The location of this event is Houten, 10 minutes south of Utrecht:
* Theater aan de Slinger is right next to the railway station.
If you have to come by car, drive to “Kamillehof, Houten”.

The cost will be €10 for those who come only on Friday evening, or €25 if you come on both
days or Saturday-only, including a light sandwich lunch (pizza in the evenings will be extra).


Accommodation in Houten: Hotel Van der Valk (a bit far for a walk) and Bed and Breakfast.

For more options, consider a hotel in Utrecht - close to the central railway station (e.g. the Plaza Hotel) is probably most convenient. It’s a 10-minute train ride, and there are trains to/from Houten every 15 minutes.


This event will be structured as a BarCamp, i.e. highly participatory, and planned + structured at the start of the event, including 15-minute time slots for presentations, so please get in touch (better still: edit this wiki directly) if you’d like to present an idea, project, or topic:

Proposed sessions

Informal discussions about any topic deemed interesting. We can split up and discuss these in smaller groups, even in parallel in different rooms if needed. Whatever works to exchange experiences and ideas:

|_. Topic|=.Comments|_. Chairman|
|Switching 230 VAC|What good DIY options exist today, and can we improve this?|jcw|
|Traceable Standards Exchange|Is a lightweight mechanism for home calibration feasible?|martynj|
|Electronics for IT people|Volts, Amps, and Ohms: if it’s so easy, then why is it so hard?|jcw|

PS. These sessions did not take place - everyone ended up following the main presentations…

Signing Up

To get an idea how many will attend and help the organisers do their job, please add your name to this list the list is now closed. See the Doodle screendump below for details. This was not intended as commitment, the chosen venue is able to accommodate 25 people (one room) on Friday and 35 on Saturday (two rooms), so all should be well. See you on one or both of the JeeDays!
