Waylan says, “This site is dedicated to showing demonstrative videos produced by our community. For many subjects seeing something done is the most effective way to learn, whether it’s peering over an expert’s shoulder while they explain how to program or watching while someone grinds beans and makes coffee. Please watch, learn and perhaps share your knowledge back.” Shown here is David Rawlson’s video covering the basics on how to maintain your car, including the tools you need. Link.
Something from the comments: Thanks to Shifzr for pointing us to this amazing drink serving robot from the 1980s. They actually sampled Hal, “completely operational and all my circuits are functioning perfectly.” How else can you reply but to say, “Open the pod bay doors and give me a vodka tonic!”

While going down the rabbit hole of exploring links, I found this very odd virtual video of a robot that serves drinks. Someone is getting ready to get their robo-drink on for Roboexotica, the worldwide gathering of drink serving robots. – Link to video page – Thanks Kate!
Gareth Branwyn, who authored the beambot article in Make issue 6, wrote up a cool article about Zach DeBord’s twin-engine solarroller. This thing is a beambot hotrod!
Zach on building BEAM Roller circuits: “I usually build engines in a batch for later use. In the image below, you can see that there are sockets on top of the engine circuits (made from IC socket pins). These are used to easily plug in the solar cells. The two leads (red and black) coming out of the back of the engines go to the motors. In this picture you can see the two types of engines that I make: one “classic” configuration with storage capacitors (the two engines on the left) and another config using Polyacene disk batteries in place of the caps (which deliver roughly .6 Farads of stored power). These are represented by the three engines on the right.” - Link

Daisung says, “I’ve uploaded some photos of my analogue phone + old Nokia phone. I’m currently overseas so I’ve had to leave it behind, but every time I’ve used it, I got great reactions out of people who were extremely curious. The handset works just like a regular phone by the way!” Link.

DIY street legal luge + awesome helmet = RAD
Back in the late seventies, I was a skateboarder. I would find the biggest hill I could and bomb down that thing as fast as I could. I didn’t do tricks or flips. I was a gravity junky. 10 years and some common sense later, I wasn’t skateboarding anymore but I saw this street luge on TV andthought it was awsome. The main drawback is that it was missing something that I cherished after a few scary accidents, mainly brakes. I put the idea aside for a possible future maybe project…
…until 3 years ago. I don’t remember if it came to me while on the can or in the shower but I was thinking to myself that if I built a street luge, not only should it have brakes, but it should be street legal to avoid any hassles from the law. Street luges are considered as skateboards here and a skateboard is illegal on public roads. But not bikes,hmmmmmmmm. – Link
Ok, simple DIY hacks have been around for a while, but Flickr is rolling out the red carpet on geotagging your photos.
If you just want to jump in and start geotagging, open the new ‘map’ tab in the organizr and go for it. It’s all drag and drop and easy to figure out. Since location information has its own privacy setting — so you can keep the location the photo was taken private, even when the photo is public — you’ll be asked to set a default privacy setting before beginning.

A few months ago, I wrote a post about some making a Rube Goldberg Contraption in the forest and we made a fun, but shaky, video. We resolved to do it again sometime. The Discovery Channel stepped in and motivated us to do just that and so with a TV crew on the way, Jesse, Brenda, and I reconvened and came up with some new sticks and stone elements for a new and improved forest machine.
The Discovery Channel guys were great and patient and helped reset the rock dominos and were awesome to work with. We had a total of 24 different events happen in this forest machine! Rube Goldberg contraptions never work on the first try, but we did finally get the whole thing to work after two solid days of work and 124 tries. We didn’t want to have an effect on the environment so we used hundreds of feet of twine and rope. (We did use some nails, but we only put them into branches that we found dead and on the ground. We also used two rusty pulleys that we found – somehow rust justifies using metal in the forest in our minds.)
We’ve got some video of it which I’ll put up soon, but in the meantime you can go check out the flickr set.
