? And what about sensors and all that stuff?

What do you mean by this? Where would I have learned about these things? We covered none of it in class.
>>
>>1662892
This is horse shit. You would have learned about how motors work in your EE class, as well as your mechatronics classes (which are both required by ABET).
>>
>>1668613
In the EE class I learned about motors in theory, in the EE lab I learned about resistors, capacitors, inductors, oscilloscopes, square waves and Nyquist frequency and other gay shit. Mechatronics was one of the electives I could've taken senior year but sadly it was full, from what I understand they only talked about Arduinos.

What a shit program. At Vtech we built motors in our EE lab.

>Where would I have learned about these things? We covered none of it in class.
Have you seriously never needed to research anything on your own before? Never talked to engineers from other disciplines? How do you function in your day to day life without being able to do anything you weren't taught in school?

The one thing that would make Bunnings usable is a directory. The staff simply guess which aisle your item is in. Most of them are poor at guessing.
Perhaps if they had a closed WiFi network customers could use to get directions to products in their on-line catalog.
I've suggested this to Bunnings staff only to be met with stares.

accuracy and stability doesn't matter, so use rack+pinion gears and servos or steppers.
you won't be able to 3D print THAT many racks. Go talk to a laser cutting business to get them cut out of plywood for you.

pneumatics would be far, far, noisier. Fucking christ, even the valves for pneumatics are noisy as hell.

not really. Fuck you can even run em' directly off of logic level voltage from an arduino. Pneumatics you have to do some crazy as fuck control cause air is compressible.

Google vicec article about it:
So what makes inFORM tick? Tangible Media Group's Sean Follmer explained that the system uses a depth camera (in this case a Microsoft Kinect) that captures both the depth image and the color image of the remote participant's hands. A second RGB camera captures the participant's face. These images are then sent over the network to the inFORM system. From there, inFORM's system functions much like the sliders on an audio or film mixing board.

"Basically, what's going on with the inFORM system is that we have 900 actuators that are slide potentiometers used in mixing boards," said Follmer. "These have small motors on them that move the controllers up and down the sliders, while simultaneously recording their positions." Micro-computers read the pin's current position, then change that position based on where it needs to go next. All of this is updated extremely quickly.

>>1666316
Winner winner chicken dinner

Pneumatic is the most retarded thing I have ever heard. Imagine precisely positioning a pneumatic actuator, then trying to do it repeatedly on an array where the pressure is fucking all over the place. Fuck. That.

What a waste of money this project is though. That's where your student loans are going. Incredible.

Dig out a 2.5 foot wide by 2.5 foot deep hole (or however deep) using a concrete footing mold and footing anchor. While the concrete is still wet place in 1/4 thick structural steel rectangular tubing and float into place. make sure the steel tubing is the correct diameter to accept a an El cheapo plastic mailbox.

the jack ass will total his front or back end by running into your bollard you placed into the front. and will have to pay you for damages Other option is build a solid concrete form that holds the mailbox.

Yes and it means you don't know what's legal. You have to take the most extreme view all the time until case law protects you. If you want to be safe.
I don't get how you can even pretend it's a good idea. It's a concession for practical applicability of law. The people who put them in place are stupid so they can't actually write them carefully. One of the big reasons you have laws is as deterrents and if you don't even know what laws apply you won't have a deterrent. Or they're overreaching deterrents.
It's also undemocratic because you've not translated the politicians opinions well if they need extra subjective interpretation.

If we had a much stricter system where a computer could actually tell you what's legal then you'd have way more freedom. You'd never have to question it. You'd simply ask the very same engine that would judge you. The courts role would be to actually try new facts very carefully.
You wouldn't punish those who have no way of knowing they were breaking the law. Because if a court is required to determine if something is legal then your average Joe doesn't have a chance to determine it alone.

That's more inline with the supposed standards for guilt that these systems employ as well.

You also seem to misunderstand English common law BTW. It doesn't mean anything that a court hasn't decided on is legal. It just means that they're favoring precedence. And that requires you know the relevant case law which means you need a lawyer because they don't even build proper relational systems. Musicbrainz keep track of song relationships and relevant facts better than lawyers keep their cases organized.
