Not a 'bad' idea. There's a company on amazon that makes a large venturi separator that goes ahead of the shopvac. Fits on a lid on that 55 gal rubbermaid posted earlier.

Will drop 99.5% of dirt or better, into the bottom. It's meant as a fine dust separator so you don't run through bags and filters, or are stuck with the smaller volume of the shopvac.

ALWAYS, in regular operation, have a renewable filter on the shopvac (my pref over paper disposable) AND a (third party amazon cheaper) bag, when doing dry. The filter protects the motor, the bag catches the dry dirt. For this particular project, add the venturi, then all the dirt dumps into the 55gal.

welp. last time I did a project like this. i went to the rock/soils yard and had the put the dirt in the back of my pick up adn hauled it myself. that way when at home on the project, i just backed up the truck to where i was putting the dirt and easily shoveled out what i need, where i need it
thats just one of the infinite things that pick up trucks are meant for. if you dont own a pick up truck or know how to use it for things like this, then you should probably just stay inside the kitchen making sandwichs and doing the dishes

It's a railing, and based on the spindles it looks like the sort of railing usually used on deck stairs but a barrier is a barrier.
>removal
If it's screwed in just unscrew it from the wall. If it's nailed in you can pry it off, using something like a thin board or other material between the trim and the pry bar to provide a point of leverage for the bar but better distributing the pressure from the bar across more of the trim, preventing marring/crushing damage.
Alternatively you could tie a rope/strap around one of the horizontal boards and jerk it (giggity) to incrementally pull the nails free from the wall, repeating the process at each corner.
Alternatively alternatively you could approach from the interior and hammer the boards off from the doorway; again to prevent possible damage to the trim don't just sledge the fucker off in one go but tap them loose incrementally.

All the ones I have worked with are substantially heavier than a 15 amp. Maybe he bought some cheap retail shit, or didn't consider the density/strength/weight, just the looks.

They will 'look' very similar internally. i wasn't talking about that, but if you are mostly concerned with looks, I'm sure the chinese have some second-rate non-UL outlets that look the same, that they'll sell you. Your call.

>>2791547
In the circumstance, that the 20 amp breaker is on a single-outlet convenience circuit, next to the main breaker panel, hung on a wall and run through metal conduit, how I would do it, it should be 'ok'. If there was an overload condition, the wire is so short, that wire heating will be secondary to the breaker tripping. Although it won't be current Code.

Haha, no just one of the two “garage” fuses. I did google it, learned about how even though 14ga is rated at 20 amp or whatever you have to fuse at 80%. Forced him to come back and swap the 20A fuses for 15. I paid him, because his job was to replace the old 15A fuses, which he did. He just thought he was doing me a solid by dropping in the 20A ones.

Yes, if only the outer diameter is the main tolerance concern. Not all tolerances are equally important.
I assume this is an extrusion plate.
If it’s a shower drain, then make it out of SS.

First, rough-cut the slots undersize with a drill or drill press.
Next, using the slots, you bolt the roughly cut oversize outer diameter to a piece of wood and attach to something that spins at relatively low speed and file down to the exact diameter you need.
It’s better to have the piece this inserts into to check. Beware different metals have different thermal expansion coefficients.
Then dremmel out the peaks in the slots, and use a file to finsh to final dimensions.

>>2792209
I'd just drill holes then connect them with a thin file, since the shape is pretty simple. But if you want to etch it for whatever reason:
Print the negative with a laserprinter, use a hot iron to transfer to the metal, then drop small amounts of HCl or FeCl3 on it

>>2792209
>3mm (11 gauge) piece of steel

That's going to be tough since the material is so thin, it will easily get bent or warped from manual operations.

What I would initially try is glue the sheet metal to a backing material like mdf board. Print out a 1:1 scale drawing of the thing and glue it on top. Cut out the external shape using a manual jig saw. Drill a series of holes along the slots and use the jig saw again to connect the holes and then use a dremel to grind the edges to the right shape.

It's important while cutting to make sure your saw blade cuts only on the down stroke so that it doesn't try to lift the metal sheet off the wood backing. Heat the metal up with a blow torch or similar when it's done to destroy the glue and separate it from the backing.

Or avoid all this shit and find a sign shop with a CNC router.

Allow me to clarify: I want to aggressively go to the limits of the law, to solve problems I have not yet come across, to spite all manufacturers, including those I've never heard of.

