Just put it between a vice.

either what that guy said or freeze both components and see if it'll fit

>>989901
Try a large vice and use it to press the hub on, Use WD40 before you attempt to help it slip on easier.

Or you can take a square of plywood place it over the wheel, and with a rubber mallet bang on the plate which will do the same concept as the vice.

Third place a square peice of wood on the floor, place the tire on the board, Place hub on the tire, Place another board over the hub sandwiching it, Then drive over the plank with you car the weight of the car should be enough force to squeeze and press the hub in place.

Again use WD40 for all procedures

Our first stop is what I would call "the usual China copy". It is a dark-blue SMD chip copy, with no special features added.
It has a SMD chip and a regular USB plug. (Variations of SMD/DIP chips and USB plugs are common, so I didn't get them all)

Note #1: there is two colors of blue common: a dark navy blue and a blue-green color, but I didn't show the blue-green color.

Note #2: I include the store names if you want to go buy one, but I'm not intending to advertise for the stores. I didn't hunt for the lowest price, so you may find the same thing cheaper elsewhere if you look. I just took a pic of what example I found first.

The second pic shows a hardware variation: this model has two crystals (the silver oval things).
I think this has something to do with what USB chip they use, but I dunno for sure. Some uno copies have one, some have two and some appear to have none, tho they may have a SMD version that just looks smaller and different.

This model doesn't appear to have any special features.

Example #3 is the Sparkfun Redboard, on the right. A standard official Arduino Uno DIP is shown on the left (pic taken from Sparkfun's website).
The official Uno costs about $25, and Sparkfun decided to make a copy for about $5 less.
The Sparkfun copy is all SMD parts and uses a different USB chip, but doesn't have any special [functional] features.

op here the pic updated with the small selector arm circled

Are the gears fine?

not really they have good size teeth on them but the gears dont seem to have anything to do with the side selection, that little arm is what really engages everything

My other welds i did a while back.Just wondering if they are ok or if i am looking for something else

>>989389
that welder isn't great for starting arcs. the best machines strike first time every time and keep the stick lit even when you're using it wrong - but the actual welds produced are no better.

honestly your welds look normal. i'd say you're good to go for basic farm-welding tasks like making brackets, shrinking bearing races, and welding nuts onto rounded-off bolts.

>>989036
As long as they are not chewing on the structure of your house...

>>989036
Do you have a wood framed house? Or is it brick or steel?

If its wood framed then you're pretty fucked, you could wait for the house to collapse on you and then sue the shit out of your landlord though.

>>989044
This. OP make sure you are dead, then you can sue your landlord for killing your life and ask for hundreds of thousands in compensation.

Making a thermoelectric cooler with PID control using an Arduino Nano. Similar to the one in the pic.

Slowly getting all the parts together for this https://youtu.be/s3dBox-LB7I. A midi synth guitar. Only need to buy the three softpots but those are expensive as fuck.

>>989001
how i can get into arduinos?

>>988807
that's really cool.

did you ever compare weights prior and post decellularization?

>>988881
No but now that you mention it I wish I had. woulda been cool to see how much stuff comes out

>>988881
I can say that it felt a lot lighter when I picked it up though

check out 'Denha' channel on youtube. He makes marble machines.

Why not use a chain with 'hooks' attached to grab the balls? Like mini fork lift prongs.

my 1st ever attempt at soldering, modding a cable, and /diy/ in general.

its stereo rca to 3.5mm aux, made it because the 3M and longer versions all cost too much dosh. didn't know about shrink tubing or electrical tape at the time, but I was smart enough to separate all the connections to prevent shorts and lucked out with the L-R channels being correct so I still use it.

1st attempt at woodworking. It's a brass resizing die holder. I had to sand it for way longer than I should have because the hole tolerances were too tight on half of em and I burned it every pass I made with the router

>>984591
fuck me I'm not australian

>>990386
Yes.

I took one of the mega PC fans (the 1.5A) rated ones, stripped away everything but the rotor and stator, and 3D printed a 1 foot diameter set of quadcopter blades, epoxied them on, and slowly cranked the power.

At 12Vit was spinning kinda
at 20V it was wobbling
At 30V it started smoking
At 32V it took off, tipped over, shrapneled the blades, and started on fire.

In conclusion, I would not reccomend customizing computer fans.

What's with /diy/ lately? Next some idiot is going to ask of there are any cool hacks he can do with 4 inches of string.

Can you take a picture of what it looks like at the moment? Having some trouble understanding what is covered by what. Did you bust the phone up so bad the hole is covered or is the tray warped?

>>990293
I'd take a picture, but my phone is dead atm, as it is usually nowadays. The phone is so busted up that the hole is covered up, yeah.

>>990293
The tray is fine, it's just the hole by it that is messed up.

>>990172
masks are supposed to release pressure from the inside to the outside
others only filter the inputs with no regards of pressure differential
nothing will happen unless the mask you are taking about is a diving dress
why you want to do this anyway? the tanks of those marker/pistols are filled with co2. if you wanna off yourself it wont work

>>990180
No the HPA tanks are for compressed air. What if I blocked off the exhale valve on the mask and put a one way valve after the regulator? So that there'd be low pressure air, and it'd only be pumped into the mask when I inhaled? And im not trying to off myself, just looking for something to do with these spare parts.

>>990183
Or better yet I wont even block off the exhale. So when I breathe in the valve from my air source opens, and when I exhale the exhale valve opens and the other closes?

Copper is malleable, just bend it around the edge, the bigger problem you're going to have is corrosion

>>990105
This. Copper is gonna start going green on you and it will start transferring to stuff you put on it. It will leave marks on the bottom of coffee cups and such. It will get nasty fast. Don't prep food on it unless you don't mind it tasting funny. Wont make you sick though. You'll have to coat it with something. Also, have you priced out a shoot of cooper of that size?

>>990071
Why copper? It's expensive and soft and will corrode. Get a thin sheet of aluminum or even plastic, like 1/8 or 1/4 inch, that'll be cheaper and easier. Where can you even find a sheet of copper?

>>989959
oil based paint is best unless you can get your hands on some lead oxide based paint. anything else will give you cancer.

>>989959

I assume you're painting the entire drawer and not just the drawer fronts if you're concerned about contact with utensils. The best paint I've used, although expensive is called Reclaim. Its around $120 per gallon, but I only needed one gallon for the kitchen drawer fronts and cabinet doors i did. Its very forgiving if your prep and cleaning of the cabinets isnt perfect, especially on old grease covered wood. Its super thick and self levels pretty well so it doesnt show brush lines or roller marks, makes cabinets look brand new when its all done. But other than that I would just use a good bonding primer after scrubbing and sanding the drawers and finish with latex paint and call it a day.

I'm a carpenter by trade, not a painter...but this>>989964 guy is a fucking moron

>>989988
I just wanted some information about whether wall paint is safe for contact with utensils. I'll look into your product tho.

Is there anything on the label that would indicate it's safe for being near edible products?
