7 DIY Tech Skills to Teach Your Kids, Because Schools Won’t | Dramel Notes

Posted On // Leave a Comment

You want your kids to be successful; you want them to learn. But as far as you can see, the skills they need in the future aren’t being addressed by their school. Short of taking them out of the system and homeschooling, what can you do?

Well, you can make use of after school time and weekends, and use these family times to share knowledge that your kids will really need going forwards in life. We’re not just talking about using a computer here, either – rather, general DIY skills that cover all aspects of life, skills that they can use to prove their worth to employers, or even develop into a career of self-employment.

So, where should they start?

Wiring a Plug, Changing a Bulb

Many years ago, there was a big push to promote the teaching of basic tasks like this to girls. These days, it doesn’t matter if you’re the parent of boys or girls, wiring a plug, changing a fuse and changing lightbulbs are still not covered in school. Frankly, I don’t know why.

As is the case with all of the items in this list, it seems to be quietly implied by schools that parents should bear the responsibility of teaching these more practical to their children. And of course, this is fine – the problem is, parents rarely know which skills and specialties they should be exposing their young ones to. Schools offering guidance in this area are few and far between (if they exist at all). This seems bizarre, given the dangers of AC and DC electrical systems, and their importance to western civilization.

So, your first act as the parent of a child who has the necessary hand eye coordination should be to explain the basics of wiring a plug, changing a fuse, and buying and changing a lightbulb. These related tasks can teach a lot, and are a good foundation for the other skills listed here.

Teach Your Kids to Solder

Another vital skill that is remarkably simple to get to grips with (and with an achievable learning curve) is soldering. This is one of those skills that somehow gets overlooked by so many, and yet, when combined with the right knowledge and/or instructions, is so utterly vital; essentially, this is gluing in electronics.

Soldering might be used for anything from replacing parts on a PCB to creating a small radio transmitter. It is an incredibly useful DIY skill.

Our own guide to soldering is particularly instructive.

Fix Old Gear: You’ll Need a Multimeter

Why did that old radio stop working? More importantly, can it be fixed?

There’s only one way to find out the answer to both of these questions, and that is with a multimeter, a piece of electronic diagnostic hardware which can be used to measure voltage and current. Problems in circuits – whether wiring, printed circuit boards, or components – can quickly be traced, and with knowledge your children have picked up from rewiring a plug and soldering, the problem diagnosed and potentially repaired.

Multimeters are surprisingly cheap to buy, and typically come with a digital display, selector knob and three or more ports, where the removable probes are connected. Probes come in different shapes, from needles to tweezers and alligator kits. When buying a multimeter, ensure it comes with every option, and remember to instruct your children in safe usage.

Note: While DC/battery powered devices are typically safe to handle, never let children handle a live AC circuit. Continuity problems – checking if one wire is connected to another – should be diagnosed with the power off and disconnected.

Build a PC

I was 16 when I started taking apart computers (and putting them back together again!). Before this point, affordable home hardware were largely integrated systems, but it was the Commodore Amiga that taught me about expansion slots and swapping components out, and sent me on the road to building my own PCs.

With the deluge of notebooks, tablets, smartphones, hybrids and Apple iMac-like all-on-ones currently flooding the personal computer market, you could be forgiven for thinking that there is no need to be able to build your own PC. But most gamers would disagree, as would anyone wishing to save money while putting together a reasonably powerful device.

But looking into possible futures where huge unemployment might strike, or civilization might be on its knees, having some basic computer building knowledge could be a huge advantage, if only to demonstrate logical thinking and hand-eye coordination. Many of us will have a pile of old components gathering dust, and still functional equipment can usually be scavenged at your city dump or given away on the local FreeCycle messageboard – show your child how to put the components together into a working machine.

Woodwork & Metalwork Skills

These are increasingly rare in schools these days, despite the fact that society uses just as much wood and metal as it ever did (perhaps more, if we consider the importance of the three Rs: reduce, reuse and recycle).

Therefore, it is important for young people to know exactly how they can manipulate these materials, from hammers and nails to jigsaws and routers, with a bit of grinder, tin snips, metal shears, oxy-acetylene torches and more thrown in.

Check this video for a few tips on metalwork; and here’s our list of beginner woodworking skills you should know.

Install Any Operating System

You’ve already taught (or are planning to) your young ones how to build a PC. But what about installing an operating system? At the very least, they should be able to install a copy of Windows from scratch, but don’t overlook Linux as an alternative, as distros are easier to get hold of. Coaching your youngsters to install an OS on the Raspberry Pi is also extremely useful.

