Here’s how to add the new Ender 3 V2 to Cura.

Cura has yet to update its preset for the newly released Creality Ender 3 V2. While you can leave many of the presets the same when you “Add a Printer” and choose the Ender 3, you do need to update some machine settings before you layout your design in Cura.

In this guide, we’ll show you how to easily update the Ender 3 preset in Cura to work for your Ender 3 V2.

1 – Add the “Ender 3” printer

• Open Cura
• Navigate to Ultimaker Cura > Preferences > Printers > Add.
• Select Add a non-networked printer.
• Scroll down to click Creality3D.
• Select the Ender 3.
• Click Add.
• Change “Printer name” to Creality Ender-3 V2.

Most of the settings from the Ender 3 carry over to the Ender 3 V2, so it makes the most sense to use that preset in Cura.

2 – Edit the placeholder machine settings

• Navigate to Ultimaker Cura > Preferences > Printers.
• Click Machine Settings to access the machine settings in Cura for your printer.

3 – Set the Ender 3 V2 Cura machine settings

You’ll need to change the X and Y axis of your “Printer Settings” to 220mm. But just to make sure, your settings should match these:

Cura’s built-in print settings will certainly work for the Ender 3 V2, but there are better settings that can allow you to print faster, for example, or use less filament. Here are the recommended settings that you should change for you change in your Cura print settings for the Ender 3 V2.

Download the Ender 3 V2 Cura profile

You can find the full profile mirrored on our GitHub repo. Download those profiles and import them in Preferences > Profiles.

Navigate to Print Settings

In the top right of your Cura window, you’ll find the print settings. You’ll see the print profile displayed—something like “Standard Quality.”
1. Click on the print settings to expand.
2. Click Custom > to access the full print settings list.

Recommended print settings changes

For everything else, you should use the preset print settings for the Ender 3.

Here’s Why Your iPhone Gets Hot While Charging (And What To Do About It)

You’ve plugged your iPhone in. You feel the familiar buzz to alert you the charging has commenced. You try to go about your day, but the phone heats up in your hand. You wonder, what could be the problem?

When someone plugs an iPhone into an electrical socket, a few things happen. The wire sends a signal from the power source through the wire, telling the phone it is being charged; if the phone accepts the charge, the phone starts charging.

If the phone does not accept the charge, it won’t respond to the charge and it will remain either dead or not charging. So, if you’ve plugged in your phone and you’ve noticed it is overheating, is there anything you can do to change that?

Yes, there is.

1 – Why is My iPhone Overheating?

Have you ever seen a temperature warning pop up on a phone screen?

The icon shows a hot thermometer and reads, “Temperature, iPhone needs to cool down before you can use it”? This symbol indicates the software inside the phone reached too warm of a temperature to function safely. This happens for a few reasons.

• You left your phone in a hot area, perhaps a car in the middle of summer. The sun warmed up the iPhone and heated up the software, which could affect the phone’s hardwiring in the long term.
• You use your phone in too hot of temperatures. Maybe you’re trying to play Pokemon Go, texting a friend, and sending an email. If you scroll back and forth between all of these apps, the iPhone will try its best to respond to your needs, but if you do this in direct sunlight, the phone might quit working.
• Running a lot of apps in general, especially when they require a lot of phone battery, can drain the battery and overheat the system.
• A bad battery or a malfunctioning iPhone could have its wires crossed, causing the phone to overheat at inopportune moments.

2 – Why is My iPhone Overheating While Charging

Now that we know some root reasons that cause iPhones to overheat, let’s take a look at some reasons an iPhone could overheat while charging.

If you plug your iPhone into the power source and notice its temperature’s continual rise, the device could be overheating for multiple reasons.

A bad charger

This is a common reason that iPhones overheat. If a charger does not work properly, it could send the wrong signals to your iPhone, tricking the hardware and causing the phone to overheat.

To avoid this issue, make sure the charger is intact and the port is free of dirt and dust. If the cord appears twisted or tangled, unplug it, untangle it, and try to reinsert the plug into the phone. If that doesn’t fix the issue, try to plug the cord into a different outlet. If the phone continues to overheat after all of these fixes, it is time to get a new charging cord.

Internal issues

This problem occurs when either the iPhone battery or the software inside the iPhone is compromised. To check what is wrong with the phone, you will need to seek out a specialist who can assess the inside of the device.

Apple stores or Apple support can point you in the right direction. Sometimes iPhone batteries go bad, and you need to replace them with the help of a technician.

Temperature is a hazard

When an iPhone is in the presence of extreme heat, it issues a temperature warning to its users. This occurs whether or not a phone is charging, but if a phone charges in a hot room, the heat could make the phone overheat.

To circumnavigate this issue, make sure your outlets and your phone always charge in a cool, dimly lit space without much direct sunlight.

The phone needs an update

Sometimes iPhones overheat because they can’t keep up with internal hardware. This occurs when an older phone has not been updated for a while.

