Hi brainiacs I have a project where I am trying to control a piezo gas starter. the piezo starter is to be retro-fitted so that I can disable the spark. I do not know yet how high the voltage goes when the starter is actuated. Any ideas about how I can turn off the spark ? A solid state approach would be preferred over a mechanical one. ( But as they say ...... any port in a storm ) Thanks AGSC Denver, CO -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
