Weather Station Turned Data Logger

March 15, 2011 by Kevin Dady 10 Comments

Home brewing the perfect beer (or root beer in this case) requires a watchful eye and stable temperature, but [Gregory] has a house that is 120 years old. While we are sure it is a beautiful home, it does have its usual historical issues including temperature fluctuations.

[Gregory] suspects this to be the reason why his root beer is not carbonating, but to be 100% sure he grabbed a weather station (and atomic clock) with a wireless remote thermometer and got hacking. After popping the station apart he was able to quickly isolate the radio receiver and figure out the signaling, a few connections to an arduino, and now he can keep track of the temperature as its logged on to his PC.

Hopefully he can find out if this is his issue or not. Join us after the break for a quick video.

DrunkenNES Makes A Game Out Of Getting Hammered

March 2, 2011 by Mike Nathan 5 Comments

While handheld breathalyzers are pretty novel to have around while drinking with friends, there’s nothing exciting about a $50 off the shelf unit. If you really want to grab people’s attention, you have to get creative and built something like [Batsly Adams] and his friends did.

One evening, he was casually drinking with some friends and playing around with an electronic alcohol sensor. They quickly put together a NES ROM that would play sounds, changing the pitch depending on how much alcohol the sensor detected. It quickly became apparent to them that a full-fledged breathalyzer video game was in order. In no time, he and his friends had compiled graphics, a soundtrack, and the code to drive their game, DrunkenNES.

To play the game, each player must blow into a gutted NES cartridge that has been fitted with the alcohol sensor. The Nintendo computes the player’s BAC, reporting how intoxicated they are using simple graphics and cheesy animal puns. We don’t know when the code and schematics will be made available, but when they are, you can guarantee we will be building one for “research” purposes to pair with our Power Hour shot glass.

[Thanks Adam]

Timed Shot-glass Won’t Let You Stop Drinking

March 1, 2011 by Mike Szczys 18 Comments

[Drewbagd] was inspired by the 555 timer contest and decided to make this his very first electronics project. It’s an accessory for a drinking game called the Power Hour. The game (if you could call it that) consists of contestants drinking one shot of beer every minute for one hour. [Drewbagd] points out that timing the shots can be an issue and so he decided to augment each shot glass with its own timer.

He added a base that consists of a ring of LEDs surrounding a 555 timer and the cap and resistors. This causes the timer to oscillate from illuminated for a few seconds (drink) to dark for one minute (refill). He calls it the Powered Power Hour. The video after the break shows off the functionality, and it hints at a bright future for [Drewbagd] as an infomercial Emcee.

He’s got a supporting post that detail the electronics and outline some of the prototyping issues. We were happy to hear that when he got stuck he found help over on Hackaday’s forums. Thank you to all who participate in the community by sharing their knowledge.

Quick And Easy DIY Kegerator

I think we can all agree, there are few things that go better with ~~hacking~~ everything than beer. [Tom] has taken his love for beer and building things, fusing them together in a DIY kegerator. Using an off the shelf mini fridge and some easy to find beer serving components, he walks us through the conversion step by step. When everything is said and done, the kegerator should hold two 5-gallon kegs along with the CO2 tank required to serve the beer.

The process is admittedly pretty easy, but it’s probably the quickest way to go from zero to kegerator. [Tom] has this down to a science, knowing exactly what needs to be altered and removed, so following his tutorial should save you time and headaches, should you attempt this conversion yourself.

It would be great to see this project expanded to include precision temperature controls, a method of determining how much beer remains in the kegs.

Fermentation Temperature Control

February 1, 2011 by Mike Szczys 19 Comments

[Eric Friedrich] needed to keep the wort warm enough for yeast to ferment it into beer. To solve the problem he built his own fermentation temperature controler using a microprocessor to turn some heating tape on and off. You can see the heating element embracing that diminutive fermentation bucket in the picture above. This was originally meant for keeping reptile cages warm. It costs less than similar products meant just for brewing and works well for [Eric]. A DS1820 temperature sensor gives feedback to an ATmega168 which then uses a relay to switch the heat on and off. The target temperature can be changed using a potentiometer on the board, with the setting displayed on a character LCD screen on the project enclosure.

Beer Catapulting Fridge

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.

[thanks Springuin]

Beer Shooting Dorm Fridge

blunt force traumomatic

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.
