IoT Device Pulls Its Weight in Home Brewing

Brewing beer or making wine at home isn’t complicated but it does require an attention to detail and a willingness to measure and sanitize things multiple times, particularly when tracking the progress of fermentation. This job has gotten easier thanks to the iSpindel project; an ESP8266 based IoT device intended as a DIY alternative to a costly commercial solution.

Hydrometer [Source: grapestompers.com]

Tracking fermentation normally involves a simple yet critical piece of equipment called a hydrometer (shown left), which measures the specific gravity or relative density of a liquid. A hydrometer is used by winemakers and brewers to determine how much sugar remains in a solution, therefore indicating the progress of the fermentation process. Using a hydrometer involves first sanitizing all equipment. Then a sample is taken from the fermenting liquid, put into a tall receptacle, the hydrometer inserted and the result recorded. Then the sample is returned and everything is cleaned. [Editor (and brewer)’s note: The sample is not returned. It’s got all manner of bacteria on/in it. Throw those 20 ml away!] This process is repeated multiple times, sometimes daily. Every time the batch is opened also increases the risk of contamination. Continue reading “IoT Device Pulls Its Weight in Home Brewing”

Electromagnetic Field Camp

Emf Electromagnetic Field Camp is a three-day camping festival for people with an inquisitive mind or an interest in making things: hackers, geeks, scientists, engineers, artists, and crafters.

There will be people talking about everything from genetic modification to electronics, blacksmithing to high-energy physics, reverse engineering to lock picking, crocheting to carpentry, and quadcopters to beer brewing. If you want to talk, there’ll be space for you to do so, and plenty of people who will want to listen.

EMF is a volunteer effort by a non-profit group, inspired by European and US hacker camps like CCC, HAR, and toorcamp.  This year on Friday 31st August – Sunday 2nd September 2012 Will hold the first Uk meeting of its kind.

Events and activities will run throughout the day and into the evening, everything else (chats, debates, impromptu circus performances, orbital laser launches) will run as long as your collective energy lasts.

The Event is to be held at Pineham Park, Milton Keynes, UK.

As a Hackaday viewer you can get discounted tickets.
