Little led creature

It was Zpannend Zernike today, which is sort of a science fair hosted by several organizations, including UMCG hospital where I work. I went there in the afternoon with Ellis, who wanted to go to “De Jonge Onderzoekers” (Young Researchers). There, she programmed a computer and built this little led creature, made of a clothespin, a small battery, a led light and some wire.

Before that, I had a 5.5km walk and after Zpannend Zernike we went to our friends whose daughter turned 14 yesterday.
