#hybrislabs Oktoberfest of Things table

Sven Haiges and the Hybris Labs crew built an awesome table with Internet-connected beer coasters using the SparkCore. Check their detailed blog post and source code.

Why focus on the Masskrug?

The #OktoberfestOfThings 2014 hackday is now scheduled and more people start thinking about bringing Internet of Things technology to the Oktoberfest. The question came up, why the project is focused on the Masskrug. How about adding sensors to tables and tents?

Beer made us start this project, so the Masskrug was a natural focus. But if you think about the Oktoberfest as an environment, the Masskrug is also the single most standardised item you’ll find in the field. Choosing it as our “ecological” niche makes it easier for clever solutions and shared results to spread. And as this is an unsolicited bottom-up initiative, ownership and control come into play. At least while you hold on to it, the Masskrug is a personal item. Enhancing it might thus be less intrusive to other people’s experience and (perceived) privacy, than fiddling with tables or tents.

If you want to give it a try, here are some requirements we found helpful in past events. Of course, all this is not set in stone. Build whatever you think makes most sense and see how it works in the field, for you and others.

See you soon, to learn, make and share!

2014 challenge

We’re planning the 2014 edition of the #OktoberfestOfThings project.

The mission is still the same: ”Investigating ways to connect a beer to the Internet. Towards a field test under the hardest possible conditions.”

Here are the Masskrug requirements.

As this year we saw a lot of industry consortiums and closed gardens being established, we’ll try to counter this with an open, loosely coupled Web of connected beers, based on HTTP and Webhooks.

Bring your Arduino, SparkCore, Imp or any other REST based IoT device.

We plan a meetup in Munich on Sept 18th, a test run in a beer garden Sept 19th and visiting the Fest Sept 20th.

Some of the drinking behaviours stored during the Oktoberfest. Connectivity was not existing at the Oktoberfest tents, so we couldn’t store more information using the GSM shield.

We’re at Maker Faire Rome

The field test was quite fun. BLE worked fine, but connectivity to the Web (via smartphone 3G) was zero. The plexiglass adapter suffered some Prosit-inflicted damage. We found a quick fix, but the design could probably be improved with this in mind.

Formalized Requirements

An #OktoberfestOfThings Masskrug must be

[R1] safe for drunk operation (no electro-shocks, no poked-out eyes)

[R2] battery powered (there’s no power sockets)

[R3] detachable (you cannot bring your own Masskrug)

[R4] connected (sensor measurements accessible on the Web)

[R5] open (measurements available in an open format like CSV, JSON or XML)
