How can I make my own barbell weights at home?
I was thinking of using cement but I don't have a mixer or a respirator etc.
Well, cement would work. But a thing to consider with using cement is that it's a brittle material.
If you were to say, drop the weight, there's a good chance that it might crack in half.
Obviously you can mitigate that issue by building around a rebar frame and using various fibers or additives in the mix.
Also, you really don't need a cement mixer or a respirator.
It's obviously not that great to breathe in but do consider that you'll be working with wet cement for basically the entire duration of the procedure and if you're...

Yea and my home gym floor is stone so it'd be cool to make rubber bumper plates like in my pic
Is there some kind of rubber substance I can like pour into a plate shaped mold and air dry to harden?
>>910454
Perhaps this might be a good way of doing it?
Pour a cement weight then coat it in Urethane?

So i have this cheap ass fountain. One of those "as seen on t.v" pieces of, some would say, shit.

>>910287
It has a mess of wires coming out the back but i think it is missing the pump.

To top it all off, this is the plug. Is it European or something...because I have never even seen an adapter for an end like this
I'm about to receive my first NFC stickers, do you guys use them? Let's post our usages
I'm going to use them with my phone and tasker to automate all sort of stuff, like turning my wifi off with a sticker on my door, silence my phone at work and other similar stuff.
Technically I could do anything that could be done with a phone and tasker so I'm looking for interesting creative usages, got anything?
Go shill your shit somewhere else.

the fuck is wrong with you

i dont know man i think it is stupid but i dont wanna hurt your feelings
I improved the performance of my miter saw by 83% with almost no investment of my money and a negligible amount of time.
Why haven't you?
Though I was fortunate in that Craftsman probably foresaw people doing this, and decided to make the recess fit 1/4" MDF exactly.
You just need to glue on a piece of scrap to "cradle" the kerf on both ends. This will greatly improve the durability of the insert. Doesn't need to be perfect. You just need to know that the kerf will not completely penetrate either end of the support piece.
Easy to batch out from one long strip of MDF. Use scraps for the kerf support.
Though I had to take off the fence to put it on, the kerf makes it really easy to square the fence super accurately.. Just stick stuff in it then butt it up against a square.
I have about a pound of BBs. My friend used them as weights to make a Christmas present seem heavier than it was, but it was ultimately a gag gift at my expense.
What is the most diabolical thing I can make with these BBs? I don't want to just throw them in his bed, I want to make something he has to keep and remember by it how much I love to hate him.
>>910085
>diabolical thing I can make with these BBs
pour them into his toilet, it will stay there forever
>>910086
I want to create something out of them, not just keep them singular.
get a good high-powered BB gun (CO2 powered). Get him drunk and get him to moon something. Fire a bunch into his ass cheeks when he's exposed.
You might get lucky with one that gets stuck under his ass skin, and will be with him for a while.
I bought a condenser microphone capsule
(if translated right). How do solder the wires to use it with a 3.5 audio jack

/k/ is making a religion. I can't be assed to come up with any ideas for religious clothing on my own. /fa/ is being a bunch of little bitches, so what would /diy/ suggest or submit as holy garments for the Kubist religion.
TL;DR Giant gun Kube gives reason for life through warfare. Gun is life. Life is strife.
Politics aside, what kind of garb shall we wear. Draw thread if necessary, but I'm open to whatever ya got.
>All religious people have distinct hats
Let's see what ya got
May your enemies die...

Hey /diy/,
I am trying to build the smallest ping pong launcher robot. I thought i could use co2 canisters but i am not sure how to use it properly. Is it feasible to use co2 canisters for My objective? What do i need to use for connections and selenoid valves? How can i connect the cartridge to the system since it requires to be opened by puncturing?
Thanks alot. Any keyword or another approach is very well welcomed.
You can try a bb gun magazine. It has a built in push valve. And an easy way of installing the co2 cartridge. You would only need a way to push on the valve to release the co2

You don't know what you're doing or enough to do this safely. You'll get hurt or hurt others by pursuing this project.
C02 cartridges have a vapor pressure of 850 psi at 70 degrees. You'll need a regulator and high pressure connections.
You don't know enough.

modify the chamber of a paintball gun?
I have this old freezer in my basement. It is a built in.
My plan is to take a chainsaw to it and cut it to peices to get it out.
Safety considerations besides PPE?
>>909715You may find that the simple sawzall if a far better tool for your task...
Just sayin...
>>909715
My only concern would be refrigerant gas leaking into and being confined in a small space, I don't know how you'd safely vent it out of the area.
>>909715
Built-in, hows? I've never dealt with one before.
Is it possible for a resistor to fail closed?
>>909526
anything is possible op
but improbable
if it fails due to heat then resistance will increase as it heats up then usually the film/wire catches fire and goes open circuit
if the failure mode is due to being dipped in hot solder for example then it could fail short circuit
>>909526
Dunno about a "real" short, but sometimes massive overvoltages can reduce the resistance several orders of magnitude.
Yep.
Source: twice in the last week (although to be fair it was the same fault on two identical boards).
Overheating seems to be a key element to it happening, green pcb had turned a nice caramel colour underneath.
What's a good size for PVC to make a homemade tricep dip equalizer such as this one?
None, that's retarded. Get a cheap mig and steel before you break your wrists.
>>909521
so basically make it out of metal instead or rip my wrists
>>909530
Yes
What types of places will sell small quantities of steel for diy projects?
I'm looking for about 4 feet of 8'' wide c channel steel. I've called a few small fab shops that don't have any and industrial supply places that will only sell me a 20' section
>>909456
I say try asking the closest trade school.
>>909456
Welcome to the world of people who like to do industrial crap for a hobby. I'm lucky enough to live near a metal yard that caters to anyone who walks in. You pay a bit of a premium for small pieces (in the form of cutting fees), but not too bad.
Look around and see if you can find any such place near you. If not, yeah, you're kind of stuck asking people/businesses who themselves would be using it.
discountsteel. They'll sell you any length you want. They will charge you a cut fee and if you're not local, shipping which won't be cheap.
I made these nukacola bottles. What do you think?
Nice, i would have gone with all curved coke bottles personally but thats just me.
Seriously dude, nice work, ive got a soft spot for fallout props so a nuka cola bottle is allways a winner in my book.
Plans for any more props?
>>909397
Very nice.
Just water and a light or did you add colouring?
So... you printed off labels, glued them to soda bottles, and shined light through them?
What tool is this?

I think im going to buy jbl e40 bt headphones, but i hate their look, giant labels, so i thought i could mod them somehow, ive got access to a small 3d printer, so maybe you have pics of modded headphones for design inspiration. Hope this is /diy/ and not /fa/, if so im sorry _.
>>909338
>jbl e40 bt
instead of doing that, pay money for something that is actually good instead of brand/marketing driven headphones.
>>909338
>I hate their look
Then why the fuck are you going to buy them? That's literally the only reason anyone would buy them in the first place.
>>909436
This guy is right. Get something decent for the same price.
