ID is about an inch.

Yup, that's crossthreaded.

NEways congrats on your purchase. Shopsmiths are more fun than a barrel full of monkeys.

Are you sure? I dont have a picture of it, but there is a second one that is exactly the same

Coconut oil: like 1 tsp for 15-20 mins, its got results like the strips but cheaper. I didn't have any bad effects from it other than swooshing for that long sucks.

Add Hydrogen Peroxide to your toothpaste. Not sure how safe it is, but it will work.

Ok well where the fuck to start
The ' effective resistance' of an led decreases as it heats up, a warm led draws more current which causes more heat. This is called thermal runaway and it kills leds. That's why you need a resistor.
The resistor value is determined by the difference in voltage between the source and the led (the voltage that the resistor will have to drop (voltages add up in a series circuit and are equivalent in a parallel circuit, google kirchoffs laws)) and the current the led needs (again, thanks kirchoff) then you use ohms law r=v/i (voltage in volts divided by current in amps gives resistance in ohms).

If you want to drive lots of leds you can put them in series, one after the other, but because of kirchoffs laws they all draw the same amount of current, you might want to be careful putting different colours in series because they might need different currents. You need one resistor for a series circuit.

You can put leds in parallel but each led will require a resistor to set the current.

Then the next step is to put sets of series leds in parallel.

So r=v/i where v is source voltage - led voltage ( add up led forwards voltage for leds in series)
Oh also for resistors you should find out the power, multiply the voltage over the resistor by the current through it, the resistor needs a power rating in watts higher than the value calculated. Usually resistors are 1/4 watt, high power leds that draw a lot of current might need beefy resistors maybe 1 watt or more.

Play with the wizard for some practice

As a Led enthusiast/fag I approve on this thread fully!

Smh...

I'm sure due to contaminants on your boot that the adhesion wouldn't be great, surely you can just peel it off gently? Or maybe heat a bit with your missus hair drier

maybe apply some oil and use a gradual rubbing and pulling motion

>>1085024
Cut the front of your boot off with a band saw.
Go to goodwill and find a similar boot
Cut the front off of new boot
hot glue the two together
enjoy your brand new boots


It may seem like a troll, but i have done this to alot of shoes and boots. I always get people asking me about them. I may quit my job and goto /biz/ and ask about starting a company around the idea. pls no steal.

They're typically ordered from china for a few cents a piece.

You submit your drawing, they print and cut on vinyl, laminate it between two sheets of acrylic, and cut it out for you.

>>1084847
You have to order a shit ton at a time. You can't just have one made and pay 5 cents.

try elecrow.

You just go and take the test. You can get more time for your OCD and a private room for your PTSD.

Okay, but I'm a stupid fuck who literally sold Runescape and Diablo 2 currency from Grade 8 through 12. I didn't graduate anything in grade 8 because of this but the shit-hole school wanted me gone cause I was a troublemaker and passed me under the table regardless.

I just want to throw money at this problem till it goes away, okay?

Register at a shady community college, bribe the tescher.

Bump

Check for a library maker space near you with a vinyl printer. For $10 you could print 100 of those.

Better off removing the tile.

>>1084348
You might need to thin the adhesive down with a suitable solvent and use something else to shoot it in. Giant syringe or a turkey baster with a 45* cut to the tip come to mind.

>>1084363
Why even post?

That would work, but what glue would you suggest? I can't even get the tile glue out of the tube with a caulking gun. Maybe slice it open?

>>1084234

I hate to say it, but probably the flathead screwdriver.

Not that it's all that great at any of the things you could potentially do with it.

hammer

6-10? Shit I tried teaching some highschoolers about 555 timers and it was almost magic to them. It takes some age and experience to develop an understanding for things electrical and electronic

>>1084174
Nigga I was doing that shit on my own when I was ten. It doesn't take a genius, just the right type of person. And yeah, most high schoolers in my experience are pretty apathetic about cool shit like that, but not all of them.

>>1084178
No you're totally right. There were a couple definitely interested promising kids.
Teaching is just tough, I had a new respect for teachers after that experience.

Wouldn't be efficient. You're probably better off with a battery or heating something up. The pump alone will eat most of the power, then the conversion from falling water back to electricity will have some losses too.

It could be a neat experiment but I wouldn't expect to be putting the power companies out of business with this method

1-3 gallons of water per person per day

>>1084149
To drink perhaps.

This would work but if not, use dry wall anchors. You can buy a box for a couple bucks at Wally World.

When I was a kid i got one of those bottle rocket kits for Christmas, it's just a bottle cap with a valve that releases at a certain pressure and has fins attached. Anyway i get the bicycle stand pump out of the garage and fire this thing off and its fucking garbage, goes a few feet in the air that's it.
But wouldn't you know it looking at this bicycle pump the nozzle looks like about the same size as a 2l bottle neck hole and wowee would you fucking believe it is a perfect snug fit.
Well a 2l bottle of coke will occasionally get up to around about 10 bar (not sure the psi sorry) before it tears itself a new arsehole and the smoke steam shit left after is pretty cool too, but the noise is unbelievable, yes police will be called and trust me they are not fucking happy when a half full bottle of iron bru nearly hits their car from a few streets away but they did bring it back so that was nice.

>>1084069
10bar is about the same as a bicycle tire (racing bike). At that pressure there is about 10-12 liters of air stuffed in that 2 litre bottle.

>>1084073
Makes sense because the gauge only went up to about 15 or something. Thinking about it now it might explain the debilitating fear I have of air tanks. Cant go near them, can't touch them can't be in the same room as them in case they pop. Is that ptsd or is it normal healthy fear?
