Cellphone charging stand

Cell phone charging stand

Lamp...or charging stand?Here is a simple solution for a common problem: where to put your cellphone while it is being charged. This multiple gooseneck floor lamp (aptly named “Hydra,” available at Home Depot) can do double duty as a cellphone charging stand, freeing up valuable shelf or desk space for more important uses. It nestles your gadget inconspicuously out of the way but still readily accessible while charging.

One caveat: this lamp has a dimmer switch, and we haven’t yet found reasonably priced dimmable compact fluorescent bulbs, so bulb options are limited to incandescent or extremely expensive.

Humane population control for feral golf balls

Natural environment
One of our neighbors is retired and, so far as we can tell, spends approximately twelve hours per day golfing. Golfing from his front lawn, that is. While he’s an agreeable fellow and we will not begin to question the motives or reason of someone that has this compulsion, we will simply observe that our neighborhood has an infestation of foam practice golf balls.

Beyond the many hundreds of balls that are successfully reclaimed each day, some dozens accumulate in the yards, bushes and hanging potted plants of our house and the houses of our other neighbors. They get stuck in the trees and bushes, confusing us when we go to pick lemons. People remember to shut the windows of their cars when they park. Sometimes it gets so bad they clog the gutters. You can even find them in places that they could have only gotten to after three reflections, leaving you quite puzzled. But, you get the idea.

Once behind a fence, they seem to have particular trouble getting out. (Especially if there’s a dog.) Case in point: This weekend we were at one of our (non-golfing) neighbors houses for a birthday barbecue. In the back yard, down below the little bushes, approximately twenty yellow balls were visible. I didn’t look hard; these were just the ones in plain view. When I pointed them out to our hosts, I learned that they had already thrown the day’s catch (a few dozen balls) back over the fence.

What do do? We decided to practice a humane method of dealing with pests: catch, tag and release.

The whole bandMany of the partygoers got involved in the process. Most of the balls were tagged with simple designs, but some were quite elaborate. We particularly liked this set (which we didn’t make), showing four foam balls as members of Kiss. We tossed them over the fence, and they disappeared early in the morning. We’re waiting to see if any of the tagged ones reinfest the yard, or if we get new ones every day.

If our golfing neighbor is sufficiently annoyed by people writing on his little foam balls, it may even be effective as a means of population control.

 

Evilmadscientist Linkdump: May 2007

Today we have a fine crop of choice links, hand picked at the point of perfection, for your viewing pleasure:

  • First, a neat article from The Times Online about 3D printing, that gives a nice mention to the CandyFab 4000
  • A Video Compilation of the short list of video finalists for the Phylm prize (of which we are among the judges).
  • Suggested by Brian Gaut: the cartalator. That’s the shopping cart escalator found at Target and a few other big box stores. (I’ve seen them for years, but I’ll admit to thinking it was really cool when I first saw one.)
  • Bookend snippets from the Japanese children’s program, Pythagoras Switch (suggested by an anonymous reader). These are Rube Goldberg machines based on rolling balls and you simply mustwatch these videos if you have not seen them– plan fifteen minutes where you don’t need to pay attention to anything else. The folks that make these videos have the coolest job in the world.
  • Translations in many languages of that most useful of phrases, “My hovercraft is full of eels.”
  • Seriously disturbing Lego, but made with remarkable talent. (Additional pictures in gallery.)
  • There is actually a formula to compute actual size of a #6 (for example) screw!

We are also inducting several new Honorary Mad Scientists into the fold today:

  • Graham Stabler who makes all kinds of amazing things including tiny flying machines and homebrew CNC machines.
  • John Maushammer, who has among other projects, developed the Pong Watch
  • Bruce Shapiro, whose motion control art installations are truly remarkable
  • Christy Canida, who has made remarkable strides in instructing the world in good cooking and strange taxidermy– a combination that certainly qualifies for mad scientist status!
  • Raven Hanna, a molecular biophysicist turned artist– our brand of Mad Science exactly. She now runs Made with Molecules (Go get your molecules on.)

I want this toy.

I’ve always been a big fan of marble runs, starting with the Gravitram in Portland, Oregon (pictures), all the way up to the modern marvels like this one by Matthias Wandel. While I’ve been dreaming about making my own amazing machine, a toy company in the UK has gone ahead and made it easy. Take a look at this amazing line of Techno-Ball sets by Cheatwell Games– in sizes from a diminutive 173 pieces to the 920 piece monster pictured here– with two independent motorized marble-lifting chains. (I want the big set. Maybe two.)