And don’t overlook the fact that operating systems can be installed from optical and hard media. Don’t leave them to struggle with CDs or DVDs if they don’t need to – impress the fact that a USB flash stick can be used.

Perhaps most importantly, let your child know that as well as keeping a spare operating system to hand on DVD, they should also keep recovery tools handy, just in case of a HDD failure or malware infection.

Learn Online with These Sites

As well as the skills listed above, you’ll find plenty of websites that can teach your offspring a whole host of DIY knowledge. While you’ll find a load of stuff on YouTube, you might want to check DIY.org, which also offers a gamified reward system full of activities for kids to demonstrate their new skills and work towards particular badges. They also offer paid “camps” to guide kids through particular tasks (an iOS 8.1+ device is required for participation in these), but the activities are available to all to see and be inspired from.

Of course, there’s many other DIY skills that could be taught to your offspring which they sadly won’t learn in school. Fixing an engine, plumbing, building a wall, and wiring a network cable are just a few of those that spring to mind. But what DIY skills would you teach your children? Tell us in the comments.

The Absolute Worst SSD Myth That You Shouldn’t Believe | Dramel Notes

Posted On // Leave a Comment

Solid State Drives (SSDs) are great, but there are still too many people who aren’t willing to pick them over more familiar Hard Disk Drives (HDDs). That’s because there are several myths surrounding SSDs, and one in particular that’s notorious: the myth that SSDs aren’t durable.

While it’s true that SSDs can handle only a finite number of writes, there are several other factors at play in deciding how far the life of an SSD will stretch. To understand SSDs better, the people at The Tech Report conducted a hardcore comparison of six SSDs of various brands. Each SSD responded differently to the tests, but all of them led to the same conclusion:

Yes, SSDs do die, but by the end, they all write several terabytes of data minimum. That’s more data than average consumers like you and I could realistically need.

The bottom line is that you’ll still need to be serious about backing up data on a SSD. But you can let go of the fear that SSDs aren’t durable and take advantage of the increased speed and performance they offer. You can even increase the lifespan of SSDs with tools and optimization tricks.

Don’t let the myths floating around stop you from making the transition, but do consider these five things before you buy an SSD.

What was the worst myth that you believed about SSDs? We’d love to hear about it in the comments!

12 Best Free and Open Source Android Apps | Dramel Notes

Posted On // Leave a Comment

Android is an open source operating system, but most of the apps and services aren’t available. What’s a free and open source software-loving person to do?

Well, it turns out there are a wide range of apps out there available to you. You won’t be able to do all the things you could with the Play Store, but you can still get a good amount of use out of your phone and use software that embraces material design.

Here are a dozen of the best open source Android apps to choose from, in no particular order. All are available in F-Droid, and most are also in the Play Store if you’re not concerned about using your device Google-free.

1) DuckDuckGo

Want to look for something online without handing over your interests to advertisers? Meet your Google replacement. DuckDuckGo is a search engine that cares about your privacy. The Android app doesn’t just look pretty, it lets you read articles inside its own internal browser, and the home page provides you with a look at current events happening across the web.

I enjoy this app so much more than I did the default Google Search app.

Download: DuckDuckGo for Android (F-Droid | Google Play)

2) AntennaPod

Listening to podcasts is a solid chunk of what I do with my phone, and fortunately, there’s a great open source option out there. AntennaPod isn’t quite as feature-rich as BeyondPod (my favorite Play Store option), but it has a modern look and gives me enough control to make sure feeds don’t auto-update over mobile data. That’s good enough for me.

Download: AntennaPod for Android (F-Droid | Google Play)

3) OsmAnd~

Part of buying a smartphone means you don’t have to lug around a dedicated GPS unit anymore. The thing is, most of the well-known options are all proprietary. Going open source means giving up access to Google Maps, Nokia Here, Sygic, and just about any other alternative you can think of.

Well, except for one. OsmAnd~ lets you download maps from OpenStreetMaps.org and save them to your device. You can save any number you want… from the entire world… for free. Searching for addresses can be a challenge, but if you pair the app with Address to GPS, then you should be good to go.

Download: OsmAnd~ for Android (F-Droid | Google Play)

4) Muzei

Muzei is one of the best live wallpapers around. The app blurs the background, only bringing the image into focus when you hold down on the screen. The settings let you adjust the amount of blur, and there is something satisfying about how the end result really highlights your app icons.

