We have no time for this shit

Whoops, said 11 buttons and mentioned 10. It should probably have a start button too. I can answer any questions if they would help. Thanks in advance anons

That's the way to do it.
Parallel load the button states then "shift" them out in serial.
If you use 2 8bit shift registers hook 'em in series.

Use a second pin for the register clock.
Another pin for load/shift select

I2c, usart or spi can solve the problem, no need to bit bang a serial bus.
Are you going to use an rpi zero? Or the normal model? What kind of lcd are you thinking on?

There are a TON of different sizes of scroll saw. I'd suggest going to a local woodturners or woodworkers meet up and asking them, if you aren't sure. There's sure to be at least one pipemaker.

Use a jigsaw pussy

Why do you need a scroll saw? You really shouldn't be using a saw for anything but the general shape. Then you throw it on a lathe, whittle, and sand.

Secondly the frame sections are formed. the frame sections are made by bending and hammering sheet metal on a 0.500 square bar as a mandrel. Cut the sheet metal to a width of 2.563" refer to the template for lengths. First bend is .125" in an L shape, Clamp the sheet metal with the mandrel in the vise with .125 of sheet metal above the mandrel. hammer the sheet metal to form a 90 deg bend. Continue forming the sheet metal around the bar forming a square tube. Slide the formed tube off the mandrel. Cut the tube to the required lengths.

Third the frame is connected and a handle attached. The frame is jointed with thin steel bars bent and laminated together. cut 7- 2" length of .188 bar and 4 length of .125 bar. Bend the bars for the joints, referring to the template for the angle. each joint has 2 - .188 bars and 1 - .125 bars. drill through the sheet metal and bar bar, rivet using common nails. add a handle using the same process.

Lastly make the mounts for the saw blade. Cut a 1.0 section of .5 square bar. cut a slot .5 inches deep and wide enough to accept a hack saw blade. drill a hole intersecting the slot, corresponding to the hole on the hacksaw blade. drill a hole on the end of the bar and tap it to receive a bolt. mount this to the frame by drilling a hole into a joint and bolting through. the front mount is made the same way. a threaded rod is attached to the front mount, passed through a hole drilled in the frame and a wing nut screwed onto the end. two pins hold the blade in place

Excellent work anon.

>>942175
Looks pretty good.
You going to shape the handle for comfort?

>>942078
>inexpensive
Fucking where? They're always like $50 for a piece of plastic with two metal collars in it and a drill bit. I really want one still.

>>942180
Then get a plastic block, a couple metal collars, and a drill bit.
Drill *degree holes in the plastic,
glue the metal collars in
and youre done.

>>942180
Its really dumb that the vise grip is sold separately.

pulley in op gives no mechanical advantage

if you have a pulley that gives mechanical advantage then just swap the load with the ... other bit...

if they slip, you're going to the emergency room.

I'd get the jack stands myself, but if you think you can safely build footings, just make sure they're secure as fuck and handle the load.

>>942021
>spend something like $20 on wood to make some solid 8" tall wood footings
You're not going to be able to get enough wood to make stable cribbing for anywhere near $20.

Cribbing can be infinitely safer than using jackstands, but I'm 99% sure you don't know how to build up a proper crib.

Also, chinafreight those fuckers:

>>942028
that's why i'm asking; how do i make stable cribbing?

i was thinking a line of 2x6's standing on their end, maybe 4 or 5, with 2x8s sandwiched top and bottom. bolts through the 2x6's and screws down through the 2x8's into the 2x6's

Before anyone else says anything, I'm just talking about home usage. Of course more powerful PSUs exceeding 2000w can be purchased but they are usually for server environments where the available amperage coming from the wall outlet would be much higher. There have been a few "home use" PSUs 2000 watts and higher, but I have never found one that isn't either complete shit or doesn't require two separate plugs from two separate circuits in your house.

Pic related, external 2000 watt PSU, (legitimate) reviews say it is completely terrible and one review said the buyer had to plug the two inputs into separate rooms in his house to avoid tripping the breaker.

>>941976

I HIGHLY doubt a typical American house is wired for 15 amps.

In Australia a bog standard house connection is 75A @ 240Vrms = 18,000W

If you had less than 2kW then you wouldn't be able to run things like washing machines, driers, etc..

>>941976
if anything we'll see more people putting in dedicated circuits for their PCs since obviously most people run them longer than 3 hours and you don't want to fry anything
I don't see any one upping the power on these because they don't want to risk anything

>plug in lots of things
>switch on lots of things
>repeat till overload trip, profit.

be easier just flipping them manually tho. They are not generally designed to kil the unwary. Bonus points for finding a 'Test' button.

at the 100A fuse box just after the meter, you can reverse one phase with the neutral. this places 220V across plugs and lights, and should definitely pop the breakers without doing TOO MUCH damage to TVs and stereos.

At work I always found the best way to trip a breaker is to drive a screw into the Romex

This project has pricked my interests.

This is the detailing from a commercial one that was for sale.
Head looks like it was constructed the same as plush/teddy bear.

Just use a real bear?

Not sure what the issue is here, it's not illegal to hunt them...

Yeah, this is the "official" one, even tho it doesn't look anything like the one he uses(it's just a shitty cash grab, actually)
The original is 100 dollars cheaper, but it's really difficult to find
The original looks like it's made of foam, instead of the plushy one from your pic, but i'm scared i'm gonna fuck up the fur when i try to glue it on the foam(and btw, is insulation foam the best foam to carve this out of?)

>>941875
If you proprly primed the surface, it's either some specialty paint (not compatible with primer), large amounts of moisture, poor cleaning or old paint.

Those are "fish eyes" caused by impurities on the base. If it's automotive interior then it needs a major cleaning before any spraying due to numerous chemicals containing silicone, Armor-All to be specific. A good wax and grease remover and some elbow grease will get it off. DX-330 from PPG is my go to for cleaning interior panels. Remember to clean BEFORE you sand or else you risk embedding impurities into the substrate and you'll never get them out.

>>941882
>>941886

Ok, thanks. I guess I didn't clean or sand the material good enough beforehand. This rubberish stuff tends to build up on VW MK4 interior plastic and maybe I didn't get it all off.
Is there any way to fill most of these holes up?
Do I just try to apply more layers of paint until most them are filled or would this be futile?

>>941866
by designing them yourself or reverse engineering a product by taking it apart and measuring everything.

>>941866

did you try BING?

What kind of answer are you expecting?

>>941850
you can make your own custom springs with music wire

Make a spring cylinder that has adjustable volume.

>>941850
>Specifically, small springs.

In my experience, this is the hardest kind of thing to find. It's the perfect storm of "good fucking luck" factors: There's no standard, the equipment used to make them is specialized, and they're almost always made-to-order.

Honestly, the "buy some music wire and make your own" tends not to be that bad a suggestion. I keep a couple spools for this purpose, although I keep finding the stuff extremely useful for things here and there, too. The only other practical option is to poke around for spring kits and hope there's one in there that will work.

Noice. Reminds me of this guy I saw on YouTube a while back who would drive around the country finding log built homes. He'd buy some, or even be given them, take them down, then reassemble them back on his own property. Saving old homes with a lot of historical value is really badass. You should see if you can do something about it.

Pic: Moving a historical house down the river. House was built in the 1830s and is one of the earliest frame buildings in my county.

Thats cool. But I dont have land.. Otherwise I would give this a go.

Looks really cute. How're the temps on it?
