    • “Nice hydrographs! Can you now compare your model to ‘that other hydrology groups model’?” The phd student suppresses the urge to roll her eyes. Her supervisor is asking her to go back into code-hell. That other model is written in Fortran and she works in Python. It took her two months [...]

      I try to make a point of looking on the bright side of life. But sometimes, I just ... can't. I also hate to say I told you so.... This morning I stumbled1 on recent research from Microsoft that showed that WiFi (and potentially Bluetooth and RFID) technologies can be used to measure soil [...]

      This blog is based on my keynote presentation at the Fablearn conference in Eindhoven on September 28th 2018. My eyes twinkle when I see what my students have made. I'm looking at a coil that is powerful enough to light up a fluorescent tube. A second group of students connected two pendulums in[...]

      “I saw you on the news!” I raised an eyebrow at Markus. I came to Vienna to present my research, but this happened on the first day of the #EGU17 conference. “You walked in your poster suit at the Science March, right?” I did. I arrived in Vienna early enough so I could join the [...]

      BANG I swivel my head from the javascript on my screen to the diesel engine in the back of the boat just in time to see pieces of rubber flying around. Our boatsman quickly shuts down his engine and uses our momentum to get us to the shore of the Irrawaddy river (Myanmar) that we have been [...]

      I raised an eyebrow. Wahid Palash, a Bangladeshi phd student, explained to me how he could better predict when river Ganges might flood. Strikingly, he used only information from the inflow point into Bangladesh. Frowning I ask him why he doesn’t just use the information on river Ganges from [...]

      We made a collaborative Rube Goldberg Machine! We demonstrated it live on the streets of San Francisco! Everyone knows these machine where a rolling marble tips over book, that sets a toy car in motion, that hits the on-button of a fan that blows away ... etcetera: a Rube Goldberg machine. [...]

      longboard

      5 Jun 2016

      I glued a LEDstrip to my longboard and used some magnets, sensors and Arduino's to have the LED light effects react to the speed of the board. I posted a step by step guide on how te build your own, including all code needed for the Arduino's on Instructables: [...]

      I can not count the number of times I fried electronics by "oopsing": connecting the wrong wire to the wrong connector. Twelve volt power does not go well on a three volt data input. I've learned electronics in the school of hard knocks: electrocuted fingers and all. I've learned. I now always, [...]
