gustav Posted November 18, 2017 Share Posted November 18, 2017 I am restoring an art/robot piece made by Henk Gosses , i think from around 1995 for his family . The wire chassis measures 0.50x0.50x0.50 m , or around 2x2x2 feet , it is hard-soldered together . In the center a rubber black painted mask is suspended by springs and connected by wires via pulleys to a row of 8 electro-magnets , these are controlled with 8-fold camshaft switch . The camshaft runs continuously with an electromotor making a random crackling switch sound . Sofar nothing else happens , but when you make a hard noise , the electronic handclap switch energizes the camshaft switch and the electro-magnets start pulling the wires , in a semi-random pattern , twitching the rubber mask with a lots of sound from the clicking magnets reverberating throughout the wire frame . It is almost a scary experience for the unsuspecting onlooker , so a real Henk Gosses trademark !!! On the website of Henk there are more pictures of another Twitch version , so i think he made at least 2 Twitches . http://www.danefield.com/alpha/misc/sfx/robots.html I have also another wire mounted rubber mask piece to restore , but this one rotates the face , but this one i still have to research how it (should ) work .
