It's a slow board, be patient

This is a slow board. Bump in 24 hrs. Have you got a schematic?

those sodium hydroxide based cleaners are way quicker

What's so "natural" in baking soda?

You can, ifixit and instructables have guides but it usually takes some fine solder work
Having the same thoughts about my nexus 5 after a Chinese cable raped the jack tree point flive is Chinese for 3.7 I guess

Look on ebay for your phone with a broken screen, they are cheap, transplant the entire pcb the jack is connected to. If you use apple your fucked.

The headphone jack is usually a seperate detachable piece from the phone that you can buy for like 4 bucks from any vendor.

Even if it isnt detachable its worth having a look for the same phone models jack piece so it fits snug with the rest of the phone.

Directly behind through the wall Gumby

Theres a living room on the other side of the wall so that is not possible.

>>1013320
Then you can't put it there. You need to drain either directly outside, or into a nearby drain. Run a hose, run PVC. Who cares, we can't do it for you, and the water wont disappear.

"Linear actuator" is the search term you are looking for.

>>1013037
Yes this is it. Thank you so much.

>>1013047
Also try "solenoid"

a pca9685, and a bunch of 18650, 18650 holders, and a voltage regulator. You can mount the control board with M3 size supports.

There is also a fuckton of books out there for using a raspberry pi for robotics. I've built a small one, now I am working on one that will be about the size of a powerwheels. There's a ton of shit on ebay and amazon that is basically plug and play too. I'm more into the building side myself, so I am approaching it from the other direction. All my programming is cut and paste shit.

>I am interested in the programming and mechatronical (servo motion control etc) of robotics and much less in soldering.
There is not much soldering involved in building robots, if you want it that way.

Method #1: you use a rasberry pi as the brains, and it has one camera port on it. you slave a arduino mega to that to act as an input/output interface through USB, to operate motor controllers, to run stepper motor drivers, to make stepper motors turn

Method #2: just like #1, except that you use a laptop PC as the brains instead of a rasberry pi, and you use one or more USB cameras for video input.

>Are there any robotics kits that lets me hookup a FPGA or ARM board? I want to experiment with computer vision and motion control (differential equations etc).
An FPGA could *potentially* be the fastest type of processor you could use--but then, the biggest & fastest FPGA chips cost hundreds of dollars.
Last time I looked, the top-end Altera cost up around $550 USD, just for the chip. Just like with PC CPUs, performance is not free,,,, or even cheap.

Also IMO,,,,, FPGA programming is rather obtuse, especially for things as complex as machine vision.... (...also note that your cell phone can 'see' QR codes, and it doesn't need an FPGA...)
Also the toolchain is complicated; there is a pretty steep learning curve. The cheap $15 China FPGA boards usually *work*, but come with zero instructions.

The Mojo board is supposed to be one of the easier FPGA's to use; it costs $80 from the US seller. https://embeddedmicro.com/mojo-v3.html
(there is also $40 china clones of the mojo, but I dunno if they really work right or not)

As for ARM chips,,,,, the rasberry pi already has an ARM chip in it (I think it's a dual-core now?)--but a laptop PC could have a better processor and way more storage than that.

Not impossible to do, and doesn't need to be expensive either. Kinda a lot to learn tho.

Power source, switch rated for voltage of power source(amps shouldn't matter with an led), resistor if necessary, led, power source.

Use a calculator online to determine if a resistor is needed, all you need to know is voltage, led color, and how many leds. It'll give you a resistor value, and some even tell you where to put it and how to wire leds in parallel or series to fit them all.

option 2 in doubling up the material holding you up, but mounting in option one with cripples under the top piece, and make sure the top piece is mounted in such a way that the load going into it is though it's thickest plane

and good luck having this hold you up i wouldn't build this with anything smaller than 2x4 pieces, though i'd probably double them up and make a frame

or i'd stop being a bitch and use steel 2x2 square tubing and weld it quick and dirty, and never have to worry about it shaking apart

>>1012262

Other than the fact that 2x2 and 2x1(?) trying to hold up the weight of a person, and my understanding that you are only building one of these "frames" I really dont think this will work for anything useful.

What keeps the frame from just falling over from its own weight, two legs of lumber won't do that. Plus I dont think I've ever seen a place actually sell a "2x1" board.