I want all the data on all the screwdrives, especially those used on consumer products, such as the ones in the image, which is used in Toyota electric car batteries iirc

>>2792395
Look up patents. There will/might be scale drawings in there.

Also there is no "law" to prevent you from owning any type of tool for these. If you want to really become all capable invent a self stopping milling bit capable of eating itself into any fastener head till it stalls to then be used to unthread the fastener and throw it away.

Some OLEDS as well as some LEDs have a phosphorescence to them which causes the light to persist, thus muting the the flicker effect exactly like a CRT does.
Non-phosphor LEDs can be switched at ridiculously high frequencies and can be used for high speed communication.

I'm dumb and don't quite understand that diagram, are the circles supposed to represent the DC jacks, meaning that the circle part is ground and the middle dot is the voltage input? That's about the only way it makes sense, but I've never seen that symbol in a wiring diagram (which could be my fault).

if that's it, then thanks, I think I have some diodes lying around, not sure if they are schottky or zener though, if that matters (they are red-ish in color and that's about all I know of them, but I have a multimeter if there's any way to test - if it matters which type it is).

Question, in your diagram, the output voltage will be only ever 5V or 12V if 12V is present, never anything else, right? and the current sucked by the fan will be distributed across the two inputs, meaning this is completely safe?

>Always consider passive cooling before going to fans
It's a commercial PSU and almost ten years old. I just want to pimp it up a bit with fan control because it's in a cramped microatx case and the metal case of the PSU emits some heat, just enough so the case now blows out hotter air.
Technically it can run fine passively since I'm only using it at max 20% the rated load and I don't think the old fan started up on it in the past five years. It wasn't even dusty.
a picopsu would be better heat-wise, but I'm on a budget and the external DC power supplies for that would make it as expensive as a higher tier full ATX PSU.

>>2792353
>>2792353
> circles are DC jacks
Yes. They can be any input source… which is the point. Uncontrolled backfeeding into a battery is a disaster.

> only 12 or 5 volts
Correct. Minus the diode voltage drop which will be .7 V or .3 V depending onthe diode. Unregulated power supplies (like from a wall wart) are usually slightly overvoltage. Fans dont care, you just need to be in the ballpark.

The current will be whatever the fan wants. Looking at that dinky little fan, it’s going to be sweet bugger all.

> reddish diode
That is a signal diode, like 1N914 or a 1N4148.
You probably want a black one, like a 1N4001, but the signal diode might work if the fan is around 200 mA.

>You probably want a black one
Oh yeah, I'm pretty sure I have those. No clue which type, I just asked the local electronic store to just give me a handful. And that was 10+ years ago.

>Minus the diode voltage drop which will be .7 V or .3 V depending onthe diode. Unregulated power supplies (like from a wall wart) are usually slightly overvoltage. Fans dont care, you just need to be in the ballpark.
it will affect the RPM a bit, but probably only so much that I can't push the fan to max rpm, which ain't a problem since I want them to run quiet.

>Looking at that dinky little fan, it’s going to be sweet bugger all.
>the signal diode might work if the fan is around 200 mA.
that was just the only pic I had on my computer, the actual fan is a 120mm case fan, says it uses 0.1A 1.2W. Should be fine.

One more question, if either of the voltages change (the one on the PSU is thermistor controlled, the other will be software controlled by the motherboard), will that affect anything? Like PSU is 5V (fan does not spin), mobo is 7V (enough to make the fan spin up), but the PSU ramps up and gives it say 9V. Does that mean the fan will now get 9V, or will the secondary inputs 7V take priority? Looking at the diagram I'd say that the fan will get whichever voltage is higher, but I haven't taken EE classes since elementary school.

>This circuit is not rated for critical life support or life sustaining systems
I do keep semi regular backups from the PC this thing powers, so it wouldn't be that critical (had to deal with a lot of data losses in the past). Anyway, I'm guessing the worst case scenario is that the PSU fan voltage controller burns out and the fan will just not spin at all.

>>2792389
> whichever voltage is higher
Yes, the higher voltage will take priority

You can add more diodes in series to drop the voltage more if it’s too fast. Or switch more of them in somehow. Like with a switch. You can take the 12 V all the way down to 6 V f you want with enough diodes.

I use similar fans at 6 V all the time with no start up issue. These aren’t shaded pole, AC motors that may have a lot of trouble starting up.

If you want to limit the current you can get some 2 W resistors for added safety.

The 1N4148 can only dissipate .5 W max, but as a general rule of thumb, if they get warm, switch them up with beefier black ones.
