High tech tagging adds graffiti to poles

[Akira] looks to increase his urban canvas by tagging poles which some custom hardware. If you’re looking to add some art to a lamp post, height becomes a problem. That’s where this little guy comes in. The remote-controlled pole climber includes a marker that leaves a trail as the device climbs and descends.

The rig clamps around a pole, with omnidirectional bearings on three sides of the four-sided frame. That last side is occupied by a rubber wheel mounted at a bit of an angle. When the motor turns the angle of the wheel causes the jig to rotate around the pole and climb at the same time. To come back down the motor is simply reversed. Xbee modules are used to make a rudimentary wireless control with a button for up and another for down. It looks like the marker is also mounted on a servo but we didn’t see a way to control when it is actually touching the pole. Perhaps you can figure it out by studying the clip after the jump.

We’ve seen projects that climb poles before. Among our favorites is the one that takes your bicycle with it.

Ski pole persistence of vision

[Powder4u] wanted to make a persistence of vision display for his bicycle but with 50 cm of snow on the ground it’s hard to get out and ride right now. Instead he made this persistence of vision ski-pole accessory. We asked him to share some details and he obliged. It’s made using an Arduino compatible ATmega168, LEDs with resistors, and installed on some protoboard. The enclosure is a clear pencil case, which isn’t water tight but he’s tried to bolster that with some creative scotch tape placement. There’s no sensor to detect which direction the board is moving in so displaying alpha-numeric messages will have some issues, but as you can see he managed to display image data without issue.

We’re used to night skiing with floodlights along the slopes. This would be a fun little thing to have along with you on those dark lift rides.

Climbing bike storage thwarts thieves?

If you’ve got an expensive bike and don’t mind carrying around a whole bunch of extra weight in your courier bag you’ll like this concept. A design team built a pole-climbing bike rack in about 14 days. The video after the break shows the prototyping process as well as the finished “lock” in use. It’s a commercial for the company that employs the designers, but this is one kind of advert we don’t mind watching.

Square channel makes up the body of the device, with a set of Rollerblade wheels which grab a light pole and use three 12V gear motors for climbing. The controller is a wireless fob similar to those used for keyless entry on cars. In the video you can hear the cliché sound of a car alarm being set once the carrier reaches its finished height. Nice.
