NASA scientists are experimenting with a process known as Additive Manufacturing. Essentially, this means that scientists want to be able to create custom metal parts on the go without the need for a full workshop setup. They also hope that the customization, in terms of ingredients, will allow them to adjust parts for various weather conditions on different planets, like Mars.

See the NASA 3D printer in action:

They have already 3D printed 11 metal parts that they sent aboard the NASA rover, Perserverance, which is scheduled to arrive on Mars in 2021. They’re hoping to test these parts as “secondary structures,” which will not ruin the whole mission should they not work. You can learn more about the specific parts and structures that they will be testing on Mars, by reading the full NASA article here.

Long term implications

NASA already has plans to establish a permanent human presence on or near the Moon by 2024. The hope is that, should NASA be able to use 3D printers to print…well…just about anything, then it makes the likelihood of launching a Phase 2 mission from the Moon to Mars a reality.

We’re going to have to wait and see, of course. But it’s definitely a cool time to be alive!

Head over to the 1Password website. From there you can take a virtual tour to find out just what is included with your free 30-day trial.

• Either click on Get Started if you’re on the homepage or Pricing from the top navigational bar.
• Select the kind of 1Password account you wish to try for free.
• Click on that account type.

This is the name that you want to call your account. In all likelihood, you’ll want your 1Password team account name to be the name of your organization, unless you’re getting multiple team accounts for different divisions.

If you’re setting up a family account then go with your last name, e.g. “The Smiths.”

• Write your account name.
• Write the email address that will manage the account.

Your email should be the email address for your company—one that most of the team has access to, for example—or the account for the person who will delegate the password sharing on 1Password.

1Password will send you a 6-digit code to verify the email on your account.

• Enter your 6-digit code.
• Click Next.

You should now be redirected to your new 1Password account. Where you can:

• Create custom groups
• Manage team/family members
• Import your passwords
• Create new passwords
• And more.

Be sure to download the 1Password apps across your devices and instruct your other members to do so as well.

When your free trial expires, you will not lose all of your saved passwords. You can still manage all your saved passwords on 1Password, but you will not be able to add new ones.

1Password allows you to download a file that you can export to a new password manager, should you decide to choose a different one.

Free trial extension

If you’re really nice…we mean really nice…then try emailing the folks at 1Password to see if they would extend your trial for another month or so. They likely believe strongly enough in their product to let you try it some more!

As of right now (October 2020), you’ll see two options for 1Password extensions.

1Password X

This is the beta version of the 1Password browser extension. It’s still safe and secure, but certain features may not have smoothed out completely or there may be an occasional bug. If you’d like to contribute to the future of 1Password, then hop aboard the beta adventure ship!

1Password extension

This is the official and full browser extension for Chrome. This one will not change and is recommended for those who are new to 1Password and password managers in general.

• Choose which 1Password for Chrome browser extension you want.

• Click on the desired 1Password extension.
• Click Add to Chrome.

When the security warning pops up, select Add extension.

We’re assuming you’ve already created a 1Password account before this, but if you haven’t then you should return to 1Password and create one.

Here you’ll need to write:

• The email you use for 1Password.
• Your Secret Key.

This is the key that 1Password gave you when you first created your account. It can be found on your 1Password Emergency Kit (see image below). – Your Master Password.

This is the password you created when you first set up 1Password. This is the one you use to activate 1Password while browsing and can also be found on your 1Password Emergency Kit.

Stay safe!

This project was created by Bryan Mayland. He’s worked on this project for years, perfecting this heat sensing project.

Now you can get in on the action. Bryan sells HeaterMeter kits on his website to help others who are interested in the same project. He’s saved us all a great deal of time by consolidating these resources together. More time for grilling, right?

First things first, you’re going to need a couple of tools. Even of you start off with the official Heater Meter kit, you’ll probably need a few extra items.

The kit doesn’t include:

• Raspberry Pi
• Wifi adapter (if you’re not using a Pi 3B or Pi Zero W)
• SD card
• 12V Power supply
• Pit probes
• 3D printed case

This is where things get hot! Unfortunately, the puns also get worse.

The pit probes need to be built to spec. If you’re not sure where to get started, check out this amazing pit probe tutorial by Dave Selinger. He does a great job walking you through the construction process from start to finish. The pit probes are crucial to the project. Definitely don’t skip over any details.

HeaterMeter will run on any Raspberry Pi. But not every Pi is the same, some have serious benefits that make all the difference in a project like this. If you can, aim for a newer model—these often perform better and some come with built-in wifi adapters which are really useful for this project.

To install the HeaterMeter software, visit the HeaterMeter downloads page and find the appropriate image for your Pi. The image needs to be flashed to the SD card with an imaging program like Etcher.

Once you have your components created, it’s time to gather them together! Your pit probes should be installed and connected to the HeaterMeter. There are thorough instructions available on the HeaterMeter wiki. I highly recommend this resource, especially if you’re using extra components like multiple pit probes or a damper.

Congratulations! Once everything is assembled, it’s time to fire up the grill.

Don’t worry about what’s going on across the yard, now you can check it out for yourself. This is your time to grill with mobility. Want to check on those steaks you put on a moment ago? Just take out your phone and load up HeaterMeter in the browser. Does it feel like the future yet? I think so.
