| + | **Camera obscura workshop:** | ||
| + | |||
| + | Camera obscura "model 1" made from extremely cheap materials: | ||
| + | - lens from Chinese 1-euro shop | ||
| + | - disposable cardboard from supermarket wastebin | ||
| + | - glue | ||
| + | - ducktape. | ||
| + | |||
| + | {{:summit:camera_obscura_model_1_picture.jpg|}} | ||
| + | |||
| + | You can see that the projection gives a nice lomo effect. | ||
| + | |||
| + | {{:summit:preimages:camera_obscura_model_1.jpg|}} | ||
| + | |||
| + | I have "perfected" the design for easier construction. This is "model 2". | ||
| + | Model 2 is simpler to construct, more solid and gives a better and bigger picture. | ||
| + | Now it is possible to draw the scene that you see on the transparent paper. | ||
| + | You can see my simple drawing in the lower left corner. | ||
| + | |||
| + | {{:summit:preimages:camera_obscura_model_2_and_drawing.jpg|}} | ||
| + | |||
| + | At the workshop I will try to make Model 3 - which should be even easier to use for drawing, but more difficult to construct because it uses an extra mirror. | ||
| + | |||
| + | **Parabolic microphone workshop:** | ||
| + | |||
| + | We will experiment with an extremely simple parabolic microphone consisting of: | ||
| + | - an op-amp preamplifier kit - ready to be soldered | ||
| + | - a miniature microphone | ||
| + | - some wires and audio connector | ||
| + | - a 9v battery | ||
| + | |||
| + | I have ordered 6 kits. | ||
| + | The umbrella we will have to find somewhere in a shop. I will bring only two umbrellas myself. | ||
| + | |||
| + | {{:summit:preimages:parabolic_microphone_setup.jpg|}} | ||
| + | {{:summit:preimages:parabolic_microphone_detail.jpg|}} | ||
| + | |||
| + | Although it is just a preamplifier, the kit is powerful enough to drive headphones. | ||
| + | This contraption is sensitive enough to detect an audio source at the other side of the room that I cannot hear unaided. | ||
| + | I suspect that the frequency performance is poor, because a 1000Hz source is amplified less than an 500 HZ source. | ||
| + | |||
| + | **Observation workshop** | ||
| + | |||
| + | Just a few book sources for scientific enjoyment of the city: | ||
| + | - Lower left: the classic physics observation books of Marcel Minnaert | ||
| + | - Lower right: the classic nature observation books of Nico Tinbergen | ||
| + | - Upper right: the classic geology observation book of P. van der Lijn | ||
| + | - In between: some modern like minded observers and explorers: | ||
| + | - urban flora | ||
| + | - lichens | ||
| + | - clouds | ||
| + | - waves | ||
| + | - sun, moon + stars = classic navigation | ||
| + | - urban geology | ||
| + | |||
| + | Just a few sources for my talk + walk ... | ||

| + | **Camera obscura workshop:** | ||
| + | |||
| + | Model three. A bit fidgety to construct but easier to use for drawing. | ||
