HELP!! Ive finally completed my TCT but now I have a problem. I built a mat switch to trigger the prop which works great but Im afraid it wont be on long enough to generate the scares Im looking for, say for instance someone steps on and off the mat quickly, the prop will not have time to fully open and will lose the startle factor. I have a hacked motion sensor I could use but would like to use it for other things. Any ideas?
