X.L presents DIY Pulse Oximeter created at the Open Knowledge Festival, Helsinki, FI

The wonderful team at the Open Knowledge Foundation  has just announced  the follow up event to last years’s OK Fest in Helsinki, FI. The “OK Con” will held in Geneva, Switzerland, September 17 – 18.

The DIY pulse oximeter  I’m presenting in the picture above, was produced from scratch (including etching the circuit board) in just a few hours at workshop I led at the OK Fest.  We cobbled together the hardware design and code from existing projects, but  there was also a lot of original thinking in our project and I don’t know of anyone who had created one powered by an Arduino and using an Android phone as the engine for the graphics display before us.

It’s a great testament to what’s possible when folks from all these different  open knowledge sectors  are brought together to imagine what’s next for the world.

I’ll be  expecting lots more of the same  in Geneva.


Lots of community wisdom in the house at the #ButterflyPark build. Together, these two have lived in the neighborhood more than 110 years!
