Adding Touch Sensitivity To Projects

by spunkytoofers

Fortune Cookies: Series of chaotic speech synths based on the Vtech Talking Whiz Kid circuit. Each one in the series is unique and an exploration into different interfaces. The Whiz Kid when circuit bent is what I consider bends under the category of glitch stream. A device is bent into streaming a series of endless/random flow of glitches and further bends will determine the course of it’s flow or interruption of flow.

In this particular version I’m using touch sensitivity to interact with the glitch streams. It’s a pretty simple concept you can apply to any touch based project so long as your components are metal to the touch and electrically isolated from the enclosure you’re using. This works for switches but this can also work very well for momentary buttons. If you find the right connections you can add an expressive touch sensitivity to your trigger and switches.

Strip a good amount of stranded wire and wrap the wire around the component’s base on the underside of the non conductive enclosure, then tighten the component down. If components have hardware such as washers it’s pretty easy just to thread the wire in between the washer and component (given it is thin yet sturdy enough) and then just tighten the component down to the enclosure making sure the wire is making contact with the metal casing of your component. Use a multimeter or other means to check the continuity of your your wire to the touchable part of your component.
