[Dave's] drawbot writes his Facebook wall messages on a whiteboard. The setup is pretty simple, depending on a pair of stepper motors and common household goods. As you can see in the image, the stylus is a plain old dry-erase marker held by a big spring clip (the kind that holds a stack of papers [...]

[Dave] has an ASUS tablet PC with a little problem. The device is charged via the docking connector’s USB cable when plugged into a special wall transformer. The problem is that the wall unit tends to overheat, and is shut down by a thermister inside to avoid permanent damage. The word on the Internet is to [...]

The folks at The Quad Cities Collaboration and Hackerspace (QC Co-Lab) were trying to find something to build for their first big project, and had to look no further than the wall for inspiration. The north end of their facility is home to a huge 15×17 glass block wall that happens to face a well-traveled [...]

Instructables user [txoof] was unhappy with the fact that Olympus didn’t manufacture a wall power adapter for the E-510 camera and decided to do something about it. The resulting new power adapter is described in this article. What it amounts to is a fake battery pack made out of plywood. A 2.5mm DC power adapter [...]

The weekend is almost here and if you’re looking for an afternoon project consider building your own binary wall clock. [Emihackr97] built the one you see above using parts on hand, but even if you put in an order for everything, it won’t cost you much. He used a cardboard box as the housing for [...]

Instructables user [PenfoldPlant] is a big fan of indoor rock climbing, and while watching others make difficult climbs, he has often wondered if he could follow the same route up the wall. Unfortunately, aside from watching the other climbers and hoping to remember the path they have taken, he found there isn’t much you can [...]

So let’s say you have a submarine, or a nuclear containment chamber which has walls made of thick metal. Now let’s say you want to transmit power or data through this wall. Obviously you’re not going to want to drill a hole since this wall is either keeping seawater out, or potential contamination in, but [...]

Hack42, a hackerspace in Arnhem, Netherlands recently moved into some new digs, and they wanted an easy way to let their members know whether they were open or not. Fixed hours of operation typically do not fit this sort of organization, so that was out of the question. Instead, they built a switch into the [...]

[Andrew] sent us a video of his home made oscilloscope wall, which he uses to visualize different audio tracks he has created. The wall is made up of nine old broadcast monitors he wired together in his studio. At first it appears that the monitors are split into two sets of four, with the center [...]

[Alex] wrote in to let us know about this Kinect controlled LED wall that was whipped up at the Tetalab hackerspace in Toulouse, France. The wall, which was built earlier in the year, uses some MAX7313 LED intensity controlling shift registers. Each gets its own board and controls the intensity of sixteen different red LEDs. They’re [...]

No, it’s not an extra from Wall-E. “QB” is the latest telepresence robot from Silicon Valley firm Anybots. QB combines two-way videoconferencing with a Segway-style self-balancing platform. The idea is to provide mobility and more natural interaction than desktop-tethered conferencing can provide. The 35 pound robot’s battery runs for six to eight hours, and the [...]
