Why? Literally just buy some cheap mp3 player off Amazon or ebay. Or use your phone like every normal person.

>>2799904
>Why?
I'd like to do some weekend projects, just for fun

>>2799865
LMAO YOU COULDN'T EVEN FIND /rcg/ even though I told you what to search for. Jesus christ man, you are probably too stupid to fly a drone if you can't find the drone thread and learn about how they work.

I want to plant some fruit trees and berry bushes, the nurseries are quite expensive so Im trying to source them cheaper

>>2799852
I'm too fucking exhausted to weed and water what I have let alone plant something. Rained like a motherfucker all winder and everything went nuts come spring.

>>2799852
I live in Phoenix. The summer hear is no joke and I'm not paying for that water bill.

Heirloom maters. Giving away some of the other plants to my neighbors too. I really wanna start an apple tree and im moving so this might just be the time.

The hallway frame.

>>2799837
May have been that the person didn't paint it with specific MDF primer. If it isn't buggered from water damage you can get resin that is good to fill and then sand down to smooth it out

>>2799795
Luxembourg and you'll never hear the end of German's telling you about why Bosch is quality.

Hand tools, dieter-schmid or whatever is cheap at Bauhaus/batiself.

Alright, so the application in question is electrochemical analysis. I've got an equipment that has precise control over voltage and current and can do all sorts of voltammetry and pulse sequences but it can only go so high in terms of voltage. I'd like to amplify that while keeping the shape and accuracy of the signal so what'd measure off of it will be an accurate representation of the chemical processes happening in the electrodes.
From what I can see at a glance from wikipedia it seems an instrumental amplifier would work for that end and the schematics seem simple enough for me to try building one for experimentation.
With that background on the intended use, can you think of any better fit for this purpose?

>>2799794
They're still listed among other in the last link. They'd be worth recommending specifically too because how can you not recommend building up orders to get free delivery and have stockpiles of basic components because you added 20 bridge rectifiers and 100 1n4001 etc. that one time.

>>2799790
>I don't often hangout here, forgive me if this isn't perfect
Did you read the part at the bottom of the OP that you avoided copy-pasting that said "bake at page 10, post in old thread"???

>>2799794
They're included in Octopart. Octopart is an aggregator for the big vendors like Digi-Key and Mouser, and a lot of smaller vendors as well. They also generally have a better parametric search function, allowing you to set a minimum value for the maximum input voltage, for example. Though can get a bit strange when different vendors have different data formats.

The reason I included LCSC separately is because Octopart doesn't scrape all the unique parts on LCSC, it only shows the western parts that LCSC shares with the other vendors. LCSC has a lot of interesting cromulent ICs that you can't get anywhere else, like linear high voltage LED drivers, TP4056s, along with chinky copies of western parts that go under different names, like the GD32F103. Their passives and jellybeans are also generally cheaper, though there is no free shipping threshold. They ship worldwide regardless of location, so if like me you're in a country where Farnell and RS are the only vendors available, you can see why it would be worth not paying $10 each for one of two available SMA connectors. Keep in mind the shipping thresholds though, more expensive part prices might be offset by free shipping.

In no way am I recommending using AliExpress or whatever as a replacement for proper vendors for anything but the most bog-standard parts. Or maybe surplus parts for a game console or laptop. I got out-of-spec TL072s once, and IR2148s that were dead on arrival. Stick to the proper vendors for things that matter.

30V is kinda high for electrochem, but sure. An instrumentation amplifier is the sort of thing you want for amplifying a weak signal without incurring offset, but such an amplifier can only provide so much current. Electrochemistry can easily get over 1A, which at 30V is 30W. That's a lot of power for a linear precision amplifier to dissipate. For that kind of power, what you'd end up doing is designing a DC-capable audio-style amplifier stage that runs off a split-rail supply (e.g. ±32V), and using the instrumentation amplifier (or similar op-amp circuit) in a feedback loop in order to make the output perfectly follow the input. It's also an option to go for a switching solution, though with a bipolar supply that can sink and source current I'd advise against it unless you really need high power.

Also the feedback loop of the existing equipment may interfere with this circuit. When it sets 0.1A through an electrochemical cell, it's constantly changing its voltage while measuring current in order to keep it at 0.1A. If it won't measure anything above 0.5A, then outputting 1A wouldn't work, even if your amplifier could take it. You may need to augment the measurement ability of the existing equipment, or even use your own circuit to set the voltage and current independently with a CC/CV amplifier combination.

I'd write down some specs. Maximum voltage, maximum current, accuracy of voltage, accuracy of current, that sort of thing.

you ground prep is going to determine how long it lasts but no countertop cut piece is going to be set into the ground deep enough to prevent rainwater and erosion underneath. you'd be better off getting a custom cut piece of stone that is thick. I imagine either is so expensive that building a crapshack of rock on top would be idiotic. Embrace dirt floors or start pouring cement a bag at a time.

Why is there a net over that cute lil' pond?

Here is a pic of current revision. I kicked the legs out 2 deg on left & right sides, (looks better to me) but even if I hadn't done that i would still have the same problem. My only idea now is to build the thing upside down.
anyone else have any ideas?

