Sharpen Your Kitchen Knife on a Coffee Mug [Kitchen]

If you don’t have a knife sharpening kit and you’re in between taking knives down to the cutlery store to get sharpened, you can put a little bite back into your knife with a coffee mug.

Over at the site DIYLife they highlight a way to sharpen the edge of a knife using a coffee mug:

It’s true, the bottom of most ceramic coffee mugs have a flat, unglazed ring that is the perfect surface for giving that dull knife a quick sharpening. Just run the blade across the bottom of the mug at a 45-degree angle, working from the butt up near the knife’s handle to the tip. Slide the blade downward in one direction, keeping your fingers out of the way as you work.

We'd definitely stress that this isn't a perfect solution for continually sharpening your knives—if you want to sharpen your own knives the Spyderco Sharpmaker is an awesome at-home solution—but if you need to clean up the edge and buy yourself some more time before a proper sharpening, it'll do in a pinch.

Check out the full article at the link below for additional information and tips on sharpening other kitchen implements. If you have a knife sharpening tip or trick to share, let’s hear about it in the comments.

10. Stripped screw holes

I’ve moved a wall-mounted magnetic knife block between four different homes in the last three years, and now its screws just spin endlessly in place. This weekend, I’ll be gluing a golf tee inside the holes, then re-mounting that sucker on the kitchen wall. It’s a trick that will only work with screws that are, of course, at least close to a golf tee’s width, but it’s a handy one for those of us who put a bit too much push into our drills.

9. Booze-addled brains

A night out for drinks resulting in a rough morning is nobody’s fault but your own, though persuasive friends and the weekend can be a volatile combination. Get a good night’s sleep if you can, drink plenty of water, but while the night is still happening, try a booze-conscious diet. Not entirely easy to pull off, and it lends a less care-free attitude to the night, but it’s far less inconvenient than waking up feeling like a truck tire. The next morning, try a little ginseng, and consider taking up Lifehacker readers on their best hangover cures. Photo by cutglassdecanter.

8. Shattered light bulbs

If it was a completely clean break between glass and metal socket, you could simply kill a circuit breaker and twist out a light bulb with pliers. But how often does anything ever break clean? If you’ve got a bulb to pull out with glass still hanging, or you can’t get at your circuit box, try a potato cut in half to embed the sharp bulb and socket in, then simply turn it left to unscrew the bulb. Now you're ready to replace the bulb, and you've got a reason to have hash browns with your next breakfast—using the non-bulb-removing potato half, of course. (Original post)

7. Constantly loose glasses

The screw that holds your glasses tight against your head? It’s gone the way of seemingly everything on expensive and hard to fix items. When you finally get a miniature screwdriver and restore your snug fit, grab some clear nail polish and dab it over the top of the screws. It’s enough of a bond to keep the screws from coming loose again, but you could still get them out if you needed to. (Original post)

6. Splinter-stuffed hands

A simple tweezer session might free your hands of wood slivers, but sometimes they’re just too tiny, or too many, to try and remove with micro-surgery. If you’re fiending for a fix, try applying some glue to the afflicted skin, then peel it off to take the splinters with it. That’s one of the more powerful splinter fixes, but you might be able to get away with a banana peel or bath and pumice stone to pull out those ugly little remainders of your latest wood project.

5. Shiny but scratched gadget bezels

Gadgets with shiny chrome finishes look great out of the box. A few days of actual use, however, can give you that Why I Can’t Have Nice Things feeling. Smooth out your iPhone or any other gadget with a polished chrome-like finish by brushing the bezel evenly with a rough sponge. It’s a bug that becomes a feature on your newly-unique phone.

4. Failing hard drive

When your computer suddenly fails to boot up or starts randomly deciding it can’t find certain files, the first thing you’ll do is hope for, or confirm, a recent backup. If it looks like mechanical failure is the cause, and you need just a bit more data off that drive before it’s gone for good, try sticking it in the freezer until it’s good and cold, then let it reach room temperature again and give it another try. This passed-around tech geek tip works, as a last resort, because when worn-out mechanical parts fail to connect and align properly, contracting them with cold, then allowing them to expand again, can sometimes restore things to barely-working order just long enough to give you a little more time before the funeral.

