Robot cares for grave stones while honoring the dead

This robot was built to care for the graves and honor the dead in the Jewish tradition. It is called “Stoney” and was developed by [Zvika Markfeld] based on a concept by [Itamar Shimshony] who is working toward an MFA degree. The image above shows it in action as part of an installation; to our knowledge it has not been used for actual grave sites. But the concept is not a joke; it’s something that makes the observers think.

The base of the robot is an iRobot Roomba on top of which is built a platform for a robot arm. The arm has easy access to two palettes, one holds small stones, and the other flowers. There is also a small box which holds a rag. It navigates around the grave, placing stones, flowers, and using the rag and a water dispenser to symbolically clean the headstone. All of this is controlled by an Arduino Mega board which controls another Arduino running the arm, as well as the microcontroller in the Roomba.

The details of the ritual, as well as the components of the robot are well explained in the clip after the break.

Send your Nexus 7 back… to tighten one screw?

It seems that some of the Nexus 7 models have an assembly issue that makes the bezel uneven with the screen. It’s just in one spot but your shiny new toy shouldn’t have this kind of problem. Of course it comes as no surprise that Google wants you to send it back for service. What is a surprise is that the fix involves tightening just one screw. Now we can’t stand for shipping something round trip when it comes to this low-skill fix. Luckily neither can [Baddspella]. He shows us just how easy it is to repair the Nexus 7 yourself.

The only tools you need are a guitar pick (or other thin plastic prying device) and a very small Phillips screwdriver. Starting at the top of the tablet he uses the plastic pick to pry off the back of the case. This exposes the screws which hold the bezel in place. Find the loose one, and give the screwdriver a turn. Now just snap the back cover in place and you’re done. We’ve embedded the video after the break for your convenience.

It’s super simple…. so don’t be afraid to crack that thing open.

Summer and Tailgating DIY Projects Roundup

If you live in the Southeastern United States as I do, you’ve probably been enjoying a summer of grilling out and going to the beach or lake. You’re also may be getting ready to enjoy football tailgating season, especially if you attend or live near a college town. Here’s a couple of DIY items that should be welcome at any outdoor event you choose to attend.

How to Make a Cornhole Board:

Although there are no LEDs or an Arduino on this one (we’d love to see your pimped boards in the comments), these instructions should work well for making your basic cornhole set. Of course you can always add some folding legs to it, but they fit together pretty well as is.  As for the paint, there are many ways to do this, but check out the pic after the break to see the laser-cut stencil that the Tiger Paw in the first picture was made from.  Thanks [Essam]!

PVC Ladder Toss Set:

These instructions should tell you all you need to make your own ladder toss (or whatever less-PC name you decide call it). As for the golf ball “bolas,” you’ll have to figure out how to put a hole in the middle of them. This technique (as seen in a links post earlier) should cover it, but best to be careful that you’re not plunging into a liquid-core ball. Eye protection is recommended.

LED Glow Cubes:

Although not a traditional tailgate item, these glowing solar LED cubes could serve as an alternative to the normal LED path lights. What’s in these instructions is how to simply take the parts source, a solar path light, apart and insert it into a translucent cube. We could see this made with several different colored LEDs and an Arduino for some other cool effects.  A logo of your favorite team could be added with a laser cutter or CNC router for tailgate use.
