When [Joey] decided to build a kegerator, he didn’t skimp. No commercial unit or simple kit would do. [Joey] wanted complete temperature monitoring, with a tap on the kegerator itself and a cooled tap remotely mounted at his bar. He started with a box freezer, which was a bit short for his purposes. Not a problem, as [Joey] cut an extended collar for the freezer from HDPE on his shopbot. The new collar gives mounting points for the beer lines, gas lines, as well as all the electronics.
Temperature control is handled by a commercial controller, however temperature monitoring is another thing altogether. An Arduino sits in a custom aluminum case on the outside of the kegerator. The Arduino reports temperature, beer type and also controls the cooling system for the beer lines. The cooling system alone is incredible. [Joey] designed everything in CAD and cut the parts out on his shopbot. Two fans sit in an aluminum air box. One fan is used to push cold air out from the freezer around the beer line. A second fan pulls air back in, keeping the kegerator/line/tap air system a (relatively) closed loop. The entire line set is insulated with 2″ fiberglass flex duct.
Temperature data and trend graphs can be monitored on the web, and [Joey] is using a Raspberry Pi to create a wall mounted status screen for his bar room. We love this build! [Joey] we’d buy you a beer, but it seems like you’ve got that covered already!
This kegerator looks like a piece of fine furniture but closer examination of the build shows that it is at least partially hacked together. As with most of the multi-keg variants on the idea this starts with a chest freezer, but it doesn’t utilize a custom collar as is often the case.
After cutting the holes in the lid of the freezer for these beer towers [Lorglath] began building a wooden frame around it using pocket hole screws. Despite his efforts to keep things plumb and square, there was some… creative… shimming done when it came time to wrap it in oak veneer boards and add the trim pieces. But knowing where to hide the flaws got him through this part of the project and onto the surface finish. Look closely at the image above, all of those scraps are cigar rings. That represents a lot of smoke!
The rings were laid down in layers, with thin resin pours between each. To achieve a smooth and clear finish a heat gun was used to level the surface and pop any bubbles that made their way into the goo. The finished version has room to store eight kegs which are connected to the octet of taps above. That’s a lot of beer to brew, and a lot to drink!
Frankly we’re tired of Arduino having a bad name here at Hackaday. So [Brian Benchoff] came up with a way to make it useful to a wider audience. His creation, which we call the HaDuino, lets you use the Arduino clone to open a tasty bottle of beer.

Online RC store Hobby King is once again encouraging people to push the limits of what quadcopters and other multirotor remote control vehicles can do. They call it the beerlift and the goal is simple: build a multirotor craft capable of carrying the greatest amount of beer (or water, everything is measured by weight).
The competition is over, but the results were spectacular. The vehicle with the largest lift capacity – pictured above – was built by [Olaf Frommann] and carried 58.7 kilograms, or nearly 128 pounds to a hover a few feet off the ground. Last year the biggest lift was a mere 47 kg with an eight-rotor craft.
It was still an impressive showing all around. The biggest lift in the 700 class – 700 mm from rotor to rotor – was done by [David Ditch] with 19.6 kg. You can check out some of the best entries below, including an amazing aerobatic quadcopter that can successfully loop carrying a cup of beer,

Afraid that if you leave the room you’ll miss the best play of the game? Now you don’t need to move your rear end in order to grab the next brewski. BREWSTER was developed to fetch cold beers from the fridge and deliver them to you automatically.
The robot started as a roomba but has been heavily repurposed with the addition of a mechanical arm on top of the chassis. This not only lets BREWSTER grip a can of beer, but it can first open the mini fridge and reach far enough inside to get one from the back. This requires no modification to the refrigerator, but the low clearance of the roomba does call for a mini-fridge sitting at floor level. Check out a demo run in the video after the break. We think the current version is running on a pre-coded route; this project is just waiting for a spin-off that has mapping and machine vision.
The alternative to this single can delivery would be to make the entire icebox into a robot.

Drawing a pitcher of frosty cold beer out of your own keg fridge is a liberating feeling which [Danodemano2] can enjoy all the time since he pulled off this 6-tap chest freezer conversion. You won’t have to kill yourself to get it done, this image shows the custom cuff sitting between the chest freezer body and lid which is where all the added hardware is anchored.
Chest freezers are popular because they’re efficient. And let’s face it, if you’re going to devote an appliance to storing cold beer you better make certain it doesn’t drive up utility bills. That’s the reason for the rigid foam insulation around the ring, with the spray foam to ensure energy isn’t lost around the openings in the wooden frame.
This design goes above and beyond the functionality from the last offering we looked at. That one had a pretty nice tile job, but the finished wood contrasts the black freezer very nicely on this one. It’s the PC fan used for circulation and the properly terminated wiring that we really like. The one thing we wonder about is the feasibility of fitting all six corneilus kegs and the carbon dioxide tank into this beast.
For those of you who might have forgotten, let’s go over the rules of Centurion. The object of the game is for every minute, for 100 minutes, drink a shot of beer. It doesn’t sound like a lot, but after completing the challenge you’ll have had 3 liters of beer (or about eight and a half 12 oz cans) in just under two hours. When [Peter] played Centurion, he found the biggest problem was – understandably – keeping track of the time and who drank what. For an upcoming weekend of drinking, [Peter] decided to solve this problem once and for all with shift registers and seven-segment displays.
[Peter]’s Centurion score box comes in two parts. The first and largest part of the build is the main board housing an ATMega8 microcontroller and a huge two digit seven-segment display to keep track of the countdown until the next shot. Two other boards house eight additional two digit seven-segment displays for each player, incremented every time a player presses a giant arcade button.
The entire build is designed around a small travel case that also holds a large battery for cordless drinking parties. Let’s just hope the project is reasonably water-resistant; we can see a lot of spills happening in the future. Check out the video demo below.
