Dynamic Projection Mapping

Damn. They’re getting pretty good at this.

Terminator-Inspired 3d Printer

This is a pretty cool 3d printing demo.

It’s fun to extrapolate how fast 3d printing will get in the future. We’re getting closer, quite literally, to objects appearing out of thin air.

The $135 Million Oopsie

This is a pretty fascinating image.


It’s the NOAA-19 weather satellite that accidentally tipped over during manufacture in 2003. Repairs cost $135 million dollars. Can you imagine?

Mystery signal from a helicopter

This is one of the coolest/geekiest things I’ve ever seen.

After hearing digital interference in a YouTube video from a helicopter police chase, this hacker was able to figure out the helicopter’s flight path on Google Earth.

Here’s how she did it. Total badass.

Read the rest of her blog for some fun hacking adventures. This particular passage had me particularly entertained. While she was waiting to get some takeout food, the server handed her one of those papers that vibrates when your table is ready.

For this kind of situations I often carry my RTL2832U-based television receiver dongle with me (the so-called rtl-sdr). Luckily this was one of those days! I couldn’t help but tune in to 450.2500 MHz and see what’s going on there.

Amazing Invisibility Cloak Video

This looks like something straight out of a science fiction movie.

The full explanation is here. It has something to do with super-heating the carbon coils so they bend light. It’s pretty damn cool. This nano-stuff is finally giving us the cool science fiction future we’ve been imagining for centuries.

Five Hundred and Seven Mechanical Movements

This book, written in 1896, is a fascinating example of human ingenuity and cleverness. We don’t normally associate technical innovation with the 1800s, but don’t forget that’s when machines and automation in factories really started to take off.

Inspired by the book, Matt Keveney created a companion site, where he is animating some of the examples.

Check out some of these examples and you’ll see why this is so cool.

How to Vine With No Hands

Whenever I see people using Vine with no hands, I assumed they were doing it with paperclips and sponges or something. But it turns out you can do it completely from the phone itself. Duh.

The basic idea is to use the iPhone’s built-in functionality for helping people with motor problems. In this case their deficit is our benefit. Nice!

First, go to Settings > General > Accessibility and turn “AssistiveTouch” on.

Then you’ll create a new gesture. Just tap and hold in the center of the screen until the time limit runs out. You’re probably figuring out where this is going.

Then save that gesture and call it whatever you want. I called mine “Vine” because I’m original.

Notice that when you turned on AssistiveTouch it added a little circle thingy to your phone? Well that’s how you activate the gesture you just made.

Tap the circle, choose “Favorites”, then tap “Vine”. Then it will add an extra blue circle to your screen. Tap that blue circle to start recording.

If you’re having trouble, here are some things I’ve noticed:

You can reposition that AssistiveTouch circle thingy by dragging it. Sometimes using it in Vine only works when it’s on the left middle side of the screen.

Sometimes your Custom Gesture of just tapping and holding in the middle of the screen doesn’t work. So try making a new gesture where you tap, hold, and slightly move your finger around in a circle.

Sometimes ending the Vine video is tricky. If you can’t tap the Next button in Vine, hit the home button and wait a few seconds, then relaunch the app. Your Vine should still be there.

So that’s how to Vine with no hands. Enjoy, and keep using Vine to record your stupid crap!

This website looks amazing: Apparently it can make a 3D model of your face based on photographs, then print it on action figures, legos, 3D sculptures, and more.

If anyone tries it let me know!

This actually looks pretty cool. (Nevermind that the playhouse is the same thing as the picnic table.)

This little piece of genius is from a 1970 issue of Popular Science (Page 76).
