This is a really powerfull microscope made in the hacteria workshop,and it is made only of a digicam.It’s really cheap,easy to make and easy to use!
At the last day of this workshop they plan to get these devices out of the lab and use it in public spaces, for viewing materials like pond water,sewage,rust on buses, normal drinking water,etc involving the public aswell.
Similar devices are also being proposed in the area of public health, for quick and interactive medical works like blood test (it can detect micro-particles like maleria virus).
I think it is a very interesting interaction with public spaces or even spaces in general, and is also quite different from what we have been doing. Since the workshop runs on a very flexible basis, each one of us should go and check these things out.
