Here are seven of my favorite DIY/maker tips published this year in my weekly newsletter, Gareth's Tips, Tools, and Shop Tales.
Etching Metal with a 9v Battery
Etching is easier than you think. Leah of See Jane Drill demonstrates how easy it is to etch a metal surface using little more than a 9v battery and wires, vinegar, salt, and Q-tips.
Finding the Thickness of a Wire
Emory Kimbrough was one of the winners of my Tips book drawing in December. I asked contestants for one great tip. Emory sent me ten. And then, a few days later, he sent me another five – all publication-worthy. I’m excited to share them. Look for more Emory tips in the coming months. Here’s the first one:
If you need to find the thickness of a wire but don’t have a micrometer or calipers, wrap the wire around a dowel many times in a tight helix leaving no gaps between the coils. Now, just measure the width of, say, thirty coils with an ordinary ruler and divide by thirty. The more coils you wind, the more accurate your measurement. And even if you do use top-quality digital calipers, it’s even more accurate if you use this wind-and-divide method than if you measure a single thickness.
Organize Cables in Dollar Store Pencil Cases
The column I’m currently working on for HackSpace magazine will cover workshop storage and organizing. As part of my research, I asked for relevant storage ideas on my Facebook page. My friend Jake Hildebrandt shared this idea. Read the rest
Know Yourself is a set of 60 cards to prompt you to examine your beliefs. Example card: “List five things that are important to you in your life. How much of your time do you give to each of these?” The back of each card offers advice to make sure you answer the questions in a useful way. You can use their cards on your own or with another person you feel close to. Be prepared to surprise yourself. These could be good prompts for people interested in keeping a journal or writing a memoir. Read the rest
Matt Haughey moved into a new home with a lot of deadbolts. Rather than carry around a jangling morning star of keys, he decided to re-key everything. It took less than a day.
I researched getting a locksmith to come out, but it would run hundreds of dollars in their time plus you can only re-key locks to a key made by the same manufacturer, and by my count we had at least three different brands of locks spread among all the doors. I could save money by bringing the locks to a locksmith’s store, replacing off brands with a single brand and re-installing myself, or I could teach myself how to rekey locks using a ~$100 set from amazon that takes a few hours of practice to master.
He replaced three of the locks so all could use the Kwikset Smart Key [Amazon] system, the hero of the piece -- about $100 all in. Read the rest
For years we’ve had silverfish darting around our guest bathroom floor. I bought some silverfish traps (little cardboard boxes with sticky goo to ensnare them) and they helped, but didn’t stop them. In 2017 I read that lavender oil is a good silverfish repellent. It’s only [amazon_link asins='B00PYS7R7M' template='PriceLink' store='boingboing' marketplace='US' link_id='45821b01-58c1-4b72-95e5-f9356cc91bce'] for a small bottle on Amazon, so I decided to give it a try. I wetted the end of a Q-Tip with the oil and ran it around the perimeter of the bathroom floor, adding a little extra to a seam between the floor and the wall. It smelled nice and did not see a single silverfish for two weeks. I finally saw one, reapplied lavender oil on the perimeter of the floor, and it keep the little bastards aways for an even longer time. Now I hardly ever see them, and treat the floor every few months.

Hopefully you won't find yourself in a situation where you'll have to see if the "wipe away the flame" technique demonstrated here really works.

But Twitter also keeps track of IP address, device type, device ID and browser type and version. Technically, it will be able to use all those factors to link your activity to your account. Facebook goes further and even tracks your activity across other websites when you’re not logged in to your account.
It's very difficult to change someone's mind on a political issue. Facts rarely work, because the person you are arguing with has likely already been told the facts and has already formed reasons to dismiss the facts. But there are two science-back ways to argue, according to this Vox article by Brian Resnick, that will give you a better change of nudging someone, ever-so-slightly, in the direction you wish them to go.
Strategy 1: "If the argument you find convincing doesn’t resonate with someone else, find out what does."
Here’s an example. If you’re trying to convince a conservative of the merits of kneeling for the national anthem in protest, emphasize the traditional values around political and religious freedom. Willer suggests, “arguing that the founding fathers were deeply concerned with protecting our rights to social protest.”
Strategy 2: "Listen. Your ideological opponents want to feel like they’ve been heard."