3. Wet cellphones and other gadgets

If cellular companies were nice, they’d realize that running water, beverages, and rain are a part of everyday life. As it is, most cellphones these days have paper inside that change color when a little liquid completely voids your warranty. If your cellphone is on the fritz after an unexpected bath, we’ve recommended a bowl of rice, a bit of kitty litter, and, for certain phones in certain dire situations, even rubbing alcohol. They can't save your soaked gadget every single time, but when they do, you'll feel like celebrating—just keep the phone away from the table next time. (Original post)

2. Cables run amok

The cables may still work, but they make your workspace look and feel like an utter mess. We’ve often featured our IKEA-assisted de-tangling technique, but for those unable to locate one of those custom wire baskets, or facing a serious amount of cord length, reader Seandavid010 has illustrated the conversion of rain gutters into cord catchers, using cheap hardware bits and a little time with a cordless screwdriver or drill. Paint the gutters any color you’d like to match your walls or desk, and buy just the right amount to fit your needs.

1. Ugly, in-your-face web ads and annoyances

Pop-up ads, jittery Flash come-ons, auto-playing sound—they don't mean the whole web is broken, just a small, ugly part of it. Using Firefox and its strongest add-ons and settings, you can mostly eliminate the most unpleasant aspects of the web and regain some measure of control over what you see.

Pick the Right Screws and Nails for the Job at Hand [Tools]

If you’re a contractor, the charts and usage tips here will be old hat to you. For the rest of us, this chart helps make knowing which nail or screw to use less of a hit-or-miss prospect.

Unless you’re 12 and building a tree fort from stuff you scrounged from the back of your dad’s workshop, you’ve really got no excuse for using the any-nail-will-do philosophy. Nails and screws are constructed in a variety of thicknesses, strengths, lengths, and with varying threading and scoring to grip in the materials they were intended for.

The National Retail Hardware Association’s guide covers different nail and screw types, how to identify them, and more importantly how to use them to make your project safe and good looking.

Even if you’re already familiar with fastener types, their guide is packed with clever tips and tricks like how to use wood grain to conceal nail heads, and how to use a dowel to keep screws from splitting the end of a board. Check out the full guide at the link below for dozens of tips.

Turn a Five Gallon Bucket into a Rust Removal Tank [Weekend Project]

Rust removal is an enormous hassle, normally involving lots of elbow grease, steel wool, and sweat. Build your own electrolytic anti-rust tank out of a five gallon bucket instead and you’ll clobber your oxidized iron with science

This project relies on a few simple components—a five gallon bucket, some pieces of rebar or other narrow steel, a trickle battery charger, and some wire—and a washing soda/water solution to create an energized solution that's really tough on rust. The simple summary of how it works: you clip the negative charging lead to the item to be cleaned, the positive to the rebar, and then hit the juice and watch as the combination of electricity and washing-soda-laced water channel the rust right off your tool and towards the rebar anode.

Want to know the science behind how this Frankenstein cleaning tools works? Read through this Wikipedia entry about electrolysis. If, on the other hand, you want to dive right in and restore some rusty tools, check out the Instructables tutorial below for more information, appropriate warnings, and lots of pictures.

VehicleFixer Videos Detail DIY Car Repairs [Repair]

If you’re living without a seriously trustworthy mechanic, or you just like to bust out the wrench and fix your own wheels, VehicleFixer.com‘s descriptive videos are worth watching.

Many of the site's videos appear to come from old VHS instructional tapes, so the quality's a bit lacking by modern standards, and the cars are older models—though most of the techniques and parts are going to be the same as today's units. You're also treated to the cheapest synthesized soundtrack the tape makers could swing. But the videos on replacing brakes, changing oil, fixing belts and hoses, swapping out filters, and the like are slow, step-by-step, and explained in clear language, which is what really matters when you've got the hood open. You might have to do some clicking around, mostly to force more video and sidebar ads upon you, but VehicleFixer is probably still worth it if you want to learn how to get things done on your car. Free to watch, no sign-up required (though the site promises a share-centric members area coming soon).