>>1012623
Yeah.. I fucked that up
1) you're right. 2x4s, not 2x1s
2) and this is to hang a hammock for my fat ass

so option 1 is 2x4s nailed together in vertical and horizontal supports

option 2 will likely have eyebolts on the side

you have no recovery after the diodeclipping.
the diodes clip the signal down to their forward voltage.

regular diodes clip around 0.4-0.5 volts, germanium and shottkys can go as low as 0.15v

the simplest fix would be to use 4 diodes instead of two, to in series each way.

I'll see if i cant throw up a simulation to illustrate my point.

>>1012330
i made you a simple illustration.
as you can see, the stage with one diode each way clamps the signal down to +-580mv.
while the stage with four diodes clip at over a volt.

usually, clipping based pedals have a second gain stage to bring the signal up again after the diodes, but I've made a couple of single stage ones like this using diodes in series to get a higher signal.

you can also experiment with different diodes and having one in one direction and two in the other to get asymmetrical clipping.

welcome to the world of diy stomp boxes, have fun!

Shielding isn't really a problem as long as you stay away from electrical lines. If you have to cross them do it at 90 degrees.

RG59 is probably what you have, just run some RG6 to your modem and you'll be fine.

>>1012038
It comes in right at the main electrical box. Plus it needs to run 8 ft on an external wall. It wont get much sun, but it will get pounded by storms regardless, so a good shield is paramount in everything. Again, this is old wiring so nothing is properly shielded, thus new shielding.

I feel your pain, was looking at the quad shielded. Not sure if anything will improve since the wire outside to the house is old as whats inside (not to mention the hobby box crappy cable I ran 15 years ago). Have a booster and their cable their connectors bla, bla. Now I'm going to move the modem to the front of the line in an attempt to stabilize the internet. Paying a megaasston for some BS HD package full of junk and have to kick the damn modem 1x a week and I'll be damned if I let the hacks into my house to butcher things.

I have one of those.
Our wooden chopping board isn't even oiled or anything.

It's just a single big cutout from a log.

No-nothing is the safest way to make sure there's no contamination. If you're worried about bacteria buildup after a few years, you sand it back down again. No big deal because it's already a huge chunk of wood.

>>1011730
>I assume I just get a slab of treetrunk, sand it till its nice and smooth, oil it and then maybe seal it?
pretty much

I would just use some food safe oil

Awesome! That makes me happy, ive seen similar shit for sale at $50 but knowing it's this easy I'll do it.

Now i just have to learn how to use a lathe and i can go mad with woodworking.

Sounds like the encoders went out. Find them, hook up an oscope and see if theyre working when you scroll.

this thing is probably shot. i've take one out of a old bus mouse and stuck it into a usb mouse and it worked okay (luckily the holes matched up).

Is this what autism looks like?

>graduate student
>can't communicate
FML.

Okay. What the fuck are you trying to do?
Are you trying to fence in your yard with rope? What the fuck? Why?

Your fence in the background is fine.
Learn to tie a knot so it doesn't look like shit at least.

>>1011357
>can't communicate
Fair enough, I am a computer science graduate student, so that's definitely a possibility.

Anyway, I am trying to rid the original nasty fence (which was basically rotting) with something else. Digging is out of the question, because literally my entire yard is inundated with stones. So, instead of creating new posts, I went with the eyelet and rope look. I think it looks good, actually.

Anyway, the bundles of rope I bought basically end at the photo. There is an opportunity to do either 1) cut the rope; or 2) keep the rope as is and add something. My question is what does 4chan think I should do? The possibility for something else is also on the table.

>>1011363
If that is your 'rotting' fence in the background there... it is practically brand new. I can't really believe the posts are rotting already.

If they are, get galvanized fence posts and replace with them.

Grow up and stop breaking your things when you have a tantrum?

You can drink it but it won't do much. You need at LEAST two weeks fermentation (like the Mr. Beer kits) and grain kits usually need longer. The air bubbles slow down big time/stop after a few days that's normal but it's still working. Then you need it to set for at least two weeks in the bottle to carbonate. When you bottle you add a little sugar and that jump starts the process again so it can make more alcohol. But this time the air can't escape so it's forced back into the drink as carbonation. So basically no, 12 day old fermentation isn't beer and won't get you drunk.

>>1010843
>in my anger i broke my air lock
What is with people on here and breaking their shit when they get angry? Do all these people just go into an autistic rage whenever something doesn't go their way?