By default Muzei chooses a different painting for your wallpaper every day or so, but there are many other sources available, and you’re welcome to use your own photos.

Download: Muzei for Android (F-Droid | Google Play)

5) DashClock

DashClock is the solution to a dull home or lock screen. Use it to read email, check the weather, and keep track of alarms out of the box. When that is no longer enough, install any number of plug-ins to view content from third-party apps like Hangouts on the front of your locked phone.

Check your WiFi network, monitor battery life, and knock yourself out.

Download: DashClock for Android (F-Droid | Google Play)

6) Clip Stack

Copy. Paste. Cut. Paste. Copy. No, cut. Then paste. Paste again. Wait, no, I wanted something before that. Ugh, why did I cut? Where did I get that from?

Forget it. Open Clip Stack, browse through the history of clipboard items, and copy from there. Done.

Download: Clip Stack for Android (F-Droid | Google Play)

7) QKSMS

QKSMS is one of the many alternative SMS apps for folks who consider their default text messaging app too basic. Thing is, this one happens to be open source. The app was one of the early adopters of material design, and it’s highly theme-able.

There’s a night mode, plenty of customization options, and features to speed up your texting like QK reply — letting you respond without leaving the app you’re in.

Download: QKSMS for Android (F-Droid | Google Play)

8) Swiftnotes

Swiftnotes is a simplistic note-taking app like Google Keep without the online component. You give notes a name, body text, and a color, as if you were creating sticky notes. That’s it.

There are no tags or notifications or other forms of added complexity. If you just want to jot things down for later, this app is one to take note of.

Download: Swiftnotes for Android (F-Droid | Google Play)

9) Mirakel

Android has a ton of to-do list apps, but most aren’t open source. Fortunately, Mirakel is a capable and beautiful option. The app is feature-rich enough to provide filters and tags, set reminders, and rank each job’s priority.

There’s also a DashClock extension to put your to-dos on your lockscreen.

Download: Mirakel for Android (F-Droid | Google Play)

Download: Mirakel DashClock for Android (F-Droid | Google Play)

10) KISS Launcher

KISS Launcher takes all the distractions away from your home screen and replaces them with a single search bar that does everything. It launches apps. It dials numbers. It accesses settings. The memory requirements are low, and it does a good job of keeping it simple.

Download: KISS Launcher for Android (F-Droid | Google Play)

11) Material Audiobook Player

Material Audiobook Player provides a particularly pretty way to look at audiobooks on a modern Android device. It isn’t the most complete experience, but considering how visually unappealing many audiobook players are, this one feels like a breath of fresh air. Just make sure your collection of eBooks is DRM-free.

Download: Material Audiobook Player for Android (F-Droid | Google Play)

12) Amaze File Manager

Looking for a file manager? Amaze might just amaze you. It has the basics covered, and it comes with a few advanced features like samba support and root browsing. Also, it’s quite the looker.

Download: Amaze File Manager for Android (F-Droid | Google Play)

What Are Your Favorites?

Under the surface, Android remains an open source operating system. Proprietary software may clutter the ecosystem, but there are many good options out there for people looking for good free and open source apps.

Does proprietary code make you uncomfortable? What about being dependent on cloud services? Have you spent years waiting for a viable free and open source phone or tablet? Share your thoughts with us, and if one of your favorite apps is open source, give it a shout out!

13 Tips to Quickly Improve Your Photos | Dramel Notes

Posted On // Leave a Comment

It doesn’t matter whether you’re shooting with the latest and greatest DSLR or a three year old smartphone, what results is still a photograph. Good photos and bad photos aren’t determined by cameras but by photographers.

The difference between a bad photo and a good photo — or a good photo and a great photo — can be very slim. Subtle changes may be all that’s required to close the gap. With that in mind, here are 13 tips that will quickly improve your photos.

Post-Process Your Images

The single biggest thing you can do to improve the quality of your images is post-process them. You can use Photoshop, Lightroom, or any other app you like. There’s no need to make dramatic changes; simply adjusting the exposure, contrast, and color tone is enough to take an okay image and make it special.

The problem is that film photography had a look. Each individual film stock had certain characteristics and no two were the same. This is what Instagram filters try to replicate. Some films were contrasty while others emphasised green tones. Straight out of camera, film images have basically been edited.

