Probably wrong board for this, but oh well.

So I made the mistake if buying an eBay micro SD cart, and of course as soon as I bought it, the listing it gone etc etc. Anyway, it's labeled as 64gb, it reads as 64gb, but try and write more than 2gb and it will come up with an error and everything corrupts, and refuses to read anything without a reformatting.

Is there anyway to tell the disk to display the correct capacity of the SD cart, or is this one destined to become landfill?

Its landfill
The onboard chip has been programmed to report 64gb to all inquiries while lacking the physical space. As soon as you run out of physical room the chipset shits itself.

Why the fuck did you despoil this nice woodworking bench with a bench grinder and metalworking vise? That stuff needs to go on a separate bench. Especially the bench grinder, since on top of covering everything in dust - which you just might not give a fuck about - it blocks the end vise.

break up that long loading board and use strong hinges to acordian the setup into a large ass tailgate. Have metal extentions that are going a couple inches beyond each of the sections to give it strength and stability when under load.
Sliding that onto/off of your truck will require you do move the snowmobile on/off of it at the same time. Unfolding and refolding that tail gate will be much easier.

I'm trying to build a moving sculpture, pic related. I want the eye (red LED preferably) to move in a lifelike, oscillating motion. A pre-built, battery powered set up is preferred, but at this point I'll take anything, because oscillating leds/ led sockets seem to not exist. Nothing too bright, like a police signal, either.

Anybody know where I could find this?

Judging from that gif the light seems to be stationary while the skull moves around.
Pedantics aside, if all you're looking for is a pulsating led, the circuitry wouldn't be that difficult. I would look into some adafruit stuff perhaps
You know, at this point I've considered just making the body oscillate around the light. Trying to do as little wiring as possible but if I have to then fine. I've also noticed that "oscillating" is a very poor search term for electronic components.

What I would try :

Get a glass eye pendant, put some EL wire or LED strip around it to make it glow, stick it on a balsa wood stick painted black (wires going to it too).

If you make the body move the glass will move slightly too. Otherwise you can have an electric motor drive the bottom end of the stick to make it oscillate.

How would I build a raised garden bed that looks EXACTLY like this? The outside is obvious, I'm just having trouble figuring out how exactly the soil is held inside and the inside structure that's holding everything together. I've reverse image searched the picture with no luck. I've never built one before, so I don't have any previous building experience to reference.

I dont understand your question.

The inside should just be a regular box with the fancy paneling on the outside.
But how is it black through the cracks? Is the inner structure just a frame with landscaping fabric attached and soil dumped into the fabric liner. It wouldn't look as nice with just a basic box with the framing on it if there wasn't the open spaces in the frame...
It's a box with some planks attached.

A jeweler's saw would also work, depending on availability in your area. Brownell's has them, as does Track of the Wolf. Not sure about blades for a luthiers bow saw, but there's a good selection of them for jeweler's saws, though you'd be interested in the coarsest.

First off, make some sketches and get those creative juices flowing through you because even some plaster and a good sense of decoration can make the coziest of cribs there has ever been.

Once there you can include essentials, like noise and heat insulation, air dehumidification (if it is that the basement happens to be damp like 93% of them) that can influence drastically how you manage your budget, and will directly affect how you get along with the place, say, the difference between crashing a few times...

I want to machine a copper block and create microfluidic channels in it. The main problem is that most machining is not used for this.

A simple question is how easy would is it to cut a copper block I buy that is 1/8" thick into smaller pieces that I can use to prototype? I am in a university so I'm assuming most machine shops should be able to handle this but is it really easy?

Does anyone know the best way to etch away copper to make channels? I want to make ~200um deep channels in copper that are also ~200um wide and spaced apart by ~20um.

Maybe paint it in anti electrical paint like used for electrolysis/electroplating except for the places you want the channel in and use it as the anode so it remvoo material from the exposed channels?
Afaik there are proprietary anisotropic etchants for copper, but they aren't going to beat ferric chloride in price. And I doubt you can achieve 20µm wall thickness with 200µm deep grooves.
If this were my problem, I'd consider using a 200µm thick copper stencil on top of the base copper. It might be worth checking what milling and laser engraving can do nowadays, too.

