The Lunchtime Clock

The Lunchtime Clock Gives You an Extra 12 Minutes of Lunchtime

Randy Sarafan shows you how to make a Lunchtime Clock which will give you an extra 12 minutes of lunchtime.

The lunchtime clock slows down every day 20% at 11:00 and speeds up 20% at 11:48 until it rights itself at 1:00. This gives you an extra 12 minutes of lunchtime to enjoy.

How-To: Ninjabread Men

Instructables user Jayefuu writes:

After seeing a picture of some similar ninjabread men cutters by Fred & Friends on I HAD to have some. Not being one to just buy something, I thought I’d have a go at making my own using strips of 0.5mm stainless steel and a jig to bend it around.

Not being a dab hand with graphics software I twisted the arm of my friend gmjhowe to make me some outlines. The ninjas in the PDF he sent me back are pure awesome, and should be a wee bit easier to make than the shapes of the originals I got my inspiration from.

Power over ethernet

Power over ethernet? There’s a shield for that.

Like making ethernet-enabled Arduino sensors, but hate running wires to power them? Well, rather than building a complicated energy-harvesting system or relying on batteries, you might want to take a look at powering them using the same Ethernet cables that are used to transmit data to them. This can be a bit messy to implement, but luckily the folks at Freetronics have cooked up this Ethernet Shield With PoE to do the dirty work for you. Just plug it in, hook up a single power supply at your router, and you are good to go!

Desktop Manufacturing

3D printing in bulk with the Makerbot Automated Build Platform

“Makerbot [ed: an awesome, DIY 3D printer project] made an upgrade for their open source 3D printer, an automated conveyor-belt to print on. Now instead of carefully minding your 3D printer, you can hit go on 100 widgets, go to sleep, and wake up with 100 fresh widgets in the morning. The home factory is go! This is truly ‘owning the means of production.'”

So consider the possibilities. Say you need 10 of that printable tool handle, or 40 of those cable clips. Or you want to build a foosball table, and print out all the plastic men. Or print your own chess set? How about printing out the plastic components of another machine all in a single batch print?

With this latest addition to the MakerBot family. Your machine will not be just a “prototyper” anymore. With the MakerBot Automated Build Platform, your MakerBot becomes a desktop personal manufacturing system making useful object after useful object.

The Automated Build Platform is available now. Get it and turn your MakerBot into your own factory! The MakerBot Automated Build Platform is a perfect match with the MakerBot MK5 Plastruder and MakerBot Filament Spindle.

Interesting Light: A Way to See the Wind….

This experimental site-specific installation illustrates alternative, sustainable ways of harnessing energy that will explore the power of the wind in the city, visualizing it as an ephemeral cloud of light. The installation is custom built, using 500 mini wind turbines to generate power, which illuminates hundreds of mounted leds, creating firefly-like fields of light, with wind visually interpreted as electronic patterns across the installation. Wind around the southbank generates the power, creating a unique and thought-provoking light art piece that will delight all ages.

Clever Mouse Trap

DIY non-lethal mousetrap using only a toilet paper tube

Blogger Chris “MacGyver” Glass isn’t bothered all that much by mice. What does irk him, though, is when the little guys disrupt a pizza dinner by scaling a chair and exploring the inside of his shirt sleeve. That’s the kind of surprise that would have most people reaching for a brown bag and hammer, but Glass had a better, non-lethal idea. It starts with a toilet paper tube:

Here’s how I caught the critter:

1. Get a toilet paper tube and crease two lines to form a flat sided tunnel.
2. Put a treat on one end of the tube: A cracker and dab of peanut butter works great.
3. Get a tall (at least 20 inches) bucket. A trash can works well.
4. Balance the tube precariously on the edge of a table or counter with the treat hanging directly over the tall sided receptacle.
5. The mouse will scurry to the treat (they like tunnels) and fall into the trap.

Set the fella loose at least a mile away from your abode.

Postnote: It worked within the hour.

Voilà! One mouse released back into the wild. He even has a solution for folks who don’t have suitable counters:

Also, folks have asked how this could work if you don’t have a counter or table. Simple: get a piece of cardboard and crease it to make a ramp up to a small trashcan.

Steel ‘Velcro’

Steel ‘Velcro’ @ New Scientist

For all its usefulness, Velcro hardly inspires excitement. But German engineers have taken inspiration from the mild-mannered fastener to create a version of the hook-and-loop concept with enough steely strength for extreme loads and environments. A square metre of the new fastener, called Metaklett, is capable of supporting 35 tonnes at temperatures up to 800 ºC, claim Josef Mair and colleagues at the Technical University of Munich, Germany. And just like everyday Velcro it can be opened up without specialised tools and used again.
