Jumbo Size New Years Countdown

December 28, 2010 by James Munns 9 Comments

New Years celebrations tend to get bigger and bigger every year for most people, and [Brian] takes no exception. In order to top his lighted tree of a few years ago, he has concocted a 40’x40′ set of Seven-Segment displays made out of Christmas lights, hung from nearby trees. These displays would start counting down the minutes an hour before the ball drop, and be synchronized with music. Also in the spirit of a New Years party, the music he has chosen is in the form of a Power hour. The control board [Brian] is using also comes with two extra outputs, which he plans to use for the most exciting possible additions: Fireworks and Flamethrowers.

Be sure to check back after New Years to see a video of the device in action. Be sure to Hack, Drink, and Party Responsibly out there.

Perfect Shots Every Time

December 28, 2010 by Caleb Kraft 23 Comments

A shot is a shot right? Well, not really. Usually we see a sloppy shot poured of a single type of alcohol and, depending on our current standing with the bartender, may or may not be full to the brim. The Pousse-Cafe makes an art out of your drinks by perfectly layering several liqueurs. Not only will it measure them out perfectly, but it is voice controlled as well. There are 3 liqueurs to choose from, as they were going for a specific, visually appealing drink (otherwise, why bother?). Judging from the pictures it looks like it’s using an arduino in conjunction with a laptop for control.

You can see a video of it in action after the break.

Singing: With Plasma!

December 28, 2010 by James Munns 44 Comments

While there are many ways to produce audible sound, Plasma Speakers have to be one of the coolest. Usually very complex and expensive, we received a tip for a beginners guide to making one of these impressive novelties. Handily included are a set of schematics (one very simple schematic, the other with a few artistic illustrations). There are also a set of warnings, which include sound advice to mind the heat generated by the MOSFETs, as well as making sure that your input signal isn’t too strong. The finished product is fun to listen to, so be sure to check out the example video after the break.

Accidental LED Fabrication

December 28, 2010 by Mike Szczys 36 Comments

[Grenadier] had a piece of silicon carbide sitting around that he planned to use when making a primitive diode called a Cat’sWhisker Diode. While probing he noticed that one of the crystals threw off a bit of light. He popped it off and used JB Weld to attach it to a brass plate. The peculiar thing is that it generates light when power is run through it both forward and reverse biased. So what’s going on here? According to an informed discussion on the phenomenon there’s actually a pair of diodes in series but with their polarity reversed.

MIT Inspired Impromptu SegStick

December 27, 2010 by Greg R. Jacobs 15 Comments

If many of the readers out there longed for a Segway for Christmas but Santa didn’t bring you one, you are in luck. The aptly named Seg-Stick by [scolton] is a great way for cheap transportation. It uses a broomstick, along with two DeWalt cordless drills to power this bad boy on 6” wheels. Like articles done before on Hack a Day this is an awesome although rudimentary example of the things that can be made with a short amount of time, some determination, and a few power tools. Great job [scolton].

Build A Fusion Reactor In Your Home

December 27, 2010 by Caleb Kraft 55 Comments

At first we were pretty skeptical of this home made fusion reactor instructable. However, we’ve seen home made fusion reactors before, so it is technically possible, we guess. The construction alone is interesting enough to warrant a few moments of looking.

We’re not experts, so pardon us if we can’t tell you exactly what is going on, but we can appreciate the craftsmanship involved with the build. The vacuum chamber specifically is quite nice.

We know that some of our commenters probably have more experience here. Tell us, does this thing look legit?

Santa-Pede Challenge: Take Two

December 27, 2010 by Caleb Kraft 36 Comments

We are going to give the Santa-Pede Challenge another try. This time, you have till the end of January to do something (make it walk/crawl/scoot) with a dancing santa (or dancing musical holiday toy). As you can see in my example, it doesn’t have to be complicated or efficient in any way.

Here are some issues and questions we would like to address:

1. Many of you suggested a banner of some type to remind you.
Great idea, we were waiting for some other features to be added, but we’ve just gone ahead and popped them in. You can see the featured items at the top of the right hand column.

2. Some pointed out that the “Buy Break Build” title isn’t very hack-ish since we often preach up-cycling.
yeah, we really think you should find these santas anywhere. The alliteration is fun though isn’t it?

You can get all the rules by going to the original post. Just note that the last date for entries will be January 31.
