Fresh hacks every day
[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 … [Read more...]
A few weeks ago, we featured this water-based LED graffiti art installation that allows anyone to paint in light using only a bottle of water. When one of [Chris]' friends saw the video of this build, he immediately asked him how it worked. One thing led to another, and now [Chris] and a few other members at the BUILDS hackerspace at Boston University are building their own water LED … [Read more...]
What uses a fire extinguisher, a bike pump, and provides hours of probation, community service, and possibly jail time? If you said an automatic graffiti writer you're correct! [Olivier van Herpt] calls this little job the Time Writer. We call it defacing property... but tomato, tomahto. Details are a bit scarce, but you get a fine overview of the system from the video after the break. … [Read more...]
[Mikeasaurus] found a way to build his own refillable spraypaint canister. The donor vessel used here is a plastic soda bottle. It's a great choice since it is engineered to house a pressurized liquid and you can find them for free by intercepting a satisfied soda consumer before they reach the recycling bin. He repurposed the spray nozzle from a commercial spray paint can. By first releasing … [Read more...]
Here's an art exhibit that does its own painting. The Senseless Drawing Bot (translated) uses the back and forth motion of the wheeled based to get a double-pendulum arm swinging. At the end of the out-of-control appendage, a can of spray paint is let loose. We're kind of surprised by the results as they don't look like a machine made them. The video after the break gives a pretty good synopsis … [Read more...]
[mudlevel] built this rainbow graffiti producing robot for an art exhibit in San Diego. While there are no build details we can easily pick this apart from the pictures. Looks like the brains are an arduino, the drive is a power drill with the trigger removed, and a few other servos for firing the spray cans. The counter weighted arm for creating the rainbow was a pretty good idea too. Watching … [Read more...]
The txtBomber is a high-tech graffiti printer developed by [Felix Vorreiter]. Details are a bit scarce but the video clip after the break proves that this works quite well. [Felix] admits this is Arduino powered but we're going to have to guess at the rest of the setup from the pictures. He says there are built-in-pens so we'd bet there's a felt-tip type of thing going on and those look like seven … [Read more...]