To make sure your iPhone stays updated, visit the updates bar in settings and regularly check for new updates.

Charging and using the phone too much

If you charge the phone too much, the charge won’t work properly. The system will get overloaded, and thus the iPhone will overheat. The same goes if you keep apps and programs open on your phone at all times.

This will cause the service to lag and the phone to overheat. To avoid this specific issue, make sure to charge your phone when it needs it and to close out all apps when you are done using them.

3 – How Can I Stop My iPhone from Overheating While Charging?

Above, we mentioned some reasons that cause an iPhone to overheat while charging. Sometimes you cannot get to the root of the overheating, but you want to stop the phone from warming up. Here are some trusted methods to use to stop your iPhone from overheating.

Before you do anything, make sure to unplug your iPhone if you notice it overheating while charging. Leaving it plugged in can cause damage to the internal hardware of the phone and the battery in the long run.

Reset your phone

A great way to stop a phone from overheating is by resetting all of its data. To reset your iPhone, visit the settings icon on the home screen, click general, scroll down to the reset button near the bottom of the list, and click reset all settings.

This will take a few moments, and the phone might shut off during this process. If it does, turn the phone back on and monitor the heat and the speed of the phone. If it continues to overheat, you can try any of these other methods.

Giving the phone a restart

Sometimes, you can fix an issue by turning the phone off and on again. A hard restart turns the phone off in the middle of the activity and forces it to close all of the apps and shut off.

Track apps causing issues

Some apps available in the app store do not mesh well with the hardware of an iPhone. This means you need to figure out which app does not agree and delete the app. If you know that one of the apps on your phone is causing an issue, but you don’t know which one, you can figure that out in settings.

Click on settings, click on the icon with a blue and white hand that says privacy, and then click on analytics. This will bring you to a screen that shows your analytics data. Click on that and find the app causing the phone to crash, restart, overheat, or all three. Delete the app and see if the overheating continues.

Restore your iPhone

Restoring your iPhone is a great way to stop your phone from overheating. To do this, you’ll need to plug your iPhone into a device that has your Apple ID information stored. A Macbook or a desktop works perfectly. Also, make sure you have your information stored in the cloud because restoring a phone will delete data from your iPhone.

• Open the finder app, the blue and white smiley face icon at the bottom of the computer.
• You need to push the volume buttons as well as the power buttons until the iPhone shuts off completely.
• Now hold the side button for a few moments, the high volume button with the side button, and the lower volume button with the power button for a few more moments.
• After you’ve completed all of those tasks, a pop-up will arise on your computer. It will ask you if you want to restore your device.
• Click Restore iPhone under iPhone Recovery Mode and wait until the restoration finalizes.
• After that process, give the iPhone a bit to recuperate and then try to charge it again.

Update apps and iPhone

If you find your iPhone overheating while charging, you can update the software and the apps.

If a phone has several old apps and older software, it could cause the device to overheat. You’ll need to see which apps need to be updated by visiting the app store.

Apple Store

If all else fails, you can always visit an Apple Store and speak with someone at the Genius Bar.

4 – How To Tell a Phone is Overheating While Charging

If you don’t notice your phone getting hot, but you think it might be overheating, there are some other methods to prove the software is heating up. These include,

• The software operates at a slower pace. You can’t access apps at a normal speed.
• If the phone does not charge at all or charges at a super slow pace.
• You try to take a picture, but the flash is unavailable.
• The screen doesn’t light up as much as usual or it is black.
• You get a temperature warning.

How to Change Your Game Boy Cartridge Battery When Your Games Won’t Save

Nothing’s more frustrating than playing your old copy of Pokemon Gold, Silver, Red, or Blue for Game Boy and discovering that your game didn’t save.

Why won’t my Game Boy game save?

Most Game Boy cartridges that allow games to be saved contain a small internal battery to store your save states. Over time, this battery degrades and needs replacement.

See, back when these games were developed, flash memory was still super expensive. As a result volatile memory, powered by a small battery, was often used instead. NES, SNES and N64 cartridges also used such batteries for storing saved games.

This guide will show you how to replace the battery in your Nintendo Gameboy cartridge in about 10 minutes.

Watch the video, or continue below

I made a video tutorial that will walk you through the process. Or, if you prefer, you can continue reading the text and photo-based version of this guide below!

1 – The Game Boy game replacement battery

For the replacement battery you’ll need a CR2025 battery with pre-soldered tabs. This is a direct replacement for your old battery.

2 – Open the Game Boy cartridge

Nintendo was serious about not letting people easily disassemble their hardware! To open your cartridge, you’ll need a 3.8mm security screwdriver. These are inexpensive and will let you access a wide variety of Nintendo games and systems.

Remove the single screw from the back of the cartridge and remove the circuit board from its plastic housing.

3 – Remove the old battery

The Game Boy game battery is soldered to the circuit board via two tabs. Heat up each tab and then use your solder sucker to remove the old solder.

