The Spiral Data Tato -- A Curiously Complex Origami CD Case - The World's Biggest Show & Tell - art, craft, diy The Spiral Data Tato -- A Curiously Complex Origami CD Case - The World's Biggest Show & Tell - art, craft, diy With most origami models, you start with a piece of paper and move from step to step, making landmark creases and folding this part to that. And this model can be folded that way. Trouble is, the American letter paper version starts out dividing the width of the paper into nine even sections; the A4 version needs eleven even sections. I could show you how that works, but it involves math and a leap of logic or two and maybe 90% of the readers will click out at that point.

MAKE: Blog: Homemade air conditioner MAKE: Blog: Homemade air conditioner Franco writes – I completely changed the design of the earlier version. For this DIY Air Conditioner, I made a channel-shaped heat exchanger to optimize cooling. Materials used: • Aluminum repair roll ($10-15) • Nuts, bolts, and washers ($5-10) • Waterproof silicone ($5-10)Total cost: $20-35The heat exchanger is made from straight sections of aluminum (cut from the repair roll) bent into a U-shape, and bolted together, as shown (Figure 1, 2, 3). Silicone was used to seal the gaps along the edges and around the bolts.

During the 1970s, magazines published in Communist Czechoslovakia were controlled by the state, like the majority of other enterprises. Very few good magazines were available and were difficult to get hold of, so people would borrow and exchange them when given the opportunity. This also applied to magazines aimed at young people, which was probably one of the reasons why almost everyone from my generation, when we get on to the subject of pinhole cameras, has fond memories of the cut-out paper camera known as Dirkon*, published in 1979 in the magazine ABC mladých techniků a přírodovědců [An ABC of Young Technicians and Natural Scientists]. Its creators, Martin Pilný, Mirek Kolář and Richard Vyškovský, came up with a functional pinhole camera made of stiff paper, designed for 35 mm film, which resembles a real camera.

Today we are going to learn how to build a DIY light tent for product photography, for next to zero cost. Even saying it costs "$10" is a bit of a stretch, because you can probably build this mostly for free. The ten dollars assumes you cannot scrounge a cardboard box and some white tissue paper you have saved in the gift-wrap supplies box. You can get this stuff at an office supply store, but it is more fun to scrounge.