Digital images, however, are designed to be neutral representations of the scene. Straight out of camera they are flat and lifeless; they have no character. Post processing them brings them to the same point that a film image is at.

Shoot Raw

You should always shoot RAW image files if you can — no matter what Bryan says. RAW files save a lot more data than JPGs so you have a lot more flexibility to edit your images after you shoot. This means that you’ve more chance of nailing the shot and creating a great image.

The only time you shouldn’t is when your camera doesn’t support it.

Instagram Doesn’t Count as Editing

Most of Instagram’s filters are great but they’ve become much too recognizable. Slapping an Instagram filter on top of your image might make it look kind of cool but it won’t make it a better photo. If you want to edit using a mobile app, try VSCO Cam instead.

Go Easy on the “X”

It doesn’t matter whether “X” is contrast, HDR, a vignette, or color toning, go easy with it.

Plenty of great images are ruined by photographers being too heavy handed while they edit. Unless there is a strong artistic reason to push an image hard in one direction it’s best to be subtle. As a rule of thumb, dial every effect you add to an image back from 100% to 70%.

Avoid Clichéd Photos

Selective color images—where one thing is a bright color and the rest of the picture is in black and white—aren’t cool, kids. They’re just one of many kinds of clichéd photos. This video from DigitalRevTV provides a great overview of 25 photo clichés. I don’t agree with all of them but for the most part they’re spot on. Avoid clichés like the plague.

Don’t Use a Massive Watermark

Nothing ruins a good image faster than an obnoxious watermark.

A small subtle logo in one corner is fine but your name in bold across the centre of the image not only stops people from stealing it, it stops people from looking at it. If you’re going to put your images online, you need to accept the risk that some people may share them or pass them off as their own.

Use the Rule of Thirds

The rule of thirds is a simple compositional rule that leads to stronger photos.

According to the rule of thirds, you should divide your image into both horizontal and vertical thirds. The intersection points of the thirds is where you should place your subject for the strongest image.

While it’s not true in all situations, for most things it’s a quick and easy way to guarantee a strong composition.

Watch the Edges of Your Frame

Real life doesn’t have borders but photos do. It’s easy to forget this when you’re photographing.

The border of an image is a compositional element. If something is placed too close to the edge it creates tension in the image. This can be a good thing or a bad thing.

In general, if someone is looking or moving in one direction, they should be placed on the opposite edge of the frame so they appear to have some photo to move into.

Don’t Chop Limbs Off

Similar to the point above, watch where the edges intersect with your subject.

You should avoid cropping a portrait so that it chops half way through a persons limbs; it looks strange. The best places to crop a portrait are at the subject’s neck, arm pits, waist, just above the knee, or not at all. Be careful that things like hands aren’t accidentally cut off even if you crop at one of those points.

Avoid Compression Effects

While humans have depth perception, cameras don’t. What we see as a 3D scene they render as a 2D image. This means that some things that appear to have no relation in real life have a relationship created by the compression to two dimensions. The classic example is a subject standing in front of a tree or lamppost. While you see the scene normally when you’re shooting, in the final image the tree appears to grow out of the model’s head!

To create stronger images look at what your subject is standing in front of and think how it will be translated to two dimensions. If you thing it might not look good, change up the shot.

There’s No Such Thing as Bad Light

There’s no such thing as bad light, but certain kinds of light suits some subjects better.

Harsh midday light is one of the hardest to use effectively. If you plan on shooting a glamorous portrait in it you’re going to have a very difficult time. It’s far easier to shoot portraits when the sun is lower in the sky.

On the other hand, if you want to shoot some high contrast cityscapes, the midday sun may be exactly what you want. Don’t try and force photographs in less than ideal circumstances, instead use the strengths of what you have to work with.

Shoot Portraits in the Shade or With Window Light

If you’re shooting portraits without artificial lights, the two most flattering places to do it are in the shade outdoors on an overcast day or inside by the light of a window. Both situations create wonderfully flat light that is easy to work with.

Don’t Use Flash

When you’re shooting in low light it can be tempting to use the pop up flash on your camera. Don’t do it!

Unless you have something like a bounce card to make it a softer light source, it won’t lead to good photos. It’s far better to increase your ISO or tighten your aperture.

What Tips Do You Have?

That’s 13 tips that I’ve found are quick ways to improve your photos. Learning each and every one of these has made every image I’ve taken since better.

This, however, is hardly a complete list! If you’ve any great tips to quickly improve the quality of your photos, please let me know in the comments.
