I need someone to explain this to me.

Weekly Roundup 9/10/11

In case you missed them, here are the most popular posts from the previous week.

Our most popular post was one of our Engine Hacks about a remote control airplane built by [Bruce Simpson] that has a pulse jet attached to it. It’s noisy and fast! Want to wake up the whole neighborhood, fly one of these around early in the morning.

Next up is this post about an unique window display that [Alex] built which draws onto the glass using a pair of stepper motors and a felt tipped pen. He is using processing and an arduino to control the motors. The end effect is that this device can draw gray scale images.

After that is another one of our Engine Hack posts where we show a lawn mower that has been converted to run on steam. This one is most definitely a hack and seems somewhat dangerous to boot.

This post shows off a working PIP-Boy 3000 created by [MyMagicPudding]. If you are a fan of Fallout, this is one to check out.

Finally, this post shows off a very large 3D printer that can print items as large as 15.8″ x 15.8″ x 12.7″. This is a custom built device and has a very nice writeup showing how it is put together.
