What’s better than an ordinary end table? How about an end table that can serve you beer? [Sam] had this exact idea and used his skills to make it a reality. The first step of the build was to acquire an end table that was big enough to hold all of the components for a functional kegerator. This proved to be a bit tricky, but [Sam] got lucky and scored a proper end table from a garage sale for only $5.00.
Next, [Sam] used bathroom sealant to seal up all of the cracks in the end table. This step is important to keep the inside cold. Good insulation will keep the beer colder, while using less electricity. Next, a hole was cut into the top of the table for the draft tower.
The draft tower is mounted to a couple of drawer slides. This allows the tower to raise up and down, keeping it out of sight when you don’t want it. The tower raises and lowers using a simple pulley system. A thin, high strength rope is attached to the tower. The other end is attached to a spool and a small motor. The motor can wind or unwind the spool in order to raise and lower the tower.
The table houses an Arduino, which controls the motor via a homemade H bridge. The Arduino is hooked up to a temperature sensor and a small LCD screen. This way, the users can see how cold their beer will be before they drink it.
To actually keep the beer cold, [Sam] ripped apart a mini fridge. He moved the compressor and condenser coils to the new table. He had to bend the coils to fit, taking care not to kink them. Finally he threw in the small keg, co2 tank and regulator. The final product is a livingroom gem that provides beer on demand.
Demo video (which is going the wrong way) can be found after the break.

Kegerator ownership is awesome, but it has its downsides. It’s hard to keep track of who drank what without cans or bottles to count. [Phil] was looking for a good solution to this problem when it came to sharing beer with his roommates and friends and has just completed the first iteration of his smart kegerator.
He has devised a system based on a Raspberry Pi. His software recognizes the face of the person pulling a beer and adds a charge to their tab based on the price of the keg and the volume of the pour. The system also keeps track of current and historic temperature and humidity values inside the kegerator, and everything is displayed on a Mimo 720S touch screen.
[Phil] has a flow meter on each keg to detect and monitor pouring. This triggers the Pi camera module to run the facial recognition. The walk-through found after the jump might be a bit confusing; at the time it was recorded, the unit was only capable of facial detection. [Phil] wrote the UI in QT and C++ and used Python scripts for the flow interrupts. His plans for future iterations include weight sensors underneath the kegs, liquid probe thermometers for more accurate beer temperature readings, a NoIR Pi camera module for low light conditions, and a really snazzy UI that you’ll see on his build page.
If you don’t have a Pi, here’s an Arduino-fied kegerator that reports temperature and controls beer cooling.

Looking for a fun weekend project? How about making your very own kegerator for about $100? Well, minus the keg of course.
First you’ll need a run of the mill mini-bar fridge. These can be had for free if you prowl student neighborhoods at the end of a semester; it’s amazing what you can find being thrown out. Next you’ll have to modify it a bit: remove the shelving and pop a hole in the top. The trickiest part is building the top out of wood, although [jypuckett] shows us that it’s really not that difficult, and wood stain is your friend!
The most expensive part of the build is probably going to be the fittings, hoses, and tap, but that’s a small price to pay for your very own kegerator.
While it’s not quite as fancy as this over-engineered kegerator, the six-tap freezer chest kegerator, or as vintage as this 1950’s General Electric
fridge kegerator, it is a great example of making one for cheap, that works, and looks good.
It also raises the question: if it’s this easy to make, why haven’t you made one yet?!
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!
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.
Let’s face it, most kegerator builds go something like this: acquire old refrigerator, drill hole for tap, profit. But [GiveMeMyNickelback] recently had the opportunity to do better and he delivered. Above you can see the stylish chest freezer mod that serves up six beers on tap.
Chest freezers are perfect for these builds as their top door design helps keep the cold air inside to boost the efficiency. The trick is to modify them without messing up the insulating properties of the appliance housing. [GMMN’s] approach is a common one, build a cuff to go in between the lid and the body of the freezer. He started by building a wooden box open at both the top and the bottom. Many would have stopped there but to bring the bling he tiled the sides and front of that cuff, leaving an empty spot for the shank of each tap. With that taken care of he glued insulation to the inside of the cuff, and added weather-stripping to the bottom to seal with the top of the case. He used the holes from the lid hinge brackets to attach his add-on so that the freeze can be converted back to stock without any sign of his alterations.
We’d love to see a Bluetooth or Wifi add-on that monitors the beer volume in each keg.
