My bf punched a hole in the bedroom door of our rental. We're moving out soon and want to repair it in a way that will leave it looking pretty good. It's a shitty apartment so very slight discoloration is okay and wont stand out- just want it to look good. It's made of a crappy, lightweight cardboard material.
>>950143 Only suckers buy tools new (unless you need it right now for something you will be doing today and you can't do it without it full stop). Chinese made tools at that. Get a set used for cheap on CL and maybe drop a little on rebuilding the batteries.
If I had a license and was legally allowed to distill at home and bought a kit like this, what would be the easiest and simplest way to keep the worm box cold? http://www.moonshinestill.com/shop/stills/the-little-red-stovetop-6-quart-copper-pot-still
Moonshining is illegal and I'd make my own hard liquor without state and/or federal approval
Why is the cooling pan copper? Realistically all that needs be copper is what the alcohol (vapour) touches. That said, making the pot copper is a good thing, just not strictly necessary.
To keep your pipe cold just use a steady supply of cold water. Since I don't see a drain in your tray, maybe use ice bath instead. That said, you won't get great yields with a pot still, and you should probably look into reflux stills, or at least pack your worm with copper scrap on the uphill part.

any mechanical engineers or electrical engineers on /diy/? getting out of the military soon and need to figure out what i want to do when i grow up. mechanical and electrical engineer seem like pretty neat choices since i have like trying to build things and i love learning how stuff works and plus they seem to have a pretty big variety of what they all encompass to hopefully make finding a job easier. anyone care to share their thoughts and experiences, whether youre still in school or have a job?
Hey /diy/, got a small project coming up that involves some 3D printed metal involved. Since it's a small sized print though the metal color will be mostly bronze while it is a silver metallic look I'm after. I wanted to spray paint it but since this is an item I would be in contact with a lot and rubbing from use I was concerned the spray paint could come off. How have your experiences with spray paint on projects gone? What do you find helps them last longer after constant use?
What are some cheaper PLC's that can handle higher direct output amps then this CLICK PLC? Pic related can handle .3 amps but the electromagnet I have in mind will run .33 amps. Would this work, or would I destroy the PLC? 24VDC.
PLCs! Finally a topic I can talk about... I was a project engineer/manager at my previous job and spent a ton of time on PLCs (technically PACs).
Just use a relay. They are super cheap. You can get small ones in whatever voltage you need. How fast do you intend on switching the device? Large SSRs are <$10 on Amazon and you can get various small relays from whatever electronics supplier you like.
Transistors are fine, but I think relays are better because the available formfactors lend to control panels better and they are widely recognized in industry. Always... Comment too long. Click here to view the full text.
An oldish, all-steel saw blade. Clearly made of a nice steel, judging by how a file has trouble shaping it, and how it leaves scratches in drill bits. But too bad, it's made for a wacky arbor size and even if it were 5/8" I would never put it in my table saw because it is outgunned by today's carbide saw blades obviously.
I had already ground the tips off the blade for easy handling before I took this pic.
Finished with the first cut. I was happy with how I didn't seem to overheat the metal at all, but now I suspect the teeth are hardened to a much greater extent than the body of the sawblade. Well, this would make sense, I guess, but disappointing.
I think I might want to heat treat the steel after I cut out the blanks now.
what would the best way to measure speed be using a speed sensor hooked up to some kind of microcontroller (ie, the arduino.) Most likely going to hook it up to one of my own avr boards that I made, but since it uses the same chip as the arduino it should be fine.
Pic related, basic diagram of what I'm imagining. Are there sensors that can tell you the relative speed at which they're traveling in miles or km per hour if they were attached to some sort of spinning axle, for example on a wheel?
Come on, nigga, try a little harder. This is basic stuff.
Stick optical encoder on shaft (can be literally just a piece of transparency paper and the optointerrupter from a mouse's scroll wheel). Measure time between pulses. Determine speed by multiplying frequency of pulses by circumference of wheel.
im working on a Pip Boy model and im adding finishing touches, it has a satin finish, and i need to make it look worn and dirty like in-game, all ive got are cotton balls, paint brushes/etc, and light grey and black paint. any tips?
So i came home to discover the tree service my neighborhood association hired had decided to cut down one of my trees.Idk why but now i have to look at my neighbors crappy house.Whats a good fast growing tree to plant?I live in Pennsylvania so it would have to tolerate a real winter season and frost cycle.