In 2016, the journal Science published a remarkable bit of insight: It's possible to reduce prejudice, and sway opinions on anti-transgender legislation, with one 10-minute conversation. What's more, the researchers found that the change of heart can last at least three months and is resistant to anti-transgender attack ads.
It worked because the canvassers in the study did a simple thing: they listened... In talking about their own lives, the voters engage in what psychologists call "active processing." The idea is that people learn lessons more durably when they come to the conclusion themselves, not when someone "bitch-slaps you with a statistic," says Fleischer.
Hint: Don't dig around in there with a cotton swab.

How to survive solitary confinement
I like to read things like this, keep it in my pocket, so I worry less about what if it happens.
The recommendation is more or less -- you'll go crazy anyway, so go crazy with intention, to protect your brain.
The human brain does very badly in social isolation - we're not built for it, and people start hallucinating and dissociating very quickly when it's complete. It's actual torture, but people don't expect it to be because it sounds so low-key.
So the people in this article - both people who've survived solitary, and psychologists - suggest using a lot of visualisation. Imagine yourself in a much bigger space than you are, get to know it. Have a "workspace" where you train, maybe practice a sport in your mind. Every day, regularly, like you were outside and had a proper life. Imagine meeting a friend and having conversations with them.
Part of what makes you go crazy in isolation is the lack of external cues and structures, so it has to be structured visualisations, not just panicked uncontrolled daydreaming.
From someone who survived 7 years in almost total solitary confinement (again, this is torture, it is amazing he came out of it relatively okay):
"He he used to kill time for hours working out detailed visualizations of himself in a vivid alternate reality, where he could inhabit open spaces and converse with people.
It's frustrating to buy an article of clothing from a store, then get home and discover that the ink-filled inventory control tag is still attached. This happened to the Lock Picking Lawyer, but instead of wasting a lot of time returning to the store, he was able to safely remove the tag at home in a fraction of a second by holding a neodymium magnet against it.

Lifehacker's "Evil Week" tips aren't necessarily evil, or even unethical. They are all a bit sneaky, though, but could come in handy under the right circumstances. For example, if you have to make a phone call and don't want to get stuck talking to the person tell them your phone's battery is almost exhausted. Instead of buying new plants, snip cuttings from plants belonging to others. If you want to get a better deal on your credit card (like getting points or skipping the annual fee) call and say you want to cancel your card. The credit card company will usually give you a retention offer so you change your mind.

For those times when you are short a nickle, it's nice to know you have one stashed away.
The replies to the tweet are amusing, because more than a few people seem to think this is a joke and not a valuable life hack.

You can still buy an Ames Lettering Guide! They are cheap, too. I used one in college drafting classes and also when I drew comics for bOING bOING. I think I still have it around somewhere. In this video by our friends at Cartoonist Kayfabe, Jim Rugg uses an Ames Lettering Guide as part of his excellent comic book hand lettering guide. Jim is one of the best letterers around. Most cartoonists use computer fonts, so it's a treat to see Jim letter with an ink pen. Read the rest
In this beginner's guide to whetstone sharpening you'll learn how to give a cheap knife an edge so fine you can split atoms with it (or at least slice paper). The idea is to have different whetstones of varying grit (size of abrasive particles) and start from the coarse stones and move to finer ones. It's important to keep a fairly consistent angle as you draw the knife over the stones -- you can do this by matching the edge that the manufacturer put on the knife to begin with.
This is the knife used in the video, and these are the two whetstones. Read the rest

Project Farm is one of my favorite YouTube channels. They thoroughly test different products and methods for solving common problems that farmers, and just about everyone else, have. In this video, Project Farm tests a bunch of different brands of masking tape to see which one is the best at keeping paint from seeping under it. The bottom line: Frog Tape is the best in almost every circumstance.
