The Lunchtime Clock Gives You 12 Extra Minutes

January 18, 2011 by Caleb Kraft 41 Comments

The Lunchtime clock is a hacked clock that pulls a sneaky little trick to get you a longer lunch. In this instructible, [Randofo] shows us how he uses an Atmega168 and a realtime clock kit from Adafruit to slow the clock down 20% starting at 11:00 and then speed it back up at 11:45, gaining you an extra 12 minutes of sweet delicious lunch. Not really sure how noticeable this would be? Check out the video after the break. This is pretty hilarious and we can actually think of a few offices where this might work. However, many offices rely on their main network server for actual time keeping leaving this as just an amusing novelty. Still, those with luddite bosses can rejoice in your new-found extended lunch.

Quiz-o-Tron 3000

January 16, 2011 by Caleb Kraft 19 Comments

Who would have known that being given the task of planning a holiday party at a wine bar would turn into a hacking project? Well, here’s how that happened. A committee was in charge of the festivities and had decided on doing a mock game show. It wouldn’t really feel like a game show unless you had a contestant lockout system where the first one to hit the button gets a light and a sound while the runners-up get nothing. This is where [RoysterBot] comes in. He built the Quiz-o-Tron from 4 “easy buttons” from staples and an Arduino. After having finished it, he found the system to be somewhat lacking in the excitement area. When a button was pressed it only lit an indicator on the main Quiz-o-Tron box. He decided to add a small circuit inside each of the Easy Buttons using a 555 timer and some LEDs to give them some better feedback. Apparently he was going to patch into the speaker as well, but didn’t have time to get that added.

Converting 8mm Film To Digital

January 15, 2011 by Caleb Kraft 24 Comments

Many of us have these old 8mm family videos lying around and many of us have lamented at the perspective cost to get them converted to digital. [Paul] came up with a pretty slick way of digitizing them himself. He cracked open an 8mm projector and replaced the drive motor with one he could run at a much slower speed, allowing him to be able to capture each frame individually with his digital camera. He’s rigged his remote shutter control to the shutter of the projector so that it would be perfectly synchronized. There’s a video of it in action on the flickr page, and a video of the full 16,000 frame clip after digitization here.

Beer Catapulting Fridge

January 10, 2011 by Caleb Kraft 21 Comments

We’re not sure where the fascination to have your libations flung at you came from, but we can’t say we’re entirely against it. This beer catapult robot (dead link try Internet Archive) will pull a cold one from its gullet and fling it to you, or in your general direction. While he doesn’t have the source code available for the Arduino bit, we’re OK with that. We’re more interested in the mechanisms at work here and there are plenty of pictures of his set up. It seems very similar in design to this one we covered back in 2007, which also appeared on” The Late Show with David Letterman”. Join us after the break to see the thing in action.

Hackaday Sort Of Going To C.E.S.

January 4, 2011 by Caleb Kraft 4 Comments

We have decided that C.E.S. just really isn’t as much of a hacker mecca as we would have wished. Sure there were brilliantly shining walls of new 3d televisions and cellphones and camcorders as far as the eye could see, but there was mainly just tons of marketing for very little innovation, and much less hacker-centric gear than we had hoped. We had fun and tried to keep things interesting, but just couldn’t justify sending people from all over the country to Vegas for a week this year.

[Greg] had planned on going anyway, so we’ll still get a few updates when he finds the bits that interest us. He should also be snapping pictures and tossing them on twitter throughout the show. Be sure to let him know what you would like to see.

Beer Shooting Dorm Fridge

When we first heard the parts list for this project, we weren’t too impressed. It has an iPhone connecting to an IObridge etc… But then we heard the next, and most important part, an air cannon and an assortment of beer. We were sold. As you can see in the video after the break, a fancy iPhone interface lets you select your beer, then dispense it into the cannon for delivery. The next step is to aim using a web cam mounted at the cannon and let ‘er rip! The beer is fired across the room and into your hands. We suspect that the amount of cranial injury, holes in the drywall, and shattered glass will greatly increase in frequency as the night goes on. Awesome.

Light Testing Facility Tour

January 1, 2011 by Caleb Kraft 3 Comments

Here’s a fun video tour of a light testing facility. Admittedly, its not as fun as watching cell phones get abused, but it is interesting. The video is only about 6 minutes long, and is mostly a narrated slide show, but is full of information. There’s plenty to learn about the bulbs themselves, as well as the testing procedures. What you can see above is a box full of LED testing units.
