A small, battery-powered and very low-gear driven sticky rubber (silicon rubber) roller that clings to the wall and is squarely attached to the back of a picture or artwork frame. The device has an orientation sensor, either mercury or other sensitive level, that is periodically checked and if the sensor
indicates that the picture is crooked then the roller drive engages and moves the painting back to a level sensor reading. The low gearing and stickiness of the rubber help to keep the artwork from creeping back out of level.
The painting must be hung by a single point for this to work.
Conceptual scribble and rendering.

Monica Gellar would sell her chef's hat for this. |

I like it. This would be very useful in places that hang and re-hang pictures often, like art galleries (well, popular ones anyway). I think a mercury switch would be best - you can keep from having to use digital circuits, and use no battery at all when it's straight. |
|
| |
think of the time saved - top gallery gadget (+). |
|
| |
Nice. I consider myself a laid-back sort, most of the time, but crooked pictures drive me crazy. |
|
| |
Damn, I was hoping this would be something to keep me from slouching. But since crooked wall-hangings drive me insane, I'll give this a plus. |
|
| |
Evil Version: deliberately design a 10 degree skew into the widget, then give a picture in that frame to your Great Aunt Gertie. You know, the one who has OCD and is constantly dusting & such. |
|
| |
Poor Aunt Gertie, she'd never leave the house! |
|
| |
[krelnik] - if they were made using mercury, as suggested, some small, well placed magnets would do the trick. |
|
| |
+ I'll take a bunch. But I also want a haunted-house mode, whereby the pictures move around and mutter to themselves. |
|
| |
Good if your house suffers from subsidence in one corner, or is in an earthquake zone. |
|
| |
I think this one was preheated by Scott Adams in the Dilbert principle. It's one of the tests to see if someone is truly an engineer. |
|
| |
[bristoltz] - did you use sketchup for the illustration? |
|
| |
Scott Adams didn't provide a solution, though, he merely sugggested that a true engineer would be unable to resist solving the problem. |
|
| |
Yes, Sketchup. Delightful piece of software. I re-inked the line work, though, as Sketchup's line quality is horrid. |
|
| |
[BrauBeaton], yes, a flaw. I thought that hard felt pads could be used at the lower corners or little rubber balls that mimic the design of a ball-point. |
|
| |
Alternatively, an articulate tractor-tread or, like you wrote, a network of rollers. |
|
| |
[David] I've not read that but am not surprised. Crooked paintings are almost cliche. |
|
| |
I tried to read the print on the edge of the rubber thingy in the sketch. But even with Sharpen I could not make it out. Its too bad the cops and CIA don't let us have those really excellent sharpen tools like you see in the movies. |
|
| |
It says "bz 100 superformance" I think, or close to that, anyway. I knew it wouldn't be very readable but didn't think anyone would go to any lengths to try and read it. Next time I'll turn up the supersampling ;-) |
|
| |
The picture is straight. Your body is
crooked. |
|
| |
I'd love to bang into a wall full of these and watch them all adjust slightly differently. Or tip one way off and see if it causes a brief pendulum effect. Or walk past one in the middle of the night and hear the tiny whirr as it adjusts itself just slightly... |
|
| |
[edit] However please make it non-mercury if possible. Mercury too often gets disposed of improperly and contaminates things... |
|
| |
Wow! Biscuit for the artwork alone! Nice job brist! |
|
| |
Why would your picture ever BE crooked in the first place? My walls don't move much at all. Far less than a mercury switch would detect. I mean, this would be great for grass hut museums or for art galleries at sea, but for MOST pictures, two screws will ensure flawless picture hanging. |
|
| |
Two screws? I guess that's okay if you're hanging velvet art in a cheap motel. |
|
| |
Rip a 1x4 at 45 degrees into two equal pieces. Put one piece on the wall and insert one screw, but make sure the bevel is facing up and slopes down toward the wall. Then level and insert other screw. Affix other piece to picture frame in similar manner, but make sure the bevel is facing down and slopes away from the frame. Now hang the picture on the wall. Never ever needs to be releveled, and if you run a screw down from the top through both halves of the 1x4, it'll never get knocked off the wall. |
|
| |
Thank gawd you don't hang our art. |
|
| |
What if you regularly move your art like we do at our house? We hang our art as it is done in a typical gallery but we don't use the museum wire method as it looks ugly. |
|
| |
In any case, this is a halfbaked invention and defending the idea is out of scope ;-) |
|

This is indeed an outstanding presentation. Fascinating application of ultra low power device. I'm tempted to suggest power by phlogiston (phlogistological magnetic propulsion), but the quality of your work demands serious comment. Power by lithium cell would suffice for a couple of years, but that's quite pedestrian. The obvious candidate would be a small photoelectric cell (galleries are lighted, after all). Perhaps also an advanced version that ingests flying insects and slowly converts them into motive power for picture straightening. |
|
| |
I actually like [capeland]'s sea version. The boat will bounce back and forth, but the pictures will remain level. You'd need a little gyro and more power, but you could generate energy from the rocking motion itself. |
|
| |
She was truthing, it says "BZ100SUPERZOOM". |
|
| |
This is really cool. I find that the pictures that move the most are the little candid shots or 6x4 pictures with light frames. A tiny version (and cheap) would be perfect for this application. |
|
| |
Damn, I'm really pissed and greatly saddened that she won't be around anymore. It also depresses me that all too often a person isn't told how special they are until it's too late. |
|
| |
I was thinking of this the other day when looking at all my framed photos coming down the stairs. They all get knocked crooked all the time. |
|
| |
+ In the event that I happen to dust my pictures, (or one of my cats decides to dust them)- they always go crooked. |
