![]() ![]() A 1997 Coca-Cola ad, directed by Industrial Light & Magic, involves the use of a computer-generated imagery pinscreen.In Tiny Toon Adventures, Elmyra (Voiced by Cree Summer) is seen using a pinscreen on her belly.In the 1990 film Darkman, a pinscreen is used to duplicate a character's hand.Charlie ( Judge Reinhold) pushes his face into it and sticks out his tongue. In the 1988 film Vice Versa, Marshall Seymour keeps a pinscreen on his office desk.The pinscreen was popularized in the 1985 music video for the Midge Ure song " If I Was", which included a giant body-sized version.This screen is like a large 3D drawing pad that can work with different sizes of paintbrushes for calligraphy. Ī giant 4' × 8' pinscreen is at the Swiss Science Center Technorama in Winterthur, Switzerland. Pinscreens have also been used for animation production a larger device working on a similar principle was invented by Claire Parker in 1935. The original Pinscreen toys were made of metal pins, which were heavier and tended to bend easily newer Pinscreen toys are generally made of plastic pins. Other similar product names are "PinPressions" and "Pinhead". It consists of a boxed surface made of a crowded array of pins that are free to slide in and out independently in a screen to create a three-dimensional relief. A single actuator would be much slower, but that is not a huge priority and could be acceptable.Pin Art or Pinscreen is an executive toy patented in 1987 by Ward Fleming. Hundreds of pins could grow the price to a level a bit outside this project's scope. On first glance for linear actuators, size would be the challenge as well as cost. ![]() That is where I'd need the pins to be actuated. The second version would be able to export a 3D map directly to the pin table from CAD. It would remove a step of making the mold. The simple version would allow you to simply imprint an existing object into the pin table and then immediately lay a substrate (fiberglass/clay/carbon fiber) directly on to the pins (over a release sheet). ![]() The goal of this project is to make a rapid prototyping table. ![]() I suppose if each pin had a small amount of tension applied before fully locking them that it would be enough to use a single head to move each pin based on x/y coordinates. Once the pins are in their correct locations, I planned on locking their position with a third perforated panel using a thumbscrew to put pressure on the pins to keep them from moving. My question is, if you had to, how could you individually actuate/move the pins from a set 0 starting point to a variable, controlled distance? I am looking at a device similar to one of those novelty pin imprint toys seen here: Limit the use of engineering jokes.Ĭall for Engineers: Tell us about your job!
