These past 36 hours have been absolutely fabulous, and exhausting…
First there was the 7th HackersNL meeting in Utrecht. The name of the event is unfortunate, IMO (this whole “hacker” monicker doesn’t sit well with normal people, i.e. 99.9% of humanity), but the presentations were both absolutely fantastic. A wide scale of design topics by David Menting, including his “linear clock” for which he designed custom hardware based on a standard tiny Linux + WiFi board, and then a talk about turning a cheap laser cutter into a pretty amazing unit by ripping out the driver board and software, and replacing it with their own custom hardware with an MBED module plus software (wiki) – by Jaap Vermaas and Peter Brier. Both cutting edge, if you pardon the pun, and above all a pressure cooker where two dozen people get to talk about “stuff”, mostly related to Physical Computing really. Everything is open source.
If you live in the neighborhood of Utrecht, I can highly recommend this recurring meeting, scheduled for the last Thursday of each month – so take note, hope to see you there, one day!
The other event was the Air Quality Egg Workshop, by Joe Saavedra. Basic idea: a sensor unit, to measure air quality in some way, plus an “egg” base station which can tie into Pachube (both ways), relays the sensor data, and includes an RGB color light plus push-button.
Here’s my concoction (three of the sensors were mounted away from the heat generated by the Nanode):
It’s now sitting next to the JeeLabs server, feeding Pachube periodically. We’ll see how it goes, since apparently these sensors need 24..48 hours to stabilize. Here are some of the readings so far:
What I took away from this, is:
- Whee, there sure is a lot more fun stuff waiting to be explored!
- When you put a fantastic bunch of creative people together, you get magic!
- Not enough time! Would it help to keep flying westwards to cram more hours into a day?
