Although it’s not a new concept, you can’t deny that it is awesome. The Keerbot is a wall drawing robot. By hanging on 2 known-length strings, the Keerbot uses stepper motors to shift from left and right, and move up and down by contracting and letting out string on either side. While moving a pen/marker/drawing aid makes lines of art.
In some of the demos I see the guys working on getting a spray paint fixture to work. That could be more interesting than just dragging a marker. Currently the guys are using vector art, and known CNC utils to generate g-code. Very similar to how one would do laser cutting/CNC/and 3D printing.
Check out a few more pics and video after the break. Also make sure to check out the full lineup of videos and details on keerbot.com.

Everyone usually agrees that home made gifts are usually more heart felt. So instead of buying a gift, Christian decided to make one for a friend. Not too far from a musical birthday card, the Birthday Box, will present a message to the receiver on an LCD screen, and sing the song happy birthday.
The Happy Birthday Box uses a piezo buzzer for a speaker generated by an Arduino. The text message is displayed on a standard 16×2 LCD screen, and powered by a battery pack. There is a small roller switch as well, I assume everything turns on / off when you open and close the box but it wasn’t specifically stated as the functionality.
Keep this project bookmarked, and add a few LEDs for that valentine of yours.
Check out a quick video after the break; Source code and more pictures on Christian’s blog.

Looking for something fun to do this Halloween? How about scaring the crap out of people everywhere. Alton Porter has a pretty good setup for this. It looks like adding a lightweight skull (either wire-frame or Styrofoam), some LED eyes, and some tattered cloth. Just make sure you don’t interfere with the blades, nobody wants you to crash your quad!
This would be amazingly cool with a swarm of small drones. Great idea.