If you haven’t used a solder sucker before, it’s easy — just press the plunger down, heat up the solder with your soldering iron, and then press the button on the solder sucker and the plunger will suck up the melted solder.

If you don’t have a solder sucker, you can also use a slightly less expensive desoldering wick — but I find these much harder to use.

Using soldering “helping hands” can help to hold the circuit board but aren’t necessary.

4 – Inspect the old battery

Mine was from 2003!

5 – Install the new battery

Tab orientation matters here — see the attached photo as reference. Simply solder your new battery in place using a bit of fresh solder.

6 – Reassemble the cartridge

Use your special screwdriver to reattach the screw.

7 – Catch them all!

You’re now ready to conquer your favorite video game, with breaks allowed — and another ten years of save states ahead of you.

8 – Ready to take it to the next level?

In the wake of Google’s announcement that it will start giving a ranking boost to full-SSL sites, many companies are converting their sites to be full-https. In wake of this, it’s useful to check whether the resources (scripts, images, etc.) on your page are being loaded over http or https in preparation for converting your site. While you could technically view the source of a file and use CMD-F (or CTRL-F) to search for http:// or https://, this is not a preferable solution since the page source is not the full rendered version of the file. For example, there may be CSS or JS files on the page which load non-secure images. Therefore, using the Chrome Developer Console is the best option.

1 – Navigate to the Network Tab

Open Chrome Developer Tools and open the Network tab.

2 – Enable the Scheme column

Right click any table heading (i.e. Name, Domain, Type, etc.) and check “Scheme”.

3 – Reload the page

Reload the page and you will now see a column for http/https. Keep in mind, any time you open the Network panel in Developer Tools, you will need to refresh the current page; the Network panel only displays files which are loaded while Chrome Developer Tools is open.

Who doesn’t have an extra sock or two that’s missing a pair – lost forever to the black hole in the dryer! Grab that extra sock and a pair of scissors, and you have yourself a DIY armband for running!

Seriously, you’re going to be amazed about how easy this DIY Running Armband is to make and how comfortable it is to wear. You might even wonder why you doled out money for a fancy running armband!

The Top Ten Best Running Accessories (2022)
For some active self-improvement during the summer of social distancing!

1 – Grab your sock and scissors

Pretty much any trouser or knee-high sock will do. But why not go with one that has a little color!

I wouldn’t recommend a wool sock, as it might feel scratchy. And make sure the sock hasn’t lost so much of its elasticity that it won’t stay on your upper arm while running.

2 – Cut sock just above the heel

When you cut the sock in half, you’re generally looking to have a top half that’s about twice the length of your phone.

3 – Turn inside out

Take the top half of your sock (which is now your armband), and turn it inside out.

4 – Put on arm

I prefer to put the hemmed side on the top of my arm, but it doesn’t matter which way.

5 – Place phone over armband

Place your phone on your arm and over your armband, so that it’s about halfway up the band.

6 – Roll up bottom of armband

Bring up the bottom of the armband over the phone, so that it holds the phone snuggly. And that’s it! You have the best darn DIY armband for running out there!

Now get running!

I thought I was going crazy because . kept showing up while I was typing in Sublime Text. I realized that my terrible MacBook keyboard wasn’t [fully] to blame—it turns out there’s a new(ish) feature in macOS that automatically adds a period when you double-tap the keyboard, carrying over functionality from iOS.

This guide will teach you how to prevent macOS from adding a dot, or period, when you press the space bar twice.

1 – Open System Preferences

In the menu bar, Navigate to  Apple Icon > System Preferences.

2 – Access Keyboard Settings

Select the Keyboard menu item to access Keyboard Settings and then select the Text tab.

3 – Disable the macOS double-space period

Uncheck Add period with double-space. Then, close System Preferences.

You’re all done!

Speaking of ways to optimize your workflow, did you know you can also minimize applications in macOS by double-clicking the menu bar? Check out our guide to see how it’s done.

Changing your WiFi password is an easy way to add a little more security to your wireless network or change the random default password to something you can remember.

If you want to update the WiFi password on your Arris router, connect a computer to it directly with an ethernet cable.

1 – Log into your Arris router

Open a browser window, and log in to your Arris router. Visit our guide on how to log into an Arris router for specific details on this process.

How to Log in to an Arris Router

You’ll need to find your network security key, if you don’t already have it.

2 – Locate Security Settings

Once you’ve logged into the web portal, look for security settings. You may need to scroll down or check the sidebar depending on the exact model of your router. The field we’re looking for is labeled “Pre-shared key”.

3 – Set your new WiFi password

Enter the new WiFi password in the “Pre-shared key” field. Making the password more complex will be safer than using a simple one. Consider using a few rules when creating a new password. For example:

1. Avoid using dictionary words.
2. Use numbers and special characters.
3. Use uppercase and lowercase letters.

Enter the password again if asked to confirm the new key.

4 – Save the new changes

Click Save once the new password has been entered. Once the changes have saved, restart your Arris device, and test the new WiFi password.