So, I wanted to make a forged folding knive. I forged the parts. And here comes the problem. I made the blade and the handle out of the same steel and tempered the blade. When I tryed to drill the axis holes I couldn't drill through the the handle. I used a HSS-G/Cobalt drill which is used for stainles steel. The strange thing is that when i drilled the axis hole through the blade it was no problem at all (I drilled the hole before hardening the blade with a standard iron drill). What have I done wrong?
11 replies and 2 images submitted. Click here to view.
1. If you managed to harden things properly you probably blunted your drill bit quite a lot drilling through it. Check to see if its blunt or chipped.

2. You said you hardened the blade not the handle, did you anneal the handle after forging? It might have work hardened.

2.5 If it did work harden and it's the same metal, you probably haven't hardened the blade properly, given that you drilled through the blade but not the handle.
What type of steel?
Some high carbon steels will work-harden (especially if they've got chromium and nickel) and become near impossible to drill through if it got a bit hot. The drill bit might also have become blunted and overheated as well, so make sure its kept sharp and cool, when I drill austenitic stainless steel which is notorious for work hardening I plunge, cool the bit in water, plunge, cool and repeat.

You can just normalise the handle section and that might help
I drilled the hole before hardening the blade (otherwise my heattreatment would be horrible). It is a new drill i have bought it yesterday since I wasn't able to drill throu the steel with an old one. But it works easy with standard hardwarestore iron.

Diy Ice machine. Been toying with the idea and gathering parts. I have THREE used ice machines and they suck my ass. They are too heavy to move, and only 1 woks but doesnt keep ice and is the size of my fucking car. I cant imagine what my electric bill would run if i lift it on. So onto a more manageable and redundant system. A chest fridge with side by side fridge ice makers installed. Theoretically 1 would fill it but take a lok of time and wear. In tslking with a repair guy i have lesrned a few small tricks to repair them but generally it is cheaper to toss the fuckers when they go. The cheapest ice maker "kit" i can find is about $90 pic related. I dug a little. Could maybe get the price down but not a lot.

On to the kiddie didler down the road. He buys pickup loads of shit appliances, repairs them, and sells them in his front yard. Hes all the time junking fridges.

If not i come acceoss used ice makers from time to time.

Ive looked into the tabletop ones but they dont pruduce fast and im not bailing water in the things. Hose or gtfo.

So, has anyone ever tried this?

I have 3 working ice makers and a small chest freezer to try it with.

The wiring might be a bitch. Some have like 5 wires. I'll get pics tomorrow of all the ones i have and the wires. Ive also heard no drilling in the sides as they house coper coils. Lid only.so ill have to be careful about water delivery and maker placement. Or build a drop bracket to mount them to the lid as im sure the 90 orientation will fuck shit up. If i ran these to switches i could easily colect a dozen of these things and flip switches as i need. If no hury just run a couple. If i have a big weekend and need a lot of ice we dim the lights and enguage warp.

I just dont see why i only found 1 shit one online. Why do more of us not have freeish ice machines? so what if one goes out, unplug it and throw it away?

These ice makers activate a 24v'ish relay connected to the cold water line. You'll need to tee into that.

I just want an ice maker that poops out 1.5" cubes or something that size. All these ice makers make small volume ice either to satisfy 'eco' water usage labels or because the motor to dislodge them are weak/cheaper.

Are you trying to produce ice commercially? Do you own a restaurant?

If so, and if I'm gathering this correctly, you're trying to produce ice with a bunch of fucking home icemakers to compare with a commercial ice machine.

Problem 1. A home ice maker doesn't get cold on its own. Putting it in a freezer would work, but still take a long time. A commercial ice machine gets colder than a freezer and is freezing layers of ice at a time to make a whole cube, 5-10 pounds worth, in sheet formation,...

What is the greatest horsepower electric motor I can get that will run on 110 volts AC at 15 amps? How about 20 amps?

I don't mean 'peak' HP (aka marketing HP), in which case I would use the '6 horsepower' motor in my vacuum cleaner and call it a day. I also don't mean theoretical HP. I mean legit horsepower that I can buy on the market today. I need a ~1750 RPM motor for a drill press I'm rebuilding and most of the crap I'm seeing when I google stuff is clearly lying about their horsepower output.

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...

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.
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

Just a fast one here.

I am looking for the best sources online (books/sites/videos) that teach the fundamentals of woodworking. I want to build some furniture pieces for my house within the next year or so, and would like to start learning now.

Hey I need to find a way to log or record everytime my laundry machine and dryer are used. Are there any ways to know exactly the date, time it was used and how long it was used for. Energy usage would also be a great plus !
How can I do this?

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.
Plugs? What are the sensors calls? Can I buy them online?
Any electricians here who can help?