It should read EXPENSIVE project. Need to proofread

>>2799689
you're only showing the veneer, you have fucking zero info about how you're attaching one piece to another. if you're using blocks and screws just pre-drill and pre-sink screws in the tight spaces, you know, when the pieces are still just wood on your table and nothing is in your way. then when you put it together you can (*gasp*) use a fucking non-powered screwdriver even with your soi hands.

>>2799717
Well the whole this is 1x3 red oak ripped down to 2.25 " so that the legs which are laminated of 3 pieces so that its square 2.25x 2.25 inches. shelves are intended to be plywood with the edges hidden behind the arched pieces.
yes, screws and glue is how it will be built. pic is of end view, short of the last shelf.

>>2799739
You still haven't explained what the problem is

>>2799683
>go to screw it into the back plate
You mean the case?
If your problem is with the case, buy a better case.

>>2799700
the case is fine it's just that the GPU was built wrong
has about a 15 degree misalignment between the metal plate and the board

You can get a junkyard door and get it sprayed and installed by a bodyshop for a couple hundred dollars. This is usually the most economical option.
Picrel is an example of shitty bodywork. There was a dent below the belt molding, they masked the molding off, did the bodywork and painted it, and didn't seal the edge of the repair, so water eventually got in there and caused the bondo to peel off.
The mold growing above the molding indicates that the owner never washes the car, the mold holds the moisture in there also.

>>2799646
>door
just ignore it. or piece of tape over it.

>>2799659
>>2799662
thankyou so much. To the Rescue.

Does never washing cars can lead to molding and then to rust??

Major!!!

Or leaving it outside leads to molding and then moisture therefore my wrecking car..

>>2799691
it's even cheaper if you just find another white shitbox at the pick and pull, no need to paint.\

rust comes from road salt that isn't washed off, which can also be inside the panels between shit where a carwash doesn't reach. any exposed steel will rust eventually, that could be from paint rub from the trim or it could jsut be a middle america car. we used to just clean up the holes and put aluminum tape over them then hit it with a rattle can.

after you patch it up or get the door, sell that shit. it's going to be cancer as it continues to rust out.

>>2799571
I like to have my corded skilsaw set up at a work station somewhere for if I have to make a bunch of cuts or rip plywood but i will probably use my cordless 7 1/4 metabo 90% of the time as i'm moving around the jobsite making cuts on the go. They're both useful but the cordless gets a lot more use at this point.

>>2799718
>A corded drill
Anon, people haven't used corded drills on jobsites for decades. That's ridiculous. You're just a weekend warrior, why do you think your opinion is even relevant here?

>>2799829
all amerimutts do when your choice is between gutless 18v cordless drills or gutless 120v corded drills. but the choice doesn't matter when all their buildings are made of styrofoam lol. real builders only use corded becauses they're drilling concrete instead of american bullshit.

>>2799842
What lol

>>2799766
shouldn't you be using a fucking grinder or band saw instead of a fucking sawzall with carbide teeth?

zen would be something repetitive, quiet, detail oriented but simple, and safe
Working on a lathe is none of those
Try knitting or calligraphy

>>2799647
It is zen when you're watching Oddly Satisfying Ultimate Woodturning ASMR Compilation and don't have to deal with the sound or sawdust or otherwise engage with the activity.

I hate using my lathe nowadays. It used to be so much fun but now I obsess over little sanding marks and microscopic bits of torn grain or a less than satisfactory finish and I can hardly complete a project. I try doing new and challenging things but rarely do they turn out as I imagined and i throw them out.
OTOH, I saw some genuinely bad bowls in a small shop for local artists that people apparently liked but I have no idea how this hack was able to put a price on them in good conscience.

>>2799548
literally ZEN GARDENING
you know with the stones and raking patterns in sand and such. Wood turning is noisy and brutal.
Even clay pottery is more zen but still it places value in something materialistic meant to last and it gets imprinted with the creators touch which might hang around and prevent a complete passing from this existence.

Well you need to mount some legs to it for starters

i shineded a flash light on it and theres no electrical flowing out

>>2799444
It's blurry, you need to clear it up or the sun won't make it work.

Is it just me or has there been a drastic increase in the amount of retarded troll threads here lately?

>>2799534
Seems about normal, worst part is I keep replying.

The module in OPs pic is likely facing the wall for execution, judging by the tape over the diodes it was probably a drug mule.

>>2799433
Extremely good for cold climates. Very thick well insulating walls. Easily the best insulation/$ you can get.
>>2799434
It actually doesn't. The strawbales are compacted and covered in plaster. There is no oxygen for combustion. In germany, straw bale construction has passed the highest possible rating for fire resistance and is officially approved as building material. Your average stickframe and drywall mutthouse will burn a lot better.

Try removing it first.
Cut pipe remove escutcheon should be room for compression fitting. If you have to break out the drywall who cares you wont see it. Its a shithole anyway.
Thank me later

Is that a copper pipe coming out of the wall? That thing is covered in paint and crap but it could be soldered.