It looks like these are easy to get in the UK, even from Amazon.co.uk, but it’s not obvious that they’re even for sale in the states.

So, I’d like to ask: does anyone know where I can order a set (or two)?

Update:

A reader left a comment about Steve Jackson’s Chaos Machine— a giant ball-run construction toy that he brings to conventions. It’s apparently so cool that it has its own fansite.

The Chaos Machine is made out of a number of Chaos Tower sets from chaostoy.com. The sets can be built in a number of configurations, like the six-foot-tall one pictured to the left. This looks like a really fabulous construction system– enough so to change my mind about which set to get! The tracks look a lot nicer than the ones in the techno-ball set, and it has all the features of “real” marble runs: trampolines and catchers, vortices, switches, accumulators, a series of tubes, and probably more that I can’t see in the photos.

So… can anyone beat that?

Weekend project: Phylm contest entry

As we mentioned before, the deadline for the entering the Phylm contest is 12:00 am (GMT) May 1, 2007 extended to May 14, 2007, which is rapidly approaching. That leaves you just one weekend two weeks! We know that many people work better under a deadline, so our challenge to you is to make this your weekend project. We’re sure you can put together a two and a half minute film featuring physics over the weekend. So, let’s see your submissions!

Videos will be judged on clarity, accuracy, and creativity. The winner will receive a check for $100 (US) to be dispersed in June 2007. Once again, you can watch the video announcement at YouTube or (embedded) here:

How to Find Dry Ice for Your Projects

Bubble Wok Whether you’re floating bubbles on carbon dioxide, making a cloud chamber or wanting to keep the contents of your freezer frozen during a power outage, you are going to need dry ice. We’ve gotten a lot of questions about where to get dry ice. We found our local dealer by stumbling on a flyer at the grocery store, which isn’t the most reliable method. Luckily, we’ve found a fantastic resource for you (if you’re in the US): Airgas has a dry ice retailer locator on their website.

We have had mixed luck just showing up at the store (and one long dry ice dry spell during the period after a fire at the local plant) so we recommend calling ahead to check availability. Conveniently, Airgas includes phone numbers in their retailer listings.

Here’s your obligatory warning: dry ice is cold. Dangerously cold. Don’t allow prolonged (and by prolonged, we mean anything more than momentary) contact with skin. We don’t recommend using a hard plastic cooler for transporting dry ice as the very low temperature can make it brittle and prone to cracking. A styrofoam cooler is a better option, but a nice thick towel will do nicely for insulation in transit as well.

For an added bonus, here’s the Airgas page of Cool Uses for Dry Ice. You’ve got to love an industrial supplier that has a recipe for “Witch’s Brew” on their website!

Cashew folktale

Yesterday we received an anonymous comment on our cashew story with a Sri Lankan folktale about the cashew. If this is your comment, thanks for sharing your story– Let us know who you are and we’ll give you credit!

Here is the story:

My mother told me a story (From Sri Lanka) about why the Cashew fruit has its seed on the outside.

Apparently, as God was creating the world he was approached by the Devil, who was upset that he had not been allowed to make something. So, in an act of kindness, God asked the Devil to make a fruit.

The Devil went to work and formed what we now know as the Cashew fruit. He took it to God and said, “See? I can make something just as good as your creations.”

On looking it over, God asked, “But where is the seed?”

The Devil, realising his mistake, just muttered, “Oh, I’ll stick it here.” And with that, placed the seed on the bottom of the fruit.

And there you have it.

Glenn’s Mosaic Table

Mosaic table
Glenn made this very awesome mosaic table, influenced by our Mixed-Media Mosaic Dining Table. In the table are neatly broken tiles, marbles, dice, broken tourist-trap commemorative plate shards, and other interesting goodies. =)
Mosaic table close-upHere’s a close up of some of the materials he used. There are more pictures in his project set on flickr.

PS: Glenn was kind enough to add these photos to the Evil Mad Science Auxiliary flickr photo pool. If you’ve got pictures that are (at least marginally) related to posts and projects on evilmadscientist, add them to that group, and they’ll appear now and then in the Evil Mad Science Auxiliary flickr photo badge on the right hand side of this page.
