Hack a Day
Hackers are quite often the price conscious type, unwilling to pay jacked up prices for cold beverages when they can be purchased warm and in bulk for much lower cost. However, when guests are on the way and time is running out, it’s crucial to chill the drinks down to the right temperature, and fast. To take the guessing out of the process, [Álvaro Díez] and [Tibor Pal] collaborated to create the Chilled Drink Calculator.
It’s a resource jam-packed full of everything you need to know to get your drinks cold, pronto. Based on heat transfer equations and data from empirical studies, the calculator is able to show you just how long it will take to cool practically any beverage to any temperature. There are presets for different types of container and cooling method, as well as information on the ideal serving temperatures for things like wine, beer and soft drinks. There’s even information on helpful hacks to help cool things down more quickly – with the salt and ice bath being devastatingly effective with minimal equipment requirements.
Keep the calculator in your bookmarks for the next time your pals show up with a case of beer that’s been sitting in the sun all day in the back of a pickup truck (Authors note: looking at you, Terry). Alternatively, consider building an advanced cooling apparatus.

It’s always a good idea to keep a few brews in the fridge ready to go, but being able to offer your guests a fresh-poured draught beer is another step above. It’s not trivial, but with a few kegs, a freezer and the right CO2 parts, it’s achievable for the average hacker. [Ben Brooks] had a keezer (keg freezer) setup that had been doing the job quite well, but wanted to take things up a notch.
Wishing to know when it was time to start brewing more beer, [Ben] needed a way to measure how much was left in the individual kegs. Opting to weigh them, initial experiments with a hand-made capacitive sensor failed when moisture in the freezer began to ruin the sensor’s performance. Switching to a strain-gauge based setup enabled more accurate readings to be taken with no drift over time. Solenoids were added to enable the taps to be shutdown outside of beer o’clock, and a Particle Photon and Raspberry Pi were put to work to give the whole project a slick web interface. There’s even a monitor to show guests what’s on tap!
It’s a tidy improvement to a home keg setup, and ensures [Ben]’s guests won’t be left thirsty in the middle of a party. We’ve seen other instrumented beer rigs before, too. If you’re working on your own homebrewing masterpiece, be sure to drop us a line.

It is fair to say that many technologies have been influenced by human vices. What you may not realize is that vending machines saw their dawn in this way, the first vending machine was created to serve booze. Specifically, it was created to serve gin, the tipple of choice of the early 18th century. it was created as a hack to get around a law that made it harder to sell alcoholic drinks. It was the first ever vending machine: the Puss and Mew.

The folks at [K&J Magnetics] have access to precise magnetometers, a wealth of knowledge from years of experience but when it comes to playing around with a silly project like a magnetic koozie, they go right to trial and error rather than simulations and calculations. Granted, this is the opposite of mission-critical.
Once the experimentation was over, they got down to explaining their results so we can learn more than just how to hold our beer on the side of a toolbox. They describe three factors related to magnetic holding in clear terms that are the meat and bones of …read more

Over the past few years, Reddit user [callingyougoulet] has created Boozer, a DIY beer dispenser that keeps track of how much of your brew you have left in your kegs. Installed in a Keezer (a freezer that contains beer kegs and faucets) [callingyougoulet]’s dispenser uses a Raspberry Pi to keep track of things. A series of flow sensors determine how much liquid has passed through them and, when the drink is poured, can calculate how much you poured and how much you have left.
Starting with a chest freezer, [callingyougoulet] built a nice wooden surround as well as installed a …read more

Ayn Rand said, “If it’s worth doing, it’s worth overdoing.” As far as we’re concerned those are words to live by, and something that’s exemplified by most of the posts on this site. She also said some really suspect stuff about the disabled and Native Americans and reality, but you’ve got to take the good with the bad and all that.
We don’t know how much Rand [Will Weber] has read, but we’re willing to bet he’d agree about overdoing it. He recently documented a very cool 3D printed tap handle that’s designed to look like the B8 flight stick …read more

[Josh] isn’t one to refuse a challenge, especially when robots are involved. The latest dare from friends and family? Build a beer robot that can bring beverages at everyone’s beck and call.
The build consists of two main parts: the refrigerated cooler and the butler part, which comes courtesy of a Roomba Discovery from a fellow roboticist. [Josh] is basing the design on double-walled and insulated restaurant coolers. He built the refrigerated beverage hold from two stainless steel trash cans, sized an inch or so apart in diameter, and filled the gap with expanding foam insulation. He then cut away …read more

As much as today’s American beer drinker seems to like hoppy IPAs and other pale ales, it’s a shame that hops are so expensive to produce and transport. Did you know that it can take 50 pints of water to grow enough hops to produce one pint of craft beer? While hops aren’t critical to beer brewing, they do add essential oils and aromas that turn otherwise flat-tasting beer into delicious suds.
Using UC Berkley’s own simple and affordable CRISPR-CaS9 gene editing system, researchers [Charles Denby] and [Rachel Li] have edited strains of brewer’s yeast to make it taste like …read more
