At the Mobile Monday Amsterdam, which I co-organise, I did a short talk on how to build your own Internet of Things Thing, in a day. The technical process is explained in my blogpost from last year: called The MoMoMeter.
Since we videotape all our talks, it’s included here:
For Mobile Monday which I co-organise, I built a new Backchannel. Backchannels are a screen, next to thepresentation, where people in the audience can post their reactions. Our new backchannel includes posting by Twitter, SMS and photo’s via Mobypicture.
To post via Twitter, people had to include the hashtag #momo in their posts. The event was a big success, and #momo even made it to the trending topics on Twitter search!
I’m already talking to some other events, who want to use this to enhance audience participation.
Yesterday the team of Mobile Monday went to Protospace, to play with their devices in their lab. They have a big lasercutter, different computer driven milling machines, and a 3D printer. We had a tour of the lab, and went over all the machines. For example, I never realised there are shapes that can only be generated by printing them on a 3D printer.
As project for the day we decided to build a device that would respond to input from Twitter. We wanted to build something that could respond to input by the audience, and we could use at our events.
We built a meter (see first image) with a needle that moves, comparing the number of tweets for 2 different keywords, based on the Twitter Search API. It checks every 5 seconds for new tweets containing terms, calculates the new value, and updates the needle.
The board, needle and stand were cut with their lasercutting, including the nice gradient. It works beautifully, and we allready got good responses on the live stream. We’ll probably show it on one of the next Momo’s.
