#OktoberfestOfThings
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)

Testing our Oktoberfest prototypes at the Augustiner tent.

Back for the 2nd annual Oktoberfest of things! The Group trying to figure out how much beer we will all drink tomorrow.

Trying to improve on last year’s device by adding a bluetooth low energy chip. The device senses the tilt of the glass and sends the data to be track.

Also we are working on a sensor to try and detect the weight of the glass, so we can determine how much beer is left in the glass. We can detect if the glass in on the coaster and some changes, but the data is all over the place right now and we don’t know if it is the sensor or the coasters.

We even have custom made holders for the beer glasses!
