Is this pen your next 3D printer?


Scientists at Harvard have created an amazing new 3D pen that creates metallic objects with ease.

Similar to the recent 3Doodler pen in some concepts, this new pen goes above and beyond and was created for adult use, with various possibilities in mind.

This new pen could assist in making parts needed for medical devices. Earlier versions of 3D printers are held back in their ability to produce certain designs, because they have to be fixed to a frame for support. However, with this new printer pen, one can produce intricate objects that include bends, curves and loops.

With this capability, the sky is the limit when it comes to what this new printer can be used for. It may also end up playing a big part in the wearable industry, becoming the next big thing in how wearables are designed.

Pen turns silver to “ink”

This 3D printer pen works by using ink made of silver nanoparticles that harden when they are hit by a laser on the pen.

The particles are squeezed out of the bottom of the pen, while the laser is on, allowing an individual to create 3D objects right in the air.

What is really fascinating is how small the items are that the pen can create, because it is able to produce lines as thin as human hair strands.

Harvard’s Wyss Institute for Biologically Inspired Engineering team members discussed how they went about in creating this 3D printer pen. One of the biggest problems they had was figuring out the correct distance between the laser and the nozzle, in order for the pen to actually work. If the laser was too close to the nozzle, then the ink became solidified and clogged up the pen.

With all the things it can produce, this pen could well revolutionize the 3D printer market.

Next 30 day challenge: social media/news cleanse

For January 2015, I tried to declutter around the house for 15 minutes a day. We now have a couple rooms that are much cleaner, and I gave away a bunch of magazines.

For February 2015, my 30 day challenge was to go on daily 15 minute walks with my wife. That was nice.

Lately I’ve been spending more time than I’d like on social media and reading news sites. So for March 2015, I’m going to do a social media and news cleanse. I’ve done a social media cleanse several times before and it’s usually quite helpful for getting re-centered.

Here’s the steps that I’m taking:
– I’m using the StayFocusd Chrome extension to limit myself to 15 minutes a day of Google News, Twitter, Google+, Hacker News, Techmeme, Nuzzel, Reddit, and Imgur.
– On my R7000 home router I’m using the “block site” functionality for several of these sites. It looks like the R7000 can block HTTP sites, but not HTTPS.
– On my phone, I’m removing the new tab thumbnails for these sites. I’m also removing some social media apps from my home screen.

I figure that either I’ll get some good stuff done, read a lot of books, or die of boredom. I may (rarely) drop a link on social media, but if you see me just hanging out, please remind me to close my tab and move on. :)

My next project: AutoSEO

This was an April Fool’s joke.

I’ve been working really hard with some friends on a project to handle SEO automatically. Now we’re ready to take the wraps off it over at

One of the ideas that helped the World Wide Web succeed was that it separated presentation and content. You could write your text and decouple it from the problem of how the text looked. AutoSEO takes that to the next stage with search engines, so you don’t have to think about things like redirects.

How much would you pay to never have to worry about keyword density, H1 headers, or meta descriptions again? How about.. free? That’s right, AutoSEO is free for individual, students, self-hosted installs, and companies with fewer than 100 employees. AutoSEO is also built from the ground up to handle mobile browsers.

We’re starting with a limited set of invites to kick the tires on the system before opening things up for wider usage. Read more about the project over at!

This was an April Fool’s joke.

Meet AdSense’s next generation ads: Page-level ads

Today, we’re excited to introduce AdSense’s next generation ads. Page-level ads is a family of ad formats that offer a new and innovative way to help you earn money from your mobile content.

With Page-level ads, you place the same ad code once on each page that you want to show ads. They’re designed to show automatically at the right time and in the right format –  potentially increasing your earnings without interfering with your users’ mobile experience.

The benefits of Page-level ads include:

  • Optimized ads that show when they’re likely to perform well and provide a good user experience.
  • One-time set-up that only requires you to place the Page-level ad code once on each page you’d like the ads shown. 
  • Ability to adjust the settings in your account and to enable new ad formats without having to change the code on your site.
  • Additional ads on your site that don’t count towards your AdSense per page ad limit.

Watch the video below for a quick view of Page-level ads:

Currently, the Page-level ads family includes the anchor/overlay and vignette ad formats. More ad formats will be available soon.

Learn more about the Page-level ads in the AdSense Help Center. Get started with Page-level ads today and let us know what you think in the comments below.
